Diverging functional strategies but high sensitivity to an extreme drought in tropical dry forests. [PDF]

open access: yesEcol Lett, 2021
Extreme drought events have negative effects on forest diversity and functioning. We used long‐term demographic records of 21,821 trees and extensive databases of traits to understand the responses of 338 tropical dry forests tree species to an extreme.

The anti-Trypanosoma activities of medicinal plants: A systematic review of the literature. [PDF]

open access: yesVet Med Sci, 2022
Abstract Background The existing drug treatments for trypanosomiases are limited and suffer from shortcomings due to their toxicity and the emergence of resistant parasites. Developing anti‐trypanosomal compounds based on natural products is a promising way of fighting trypanosomiases.

Tiny Patch, Big Value: A Small Dry Forest Patch Supports Wildlife Conservation in Guanacaste, Costa Rica. [PDF]

open access: yesEcol Evol
This study highlights the biodiversity value of the Murren Reserve, a small tropical dry forest patch in Guanacaste, Costa Rica. Using camera traps and opportunistic observations, researchers documented 32 wildlife species, including federally endangered species like the ocelot (Leopardus pardalis) and puma (Puma concolor), as well as 73 plant species.

Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal Optimisation. [PDF]

open access: yesGlob Chang Biol
Many leaf gas exchange models predict that photosynthesis and stomatal conductance are tightly coupled and respond in parallel to changing environmental conditions. However, experiments show that when temperatures increase beyond the thermal optimum of photosynthesis, stomatal conductance may continue to rise while photosynthesis declines, facilitating

Howler monkey foraging ecology suggests convergent evolution of routine trichromacy as an adaptation for folivory. [PDF]

open access: yesEcol Evol, 2017
Primates possess remarkably variable color vision, and the ecological and social factors shaping this variation remain heavily debated. Here, we examine opsin genes, feeding behaviors, and reflectance of dietary foliage of wild mantled howler monkeys (Alouatta palliata).

Local Knowledge and Conservation Priorities of Medicinal Plants near a Protected Area in Brazil. [PDF]

open access: yesEvid Based Complement Alternat Med, 2019
We investigated the influence of socioeconomic factors (age, gender, and occupation) on the local knowledge of medicinal plants in the Araripe National Forest, Brazil, and the priority of conservation of the species as perceived by people. Additionally, priority species for in situ conservation were identified by calculating conservation priority (CP).

Upscaling the effect of traits in response to drought: The relative importance of safety–efficiency and acquisitive–conservation functional axes

open access: yesEcology Letters, Volume 26, Issue 12, Page 2098-2109, December 2023., 2023
Our results demonstrated the complex pathways in which functional traits scale up from individuals to communities in species‐rich tropical forests. Abstract We tested the idea that functional trade‐offs that underlie species tolerance to drought drive shifts in community composition via their effects on demographic processes and subsequently on shifts ...

Metabolomic Analysis and Antioxidant Potential of Tropical Propolis Nonpolar Extracts from Colombia

open access: yesJournal of Food Processing and Preservation, Volume 2023, Issue 1, 2023., 2023
Bioactive compounds of natural matrices are of interest because of their application in the food and pharmaceutical industries. One important source of bioactives is propolis, a resinous biomass that bees make from the plants surrounding the hive. Regarding Colombian propolis, studies have mostly been directed towards identifying flavonoids and their ...
