Land use change effects on soil physical-chemical parameters and microbial comm...

Current studies show a decline in soil biodiversity, which puts at risk future food production since soil organisms play a key role in essential ecosystem functions such as, nutrient cycling and soil fertility, soil carbon sequestration, climate regulation, litter decomposition, erosion, water retention, interaction with plants, among others. This study aims to evaluate how the conversion of a tropical native f...

Foliar secretory structures in Crotoneae (Euphorbiaceae): diversity, anatomy, a...

Phylogenetic and morphological studies have helped clarify the systematics of large and complex groups such as the tribe Crotoneae (Euphorbiaceae). However, very little is known about the diversity, structure, and function of anatomical features in this tribe. Crotoneae comprises the species‐rich pantropical genus Croton and six small neotropical genera. Here we characterized the anatomy of leaf secretory struc...
