Captive breeding and the conservation of the threatened houbara bustards

Endangered Species Research, 2021
Translocation of captive-bred individuals to reinforce wild populations may be an important conservation approach for some species, but can be detrimental when employed to boost exploited wild populations, particularly where repeated long-term ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Vitamin A deficiency and its treatment in captive Sunda pangolins

Veterinary Medicine and Science, 2021
The high incidence of disease in captive pangolins is a major obstacle in pangolin‐conservation breeding programs. Therefore, elucidating pangolins’ susceptibility to disease is the key to conservation progress.

Breeding of Moorhen in Captivity

Japanese Journal of Ornithology, 1976
One-year old moorhens (Gallinula chloropus) hatched in an incubator and kept in captivity laidtheir eggs and bred for two successive years. In their first breeding season, one pair was formed andthey had one brood and raised two young. The second year's breeding of the same pair started nearlytwo months earlier and they had 3 broods in the year.The ...

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Captive breeding reduces brain volume in waterfowl (Anseriformes)

, 2008
Brain-size reduction in domesticated forms of mammals in comparison to their wild ancestors is well documented in numerous species. Although it does not involve intentional artificial selection for traits such as meat production, captive breeding also ...

Genetic Assessment of a Captive Population of Eurasian Stone-Curlew (Burhinus oedicnemus), Source for the Reinforcement of Wild Populations

Biology
Although ex situ conservation programs are increasingly valuable support tools for in situ conservation measures, success depends on these captive individuals to be genetically representative of the recipient population.

Nutritional composition and heavy metal content in breast and thigh muscles of wild and intensively reared common pheasants (Phasianus colchicus)

Journal of Veterinary Research, 2020
Differing conditions in captive breeding and in the wild have impact on the mineral profile of the pheasant carcass and its heavy metal contents. This may be an indicator of environmental contamination. The study evaluated the nutritional composition and
