3-D Numerical Study of a Bottom Ramp Fish Passage Using Smoothed Particle Hydrodynamics
(Peer reviewed; Journal article, 2021)Worldwide, the overwhelming number of man-made barriers in fluvial systems has been identified as one of the major causes of the reported staggering average declines of migratory fish. Fish passages have been shown to help ... -
A continent-wide search for Antarctic petrel breeding sites with satellite remote sensing
(Journal article; Peer reviewed, 2018)The Antarctic petrel (Thalassoica antarctica) has been identified as a key species for monitoring the status and health of the Southern Ocean and Antarctic ecosystems. Breeding colonies of the Antarctic petrel are often ... -
A preliminary overview of the corticioid Atractiellomycetes (Pucciniomycotina, Basidiomycetes)
(Journal article, 2018)The taxonomy of the corticioid fungi from the class Atractiellomycetes (Pucciniomycotina, Basidiomycetes) currently addressed to the genus Helicogloea, is revised based on morphological and nuclear ribosomal DNA (ITS and ... -
A review of acoustic telemetry in Europe and the need for a regional aquatic telemetry network
(Journal article; Peer reviewed, 2018)Background: Globally, there are a large and growing number of researchers using biotelemetry as a tool to study aquatic animals. In Europe, this community lacks a formal network structure. The aim of this study is to review ... -
The accuracy and precision of age determination by dental cementum annuli in four northern cervids
(Peer reviewed; Journal article, 2020)Individual age is an important element in models of population demographics, but the limitations of the methods used for age determination are not always clear. We used known-age data from moose (Alces alces), red deer ... -
Adaptive responses of animals to climate change are most likely insufficient
(Journal article; Peer reviewed, 2019)Biological responses to climate change have been widely documented across taxa and regions, but it remains unclear whether species are maintaining a good match between phenotype and environment, i.e. whether observed trait ... -
Additions to the knowledge of Encyrtidae (Hymenoptera: Chalcidoidea) from Norway, with descriptions of two new species
(Peer reviewed; Journal article, 2024)Two genera of Encyrtidae (Hymenoptera: Chalcidoidea) are for the first time recorded from Norway: Dusmetia Mercet, 1921 and Prionomastix Mayr, 1876. Six new species records for the country are presented, including two newly ... -
Advancing restoration ecology: A new approach to predict time to recovery
(Journal article; Peer reviewed, 2018)1. Species composition is a vital attribute of any ecosystem. Accordingly, ecological restoration often has the original, or “natural,” species composition as its target. However, we still lack adequate methods for predicting ... -
Agonimia globulifera new to mainland Norway
(Journal article; Peer reviewed, 2019)During an excursion to Vetvika, Bremanger municipality in Sogn og Fjordane in search of rare bryo-phytes, the first author made a collection of small black perithecia overgrowing bryophytes on shellsand. The collection was ... -
Alien plants, animals, fungi and algae in Norway: an inventory of neobiota
(Journal article; Peer reviewed, 2019)We present the results of an inventory and status assessment of alien species in Norway. The inventory covered all known multicellular neobiota, 2496 in total, 1039 of which were classified as naturalised. The latter ... -
Alien species and the Water Framework Directive: Recommendations for assessing ecological status in fresh waters in Norway
(Peer reviewed; Journal article, 2022)1. Invasive alien species are recognized as a significant anthropogenic threat to freshwater ecosystems, because they may bring about the local extinction of native species and the collapse of habitat types of special ... -
Alpine garden plants from six continents show high vulnerability to ice encasement
(Journal article; Peer reviewed, 2017)Icy surfaces impose challenges for northern societies, wildlife and agriculture. However, there have been relatively few studies of the impacts of anoxic ground ice on non-agricultural plants. During the winter of 2009–2010, ... -
Animal migration to northern latitudes: environmental changes and increasing threats
(Peer reviewed; Journal article, 2022)Every year, many wild animals undertake long-distance migration to breed in the north, taking advantage of seasonally high pulses in food supply, fewer parasites, and lower predation pressure in comparison with equatorial ... -
Anisomeridium viridescens and Arthopyrenia callunae, two pyrenolichens new to Fennoscandia
(Journal article; Peer reviewed, 2018)Lichens with perithecioid ascomata (‘pyrenolichens’), especially weakly lichenized species, are poorly known in Norway, and Fennoscandia. Several new country records for Norway have been published recently (Nordén et al. ... -
Annual adult survival drives trends in Arctic-breeding shorebirds but knowledge gaps in other vital rates remain
(Peer reviewed; Journal article, 2020)Conservation status and management priorities are often informed by population trends. Trend estimates can be derived from population surveys or models, but both methods are associated with sources of uncertainty. Many ... -
Antarctic petrels ‘on the ice rocks’: wintering strategy of an Antarctic seabird
(Peer reviewed; Journal article, 2020)There is a paucity of information on the foraging ecology, especially individual use of sea-ice features and icebergs, over the non-breeding season in many seabird species. Using geolocators and stable isotopes, we defined ... -
Anthropogenic pressure on large carnivores and their prey in the highly threatened forests of Tanintharyi, southern Myanmar
(Peer reviewed; Journal article, 2022)The Tanintharyi Region in southern Myanmar is rich in biodiversity yet is facing threats from varying degrees of anthropogenic pressure. In this research we examine how anthropogenic pressures are influencing large carnivores ... -
Anti-parasite treatment and blood biochemistry in raptor nestlings
(Journal article; Peer reviewed, 2017)We investigated the effects of parasite removal on various blood clinical–chemical variables (BCCVs). BCCVs are indicators of health, reflecting, e.g., homeostasis of liver, kidney function, and bone metabolism. The study ... -
Arctic charr (Salvelinus alpinus) re-established in a formerly acidified and highly dilute mountain lake under declining acidic deposition
(Journal article; Peer reviewed, 2018)Arctic charr in Rondvatn, a formerly highly acidified mountain lake in southern Norway, was re-established through stocking. The population became extinct during the early 1980s when the lake had an annual mean pH of ... -
An artificial intelligence approach to remotely assess pale lichen biomass
(Peer reviewed; Journal article, 2022)Although generally given little attention in vegetation studies, ground-dwelling (terricolous) lichens are major contributors to overall carbon and nitrogen cycling, albedo, biodiversity and biomass in many high-latitude ...
