The Scent Gland Microbiomes of Wild Tamarins Provide New Insight Into Microbial Contributions to Olfactory Communication. [PDF]

Ecol Evol
Our study investigated the microbiomes of suprapubic and sternal scent glands in two wild tamarin species to explore their putative roles in odor production and communication. Using metagenomic sequencing, we identified 18 odor‐associated microbial taxa and 26 related metabolic pathways, finding significant differences in microbial diversity and ...

Tropical Montane Cloud Forests Have High Resilience to Five Years of Severe Soil Drought. [PDF]

Glob Chang Biol
A 5‐year throughfall exclusion experiment in a Peruvian tropical montane cloud forest reduced soil moisture by 69%, leading to lower photosynthetic inputs and autotrophic respiration but maintaining net primary productivity and carbon sink capacity. Trees responded through metabolic downregulation, reduced fruit production, increased wood density, and ...

Mother's smoking habits affects IL10 methylation but not asthma in Ecuadorian children. [PDF]

Mol Genet Genomic Med
In our study conducted in Cuenca‐Ecuador, we explored IL10 gene methylation and its association with asthma among children aged 5–11. While no significant differences in IL10 methylation profiles were observed between asthmatic and non‐asthmatic children, a notable link was found between mothers' smoking habits and alterations in the IL10 methylation ...

Employing a Hysteresis Approach to Analyze Shifts in Tree Physiological Thresholds in Response to Drought. [PDF]

Plant Cell Environ
ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.

Tailoring evidence into action: Using a co‐design approach for biodiversity information in the Tropical Andes

Conservation Science and Practice, Volume 5, Issue 12, December 2023., 2023
Our study presents a co‐design approach to improve biodiversity information flow in the Tropical Andes. Through stakeholder engagement and collaborative workshops, we identified priority needs and co‐designed user‐relevant indicators, addressing data gaps and enhancing inclusivity. Our approach offers a valuable framework for mainstreaming biodiversity
