AbstractThe main goal of ex situ conservation programs is to improve the chances of long term survival of natural populations by founding and managing captive colonies that can serve as a source of individuals for future reintroductions or to reinforce existing populations. The degree in which a captive breeding program has captured the genetic diversity existing in the source wild population has seldom been evaluated. In this study we evaluate the genetic diversity in wild and captive… 

Genetic assessment of captive red panda (Ailurus fulgens) population

Assessment of genetic diversity of the red panda population in Padmaja Naidu Himalayan Zoological Park, Darjeeling, which plays a pivotal role in ex situ conservation of red p Panda in India finds that regular supplementation with a pair of adult individuals every five years will increase survival probability and genetic diversity to 99 and 61 % respectively.

The Genetic Integrity of the Ex Situ Population of the European Wildcat (Felis silvestris silvestris) Is Seriously Threatened by Introgression from Domestic Cats (Felis silvestris catus)

The results suggest that the high genetic diversity of the captive population of Felis s.

The need for captive monitoring to involve, a priori, greater application of hypothesis testing through the use of well‐designed experiments and improved documentation of procedures adopted by specific programs for reducing the loss of genetic diversity and fitness is highlighted.

Testing the regional genetic representativeness of captive koala populations in South-East Queensland

Test captive koalas maintain sufficient microsatellite diversity to act as an in situ reservoir for neutral genetic diversity of regional populations, and Mitochondrial DNA suggests that captive founders were from a wider geographic source or that haplotypes have been lost locally.

Using microsatellite diversity in wild Anegada iguanas (Cyclura pinguis) to establish relatedness in a captive breeding group of this critically endangered species

The results of an analysis of captive founder relationships for six Cyclura pinguis acquired as adults in 1999 by the San Diego Zoo Institute for Conservation Research conclude that the C. Pinguis population on Anegada is not excessively inbred; however, further investigation is warranted.

High genetic diversity and demographic history of captive Siamese and Saltwater crocodiles suggest the first step toward the establishment of a breeding and reintroduction program in Thailand

The genetic diversity and population structure of 69 individual crocodiles, mostly members of captive populations, were analyzed using both mitochondrial D-loop DNA and microsatellite markers and detected bi-directional hybridization between male and female individuals of the parent species.

Using molecular methods to improve the genetic management of captive breeding programs for threatened species

Captive breeding programs have saved the black-footed ferret, Przewalski’s horse, and the California condor from final extinction and new wild populations of the golden lion tamarin, Arabian oryx, and whooping crane have been successfully re-established from captive stocks.

Methods and prospects for using molecular data in captive breeding programs: an empirical example using parma wallabies (Macropus parma).

The results indicated that microsatellite appraisals of parentage were useful with respect to clarifying pedigrees but that molecular assessments of founder relatedness provided very marginal benefits with regard to the preservation of genetic diversity and the avoidance of inbreeding.

Molecular genetic analysis of the yellow-breasted capuchin monkey: recommendations for ex situ conservation.

A preliminary assessment of the genetic variability of C. xanthosternos in captivity in Brazil showed that two of the five captive groups assessed had a genetic variability comparable to wild animals, however, the other three groups apparently require urgent management to improve its genetic variability.



Genetic evaluation of the three captive mexican wolf lineages

From molecular genetics data, particularly from microsatellite loci, it appears that all of the lineages consist of Mexican wolves, and none of them appear to have ancestry from dogs or coyotes.

Genetic Variation of Naturally Colonizing Wolves in the Central Rocky Mountains

Recovery of gray wolf (Canis lupus) populations in North America depends on minimizing human-caused mortality and enhancing migration from stable source populations to suitable habitat unoccupied by

Mitochondrial DNA phylogeography and population history of the grey wolf Canis lupus

The results suggest that fluctuating population sizes during the late Pleistocene have left a genetic signature on levels of variation in both species, and a statistical parsimony analysis indicates local genetic structure that suggests recent restricted gene flow.

Evidence of genetic distinction and long‐term population decline in wolves (Canis lupus) in the Italian Apennines

Results of a Bayesian coalescent model indicate that wolves in Italy underwent a 100‐ to 1000‐fold population contraction over the past 2000–10 000 years, suggesting that wolves have apparently been genetically isolated for thousands of generations south of the Alps.

Captive breeding, reintroduction, and the conservation genetics of black and white ruffed lemurs, Varecia variegata variegata

Genetic data were used to assess the ongoing management strategy for reintroducing individuals into the Betampona population and for introducing new founders into the ex situ population, demonstrating the utility of combining genetic information with a consideration of conservation priorities in evaluating the implementation of management strategies.

Ex-situ conservation of Black poplar in Europe: genetic diversity in nine gene bank collections and their value for nature development

The diversity was largest in the material collected from the regions in Southern Europe, and the most unique alleles were identified in the Danube region (Austria), the Rhône region (France), Italy, the Rijn region (The Netherlands), and the Ebro region (Spain).

Inbreeding and relatedness in Scandinavian grey wolves Canis lupus.

It is shown here that individual heterozygosity at a set of 29 microsatellite loci correlates closely to the degree of inbreeding in a captive grey wolf population, pointing out an additional risk for the small Swedish wild population.

Hybridisation between wolves and dogs in Latvia as documented using mitochondrial and microsatellite DNA markers

The results of molecular genetic analyses of 31 wolf samples collected in Latvia from 1997 to 1999, including six pups originated from a litter found in northern Latvia in March 1999, and six wolves showing morphological traits that suggested hybrid origin are reported.

Molecular Genetics of Pre‐1940 Red Wolves

The results are inconsistent with an ancient origin of the red wolf and support the hybridization model, which may have occurred repeatedly over time prior to European settlement in the southcentral United States or may have been induced recently by anthropogenic changes.

No Inbreeding Depression Observed in Mexican and Red Wolf Captive Breeding Programs

There is no evidence that inbreeding depression will prove a major obstacle to the success of either recovery effort, and both captive breeding programs appear to have less lethal equivalents than the median estimate for mammals.
