Social and individual features affecting natal dispersal in the colonial Lesser Kestrel [PDF]
, 2012 Causes of natal dispersal were studied in an isolated population of the migratory, facultatively colonial Lesser Kestrel (Falco naumanni) in northeastern Spain.

Frontiers in Marine Science, 2017 A thorough understanding of movement patterns of a species is critical for designing effective conservation and management initiatives. However, generating such information for large marine vertebrates is challenging, as they typically move over long ...

A REEXAMINATION OF FACTORS INFLUENCING PHILOPATRY IN RODENTS [PDF]
Journal of Mammalogy, 2003 The costs and benefits of philopatry (remaining at the natal nest) have been discussed in numerous papers. Nevertheless, there is still debate about the relative importance of factors that favor philopatry, which can result in the formation of social groups.

Breeding Dispersal and Philopatry in the Tree Swallow [PDF]
The Condor, 2004 AbstractTo study the patterns and determinants of philopatry and breeding dispersal in the Tree Swallow (Tachycineta bicolor) we analyzed the records of 356 males and 1459 females captured in more than one breeding year around Ithaca, New York. Of these captures, only 4% of male and 14% of female breeders dispersed to a new site for breeding.

Ibis, EarlyView.Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

Ibis, EarlyView.Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Frontiers of Biogeography, 2012 The evolutionary processes driving patterns of genetic diversity and differentiation, and ultimately leading to speciation, are poorly understood. The aim of this thesis was to investigate the effects of environmental and biological mechanisms on gene ...

Zoologia (Curitiba), 2018 Neotropical bats are recognized as effective seed dispersers, especially of small-seeded pioneer plants during early stages of forest regeneration. There had been few reports on the ecology of the bat Pygoderma bilabiatum (Wagner, 1843), which appears to

Stable isotope signature of philopatry and dispersal in a migratory songbird [PDF]
Proceedings of the National Academy of Sciences, 2002 Stable isotope analysis is widely promoted as a practical method for tracing the geographic origins of migratory birds. However, the extent to which geospatial patterns of isotope ratios in avian tissues are influenced by age-specific, altitudinal, and temporal factors remains largely unexplored. We measured carbon ( 13
