Predicting the impact of global climate change on the biosphere has become one of the most important efforts in ecology. Ecosystems worldwide are changing rapidly as a consequence of global warming, yet our understanding of the consequences of these changes on populations is limited. The North Atlantic Oscillation (NAO) has been used as a proxy for “climate” in several ecological studies, but this ...

Reindeer herding in Finnmark has been widely perceived during the last few decades as a perfect example of the tragedy of the commons. The present article claims that this discourse relies on flawed assumption regarding land tenure. Our historical analysis of the term ‘common’ in relation to resources in Finnmark shows the term to reflect a misunderstanding of local categories, practices, and concerns ...

Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic founder effect on five islands is associated with dispersal distance, island size and species traits. Most species colonized postglacially via multiple dispersal events from several ...

In many seabird studies, single annual proxies of prey abundance have been used to explain variability in breeding performance, but much more important is probably the timing of prey availability relative to the breeding season when energy demand is at a maximum. Until now, intraseasonal variation in prey availability has been difficult to quantify in seabirds. Using a state-of-the-art ocean ...

Som oppfølging av St. meld. 21 Norsk klimapolitikk (2011-2012) vurderer regjeringen ulike tiltak for å nå målet om et nettoutslipp av klimagasser innen 2030. I denne sammenheng skal Klima og forurensingsdepartementet (Klif), Direktoratet for naturforvaltning (DN), Statens landbruksforvaltning (SLF) og Norsk institutt for skog og landskap (Skog og Landskap) utvikle miljøkriterier for planting av ...
