Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

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

open access: yesIbis, 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

Konsep restorasi dibangun guna mengembalikan sungai seperti sediakala. Secara kasat mata, sungai-sungai penuh sampah, limbah, terutama di pemukiman dan perkotaan. Kalaupun sungai dikelola, tidak memperhatikan ekosistem. Masyarakat tidak lagi memperhatikan sungai, padahal sungai alam sangat berguna bagi manusia.

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

open access: yesIbis, 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

Wintering Barnacle Geese Exhibit an Increased Behavioural Drive for Sleep After Sleep Deprivation Without a Clear EEG‐Based Sleep Rebound

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep is essential for normal physiological functioning, and sleep deprivation is typically compensated by increasing subsequent sleep duration and/or intensity. However, a recent study showed that barnacle geese (Branta leucopsis) exhibit seasonal variation in sleep homeostasis, with full recovery of sleep after sleep deprivation in summer ...
