Strong Variation in Land‐Use Change Impacts on Tropical Avian Phylogenetic Diversity Between Ecoregions Highlights the Need to Sample Large Spatial Scales

Global Change Biology, Volume 32, Issue 1, January 2026.
Forest conversion for agriculture is a major cause of biodiversity loss in the tropics, but its impacts depend on how broadly they are measured. Using data from across Colombia, one of the most biodiverse countries in the world, we examined how deforestation for cattle farming affects the evolutionary history of bird species.

Wetland location and captive breeding influence trans‐Mediterranean movements in the endangered Marbled Duck (Marmaronetta angustirostris)

Ibis, Volume 168, Issue 1, Page 245-258, January 2026.
Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.

Quantifying Atmospheric Humidity in the Western Mediterranean During the Iron Age and the Roman Era

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Atmospheric moisture is a key hydroclimatic parameter that influenced ancient societies, agriculture, and ecosystems. However, quantitative constraints on pre‐industrial atmospheric humidity values are rarely available. Here, the triple oxygen (17O/16O and 18O/16O) and hydrogen (2H/1H) isotope compositions of lacustrine gypsum are used to ...

Temporal field phenomics of transgenic maize events subjected to drought stress: Cross‐validation scenarios and machine learning models

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Global climate change has driven breeding programs to develop abiotic stress‐resilient plant varieties. Traditionally, assessing drought resilience involves labor‐intensive and time‐consuming processes. This study used an unmanned aerial system (UAS) to predict key phenotyping traits in maize (Zea mays L.) and monitor plant response to drought

Evaluating protected areas’ coverage of threats to terrestrial biodiversity

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...
