The Johannesburg Zoo's Amphibian Research Project breeds H. pickersgilli for release to the wild. This study aimed to determine if hatching plasticity occurs in this species in relation to direct disturbance of clutches by water spray, misting the containers housing the clutches to maintain the relative humidity above 75% is essential husbandry. Several clutches were assigned to either an undisturbed group or a disturbed group. Tadpoles from clutches mist-sprayed with reverse osmosis water on day 4 after oviposition hatched at a younger age than from undisturbed clutches. The disturbed H. pickersgilli tadpoles began hatching on average 10 s after the introduced disturbance on day 4 from the point of being laid, when the tadpoles were at Gosner stage 21 and still had yoke sacs attached, whereas the undisturbed developing embryos hatched at 6.6 days on average at Gosner stage 21 but when many of the tadpoles did not have yoke sacs attached. The proportion of the embryos that hatched did not differ significantly between the undisturbed clutches and the disturbed clutches. Tadpoles hatching from H. pickersgilli clutches with no direct disturbance had a greater survival rate at 30 days after hatching and therefore an increased likelihood of survival than tadpoles from disturbed clutches. Maintaining clutches undisturbed by essential husbandry methods is preferable in H. pickersgilli ex situ breeding programs.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144971970","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}

After visual and physical barriers were unsuccessful at reducing these behaviors, he was prescribed anxiolytic medication. Our objective was to understand the effects of visitors on this male after reaching a therapeutic dose of anxiolytic medication. We analyzed effects of visitor presence (whether the exhibit was open or closed to the public) and number (weekdays vs. weekends, gate count). Behavior and physiological biomarkers were analyzed using linear and generalized linear models, respectively. Behaviors included time spent engaged in vigilance as well as rates of fast locomotion displays, leaping-and-hitting the barrier, grimacing, and rough scratching. Biomarkers included cortisol, dehydroepiandrosterone-sulfate (DHEA-S), the cortisol/DHEA-S ratio, testosterone, and immunoglobulin A (IgA). The langur performed more leap-and-hit barrier when the exhibit was open (β = 0.750, SE = 0.282, p = 0.013), on weekends (β = 0.618, SE = 0.277, p = 0.034), and with higher gate counts (β < 0.001, SE < 0.001, p = 0.004). Initially positive associations between rough scratching and visitor number were not significant when accounting for temperature. Cortisol/DHEA-S ratios trended toward significantly lower when the exhibit was open and IgA showed evidence of a potential dither effect, although the latter is ambiguous. No other behaviors or biomarkers were associated with visitor-related variables. We also compared behavior and physiology before and during anxiolytic medication as well as relationships between behaviors and biomarkers. Taken together, the balance of visitor effects appears neutral. Furthermore, considering other evidence, the langur does not appear to have diminished well-being.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144733631","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 Eastern Massasauga (Sistrurus catenatus) is a small rattlesnake with an ex situ breeding program maintained by a consortium of conservation breeding centres. Small population size in human care has restricted the supply of animals for in situ conservation, thus, the development of improved ex situ breeding protocols was recommended. The objectives of our retrospective study were to (1) describe and compare reproductive traits between two groups of Massasauga litters born in human care: wild-bred litters (i.e., conceived in the wild) and zoo-bred litters, (2) test for factors associated with improved reproductive output in zoo-bred litters, and, (3) make recommendations for standardizing ex situ breeding protocols. Data were collected on Massasauga birth events that occurred from 2000 to 2020 at 13 North American zoos and partner facilities. Six outcomes related to litter size and survival of offspring were compared between zoo-bred (n = 43) and wild-bred litters (n = 51). Odds ratios were used to test for correlations between nine predictor variables and four response variables in zoo-bred litters. We found higher mean litter size and number of live young per litter in wild-bred litters (12 and 10, respectively) compared to zoo-bred litters (6 and 2). Wild-bred litters more often contained live young and less often contained unfertilized ova (98% and 34% of litters, respectively) than did zoo-bred litters (58% and 81%). Experimentation on the effectiveness of alternative mating practices is warranted to improve reproductive output in human care, thereby increasing capacity to support in situ conservation.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144733630","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}

It is common practice to house snakes in enclosures on paper substrate, particularly when off-exhibit. We investigated the impacts of substrate provision (mulch or newspaper) and associated cleaning practices on nine long-nosed viper (Vipera ammodytes meridionalis) clutch mates over a 3-year period. We assessed health parameters, food consumption, growth, fecal and shed quality, and glucocorticoids in feces and shed skin. Snakes housed on newspaper were less likely to eat, had lower fecal quality, and demonstrated higher fecal and shed glucocorticoids; no other treatment effects were observed. Male snakes had higher fecal and shed glucocorticoids, and were more likely to defecate, had higher defecation counts, and had shorter inter-defecation intervals compared to females. Enclosures with a mulch substrate were significantly more humid than those with a newspaper substrate; enclosure temperature did not vary with substrate. We suggest differences in snakes by treatment are due to a combination of lower humidity offered by newspaper substrate and more frequent changing of newspaper substrate, which depletes the scent cues deposited by the enclosure occupant, creating more physiological arousal and potentially more stress when the animal is reintroduced to a less familiar enclosure. Our findings suggest that housing snakes on newspaper could have long-term fitness and health consequences.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144691717","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}

Weight gain and biometric parameters of 31 seahorses were weekly monitored for a period of 90-150 days. Additionally, histological analysis of organs of the digestive and reproductive tract was carried out to characterize and validate the scoring system, as well as a skin lipid profile evaluation as a measure of lipid mobilization. It is proposed that animals should be evaluated for abdominal muscle coverage, thoracic narrowing, contrast between the dorsal and abdominal region and muscle coverage between dorsal rings. We found significant differences between size and accumulation of fat in the liver as well as the degree of development of the gonads in the animals evaluated. Better energy reserves and reproductive potential are therefore expected for animals with a higher BCS. Our BCS methodology presents itself as an alternative of high practicality, simplicity and low cost, being an innovative tool for the evaluation of energy reserves in Syngnathids.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"360-370"},"PeriodicalIF":1.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144056441","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}

Considering that Bothrops species consume different diets in young and adults in the wild, we use B. jararacussu as a model to introduce other prey items in captivity. We use a generalized linear model (GLM) to understand if native and exotic anurans can be alternative items in the captivity diet of young and adult individuals. Our glm showed that snakes fed on bullfrog had less weight gain and consequently less growth than those provided with other diet groups.

One of the males observed was under treatment for arthritis, with additional treatments occurring during the study. Observation sessions were performed several times each day via single 1-min interval scans that recorded elevation status and whether subjects were active, recumbent, or standing still. All takins were observed climbing throughout the study, but repeated measures tests found no significant differences in activity or elevation between months. Takins on elevated structures were less often recorded active when compared to their behavior at ground level, and males were observed more often standing still rather than laying down when elevated compared to the female. The arthritic male was less active and less often observed on elevated structures in his habitat compared to the female and older male, though his activity and climbing seemed to improve after medical interventions that included two rounds of stem cell treatments.

It is generally considered more ethical to house birds in aviaries than to practice flight restraint through wing clipping or pinioning, which means that aviaries are needed to prevent birds from escaping. Traditionally, rectangular aviaries are commonly used; these aviaries may not be well designed for bird flight, especially for large-bodied species. In this paper, we draw attention to the circular flight aviary, a design which has the potential to encourage extended flight in captive birds without the need for excessively large exhibit design. Several circular flight aviaries are already used in select zoos globally, but there is at present, limited empirical evidence on the welfare benefits for birds. We evaluate the tools that are required to assess the effects of circular flight aviary design on bird welfare, with a focus on aspects of exercise physiology that are sometimes overlooked in traditional welfare assessments. The circular design may also be used to overcome challenges associated with breeding birds in complex social structures, such as those which benefit from being housed in large flocks yet are intolerant of other individuals when nesting. Circular flight aviaries, if developed with a view to generating an evidence base, have the potential to improve bird welfare, at a time when bird flight is becoming more restricted globally due to disease implications.","PeriodicalId":24035,"journal":{"name":"Zoo Biology","volume":" ","pages":"293-303"},"PeriodicalIF":1.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144035533","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}
