Environmental enrichment and cognitive complexity in reptiles and amphibians: Concepts, review, and implications for captive populations

Reptiles and amphibians have been neglected in research on cognition, emotions, sociality, need for enriched and stimulating environments, and other topics that have been greatly emphasized in work on mammals and birds. This is also evident in the historic lack...

Enrichment object preferences in laboratory rhesus monkeys (Macaca mulatta)

To promote the psychological well-being of captive non-human primates, facilities develop and implement an environmental enhancement plan (Animal Welfare Act, Section 3.81). Enrichment options described in the plan should be selected to demonstrably promote species-typical behaviors. Too often, enrichment choices...

Social knowledge and signal in primates

Primates are notable for having a rich and detailed understanding of their social environment and there has been great interest in the evolution and function of social knowledge in primates. Indeed, primates have been shown to have impressive understandings of...

Pro-social behavior in rats is modulated by social experience

In mammals, helping is preferentially provided to members of one's own group. Yet, it remains unclear how social experience shapes pro-social motivation. We found that rats helped trapped strangers by releasing them from a restrainer, just as they did cagemates....

Behavioral management approach to facilitate use of pen-housed nonhuman primates for toxicology studies

Housing laboratory primates in large pens can improve welfare by providing ample opportunity to express normal social and locomotor behaviors. This type of housing, however, can present great challenges in terms of manipulating animals for study procedures. The use of...

Nest building and posture changes and activity budgets of gilts housed in pens and crates

The aim of the present work was to study nest building, posture changes and the overall activity budget of gilts in pens vs. crates. Twenty-three HB gilts (high piglet survival day 5) and 21 LB gilts (low piglet survival day...

The effects of environmental enrichment and age-related differences on inhibitory avoidance in Zebrafish (Danio rerio)

The inhibitory avoidance paradigm allows the study of mechanisms underlying learning and memory formation in zebrafish (Danio rerio Hamilton). For zebrafish, the physiology and behavior associated with this paradigm are as yet poorly understood. We therefore assessed the effects of...

Are 50-kHz calls used as play signals in the playful interaction of rats? I

During playful interactions, rats emit increased levels of 50-kHz vocalizations. It is possible that these vocalizations are used as play signals that promote and maintain playful contact. The study investigated this possibility. It was predicted that if these vocalizations are...

Responses by wild house mice (Mus musculus) to various stimuli in a novel environment

House mice (Mus musculus) pose a threat to the native flora and fauna on islands, and can cause significant damage wherever they have been introduced. Methods used to eradicate invasive rodents, like house mice, at high population densities may not...

The relationship of dominance, reproductive state and stress in female horses (Equus caballus)

Maintaining a dominant position in a hierarchy requires energetically expensive aggressive displays and physical exertion. Lab based winner–loser studies, often conducted with individuals from non-social species, have shown that subordinates have higher stress hormone levels than dominant individuals. However, in...
