AbstractPopulations may respond to environmental changes through phenotypic plasticity, adaptation, migration, or suffer demographic declines if they are unable to respond. Climate change is already causing shifts in species ranges, changes in phenotypes, and altered life history traits and interspecific interactions.

Inbreeding and Inbreeding Depression
2020Inbreeding (also referred to as “consanguinity”) occurs when mates are related to each other due to incest, assortative mating, small population size, or population sub-structuring. Inbreeding results in an excess of homozygotes and hence a deficiency of heterozygotes.

Inbreeding and inbreeding depression of early life traits in a cooperative mammal [PDF]
Molecular Ecology, 2012 AbstractMating between relatives often results in negative fitness consequences or inbreeding depression. However, the expression of inbreeding in populations of wild cooperative mammals and the effects of environmental, maternal and social factors on inbreeding depression in these systems are currently not well understood.

Inbreeding depression in Leccese sheep
Small Ruminant Research, 2010Three closed flocks of Leccese sheep reared in southern Italy were used to study the effects of inbreeding on productive and reproductive performances. All the animals were grouped into three classes according to the inbreeding coefficients obtained by their pedigree: the first class included non-inbred animals (F = 0%); and the second and third ...

ANCESTRAL INBREEDING REDUCES THE MAGNITUDE OF INBREEDING DEPRESSION IN DROSOPHILA MELANOGASTER [PDF]
Evolution; International Journal of Organic Evolution, 2006 The influence of natural selection on the magnitude of inbreeding depression is an important issue in conservation biology and the study of evolution. It is generally expected that the magnitude of inbreeding depression in small populations will depend upon the average homozygosity of individuals, as measured by the coefficient of inbreeding (F ...

Inbreeding is the mating of related individuals. It leads to a reduced number of heterozygotes and ultimately to complete homozygosity. Inbreeding depression is often observed with inbreeding and can be defined as the decrease in mean value of a trait due to inbreeding.

Effect of rate of inbreeding on inbreeding depression in Drosophila melanogaster
Theoretical and Applied Genetics, 1989This experiment was designed to study the relationship between rate of inbreeding and observed inbreeding depression of larval viability, adult fecundity and cold shock mortality in Drosophila melanogaster. Rates of inbreeding used were full-sib mating and closed lines of N=4 and N=20. Eight generations of mating in the N=20 lines, three generations in

Simultaneous inbreeding modifies inbreeding depression in a plant–herbivore interaction
Ecology Letters, 2013AbstractBecause inbreeding is common in natural populations of plants and their herbivores, herbivore‐induced selection on plants, and vice versa, may be significantly modified by inbreeding and inbreeding depression. In a feeding assay with inbred and outbred lines of both the perennial herb, Vincetoxicum hirundinaria, and its specialist herbivore ...

Inbreeding depression and the cost of inbreeding on seed germination
Seed Science Research, 2015AbstractWe review the literature on effects of inbreeding depression (ID) on seed germination for 743 case studies of 233 species in 64 families. For 216 case studies, we also review the relationship between mass and germination in inbred vs. outbred seeds.

Abstract Inbreeding often results in a decline in fitness and performance. Estimates for the number of lethal alleles are discussed. Inbreeding combined with selection can result in purging and we discuss this.
