Getting It Straight: Accommodating Rectilinear Behavior in Captive Snakes—A Review of Recommendations and Their Evidence Base
Snakes are sentient animals and should be subject to the accepted general welfare principles of other species. However, they are also the only vertebrates commonly housed in conditions that prevent them from adopting rectilinear behavior (ability to fully stretch out). To assess the evidence bases for historical and current guidance on snake spatial considerations, we […]
A comparative approach to the study of Keeper–Animal Relationships in the zoo
Abstract 10.1002/zoo.20289.abs Research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal’s fear of humans, can markedly limit the productivity and welfare of farm animals. This article begins to explore some of the factors that need to be considered to investigate Keeper–Animal Relationships (KARs) in the […]
The behavioral context of visual displays in common marmosets (Callithrix jacchus)
Communication is important in social species, and may occur with the use of visual, olfactory or auditory signals. However, visual communication may be hampered in species that are arboreal have elaborate facial coloring and live in small groups. The common marmoset fits these criteria and may have limited visual communication. Nonetheless, some (contradictive) propositions concerning […]
