Introduction Tropical montane cloud forests (TMCFs) host specialized plant species reliant on persistent atmospheric humidity, including fog immersion obligates and relict assemblages. Understanding anatomical morphological adaptations in TMCF woody angiosperms is critical for elucidating their acclimation strategies to hydric stress under shifting regimes. This study investigates interspecific variability wood leaf traits among 10 tree Mexico’s Medio Monte Natural Protected Area, hypothesizing that distinct emerge response climatic stressors. Methods Wood (e.g., vessel density, hydraulic diameter, fiber length) lamina length, vein organization) were analyzed across species. Traits correlated with variables—mean maximum/minimum temperatures, monthly precipitation, evapotranspiration—to identify adaptive patterns. Statistical analyses quantified differences assessed trait-climate relationships. Results Significant divergence occurred both traits. anatomy was strongly influenced by mean maximum temperature, evapotranspiration, affecting vulnerability index, ray dimensions, length. Leaf temperature extremes driving variation size, apex/base morphology, venation complexity, marginal teeth. Notably, efficiency wider vessels) aligned higher while drought-associated denser veins) linked elevated temperatures. Discussion exhibit trait-based balancing safety efficiency, reflecting niche partitioning microclimatic gradients. Temperature water availability differentially shape adaptations, architecture patterns acting as key regulators of loss. These findings underscore the functional diversity trees capacity acclimate environmental variability. Conservation efforts must prioritize microclimate preservation safeguard these amid climate change.

Background Tropical montane cloud forests contain high levels of epiphyte diversity. Epiphytic tank bromeliads play an important role in the functioning these ecosystems and provide a microhabitat for many species invertebrates. Microbial ecology theory suggests that environment serves as source microbes animals, but contribution this factor to composition animal microbiome varies. In study, we examined extent which ( Tillandsia multicaulis ) serve two fly larvae forest fragment central Veracruz, Mexico. Methods We used 16S rRNA sequencing characterize bacterial communities organic matter within bromeliad tanks whole bodies (surface gut) from taxa Austrophorocera sp., Tachinidae, Copestylum Syrphidae) inhabit bromeliads. To assess larvae, conducted fast expectation-maximization microbial tracking (FEAST) analysis. Results The were primarily composed Pseudomonadota, Acidobacteriota, Bacteroidota, Verrucomicrobiota, Spirochaetota. Similarly, contained Bacillota, Actinomycetota. Bromeliad exhibited highest richness, followed by larvae. Beta diversity analyses indicated clustered species. found modest microbiome, with nearly 30% traced deposited tanks. Conclusions Our data suggest flies, during their larval stage, is nourished some present tank.
