A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

open access: yesOikos, EarlyView.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species
