TLDR
It is found that plant range sizes are codetermined by habitat area and long- and short-term climate stability, and the joint roles of area and climate stability strengthen concerns over the potential effects of future climate change and habitat loss on biodiversity.Abstract:
Despite being a fundamental aspect of biodiversity, little is known about what controls species range sizes. This is especially the case for hyperdiverse organisms such as plants. We use the largest botanical data set assembled to date to quantify geographical variation in range size for ~ 85 000 plant species across the New World. We assess prominent hypothesised range-size controls, finding that plant range sizes are codetermined by habitat area and long- and short-term climate stability. Strong short- and long-term climate instability in large parts of North America, including past glaciations, are associated with broad-ranged species. In contrast, small habitat areas and a stable climate characterise areas with high concentrations of small-ranged species in the Andes, Central America and the Brazilian Atlantic Rainforest region. The joint roles of area and climate stability strengthen concerns over the potential effects of future climate change and habitat loss on biodiversity.read more

TL;DR: It is shown that additional conservation actions are needed to effectively protect reptiles, particularly lizards and turtles, and that adding reptile knowledge to a global complementarity conservation priority scheme identifies many locations that consequently become important.

Multidimensional biases, gaps and uncertainties in global plant occurrence information
TL;DR: This study provides an empirical baseline for evaluating and improving global floristic knowledge, along with a conceptual framework that can be applied to study other hyperdiverse clades.

TL;DR: A conceptual framework for testing theories for the latitudinal gradient of species richness in terms of variation in functional diversity at the alpha, beta, and gamma scales is presented and suggests that multiple processes have shaped trait diversity in trees, reflecting no consistent support for any one theory.

A network approach for identifying and delimiting biogeographical regions
TL;DR: This work applies a community detection approach from network theory that incorporates complex, higher order presence-absence patterns to tackle the challenges posed by transition zones and succeeds in retrieving a larger number of commonly recognised biogeographical regions.
