Host‐mediated filtering and interspecific associations structure strongyle parasite communities in Sable Island horses

open access: yesJournal of Animal Ecology, EarlyView.
Using individual‐level nemabiome metabarcoding of 3147 samples from 916 horses on Sable Island over 10 years, we generate the largest dataset of its kind to date. This unprecedented scale enables a rare test of the processes structuring parasite communities in a natural system, revealing dominant host‐mediated filtering and predominantly positive ...

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

open access: yesIntegrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

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

open access: yesIntegrative 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 ...

Trends in genetic diversity and the effect of inbreeding in American Angus cattle under genomic selection

open access: yesGenetics Selection Evolution, 2021
Background While the adoption of genomic evaluations in livestock has increased genetic gain rates, its effects on genetic diversity and accumulation of inbreeding have raised concerns in cattle populations.

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

open access: yesIntegrative 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.

Genomic Diversity of the Endangered Guinan Toad‐Headed Lizard and Its Conservation Implications

open access: yesIntegrative Zoology, EarlyView.
We produced HiFi long reads and assembled a high‐quality genome for the Guinan toad‐headed lizard—Phrynocephalus guinanensis—and present a comprehensive conservation genomics assessment. Our findings clearly show population structure, a reduced genetic diversity pattern, and a strong bottleneck in demographic history, reaffirming the endangered status ...

Analysis of Czech cold-blooded horses: genetic parameters, breeding value and the influence of inbreeding depression on linear description of conformation and type characters

open access: yesCzech Journal of Animal Science, 2011
Genetic parameters, breeding values and inbreeding depression for 22 linear type description of conformation and type characters and 4 body measurements were evaluated in a group of 1744 horses of three original cold-blooded breeds in the Czech Republic ...

Evidence of Inbreeding Depression on Human Height

open access: yesPLoS Genetics, 2012
Stature is a classical and highly heritable complex trait, with 80%-90% of variation explained by genetic factors. In recent years, genome-wide association studies (GWAS) have successfully identified many common additive variants influencing human height; however, little attention has been given to the potential role of recessive genetic effects. Here,

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

open access: yesAnimal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

Genomic dissection of inbreeding depression: a gate to new opportunities

open access: yesRevista Brasileira de Zootecnia
Inbreeding depression, reduction in performance of quantitative traits, including reproduction and survival, caused by inbreeding, is a well-known phenomenon observed in almost all experimental, domesticated, and natural populations.
