Habitat restoration is a key management strategy for species that experience loss, fragmentation or degradation of their habitat. The St. Francis’ satyr is a federally endangered butterfly found only on Ft. Bragg Army Installation in North Carolina that depends on frequent disturbance to maintain its preferred habitat, ephemeral wetlands. Over the course of 4 years, we restored and maintained c...

Three captive gibbons (Hylobates leucogenys, H. gabriellae, and H. lar) were videotaped in the course of longitudinal exposure to mirrors introduced into their familiar cage or island housing situation. The gibbons, which differed in age, sex, species, and rearing condition, exhibited great individual differences in their behavioral reactions to mirrors, spanning from a minimal reaction dominat...

This retrospective survey identifies potential risk factors for developmental limb abnormalities in whooping crane (Grus americana) chicks reared at the International Crane Foundation between 1990 and 2006. We summarized a series of biologicallyrelevant preand post-hatch variables from this population using in-house aviculture and veterinary records, and then compared them between chicks with a...

The size and structure of an animal's brain is typically assumed to result from either natural or artificial selection pressures over generations. However, because a fish's brain grows continuously throughout life, it may be particularly responsive to the environmental conditions the fish experiences during development. Salmon are an ideal model system for studying these effects because natural...

Food-sharing behaviour was observed in 9 captive families of cotton-top tamarins (range 4-14 individuals per group), during meals of fresh fruit. Food was transferred to infants by their parents and older sibs in response to begging, and was also offered to them without prior solicitation. Older, mature, reproductively suppressed individuals shared more than young immature monkeys. Infants in l...

Atlantic salmon is one of the most widely known migratory fish species whose populations have declined because of hydropower installations. Attempts have been made to preserve salmon stocks in regulated rivers by building fishways for adult fish migrating upstream, but downstream migration of salmon smolts has been almost totally ignored. Instead, captive breeding programmes and extensive stock...

People living in Mesoamerica and what is now the eastern southwestern United States used turkeys ( Meleagris gallopavo ) as sources of meat, eggs, bones, feathers. Turkey husbandry domestication are confirmed two these regions (Mesoamerica American Southwest), but human-turkey interactions Eastern North (eastern Canada) not fully explored. We apply stable isotope (δ 13 C, δ 15 N) ancient mitoch...

Species Survival Plans and European Endangered Species Programmes have been developed for several species of endangered felids in order to build up captive reserve populations and support their conservation in the wild. The Siberian tiger (Panthera tigris altaica), snow leopard (Uncia uncia), cheetah (Acinonyx jubatus) and clouded leopard (Neofelis nebulosa) are managed in such ex situ conserva...

The flathead grey mullet ( Mugil cephalus ) is at the focus of an intense domestication effort. However, despite significant advances, aquaculture mullets still based on capture wild fingerlings in estuaries and stocking them into ponds. Such reliance seed limits production since it highly seasonal, unpredictable, hinders genetic improvement programs may negatively affect local fisheries. As ca...
