Interactive effects of inbreeding and endocrine disruption on reproduction in a model laboratory fish

Evolutionary Applications, 2013
Inbreeding depression is expected to be more severe in stressful environments. However, the extent to which inbreeding affects the vulnerability of populations to environmental stressors, such as chemical exposure, remains unresolved.

Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

A major QTL affects temperature sensitive adult lethality and inbreeding depression in life span in Drosophila melanogaster

BMC Evolutionary Biology, 2008
Background The study of inbreeding depression has major relevance for many disciplines, including conservation genetics and evolutionary biology. Still, the molecular genetic basis of this phenomenon remains poorly characterised, as knowledge on the ...

Characterizing Runs of Homozygosity and Inbreeding in American Mink Using SNP Data and Pedigree Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding increases the likelihood of deleterious recessive alleles becoming homozygous and consequently affecting economically important traits. Runs of homozygosity (ROH), the continuous homozygous segments of the genome and the higher than expected homozygosity (HOM) are genomic indicators of inbreeding, quantified as FROH and FHOM ...

Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

Journal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Individual variation in inbreeding depression: the roles of inbreeding history and mutation.

Genetics, 1995
Abstract We use mutation-selection recursion models to evaluate the relative contributions of mutation and inbreeding history to variation among individuals in inbreeding depression and the ability of experiments to detect associations between individual inbreeding depression and mating system genotypes within populations.

Identifying thermally tolerant bull kelp (Nereocystis luetkeana) source populations for restoration under climate change

Journal of Phycology, EarlyView.
Abstract Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains to facilitate the long‐term success of kelp restoration.

Inbreeding depression in Holstein cattle in Brazil

Revista Brasileira de Zootecnia
The objective of this study was to evaluate inbreeding depression in Holstein cows in Brazil, considering their 305-day milk production (MP), age of first calving (AFC), and calving interval (CI).

Genome‐wide association study of morphometric and metabolic characteristics in European populations of the sugar kelp Saccharina latissima

Journal of Phycology, EarlyView.
Abstract The sugar kelp Saccharina latissima is a promising candidate for sustainable aquaculture in the North Atlantic and Northeast Pacific, but genetic improvement has been hindered by a limited understanding of the genetic basis of economically important traits.

Apparent inbreeding preference despite inbreeding depression in the American crow

Molecular Ecology, 2019
AbstractAlthough matings between relatives can have negative effects on offspring fitness, apparent inbreeding preference has been reported in a growing number of systems, including those with documented inbreeding depression. Here, we examined evidence for inbreeding depression and inbreeding preference in two populations (Clinton, New York, and Davis,
