TL;DR: Using 835 inventories covering 4660 species of woody plants, marked floristic turnover among inventories and regions indicates that numerous conservation areas across many countries will be needed to protect the full diversity of tropical dry forests.

TL;DR: It is shown that cacti are among the most threatened taxonomic groups assessed to date, with 31% of the 1,478 evaluated species threatened, demonstrating the high anthropogenic pressures on biodiversity in arid lands.
Journal ArticleDOI
Comparative pollination biology of Venezuelan columnar cacti and the role of nectar-feeding bats in their sexual reproduction.
TL;DR: The pattern of floral visitation through the night was significantly correlated with the pattern of nectar production and nectar sugar concentration for all species of cactus, and the hypothesis that Venezuelan species of columnar cacti have evolved toward specialization on bat pollination is supported.
Journal ArticleDOI
Need for Integrated Research for a Sustainable Future in Tropical Dry Forests
G. Arturo Sánchez-Azofeifa,Margaret Kalacska,Mauricio Quesada,Julio Calvo-Alvarado,Jafet M. Nassar,Jon Paul Rodríguez +5 more
TL;DR: The lack of conservation effort in tropical dry forests is reflected in the fact that few national parks and biological reserves protect and preserve their natural richness, and there are only a handful of real biological research stations with a mandate to bridge the gap between ecology and conservation biology in these ecosystems as discussed by the authors.
