Zoo Biology, EarlyView.ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

BMC Evolutionary Biology, 2008 Background Solanum carolinense (horsenettle) is a highly successful weed with a gametophytic self-incompatibility (SI) system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The

Effect of recent and ancient inbreeding on production and fertility traits in Canadian Holsteins
BMC Genomics, 2020 Background Phenotypic performances of livestock animals decline with increasing levels of inbreeding, however, the noticeable decline known as inbreeding depression, may not be due only to the total level of inbreeding, but rather could be distinctly ...

Inbreeding depression in a parasitoid wasp with single-locus complementary sex determination. [PDF]
PLoS ONE, 2014 Inbreeding and inbreeding depression are key processes in small or isolated populations and are therefore central concerns for the management of threatened or (re)introduced organisms.

Inbreeding depression in Zebu cattle traits [PDF]
Journal of Animal Breeding and Genetics, 2016 SummaryThe productivity of herds may be negatively affected by inbreeding depression, and it is important to know how intense is this effect on the livestock performance. We performed a comprehensive analysis involving five Zebu breeds reared in Brazil to estimate inbreeding depression in productive and reproductive traits.

Early acting inbreeding depression can evolve as an inbreeding avoidance mechanism
Proceedings of the Royal Society B: Biological Sciences, 2023 Despite the potential for mechanical, developmental and/or chemical mechanisms to prevent self-fertilization, incidental self-fertilization is inevitable in many predominantly outcrossing species. In such cases, inbreeding can compromise individual fitness. Unquestionably, much of this inbreeding depression is maladaptive.

Integrative Zoology, EarlyView.Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Ecology and Evolution, 2019 Inbreeding and enemy infestation are common in plants and can synergistically reduce their performance. This inbreeding ×environment (I × E) interaction may be of particular importance for the success of plant invasions if introduced populations ...

The role of inbreeding and outbreeding in herbivore resistance and tolerance in Vincetoxicum hirundinaria [PDF]
, 2017 Background and Aims Inbreeding via self-fertilization may have negative effects on plant fitness (i.e. inbreeding depression). Outbreeding, or cross-fertilization between genetically dissimilar parental plants, may also disrupt local adaptation or ...

Heterozygosity-fitness correlations and inbreeding depression in two critically endangered mammals [PDF]
, 2013 The relation among inbreeding, heterozygosity, and fitness has been studied primarily among outbred populations, and little is known about these phenomena in endangered populations.
