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).

The Size, Demography, and Distribution of Cambodia's Largest Elephant Population Revealed Using Traditional Genetic Tools and a Novel SNP Panel

Integrative Zoology, EarlyView.
Asian elephant population parameters were assessed using microsatellite, SNP, and sex determination DNA markers. This represents one of the first studies in mainland Asia to demonstrate that integrating microsatellite and SNP data enhances genotyping success from degraded fecal samples, increases the number of useable samples and markers, and ...

Inbreeding management and optimization of genetic gain with phenotypic and genomic selection in oil palm (Elaeis guineensis)[W776] [PDF]

, 2020
Oil palm breeding relies on reciprocal recurrent selection between two heterotic groups complementary for bunch number and average bunch weight. Given the long generation interval and the limited selection intensity imposed by the progeny tests currently

Evidence for inbreeding depression in a species with limited opportunity for maternal effects [PDF]

, 2015
It is often assumed that mating with close relatives reduces offspring fitness. In such cases, reduced offspring fitness may arise from inbreeding depression (i.e., genetic effects of elevated homozygosity) or from post-mating maternal investment.

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.

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.

Evaluation and development of animal breeding in Ireland [PDF]

, 2008
End of project reportThe primary objectives of this study were: 1) to annually evaluate the pertinence of the Irish dairy cattle breeding index, the Economic Breeding Index (EBI) and where necessary modify, 2) to evaluate the potential of do-it-yourself ...

Understanding the evolution of native pinewoods in Scotland will benefit their future management and conservation [PDF]

, 2010
Scots pine (Pinus sylvestris L.) is a foundation species in Scottish highland forests and a national icon. Due to heavy exploitation, the current native pinewood coverage represents a small fraction of the postglacial maximum.

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 ...

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

Animal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.
