Endemic but not eroded: Genomic distinctiveness and conservation genomics of the British swallowtail butterfly (Papilio machaon britannicus)

Insect Conservation and Diversity, EarlyView.
Through whole‐genome sequencing of P. machaon populations across Europe, we demonstrate that P. m. britannicus forms a genetically distinct and isolated lineage. Demographic modelling revealed weak historical gene flow from the continent. Although P. m.

Partial selfing eliminates inbreeding depression while maintaining genetic diversity [PDF]

, 2017
Classical theory on the origin and evolution of selfing and outcrossing relies on the role of inbreeding depression created by unlinked partially-deleterious recessive alleles to predict that individuals from natural populations predominantly self or ...

Unravelling the Genetic Structure of Local and Mainstream Red‐Pied Cattle Breeds Using Genomics and Extended Pedigree Analysis

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT During the last decade, there has been a growing interest for local and endangered breeds as they are often seen as more resilient and healthier than mainstream breeds. They can also provide high added‐value products like meat or dairy products.

Whole genome sequencing informs SNP-based breeding strategies to safeguard genetic diversity in captive African lions

Frontiers in Veterinary Science
IntroductionAfrican lions (Panthera leo) face severe population declines, making captive breeding programs essential for conservation. However, genetic data scarcity in such programs elevates inbreeding risks and threatens genetic diversity.MethodsUsing ...

Partial Selfing Can Reduce Genetic Loads While Maintaining Diversity During Experimental Evolution

G3: Genes, Genomes, Genetics, 2019
Partial selfing, whereby self- and cross- fertilization occur in populations at intermediate frequencies, is generally thought to be evolutionarily unstable. Yet, it is found in natural populations.

From phenotypical to genomic characterisation of the mannara dog: an italian shepherd canine resource

Italian Journal of Animal Science, 2021
Mannara dogs have long been bred in Sicily (Italy) to work alongside shepherds as flock guardians. This study provides a morphologic, genealogic, and genomic characterisation of the Mannara dog, useful in light of its recognition process and to improve ...

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Inbreeding and Outbreeding Depression in Caenorhabditis Nematodes [PDF]

, 2007
The nematode Caenorhabditis elegans reproduces primarily by self-fertilization of hermaphrodites, yet males are present at low frequencies in natural populations (androdioecy). The ancestral state of C.

Effect of non-random mating on genomic and BLUP selection schemes

Genetics Selection Evolution, 2012
Background The risk of long-term unequal contribution of mating pairs to the gene pool is that deleterious recessive genes can be expressed. Such consequences could be alleviated by appropriately designing and optimizing breeding schemes i.e.
