Plant functional types broadly describe water use strategies in the Caatinga, a seasonally dry tropical forest in northeast Brazil. [PDF]

open access: yesEcol Evol, 2021
Plant functional types in the Caatinga seasonally dry forests can be defined according to phenology and wood density. Our work demonstrates that there is a tight correspondence between these plant function types and water use strategies. Abstract In seasonally dry tropical forests, plant functional type can be classified as deciduous low wood density ...

Isolation, Purification, and Characterization of Homogenous Novel Bioactive Protein from Datura stramonium Stem Exhibited Larvicidal Activity against Anopheles stephensi. [PDF]

open access: yesJ Trop Med, 2022
The insecticidal resistance of mosquitoes necessitates the development of a natural, safe, and plant‐based method for vector control. Unfortunately, there are no effective vaccines or particular medications available to combat malaria; therefore, mosquitoes must be targeted directly. Previous studies have shown the health benefits of Datura stramonium,

Litter Dynamics and Nutrient Stocks in a Chronosequence of Hyperxerophilous Forest Under the Effect of Clear Felling. [PDF]

open access: yesEcol Evol
We investigated litter accumulation and nutrient stocks across a forest regeneration chronosequence in hyperxerophilous Caatinga following clear‐cutting. Using multivariate statistics and structural decomposition indices, we identified functional litter profiles and their association with nutrient cycling and soil resilience. Our findings highlight how
