Human–animal interaction (HAI) can be valuable for captive animals, and many zoo-housed species benefit from interactions with their keepers. There is also an increasing body of evidence that some animal species possess personalities that are temporally consistent. However, the majority of zoo research, particularly on personality and HAI, traditio...
Article
Full-text available
Mangroves form coastal tropical forests in the intertidal zone and are an important component of shoreline protection. In comparison to other tropical forests, mangrove stands are thought to have relatively low genetic diversity with population genetic structure gradually increasing with distance along a coastline. We conducted genetic analyses of...
Article
Personality has been researched in many companion animals and is described as differences in behavioural traits of individuals that often remain consistent over time. In domestic cats many factors have been discovered to influence personality, including breed, coat colour, gender, rearing experience, number of cats within a household, owner age, ow...
Article
