Syllables function as the building blocks of birdsong, so changes to their production will have implications for overall song structure. It is well established that anthropogenic disturbance can influence syllable production in wild songbird populations, but the effect of anthropogenic disturbance on syllable production in ex situ populations has not been studied. We set out to fill this gap by comparing the syllable production of Chester Zoo's Bali myna (Leucopsar rothschildi) population during a period of zoo closure in 2020 (due to the COVID-19 lockdown) to a period of normal zoo opening in 2019. The number of syllables per song, the rate at which syllables were produced and the diversity of syllables all showed evidence of plasticity across days and years. However, only the number of syllables per song responded significantly to anthropogenic disturbance. Changes in syllable number due to anthropogenic disturbance could mitigate potential signal masking from unpredictable noise, although communication efficacy may still be affected. As a result, changes in vocal communication could impact conservation breeding programmes by altering the way that individuals interact with conspecifics.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is little known on the outcomes of these complimentary materials, despite the opportunity to measure direct conservation action. Six public outreach events hosted by Oklahoma City Zoo occurred from 2016 to 2023. Participants at each event were invited to pledge to plant monarch habitat and in exchange received complimentary materials. Participants were surveyed 2-3 months post-event to follow-up on outcomes of materials distributed as well as measure monarch butterfly knowledge post-event. Visitors reported planting milkweed plants at higher rates than seeds and visitors' post-event knowledge of monarchs was high. This study demonstrates that overall return on investment, measured by pro-environmental behavior, is lower when purchasing seeds compared to purchasing milkweed plants. Overall, outreach programs that distribute complimentary seeds/plants have the potential to create habitat and create positive conservation action outcomes.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145207867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stereotypies present themselves in many different forms, dependent on the biology of a species, internal and external motivational factors, individual animals' history, and early development. In the case of giraffes, a popular and charismatic species found in zoos, stereotypies concerning the mouth and tongue - oral stereotypies - are especially prevalent. Various hypotheses have been developed in tandem with the observation of giraffe oral stereotypies, mostly surrounding their motivations pertaining to food acquisition. Such hypotheses suggest that oral stereotypies persist due to (1) unfulfilled natural feeding behaviors, (2) nutritional and behavioral discrepancies in food presentation, and/or (3) an imbalance between concentrate grain and dietary fiber. Findings from recent literature suggest that the implementation of complex feeders, increased browse allotment, and a diet that is overall more closely representative of what wild giraffes receive has helped to decrease instances of oral stereotypy. An integrative approach employing each of these hypotheses is recommended to address the multifaceted mechanisms that may underly giraffe oral stereotypy. The most recent studies in this area have already begun to incorporate such approaches, and future studies would benefit from the continued consideration of multiple motivational factors when addressing oral stereotypy in zoo-housed giraffes.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crocodile behavior was monitored over 95 observation hours, split approximately equally between transparent water and opaque water conditions. In addition to agonism rates, the crocodiles' use of water was evaluated to ensure the change in their habitat did not disrupt utilization of the water, which is an important component of their thermoregulatory processes. Agonism rates were approximately equal between the transparent and opaque water conditions. The proportion of the group in water was lower in the opaque condition though the mean difference between conditions suggests that approximately two more crocodiles (out of a group size that ranged from 21 to 18 individuals) were in water in the transparent condition than opaque condition. Overall, these findings suggest the opaque water had little to no effect on the crocodiles' behavior as measured here. However, the opaque water may have increased environmental complexity. In nature, crocodiles navigate opaque water utilizing chemosensory and integumentary sensory modalities that are likely underutilized in transparent water commonly provided to crocodilians living in human care. Further research is needed to understand how opaque water may be enriching for crocodilians.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144971950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, changes in the social environment may also represent a stressor leading to changes in glucocorticoids-hormones responsible for maintaining homeostasis under stressful conditions. We studied glucocorticoids in captive bonobos (Pan paniscus), a social species of great ape with a complex social organization. We monitored bonobos in captivity before, during, and after a change occurred in their social environment; when a new group member was introduced at the facility. We repeatedly measured individuals' cortisol (corrected for creatinine, or variation in the concentration of samples) from urine samples and found individuals of the established group did not change in cortisol during or following their introduction to a novel bonobo individual. The emigrating bonobo, however, had elevated cortisol upon arrival which decreased as she was introduced to each existing bonobo at the facility. These results suggested that the new individual may have experienced stronger stressors relative to resident individuals during this captive introduction. We recommend based on the results from this study, that social animals be introduced to new group members carefully, and to avoid prolonged social isolation for new animals. When changes in social dynamics are driven by human caretakers rather than initiated by the animals themselves, care should be taken to mimic natural dispersal patterns when possible.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144972025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No mortality was observed during the feeding trial of leatherback sea turtles. Significant improvements (p < 0.05) in growth and feed utilization were observed in the 4G and 6G groups.

Turtles in the 4G group had the highest activities of fecal pepsin and lipase (p < 0.05) while other digestive enzyme activities were maintained (trypsin, chymotrypsin, and amylase). Also, this group of turtles showed better nutrient bioavailability, as evidenced by the peaks and thermal characteristics observed in thermograms of fecal matter.

Diet is a well-established driver of gut microbiome structure and function, and formulating nutritionally balanced diets is vital to ex situ animal care and management. Prebiotic dietary items can promote beneficial microbial communities in the guts of ex situ wildlife. Animal fibers (skin, hair, and connective tissue) can act as prebiotics for carnivores, influencing gut microbiome structure and function. Social interactions and differing environmental exposures can further shape animal microbiomes, with evidence of group and environmental signatures in the microbiomes of some social species. To test for respective patterns of diet and social group, we used 16S rRNA sequencing to track the gut microbiomes of two groups of African painted dogs (Lycaon pictus) housed at the Cincinnati Zoo & Botanical Garden. The diet of one group was shifted to include increased whole prey (e.g., rabbits), representing an uptick in animal fiber intake. We found that, despite both groups sharing a diverse set of core microbes, there were distinct group signatures in the dogs' microbiomes, a pattern that grew stronger over time. Furthermore, although the diversity of gut bacteria showed minimal variation between groups and over time, the overall microbial composition and the abundance of specific taxa varied significantly between groups and with increased dietary whole prey. The results of this study further demonstrate the value of zoo populations for understanding the factors that drive animal microbiome structure and highlight the influence of management decisions in shifting animal microbiomes.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144849195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
