Microsatellite-Based Genetic Structure and Diversity of Local Arabian Sheep Breeds
Frontiers in Genetics, 2018 The genetic diversity of the sheep breeds in the Arab countries might be considered to be a mirror of the ecology of the region. In this study, the genetic structure and diversity of sheep breeds from Saudi Arabia (Harri, Najdi, Naemi, Arb, and Rufidi ...

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
, 2020 Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Pleistocene glacial cycles drive isolation, gene flow and speciation in the high-elevation Andes.
New Phytologist, 2018 Mountain ranges are amongst the most species-rich habitats, with many large and rapid evolutionary radiations. The tempo and mode of diversification in these systems are key unanswered questions in evolutionary biology.

Evidence of gene flow between transgenic and non-transgenic maize in Colombia
Agronomía Colombiana, 2015 Maize (Zea mays) is an important crop worldwide and is essential for industry. Many transgenic cultivars of maize have been developed over the years from this species, producing cultivars resistant to herbicides and insects, among other things.

Whole-genome sequences of Malawi cichlids reveal multiple radiations interconnected by gene flow
Nature Ecology & Evolution, 2017 The hundreds of cichlid fish species in Lake Malawi constitute the most extensive recent vertebrate adaptive radiation. Here we characterize its genomic diversity by sequencing 134 individuals covering 73 species across all major lineages.
