Population change in breeding boreal waterbirds in a 25-year perspective : What characterises winners and losers?

Understanding drivers of variation and trends in biodiversity change is a general scientific challenge, but also crucial for conservation and management. Previous research shows that patterns of increase and decrease are not always consistent at diff

Global measures of biodiversity indicate consistent decline, but trends reported for local communities are more varied. Therefore, we need better understanding of mechanisms that drive changes in diversity of local communities and of differences in t

Eurasian migratory duck species represent a natural resource shared between European countries. As is evident throughout human harvest history, lack of coordinated management and monitoring at appropriate levels often leads to 'the tragedy of the com

Nesting mallards (Anas platyrhynchos) forecast brood-stage food limitation when selecting habitat: experimental evidence

Autor: Petri Nummi, Johan Elmberg, Hannu Pöysä, Kjell Sjöberg

Publikováno v: Oecologia. 122(4)

By combining and reanalysing data from two independent field experiments we explore whether food limitation at the brood stage affects habitat selection in nesting mallards (Anas platyrhynchos). In an introduction experiment we found that, independen

Survival of female capercaillie Tetrao urogallus in northern Sweden

Autor: Per-Arne Åhlen, Kjell Sjöberg, Maria Hörnell-Willebrand, Tomas Willebrand

Publikováno v: Wildlife Biology

We studied survival and cause-specific mortality of radio-marked capercaillie Tetrao urogallus females relative to habitat type in northern Sweden during 2000-2004. Our high-mountain area (1,600 km2) consisted of the alpine transition zone from Norwa
