ABSTRACT 1 Stable isotope analysis (SIA) has the potential to become a widespread tool in
mammalian ecology, because of its power in resolving the ecological and behavioural …

Predation and scavenging have been classically understood as independent processes,
with predator–prey interactions and scavenger–carrion relationships occurring separately …

Although facultative scavenging is very common, little is known about the factors governing
carrion acquisition by vertebrates. We examined the influence of carcass characteristics …

While population cycles are geographically widespread, it is on arctic tundra that such
cycles appear to be most influential for the functioning of the whole ecosystem. We give an …

The high Arctic has the world's simplest terrestrial vertebrate predator–prey community, with
the collared lemming being the single main prey of four predators, the snowy owl, the Arctic …

The benefits and challenges of integrating traditional ecological knowledge and scientific
knowledge have led to extensive discussions over the past decades, but much work is still …

The onshore deposition of macroalgal and macrophyte wrack provides a potentially
significant marine subsidy to intertidal and supratidal herbivore and decomposer …

Arctic terrestrial herbivores influence tundra carbon and nutrient dynamics through their
consumption of resources, waste production, and habitat‐modifying behaviors. The strength …

Tissues of subsistence-harvested Arctic mammals were analyzed for silver (Ag), cadmium
(Cd), and total mercury (THg). Muscle (or total body homogenates of potential fish and …

Scavenging is a widespread phenomenon in vertebrate communities which has rarely been
accounted for, in spite of playing an essential role in food webs by enhancing nutrient …
