A Plant‐Diversity Dark Spot at the Intersection of Three Biodiversity Hotspots: Environmental Drivers of Brassicaceae Richness in Türkiye

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Türkiye lies at the intersection of three global biodiversity hotspots yet is recognised as a global plant‐diversity "dark spot." Using > 15,000 georeferenced herbarium records and spatial regression models, we examined the environmental drivers of Brassicaceae species and endemic richness across the country. Species richness increased with topographic

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.

Pressure of Invasive Alien Species Trachemys scripta on Native Species Under Future Climate Change Scenarios

Ecology and Evolution, Volume 16, Issue 2, February 2026.
In this study, ecological niche models are provided for Trachemys scripta and its competing species in Turkey. In 20‐year intervals, the map indicates the future habitat areas suitable for the invasive species as well as its competitors. The results of this study have led to a determination of the regions where invasive species are likely to be ...
