%0 Journal Article %T The Different Physical and Behavioural Characteristics of Zoo Mammals That Influence Their Response to Visitors %A Marina B. Queiroz %J Archive of "Animals : an Open Access Journal from MDPI". %D 2018 %R 10.3390/ani8080139 %X Studies of the zoo visitor effect (changes in animal behaviour in response to the presence of the public) have had varying results: most studies have found that visitors have a negative animal welfare impact, but some studies have found no effect, or even, a positive effect on animal welfare. The problem is that most studies only consider one species at a time and meta-analyses suffer from the great variation in animal husbandry, enclosures and the public¡¯s behaviour. Therefore, we examined 17 different mammal species responses to zoo visitors over the period of one year. The species were chosen to show a variation in physical characteristics (e.g., body weight) and habits (e.g., diurnal or nocturnal); this allows us to determine which characteristics are important in determining the variation of the response of mammals to zoo visitors. The results showed no effect of body weight, but activity cycle was very important, with diurnal animals being more affected. These results allow us to predict which mammal species will be most negatively affected by zoo visitor presence %K animal welfare %K behaviour %K mammals %K zoo enclosures %K zoo public %K zoo visitors %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6115739/
