Survival, dispersal, and home-range establishment of reintroduced captive-bred puaiohi, Myadestes palmeri

Dispersal, home range establishment, survival, and reproduction of translocated eastern box turtles, Terrapene c. carolina

The feasibility of translocationto establish a population of the eastern box turtle (Terrapene c. carolina) was studied at Floyd Bennett Field, Brooklyn,NewYork, USA. The 579 ha site, originally salt marsh, was Ž lled during the 1920’s to construct a now-abandoned airport. It consists primarily of grasslands, native shrub thickets and woodlands, and mixed stands dominated by giant reed (Phragmi...

Reintroduction of captive-bred animals

The Hustain Nuru region of Mongolia’s Chentai Mountains is one of the country’s most pristine wild areas. Valleys and slopes harbour steppe vegetation such as fescue, brome grass and feathergrasses, while birch woods grow in the upper elevations of this relatively low lying mountainous region. A diverse range of wild fauna including marmots, lemmings, red deer, wild sheep, polecats, Pallas cat,...

Potential disruption of seed dispersal in the absence of a native Kauai thrush

Hawaii has experienced a catastrophic decline in frugivorous native birds coupled with the introduction of non-native species. Puaiohi (Myadestes palmeri), a critically endangered thrush, is the sole extant native songbird capable of dispersing fleshy fruited plants in the rainforest of Kauai island, Hawaii. As this species has declined to occupy a small proportion of its original range, a suit...

Reintroduction Schemes for Captive-bred Animals

Average dispersal success: linking home range, dispersal, and metapopulation dynamics to reserve design.

Spatially explicit models for populations are often difficult to tackle mathematically and, in addition, require detailed data on individual movement behavior that are not easily obtained. An approximation known as the "average dispersal success" provides a tool for converting complex models, which may include stage structure and a mechanistic description of dispersal, into a simple matrix mode...
