Female philopatry and spatial organization in the raccoon (Procyon lotor) [PDF]
, 1997 Among mammals, some of the most common types of cohesive social groupings originate form natal philopatry through the extended mother family. The recognition that females among some solitary mammals demonstrate natal philopatry suggests that an important

First breeding colony of Audouin's Gull Larus audouinii in Sicily, characteristics and its origin
Avocetta, 2016 The Audouin’s Gull Larus audouinii Payraudeau, 1826 has never been recorded breeding in Sicily: the authors are here reporting the discovery of a breeding colony on the island of Vendicari, province of Siracusa, off the south-east coast of Sicily.

Animal Conservation, EarlyView.Rapid assessment of the delayed impacts of fires on endangered species is essential for accurately guiding conservation efforts. After the fire, surviving Hermann's tortoises (Testudo hermanni) showed only minor behavior alterations, and burnt habitats continued to provide them with essential resources.

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Population Change in a Marine Bird Colony is Driven By Changes in Recruitment
Avian Conservation and Ecology, 2011 The population dynamics of long-lived birds are thought to be very sensitive to changes in adult survival. However, where natal philopatry is low, recruitment from the larger metapopulation may have the strongest effect on population growth rate even in

Integrating migratory connectivity data into the conservation of Australian sharks and rays
Conservation Biology, EarlyView.Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.

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.

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 ...

Ethology, EarlyView.This conceptual figure uses Directed Acyclic Graphs (DAG) to represent the hypothesized biological mechanism in which age and/or plumage traits affect reproductive success, and social interactions mediate these relationships. It highlights the predicted decomposition of (a) the total effect into the direct and indirect effects under scenarios of (b ...
