Impacts of landscape change on wolf restoration success: Planning a reintroduction program based on static and dynamic spatial models

Article Abstract:

Static and dynamic spatial models was used to evaluate whether a proposed wolf reintroduction to the southern Rocky Mountain region (SRM), U.S.A would advance recovery by increasing species distribution beyond what might be expected through natural range expansion. A consistent message emerges from the two models regarding what portions of the SRM have the highest potential to support wolves and how that potential compares with previous reintroduction areas.

Successful reintroduction of captive-raised yellow-shouldered Amazon parrots on Margarita Island, Venezuela

Article Abstract:

Yellow-shouldered Amazon parrots (Amazona barbadensis) of Venezuela have been raised in captivity and successfully reintegrated into a resident population in their natural environment. Twelve parrots were released, four with radio transmitters. All the birds with radio transmitters survived and adapted to the natural environment. Ten of the 12 released birds lived at least a year after the release, and at least one was known to have lived 34 months.

Status and restoration options for Atlantic sturgeon in North America

Article Abstract:

Several strategies can be used to restore Atlantic sturgeon stocks in the North American coastal regions. These include harvest stoppages to permit natural recolonization and reintroduction or supplementation processes such as hatchery-based stocking. Harvest stoppages avoid the genetic risks of hatchery-based stocking, but natural recovery may take long periods of time before appropriate population levels are reached.
