Restoring species through reintroductions: strategies for source population selection

Only a quarter of reintroduction programs succeed in restoring a self‐sustaining population of an extirpated species. Optimal source population selection for restoration efforts can increase the fitness of translocated individuals and improve reintroduction success. Here, we describe the support for two strategies for selecting source populations: pre‐existing adaptation and adaptive potential. The pre‐existing adaptation strategy focuses on source populations with a high frequency of genotypes… 

Conservation through the lens of (mal)adaptation: Concepts and meta‐analysis

A meta‐analysis of a small number of available studies is used to evaluate whether the different conservation strategies employed are better suited toward increasing population fitness across multiple generations, and finds weakly increasing adaptation over time for transgenerational plasticity, genetic rescue, and evolutionary rescue.

Are we adequately assessing the demographic impacts of harvesting for wild‐sourced conservation translocations?

Translocation, the human‐mediated movement of organisms from one area to another, is a popular tool in conservation management. Wild‐caught individuals are more likely to persist following release

Integrating genomics in population models to forecast translocation success

A framework to improve translocation success is proposed by integrating lab‐based and field‐collected data with model‐driven research, which could address long‐standing challenges in restoration ecology, such as when selecting locally adapted genotypes will aid translocation of plants and animals.

Population genetic structure of Texas horned lizards: implications for reintroduction and captive breeding

The Texas horned lizard (Phrynosoma cornutum) inhabits much of the southern Great Plains of North America. Since the 1950s, this species has been extirpated from much of its eastern range and has

Maternal Effects and the Evolution of Chinook Salmon

This work reared Chinook salmon embryos in-situ and found that egg size had a linear, non-linear, or no effect on early life survival depending on the habitat characteristics of the nest, which demonstrates the significant contribution maternal effects make to the expression and evolution of offspring phenotypes in salmon.

It’s not there, but it could be: a renewed case for reintroduction of a keystone species into the Lower River Murray

ABSTRACT The extinction of species not only contributes to the loss of biodiversity but also the disruption of ecological interactions, processes and functioning. This is particularly true with the

Phylogeography of Oribi Antelope in South Africa: Evolutionary Versus Anthropogenic Panmixia

The data indicate that the South African subspecies is distinct from other subspecies to the north, confirming that oribi in South Africa should be managed as a distinct conservation unit.

Identifying source populations for the reintroduction of the Eurasian beaver, Castor fiber L. 1758, into Britain: evidence from ancient DNA

The utility of aDNA is highlighted in reconstructing population histories of extirpated species which has real-world implications for conservation planning and the mode of postglacial population expansion from refugia was investigated by employing tests of neutrality and a pairwise mismatch distribution analysis.

Impacts of acidification on brown trout Salmo trutta populations and the contribution of stocking to population recovery and genetic diversity

Overall genetic diversity and extant populations have been increased by allochthonous stocking, and the genetically unique Loch Grannoch S. trutta was successfully used as a donor stock to restore populations in two acidic lochs.



Directions in reintroduction biology.

Mixed‐source reintroductions lead to outbreeding depression in second‐generation descendents of a native North American fish

Differences in fitness surrogates among crosstypes were consistent with disrupted co‐adapted gene complexes associated with beneficial adaptations in these reintroduced populations, and future reintroductions may be improved by evaluating the potential for local adaptation in source populations.

Restoration demography and genetics of plants: when is a translocation successful?

The ways translocations have been evaluated at various stages during the process of restoration are considered, with genetic issues are paramount, as restorationists need to consider inbreeding depression, reproductive viability, local adaptation, and evolutionary potential of translocated populations.

Transplantation of the Subshrub Lotus scoparius: Testing the Home-Site Advantage Hypothesis

The data support the home-site advantage hypothesis and the idea that mis-matching source populations of these genetically differentiated seed sources may result in lowered success of restored or constructed populations.

Reintroduction of Castilleja levisecta: Effects of Ecological Similarity, Source Population Genetics, and Habitat Quality

Although measures of genetic diversity, population size, and geographic distance are often used to make conservation decisions during species recovery, here they were poor predictors of C. levisecta performance and establishment.

Restoration Biology: A Population Biology Perspective

Five research areas of particular importance to restoration biology that offer potentially unique opportunities to couple basic research with the practical needs of restorationists are discussed.

Guidelines for Subspecific Substitutions in Wildlife Restoration Projects

Reintroduction of animals is becoming increasingly popular as a means of restoring populations of threatened species. Sometimes depletion of wild populations leaves only captive populations from

Nonlocal transplantation and outbreeding depression in the subshrub Lotus scoparius (Fabaceae).

The genetic background of transplants used to create or augment wild populations may affect the long-term success of restored populations. If seed sources are from differently adapted populations,

How successful are plant species reintroductions


It is suggested that the conservation goal should be to conserve ecological and evolutionary processes; rather than to preserve specific phenotypic variants - the products of those processes - to conserve historically isolated sets of populations.
