Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

The Global Airways Unit: A Multidisciplinary Strategy for Early Diagnosis and Comorbidity Detection

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Chronic respiratory diseases impose a large global burden of morbidity, mortality, and cost. The concept of a global airway has become increasingly supported by epidemiologic, mechanistic, and clinical evidence. However, clinical care often remains fragmented between ear, nose, and throat (ENT), allergy, and pulmonology.

Thermoregulation in Heliconius butterflies is determined by habitat association and morphology but not phylogeny

open access: yesJournal of Animal Ecology, EarlyView.
The roles of morphology and phylogeny in thermoregulation were studied in mimetic Heliconius butterflies across habitats. Buffering ability differed among habitats, likely due to morphology. Live heating rate decreased with iridescence and forewing length. No phylogenetic signal was detected.

Enhanced fish detection sensitivity in aquatic systems using environmental RNA

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental RNA (eRNA) can potentially augment the biological monitoring ability of the established environmental DNA (eDNA) application in conservation. Despite faster degradation, environmental RNA could offer unique advantages: it may help reduce the legacy signal compared to eDNA, provide insights into physiological status through gene ...

Seeing both the forest and the trees: An automated workflow for ultra‐high‐resolution drone imaging of tropical canopies

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tropical forest canopies host diverse tree and liana assemblages, yet key foliar and reproductive traits needed for taxonomic identification of canopy plants are often difficult to see from the forest floor, creating a bottleneck in inventories.

A methodological assessment and reflection on member checking as a form of participant validation for conservation social science

open access: yesConservation Biology, EarlyView.
Abstract Qualitative approaches are increasingly applied in conservation social science, yet methodological reflection remains limited. Member checking, a process of returning findings to participants for feedback, is widely recognized outside conservation as a means to enhance rigor and reciprocity, but it is rarely reported in conservation research ...
