Phylogenetic Conservatism and Ambient Temperature Shape Spatial Variation in Bat Occupancy and Species Richness Along a Subtropical Elevational Gradient. [PDF]

Ecol Evol
We investigated how ecological traits and evolutionary history influence the occupancy of 27 bat species along a 1300 m elevational gradient in subtropical Brazil. While ecological traits poorly predicted species' responses, occupancy varied with temperature in a phylogenetically conserved manner, suggesting that elevational niches in bats may be ...

Structure and Tree Diversity in a Mixed Ombrophilous Forest Remnant, Southern Brazil

Floresta e Ambiente, 2021
This study aimed to determine the tree structure, floristic composition and species diversity in the Araucaria State Park, southern Brazil. We allocated 100 plots of 100 m2 (1 ha) each one, and we recorded all trees with diameters at breast height ≥ 5 cm.
