Background Microhabitat changes are thought to be among the main drivers of diversification. However, this conclusion is mostly based on studies on vertebrates. Here, we investigate the influence of ...

Background A median, segmented, annelid nerve cord has repeatedly been compared to the arthropod and vertebrate nerve cords and became the most used textbook representation of the annelid nervous system. ...

Despite the similar function of all sperm cells – to fertilise the egg – there is extraordinary diversity in sperm shape and length across taxa. This thesis aims to improve our understanding of how this diversity has ...

Natural history museum collections represent a vast source of ancient and historical DNA samples from extinct taxa that can be utilized by high-throughput sequencing tools to reveal novel genetic and phylogenetic information ...

One hundred and seventy-three years ago, the last two Great Auks, Pinguinus impennis, ever reliably seen were killed. Their internal organs can be found in the collections of the Natural History Museum of Denmark, but the ...

Gene expression changes potentially play an important role in adaptive evolution under human‐induced selection pressures, but this has been challenging to demonstrate in natural populations. Fishing exhibits strong selection ...

Chikanda is a traditional dish made with wild-harvested ground orchid tubers belonging to three orchidioid genera, Disa, Satyrium and Habenaria, all of which are CITES appendix II-listed. Identification of collected orchid ...

High tropical mountains harbour remarkable and fragmented biodiversity thought to a large degree to have been shaped by multiple dispersals of cold-adapted lineages from remote areas. Few dated phylogenetic/phylogeographic ...

Telomere length is related to aging in many eukaryotes and the rate of telomere attrition has been suggested to reflect individual genetic quality. Telomere length could thus have implications for mate choice. We investigated ...

Previous studies based on single mitochondrial markers have shown that the common raven (Corvus corax) consists of two highly diverged lineages that are hypothesised to have undergone speciation reversal upon secondary ...

Complete mitochondrial genomes of five syllids (Streptosyllis sp., Eusyllis blomstrandi, Myrianida brachycephala, Typosyllis antoni and Typosyllis sp.) have been obtained using Illumina sequencing. Together with two previous ...

Abstract.—Phylogenomic studies have improved understanding of deep metazoan phylogeny and show promise for resolving incongruences among analyses based on limited numbers of loci. One region of the animal tree that has ...

Sperm morphological traits are highly variable among species and are commonly thought to evolve by post-copulatory sexual selection. However, little is known about the evolutionary dynamics of sperm morphology, and whether ...

Background Postzygotic isolation in the form of reduced viability and/or fertility of hybrids may help maintain species boundaries in the face of interspecific gene flow. Past hybridization events between ...

Background The population size of Atlantic walruses (Odobenus rosmarus rosmarus) is depleted relative to historical abundance levels. In Svalbard, centuries of over-exploitation brought the walrus herds to ...

Human wellbeing and food security in a changing climate depend on productive and sustainable agriculture. For this, policies based on analyses and research results are vital to establish conservation priorities of natural ...

The easier access to increasingly powerful computational approaches and tools in the field of distribution modelling, has contributed to a proliferation of data, applications, practitioners, guidelines, and novel theoretical ...

The study of the family Encyrtidae at the Natural History Museum of Oslo continues. Sixteen species are reported for the first time from Norway in this revision, bringing the total number of Norwegian encyrtids up to 123. ...

The two aphid species Panaphis juglandis (Goeze, 1778) and Chromaphis juglandicola (Kaltenbach, 1843) were recorded on leaves of common walnut (Juglans regia L.) in June and July 2014 in the Botanical garden at Tøyen, Oslo. ...

Predictive characterizationPredictive characterization methods use ecogeographical and climatic data derived from the specific location of a collecting or observation site, to predict characteristics of accessions and ...

Background: Heligmosomoides polygyrus is a widespread gastro-intestinal nematode infecting wild Apodemus (wood mice) throughout Europe. Using molecular and morphological evidence, we review the status of Heligmosomoides ...

Abundant new ichthyosaur material has recently been documented in the Slottsmøya Member of the Agardhfjellet Formation from the Svalbard archipelago of Norway. Here we describe a partial skeleton of a new taxon, Janusaurus ...

The workshop-hackathon was convened by the Global Biodiversity Information Facility (GBIF) at its secretariat in Copenhagen over 22-24 May 2013 with additional support from several projects (RCN4GSC, EAGER, VertNet, BiSciCol, ...

The family Ichneumonidae represents a very species-rich family of parasitoid Hymenoptera. In Norway, 1583 different Ichneumonid species have been reported so far. The present survey gives distributional records for 98 ...

Field station lists and maps Original station descriptions and maps from a sampling project: collecting marine benthic invertebrates during annual summer period cruises 1950-1953 with research vessel R/V “G.M. Dannevig”. ...
