Considerations about effective dissemination of improved fish strains [PDF]

, 2012
Aquaculture production systems in developing countries are largely based on the use of unimproved species and strains. As knowledge and experience are accumulated in relation to the management, feeding and animal health issues of such production systems,

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 ...

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

Integrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.

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).

Population genomic signatures of founding events in autonomously self-fertilizing plants: a test with Impatiens capensis. [PDF]

New Phytol
Summary Autonomously self‐fertilizing plants possess disproportionate abilities to found populations. Viewed from the metapopulation perspective, founding events should be frequent in such plants, but the intensity and timing of bottlenecks and recovery should vary among populations.

A Social Network Analysis of Occupational Segregation [PDF]

We develop a social network model of occupational segregation between different social groups, generated by the existence of positive inbreeding bias among individuals from the same group.

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

Animal Conservation, EarlyView.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.

Design and Application of a Genome-Wide SNP Array to Improve Conservation Outcomes in the Critically Endangered Southern Corroboree Frog. [PDF]

Mol Ecol Resour
ABSTRACT Species‐specific genomic information has the potential to transform modern conservation management strategies through improved genomic assessment and management outcomes. Gaining genomic insights into genetic diversity, adaptability and potential resilience against infectious diseases is essential to enhance conservation efforts for threatened

Prevalence and Pattern of Consanguineous Marriages Among Different Communities in Mangalore [PDF]

, 2013
Introduction: Consanguineous marriages are a common practice in the Middle East, Asian and African populations. Many studies have stated an association between first cousin marriages and the incidence of autosomal recessive diseases and congenital ...

Estimation of intrachromosomal inbreeding depression on female fertility using runs of homozygosity in Finnish Ayrshire cattle.

Journal of Dairy Science, 2018
Inbreeding increases homozygosity, which in turn increases the frequency of harmful recessive alleles, resulting in inbreeding depression. Inbreeding depression on fertility reduces the profitability of dairy farming by decreasing the lifetime milk ...
