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.

Population Viability Analysis to Inform Reintroduction Decisions for a Group‐Living Primate, the Barbary Macaque

Animal Conservation, EarlyView.
We developed a population viability analysis to inform reintroduction strategies for the endangered Barbary macaque (Macaca sylvanus), incorporating age‐specific vital rates, release costs on survival and reproduction, environmental and demographic stochasticity, and catastrophic events.

Release from natural enemies mitigates inbreeding depression in native and invasive Silene latifolia populations

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 ...

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.

THE COST OF FLUCTUATING INBREEDING DEPRESSION [PDF]

Evolution, 2002
We present a phenotypic model for the evolution of self-fertilization in an infinite population of annual hermaphrodites for the case in which fitness and inbreeding depression vary among generations (e.g., due to fluctuations in the environment from year to year).

Parental Age, Inbreeding and Incubation Method Influence Extremely Low Hatching Success in the Ex‐Situ Population of the Extinct in the Wild Sihek

Animal Conservation, EarlyView.
Reproductive success rates are a key parameter determining the recovery potential of ex‐situ managed threatened species, with high rates often being required to produce offspring for wild releases while ensuring ex situ population viability. Here, we quantify reproductive success rates in the Extinct in the Wild sihek (Guam kingfisher) and find ...

Using Periodic Matrix Models to Simulate the Effectiveness of Alternative Reintroduction Strategies for Lizards on a Seasonal Tropical Island

Animal Conservation, EarlyView.
Guam's lizard fauna has been devastated by the invasive brown treesnake, but recent advances in brown treesnake control have opened the possibility of reintroducing native lizards. We simulated different strategies for reintroducing lizards to Guam, comparing the timing and age‐structure of releases.

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

Animal Conservation, EarlyView.
The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...
