Ciencias Marinas, 2019 Fine-scale site fidelity in polygynous pinnipeds influences individual interactions, social stability, and gene flow; over time, demographic processes may be altered, and local extinction of some colonies may occur.

Allee Effects May Slow the Spread of Parasites in a Coastal Marine Ecosystem [PDF]
, 2011 Allee effects are thought to mediate the dynamics of population colonization, particularly for invasive species. However, Allee effects acting on parasites have rarely been considered in the analogous process of infectious disease establishment and ...

Unsustainable anthropogenic mortality disrupts natal dispersal and promotes inbreeding in leopards
Ecology and Evolution, 2020 Anthropogenic mortality of wildlife is typically inferred from measures of the absolute decline in population numbers. However, increasing evidence suggests that indirect demographic effects including changes to the age, sex, and social structure of ...

Rivista Italiana di Ornitologia - Research in Ornithology, 2021 Insistent nesting attempts by a group of European Beeeaters in a new site, a pebbly bank of the middle course of Trebbia River, northern Italy, mostly failed because of the unmovable pebbles encountered during tunnel excavation. The birds later nested in

Social bonds and genetic ties: Kinship association and affiliation in a community of bonobos (Pan paniscus) [PDF]
, 1999 Studies of captive populations of bonobos suggest that females are more gregarious than males. This seems to contradict assumed sex-differences in kinship deriving from a speciestypical dispersal pattern of female exogamy and male philopatry.

Gene diversity and female philopatry. [PDF]
Genetics, 1991 Abstract The effect of female philopatry on the apportionment of gene diversity within a population is evaluated. Even with random mate selection, the apportionment of gene diversity within and among social lineages (groups of related females) is inherently different than in classically defined demic groups.

Wildlife Biology, EarlyView.Seasonal variation in photoperiods, energetic demands, and reproductive constraints are expected to strongly influence bat activity at high latitudes, yet empirical evidence from boreal systems is limited. We used passive acoustic monitoring to examine spatial, temporal, and feeding activity patterns of bats along a boreal river basin in Sweden (64°N ...
