Japanese macaque societies are characterized by frequent intragroup conflict both in free-ranging and zoo-housed conditions. In zoos, understanding the factors that contribute to wounding is of interest because this knowledge can aid in proactive husbandry and management planning that can minimize the negative impacts wounding can have on individual welfare. This study sought to determine whether the variables sex, season and age predicted wounding rates. Data were collected for 24 months on 119 Japanese macaques living in 10 zoos, and we analyzed the contribution of variables using generalized linear mixed models. A total of 1,007 wounds were reported, and the best model included the interaction between sex and season. Follow-up analyses revealed that females incurred more wounds than males, and this sex difference was more pronounced during the breeding compared to the nonbreeding season. On average, individuals received 4.67 (±SEM: 0.55) wounds per year and 77.31% of the population incurred at least one wound in the study period.The majority of wounds were superficial and did not require veterinary intervention.Wound locations were not randomly distributed across body regions and were most often reported on the face. Finally, macaques living in larger social groups experienced more wounds, on average. This study represents the first quantification of wounding in this species and may provide insight to help inform husbandry and management strategies in zoos.

Prolonged stress responses can lead to infertility and death; therefore monitoring respective indicators like stress-related hormones and behaviors is an important tool in ensuring the health and well-being among zoo-housed animal populations. Changes in social structure, such as the introduction of a new conspecific, can be a source of stress. In April 2010, a sexually mature female western lowland gorilla (Gorilla gorilla gorilla) was brought to Lincoln Park Zoo (LPZ; Chicago, IL) from the Chicago Zoological Park (Brookfield, IL) for a breeding recommendation from the Gorilla Species Survival Plan. Fecal glucocorticoid metabolites (FGMs) were monitored in two gorillas prior to, during and immediately following the social introduction. Reproduction events, such ovarian cyclicity and pregnancy, were monitored using behavior and fecal progestagen metabolite (FPM; female) and fecal androgen metabolite (FAM; male) analyses. Mean (± standard error) FGM concentrations for the male were elevated (P = 0.002) during the introduction (20.61 ± 0.83 ng/g) compared to the pre- and post-introduction phases (11.31 ± 0.48 ng/g and 12.42 ± 0.65 ng/g, respectively). For the female, mean FGM concentrations were lower (P < 0.001) during the post-introduction (17.91 ± 1.07 ng/g) than during the pre- and introduction phases (30.50 ± 3.42 and 27.38 ± 1.51 ng/g, respectively). The female maintained normal FPM cyclicity throughout the study and became pregnant in the post-introduction phase. These results suggest the importance of both behavioral and physiological monitoring of zoo animals and demonstrate the potential stress that can occur during social introductions.

Many modern zoos strive to create connections between guests and animals through animal visitor interaction (AVI) programs. However, there has been relatively little research into the effect of AVI programs on the welfare of program animals. Previous research has revealed three factors that may affect AVI program animal welfare: species differences, handling and transport, and the provision of choice and control. We assessed the effects of an AVI program designed with these factors in mind on the behavior of a flock (N = 16) of zoo-housed domestic chickens (Gallus gallus). Behavioral data were collected on program days and on non-program (control) days, and we considered the time leading up to the program, the program itself, and the time immediately following the program. When comparing flock behavior on program days to control days, we found no differences in behavioral indicators of welfare during the time leading up to the program and during the program. Rates of aggression, however, were significantly greater after the program had concluded compared to the same time period on matched control days, but still occurred infrequently. Additionally, we recorded the spatial location of each animal while the program occurred and found that the chickens did not spend significantly more or less time in the feeding zone as visitor participation increased, although there were individual differences within the flock. We conclude that the relatively small behavioral changes seen were not indicative of a change in welfare and consider those results in the context of the program design.

People’s attitudes toward wildlife may impact their behaviors in support of conservation. We surveyed people in the United States to determine if gender, age, or visual contexts commonly seen in zoos impacted wildlife attitudes and perceptions of animals in zoos. After viewing an image of a two-toed sloth (Choloepus hoffmanni) or reticulated python (Malayopython reticulatus) in one of six different contexts, respondents indicated their agreement with statements designed to reveal their wildlife attitudes. We categorized attitude types, determined factors influencing attitudes, and investigated perceptions of animals in zoos. Analyses revealed both positive and negative wildlife attitudes. Attitudes were not influenced by the context in which animals were portrayed but were highly impacted by gender and age. Similar factors influenced perceptions of animals in zoos. Zoological facilities should consider how attitudes are shaped by gender and age when designing animal exhibits, educational programs, and media offerings to promote conservation mindedness.

The trade and private ownership of non-domesticated animals has detrimental effects on individual animals and their wild populations. Therefore, there is a need to understand the conditions that motivate and dissuade interest in non-domesticated pet ownership. Past research has demonstrated that the way in which non-domesticated animals are portrayed in images influences the public’s perception that they are suitable as pets. We conducted an online survey of people residing in the United States to investigate how viewing images that could be realistically captured in the zoo and broader tourism industries impact the degree to which people report interest in having that animal as a pet. We focused on two species, reticulated pythons (Malayopython reticulatus) and two-toed sloths (Choloepus hoffmanni), and presented each species in six different visual contexts. After viewing an image, respondents reported interest in pet ownership on a four-point Likert scale. Each species was studied separately in a between-subjects design and results were analyzed using ordinal logistic regression models. Thirty-nine percent of respondents reported interest in sloth pet ownership, and 21% reported interest in python pet ownership. However, contrary to our hypotheses, we found that viewing these species in different visual contexts did not significantly affect survey respondents’ reported interest in having either species as a pet. Generation was a significant predictor of interest in both sloth and python pet ownership, with younger generations reporting more interest in having these species as pets. Male respondents reported more interest in python pet ownership, whereas there were no significant differences between genders regarding interest in sloth ownership. We consider how modern media exposure to animals in unnatural contexts may relate to the generational effect and discuss priorities for future research to better understand the development of individual interests in non-domesticated pet ownership.
