Migratory bird distributions are inherently dynamic and vary with seasons, but are also increasingly influenced by climate and land-use changes. Understanding these shifts is crucial for interpreting ecosystem dynamics and guiding future conservation efforts. In this study, we analysed 187,779 resightings (1985–2021) of 5,120 colour-banded Common Cranes ( Grus grus ), originating from 8 northern European countries, to examine...

Saithe ( Pollachius virens ) is a semipelagic North Atlantic species supporting an important fishery. In the North Sea, saithe spawn east of the Shetland Islands, with larvae recruiting to coastal areas. Understanding the interaction between abiotic and biotic factors influencing larval dispersal is crucial for assessing their population structure. However, the swimming and orientation behaviors of saithe larvae, and their eff...

The European eel hatches in the Sargasso Sea and migrates across the Atlantic Ocean toward Europe. At the continental shelf, larvae metamorphose into glass eels and then recruit to coastal habitats and estuaries. Among other cues, glass eels orient in situ using lunar cues, but what role this lunar compass plays in their recruitment to the coast is unknown. To assess this, we incorporated empirical in situ observations of glas...

Norway has complicated dynamics in the coastal ocean and in the fjords. In this area is also the largest salmon aquaculture industry in the world. The salmon industry is valuable for Norwegian economy worth more than 60 billion NOK. Thus, it is important to know the physical oceanography along the coast, even variability on short temporal and spatial scales (h/km), to be able to quantify environmental effects of the aquacultur...

Aim Previous research on how climatic niches vary across species ranges has focused on a limited number of species, mostly invasive, and has not, to date, been very conclusive. Here we assess the degree of niche conservatism between distant populations of native alpine plant species that have been separated for thousands of years. Location European A lps and F ennoscandia. Methods Of the studied pool of 888 terrestrial vascula...

The large‐scale population genetic structure of northern shrimp, Pandalus borealis , was investigated over the species’ range in the North Atlantic, identifying multiple genetically distinct groups. Genetic divergence among sample localities varied among 10 microsatellite loci (range: F ST = −0.0002 to 0.0475) with a highly significant average ( F ST = 0.0149; P F ST = 0.0004; P = 0.33). Spatial genetic patterns were compared...

Recent studies from mountainous areas of small spatial extent ( 2 ) suggest that fine‐grained thermal variability over tens or hundreds of metres exceeds much of the climate warming expected for the coming decades. Such variability in temperature provides buffering to mitigate climate‐change impacts. Is this local spatial buffering restricted to topographically complex terrains? To answer this, we here study fine‐grained therm...

Whether climate change will turn cold biomes from large long‐term carbon sinks into sources is hotly debated because of the great potential for ecosystem‐mediated feedbacks to global climate. Critical are the direction, magnitude and generality of climate responses of plant litter decomposition. Here, we present the first quantitative analysis of the major climate‐change‐related drivers of litter decomposition rates in cold no...
