New observations of the enigmatic West African Cellana limpet (Mollusca: Gastropoda: Nacellidae)
(Peer reviewed; Journal article, 2016-07-25)Background: Identification of limpets is often hampered by highly variable within-species shell morphologies and colour patterns. Since pre-Linnean times this has produced complex taxonomies with confusing nomenclatorial ... -
The black-legged kittiwake preen gland—an overlooked organ for depuration of fat-soluble contaminants?
(Peer reviewed; Journal article, 2016-08-18)Most birds preen their feathers with an oily excrete from the uropygial (preen) gland. This oily excrete contains persistent organic pollutants (POPs), which make the preen gland a potential route of depuration of POPs in ... -
Genomic mining of phylogenetically informative nuclear markers in bark and ambrosia beetles
(Peer reviewed; Journal article, 2016-09-26)Deep level insect relationships are generally difficult to resolve, especially within taxa of the most diverse and species rich holometabolous orders. In beetles, the major diversity occurs in the Phytophaga, including ... -
Hybridization between the locally endangered Rosa spinosissima and Rosa mollis results in the pentaploid Rosa × sabinii in Western Norway
(Peer reviewed; Journal article, 2016-12)Rosa spinosissima is an endangered species in Norway, found only within a limited area on the southwestern coast. Presumed hybrid forms between R. spinosissima and rose species within R. sect. Caninae have been recorded ... -
Identification of the polyp stage of three leptomedusa species using DNA barcoding
(Peer reviewed; Journal article, 2017)DNA sequence data of hydromedusae and hydroids collected in the fjords near Bergen, Norway, permitted to connect three leptomedusae to three thecate hydroids with hitherto unknown life cycles. For all three species pairs, ... -
Ancient diversity of afrotropical Microborus: three endemic species - not one widespread
(Peer reviewed; Journal article, 2017)The primarily Neotropical genus Microborus Blandford is represented with three species in Africa and Madagascar. The previously recorded species from this region, M. boops Blandford, is a Neotropical species restricted to ... -
Jellyfish summer distribution, diversity and impact on fish farms in a Nordic fjord
(Peer reviewed; Journal article, 2017)Jellyfish can cause high mortality of farmed fish and hence significant economic losses for the aquaculture industry. Despite their socio-economic importance, distribution and diversity data on gelatinous plankton are ... -
Late Pleistocene songbirds of Liang Bua (Flores, Indonesia); the first fossil passerine fauna described from Wallacea
(Peer reviewed; Journal article, 2017-08-17)Background: Passerines (Aves: Passeriformes) dominate modern terrestrial bird communities yet their fossil record is limited. Liang Bua is a large cave on the Indonesian island of Flores that preserves Late Pleistocene–Holocene ... -
Taxonomy and phylogeny of the family Fuscideaceae (Umbilicariales, Ascomycota) with special emphasis on Fuscidea
(Doctoral thesis, 2017-10-06)Introduction: For several decades, the taxonomic position of the lichen family Fuscideaceae and its associated genera, including the type genus Fuscidea V. Wirth & Vĕzda, has been debated. Amongst the species of Fuscidea, ... -
The taxonomy of the lichen Fuscidea cyathoides (Fuscideaceae, Umbilicariomycetidae, Ascomycota) in Europe
(Peer reviewed; Journal article, 2017-11)Based on morphometric and molecular methods, the taxonomy of the infraspecific taxa of Fuscidea cyathoides (Ach.) V. Wirth & Vězda, var. corticola (Fr.) Kalb and var. sorediata (H. Magn.) Poelt, has been assessed. No formal ... -
Abundance, distribution and diversity of gelatinous predators along the northern Mid-Atlantic Ridge: A comparison of different sampling methodologies
(Peer reviewed; Journal article, 2017-11-02)The diversity and distribution of gelatinous zooplankton were investigated along the northern Mid-Atlantic Ridge (MAR) from June to August 2004.Here, we present results from macrozooplankton trawl sampling, as well as ... -
A pollen analytical study of faeces from wiegon, Anas penelope . A case study
(Journal article, 2018)Pollen analysis of faeces from bird (also mammals (King 1977)) gives important additional information about attractive and nutrient rich pla nt fodder hardly traceable using macro analysis or by field observation (e.g. ... -
New molecular markers resolve the phylogenetic position of the enigmatic wood-boring weevils Platypodinae (Coleoptera: Curculionidae)
(Peer reviewed; Journal article, 2018)The precise phylogenetic position of the weevil subfamily Platypodinae continues to be one of the more contentious issues in weevil systematics. Morphological features of adult beetles and similar ecological adaptations ... -
