Managing the Socialization of an Adult Male Gorilla (Gorilla gorilla gorilla) With a History of Social Deprivation

Most non-human primates exhibit aggression during changes in social group composition. In zoological parks, group membership changes are necessary for optimal population management, but can elicit problematic aggression. Furthermore, some primates with a long history of social deprivation are hyperaggressive when introduced to conspecifics. In this study of one male gorilla with a 30-year history […]

Effects of hand-rearing on the reproductive success of western lowland gorillas in North America

This study sought to assess the potential effects of hand-rearing by evaluating the relationships among rearing type and reproductive success in the American Zoo and Aquarium Association’s Species Survival Plan® for western lowland gorillas. Our study included data on 697 gorillas: 257 wild-born (WB) and 440 born at zoos or related facilities in North America. […]

Early social influence on nestling development in Waldrapp ibis (Geronticus eremita)

Abstract 10.1002/zoo.10050.abs The Waldrapp ibis is critically endangered; hence specific knowledge is needed to support the management of the last birds in the wild, and to prepare for reintroduction projects. In this study we attempted to test the effects of raising an ibis as a single chick from hatching to the age of 3 weeks, […]

Use of positive reinforcement training in the management of species for reproduction

Abstract 10.1002/zoo.1430130509.abs Positive reinforcement training holds great potential for enhancing the management of species for reproduction. This paper reviews a wide range of animal training activities and resultant benefits which could have application to captive reproduction programs. Recognized benefits fall into several categories. Basic animal care can be improved through voluntary cooperation by the animals […]

Socialization and Stress in Cats (felis Silvestris Catus) Housed Singly and in Groups in Animal Shelters

Single- and group-housing conditions for cats in animal shelters represent spatially and socially very different housing types. This study investigated whether the socialization of the cat towards conspecifics and people influences adaptation to these two housing types. Socialization towards conspecifics and people was determined in 169 rescued cats by means of two behavioural tests and […]

Differences Between Vocalization Evoked by Social Stimuli in Feral Cats and House Cats

To investigate how socialization can affect the types and characteristics of vocalization produced by cats, feral cats (n=25) and house cats (n=13) were used as subjects, allowing a comparison between cats socialized to people and non-socialized cats. To record vocalization and assess the cats’ responses to behavioural stimuli, five test situations were used: approach by […]

Wolf socialization- A study of temperament in a wild social species

A detailed analysis was made of the process by which the wolf comes from a state of unfamiliarity and fear of humans to a state of familiarity and friendliness. The nature of the process was found to depend on the age of the animal as well as the technique employed by the experimenter. Although young […]

Comparison of two introduction methods for african elephants (Loxodonta africana)

Managers must consider an animal’s potential for aggression when they decide to change or form a captive social group formation. In this study we compared two introduction methods (termed ‘‘sequential’’ and ‘‘nonsequential’’ introduc-tions) in African elephants to assess their effectiveness in managing aggression and minimizing stress. Both introduction methods included four phases: baseline, visual contact, […]

The effects of social interaction and environmental enrichment on the space use, behaviour and stress of owned housecats facing a novel environment

Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is a need to develop appropriate strategies to reduce these effects. Here, we investigated the effect of physical (inclusion of different […]

Development of sociality and emergence of independence in a killer whale (Orcinus orca) calf from birth to 36 months

Dolphin calves spend most of their time swimming with their mother immediately after birth. As they mature, the calves become increasingly independent, and begin to interact more often with other calves, juveniles, and sub-adults. For bottlenose dolphin calves, sociality is related to maternal behaviors. Unfortunately, much less is known about the development of sociality and […]
