Mitigation measures for downstream-migrating Atlantic salmon smolts (Salmo salar L.) are commonly insufficiently attractive to enable safe entrance and passage with no delay. Combining 2D telemetry with hydrodynamic modelling ...

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 ...

Wind power has become an increasingly important source of renewable energy in Norway. Current demand and production capacity have exceeded expectations stipulated in energy policies a few years back. Wind power affects ...

Farmed salmon escape and interbreed with wild Atlantic salmon on a large scale. We studied introgression of mitochondrial haplotypes from farmed Atlantic salmon originating from the Eastern Atlantic phylogenetic group to ...

Novel methods for sampling and characterizing biodiversity hold great promise for re-evaluating patterns of life across the planet. The sampling of airborne spores with a cyclone sampler, and the sequencing of their DNA, ...

Scheduling between mates in species with long-term pair bonds can be essential for positive fitness. The annual cycle in photoperiod is the primary environmental cue used by many animals to synchronize behavior and physiology ...

Global climate change has altered the timing of seasonal events (i.e., phenology) for a diverse range of biota. Within and among species, however, the degree to which alterations in phenology match climate variability ...

Mysis segerstralei is distributed over a wide geographic area and in habitats with a variety of salinity conditions, including marine and brackish waters around Svalbard. The species has seldom been found in freshwater ...

As demand for renewable energy is rising, wind power development is rapidly growing worldwide. In its wake, conficts arise over land use changes converting pristine nature into industrial power plants and its associated ...

Measurements of individual body length at different life stages are critical in understanding fish ecology and evolution. Such data can be obtained via back-calculation from measurements of fish scales or by using the size ...
