Breeding Endangered Species

The Economics of Captive Breeding and Endangered Species Conservation

There is growing concern that the traditional "protectionist" approach to conservation is expensive and fails to deliver the desired environmental outcomes. Encouraged by economists, “supply side” policies to conserve endangered species have drawn support. By generating supplies from captive–bred animals, wildlife commodity prices are expected to fall, thereby lowering the incentive to poach sp...

Endangered species and endangered knowledge

The recent discovery of a new species of land iguana in the Galapagos (Tzika et al. 2008; Gentile et al. 2009; Gentile & Snell 2009) is indeed an exciting novelty, of great interest to all zoologists and evolutionary biologists. This species being apparently represented only by a very small population with a very limited range, it was described as a new taxon following an unusual procedure: no ...

Optimization Methods for Selecting Founder Populations for Captive Breeding of Endangered Species

Methods from genetics and genomics can be employed to help save endangered species. One potential use is to provide a rational strategy for selecting a population of founders for a captive breeding program. The hope is to capture most of the available genetic diversity that remains in the wild population, to provide a safe haven where representatives of the species can be bred, and eventually t...

Cloning endangered animal species?

Breeding system, flower visitors and seedling survival of two endangered species of Helianthemum (Cistaceae).

BACKGROUND AND AIMS Helianthemum marifolium and H. caput-felis are two endangered plant species of the western Mediterranean. Several aspects of the reproduction of both species were examined to determine whether their rarity could be related to factors causing reproductive limitation. METHODS The flowering and fruiting phenology of both species in two non-sympatric island populations (Mallor...
