    Non-monophyly and intricate morphological evolution within the avian family Cettiidae revealed by multilocus analysis of a taxonomically densely sampled dataset.2011Ingår i: BMC evolutionary biology, ISSN 1471-2148, Vol. 11, s. 352-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The avian family Cettiidae, including the genera Cettia, Urosphena, Tesia, Abroscopus and Tickellia and Orthotomus cucullatus, has recently been proposed based on analysis of a small number of loci and species. The close relationship of most of these taxa was unexpected, and called for a comprehensive study based on multiple loci and dense taxon sampling. In the present study, we infer the relationships of all except one of the species in this family using one mitochondrial and three nuclear loci. We use traditional gene tree methods (Bayesian inference, maximum likelihood bootstrapping, parsimony bootstrapping), as well as a recently developed Bayesian species tree approach (*BEAST) that accounts for lineage sorting processes that might produce discordance between gene trees. We also analyse mitochondrial DNA for a larger sample, comprising multiple individuals and a large number of subspecies of polytypic species.

    RESULTS: There are many topological incongruences among the single-locus trees, although none of these is strongly supported. The multi-locus tree inferred using concatenated sequences and the species tree agree well with each other, and are overall well resolved and well supported by the data. The main discrepancy between these trees concerns the most basal split. Both methods infer the genus Cettia to be highly non-monophyletic, as it is scattered across the entire family tree. Deep intraspecific divergences are revealed, and one or two species and one subspecies are inferred to be non-monophyletic (differences between methods).

    CONCLUSIONS: The molecular phylogeny presented here is strongly inconsistent with the traditional, morphology-based classification. The remarkably high degree of non-monophyly in the genus Cettia is likely to be one of the most extraordinary examples of misconceived relationships in an avian genus. The phylogeny suggests instances of parallel evolution, as well as highly unequal rates of morphological divergence in different lineages. This complex morphological evolution apparently misled earlier taxonomists. These results underscore the well-known but still often neglected problem of basing classifications on overall morphological similarity. Based on the molecular data, a revised taxonomy is proposed. Although the traditional and species tree methods inferred much the same tree in the present study, the assumption by species tree methods that all species are monophyletic is a limitation in these methods, as some currently recognized species might have more complex histories.

    A new genus and two new species of Southeast Asian Bidessini as well as new synonyms for Oceanian species (Coleoptera, Dytiscidae)2017Ingår i: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, Vol. 647, s. 137-151Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Rompindessus jenisi Balke, Bergsten & Hendrich, gen. n. et sp. n. is described from near Rompin village in West Malaysia. The new genus is characterized by the presence of an occipital line and basal pronotal striae, the presence of a thick anterior bead on clypeus and two-segmented parameres as well as by the absence of basal elytral striae, the absence of sutural line on elytron, the absence of basal epipleural transverse carina, and the absence of longitudinal elytral carina. Moreover, male pro- and mesotarsus appear stout, and distinctly dilated laterally; the pronotum is comparably long and parallel-sided and the colour of beetle conspicuous dark orange. Leiodytes kualalipis Balke, Wang, Bergsten & Hendrich, sp. n. is described from West Malaysia (Pahang) and South Vietnam (Cat Tien). It is well characterized by its large size, elongate body and the form of the median lobe. Limbodessus fijiensis (J. Balfour-Browne, 1944), comb. n. described from Fiji is a new synonym of Limbodessus curviplicatus (Zimmermann, 1927) described from Samoa.

    Dyster svävfluga åter i farten i Dalarna2007Ingår i: Fauna och flora : populär tidskrift för biologi, ISSN 0014-8903, Vol. 102, nr 3, s. 50-54Artikel i tidskrift (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    Villa occulata was found in a bog in the province of Dalarna, Sweden in 2005 and 2006. Extended search for the species in 2007 showed it to be regularly present in similar mires in the same area. This indicates that the species is resident in Sweden and opens the possibility for further studies of its poorly known distribution and biology. The species seems to be confined to bogs which may explain why it has gone largely unnoticed. The paper summarizes the present state of knowledge.

    Arbetet med donationer av insektsamlingar vid Naturhistoriska Riksmuseet2014Ingår i: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 134, s. 153-162Artikel i tidskrift (Övrig (populärvetenskap, debatt, mm))
    Abstract [en]

    We describe the work with donated insect collections at the Swedish Museum of Natural

    History (NRM) in Stockholm, Sweden. The museum receives donations yearly from

    amateur entomologists, and they are an important contribution to the enrichment of the

    collections. For the collector it is satisfying that a public institution takes on the long term

    responsibility of safeguarding the scientific value in a collection, curating and making it

    available for study. Significant donations in the last years include that of Lars Huggert

    (Hymenoptera, Coleoptera), Hans Bartsch (Diptera) and Anders N. Nilsson (aquatic Coleoptera)

    to name a few. The curatorial and digitizing workload at the Entomology collection

    are unfortunately not matched by staff funding, and as at other European museums

    volunteer work constitute vital and invaluable help. We acknowledge especially some of

    the volunteer work in the Coleoptera and Hymenoptera collections. Recently we have engaged

    with amateur entomologists by organizing taxon-specific workshops at the museum

    which has stimulated exchange and collaboration. The Hymenoptera-day was visited by 30

    participants, and the Diptera-meeting by 49. As an example of what happens with a donation

    once it reaches the museum, we describe the work with a recent Coleoptera collection

    donation by Jan Olsson, Vallentuna. A few highlights from the unidentified material,

    including the Archostematan beetle Priacma serrata (Cupedidae) and the false jewelbeetle

    Schizopus laetus (Schizopodidae), are presented as they were new to the NRM collections.

    We also bring attention to two new websites: www.naturarv.se is the webportal presenting

    digitized material in Swedish natural history collections. Both metadata on specimens and

    photos are made searchable here. We also launch a new webpage at www.nrm.se/insektsdonationer

    where we write about new donations to the Entomology collections, with Jan

    Olsson’s Coleoptera collection first out.

    Åkerjordfly, Agrotis exclamationis, identifierad som värdart för svävflugan Villa hottentotta med hjälp av DNA streckkodning (Diptera: Bombyliidae).2015Ingår i: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 136, nr 4, s. 121-130Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this study we identify Agrotis exclamationis (Linnaeus, 1758) as a host species for the bee y Villa hottentotta (Linnaeus, 1758) in Sweden. Host use and speci city for bee y species are generally very poorly known, why the hatching of a bee y of the genus Villa from an unknown Noctuid pupa caught our attention. The parasitized Noctuid pupa was found in a garden in Staffanstorp, Skåne (Sweden), in May 2015 and kept in a jar to hatch. The bee y hatched in June leaving two empty exuviae in the jar. DNA was extracted sepa- rately from both excuviae to identify the y and the host using DNA Barcoding. A 600+ bp long sequence of the gene Cytochrome oxidase subunit 1 was sequenced for both samples and queried against the reference library BOLD (www.boldsystems.org). The Noctuid host pupa was unambiguously identi ed as the common Noctuid species Agrotis exclamationis. The sequence was identical to the most common haplotype over much of Europe. The bee y pupa was identi ed as Villa hottentotta, the most common Villa species in Sweden. This added a new Noctuid species to the list of known hosts for V. hottentotta which also includes several other Noctuid genera as well as a Geometrid moth. Belonging to the sand chamber group of bee ies where the female scatter the eggs on the ground while hovering, the active host-seeking rst instar planidium larvae bene ts from having a wide host range to potentially encounter in the substrate zone.

    Species delimitation of the Hyphydrus ovatus complex in western Palaearctic with an update of species distributions (Coleoptera, Dytiscidae)2017Ingår i: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, Vol. 678, s. 73-96Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The species status of Hyphydrus anatolicus Guignot, 1957 and H. sanctus Sharp, 1882, previously often confused with the widespread H. ovatus (Linnaeus, 1760), are tested with molecular and morphological characters. Cytochrome c oxidase subunit 1 (CO1) was sequenced for 32 specimens of all three species. Gene-trees were inferred with parsimony, time-free bayesian and strict clock bayesian analyses. The GMYC model was used to estimate species limits. All three species were reciprocally monophyletic with CO1 and highly supported. The GMYC species delimitation analysis unequivocally delimited the three species with no other than the three species solution included in the confidence interval. A likelihood ratio test rejected the one-species null model. Important morphological characters distinguishing the species are provided and illustrated. New distributional data are given for the following species: Hyphydrus anatolicus from Slovakia and Ukraine, and H. aubei Ganglbauer, 1891, and H. sanctus from Turkey.

    Two new species of the megadiverse lentic diving-beetle genus Hydrovatus (Coleoptera, Dytiscidae) described from NE Thailand.2016Ingår i: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, nr 632, s. 57-66Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Here we describe two new Hydrovatus species (Coleoptera: Dytiscidae: Hydroporinae: Hydrovatini) from the province of Khon Kaen, Isan region in NE Thailand. Hydrovatus is the third most species rich genus of diving beetles (Dytiscidae). It occurs on all continents except Antarctica and now numbers 210 currently recognized species. Both new species, Hydrovatus diversipunctatussp. n. and Hydrovatus globosussp. n., were collected at lights and are only known from the type locality "Khon Kaen" (a city and province). Diagnoses based on morphology for the separation from closely related species are given together with illustrations of male genitalia and habitus photos. We provide a determination key to Old World species of the pustulatus species group and to Oriental species of the oblongipennis species group.

    Taxonomic revision of Afrotropical Laccophilus Leach, 1815 (Coleoptera, Dytiscidae).2015Ingår i: ZooKeys, ISSN 1313-2989, E-ISSN 1313-2970, nr 542, s. 1-379Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The African species of the genus Laccophilus Leach, 1815, are revised, on the basis of study of adult specimens. In all, 105 species are now recognized. A phenetic character-analysis was undertaken, which resulted in a split of the genus into 17 species groups. Diagnoses and a description of each species are given together with keys for identification of species groups and species. We also provide habitus photos, illustration of male genitalia and distribution maps for all species. New species are described as follows: Laccophilus grossus sp. n. (Angola, Namibia), Laccophilus rocchii sp. n. (Tanzania, Namibia, Botswana, Mozambique), Laccophilus ferrugo sp. n. (Mozambique), Laccophilus furthi sp. n. (Madagascar), Laccophilus isamberti sp. n.

(Gambia, Senegal, Mali, Guinea, Sierra Leone, Ivory Coast, Ghana, Benin, Nigeria, Central African Republic, Zaire) and Laccophilus transversovittatus sp. n. (Madagascar). Laccophilus restrictus Sharp, 1882, is restored as good species; not junior synonym of Laccophilus pictipennis Sharp, 1882. New synonyms are established as follows: Laccophilus continentalis Gschwendtner, 1935 = Laccophilus perplexus Omer-Cooper, 1970, syn. n., Laccophilus taeniolatus Régimbart, 1889 = Laccophilus congener Omer-Cooper, 1957, syn. n., Laccophilus adspersus Boheman, 1848 = Laccophilus vitshumbii Guignot, 1959, syn. n. = Laccophilus adspersus nigeriensis Omer-Cooper, 1970, syn. n. = Laccophilus adspersus sudanensis Omer-Cooper, 1970, syn. n., Laccophilus modestus Régimbart, 1895 = Laccophilus espanyoli Hernando, 1990, syn. n., Laccophilus flaveolus Régimbart, 1906 = Laccophilus pampinatus Guignot, 1941, syn. n., Laccophilus trilineola Régimbart, 1889 = Laccophilus simulator Omer-Cooper, 1958, syn. n., Laccophilus mediocris Guignot, 1952 = Laccophilus meii Rocchi, 2000, syn. n., Laccophilus epinephes Guignot, 1955 = Laccophilus castaneus Guignot, 1956, syn. n., Laccophilus saegeri Guignot, 1958 = Laccophilus comoensis Pederzani & Reintjes, 2002, syn. n., Laccophilus restrictus Sharp, 1882 = Laccophilus evanescens Régimbart, 1895, syn. n., Laccophilus incrassatus Gschwendtner, 1933 = Laccophilus virgatus Guignot, 1953, syn. n., Laccophilus cyclopis Sharp, 1882 = Laccophilus shephardi Omer-Cooper, 1965, syn. n., Laccophilus burgeoni Gschwendtner, 1930 = Laccophilus wittei Guignot, 1952, syn. n., Laccophilus secundus Régimbart, 1895 = Laccophilus torquatus Guignot, 1956, syn. n., Laccophilus desintegratus Régimbart, 1895 = Laccophilus sanguinosus Régimbart, 1895, syn. n. and Laccophilus flavopictus Régimbart, 1889 = Laccophilus bergeri Guignot, 1953, syn. n. = Laccophilus segmentatus Omer-Cooper, 1957, syn. n.

    Effects of management intensity, function and vegetation on the biodiversity in urban ponds2016Ingår i: Urban Forestry & Urban Greening, ISSN 1618-8667, E-ISSN 1610-8167, Vol. 20, s. 103-112Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Ponds are important elements of green areas in cities that help counteract the negative consequences of urbanization, by providing important habitats for biodiversity in cities and being essential nodes in the overall landscape-scale habitat network. However, there is relatively little knowledge about the impacts of pond management intensity, function and environmental variables on urban pond biodiversity. In this study we addressed this gap by investigating which factors were correlated with the level of biodiversity in urban ponds, indicated by species richness of aquatic insects, in Stockholm, Sweden. Our study did not confirm any direct link between the perceived intensity of management or function of ponds and overall biodiversity. However, it seems that management can influence particular groups of species indirectly, since we found that Trichoptera richness (Caddisflies) was highest at intermediate management intensity. We suggest that this is caused by management of vegetation, as the amount of floating and emergent vegetation was significantly correlated with both the overall species richness and the richness of Trichoptera (Caddisflies). This relationship was non-linear, since ponds with an intermediate coverage of vegetation had the highest richness. Interestingly, the amount of vegetation in the pond was significantly affected by pond function and pond management. The overall species richness and richness of Trichoptera were also positively correlated with pond size. Since we found that the pattern of relations between species richness and environmental variables differed between the insect groups we suggest that it will be difficult to provide overall design and management recommendations for ponds in urban green areas. Therefore, it is recommended that to provide high aquatic diversity of species in urban areas one should aim at promoting high diversity of different types of ponds with differing management and environmental factors that shape them.

    Is there a relationship between socio-economic factors and biodiversity in urban ponds? A study in the city of Stockholm2017Ingår i: Urban Ecosystems, ISSN 1083-8155, E-ISSN 1573-1642, s. 1-12Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Urban small water bodies, such as ponds, are essential elements of human socio-economic landscapes. Ponds also provide important habitats for species that would otherwise not survive in the urban environment. Knowledge on the biodiversity of urban ponds and the relationship between their ecological value and factors linked to urbanization and socio-economic status is crucial for decisions on where and how to establish and manage ponds in cities to deliver maximum biodiversity benefits. Our study investigates if the pattern of urban-pond biodiversity can be related to different socio-economic factors, such as level of wealth, education or percentage of buildings of different types. Because of lack of previous studies investigating that, our study is of exploratory character and many different variables are used.We found that the biodiversity of aquatic insects was significantly negatively associated with urbanisation variables such as amount of buildings and number of residents living around ponds. This relationship did not differ depending on the spatial scale of our investigation. In contrast, we did not find a significant relationship with variables representing socio-economic status, such as education level and wealth of people. This latter result suggests that the socio-economic status of residents does not lead to any particular effect in terms of the management and function of ponds that would affect biodiversity. However, there is a need for a finer-scale investigation of the different potential mechanism in which residents in areas with differing socio-economic status could indirectly influence ponds.

    Descriptions of species of Stegelleta Thorne, 1938 (Nematoda, Rhabditida, Cephalobidae) from California, New Zealand and Senegal, and a revision of the genus2014Ingår i: European Journal of Taxonomy, ISSN 2118-9773, Vol. 87, s. 1-19Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Populations of Stegelleta are described from California, New Zealand and Senegal. An amphimictic population from California is identified as belonging to S. incisa and compared with type specimens from Utah and an amphimictic population from Italy. One population from New Zealand is close to S. incisa but considered to represent a new species, Stegelleta laterocornuta sp. nov. It is particularly characterised by a 379–512 μm long body in females and 365–476 μm in males; cuticle divided into 16 rows of blocks at midbody (excluding lateral field); lateral field with four incisures; three pairs of asymmetrical lips, U-shaped primary axils without guarding processes, each lip asymmetrically rectangular with a smooth margin, only lateral lips have slender acute tines; three labial probolae, bifurcated at half of their length; vulva without flap; spermatheca 17–31 μm long; postuterine sac 7–24 μm long; spicules 21.5–23.5 μm long. Other specimens from New Zealand are identified as belonging to S. tuarua. A parthenogenetic population from Senegal is identified as belonging to S. ophioglossa and compared with type specimens from Mongolia and records of several other populations of S. ophioglossa. The generic diagnosis is emended and a key to the species of Stegelleta is provided.

    Redescription of Ganaspis brasiliensis (Ihering, 1905), new combiantion, (Hymenoptera: Figitidae) a natural enemy of the invasive Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae)2016Ingår i: Proceedings of the Entomological Society of Washington, ISSN 0013-8797, Vol. 118, nr 1, s. 1-13Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The new combination of Ganaspis brasiliensis (Ihering, 1905) is proposed, and the species is redescribed from historical specimens taken in the Neotropical Region as well as more recent specimens reared from Drosophila suzukii Matsumura, 1931 in South Korea. Drosophila suzukii, otherwise known as the spotted-wing Drosophila, is a major pest of soft fruits the world over, and the search for effective natural enemies of this fly are ongoing. Though not parasitoids of D. suzukii, we also propose the following new combinations: Dieucoila brasiliensis (Kieffer, 1909), new combination, and Dieucoila brasiliana (Weld, 1952), new combination. After summarizing all known species of Eucoilinae with the specific epithet ‘brasiliensis’, we encourage future researchers to avoid this name in order prevent nomenclatural confusion.

    The description of Garudella Buffington and Forshage, new genus (Hymenoptera: Figitidae: Eucoilinae)2014Ingår i: Proceedings of the Entomological Society of Washington, ISSN 0013-8797, Vol. 116, nr 3, s. 225-242Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Garudella, a remarkable new genus of eucoiline wasp is described from Thailand, Laos, and the Republic of Congo. Four new species of Garudella are described as well: G. acothonaspis, G. afrotropica, G. algo, and G. alicae. Several autapomorphies distinguish this genus from other eucoiline genera: a distinctly protracted and broadened pronotal plate; a massive, posteriorly protruding prop- odeum; reduced posterior rim of metapleuron; reduced scutellar foveae and lack of lateral bar “windows”; and a generally reduced scutellar plate. In addition, the posterior of the head has a distinctly curved occipital impression, resulting in the cuticle surrounding the foramen magnum to be extruded into a neck-like process. The biology of Garudella is unknown, but based on phylogenetic inference from morphology, the presumed host could be a cyclorrhaphous Diptera in a saprophagous environment.

    A Revision of Zaeucoila Ashmead (Hymenoptera, Figitidae), Parasitoids of Agromyzidae (Diptera): New Species, Identity, Distribution, and Hosts2017Ingår i: Proceedings of the Entomological Society of Washington, ISSN 0013-8797, Vol. 119, nr 3, s. 317-397Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The eucoiline genus Zaeucoila Ashmead is revised. Following a re- evaluation combining previously published phylogenetic data and new specimens, Agrostocynips D ́ıaz is synonymized with Zaeucoila. All species included in Zaeucoila are systematically treated, and now amounts to twelve, seven of which are described as new here: Zaeucoila bitiburculata new species, Z. fidalgoii new species, Z. infuscata new species, Z. johnsonii new species, Z. lignys new species, Z. normae new species, Z. patera new species. The following new combinations are proposed and species redescribed: Zaeucoila grenadensis (Ashmead), new combination; Z. robusta (Ashmead), new combination; Z. flavipes (Ashmead), new combination. Agrostocynips diastrophi (Ashmead), Agrostocynips clavatus D ́ıaz, and Agrostocynips enneatoma (D ́ıaz) are new synonyms of Zaeucoila robusta. Zaeucoila incompleta (Kieffer), Z. triangu- lifera Kieffer, and Z. unicarinata Ashmead are redescribed. Zaeucoila is an unusual genus of Zaeucoilini in its wide distribution area: it can be found from southern Argentina well into the eastern United States and southern Canada; no other zaeucoiline genus shows such a pattern. Host records and geographic data for Zaeucoila are brought up to date, as well as a key to species. Zeucoila are primary parasitoids of Agromyzidae, including Liriomyza trifolii and other species that are notable economic pests of agriculture. Tropideucoila fulvonotata (Kieffer) is transferred to Marthiella (new combination).

    The utility of CAD in recovering Gondwanan vicariance events and the evolutionary history of Aciliini (Coleoptera: Dytiscidae).2014Ingår i: BMC Evolutionary Biology, ISSN 1471-2148, E-ISSN 1471-2148, Vol. 14, nr 5, s. 1-18Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    Aciliini presently includes 69 species of medium-sized water beetles distributed on all continents except Antarctica. The pattern of distribution with several genera confined to different continents of the Southern Hemisphere raises the yet untested hypothesis of a Gondwana vicariance origin. The monophyly of Aciliini has been questioned with regard to Eretini, and there are competing hypotheses about the intergeneric relationship in the tribe. This study is the first comprehensive phylogenetic analysis focused on the tribe Aciliini and it is based on eight gene fragments. The aims of the present study are: 1) to test the monophyly of Aciliini and clarify the position of the tribe Eretini and to resolve the relationship among genera within Aciliini, 2) to calibrate the divergence times within Aciliini and test different biogeographical scenarios, and 3) to evaluate the utility of the gene CAD for phylogenetic analysis in Dytiscidae.

    Results

    Our analyses confirm monophyly of Aciliini with Eretini as its sister group. Each of six genera which have multiple species are also supported as monophyletic. The origin of the tribe is firmly based in the Southern Hemisphere with the arrangement of Neotropical and Afrotropical taxa as the most basal clades suggesting a Gondwana vicariance origin. However, the uncertainty as to whether a fossil can be used as a stem-or crowngroup calibration point for Acilius influenced the result: as crowngroup calibration, the 95% HPD interval for the basal nodes included the geological age estimate for the Gondwana break-up, but as a stem group calibration the basal nodes were too young. Our study suggests CAD to be the most informative marker between 15 and 50 Ma. Notably, the 2000 bp CAD fragment analyzed alone fully resolved the tree with high support.

    Conclusions

    1) Molecular data confirmed Aciliini as a monophyletic group. 2) Bayesian optimizations of the biogeographical history are consistent with an influence of Gondwana break-up history, but were dependent on the calibration method. 3) The evaluation using a method of phylogenetic signal per base pair indicated Wnt and CAD as the most informative of our sampled genes.

    Phylogenomic Resolution of the Hemichordate and Echinoderm Clade2014Ingår i: Current Biology, ISSN 0960-9822, E-ISSN 1879-0445, Vol. 24, s. 2827-2832Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Ambulacraria, comprising Hemichordata and Echinodermata, is closely related to Chordata, making it integral to understanding chordate origins and polarizing chordate molecular and morphological characters. Unfortunately, relationships within Hemichordata and Echinoder- mata have remained unresolved, compromising our ability to extrapolate findings from the most closely related molecular and developmental models outside of Chordata (e.g., the acorn worms Saccoglossus kowalevskii and Ptychodera flava and the sea urchin Strongylocentrotus purpuratus). To resolve long-standing phylogenetic issues within Ambulacraria, we sequenced transcriptomes for 14 hemichordates as well as 8 echinoderms and complemented these with existing data for a total of 33 ambulacrarian operational taxonomic units (OTUs). Examination of leaf stability values revealed rhabdopleurid pterobranchs and the enteropneust Stereobalanus canadensis were unstable in placement; therefore, analyses were also run without these taxa. Analyses of 185 genes resulted in reciprocal monophyly of Enteropneusta and Pterobranchia, placed the deep-sea family Torquaratoridae within Ptychoderidae, and confirmed the position of ophiuroid brittle stars as sister to asteroid sea stars (the Asterozoa hypothesis). These results are consistent with earlier perspectives concerning plesiomorphies of Ambulacraria, including pharyngeal gill slits, a single axocoel, and paired hydrocoels and somatocoels. The resolved ambulacrarian phylogeny will help clarify the early evolution of chordate characteristics and has implications for our understanding of major fossil groups, including graptolites and somasteroideans.

    Xenacoelomorpha is the sister group to Nephrozoa2016Ingår i: Nature, ISSN ISSN: 0028-0836, Vol. 530, s. 89-93Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The position of Xenacoelomorpha in the tree of life remains a major unresolved question in the study of deep animal relationships1. Xenacoelomorpha, comprising Acoela, Nemertodermatida, and Xenoturbella, are bilaterally symmetrical marine worms that lack several features common to most other bilaterians, for example an anus, nephridia, and a circulatory system. Two conflicting hypotheses are under debate: Xenacoelomorpha is the sister group to all remaining Bilateria (= Nephrozoa, namely protostomes and deuterostomes)2,3 or is a clade inside Deuterostomia4. Thus, determining the phylogenetic position of this clade is pivotal for understanding the early evolution of bilaterian features, or as a case of drastic secondary loss of complexity. Here we show robust phylogenomic support for Xenacoelomorpha as the sister taxon of Nephrozoa. Our phylogenetic analyses, based on 11 novel xenacoelomorph transcriptomes and using different models of evolution under maximum likelihood and Bayesian inference analyses, strongly corroborate this result. Rigorous testing of 25 experimental data sets designed to exclude data partitions and taxa potentially prone to reconstruction biases indicates that long- branch attraction, saturation, and missing data do not influence these results. The sister group relationship between Nephrozoa and Xenacoelomorpha supported by our phylogenomic analyses implies that the last common ancestor of bilaterians was probably a benthic, ciliated acoelomate worm with a single opening into an epithelial gut, and that excretory organs, coelomic cavities, and nerve cords evolved after xenacoelomorphs separated from the stem lineage of Nephrozoa.

    Opsin evolution in the AmbulacrariaIngår i: Marine Genomics, ISSN 1874-7787, E-ISSN 1876-7478Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Opsins — G-protein coupled receptors involved in photoreception — have been extensively studied in the animal kingdom. The present work provides new insights into opsin-based photoreception and photoreceptor cell evo- lution with a first analysis of opsin sequence data for a major deuterostome clade, the Ambulacraria. Systematic data analysis, including for the first time hemichordate opsin sequences and an expanded echinoderm dataset, led to a robust opsin phylogeny for this cornerstone superphylum. Multiple genomic and transcriptomic resources were surveyed to cover each class of Hemichordata and Echinodermata. In total, 119 ambulacrarian opsin sequences were found, 22 new sequences in hemichordates and 97 in echinoderms (including 67 new sequences). We framed the ambulacrarian opsin repertoire within eumetazoan diversity by including selected reference opsins from non-ambulacrarians. Our findings corroborate the presence of all major ancestral bilaterian opsin groups in Ambulacraria. Furthermore, we identified two opsin groups specific to echinoderms. In conclu- sion, a molecular phylogenetic framework for investigating light-perception and photobiological behaviors in marine deuterostomes has been obtained.

    PESI - a taxonomic backbone for Europe2015Ingår i: Biodiversity Data Journal, ISSN 1314-2836, E-ISSN 1314-2828, Vol. 3, s. 1-51, artikel-id e5848Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations, however, presents a serious challenge for end-users of taxonomic concepts. Users need standardised and continuously harmonised taxonomic reference systems, as well as high-quality and complete taxonomic data sets, but these are generally lacking for non-specialists. The solution is in dynamic, expertly curated web-based taxonomic tools.

    The Pan-European Species-directories Infrastructure (PESI) worked to solve this key issue by providing a taxonomic e-infrastructure for Europe. It strengthened the relevant social (expertise) and information (standards, data and technical) capacities of five major community networks on taxonomic indexing in Europe, which is essential for proper biodiversity assessment and monitoring activities. The key objectives of PESI were: 1) standardisation in taxonomic reference systems, 2) enhancement of the quality and completeness of taxonomic data sets and 3) creation of integrated access to taxonomic information.

    This paper describes the results of PESI and its future prospects, including the involvement in major European biodiversity informatics initiatives and programs.

    Genetic signs of multiple colonization events in Baltic ciscoes with radiation into sympatric spring- and autumnspawners confined to early postglacial arrival2014Ingår i: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758, Vol. 4, nr 22, s. 4346-4360Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Presence of sympatric populations may reflect local diversification or secondary contact of already distinct forms. The Baltic cisco (Coregonus albula) normally spawns in late autumn, but in a few lakes in Northern Europe sympatric autumn and spring- or winter-spawners have been described. So far, the evolutionary relationships and taxonomic status of these main life history forms have remained largely unclear. With microsatellites and mtDNA sequences, we analyzed extant and extinct spring- and autumn-spawners from a total of 23 Swedish localities, including sympatric populations. Published sequences from Baltic ciscoes in Germany and Finland, and Coregonus sardinella from North America were also included together with novel mtDNA sequences from Siberian C. sardinella. A clear genetic structure within Sweden was found that included two population assemblages markedly differentiated at microsatellites and apparently fixed for mtDNA haplotypes from two distinct clades. All sympatric Swedish populations belonged to the same assemblage, suggesting parallel evolution of spring-spawning rather than secondary contact. The pattern observed further suggests that postglacial immigration to Northern Europe occurred from at least two different refugia. Previous results showing that mtDNA in Baltic cisco is paraphyletic with respect to North American C. sardinella were confirmed. However, the inclusion of Siberian C. sardinella revealed a more complicated pattern, as these novel haplotypes were found within one of the two main C. albula clades and were clearly distinct from those in North American C. sardinella. The evolutionary history of Northern Hemisphere ciscoes thus seems to be more complex than previously recognized.

    A new colorful species of Geophagus (Teleostei: Cichlidae), endemic to the rio Aripuanã in the Amazon basin of Brazil2014Ingår i: Neotropical Ichthyology, ISSN 1679-6225, E-ISSN 1982-0224, Vol. 12, nr 4, s. 737-746Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Geophagus mirabilis, new species, is endemic to the rio Aripuanã drainage upstream from Dardanelos/Andorinhas falls.The new species is distinguished from all other species of the genus by the presence of one to five large black spots arrangedlongitudinally along the middle of the flank, in addition to the black midlateral spot that is characteristic of species in thegenus and by a pattern of iridescent spots and lines on the head in living specimens. It is further distinguished from allcongeneric species, except G. camopiensis and G. crocatus, by the presence of seven (vs. eight or more) scale rows in thecircumpeduncular series below the lateral line (7 in G. crocatus; 7-9 in G. camopiensis). Including the new species, five cichlids and 11 fish species in total are known only from the upper rio Aripuanã, and 15 fish species in total are known only from the rio Aripuanã drainage

    Diversification of Neoaves: integration of molecular sequence data and fossils.2006Ingår i: Biology Letters, ISSN 1744-9561, E-ISSN 1744-957X, Vol. 2, nr 4, s. 543-7Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Patterns of diversification and timing of evolution within Neoaves, which includes almost 95% of all bird species, are virtually unknown. On the other hand, molecular data consistently indicate a Cretaceous origin of many neoavian lineages and the fossil record seems to support an Early Tertiary diversification. Here, we present the first well-resolved molecular phylogeny for Neoaves, together with divergence time estimates calibrated with a large number of stratigraphically and phylogenetically well-documented fossils. Our study defines several well-supported clades within Neoaves. The calibration results suggest that Neoaves, after an initial split from Galloanseres in Mid-Cretaceous, diversified around or soon after the K/T boundary. Our results thus do not contradict palaeontological data and show that there is no solid molecular evidence for an extensive pre-Tertiary radiation of Neoaves.

    A Gondwanan origin of passerine birds supported by DNA sequences of the endemic New Zealand wrens.2002Ingår i: Proceedings of the Royal Society of London. Biological Sciences, ISSN 0962-8452, E-ISSN 1471-2954, Vol. 269, nr 1488, s. 235-41Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Zoogeographic, palaeontological and biochemical data support a Southern Hemisphere origin for passerine birds, while accumulating molecular data suggest that most extant avian orders originated in the mid-Late Cretaceous. We obtained DNA sequence data from the nuclear c-myc and RAG-1 genes of the major passerine groups and here we demonstrate that the endemic New Zealand wrens (Acanthisittidae) are the sister taxon to all other extant passerines, supporting a Gondwanan origin and early radiation of passerines. We propose that (i) the acanthisittids were isolated when New Zealand separated from Gondwana (ca. 82-85 Myr ago), (ii) suboscines, in turn, were derived from an ancestral lineage that inhabited western Gondwana, and (iii) the ancestors of the oscines (songbirds) were subsequently isolated by the separation of Australia from Antarctica. The later spread of passerines into the Northern Hemisphere reflects the northward migration of these former Gondwanan elements.

    Evolution, biogeography, and patterns of diversification in passerine birds2003Ingår i: Journal of Avian Biology, ISSN 0908-8857, E-ISSN 1600-048X, Vol. 34, nr 1, s. 3-15Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper summarizes and discusses the many new insights into passerine evolution gained from an increased general interest in avian evolution among biologists, and particularly from the extensive use of DNA sequence data in phylogenetic reconstruction. The sister group relationship between the New Zealand rifleman and all other passerines, indicates the importance of the former southern supercontinent Gondwana in the earliest evolution of this group. Following the break-up of Gondwana, the ancestors of other major passerine groups became isolated in Australia (oscines), South America (New World suboscines), and possibly, the then connected Kerguelen Plateau/India/Madagascar tectonic plates (Old World suboscines). The oscines underwent a significant radiation in the Australo-Papuan region and only a few oscine lineages have spread further than to the nearby Southeast Asia. A remarkable exception is the ancestor to the vast Passerida radiation, which now comprises 35% of all bird species. This group obviously benefitted greatly from the increased diversity in plant seed size and morphology during the Tertiary. The lyrebirds (and possibly scrub-birds) constitute the sister group to all other oscines, which renders “Corvida” (sensu Sibley and Ahlquist 1990) paraphyletic. Sequence data suggests that Passerida, the other clade of oscines postulated based on the results of DNA–DNA hybridizations, is monophyletic, and that the rockfowl and rock-jumpers are the most basal members of this clade. The suboscines in the Old World (Eurylamides) and the New World (Tyrannides), respectively, are sister groups. A provisional, working classification of the passerines is presented based on the increased understanding of the major patterns of passerine evolution.

    Inter-generic relationships of the crows, jays, magpies and allied groups (Aves: Corvidae) based on nucleotide sequence data2005Ingår i: Journal of Avian Biology, ISSN 0908-8857, E-ISSN 1600-048X, Vol. 36, nr 3, s. 222-234Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Phylogenetic relationships were studied based on DNA sequences obtained from all recognized genera of the family Corvidae sensu stricto. The aligned data set consists 2589 bp obtained from one mitochondrial and two nuclear genes. Maximum parsimony, maximum-likelihood, and Bayesian inference analyses were used to estimate phylogenetic relationships. The analyses were done for each gene separately, as well as for all genes combined. An analysis of a taxonomically expanded data set of cytochrome b sequences was performed in order to infer the phylogenetic positions of six genera for which nuclear genes could not be obtained. Monophyly of the Corvidae is supported by all analyses, as well as by the occurrence of a deletion of 16 bp in the β-fibrinogen intron in all ingroup taxa. Temnurus and Pyrrhocorax are placed as the sister group to all other corvids, while Cissa and Urocissa appear as the next clade inside them. Further up in the tree, two larger and well-supported clades of genera were recovered by the analyses. One has an entirely New World distribution (the New World jays), while the other includes mostly Eurasian (and one African) taxa. Outside these two major clades are Cyanopica and Perisoreus whose phylogenetic positions could not be determined by the present data. A biogeographic analysis of our data suggests that the Corvidae underwent an initial radiation in Southeast Asia. This is consistent with the observation that almost all basal clades in the phylogenetic tree consist of species adapted to tropical and subtropical forest habitats.

    Phylogeny of Passerida (Aves: Passeriformes) based on nuclear and mitochondrial sequence data.2003Ingår i: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 29, nr 1, s. 126-38Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Passerida is a monophyletic group of oscine passerines that includes almost 3500 species (about 36%) of all bird species in the world. The current understanding of higher-level relationships within Passerida is based on DNA-DNA hybridizations [C.G. Sibley, J.E. Ahlquist, Phylogeny and Classification of Birds, 1990, Yale University Press, New Haven, CT]. Our results are based on analyses of 3130 aligned nucleotide sequence data obtained from 48 ingroup and 13 outgroup genera. Three nuclear genes were sequenced: c-myc (498-510 bp), RAG-1 (930 bp), and myoglobin (693-722 bp), as well one mitochondrial gene; cytochrome b (879 bp). The data were analysed by parsimony, maximum-likelihood, and Bayesian inference. The African rockfowl and rockjumper are found to constitute the deepest branch within Passerida, but relationships among the other taxa are poorly resolved--only four major clades receive statistical support. One clade corresponds to Passeroidea of [C.G. Sibley, B.L. Monroe, Distribution and Taxonomy of Birds of the World, 1990, Yale University Press, New Haven, CT] and includes, e.g., flowerpeckers, sunbirds, accentors, weavers, estrilds, wagtails, finches, and sparrows. Starlings, mockingbirds, thrushes, Old World flycatchers, and dippers also group together in a clade corresponding to Muscicapoidea of Sibley and Monroe [op. cit.]. Monophyly of their Sylvioidea could not be corroborated--these taxa falls either into a clade with wrens, gnatcatchers, and nuthatches, or one with, e.g., warblers, bulbuls, babblers, and white-eyes. The tits, penduline tits, and waxwings belong to Passerida but have no close relatives among the taxa studied herein.
