Ex situ population of Aldabrachelys gigantea (Reptilia: Testudines) in the European Association of Zoos and Aquaria and its perspectives: Hidden extinction and how to prevent it
For the needs of adequate management, we carried out an assessment of the Aldabrachelys gigantea (Schweigger, 1812) population in the institutions of the European Association of Zoos and Aquaria. This population was established a hundred years ago and is continuously growing. Today it is the largest ex situ population of all regional zoo associations. Currently […]
Captive breeding of cheetahs in North American Zoos: 1987–1991
Abstract 10.1002/zoo.1430120104.abs From 1987 to 1991, the North American captive cheetah population increased by 38% (to 266 animals), due to importation and captive breeding. This population constitutes 26% of the world’s captive cheetahs and 36% of all reproductively successful animals. Since 1956, 33% of all cubs born in North America occurred during this 5-year period. […]
Captive breeding of the cheetah (Acinonyx jubatus) in North American zoos (1871–1986)
Abstract 10.1002/zoo.1430080103.abs The African cheetah has been bred in North American zoological facilities since 1956. The captive population has since grown to around 200 animals because of a combined increase in importation plus captive births. From 1982 to 1986, the captive birth rate declined by 50%, primarily because of a low frequency of breeding individuals […]
Identifying parentage using molecular markers: Improving accuracy of studbook records for a captive flock of marabou storks (Leptoptilus crumeniferus)
Extra-pair copulations (EPCs) leading to extra-pair fertilization (EPF) are common in avian mating systems, despite the prevalence of observed social monogamy in many species. Colonially breeding birds are interesting species to investigate the prevalence of EPCs and EPF because they show nesting habits including close proximity of nest sites and sexual partners, which are proposed […]
