Data from: A reevaluation of the Andean Genus Petroravenia (Brassicaceae: Thelypodieae) based on morphological and molecular data

Diego L. Salariato, Fernando O. Zuloaga & Ihsan A. Al-Shehbaz
Abstract Petroravenia was until recently considered as a genus of three species (P. eseptata, P. friesii, and P. werdermannii) distributed along the Central Andes of Argentina, Bolivia, Chile, and Peru. This genus was included in the tribe Thelypodieae and was morphologically characterized by being tiny rhizomatous perennial herbs with rosulate leaves, dendritic trichomes, capsular silicles, and incumbent cotyledons. However, the phylogeny of Petroravenia, and its tribal placement, was never analyzed using molecular data. The lack...

Extinct plants of North America north of Mexico

The recent study by Humphreys et al., reporting extinction of almost 600 plant species globally, represents a groundbreaking effort at compiling direct data on seed plants. We applaud Humphreys et al. for quantifying plant extinctions because they formulate an important and testable hypothesis. However, their study missed many extinctions and rediscoveries of seed plants in the United States and Canada. Our team of experts has been compiling a list of extinct plants of North America...

Environmental correlates of Leguminosae species richness in Mexico: quantifying the contributions of energy and environmental seasonality

Maribel Arenas-Navarro, Oswaldo Téllez-Valdés, Gabriel López-Segoviano, Miguel Murguía-Romero & Sebastián Tello
Explaining species richness patterns is a central issue in ecology, but a general explanation remain elusive. Environmental conditions have been proposed to be important drivers of these patterns, but we still need to better understand the relative contribution of environmental factors. Here we aim at testing two environmental hypotheses for richness gradients: energy availability and environmental seasonality using diversity patterns of the family Leguminosae across Mexico. We compiled a database of 502 species and 32,962...
