Abstract Although critical to the conservation of white rhinoceros, captive breeding has proven challenging because poor and irregular reproductive health many rhinos, social interactions may play a significant role. This research investigated spatial relationships two groups southern rhinoceros ( Ceratotherium simum ) by examining frequency companion changes, number space maintenance vocalizations made per hour each reproductively mature female, dominant/subordinate interactions. The...
Abstract This study investigated sand tiger shark (STS; Carcharias taurus ) spatial use and exclusion in public aquarium enclosures using a novel protocol for three‐dimensional mapping. Fifty‐one STS were observed 14 enclosures, swimming pattern, depth, location recorded ZooMonitor. Data converted into quantitative, representations ArcGIS® Pro v. 2.9. All except one swam circular patterns, 80% ( n = 41) showed directional bias. Most (80%; predominantly utilized the top two‐thirds of though...
To better understand breeding conditions to promote reproduction in captive kori bustards, fundamental endocrine studies measuring fecal androgen metabolites male and female bustards were conducted. Feces collected weekly from males females analyzed for testosterone using enzyme‐linked immunoassay. Results adult ( n = 5), 10), immature 10) revealed seasonally elevated concentrations fertile, but not nonfertile P > 0.05). Adult that maintained a group, or did produce eggs, demonstrate...
Propagation of giant river otters (GRO) in zoos is inconsistent: some pairs never reproduce while others are prolific producing young but can be hindered by low cub survival. Developing effective breeding programs requires understanding normal reproductive parameters and behavior. Fecal samples were collected for 6-16 months from five pairs, two individual females, one female pair at seven zoos, analyzed fecal progesterone, estrogen, testosterone, glucocorticoid (FGM) metabolites via enzyme...
Abstract Reproductive management of the southern tamandua ( Tamandua tetradactyla ) should include timed introductions for breeding to minimize aggression and pregnancy monitoring. Since serial blood sampling could cause unnecessary stress, urinary progesterone metabolites are found in very low concentrations, this study sought validate estradiol enzyme immunoassays measuring fecal metabolite (FPM) estrogen (FEM) concentrations two females. Peaks FEM coincided with conception, were 5–6 times...
The threat of predation can cause increased adrenal secretion glucocorticoids that, if sustained, result in chronic stress that might predispose animals to disease, reduced growth, or poor fertility. Fecal glucocorticoid metabolite (FGM) concentrations were measured between September 2011 and July 2012 two Montana bison (Bison bison) herds, one herd living with the other without wolves (Canis lupus) their habitat. relevance FGM (as by corticosterone enzyme immunoassay) a confirmation an...
Nonbreeding white rhino bulls are traditionally housed individually in zoos, but space limitations require the exploration of alternative techniques. There no studies group-housed bulls, and feasibility managing a bachelor group is unknown. Six (two each 3-, 5-, 8-yr-olds) 3.1 ha enclosure were observed for 30 min 2×/wk 20–31 wks. The 3-yr-olds relocated after first 20 weeks. Rhino location, nearest neighbor, aggressive behaviors, dominance interactions recorded. was evidence habitat spatial...
This is the first time fecal prostaglandin F2α metabolite (PGFM) analysis and altrenogest were used to determine maintain a pregnancy in zoo-housed black-footed cat (BFC; Felis nigripes). The established pair had not produced offspring during year since their arrival at Birmingham Zoo. Fecal samples collected daily analyzed by enzyme immunoassay for progestagen, estrogen metabolite, PGFM concentrations. After 4-mo separation, was reintroduced, breeding reinitiated. Two pregnancies suggested...
