Climate change and phenological responses of two seabird species breeding in the high-Arctic
The timing of breeding is a life-history trait that can greatly affect fitness, because suc- cessful reproduction depends on the match between the food requirements for raising young and the seasonalExpand

Diversification of Nitrogen Sources in Various Tundra Vegetation Types in the High Arctic
Low nitrogen availability in the high Arctic represents a major constraint for plant growth, which limits the tundra capacity for carbon retention and determines tundra vegetation types. The limitedExpand

The influence of a seabird colony on abundance and species composition of water bears (Tardigrada) in Hornsund (Spitsbergen, Arctic)
Abstract Seabirds in the Arctic are known to link marine and terrestrial ecosystems. They feed in the sea and breed on land, where they deposit enormous amounts of guano. Soil in the vicinity ofExpand

The impact of different hydrographic conditions and zooplankton communities on provisioning Little Auks along the West coast of Spitsbergen
Abstract Composition and abundance of zooplankton were studied simultaneously with feeding ecology of planktivorous Little Auks (Alle alle) in two different sea shelf areas of West Spitsbergen,Expand

Potentially pathogenic yeast isolated from the throat and cloaca of an Arctic colonial seabird: the little auk (Alle alle)
Yeasts are a distinctive group of microfungi, but compared to other microorganisms, their ecological function and biodiversity are poorly known. This is especially so where polar ecosystems areExpand

Foraging by little auks in the distant marginal sea ice zone during the chick-rearing period
During the chick-rearing period, little auks Alle alle adopt a bimodal foraging strategy, alternating long trips with several short ones. It has been postulated that they reach more remote areasExpand

Foraging closer to the colony leads to faster growth in little auks
2 Institute of Oceanology, Polish Academy of Sciences, ul. Powstancow Warszawy 55, 81-712 Sopot, Poland ABSTRACT: Knowledge of foraging behaviour is essential to understand both the ecological rolesExpand

Response of Dovekie to Changes in Food Availability
Abstract Dovekie (Alle alle) parents feed their chicks almost exclusively with high energy Arctic zooplankton associated with cold polar waters. In years with a stronger influx of warm AtlanticExpand

Parental efforts of an Arctic seabird, the little auk Alle alle, under variable foraging conditions
Abstract Observed large-scale changes in climate and oceanography, which are especially pronounced in the Arctic, represent profound challenges for upper trophic predators. Knowledge about the extentExpand
