Article Synopsis
  • Alexander von Humboldt's observations in the Neotropics led him to propose that climate influences plant diversity along elevational gradients, particularly in his explorations across Mexico.
  • The study focused on the Cofre de Perote mountain, assessing how climatic factors and forest-use intensity affected the species richness and phylogenetic structure of angiosperms, revealing that temperature is the main predictor of diversity.
  • Findings emphasize the unique responses of different plant life forms to environmental variables and highlight the negative impact of forest-use intensity on the diversity of tree species, underscoring the importance of integrating Humboldt's biogeographic methods in current environmental research.

The Bromeliaceae family has been used as a model to study adaptive radiation due to its terrestrial, epilithic, and epiphytic habits with wide morpho-physiological variation. Functional groups described by Pittendrigh in 1948 have been an integral part of ecophysiological studies. In the current study, we revisited the functional groups of epiphytic bromeliads using a 204 species trait database sampled throughout the Americas.

Background: This data paper describes a new, comprehensive database (BIOVERA-Epi) on species distributions and leaf functional traits of vascular epiphytes, a poorly studied plant group, along gradients of elevation and forest-use intensity in the central part of Veracruz State, Mexico. The distribution data include frequencies of 271 vascular epiphyte species belonging to 92 genera and 23 families across 120 20 m × 20 m forest plots at eight study sites along an elevational gradient from sea level to 3500 m a.s.

Target capture has emerged as an important tool for phylogenetics and population genetics in nonmodel taxa. Whereas developing taxon-specific capture probes requires sustained efforts, available universal kits may have a lower power to reconstruct relationships at shallow phylogenetic scales and within rapidly radiating clades. We present here a newly developed target capture set for Bromeliaceae, a large and ecologically diverse plant family with highly variable diversification rates.
