Improvement in survivorship: The key for population recovery? [PDF]
, 2016 In northern Patagonia, commercial harvesting of South American sea lions, Otaria flavescens, from 1920 to 1960, decimated its population abundance. Population recovery was not immediate after hunting ceased in 1962.

Polar Research, 2021 Philopatry influences animal distribution and can lead to a kinship-based spatial structure, where proximity and relatedness are tightly linked. In the Barents Sea region, polar bears (Ursus maritimus) of the coastal ecotype remain year-round within the ...

Delayed dispersal and the cost and benefits of different routes to independent breeding in a cooperative breeding bird [PDF]
, 2016 Why sexually mature individuals stay in groups as non-reproductive subordinates is central to the evolution of sociality and cooperative breeding. To understand such delayed dispersal, its costs and benefits need to be compared with those of permanently ...

Diverse demographic factors influence apparent juvenile survival in a migratory songbird
Ecosphere, 2021 To better understand the dynamics of avian populations and their role in population trends, we require an in‐depth understanding of the factors influencing the survival of adults and juveniles.

Ecology and Evolution, 2021 Seabirds, particularly Procellariiformes, are highly mobile organisms with a great capacity for long dispersal, though simultaneously showing high philopatry, two conflicting life‐history traits that may lead to contrasted patterns of genetic population ...

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.

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 ...
