It has been proposed that inbreeding contributes to the decline and eventual extinction of small and isolated populations,. There is ample evidence of fitness reduction due to inbreeding (inbreeding depression) in captivity and from a few experimental, and observational field studies,, but no field studies on natural populations have been conducted to test the proposed effect on extinction. It has been argued that in natural populations the impact of inbreeding depression on population survival… 

STRONG INBREEDING DEPRESSION IN A DAPHNIA METAPOPULATION

TLDR
The presence of strong inbreeding depression in a rockpool metapopulation of the planktonic freshwater crustacean Daphnia magna, which reproduces by cyclical parthenogenesis, suggests that if rockpool populations are inbred, hybrid offspring resulting from crosses between immigrants and local genotypes might have a strong selective advantage.

ENVIRONMENTAL CONDITIONS AFFECT THE MAGNITUDE OF INBREEDING DEPRESSION IN SURVIVAL OF DARWIN'S FINCHES

TLDR
Quantifying inbreeding depression in survival and reproduction in populations of cactus finches and medium ground finches living on Isla Daphne Major in the Galápagos Archipelago suggests that substantial inbreeding Depression can exist in insular populations of birds, and that the magnitude of the inbreeding depressed is a function of environmental conditions.

Scaling up the effects of inbreeding depression from individuals to metapopulations.

TLDR
It is shown that genetic factors, in addition to demographic factors, can contribute to extinctions of small local populations and also of metapopulations and the results show that inbreeding is more frequent in small habitat networks, and consequently, inbreeding depression elevates extinction risks in small metAPopulations.

Inbreeding Depression and Genetic Rescue in a Plant Metapopulation

  • C. Richards
  • Biology, Environmental Science

  • 2000
TLDR
It is suggested that population connectivity through pollen‐mediated gene flow may have substantial effects on the persistence of isolated colonies and on the spatial structure of a metapopulation in general.

Inbreeding and population dynamics: implications for conservation strategies

TLDR
The study by Reed, Nicholas & Stratton (2007) focuses on whether inbreeding levels, within several populations of wolf spiders that differ in life history, negatively impact population dynamics and increase the risk of extinction.

Inbreeding and extinction: Effects of rate of inbreeding

TLDR
It is concluded that purging may slow the rate of extinction slightly, but it cannot berelied on to eliminate the deleterious effect of inbreeding.

Does inbreeding affect the extinction risk of small populations?: predictions from Drosophila

TLDR
It is shown that inbred populations have a significantly higher short‐term probability of extinction than non‐inbred populations, even for low levels of inbreeding, and that the extinction probability increases with increasing inbreeding levels.

Population type can influence the magnitude of inbreeding depression in Clarkia concinna (Onagraceae)

TLDR
The view that even when inbreeding depression is predicted to be less problematic, it may still be an important force influencing the fitness of populations is supported.

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.

Inbreeding and Extinction: A Threshold Effect

TLDR
Methods were devised to separate genetic and nongenetic causes of extinction in inbred populations, and they were used to analyze data from Drosophila melanogaster, D. virilis and Mus musculus, which showed notably increased extinction beginning at intermediate levels of inbreeding.

The Natural History of Inbreeding and Outbreeding: Theoretical and Empirical Perspectives

TLDR
Whether inbreeding is as problematic as biologists have thought, under what ecological conditions inbreeding occurs, and whether organisms that inbreed have mechanisms to dampen the anticipated problems of reduced genetic variation are asked.

INBREEDING DEPRESSION AND ITS EVOLUTIONARY CONSEQUENCES

TLDR
The evidence that the evolution of breeding systems of animals and plants has been significantly influenced by the occurrence of inbreeding depression is reviewed, and the contemporary genetic theory of inmarriage depression and heterosis and the experimental data concerning the strength of in breeding depression are considered.

Purging inbreeding depression and the probability of extinction: full-sib mating

TLDR
The effectiveness of purging the genetic load is examined by documenting both the reduction in inbreeding depression and the increase of the probability of extinction when there is continous full-sib mating.

An experimental study of inbreeding depression in a natural habitat.

TLDR
This study demonstrates that inbreeding had a significant detrimental effect on the survivorship of mice reintroduced into a natural habitat, and was more severe than the effect observed in laboratory studies of the population.

Metapopulation structure and migration in the butterfly Melitaea cinxia

TLDR
The modelling results demonstrate that it is possible to have empty habitat patches in a metapopulation in spite of frequent migration, as the butterfly M. cinxia was observed, and support the assumptions of structured metAPopulation models.

INCREASED PROBABILITY OF EXTINCTION DUE TO DECREASED GENETIC EFFECTIVE POPULATION SIZE: EXPERIMENTAL POPULATIONS OF CLARKIA PULCHELLA

  • D. NewmanD. Pilson
  • Environmental Science, Biology
    Evolution; international journal of organic evolution
  • 1997
TLDR
Decreased genetic effective population size, which leads to both inbreeding and the loss of alleles by genetic drift, increased the probability of population extinction over that expected from demographic and environmental stochasticity alone.

Estimates of Lethal Equivalents and the Cost of Inbreeding in Mammals

TLDR
The cost of inbreeding in natural populations of mammals are unknown despite their theoretical importance in genetic and sociobiological models and practical applications in conservation biology, and the regression of juvenile survival on the inbreeding coefficient using pedigrees of 40 captive mammalian populations belonging to 38 species is estimated.

Multiple equilibria in metapopulation dynamics

TLDR
It is shown that the probability of local extinction decreases with increasing population size and increasing immigration rate, and that local populations tend to be larger in regions with higher density of extant populations, results consistent with model assumptions and predictions.
