Occurrence of the European eel in lakes in the northern part of its distribution area is limited to low-altitude coastal areas, likely due to topographical conditions
(Peer reviewed; Journal article, 2019)With the decline of the European eel, protection measures in all parts of the eel’s distribution area may be increasingly important. Norway has a vast coastline (58°–71°N), but the distribution of eel has been largely ... -
Ocean climate and egg investment in the black-legged kittiwake Rissa tridactyla
(Journal article; Peer reviewed, 2017)Birds allocate substantial resources to their eggs during the laying period, resources also needed for other concurrent costly processes such as mate acquisition, nest building and site defence. Egg and clutch sizes may ... -
Ocean currents as a potential dispersal pathway for Antarctica’s most persistent non-native terrestrial insect
(Peer reviewed; Journal article, 2021)The non-native midge Eretmoptera murphyi is Antarctica’s most persistent non-native insect and is known to impact the terrestrial ecosystems. It inhabits by considerably increasing litter turnover and availability of soil ... -
Ocean predation and mortality of adult Atlantic salmon
(Peer reviewed; Journal article, 2019) -
Ocean-wide drivers of migration strategies and their influence on population breeding performance in a declining seabird
(Journal article; Peer reviewed, 2017)Which factors shape animals’ migration movements across large geographical scales, how different migratory strategies emerge between populations, and how these may affect population dynamics are central questions in ... -
Off the conservation radar: the hidden story of Europe’s tiny pea clams (Bivalvia: Sphaeriidae)
(Peer reviewed; Journal article, 2024)This study highlights the conservation problems faced by the tiny freshwater bivalves of the family Sphaeriidae, also known as pea, pill, or fingernail clams (or mussels) in Europe. Despite their global distribution, assumed ... -
Offshore oil rigs – a breeding refuge for Norwegian Black-legged Kittiwakes Rissa tridactyla?
(Peer reviewed; Journal article, 2020)In recent decades, the population of Black-legged Kittiwake Rissa tridactyla has declined substantially in most parts of the North Atlantic. Concurrently, there has been an increased urbanisation of the species, with ... -
Omfattende spredning og bekjempelse av gjedde i Trøndelag
(Journal article, 2020)I Trøndelag er gjedda naturlig utbredt bare i Murusjøen i Muruelvvassdraget i nordøst og i noen lokaliteter i Trysilelvvassdraget i sør. Helt siden middelalderen har mennesker spredt gjedde i fylket, men spesielt i løpet ... -
On fitness and partial migration in a large herbivore – migratory moose have higher reproductive performance than residents
(Journal article; Peer reviewed, 2016)Partially migratory populations comprise both resident and migratory individuals. Th ese tactics may coexist if their demographic contribution to future generations (i.e. fitness) are equal or vary temporally with environmental ... -
On some Entoloma species (Tricholomatinae, Basidiomycota) little known or new to Norway
(Journal article, 2020)This is the second paper reporting major results from the Norwegian Entoloma project 2015- 2017. Here we present species that are new to Norway or little known, from the following smaller clades: Caeruleopolitum, Claudopus, ... -
On the relevance of animal behavior to the management and conservation of fishes and fisheries
(Peer reviewed; Journal article, 2022)There are many syntheses on the role of animal behavior in understanding and mitigating conservation threats for wildlife. That body of work has inspired the development of a new discipline called conservation behavior. ... -
One Hundred Pressing Questions on the Future of Global Fish Migration Science, Conservation, and Policy
(Journal article; Peer reviewed, 2019)Migration is a widespread but highly diverse component of many animal life histories. Fish migrate throughout the world’s oceans, within lakes and rivers, and between the two realms, transporting matter, energy, and other ... -
One-quarter of freshwater fauna threatened with extinction
(Peer reviewed; Journal article, 2025)Freshwater ecosystems are highly biodiverse1 and important for livelihoods and economic development2, but are under substantial stress3. To date, comprehensive global assessments of extinction risk have not included any ... -
Ongoing niche differentiation under high gene flow in a polymorphic brackish water threespine stickleback (Gasterosteus aculeatus) population
(Journal article; Peer reviewed, 2018)Background: Marine threespine sticklebacks colonized and adapted to brackish and freshwater environments since the last Pleistocene glacial. Throughout the Holarctic, three lateral plate morphs are observed; the low, partial ... -
Ontogenetic variation in the marine foraging of Atlantic salmon functionally links genomic diversity with a major life history polymorphism
(Peer reviewed; Journal article, 2024)The ecological role of heritable phenotypic variation in free-living populations remains largely unknown. Knowledge of the genetic basis of functional ecological processes can link genomic and phenotypic diversity, providing ... -
Ontogeny shapes individual dietary specialization in female European brown bears (Ursus arctos)
(Peer reviewed; Journal article, 2024)Individual dietary specialization, where individuals occupy a subset of a population’s wider dietary niche, is a key factor determining a species resilience against environmental change. However, the ontogeny of individual ... -
Open Access Sympatric Atlantic puffins and razorbills show contrasting responses to adverse marine conditions during winter foraging within the North Sea
(Movement Ecology;, Peer reviewed; Journal article, 2019)Background: Natural environments are dynamic systems with conditions varying across years. Higher trophic Level consumers may respond to changes in the distribution and quality of available prey by moving to locate New ... -
OpenStreetMap history for intrinsic quality assessment: Is OSM up-to-date?
(Peer reviewed; Journal article, 2019)OpenStreetMap (OSM) is a well-known crowdsourcing project which aims to create a geospatial database of the whole world. Intrinsic approaches based on the analysis of the history of data, i.e. its evolution over time, have ... -
Operationalising ecosystem service assessment in Bayesian Belief Networks: experiences within the OpenNESS project
(Journal article; Peer reviewed, 2017)Nine Bayesian Belief Networks (BBNs) were developed within the OpenNESS project specifically for modelling ecosystem services for case study applications. The novelty of the method, its ability to explore problems, to ... -
Optimal approach for upstream fish passage design: One-size-fits-all or made-to-order?
(Peer reviewed; Journal article, 2023)Nearly 60,000 large dams (higher than 15 m) occur worldwide in addition to an estimated16 million smaller impoundments with individual surface areas larger than 100 m2.Theresulting habitat fragmentation threatens global ...
