Inbreeding depression in the wild [PDF]
Heredity, 1999 Despite its practical application in conservation biology and evolutionary theory, the cost of inbreeding in natural populations of plants and animals remains to a large degree unknown. In this review we have gathered estimates of inbreeding depression (delta) from the literature for wild species monitored in the field. We have also corrected estimates

On the expected relationship between inbreeding, fitness, and extinction
Genetics Selection Evolution, 2006 We assessed the expected relationship between the level and the cost of inbreeding, measured either in terms of fitness, inbreeding depression or probability of extinction. First, we show that the assumption of frequent, slightly deleterious mutations do

The environmental dependence of inbreeding depression in a wild bird population. [PDF]
PLoS ONE, 2007 Inbreeding depression occurs when the offspring produced as a result of matings between relatives show reduced fitness, and is generally understood as a consequence of the elevated expression of deleterious recessive alleles.

A comparison of inbreeding depression in tropical and widespread Drosophila species. [PDF]
PLoS ONE, 2013 The evolutionary history of widespread and specialized species is likely to cause a different genetic architecture of key ecological traits in the two species groups. This may affect how these two groups respond to inbreeding.

ON THE MEASUREMENT OF INBREEDING DEPRESSION [PDF]
Evolution, 1994 Theory has shown that the fitness consequences of inbreeding can play a major role in the evolution of sex and reproduction (Maynard Smith 1977; Lloyd 1979; Shields 1982; Kondrashov 1985; Lande and Schemske 1985; Holsinger 1988; Charlesworth et al. 1991; Uyenoyama and Waller 1991 a and references therein).

Sex-specific inbreeding depression: A meta-analysis. [PDF]
Ecol Lett, 2022 Abstract Inbreeding depression, the reduced fitness of the offspring of related individuals, can affect males and females differently. Although a comprehensive theoretical framework describing the causes of sex‐specific inbreeding depression is lacking, empirical evidence suggests that often one sex tends to be more vulnerable than ...

Inbreeding, inbreeding depression, and infidelity in a cooperatively breeding bird. [PDF]
Evolution; international journal of organic evolution, 2018 Inbreeding depression plays a major role in shaping mating systems: in particular, inbreeding avoidance is often proposed as a mechanism explaining extra-pair reproduction in socially monogamous species. This suggestion relies on assumptions that are rarely comprehensively tested: that inbreeding depression is present, that higher kinship between ...

Inbreeding depression of reproductive traits in Japanese Black cattle using genomic information [PDF]
Animal BioscienceObjective The objective of this study was to evaluate genomic inbreeding in Japanese Black cattle and its effects on reproductive traits. Methods The study analyzed reproductive records and single nucleotide polymorphism (SNP) data from Japanese Black ...

VIRAL EPIZOOTIC REVEALS INBREEDING DEPRESSION IN A HABITUALLY INBREEDING MAMMAL [PDF]
Evolution, 2007 Inbreeding is typically detrimental to fitness. However, some animal populations are reported to inbreed without incurring inbreeding depression, ostensibly due to past "purging" of deleterious alleles. Challenging this is the position that purging can, at best, only adapt a population to a particular environment; novel selective regimes will always ...
