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 ...

Classical, Ancestral, and New Inbreeding of X-Chromosome in Czech Local Dairy Goat Breed

, 2023
The importance of the autosomal inbreeding coefficient for livestock production traits is well documented. In contrast, little is known about inbreeding coefficients for X-chromosomes in livestock populations. On the other hand, several studies have shown that genes on the X-chromosome can contribute to variation in the breeding values of traits ...

Behavioral inbreeding avoidance in wild African elephants

, 2007
The costs of inbreeding depression, as well as the opportunity costs of inbreeding avoidance,determine whether and which mechanisms of inbreeding avoidance evolve. In African elephants,sex-biased dispersal does not lead to the complete separation of male

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.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Quality of the Exotic Parasitoid Cotesia flavipes (Hymenoptera: Braconidae) Does Not Show Deleterious Effects after Inbreeding for 10 Generations.

PLoS ONE, 2016
Although the parasitoid Cotesia flavipes (Cameron) has proven effective in controlling sugarcane borer Diatraea saccharalis (Fabricius) for many years, concern has arisen over the quality of individuals produced at large scales.

Baseline Cortisol and Behavioral Phenotype Are Linked to Context‐Dependent Spatial Cognition and Space Use in Giant Pandas

Integrative Zoology, EarlyView.
Baseline cortisol and repeatable behavioral phenotypes were associated with context‐dependent spatial cognition in giant pandas. Individuals differed in spatial search performance under stable and changing resource conditions. Exploratory GPS analyses revealed directionally consistent but non‐significant patterns of space use in novel environments ...

A note on inbreeding in dairy cattle breeding [PDF]

, 2005
Starting from the study at the beginning of the East German "Heterosisfeldversuch", where PANICKE et al. (1975) considered the possibilities of a targeted use of inbreeding and heterotic effects, we show and discuss results of inbreeding studies in the ...

Captive Breeding of the Chinese Alligator Reduces Inbreeding but Increases Genetic Load

Integrative Zoology, EarlyView.
Captive breeding of the Chinese alligator successfully reduced genomic inbreeding but increased the burden of deleterious mutations. Genomic analyses indicate that managing both genetic diversity and genetic load is essential for the long‐term conservation of this critically endangered species.

On the prediction of simultaneous inbreeding coefficients at multiple loci

, 2004
A new deterministic method for predicting simultaneous inbreeding coefficients at three and four loci is presented. The method involves calculating the conditional probability of IBD (identical by descent) at one locus given IBD at other loci, and ...
