Oviposition behavior is not affected by ultraviolet light in a butterfly with sexually-dimorphic expression of a UV-sensitive opsin. [PDF]
Ecol Evol, 2023 Our study focuses on the evolution of sexual dimorphism of UV vision in Heliconius butterflies. Under naturalistic light conditions, we experimentally altered UV‐light availability using light filters to test the hypothesis that, in H. erato, UV vision is important for oviposition, a female‐specific behavior.

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