Genetics and demography in biological conservation
TLDR
The practical need in biological conservation for understanding the interaction of demographic and genetic factors in extinction may provide a focus for fundamental advances at the interface of ecology and evolution.Abstract:
Predicting the extinction of single populations or species requires ecological and evolutionary information. Primary demographic factors affecting population dynamics include social structure, life history variation caused by environmental fluctuation, dispersal in spatially heterogeneous environments, and local extinction and colonization. In small populations, inbreeding can greatly reduce the average individual fitness, and loss of genetic variability from random genetic drift can diminish future adaptability to a changing environment. Theory and empirical examples suggest that demography is usually of more immediate importance than population genetics in determining the minimum viable sizes of wild populations. The practical need in biological conservation for understanding the interaction of demographic and genetic factors in extinction may provide a focus for fundamental advances at the interface of ecology and evolution.read more

POPULATION GENETIC CONSEQUENCES OF SMALL POPULATION SIZE: Implications for Plant Conservation
TL;DR: The effects of genetic drift, inbreeding, and gene flow on genetic diversity and fitness in rare plants and small populations and those circumstances that are likely to put these plant species and populations at genetic risk are identified.

Directions in conservation biology
TL;DR: The small-population paradigm has not yet contributed significantly to conserving endangered species in the wild because it treats an erect (smallness) as if it were a cause and hence is of scant theoretical interest.

Genetics and extinction
TL;DR: There is now sufficient evidence to regard the controversies regarding the contribution of genetic factors to extinction risk as resolved, and if genetic factors are ignored, extinction risk will be underestimated and inappropriate recovery strategies may be used.
