Winter browsing by moose (Alces alces) in a forested mountainous landscape of west–central Sweden

open access: yesWildlife Biology, EarlyView.
Browsing ecology involving ungulates and their food resource is complex as consumption may reflect responses to various factors, such as quantity and quality of browse species. This study investigated winter browsing by moose Alces alces in a mountainous landscape of west–central Sweden, characterized by Norway spruce Picea abies production forests ...

Noise pollution as a major disturbance of avian predation in Amsterdam

open access: yesWildlife Biology, EarlyView.
Trophic interactions play a key role in maintaining ecological balance. In urban environments, avian predation has been demonstrated to be particularly important due to its effects on community structure, pest control, and nutrient cycling. As humanity relies upon ecosystem services for sustenance, and with 70% of the global population projected to ...

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this
