Geographical patterns in phylogenetic diversity of Chinese woody plants and its application for conservation planning
(Journal article; Peer reviewed, 2021)Aim Biodiversity hotspots are widely used as conservation priorities to preserve the tree of life. However, many conservation practices identify biodiversity hotspots without considering phylogenetic diversity (PD), which ... -
Global distribution and evolutionary transitions of angiosperm sexual systems
(Journal article; Peer reviewed, 2021)Angiosperm sexual systems are fundamental to the evolution and distribution of plant diversity, yet spatiotemporal patterns in angiosperm sexual systems and their drivers remain poorly known. Using data on sexual systems ... -
Global gap-analysis of amphipod barcode library
(Journal article; Peer reviewed, 2021)In the age of global climate change and biodiversity loss there is an urgent need to provide effective and robust tools for diversity monitoring. One of the promising techniques for species identification is the use of DNA ... -
Global patterns of species richness of the holarctic alpine herb Saxifraga: The role of temperature and habitat heterogeneity
(Journal article; Peer reviewed, 2022)The effects of contemporary climate, habitat heterogeneity and long-term climate change on species richness are well studied for woody plants in forest ecosystems, but poorly understood for herbaceous plants, especially ... -
Globally distributed Xyleborus species reveal recurrent intercontinental dispersal in a landscape of ancient worldwide distributions Phylogenetics and phylogeography
(Peer reviewed; Journal article, 2016-02-15)Background: Invasive species can have devastating effects on native ecosystems and therefore impose a significant threat to human welfare. The introduction rate of invasive species has accelerated dramatically in recent ... -
Helmutneris vadum, a new species of Lumbrineridae (Annelida) from Lizard Island, Great Barrier Reef, Australia
(Journal article; Peer reviewed, 2020)A new species of Lumbrineridae, Helmutneris vadum n. sp., is described from shallow waters near Lizard Island, Great Barrier Reef, Queensland, Australia. The new species differs from two other known species of Helmutneris ... -
Hiding in plain sight—Euplokamis dunlapae (Ctenophora) in Norwegian waters
(Journal article; Peer reviewed, 2021)Cydippid ctenophores of genus Euplokamis have been rarely reported from the north-east Atlantic in the scientific literature. The conspicuous lack of previous records is likely attributable to methodological constraints ... -
High Diversity of Mites (Acari: Oribatida, Mesostigmata) Supports the High Conservation Value of a Broadleaf Forest in Eastern Norway
(Journal article; Peer reviewed, 2021)Broadleaf forests are critical habitats for biodiversity and this biodiversity is in turn essential for their proper functioning. Mites (Acari) are a numerous and functionally essential component of these forests. We report ... -
High genetic diversity of common toad (Bufo bufo) populations under strong natural fragmentation on a Northern archipelago
(Peer reviewed; Journal article, 2016-03)The last decades have shown a surge in studies focusing on the interplay between fragmented habitats, genetic variation, and conservation. In the present study, we consider the case of a temperate pond-breeding anuran (the ... -
Historical demographic processes dominate genetic variation in ancient Atlantic cod mitogenomes
(Journal article; Peer reviewed, 2021)Ancient DNA (aDNA) approaches have been successfully used to infer the long-term impacts of climate change, domestication, and human exploitation in a range of terrestrial species. Nonetheless, studies investigating such ... -
History and evolution of the afroalpine fora: in the footsteps of Olov Hedberg
(Journal article; Peer reviewed, 2021)The monumental work of Olov Hedberg provided deep insights into the spectacular and fragmented tropical alpine flora of the African sky islands. Here we review recent molecular and niche modelling studies and re-examine ... -
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, ... -
Integrated Taxonomic Revision of Afrotropical Xyleborinus (Curculionidae: Scolytinae) Reveals High Diversity After Recent Colonization of Madagascar
(Journal article; Peer reviewed, 2021)The ambrosia beetle genus Xyleborinus Reitter, 1913 is particularly species rich in Madagascar where the genus exhibits extraordinary morphological variation not seen elsewhere. This study provides the first detailed ... -
Integrative taxonomy reveals a cryptic species of the nudibranch genus Polycera (Polyceridae) in European waters
(Journal article; Peer reviewed, 2020)This work aimed to test whether the colour variability featured by the European nudibranch Polycera quadrilineata is consistent with the concept of a single polychromatic species or may hide multiple lineages. Samples from ... -
Integrative taxonomy reveals a new species, Nephroma orvoi, in the N. parile species complex (lichenized Ascomycota)
(Journal article; Peer reviewed, 2020)Our knowledge of the diversity and distribution of many groups of lichens remains poor due to unclear species boundaries and challenging species identification. We have studied the medium sized to large foliose lichen ... -
Interrogating genomic-scale data to resolve recalcitrant nodes in the Spider Tree of Life
(Journal article; Peer reviewed, 2020)Genome-scale data sets are converging on robust, stable phylogenetic hypotheses for many lineages; however, some nodes have shown disagreement across classes of data. We use spiders (Araneae) as a system to identify the ... -
Intraspecific dental variations in the deep-sea shark Etmopterus spinax and their significance in the fossil record
(Journal article; Peer reviewed, 2020)An important character on several taxonomic levels for shark identification is the tooth morphology. Sharks show a variety of highly specialized dentitions reflecting adaptations to their feeding habits. Intraspecific ... -
