From the animal's perspective, most of these daily interactions are likely to have positive outcomes. With consistent and reliable interactions, a human–animal relationship is expected to develop. Our aim of this study was to investigate if the presence of the primary keeper in the public viewing area of zoo exhibits impacts the behavior of animals. We observed the behavior of 15 individuals of six species in the presence and absence of their primary keeper. Overall, we observed animals being more active in their keeper's presence than when the keeper was not present. When we considered if the keeper was nearby around times of offered opportunities to animals (e.g., feeding, enrichment, and training), our results showed that animals were equally as active when the keeper was present before an opportunity and when no opportunity was offered. These equal activity levels imply that the keeper is a cue for a forthcoming event to the animals, which reflects anticipatory behavior. Overall, we demonstrate that keeper presence is an environmental context in which animals behave differently than in keeper absence.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":"55 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140602136","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}

As a result, studying behavioral development of cubs at the denning site has been difficult and unreliable. Although care staff at zoological institutions have easier access to animals, every effort is made to minimize intrusions to maternal groups, which presents research limitations. Detroit Zoological Society staff used audio-equipped cameras installed in behind-the-scenes spaces to conduct approximately 9 weeks of monitoring on two female polar bear cubs of the same litter, one of whom (Laerke) was hand-reared while the other (Astra) was mother-reared. Monitoring spanned ages 14-24 weeks and consisted of 12, 5-min focal observations per observation day timed to evenly cover the entire 24-h day. Using generalized linear mixed models, we examined relationships between behavior and time of day, hour, and age. We also conducted descriptive analyses and used these to draw comparisons between the two cubs where appropriate. Despite different rearing environments, both cubs had highly comparable patterns of inactive, locomotory, and independent play behaviors. Astra generally decreased time spent nursing and in proximity to Suka as she aged. Data presented here represent a continuation of previous neonatal observations conducted on Astra, adding to the minimal body of knowledge currently available on first year polar bear cub development. We also report successful mitigation of stereotypic behavior in Laerke. Further studies of captive maternal groups can provide insight into this critical developmental stage, supporting both captive-based breeding efforts and in situ conservation efforts.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"149-163"},"PeriodicalIF":1.3,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139425619","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}

Captive breeding and reintroduction of zoo-bred hatchlings has been successful, however, limited founders in the captive population and the inability to bring new, wild genes into the captive colony presents a major concern for the conservation of this species. The use of artificial insemination (AI) was first applied to snakes in the 1980s but further development of the technique has since received little attention. Our goal was to develop a method of AI for use in breeding Louisiana pinesnakes to facilitate gene flow from wild to captive populations. We inseminated two captive Louisiana pinesnakes with semen collected from one donor male, novel to both females. Timing of AI occurred following the emergence of females from brumation, and when large, distinct follicles were detected using digital palpation. Females were inseminated four and five times over a period of 14 and 19 days, respectively, using fresh and 2-day refrigerator stored semen. One female laid seven eggs, which resulted in four fertile eggs and two viable hatchlings, while the second female produced three fertile of seven eggs laid but no viable hatchlings. Genetic analyses confirmed the donor male was the sire of hatchlings. This is the first successful AI of an endangered snake species and provides a framework for the use and optimization of assisted reproductive technologies for use in conservation breeding programs.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"178-182"},"PeriodicalIF":1.3,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139486506","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}

The aquarists of Planet Ocean Montpellier (POM, France) have bred H. colliei for 15 years and recorded parameters suitable for this species' successful embryonic and post-embryonic development. POM aquarists now regularly record egg-laying events of H. colliei and use four tanks to incubate eggs and raise neonates, late hatchlings, early and intermediate juveniles, subadults, and sexually mature specimens. In this work we provide the first long-term biometric data on H. colliei from the hatchling to the subadult stage. We also report the biotic and abiotic parameters sufficient to breed H. colliei in aquaria. We finally describe the methods used to facilitate individual monitoring of specimens along the ontogeny and several pathologies identified in this species, their putative causes, and the corresponding treatments.

To better understand the relationship between pacing and conspecific visual contact, we investigated this effect by conducting a barrier experiment on a male-female pair of Sumatran tigers (Panthera tigris sumatrae) in Rotterdam Zoo, the Netherlands. The tigers were exposed to four consecutive housing treatments: (i) housed in the same enclosure (baseline), (ii) housed in separate enclosures with visual contact, (iii) housed in separate enclosures without visual contact, and (iv) housed in the same enclosure after the separation. We used focal and scan sampling to measure pacing and recorded the number of visitors. Moreover, we applied scan sampling to measure activity. Overall, our results indicate that the tigers paced significantly more when housed in separate enclosures with conspecific visual contact.

An insect of increasing commercial importance is the king worm (Zophobas morio), a type of darkling beetle larvae. The initial objective of this study was to determine if prolonged exposure to isoflurane would lengthen anesthetic recovery and lead to euthanasia. Larvae were exposed to isoflurane for 10 min, 40 min, 70 min, 190 min, 13 h, and 24 h (n = 10 for each treatment duration group), and time to recovery was subsequently monitored in room air. The second objective was to determine effectiveness of secondary euthanasia methods: injectable potassium chloride at 1 mg/g body weight (n = 5) and 3 mg/g body weight (n = 5) doses; immersion in 200 proof ethanol (n = 10), 10% buffered formalin (n = 10), and water (n = 10); and freezing at -18°C (n = 10). Prolonged exposure to isoflurane led to extended recovery times, but 100% mortality was not achieved. Submersion in ethanol and injection of potassium chloride at a 3 mg/g body weight dose resulted in 100% mortality.

Like most vertebrates, frogs cannot synthesize carotenoids and must therefore obtain these essential nutrients through diet. It is unclear if amphibians can cleave provitamin A carotenoids to form vitamin A metabolically within the body, so common practice is to supplement their captive diets with both preformed vitamin A and provitamin A carotenoids. We carried out a feeding experiment in tadpoles of Phyllobates vittatus, a commonly kept poison frog species, to test the effects of supplementing a fish flake diet with a provitamin A carotenoid (2.5 mg/g β-carotene) and vitamin A (0.033-0.066 µg/mL retinyl acetate), both individually and in combination. Contrary to our expectations, supplementation had either no effect or adverse effects on tadpole growth and survivorship. Tadpoles reared under supplemented diets with vitamin A showed higher mortality rates, coupled with symptoms of hypervitaminosis A. Survivors had a smaller body size and mass at metamorphosis. β-carotene supplementation alone had no detectable effect. The vitamin A and β-carotene levels in our supplemented diet have been shown to be harmless or benefit tadpoles of other species, yet our results indicate that adding these amounts to what is found in a generalist fish flake mix can have detrimental effects on P. vittatus tadpoles. More broadly, this study highlights the importance of creating husbandry guidelines based on the specific physiological needs of the species (or species groups) being kept in captivity, rather than general ones for all amphibians, as is often done.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"169-177"},"PeriodicalIF":1.3,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139571014","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}

This report describes telson avulsion in three Atlantic horseshoe crabs at a public aquarium and attempted external stabilization with a vascular silicone tie in two of three affected animals. The horseshoe crab that received no veterinary intervention suffered a complete telson amputation 1 month after the initial injury. Although the two other horseshoe crabs did well postoperatively, and external stabilization prevented further avulsion or amputation, they still could not right themselves if flipped into dorsal recumbency. All three horseshoe crabs were ultimately euthanized due to animal welfare concerns. To avoid potentially serious telson ligament injury, horseshoe crabs should never be picked up by the telson.
