Previous research suggests a link between innovation rate, neophobia and behavioural flexibility in the field and in captivity. In this paper we examine three correlates of flexibility in five opportunistic avian species that feed together in Barbados: three Passeriformes (the Carib grackle, Quiscalus lugubris, the Lesser Antillean bullfinch, Loxigilla noctis, and the shiny cowbird, Molothrus b...

When brought into captivity, wild animals can adapt to domestication within 10 generations. Such adaptations may decrease fitness in natural conditions. Many selective pressures are disrupted in captivity, including social behavioral networks. Although lack of sociality in captivity appears to mediate domestication, the underlying mechanisms are not well understood. Additionally, determining th...

This study examined sleep histories associated with resilience after trauma defined as a continuous lack of psychiatric illness across 37 years. Data were drawn from a 37-year follow-up examination of the effects of the Vietnam prisoner of war (POW) experience. The Robert E. Mitchell Center for POW Studies is a unique institution holding the only longitudinal study of the effects of the America...

Examining the relevance of 'animal personality' involves linking consistent among- and within-individual behavioural variation to fitness in the wild. Studies aiming to do this typically assay personality in captivity and rely on the assumption that measures of traits in the laboratory reflect their expression in nature. We examined this rarely tested assumption by comparing laboratory and fiel...

Friendly postconflict (PC) interactions between former opponents have been described for a large number of primate species held in captivity. We investigated conflict management behaviour for wild Hanuman langurs, Semnopithecus (Presbytis) entellus entellus, in India, using a large sample of over 6000 agonistic and affinitive interactions recorded in one one-male/multifemale troop and three all...

This study builds on a continued effort to document potential long-term research impacts on the individual, as well as to identify potential markers of survival for use in a field framework. The Transient Juvenile Steller sea lion (TJ) project was developed as a novel framework to gain access to wild individuals. We used three analyses to evaluate and predict long-term survival in temporarily c...

The collared peccary (Tayassu tajacu) is widely distributed over the American continent, being found from the south of the USA to the north of Argentina. In Brazil, it is spread all over the country, being one of the potential species to be raised in captivity. Therefore, the cytogenetic techniques could be a potential tool for reproductive monitoring of animals raised in captivity, mainly when...

In 2008, Amanda Lindhout was kidnapped by a group of extremists while traveling as a freelance journalist in Somalia. She and a colleague were held captive for more than 15 months, released only after their families paid a ransom. In this interview, Amanda discusses her experiences in captivity and her ongoing recovery from this experience with Katherine Porterfield, Ph.D. a clinical psychologi...

Stress influences numerous psychological and physiological processes, and its effects have practical implications in a variety of professions and real-world activities. However, few studies have concurrently assessed multiple behavioral, hormonal, nutritional and heart-rate responses of humans to acute, severe stress. This investigation simultaneously assessed cognitive, affective, hormonal, an...

This review considers the study by A. Di Michele, professor at Free University of Bolzano (South Tyrol), dedicated to pre-war and military experience, as well experience captivity Italian-speaking soldiers Austro-Hungarian army during World War I. The main emphasis is placed on its role in process their ethno-cultural ethno-political self-identification, directly related population identity pol...
