Consecutive earthquakes temporarily restructured the zooplankton community in an Alpine Lake [PDF]
, 2012 Two consecutive earthquakes temporary changed a zooplankton community in a high-mountain Lake Krn (altitude 1383 m a.s.l.). It was dominated by the eurytherm copepod, Cyclops vicious, until 1998, when the first earthquake hit the lake (EMS = 5.6).

Cryosphere changes drive an Arctic fox decline at the Arctic’s edge
, 2022 Abstract Responses of one species to changing climate may influence population dynamics of others, particularly in the Arctic where food webs are strongly linked. Specifically, changes to the cryosphere can limit prey availability for predators. We examined Arctic fox ( Vulpes lagopus

The marine side of a terrestrial carnivore: intra-population variation in use of allochthonous resources by arctic foxes. [PDF]
PLoS ONE, 2012 Inter-individual variation in diet within generalist animal populations is thought to be a widespread phenomenon but its potential causes are poorly known. Inter-individual variation can be amplified by the availability and use of allochthonous resources,
