Genetic Management of Fragmented Populations
Involves applying evolutionary genetic theory to address inbreeding and loss of genetic diversity in small isolated populations.
Fragmented Distributions
Result from human activities, leading to small isolated populations with increased inbreeding, reduced genetic diversity, and elevated extinction risks.
Inbreeding Depression
Occurs in naturally outbreeding species due to inbreeding, reducing survival and reproduction, increasing extinction risk.
Augmenting Gene Flow
Reverses inbreeding depression, loss of genetic diversity, and evolutionary potential by introducing genetic diversity from different populations.
Outbreeding Depression
Occurs occasionally from crossing between populations but is predictable and less severe than inbreeding depression.
Temporary Outbreeding Depression
Often temporary as natural selection removes harmful effects in most cases.
Unsuitable Species Definitions
Phylogenetic and General Lineage Species Concepts are unsuitable for conservation; recommend using reproductive isolation for delineations.
Standardized Delineation Protocols
Urged for conservation purposes to include appropriate species concepts, sampling regimes, and statistical analyses.
Population Differentiation
Important to distinguish between drift and differential adaptation when managing gene flow among populations.
Genetic Rescue
Recommend augmenting gene flow for outbreeding species suffering inbreeding and low genetic diversity if benefits outweigh costs and risks.
Fitness Benefits
Fitness benefits from crossing may not persist in selfing and mixed mating species as in outcrossing species.
Genetic Management Actions
Assess risks and benefits of different scenarios; inaction can harm population persistence.
Managing Gene Flow
Minimize mean kinship among isolated populations to maximize genetic diversity if kinship analyses are not feasible.
Adaptability
Species need to be more adaptable to cope with global environmental change, increasing the need for genetic management.
Integrated Management
Threatened species require integrated management across populations, disciplines, and political boundaries for effective conservation.
