Correlations among chromosome numbers, nuclear DNA contents and climatic variables of South American Cactaceae in a phylogenetic context
Cactaceae are American members of arid and semi-arid regions and are also present in
tropical forests and temperate climates. The taxonomy is complex owing to large …

On the continuum of evolution: a putative new hybrid speciation event in Opuntia (Cactaceae) between a native and an introduced species in southern South America
Hybridization plays a fundamental role in plant evolution and diversification, promoting gene
flow, morphological novelties, and plant speciation. Here, we integrated fieldwork …
