PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

New Phytologist, Volume 251, Issue 6, Page 3669-3686, September 2026.Genetic differentiation among the study species. Summary Hybridisation and whole‐genome duplication (WGD) are widespread in plants, yet their ecological consequences remain challenging to predict. In allopolyploids, where both processes coincide, ecological divergence is typically evaluated against a null hypothesis of ecological additivity.

BMC Evolutionary Biology, 2010 Background Elucidation of the mechanisms driving speciation requires detailed knowledge about the phylogenetic relationships and phylogeography of the incipient species within their entire ranges as well as their colonization history.

Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Clades, Grades, and the Genus Problem: A Case for Revising Hominin Taxonomy
American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.ABSTRACT Taxonomic practice in evolutionary biology increasingly prioritizes the recognition of monophyletic groups (clades), yet paleoanthropology still applies this principle inconsistently. Here, I outline these inconsistencies and broader challenges in hominin taxonomy and propose a potential solution.

Sympatric Speciation in Snails; a Largely Neglected Model [PDF]
Evolution, 1988 Usually, shells of snails are clearly either dextral or sinistral. That means that, if one looks at the apex, the whorls increase in width clockwise or counterclockwise, respectively. In a dextral shell, the soft parts of the animal have the proximal part of the genitalia situated asymmetrically at the right side of the head.

COEVOLUTION IN «A PREDATOR–PREY» SYSTEM: AN ECOGENETIC MODEL
Вавиловский журнал генетики и селекции, 2015 In most natural populations, intraspecies competition for natural resources is supplemented by a predator impact. We suppose that the mode and intensity of the interaction between a prey and its predator affects the course of competitive or sympatric ...

Ecology and Evolution, Volume 16, Issue 8, August 2026.There is debate over whether isolated populations of “pygmy” Australian freshwater crocodiles are a unique species. This is a conservation concern as these populations face unique challenges. We found some population differences which support these populations as being ecologically unique and valuable for targeted conservation.

Ecology and Evolution, Volume 16, Issue 8, August 2026.During the summer fallow period, Pomacea canaliculata enters estivation under high temperature and drought stress yet maintains a survival rate exceeding 92%. Restructuring of the gut microbiota and metabolic adaptations in the liver, particularly the stability of fatty acid profiles, underpin its strong estivation tolerance.
