Reintroduction programmes: genetic trade‐offs for populations
@article{Earnhardt1999ReintroductionPG, title={Reintroduction programmes: genetic trade‐offs for populations}, author={Joanne M. Earnhardt}, journal={Animal Conservation}, year={1999}, volume={2} }
Reintroductions of captive‐managed animals are a vital tool for the conservation of populations and species extinct in the wild. Because genetic diversity may impact population persistence, the genetic composition of reintroduced and captive populations is critical. For captive‐managed species with known pedigrees, individual animals can be selected to create reintroduced populations with specific genetic compositions. Five genetic and demographic strategies for selecting animals were tested on…

Founding Events and the Maintenance of Genetic Diversity in Reintroduced Populations
- Environmental Science
- 2009
Examination of factors that influence inbreeding dynamics and the long-term maintenance of genetic diversity in translocated populations of skinks and tuatara improves translocation planning for many species by offering guidelines for maximising genetic Diversity in founder groups and managing populations to improve theLong- term maintenance of diversity.
Genetic variation in a network of natural and reintroduced populations of Griffon vulture (Gyps fulvus) in Europe
- Environmental ScienceConservation Genetics
- 2007
This study analyzed genetic data from a network of native and reintroduced Griffon vulture populations successfully restored in Southern Europe to assess the level of fragmentation among native populations, the effectiveness of random choice of founders to retain genetic variability of the species, and the loss of genetic diversity in the reintroduced population.
Evaluation of the genetic management of the endangered black‐footed ferret (Mustela nigripes)
- Biology, Environmental Science
- 2003
The random mating strategy may be a viable alternative for managing large, stable, captive populations such as that of the black-footed ferret and detected small but measurable genetic differentiation between the reintroduced populations.
Role of genomics and transcriptomics in selection of reintroduction source populations
- Environmental ScienceConservation biology : the journal of the Society for Conservation Biology

Appropriate application of conservation genomics and transcriptomics has the potential to dramatically enhance reintroduction success in a time of rapidly declining biodiversity and accelerating environmental change.
Genetic Differentiation of Reintroduced Père David’s Deer (Elaphurus davidianus) Based on Population Genomics Analysis

The findings of this study could highlight the necessity of individual exchange between different facilities, and genetic management should generally be integrated into conservation planning with other management considerations.
Reintroduction of captive-born beach mice: the importance of demographic and genetic monitoring
- Environmental Science, BiologyJournal of Mammalogy
- 2017
The feasibility of using captive-born beach mice to reestablish populations when wild populations are too small to serve as donors for a translocation is demonstrated and genetics is monitored together with demographic patterns, because cryptic gene flow could affect how to interpret reintroduction success.
Rapid growth and genetic diversity retention in an isolated reintroduced black bear population in the central appalachians
- Environmental Science
- 2015
This bear population appears to be genetically isolated, but contrary to expectations, there is no evidence of genetic diversity loss or other deleterious genetic effects typically observed from small founder groups.
Genetic evaluation of the lake sturgeon reintroduction program in the Mississippi and Missouri Rivers
- Environmental Science
- 2007
This work evaluated the success of an ongoing lake sturgeon reintroduction program based upon its ability to adequately transmit the genetic diversity of the Lake Winnebago source population into reintroduced populations in the Mississippi and Missouri rivers.

Management Options for Preserving Genetic Diversity: Reintroduction of Guam Rails to the Wild
- Biology
- 1990
Results illustrate that some of the most common approaches to population management or population reintroduction may produce significant loss of genetic diversity, whereas certain genetic management options may actually increase genetic diversity over current population levels.
Importance of Genetic Variation to the Viability of Mammalian Populations
- Biology, Environmental Science
- 1997
Small populations lose genetic variability because of genetic drift, and inbreeding within populations can further decrease individual variability, and genetic threats to population viability will be expressed through their effects on and interactions with demographic and ecological processes.
Effect of new founders on retention of gene diversity in captive populations: A formalization of the nucleus population concept
- Biology, Environmental Science

In this article, mathematical models are developed to assess the effectiveness of the nucleus population concept in reducing the population sizes necessary to maintain appreciable amounts of gene diversity in captive populations.
Viable Populations for Conservation: Effective population size, genetic variation, and their use in population management
- Biology

It is shown how the effective size of a population, the pattern of natural selection, and rates of mutation interact to determine the amount and kinds of genetic variation maintained.
Puerto Rican Parrots and Potential Limitations of the Metapopulation Approach to Species Conservation
- Biology
- 1994
A case history is examined of the Puerto Rican Parrot as a case history in which this policy of subdivision of captive subgroups accompanied by exchanges of individuals can in themselves carry substantial risks that must be weighed against the presumed benefits of subdivision.
Selection against inbred song sparrows during a natural population bottleneck
- Biology, Environmental ScienceNature
- 1994
It is reported that song sparrows that survived a severe population bottleneck were a non-random subset of the pre-crash population with respect to inbreeding, and that natural selection favoured outbred individuals, suggesting that inbreeding depression was expressed in the face of an environmental challenge.
Persistence of Different‐sized Populations: An Empirical Assessment of Rapid Extinctions in Bighorn Sheep

Data suggest that population size is a marker of persistence trajectories and indicate that local extinction cannot be overcome because 50 individuals, even in the short term, are not a minimum viable population size for bighorn sheep.
