Wild cherries, petioles and geography: Response to locational and elevational trends in Türkiye

Widely distributed plants demonstrate a number of anatomical differences that help them adapt to the variable abiotic factors across their ranges, which in turn contributes to intraspecies variation. The genus Prunus L. subgenus Cerasus (Mill.) Focke is distributed across the three major phytogeographical regions (Mediterranean, Euro-Siberian and Irano-Turanian) of Türkiye and on either side of the major geological divide known as the Anatolian Diagonal. According to the Köppen-Geiger climate classification, Türkiye features 10 subclassifications in the arid semi-arid (B), temperate (C) and continental (D) zones. To explore how these affect the variation of this taxonomically complex subgenus, we examined the petiole anatomy of 63 individuals of its 10 species collected from across the country, characterizing their differences on a taxonomic level and investigating geographical and climatic sources of variation. To explore the variation in petiole anatomical characters, we employed mult..., , # Data from: Wild cherries, petioles and geography: Response to locational and elevational trends in Türkiye

Summary

To explore the variation of subgenus Cerasus in Türkiye, we examined the petiole anatomy of 63 individuals of its 10 species collected from across the country, characterizing their differences on a taxonomic level and investigating geographical and climatic sources of variation. To explore the variation in petiole anatomical characters, we employed multivariate linear and logistical regression analyses using altitude and coordinate data, as well as phytogeographical region and position in relation to the Anatolian Diagonal, as independent inputs.

We used seven quantitative (width, height and width/height ratio of petiole and p...,
