Introgression between highly divergent sea squirt genomes: an adaptive breakthrough?
Peer Community Journal, 2022 Human-mediated introductions are reshuffling species distribution on a global scale. Consequently, an increasing number of allopatric taxa are now brought into contact, promoting introgressive hybridization between incompletely isolated species and new ...

An HMM-based comparative genomic framework for detecting introgression in eukaryotes. [PDF]
PLoS Computational Biology, 2014 One outcome of interspecific hybridization and subsequent effects of evolutionary forces is introgression, which is the integration of genetic material from one species into the genome of an individual in another species.

Adaptive Introgression Promotes Fast Adaptation In Oaks Marginal Populations [PDF]
, 2019 AbstractRange shifts and species range limits are two fundamental, related processes in population and evolutionary genetics that have received much attention since a large impact of climate change in species’ distributions was predicted. In general, there is a broad consensus on the effects of abiotic interactions on range limits, but comprehensive ...

Phylogenetic systematics of Juncaceae
American Journal of Botany, EarlyView.Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within it. In 2022, a new classification was proposed, based on phylogenies built from one nuclear and three plastid regions ...

Detecting cryptic ghost lineage introgression in four‐taxon genomic datasets
Applications in Plant Sciences, EarlyView.Abstract Premise Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four‐taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression from genomic data, which have played an important role in ...

Introgression from extinct species facilitates adaptation to its vacated niche
Molecular Ecology, 2022 AbstractAnthropogenic disturbances of ecosystems are causing a loss of biodiversity at an unprecedented rate. Species extinctions often leave ecological niches underutilized, and their colonization by other species may require new adaptation. In Lake Constance, on the borders of Germany, Austria and Switzerland, an endemic profundal whitefish species ...

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak
Animal Research and One Health, EarlyView.Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Biological Diversity, EarlyView.Integrating data from plastid genomes, nrDNA, and 353 low‐copy nuclear genes, this study establishes a robust phylogenetic framework for Hylodesmum. This framework supports a taxonomic revision recognizing 18 species and reveals a complex pattern of bidirectional EA–ENA dispersal, with mammals as a plausible dispersal agent. ABSTRACT Phylogenomics with

Signatures of Archaic Adaptive Introgression in Present-Day Human Populations. [PDF]
Mol Biol Evol, 2017 AbstractComparisons of DNA from archaic and modern humans show that these groups interbred, and in some cases received an evolutionary advantage from doing so. This process - adaptive introgression - may lead to a faster rate of adaptation than is predicted from models with mutation and selection alone.

The spread of non‐native species
Biological Reviews, EarlyView.ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.
