1 Introduction It has been discussed for decades whether species occur most frequently or abundantly at their geographic center, and more recently, at their environmental niches' center (Dallas et al. 2017; Soberón et al. 2018; Fristoe et al. 2023). Species, including tree species, are adapted to environmental conditions (Flood and Hancock 2017); consequently, species are expected to have preferred points or intervals on unidimensional environmental gradients (Toledo et al. 2012).

Pleistocene climatic oscillations, characterized by arid (interglacial) and pluvial (glacial) phases, have profoundly impacted the floras of Mediterranean climates. Our study investigates the hypothesis that these climatic extremes have promoted phases of range expansion and contraction in the Eriosyce sect. Neoporteria, resulting in pronounced genetic structuring and restricted gene flow.

1 INTRODUCTION Water is transported through the xylem from the soil to the evaporating surfaces in the leaves. This upward movement of water against gravity is driven by a water potential gradient between the soil and the leaves (Dixon & Joly, 1895). During drought, the formation of embolism blocks the water flow through xylem conduits.
