Contemporary ocean warming and freshwater conditions are related to later sea age at maturity in Atlantic salmon spawning in Norwegian rivers
(Journal article; Peer reviewed, 2012)Atlantic salmon populations are reported to be declining throughout its range, raising major management concerns. Variation in adult fish abundance may be due to variation in survival, growth, and timing of life history ... -
Deep sympatric mitochondrial divergence without reproductive isolation in the common redstart Phoenicurus phoenicurus
(Journal article; Peer reviewed, 2012)Mitochondrial DNA usually shows low sequence variation within and high sequence divergence among species, which makes it a useful marker for phylogenetic inference and DNA barcoding. A previous study on the common redstart ... -
Evaluating citizen science data for forecasting species responses to national forest management
(Journal article; Peer reviewed, 2016)The extensive spatial and temporal coverage of many citizen science datasets (CSD) makes them appealing for use in species distribution modeling and forecasting. However, a frequent limitation is the inability to validate ... -
Evolutionary responses to a changing climate: Implications for reindeer population viability
(Journal article; Peer reviewed, 2017)If we want to understand how climate change affects long-lived organisms, we must know how individuals allocate resources between current reproduction and survival. This trade-off is affected by expected environmental ... -
Framing pictures: A conceptual framework to identify and correct for biases in detection probability of camera traps enabling multi‐species comparison
(Journal article; Peer reviewed, 2019)Obtaining reliable species observations is of great importance in animal ecology and wildlife conservation. An increasing number of studies use camera traps (CTs) to study wildlife communities, and an increasing effort is ... -
Good-bye to tropical alpine plant giants under warmer climates? Loss of range and genetic diversity in Lobelia rhynchopetalum
(Journal article; Peer reviewed, 2016)The main aim of this paper is to address consequences of climate warming on loss of habitat and genetic diversity in the enigmatic tropical alpine giant rosette plants using the Ethiopian endemic Lobelia rhynchopetalum as ... -
How to induce defense responses in wild plant populations? Using bilberry (Vaccinium myrtillus) as example
(Journal article; Peer reviewed, 2017)Inducible plant defense is a beneficial strategy for plants, which imply that plants should allocate resources from growth and reproduction to defense when herbivores attack. Plant ecologist has often studied defense ... -
Intensity of space use reveals conditional sex-specific effects of prey and conspecific density on home range size
(Journal article; Peer reviewed, 2016) -
Long-lasting effects of logging on beetles in hollow oaks
(Journal article; Peer reviewed, 2018)There is growing evidence that biodiversity is important for ecosystem functions. Thus, identification of habitat requirements essential for current species richness and abundance to persist is crucial. Hollow oaks (Quercus ... -
Mismatch between fishway operation and timing of fish movements: a risk for cascading effects in partial migration systems
(Peer reviewed, 2016)Habitat fragmentation is a growing problem worldwide. Particularly in river systems, numerous dams and weirs hamper the movement of a wide variety of species. With the aim to preserve connectivity for fish, many barriers ... -
Multiannual effects of induced plant defenses: Are defended plants good or bad neighbors?
(Journal article; Peer reviewed, 2018)Defenses induced by herbivore feeding or phytohormones such as methyl jasmonate (MeJA) can affect growth, reproduction, and herbivory, not only on the affected individual but also in its neighboring plants. Here, we report ... -
Prediction of biodiversity hotspots in the Anthropocene: The case of veteran oaks
(Journal article; Peer reviewed, 2017)Over the past centuries, humans have transformed large parts of the biosphere, and there is a growing need to understand and predict the distribution of biodiversity hotspots influenced by the presence of humans. Our basic ... -
Taking a trip to the shelf: Behavioral decisions are mediated by the proximity to foraging habitats in the black-legged kittiwake
(Journal article; Peer reviewed, 2017)For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availability. Worldwide, these marine habitats are being altered by changes in climate and ... -
Temporal variation in trophic relationships among three congeneric penguin species breeding in sympatry
(Journal article; Peer reviewed, 2018)Penguins are a monophyletic group in which many species are found breeding sympatrically, raising questions regarding how these species coexist successfully. Here, the isotopic niche of three sympatric pygoscelid penguin ... -
The potential influence of Atlantic salmon Salmo salar and brown trout Salmo trutta on density and breeding of the white-throated dipper Cinclus cinclus
(Journal article; Peer reviewed, 2018)Interactions between birds and fish are often overlooked in aquatic ecosystems. We studied the influence of Atlantic salmon and brown trout on the breeding population size and reproductive output of the white-throated ... -
Timing and pattern of annual silver eel migration in two European watersheds are determined by similar cues
(Journal article; Peer reviewed, 2017)Many animals perform long-distance migrations in order to maximize lifetime reproductive success. The European eel migrates several thousand kilometers between their feeding habitats in continental waters (fresh-,brackish, ... -
Where do the treeless tundra areas of northern highlands fit in the global biome system: toward an ecologically natural subdivision of the tundra biome
(Peer reviewed, 2015)According to some treatises, arctic and alpine sub-biomes are ecologically similar, whereas others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands fall outside of the two recent ...
