Genome evolution of the psammophyte Pugionium for desert adaptation and further speciation

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance Plants’ adaptations to and divergence in arid deserts have long fascinated scientists and the general public. Here, we present a genomic analysis of two congeneric desert plant species that clarifies their evolutionary history and shows that

Multidimensional divergent selection, local adaptation, and speciation

Evolution; international journal of organic evolution, 2021
Divergent selection applied to one or more traits drives local adaptation and may lead to ecological speciation. Divergent selection on many traits might be termed “multidimensional” divergent selection.

Does speciation between Arabidopsis halleri and Arabidopsis lyrata coincide with major changes in a molecular target of adaptation? [PDF]

PLoS ONE, 2011
Ever since Darwin proposed natural selection as the driving force for the origin of species, the role of adaptive processes in speciation has remained controversial.

Genomic signatures of host-associated divergence and adaptation in a coral-eating snail, Coralliophila violacea (Kiener, 1836). [PDF]

, 2020
The fluid nature of the ocean, combined with planktonic dispersal of marine larvae, lowers physical barriers to gene flow. However, divergence can still occur despite gene flow if strong selection acts on populations occupying different ecological niches.

Limited dispersal and local adaptation promote allopatric speciation in a biodiversity hotspot

Molecular Ecology, 2021
Recently diverged or diverging populations can offer unobstructed insights into early barriers to gene flow during the initial stages of speciation. The current study utilised a novel insect system (order Mantophasmatodea) to shed light on the early ...

Climate Adaptation and Drift Shape the Genomes of Two Eel-Goby Sister Species Endemic to Contrasting Latitude

Animals, 2023
Deciphering the role of climate adaptation in generating genetic divergence and hence speciation is a central question in evolution. Comparisons of genomes of closely related species spanning selective climate gradients are particularly informative in ...

Genetic tests for ecological and allopatric speciation in anoles on an island archipelago. [PDF]

PLoS Genetics, 2010
From Darwin's study of the Galapagos and Wallace's study of Indonesia, islands have played an important role in evolutionary investigations, and radiations within archipelagos are readily interpreted as supporting the conventional view of allopatric ...

Megabase-scale presence-absence variation with Tripsacum origin was under selection during maize domestication and adaptation

Genome Biology, 2021
Background Structural variants (SVs) significantly drive genome diversity and environmental adaptation for diverse species. Unlike the prevalent small SVs (< kilobase-scale) in higher eukaryotes, large-size SVs rarely exist in the genome, but they ...

A Simulation Study of the Ecological Speciation Conditions in the Galician Marine Snail Littorina saxatilis

Frontiers in Genetics, 2022
In the last years, the interest in evolutionary divergence at small spatial scales has increased and so did the study of speciation caused by ecologically based divergent natural selection.

Who Replaces Whom? Local versus Non-local Replacement in Social and Evolutionary Dynamics [PDF]

, 2012
In this paper, we inspect well-known population genetics and social dynamics models. In these models, interacting individuals, while participating in a self-organizing process, give rise to the emergence of complex behaviors and patterns.
