Clinal Variation in Reproductive Modes and Offspring Body Condition Across a Contact Zone of a Bimodal Viviparous Salamander

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We examined clinal gradients in reproductive modes and associated offspring body condition across a hybrid zone between two bimodal viviparous subspecies of Salamandra salamandra. We found a clear cline in reproductive modes, with pure modes at the extremes and mixed modes in central populations.

Exploring adaptive introgression in modern human circadian rhythm genes

AbstractInterbreeding between modern humans and archaic hominins, including Neanderthals and Denisovans, occurred as modern humans migrated outside of Africa. Here, we report on evidence of introgression from archaic hominins within genomic regions associated with circadian rhythm and chronotype using 76 worldwide modern human populations from the ...

Lithic Miniaturization Provides a Signature of an MIS4‐3 Southern Dispersal of Homo sapiens

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Fossil and artefactual evidence shows Homo sapiens in Eurasia well before 75 ka. However, genetic evidence suggests all extant non‐African populations derive almost all of their ancestry from a dispersal that only diverged in the last 60–50 ka. In northern Eurasia, the Upper Paleolithic with its laminar blade knapping provides an archeological

Genetic Diversity and Relationships Among Newly Developed Cowpea Mutant Lines Using SSR Markers and Agro‐Morphological Traits

Legume Science, Volume 8, Issue 1, March 2026.
ABSTRACT Cowpea (Vigna unguiculata [L.] Walp.) is a drought‐resilient and protein‐rich legume of major importance in arid and semiarid regions, including Eswatini, where it contributes to food, feed, and nutritional security. The objective of this study was to assess the genetic diversity and relationships among 30 cowpea genotypes, comprising 24 ...

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

Nordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids

New Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.
