Water chemistry, zooplankton and benthos in small lakes within the distribution area of the rare European pool frog Pelophylax lessonae (Camerano) in Norway
(Journal article; Peer reviewed, 2020)In June 2018, water chemistry, benthos and zooplankton were investigated in 7 small lakes/ ponds within the key area of the European pool frog Pelophylax lessonae (Camerano) in Norway. The geographic distribution of the ... -
What are the effects of herbivore diversity on tundra ecosystems? A systematic review protocol
(Peer reviewed; Journal article, 2022)Background Changes in the diversity of herbivore communities can strongly influence the functioning of northern ecosystems. Different herbivores have different impacts on ecosystems because of differences in their diets, ... -
What are the impacts of reindeer/caribou (Rangifer tarandus L.) on arctic and alpine vegetation? A systematic review
(Peer reviewed; Journal article, 2015)Background:The reindeer (or caribou,Rangifer tarandusL.) has a natural range extending over much of Eurasia’s and North America’s arctic, alpine and boreal zones, yet its impact on vegetation is still unclear. This lack ... -
What evidence exists for temporal variability in Arctic terrestrial and freshwater biodiversity throughout the Holocene? A systematic map protocol
(Peer reviewed; Journal article, 2022)Background The Arctic tundra is subject to the greatest climate change-induced temperature rises of any biome. Both terrestrial and freshwater biota are responding to recent climate warming through variability in their ... -
What is the influence of a reduction of planktivorous and benthivorous fish on water quality in temperate eutrophic lakes? A systematic review
(Peer reviewed; Journal article, 2015)Background:In recent decades, many attempts have been made to restore eutrophic lakes through biomanipulation.Reducing the populations of planktivorous and benthivorous fish (either directly or through stocking of piscivorous ... -
When DNA barcoding and morphology mesh: Ceratopogonidae diversity in Finnmark, Norway
(Journal article; Peer reviewed, 2014)DNA barcoding in Ceratopogonidae has been restricted to interpreting the medically and veterinary important members of Culicoides Latreille. Here the technique is utilised, together with morphological study, to interpret ... -
When soft waters becomes softer; drivers of critically low levels of Ca in Norwegian lakes
(Journal article; Peer reviewed, 2017)In this study, we analyzed long-term trends in calcium (Ca) concentrations for 70 Norwegian lakes spanning a broad geographical range and for a wide range of ambient drivers. A striking decline in Ca concentrations was ... -
When standard DNA barcodes do not work for species identifcation: intermixed mitochondrial haplotypes in the Jaera albifrons complex(Crustacea: Isopoda)
(Journal article; Peer reviewed, 2024)Here, we characterise the standard “Folmer region” of the mitochondrial cytochrome c oxidase subunit 1 (CO1) marker and a fragment of nuclear 28S marker in four species of the Jaera albifrons complex. Jaera albifrons (Leach, ... -
Whole-genome sequencing of African dogs provides insights into adaptations against tropical parasites
(Journal article; Peer reviewed, 2017)Natural selection in domestic dogs is of great interest in evolutionary biology since dogs have migrated to every inhabited continent of the world alongside humans, and adapted to diverse environments. Here, we explored ... -
Why do we find dead bumblebees under linden trees?
(Peer reviewed; Journal article, 2022)1. Linden trees (Tilia spp.) have for a long time been associated with bumblebee (Bombus spp.) mortality in Europe and North America. Several explanations have been suggested for this phenomenon. This study aimed to explore ... -
Why don't all species overexploit?
(Peer reviewed; Journal article, 2021)Overexploitation of natural resources is often viewed as a problem characteristic of only the human species. However, any species could evolve a capacity to overexploit its essential resources through natural selection and ... -
Wild salmonids are running the gauntlet of pathogens and climate as fish farms expand northwards
(Peer reviewed; Journal article, 2020)Salmon farming has multiplied from a side business of coastal farmers to one of the world's major aquaculture species. This has dramatically altered the disease dynamics between farmed and wild salmonids. As salmon fish ... -
Will borealization of Arctic tundra herbivore communities be driven by climate warming or vegetation change?
(Peer reviewed; Journal article, 2021)Poleward shifts in species distributions are expected and frequently observed with a warming climate. In Arctic ecosystems, the strong warming trends are associated with increasing greenness and shrubification. Vertebrate ... -
Xylopsora canopeorum (Umbilicariaceae), a new lichen species from the canopy of Sequoia sempervirens
(Journal article; Peer reviewed, 2018)Xylopsora canopeorum Timdal, Reese Næsborg & Bendiksby is described as a new species occupying the crowns of large Sequoia sempervirens trees in California, USA. The new species is supported by morphology, anatomy, secondary ... -
