Effects of small population size and reduced genetic variation on the viability of wild animal populations remain controversial. During a 35-year study of a remnant population of greater prairie chickens, population size decreased from 2000 individuals in 1962 to fewer than 50 by 1994. Concurrently, both fitness, as measured by fertility and hatching rates of eggs, and genetic diversity declined significantly. Conservation measures initiated in 1992 with translocations of birds from large… 
Genetic rescue of an insular population of large mammals
TLDR
This is the first demonstration, to the authors' knowledge, of increased male and female fitness attributable to outbreeding realized in a fully competitive natural setting and suggests that genetic principles deserve broader recognition as practical management tools with near-term consequences for large-mammal conservation.
Conservation biology: Restoration of an inbred adder population
TLDR
It is shown that the introduction of new genes into a severely inbred and isolated population of adders (Vipera berus) halted its precipitous decline towards extinction and expanded the population dramatically.
Genetic consequences of small population sizes
TLDR
The Mauritius kestrel was reduced to a single pair but has now recovered to 400–500 birds, while the Mauna Kea silversword in Hawaii declined to about two dozen plants.
Experimental test of genetic rescue in isolated populations of brook trout
TLDR
Results provide much‐needed experimental data to inform the potential effectiveness of genetic rescue‐motivated translocations and strong evidence of hybrid vigour was observed through significantly larger body sizes of hybrid offspring relative to resident offspring in all recipient populations.
Founding Events and the Maintenance of Genetic Diversity in Reintroduced Populations
TLDR
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.
Genomic Consequences of Population Decline in the Endangered Florida Scrub-Jay
TLDR
Owing to regional population declines, immigration into the study population declined from 1995-2013, resulting in increased levels of inbreeding and reduced fitness via inbreeding depression, even as the population remained demographically stable.
Genetic restoration of a threatened population of greater prairie-chickens
TLDR
The results caution that introgression of new alleles varies for genetic markers that differ in selection and inheritance, and, thus, the success of genetic restoration projects may depend on how the goals are defined.
The importance of control populations for the identification and management of genetic diversity
TLDR
An example of how the lack of adequate controls may lead to erroneous conclusions for understanding the role that population size may play in the preservation of genetic diversity and fitness of natural populations is presented.
Loss of genetic variation and effective population size of Kirikuchi charr: implications for the management of small, isolated salmonid populations
TLDR
A need for recovering natural connections and potential gene flow among local populations is strongly indicated, given the small Ne of the two populations, and it would be necessary to retain gene flow artificially within or across local populations.
Influence of translocation strategy and mating system on the genetic structure of a newly established population of island ptarmigan
TLDR
For conservation efforts based on reintroductions, a mating system with high rates of multiple paternity may facilitate retention of genetic diversity, thereby reducing the potential for inbreeding in small or isolated populations.

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.
The Ghost of Genetic Diversity Past: Historical DNA Analysis of the Greater Prairie Chicken
TLDR
Analysis of DNA from museum specimens of the greater prairie chicken Tympanuchus cupido from central Illinois revealed the loss of specific alleles (known to have been present earlier in this century) following a demographic contraction.
Selection against inbred song sparrows during a natural population bottleneck
TLDR
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.
Mutation and Conservation
TLDR
The findings suggest that current recovery goals for many threatened and endangered species are inadequate to ensure long-term population viability.
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.
Reproductive Stages Limiting Productivity of the Endangered Attwater’s Prairie Chicken
TLDR
It is suggested that researchers focus on determining what proportion of Attwater's Prairie Chicken broods survive and why Attwater’s Prairie Chicken nesting and brood-rearing success are so poor relative to those of the Greater Prairie Chicken.
INBREEDING IN AN ISLAND POPULATION OF THE GREAT TIT
TLDR
There is clearly a need for quantitive data on inbreeding in natural populations, and the data from the long-term population studies of the Great Tit carried out at the Institute for Ecological Research at Arnhem allow us to give quantitative estimates of the occurrence and the effects of inbreeding.

Effects of flushing nesting greater prairie-chickens in Illinois
TLDR
To determine return rates of Greater Prairie-Chicken hens to their nests after investigator-induced disturbance, compare fates of investigator- Disturbed with undisturbed nests, compare embryonic mortality between investigator-disturbed and undistsurbed successful nests, and to determine if effects of investigator disturbance varied with stage in nesting cycle, or the number of hen flushes, are determined.
