Does Survey Angling CPUE Reflect Population Density of Northern Pike (Esox lucius) in Small Boreal Lakes?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Knowing the relationship between catch per unit effort (CPUE) and population density is crucial for the management of recreational fisheries. We conducted standardized angling for pike in 16 lakes (3.4–22.1 ha) to test whether lure type, color, and pike density affect CPUE and the size of captured fish.

Biophysical Factors Controlling Spatiotemporal Variability in Fishes' Early Life History Distribution in the Kattegat Ecosystem

Fisheries Oceanography, EarlyView.
ABSTRACT The Kattegat Sea acts as a nursery area for several fishes, exhibiting complex ichthyoplankton dynamics influenced by environmental factors and species‐specific traits. We investigated factors influencing spatiotemporal variability in yolk‐sac larvae presence and areal density for three economically and ecologically important fishes: sandeel ...

Baltic-nordic relations: implications for baltic security

, 1995
Seit dem Ende des Ost-West-Konflikts stehen die baltischen Staaten vor einem Sicherheitsdilemma. Seit der Erlangung ihrer Unabhängigkeit 1991 versuchen sie sich von Osteuropa zu lösen und enger mit dem Westen zusammenzuarbeiten. Dem stehen die Interessen Rußlands und die auf Rußland konzentrierten Interessen des Westens entgegen.

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

Ibis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Connectivity between breeding sites, wintering areas, and migration routes in Common Terns (Sterna hirundo) breeding in the Western Palaearctic

Ibis, EarlyView.
Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...

Low breeding propensity in a declining Arctic‐breeding swan revealed by telemetry data

Ibis, EarlyView.
Many migratory bird populations are declining in the face of habitat degradation and climate change, making it important to identify which stages of their annual cycle are most affected in order to guide conservation measures. The Bewick's Swan Cygnus columbianus bewickii, an Arctic‐breeding waterfowl species, has suffered a dramatic population decline

Time‐stressed Bar‐tailed Godwits exploit novel prey during migratory fuelling

Ibis, EarlyView.
Long‐distance migratory birds breeding in the Arctic face challenges as earlier snowmelt shifts the timing of vital resources. To keep up with these advancements, birds will need to modify their migration. Higher fuelling rates during stopover have been identified as a critical mechanism for accelerating migration, but this requires adequate food ...
