Land Cover Change Drives River Flow Modifications in Central Chile

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
This study examines the combined effects of land cover change and ENSO on streamflow dynamics in four coastal catchments of central Chile, using a 45‐year (1979–2023) dataset of remote sensing and hydroclimatic data. Conclusions Native forest loss reduced summer flows and PP–Q relationship; preserved forests enhanced resilience.

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, Volume 2026, Issue 5, May 2026.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

Data gaps and heterogeneity limit our understanding of human–wildlife interactions: A continental study of Andean bears

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1499-1519, May 2026.
Abstract The expansion and intensification of human activities have increased interactions between people and wildlife. Interactions involving bears and other large carnivores are complex and can lead to conflicts. Promoting positive coexistence requires managing information, which is not always available.

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1475-1490, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Cenozoic Time Constraints on the Evolution of a Gleysol‐Ferralsol‐Podzol Toposequence, Northwest Amazon Basin, Brazil

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Deciphering the time milestones of clay formation is crucial for modeling the evolution of major geological systems near the Earth's surface. In the present study, kaolinite samples collected along four vertical profiles within a Gleysol‐Ferralsol‐Podzol soil toposequence near São Gabriel da Cachoeira, NW Amazon Basin (Brazil) are dated using ...

Roles of Surface Latent Heat Flux and Gravity Waves in Offshore MCS Development in the Coastal Eastern Tropical Pacific

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The eastern tropical Pacific (ETP) coastal region, one of the rainiest places on Earth, is characterized by distinct diurnal offshore rainfall propagation primarily driven by mesoscale convective systems (MCSs). Previous studies have shown that MCS initiation in this region peaks in the early morning, with diurnally generated gravity waves ...
