Species can either maintain a certain social organization in different habitats or show different social organizations in similar habitats. The reasons underlying this variability are not always clear but might have consequences for population dynamics, especially under changing environmental conditions. Among mammals, the primate genus Microcebus lives in small groups of closely related females, derived from female philopatry...

The Arctic is getting warmer and wetter. Here, we document two independent examples of how associated extreme precipitation patterns have severe implications for high Arctic ecosystems. The events stand out in a 23-year record of continuous observations of a wide range of ecosystem parameters and act as an early indication of conditions projected to increase in the future. In NE Greenland, August 2015, one-quarter of the avera...

Two groups of subspecies of the door snail Charpentieria itala are distributed in a mosaic pattern in the Southern Alps. Some subspecies that morphologically resemble Charpentieria stenzii occur at exposed rocks at higher altitudes, whereas other subspecies live on more humid rocks at lower altitudes. This pattern can be explained by two alternative hypotheses. Either the stenzii ‐like or ‘stenzioid’ subspecies have a common o...

Our collaborative work focused on understanding the system of mechanisms influencing the mortality of juvenile pink salmon ( Oncorhynchus gorbuscha ) in Prince William Sound, Alaska. Coordinated field studies, data analysis and numerical modelling projects were used to identify and explain the mechanisms and their roles in juvenile mortality. In particular, project studies addressed the identification of major fish and bird pr...

Five years of field, laboratory, and numerical modelling studies demonstrated ecosystem‐level mechanisms influencing the mortality of juvenile pink salmon and Pacific herring. Both species are prey for other fishes, seabirds, and marine mammals in Prince William Sound. We identified critical time‐space linkages between the juvenile stages of pink salmon and herring rearing in shallow‐water nursery areas and seasonally varying...
