Linking climate change to lemming cycles
TLDR
It is shown that winter weather and snow conditions, together with density dependence in the net population growth rate, account for the observed population dynamics of the rodent community dominated by lemmings in an alpine Norwegian core habitat between 1970 and 1997, and predict the observed absence of rodent peak years after 1994.
ON THE COST OF REPRODUCTION IN LONG-LIVED BIRDS: THE INFLUENCE OF ENVIRONMENTAL VARIABILITY
TLDR
A model of the optimal balance between reproductive effort and adult survival for long-lived birds breeding in a stochastic environment is presented and increasing clutch size in the model is examined to examine the optimal response of the two genotypes to an experimental brood size manipulation.
Multicolony tracking reveals the winter distribution of a pelagic seabird on an ocean basin scale
Aim  An understanding of the non‐breeding distribution and ecology of migratory species is necessary for successful conservation. Many seabirds spend the non‐breeding season far from land, and
Leads in Arctic pack ice enable early phytoplankton blooms below snow-covered sea ice
TLDR
Phytoplankton blooms beneath snow-covered ice might become more common and widespread in the future Arctic Ocean with frequent lead formation due to thinner and more dynamic sea ice despite projected increases in high-Arctic snowfall.
Small rodent winter survival: snow conditions limit access to food resources.
TLDR
The results suggest that the snow cover reduces survival in winter by physically enclosing the vegetation in ice and thus reducing access to otherwise available food resources and suggest incorporating climate variables in future small rodent models.
Climate fluctuation effects on breeding of blue penguins (Eudyptula minor)
TLDR
The probability of a newly hatched chick surviving to fledging was dependent on whether large‐scale climatic conditions prevailed, whereas hatching success and overall breeding success showed no correlation with climate perturbations.
Sheep grazing and rodent populations: evidence of negative interactions from a landscape scale experiment
TLDR
It is shown that negative interactions between large ungulates and small rodents may be species-specific and negative population consequences for the rodent population appear above threshold ungulate densities.
Flexibility in the bimodal foraging strategy of a high Arctic alcid, the little auk Alle alle
TLDR
It is found that the foraging pattern of the little auk was flexible and could be adjusted at three levels: the length of long-trips, the frequency of short-Trips, and the total time spent foraging, which resulted in reduced provisioning rates of chicks despite the fact that birds also increased the time allocated to foraging.
