Environmental DNA succeeds in detecting a low‐density population of endangered harlequin frogs
Conservation Science and Practice, Volume 8, Issue 10, October 2026.This work evaluates the use of environmental DNA (eDNA) to detect the Critically Endangered Jambato Harlequin Frog (Atelopus ignescens)—an iconic species once thought extinct and now known only from a single locality in the Ecuadorian Andes. Our study demonstrates the effectiveness of eDNA in detecting the Jambato in a low‐density amphibian population,

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree
PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1904-1924, September 2026.Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Plant, Cell &Environment, Volume 49, Issue 8, Page 4850-4871, August 2026.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.
