DOI: 10.1002/ajb2.1441
Abstract: PREMISE Newly formed polyploids face significant obstacles to persistence and population establishment because of fitness costs of intercytotype mating. Selfing provides the opportunity to escape mate limitation, enabling production of new individuals and increasing the… read more here.

DOI: 10.1007/s00335-019-09805-4
Abstract: Inbreeding depression has been demonstrated to impact vital rates, productivity, and performance in human populations, wild and endangered species, and in recent years, the domestic species. In all cases, standardized, high-quality phenotype data on all… read more here.

Inbreeding affects personality and fitness of a leaf beetle

DOI: 10.1016/j.anbehav.2018.02.002
Abstract: Habitat loss and fragmentation, which are mostly anthropogenically caused, can lead to decreasing population sizes for many species. Consequently, the risk of inbreeding increases and inbreeding depression can be induced, which is likely to lead… read more here.

DOI: 10.1016/j.aquaculture.2020.735023
Abstract: Abstract Inbreeding depression is common, especially in hermaphroditic animals, and causes a decline in biological fitness. To evaluate the effects of inbreeding on giant clams, two by two factorial cross experiments between individuals were conducted… read more here.

DOI: 10.1016/j.gene.2018.04.047
Abstract: Inbreeding depression is the reduction in fitness observed in inbred populations. In plants, it leads to disease, weaker resistance to adverse environmental conditions, inhibition of growth, and decrease of yield. To elucidate molecular mechanisms behind… read more here.

Elevation-related variation in the population characteristics of distylous Primula nivalis affects female fitness and inbreeding depression
Sign Up to like & getrecommendations! Published in 2019 at "Plant Diversity"
DOI: 10.1016/j.pld.2019.06.004
Abstract: The population characteristics of distylous species are highly sensitive to stochastic natural selection pressure. Therefore, populations growing under different environmental conditions may vary in floral morph ratios, potentially affecting female fitness and leading to inbreeding… read more here.

Sibling competition does not magnify inbreeding depression in North American Arabidopsis lyrata

DOI: 10.1038/s41437-019-0268-1
Abstract: About half of all angiosperms have some form of molecular self-incompatibility to promote outcrossing. If self-incompatibility breaks down, inbreeding depression (δ) is the main barrier to the evolution of self-fertilisation (selfing). If inbreeding depression is… read more here.

Stresses affect inbreeding depression in complex ways: disentangling stress-specific genetic effects from effects of initial size in plants

DOI: 10.1038/s41437-021-00454-5
Abstract: The magnitude of inbreeding depression (ID) varies unpredictably among environments. ID often increases in stressful environments suggesting that these expose more deleterious alleles to selection or increase their effects. More simply, ID could increase under… read more here.

DOI: 10.1038/s41598-020-79979-4
Abstract: Inbreeding can depress individuals’ fitness traits and reduce population viability. However, studies that directly translate inbreeding depression on fitness traits into consequences for population viability, and further, into consequences for management choices, are lacking. Here,… read more here.
