Directions in conservation biology
TLDR
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.Abstract:
Conservation biology has two threads: the small-population paradigm which deals with the erect of smallness on the persistence of a population, and the declining-population paradigm which deals with the cause of smallness and its cure. The processes relevant to the small-population paradigm are amenable to theoretical examination because they generalize across species and are subsumed by an inclusive higher category: stochasticity. In contrast, the processes relevant to the declining-population paradigm are essentially humdrum, being not one but many. So far they have defied tight generalization and hence are of scant theoretical interest. 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 causeread more

Inbreeding effects in wild populations.

TL;DR: This work reveals that levels of inbreeding depression vary across taxa, populations and environments, but are usually substantial enough to affect both individual and population performance.

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.

Synergies among extinction drivers under global change.
Barry W. Brook,Navjot S. Sodhi,Corey J. A. Bradshaw,Corey J. A. Bradshaw,Corey J. A. Bradshaw +4 more
TL;DR: Estimates of extinction risk for most species are more severe than previously recognised and conservation actions which only target single-threat drivers risk being inadequate because of the cascading effects caused by unmanaged synergies.

Inbreeding and extinction in a butterfly metapopulation
TL;DR: The effect of inbreeding on local extinction in a large metapopulation of the Glanville fritillary butterfly is studied and it is found that extinction risk increased significantly with decreasing heterozygosity, an indication of inmarriage.
