Females typically produce two eggs per clutch with each season having one to four clutches per year. Egg production beyond the species' natural output can significantly impact an individual's health as significant amounts of calcium are required to form the eggshell. The objective was to evaluate the effectiveness of deslorelin acetate (Suprelorin) in suppressing gonadal function and egg production of a 39-year-old female white-naped crane with a history of long breeding seasons and excessive egg laying. Deslorelin acetate (9.4 mg) implants were administered s.q. at 1- or 3-month intervals over four breeding seasons. Fecal samples were collected 1-3 times/week and gonadal hormones were extracted and analyzed. Egg production was recorded. Analysis showed that deslorelin acetate (9.4 mg) implanted s.q. twice at a 3-month interval beginning at the expected start of the breeding season was not fully effective in suppressing gonadal function and egg production. The following breeding season, three deslorelin acetate 9.4 mg implants were administered at ~1-month intervals beginning at the expected start of the breeding season. This protocol was more effective at suppressing gonadal hormone production and egg production. Our results demonstrate a timeseries of how deslorelin acetate impacts reproductive function in white-naped cranes, though further studies should include the effects of implant after cessation.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"208-215"},"PeriodicalIF":1.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145551352","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, the management of mature male elephants poses distinct challenges for both population sustainability and animal wellbeing. Identifying the goals and challenges of institutional members as they relate to male elephant management will inevitably aide in the planning of future management strategies and identify areas for collaboration with other ex-situ elephant populations. The purposes of this study were (1) to survey EAZA facilities housing adult male elephants to understand institutional priorities around musth management, male socialization, and semen collection to compare them to population-wide recommendations; and (2) to compare patterns to those obtained from a recent survey of Association of Zoos and Aquariums (AZA) accredited facilities. We received responses from 55 facilities, holding 76 adult male elephants. The highest priorities were natural breeding and male socialization; assisted reproductive techniques (e.g., semen collection) were not prioritized at the institutional level, despite emphasis by the EEPs. Further, while most facilities acknowledged the importance of managing elephants around musth, few had formalized monitoring programs. Compared to AZA institutions, EAZA facilities had similar goals and challenges, with lower reliance on and capacity for collecting semen. These results underscore the specialized care that male elephants require to achieve population sustainability and uphold high animal welfare standards, with clear opportunities for knowledge sharing with AZA counterparts.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"124-137"},"PeriodicalIF":1.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145356124","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}

While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

In this study, we employed a next generation sequencing strategy to develop a new set of primers for microsatellite regions specific to the Harpy Eagle. These markers were validated in Harpy Eagle individuals maintained in captivity at Brazilian zoos and conservation institutions. We characterized these captive individuals using ten highly polymorphic microsatellite loci to estimate relatedness and individual identification at > 95% accuracy. The same effect can be achieved with four loci. Additionally, we developed a statistical test to further refine relationship estimates. Paired with robust sex markers, the new set of microsatellite markers presented here the potential to guide ex situ management strategies, aiming for better reproductive pairings and the maintenance of genetic diversity of the Harpy Eagle.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"97-108"},"PeriodicalIF":1.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13051753/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145253077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the impact of specific messaging and terminology used in educational signage and programs remains unclear. The goal of the current studies was to examine the favorability and impact of common terminology around the topics of animal care and welfare used within zoos and aquariums. Participants were randomly selected from Brookfield Zoo Chicago's household member database and invited via email to complete a brief survey. Study 1 employed a feeling thermometer to assess the favorability of common zoological terms. Studies 2-7 utilized vignettes to examine terminology through both feeling thermometers and Likert-type scales, measuring both favorability and visitor perceptions of animal care and welfare. Results from Study 1 suggest that there are some statistically more favorable terms that zoological facilities could use when interpreting different topics for visitors. These include professional care, habitat, animal health, veterinary care, animal care specialist, and animal care professional. However, Studies 2-7 demonstrated that when comparing the terms within contextual vignettes, the significant differences in favorability no longer existed. Results can be utilized by practitioners in zoos and aquariums to choose more favorable terms when discussing animal care and welfare. Only through sound science will we better understand how best to impact zoo and aquarium visitors' perceptions of animal welfare.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"185-194"},"PeriodicalIF":1.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145670129","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}

In their native tropical habitat, wild lions are primarily nocturnal, capitalizing on cooler temperatures and darkness for effective hunting and minimizing thermoregulation stress. By extension, their territorial behaviors, notably the striking vocal advertising known as \"roaring,\" are predominantly nocturnal. However, atypical diurnal territorial activity has been reported for captive lions in some captive settings, including Fota Wildlife Park (FWP) in Ireland. This study investigates the influence of seasonal weather conditions on the temporal distribution patterns of territorial vocalizations by a pride of captive Asiatic lions living at high latitudes in FWP, where extended audio recordings were regularly made from mid-summer to mid-winter 2021. Consistent with typical behaviors of their wild counterparts in the tropics, the captive lions at FWP exhibited persistent crepuscular peaks of roaring activity throughout the study. However, as the seasons passed, these peaks of roaring activity immediately after sunset and, to a lesser extent, just before dawn clearly followed the substantial seasonal changes in the timing of these two daily synchronizing stimuli at such high latitude. While most roaring activity occurred during the hours of darkness, consistent with prior observations at FWP during the winter, they nevertheless also roared at all hours of the day throughout all seasons, including the summer months. Persistent daytime territorial vocalizations in captive settings are therefore probably more likely related to environmental factors other than cool weather in this temperate captive setting.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"154-162"},"PeriodicalIF":1.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145453359","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}

Previous reports indicated that BR in zoos often receive diets with a higher proportion of easily digestible compounds compared to other rhino species. Additionally, BR are susceptible to iron overload disorder (IOD). We compared the feeding methods and recommendations, and sampled diets and feces of 117 WR and 82 BR across 41 European zoos. The few available data for free-ranging animals were also incorporated. The percentage of forage in the total estimated dry matter intake was 93% for WR and 77% for BR, matching fecal parameters indicating a higher diet digestibility in BR. BR received higher levels of (pelleted) compound feeds and produce than WR. Nevertheless, dietary fiber levels were similar to that reported for free-ranging specimens in both species. Zoo diets were higher in several minerals (Na, P, Cu, Zn) than natural diets. However, zoo BR received diets with similar iron content to that described in free-ranging BR diet items and fecal iron levels were not higher than those in the few samples of free-ranging BR available, suggesting that iron levels in zoo BR diets are not overly excessive. Consequently, IOD appears to be more complex, associated with iron bioavailability and possibly non-dietary causes. Grass hay was used in 100% of WR and 36% of BR (all BR facilities used lucerne hay). BR feces had levels of abrasive silica comparable to those of free-ranging WR and much higher than free-ranging BR, matching reports of excessive tooth wear in adult BR. Browse provision for BR could not be quantified but appeared low in general; no alternative forages (like sainfoin) were fed. Efforts to consistently provide high amounts of browse to BR must be increased and forage should be low in iron and abrasive silica.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"109-123"},"PeriodicalIF":1.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13051751/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145276015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence of the impacts on animal welfare or visitor education is limited. Red panda (Ailurus Fulgens spp.) encounters are gaining popularity despite a lack of research on their effects. As red panda are a characteristically cautious species and prone to disturbance, concern has been raised as to their suitability for encounters. We examined the extent and composition of red panda encounters amongst 150 Global Species Management Plan (GSMP) member zoos (survey responses), and their impact on longevity and reproduction (species 360 analysis). Over a third (39%) of zoos surveyed offered red panda encounters, with most (71%) being animal feeding experiences. Educational information was provided in almost all cases (95%) and focused on the encounter individuals and species' natural history. Of the 31 encounter red panda who were also part of a breeding program, 24 reproduced. Comparative data analysis suggested that encounter red panda produced more offspring and had higher longevity (survival) than non-encounter individuals, although this may reflect changes in red panda husbandry over time. A. f. styani were less likely to breed and produced fewer offspring than A. f. fulgens. Whilst there appears to be no major negative impacts of red panda encounters, continued monitoring and ensuring high animal-welfare standards remains vital.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"163-177"},"PeriodicalIF":1.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13051758/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145565475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
