    Sabertoothed carnivores and the killing of large prey2011Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 6, nr 10, s. e24971-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sabre-like canines clearly have the potential to inflict grievous wounds leading to massive blood loss and rapid death. Hypotheses concerning sabretooth killing modes include attack to soft parts such as the belly or throat, where biting deep is essential to generate strikes reaching major blood vessels. Sabretoothed carnivorans are widely interpreted as hunters of larger and more powerful prey than that of their present-day nonsabretoothed relatives. However, the precise functional advantage of the sabretooth bite, particularly in relation to prey size, is unknown. Here, we present a new point-to-point bite model and show that, for sabretooths, depth of the killing bite decreases dramatically with increasing prey size. The extended gape of sabretooths only results in considerable increase in bite depth when biting into prey with a radius of less than ~10 cm. For sabretooths, this size-reversed functional advantage suggests predation on species within a similar size range to those attacked by present-day carnivorans, rather than “megaherbivores” as previously believed. The development of the sabretooth condition appears to represent a shift in function and killing behaviour, rather than one in predator-prey relations. Furthermore, our results demonstrate how sabretoothed carnivorans are likely to have evolved along a functionally continuous trajectory: beginning as an extension of a jaw-powered killing bite, as adopted by present-day pantherine cats, followed by neck-powered biting and thereafter shifting to neck-powered shear-biting. We anticipate this new insight to be a starting point for detailed study of the evolution of pathways that encompass extreme specialisation, for example, understanding how neck-powered biting shifts into shear-biting and its significance for predator-prey interactions. We also expect that our model for point-to-point biting and bite depth estimations will yield new insights into the behaviours of a broad range of extinct predators including therocephalians (gorgonopsian + cynodont, sabretoothed mammal-like reptiles), sauropterygians (marine reptiles) and theropod dinosaurs.

    Carnivora from the Late Miocene of Lantian, China2005Ingår i: Vertebrata PalAsiatica, Vol. 43, s. 256-271Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sediments of the Bahe and Lantian formations, Lantian area, Shaanxi Province, China, have produced a large number of mammalian fossils. This Late Miocene sequence provides evidence for a period of major changes in the physical environment of the region. The carnivoran fossils are described and analyzed herein. The following species are present: lctitherium viverrinum, Hyaenictitherium cf . H. wongii and Adcrocuta eximia ( Hyaenidae) , cf. Metailurus major and cf. Metailurus parvulus ( Felidae) . Although a difference in the composition of the carnivoran fauna is noted towards the boundary between the Bahe Formation (lower) and Lantian Formation (upper), the cause of this is yet to be determined.

    Wide distributions and cryptic diversity within a Microstomum (Platyhelminthes) species complex2018Ingår i: Zoologica Scripta, ISSN 0300-3256, E-ISSN 1463-6409, Vol. 47, s. 486-498Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Microstomum lineare is a common species of fresh and brackish waters found world-wide. Three genes (18S, CO1 and ITS) were sequenced from specimens of M. lineare collected from four countries, and the levels of cryptic diversity and genetic structuring were assessed. Results showed M. lineare has very wide haplotype distributions suggesting higher than expected dispersal capabilities. In addition, three new species were described on the basis of molecular taxonomy: Microstomum artoisi sp. nov., Microstomum tchaikovskyi sp. nov. and Microstomum zicklerorum sp. nov.

    Phylogeny of penduline tits inferred from mitochondrial and microsatellite genotyping2017Ingår i: Journal of Avian Biology, ISSN 0908-8857, E-ISSN 1600-048X, Vol. 48, nr 7, s. 932-940Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Penduline tits (Remiz spp.) are renowned for their diverse mating and parenting strategies, and are a well-studied system by behavioural ecologists. However, the phylogenetic relationships and species delimitations within this genus are poorly understood. Here, we investigate phylogenetic relationships within the genus Remiz by examining the genetic variation in the mitochondrial cytochrome-b gene of 64 individuals and in ten autosomal microsatellite markers from 44 individuals. The taxon sampling includes individuals from all currently recognized species (R. pendulinus, R. macronyx, R. coronatus, and R. consobrinus) and most subspecies in the Palearctic region. We showed that R. coronatus and R. consobrinus are genetically well differentiated and constitute independent evolutionary lineages, separated from each other and from R. pendulinus/macronyx. However, we found no evidence for significant differentiation among R. pendulinus/macronyx individuals in mtDNA haplotypes and only marginal differences between R. pendulinus and R. macronyx in microsatellite markers. Hence, based on present data our recommendation is to treat R. pendulinus and R. macronyx as conspecific and R. coronatus and R. consobrinus as separate species.

    Chancelloriids of the Cambrian Burgess Shale2015Ingår i: Palaeontologia Electronica, ISSN 1935-3952, E-ISSN 1094-8074, Vol. 18, nr 1, s. 1-67Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The cactus-like chancelloriids from the Middle Cambrian Burgess Shale are revised on the basis of Walcott’s (1920) original collections and new material containing several hundred specimens collected by Royal Ontario Museum field expeditions from 1975 to 2000. Walcott’s interpretation of chancelloriids as sponges was based on a misinterpretation of the dermal coelosclerites as embedded sponge-type spicules, an interpretation that further led to the lumping of three distinct taxa into one species, Chancelloria eros Walcott, 1920. The other two taxa are herein separated from C. eros and described as Allonnia tintinopsis n.sp. and Archiasterella coriacea n.sp., all belonging to the Family Chancelloriidae Walcott, 1920. Chancelloriids were sedentary animals, anchored to shells or lumps of debris in the muddy bottom, or to sponges, or to other chancelloriids. They had a radially symmetrical body and an apical orifice surrounded by a palisade of modified sclerites. Well-preserved integuments in Al. tintinopsis and Ar. coriacea do not show any ostium-like openings. Neither is there any evidence for internal organs, such as a gut. Partly narrowed specimens suggest that the body periodically contracted from the attached end to expel waste material from the body cavity. Chancelloriids were close in organization to cnidarians but shared the character of coelosclerites with the bilaterian halkieriids and siphogonuchitids. The taxon Coeloscleritophora is most likely paraphyletic.

    A merciful death for the “earliest bilaterian,” Vernanimalcula.2012Ingår i: Evolution and Development, ISSN 1520-541x, Vol. 14, nr 5, s. 421-427Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Fossils described as Vernanimalcula guizhouena, from the nearly 600 million-year-old Doushantuo Formation in South China, have been interpreted as the remains of bilaterian animals. As such they would represent the oldest putative record of bilaterian animals in Earth history, and they have been invoked in debate over this formative episode of early animal evolution. However, this interpretation is fallacious. We review the evidential basis of the biological interpretation of Vernanimalcula, concluding that the structures key to animal identity are effects of mineralization that do not represent biological tissues, and, furthermore, that it is not possible to derive its anatomical reconstruction on the basis of the available evidence. There is no evidential basis for interpreting Vernanimalcula as an animal, let alone a bilaterian. The conclusions of evolutionary studies that have relied upon the bilaterian interpretation of Vernanimalcula must be called into question.

    Entomologmötet på Gotland 2017: temaexkursion med fokus på vattenlevande skalbaggar, skinnbaggar och trollsländor i Äskåkersvät.2017Ingår i: Entomologisk Tidskrift, ISSN 0013-886X, Vol. 139, nr 1, s. 39-49Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The yearly Swedish entomology meeting 2017 was organized by the local entomology

    society of Gotland, on the northern part of the Baltic island Gotland near Bunge, 4-6 August.

    One thematic excursion was focused on aquatic insects, especiallly aquatic beetles,

    bugs and dragonflies. A shallow pond, Äskåkersvät, with Characeae in an open grazed

    landscape with high natural values was studied. Äskåkersvät lies just adjacent to the larger

    area around lake Bästeträsk which is the focus of a pilot study evaluating its potential as

    a future national park. The pilot study is undertaken by Gotland County Administrative

    Board, the Swedish Environmental Protection Agency, Region Gotland and the Swedish

    Agency for Marine and Water Management. Here we give an annotated report of the 103

    species found: 69 species of water beetles (out of which 34 were Dytiscidae), 20 species

    of aquatic or semiaquatic bugs (out of which 10 were Corixidae), and 14 species of dragonflies.

    These include Hydrophilus piceus and H. aterrimus redlisted in Sweden (both as

    NT), and Dytiscus latissimus, globally redlisted (VU). We also noted the noble crayfish,

    Astacus astacus (redlisted as CR in Sweden) and the European medicinal leech Hirudo

    medicinalis (redlisted as NT globally). The blue emperor dragonfly (Anax imperator) was

    noted, a species first recorded from Gotland in 2002 and we present a graph on its increase

    and spreading on the island since. The number of species found in spite of a relatively

    modest collecting effort at a suboptimal time when many species may be in pupal stage out

    of water as witnessed by many teneral individuals, indicates a species rich locality with

    high natural value. The stoneworts (Characeae) vegetation certainly contributes to this, for

    instance vouched for by the occurrence of specialists as Haliplus confinis and H. obliquus

    whose larvae feed on stoneworts.

    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.

    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 enigmatic Early Miocene mammal Kelba and its relationship to the order Ptolemaiida2007Ingår i: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 104, s. 5510-5515Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Kelba quadeemae, a fossil mammal from the Early Miocene of East Africa, was originally named on the basis of three isolated upper molars. Kelba has previously been interpreted as a creodont, a pantolestid, an insectivoran, and a hemigaline viverrid. The true affinities of this taxon have remained unclear because of the limited material and its unique morphology relative to other Miocene African mammals. New material of Kelba from several East African Miocene localities, most notably a skull from the Early Miocene locality of Songhor in Western Kenya, permits analysis of the affinities of Kelba and documents the lower dentition of this taxon. Morphological comparison of this new material clearly demonstrates that Kelba is a member of the order Ptolemaiida, a poorly understood group whose fossil record was previously restricted to the Oligocene Fayum deposits of northern Egypt. Phylogenetic analysis supports the monophyly of the Ptolemaiida, including Kelba, and recovers two monophyletic clades within the order. We provide new family names for these groups and an emended diagnosis for the order. The discovery of ptolemaiidans from the Miocene of East Africa is significant because it extends the known temporal range of the order by >10 million years and the geographic range by >3,200 km. Although the higher-level affinities of the Ptolemaiida remain obscure, their unique morphology and distribution through a larger area of Africa (and exclusively Africa) lend support to the idea that Ptolemaiida may have an ancient African origin.

    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.

    The capsule – a newly discovered organic shell structure in the Late Cretaceous belemnite Gonioteuthis from north-west Germany.2011Ingår i: Palaeontology, ISSN 0031-0239, E-ISSN 1475-4983, Palaeontology, Vol. 54, nr 2, s. 397-415Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An unusual, bilaterally symmetrical black structure that embraces the protoconch and the phragmocone and is overlain by a rostrum has been studied in the Santonian– early Campanian (Late Cretaceous) belemnite genus Gonioteuthis from Braunschweig, north-west Germany. The structure is here named the capsule. Energy dispersed spectrometry analyses of the capsule show a co-occurrence of sulphur with zinc, barium, iron, lead and titanium, suggesting their chemical association. The capsule was originally made of organic material that was diagenetically transformed into sulphur-containing matter. The material of the capsule differs from the chitin of the connecting rings in the same specimens. The capsule has a complex morphology: (1) ventral and dorsal wing-like projections that are repeated in a breviconic shape of the alveolus, (2) an aperture with lateral lobes and ventral and dorsal sinuses copied by growth lines and (3) a ventral ridge that fits with the position of the fissure in the rostrum. The alveolus in the most anterior part of the rostrum is crater-like. It is lined with thin, pyritized, laminated material, which appears to be the outermost portion of the capsule attached to the inner surface of the rostrum. A flare along the periphery of the alveolus marks a region where the rostrum was not yet formed, suggesting that the capsule extended beyond the rostrum. Modification of the skeleton in Gonioteuthis comprises a set of supposedly interrelated changes, such as innovation of the organic capsule, partial elimination of the calcareous rostrum and a diminishing of the pro-ostracum, resulting in the appearance of a new type of pro-ostracum that became narrower and shorter and lost the spatula-like shape and gently curved growth lines of a median field that are typical for the majority of Jurassic and Cretaceous belemnites. The partial replacement of a calcareous rostrum with an organic capsule in belemnitellids may have been an adaptive reaction to an unfavourable environmental condition, perhaps related to difficulties in calcium carbonate secretion during the Late Cretaceous that forced animals to reduce carbonate production and to secret an organic capsule around the protoconch and the phragmocone.

    Embryos, polyps and medusae of the early Cambrian scyphozoan Olivooides.2013Ingår i: Proceedings of the Royal Society Biological Sciences Series B, ISSN 0962-8452, Vol. 280, nr 2130071, s. 1-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Early Cambrian organism Olivooides is known from both embryonic and post-embryonic stages and, consequently, it has the potential to yield vital insights into developmental evolution at the time that animal body plans were established. However, this potential can only be realized if the phylogenetic relationships of Olivooides can be constrained. The affinities of Olivooides have proved controversial because of the lack of knowledge of the internal anatomy and the limited range of developmental stages known. Here, we describe rare embryonic specimens in which internal anatomical features are preserved. We also present a fuller sequence of fossilized developmental stages of Olivooides, including associated specimens that we interpret as budding ephyrae ( juvenile medusae), all of which display a clear pentaradial symmetry. Within the framework of a cnidarian interpretation, the new data serve to pinpoint the phylogenetic position of Olivooides to the scyphozoan stem group. Hypotheses about scalidophoran or echinoderm affinities of Olivooides can be rejected.

    Early burst in body size evolution is uncoupled from species diversification in diving beetles (Dytiscidae)2018Ingår i: Molecular Ecology, ISSN 0962-1083, E-ISSN 1365-294X, Vol. 27, nr 4, s. 979-993Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Changes in morphology are often thought to be linked to changes in species diversification,

    which is expected to leave a signal of early burst (EB) in phenotypic traits.

    However, such signal is rarely recovered in empirical phylogenies, even for groups

    with well-known adaptive radiation. Using a comprehensive phylogenetic approach

    in Dytiscidae, which harbours ~4,300 species with as much as 50-fold variation in

    body size among them, we ask whether pattern of species diversification correlates

    with morphological evolution. Additionally, we test whether the large variation in

    body size is linked to habitat preference and whether the latter influences species

    turnover. We found, in sharp contrast to most animal groups, that Dytiscidae body

    size evolution follows an early-burst model with subsequent high phylogenetic conservatism.

    However, we found no evidence for associated shifts in species diversification,

    which point to an uncoupled evolution of morphology and species

    diversification. We recovered the ancestral habitat of Dytiscidae as lentic (standing

    water), with many transitions to lotic habitat (running water) that are concomitant

    to a decrease in body size. Finally, we found no evidence for difference in net diversification

    rates between habitats nor difference in turnover in lentic and lotic species.

    This result, together with recent findings in dragonflies, contrasts with some

    theoretical expectations of the habitat stability hypothesis. Thus, a thorough

    reassessment of the impact of dispersal, gene flow and range size on the speciation

    process is needed to fully encompass the evolutionary consequences of the lentic–

    lotic divide for freshwater fauna.

    A genomic perspective of the pink-headed duck Rhodonessa caryophyllacea suggests a long history of low effective population size2017Ingår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 7, artikel-id 16853Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The first molecular phylogenetic hypothesis for the possibly extinct pink-headed duck Rhodonessa caryophyllacea unambiguously shows that it belongs to the pochard radiation that also includes the genera Aythya and Netta. It is the sister to all modern-day pochards and belongs to a lineage that branched off from the others more than 2.8 million years ago. Rhodonessa caryophyllacea is believed to never have been common in modern time and we show this has probably been the situation for as long as 100,000 years. Our results suggest that their effective population size varied between 15,000 and 25,000 individuals during the last 150,000 years of the Pleistocene. The reasons behind this are largely unknown as very little is known about the life-history and biology of this species. Presumably it is due to factors related to feeding or to breeding, but we may never know this for sure.
