Inbreeding depression in crambe1 [PDF]

Pesquisa Agropecuária Tropical, 2016
ABSTRACT Inbreeding depression in plants, caused by selfing or crossing among plants with a high degree of relatedness, is a genetic phenomenon that affects quantitative traits. This study aimed at verifying the occurrence of inbreeding depression in crambe progenies originated from selfing, in comparison with open pollination progenies.

Water depth and human disturbance drive occupancy of endangered softshell turtles (Nilssonia spp.) in eastern Nepal

Wildlife Biology, EarlyView.
Freshwater turtles play vital roles in maintaining the health of aquatic ecosystems by supporting ecological balance, nutrient cycling and regulating prey populations. Unfortunately, they are among the most threatened species worldwide. Habitat fragmentation, illegal trade, overharvesting for meat, and use in ethnomedicinal practices have severely ...

Analysis of Levels of Inbreeding and Inbreeding Depression in Jersey Cattle

Journal of Dairy Science, 1992
A pedigree file of 157,015 male and female Jersey cattle (born after 1955) from the Canadian herdbooks was investigated for the occurrence of inbreeding. A large proportion of Jersey bulls and cows were inbred (32.4 and 36.3% for bulls and cows, respectively). However, average inbreeding coefficients of these inbred cows and of all cows were low. First

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.

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

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 ...

Optimizing genetic diversity in Australian Holsteins and Jerseys: A comparative analysis of whole-genome and regional inbreeding depression effects

Journal of Dairy Science
: Homozygosity, which can arise from several genetic mechanisms including inbreeding, is frequently observed in the offspring of related parents. This inbreeding can lead to a reduced performance, owing to a phenomenon known as inbreeding depression ...

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 ...

Temporal and region‐specific variations in genome‐wide inbreeding effects on female size and reproduction traits of rainbow trout

Evolutionary Applications, 2022
Recent studies have shown that current levels of inbreeding, estimated by runs of homozygosity (ROH), are moderate to high in farmed rainbow trout lines.

Inbreeding evaluation using microsatellite confirmed inbreeding depression in growth in the Fenneropenaeus chinensis natural population

Frontiers in Genetics, 2023
Understanding inbreeding depressions (IBDs), the effect on the phenotypic performance of inbreeding, is of major importance for evolution and conservation genetics.
