    Abstract [en]

    Four known and one new species of Onchium are described from bottom sediments collected in Skagerrak off the west coast of Sweden. The following known species are redescribed: Onchium ocellatum Cobb, 1920, O. metocellatum Wieser, 1956, O. parocellatum (Allgén, 1940) and O. robustum Gerlach, 1965. Onchium longispiculum sp. n. is characterised by the 1.34–1.77 mm long body, anterior body end without cephalic capsule, anteriormost somatic sensilla located posterior to onchiostyle base, ocelli absent, excretory pore located at basis of lips, onchiostyle uniformly cylindrical, alveolar sup- plements indistinct, tubular supplements absent, spicules arcuate and 44–65 μm long. The new species has a unique set of characters (absence of developed ocelli and very long somewhat asymmetrical spicules) separating it from all other known species of the genus Onchium. The following nomenclatorial changes are proposed: O. conicaudatum (Allgén, 1935) is considered a junior synonym of O. metocellatum; O. conicaudatum apud Wieser, 1951 is considered a synonym of O. minutum Kito, 1981. The diagnosis of the genus Onchium is emended and a tabular compendium and dichotomous iden- tification key to species of the genus Onchium are provided.

    The nomenclatural status of new nematode nomina proposed in 1993 in the doctoral thesis of Christian Bussau, entitled Taxonomische und ökologische Untersuchungen an Nematoden des Peru-Beckens (Nematoda)2020In: Bionomina: International Journal of Biological Nomenclature and Terminology, ISSN 1179-7649, E-ISSN 1179-7657, Vol. 19, p. 86-99Article in journal (Refereed)
    Abstract [en]

    In his doctoral thesis, Christian Bussau published 110 new nematode nomina, including 97 nomina of new species, 11 of new genera and two of new subfamilies. The nomenclatural availability of these nomina has not been generally accepted and is evaluated here. It is determined that the doctoral thesis published by Bussau (1993) satisfies the criteria of publication outlined in Article 8 of the Code, and that all nomenclatural acts published in it satisfy the criteria of availability outlined in Articles 11 and 13 of the Code. The correct authority for all nomina first published in Bussau (1993) is ‘Bussau, 1993’, and not ‘Bussau, 1995’ or ‘Bussau & Vopel, 1999’. All nomenclatural acts published in Bussau (1995) and Bussau & Vopel (1999) are junior objective synonyms of acts published in Bussau (1993), except for Bathynox Bussau & Vopel, 1999. Nox Bussau, 1993 is a junior homonym of Nox Nalbant, 1986, and was provided the available new replacement nomen Bathynox Bussau & Vopel, 1999. The correct authority of Bathynox clavata is ‘(Bussau, 1993)’.

    Abstract [en]

    A new genus Neocamacolaimus gen. n., with one new species N. parasiticus gen. n., sp. n. is described from the benthic polychaete Sphaerosyllis cf. hystrix collected in the Skagerrak off the west coast of Sweden. Neocamacolaimus gen. n. is placed in the family Camacolaimidae and is particularly characterised by having annulated cuticle with lateral alae; seti- form cephalic sensilla located at level with amphids; amphidial fovea ventrally spiral; buccal cavity without armament; pharynx muscular; nerve ring located at base of pharynx; male reproductive system diorchic with outstretched testes; spic- ules weakly arcuate with straight manubrium; gubernaculum absent; alveolar supplements located in the pharyngeal re- gion; tubular supplements absent; tail conoid; caudal glands and spinneret present. Juveniles of this genus are particularly characterised by their parasitic lifestyle and the following unique morphological features: lips form a dorso-ventrally elon- gated perioral disc with internal sclerotizations: one midventral and two dorsosublateral (right and left); cephalic sensilla setiform, subventral sensilla are noticeably longer than the subdorsal ones; intestine extends posterior to rectum and anal opening, forming a post-anal pouch.

    Abstract [en]

    The new genus and species Yeatesinia barbata gen. n., sp. n. is described from a sand dune habitat in New Zealand. The new genus is characterised by a body length of 299-357 μm in females and 304-361 μm in males, lip region rounded dorso-ventrally, broad laterally, dorsally inclined, lateral sides of lip region with two large, horn-like, projections, each bearing one seta at its base, each amphid surrounded by three setiform sensilla, oral opening a broad transverse slit located on the dorsal body surface, and different structure of cuticle in the dorsal and ventral body sectors. This combination of unique morphological characters clearly separates the new genus from all other members of the Plectidae. The phylogenetic affinities of Yeatesinia gen. n. and its relationships to other genera of the family Plectidae are discussed.

    Molecular phylogeny of Lymantriinae (Lepidoptera, Noctuoidea, Erebidae) inferred from eight gene regions2015In: Cladistics, ISSN 0748-3007, E-ISSN 1096-0031, Vol. 31, no 6, p. 579-592Article in journal (Refereed)
    Abstract [en]

    To understand the evolutionary history of Lymantriinae and test the present higher-level classification, we performed the first broad-scale molecular phylogenetic analysis of the subfamily, based on 154 exemplars representing all recognized tribes and drawn from all major biogeographical regions. We used two mitochondrial genes (cytochrome c oxidase subunit I and 16S ribosomal RNA) and six nuclear genes (elongation factor-1α, carbamoylphosphate synthase domain protein, ribosomal protein S5, cytosolic malate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase and wingless). Data matrices (in total 5424 bp) were analysed by parsimony and model-based evolutionary methods (maximum likelihood and Bayesian inference). Based on the results of the analyses, we present a new phylogenetic classification for Lymantriinae composed of seven well-supported tribes, two of which are proposed here as new: Arctornithini, Leucomini, Lymantriini, Orgyiini, Nygmiini, Daplasini trib. nov. and Locharnini trib. nov. We discuss the internal structure of each of these tribes and address some of the more complex problems with the genus-level classification, particularly within Orgyiini and Nygmiini.

    Responses of soil microbiota and nematodes to application of organic and inorganic fertilizers in grassland columns2020In: Biology and Fertility of Soils, ISSN 0178-2762, E-ISSN 1432-0789, Vol. 56, p. 647-662Article in journal (Refereed)
    Abstract [en]

    Enhancing the role of the soil microbiota in plant phosphorus (P) and sulfur (S) supply through application of organic fertilizer could reduce dependencies on non-sustainable synthetic fertilizers. To compare the effects of organic/inorganic fertilizers on the soil microbiota, soil columns with Lolium perenne (ryegrass) were set up in a greenhouse and amended with an inorganic fertilizer, cattle slurry (organic), or urea (P- and S-free control). Ryegrass rhizosphere of the slurry treatment had significantly higher abundances of bacterial feeding nematodes, mycorrhizal colonization, cultivable heterotrophic bacteria, phosphonate- and sulfonate-utilizing bacteria, arylsulfatase activity, available P, and Variovorax asfA gene copies compared to the inorganic and urea treatments. Phosphomonoesterase activities, and gene abundances involved in organic P and S transformations (phoD, phoC, Burkholderia, and Polaromonas asfA) were similar in all treatments. Grass dry matter yield and shoot uptake of N, P, and S were significantly higher in the inorganic treatment compared to the urea and slurry treatments. Community compositions differed significantly between the three fertilizer treatments and included the bacterial, alkaline phosphomonoesterase- producing bacterial, fungal, AM fungal, and nematode communities. Bacteriodetes were found in higher relative abundance in the organic treatment, while Acidobacteria were more abundant in the urea and inorganic fertilizer treatments. These com- munity shifts correlated significantly with grass dry matter yield, uptake of N, P, and S, mycorrhizal colonization, enzyme activities, abundances of bacteria, and bacterial feeding nematodes. We concluded that organic fertilization promoted soil microbes and nematodes which have the potential to support sustainable plant growth, provided that the overall nutrient requirements are met.

    Systematic relationships and biogeography of the tracheophone suboscines (Aves: Passeriformes).2002In: Molecular Phylogenetics and Evolution, ISSN 1055-7903, E-ISSN 1095-9513, Vol. 23, no 3, p. 499-512Article in journal (Refereed)
    Abstract [en]

    Based on their highly specialized "tracheophone" syrinx, the avian families Furnariidae (ovenbirds), Dendrocolaptidae (woodcreepers), Formicariidae (ground antbirds), Thamnophilidae (typical antbirds), Rhinocryptidae (tapaculos), and Conopophagidae (gnateaters) have long been recognized to constitute a monophyletic group of suboscine passerines. However, the monophyly of these families have been contested and their interrelationships are poorly understood, and this constrains the possibilities for interpreting adaptive tendencies in this very diverse group. In this study we present a higher-level phylogeny and classification for the tracheophone birds based on phylogenetic analyses of sequence data obtained from 32 ingroup taxa. Both mitochondrial (cytochrome b) and nuclear genes (c-myc, RAG-1, and myoglobin) have been sequenced, and more than 3000 bp were subjected to parsimony and maximum-likelihood analyses. The phylogenetic signals in the mitochondrial and nuclear genes were compared and found to be very similar. The results from the analysis of the combined dataset (all genes, but with transitions at third codon positions in the cytochrome b excluded) partly corroborate previous phylogenetic hypotheses, but several novel arrangements were also suggested. Especially interesting is the result that the genus Melanopareia represents a basal branch within the tracheophone group, positioned in the phylogenetic tree well away from the typical tapaculos with which it has been supposed to group. Other novel results include the observation that the ground antbirds are paraphyletic and that Sclerurus is the sister taxon to an ovenbird-woodcreeper clade. Patterns of generic richness within each clade suggest that the early differentiation of feeble-winged forest groups took place south of the Amazon Basin, while the more recent diversification was near the equator and (in tapaculos and ovenbirds) in the south of the continent.

    Phylogeny of major lineages of suboscines (Passeriformes) analysed by nuclear DNA sequence data2001In: Journal of Avian Biology, ISSN 0908-8857, E-ISSN 1600-048X, Vol. 32, no 1, p. 15-25Article in journal (Refereed)
    Abstract [en]

    Phylogenetic relationships among major groups of passeriform birds were studied by analyses of nucleotide sequence data from two nuclear genes, c-myc and RAG-1. The results corroborated both the monophyly of the order Passeriformes, and the major dichotomy into oscine and suboscine passerines previously suggested based on syringeal morphology and DNA-DNA hybridizations. The representatives of the Old World suboscines (families Eurylaimidae, Philepittidae and Pittidae) formed a monophyletic clade. The New World suboscines clustered into two clades. The first contained Conopophaga (Conopophagidae), Furnarius (Furnariidae), Lepidocolaptes (Dendrocolaptidae), Thamnophilus (Formicariidae), and Rhinocrypta (Rhinocryptidae). Previously, the monophyly of this group has been inferred from their possession of a unique, "tracheophone" syrinx, and from DNA-DNA hybridisation data. The second clade of New World suboscines includes Gubernetes and Muscivora (Tyrannidae), Phytotoma (Phytotomidae), Tityra (Cotingidae) and Pipra (Pipridae). This group of families have been considered monophyletic based on morphology (although ambiguously) and DNA-DNA hybridisation. The sister group relationship of Tityra and Phytotoma supports the previously supposed cotingid affinity of Phytotoma. Nuclear DNA data also unambiguously group the lyrebirds Menura with the oscines. The presented results from the analysis of nuclear DNA agree well with morphology and DNA-DNA hybridisation data. The precise age of the divergences studied herein are unknown but based on interpretations of the fossil record of passerine birds many of them might date back to the early Tertiary. The agreement between data from the nuclear DNA and other sources, along with the fact that neither of the studied genes showed sign of saturation, indicate the great potential of these two nuclear genes to resolve very old divergences in birds.

    Sexual conflict and intrasexual polymorphism promote assortative mating and halt population differentiation2019In: Proceedings of the Royal Society of London. Biological Sciences, ISSN 0962-8452, E-ISSN 1471-2954, Vol. 286, p. 1-8Article in journal (Refereed)
    Abstract [en]

    Sexual conflict is thought to be an important evolutionary force in drivingphenotypic diversification, population divergence, and speciation. However,empirical evidence is inconsistent with the generality that sexual conflictenhances population divergence. Here, we demonstrate an alternativeevolutionary outcome in which sexual conflict plays a conservative role inmaintaining male and female polymorphisms locally, rather than promotingpopulation divergence. In diving beetles, female polymorphisms haveevolved in response to male mating harassment and sexual conflict. We presentthe first empirical evidence that this female polymorphism is associatedwith (i) two distinct and sympatric male morphological mating clusters(morphs) and (ii) assortative mating between male and female morphs.Changes in mating traits in one sex led to a predictable change in the othersex which leads to predictable within-population evolutionary dynamics inmale and female morph frequencies. Our results reveal that sexual conflictcan lead to assortative mating between male offence and female defencetraits, if a stable male and female mating polymorphisms are maintained.Stable male and female mating polymorphisms are an alternative outcometo an accelerating coevolutionary arms race driven by sexual conflict. Suchstable polymorphisms challenge the common view of sexual conflict as anengine of rapid speciation via exaggerated coevolution between sexes.

    The century old taxonomic confusion surrounding Wiedemannia zetterstedti Fallén and related species is resolved (Diptera: Empididae): Revision of the W. zetterstedti group2022In: Insects, E-ISSN 2075-4450, Vol. 13, no 5, p. 460-460Article in journal (Refereed)
    Abstract [en]

    The Wiedemannia zetterstedti species group is revised after examination of all available type specimens and includes one new species (W. ulrichi Ivković & Sinclair sp. nov.) and four redescribed species (W. czernyi (Bezzi), W. longipennis (Mik) stat. rev., W. rufipes (Oldenberg) stat. rev. and W. zetterstedti (Fallén)). The following new synonyms are proposed: W. (Roederella) ouedorum Vaillant, 1952 = W. czernyi (Bezzi, 1905); Paramesia riparia Robert, 1836 = W. zetterstedti (Fallén, 1826). Lectotypes are designated for the following species/subspecies: Atalanta hirtiloba Speiser, Brachystoma escheri Zetterstedt, Clinocera czernyi Bezzi, Clinocera longipennis Mik, Paramesia riparia Robert, and Roederia czernyi rufipes Oldenberg. In addition to morphological evidence, molecular species concepts were investigated using a molecular phylogenetic divergence-based species delimitation (bPTP) and results confirmed the morphological conclusions. A key to species is presented and geographic distributions are mapped.

    Molecular phylogenetics and biogeography provide insights into the subgeneric classification of Wiedemannia Zetterstedt (Diptera: Empididae: Clinocerinae)2019In: Systematic Entomology, ISSN 0307-6970, E-ISSN 1365-3113, Vol. 44, p. 559-570Article in journal (Refereed)
    Abstract [en]

    The subgenera of Wiedemannia are poorly defined and, as such, most recently described species are not assigned to a subgenus or have been assigned to a subgenus without explanation. In this study we perform a molecular phylogenetic analysis to elucidate relationships within the genus Wiedemannia. We sequenced two mitochondrial (cytochrome oxidase c subunit I and cytochrome β) and two nuclear (carbomoylphosphate synthase domain of rudimentary and elongation factor‐1α) gene fragments to reconstruct phylogenetic relationships among the subgenera ChamaedipsiaEucelidiaPhilolutraPseudowiedemanniaRoederella and Wiedemannia (s.s.) using both Bayesian inference and maximum likelihood approaches. The genus was found to be monophyletic, but most of the subgenera were not. We propose eliminating the present subgeneric division altogether. Molecular dating using a log‐normal clock model and calibration with fossil species indicated that Wiedemannia diversified about 48 Ma, while there was still land connectivity between Europe and Asia with North America. Wiedemannia has a near‐worldwide distribution apart from the Australasian and Neotropical regions and Antarctica, with greatest species richness in the western Palaearctic, especially the Mediterranean region. Molecular phylogenetics support more recent morphological studies. The subgenera of Wiedemannia are invalid and rejected. Biogeographical data suggest potential hotspots, and the current distribution is discussed.
