Climate‐driven resource availability drives medium‐ and broad‐scale temporal changes in owl–prey interactions over 24 years in a semi‐arid ecosystem

Ecography, EarlyView.
Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Weed flora in forage maize fields as an attraction for entomophagous insects

Egyptian Journal of Biological Pest Control
Background Phytosanitary problems, particularly insect pests, frequently threaten forage maize crops. However, spontaneous weed flora associated with these crops may provide key ecological functions by hosting entomophagous insects that contribute to ...

Long-term hydrological monitoring in arid-semiarid Almería, SE Spain. What have we learned?

Cuadernos de Investigación Geográfica, 2018
A combination of high temporal variability and spatial heterogeneity of rainfall, soil surfaces, and plant cover is the cause of the complex hydrological response in arid/semiarid regions.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Trait variation driven by tree size more than environment and shows limited translation to species vital rates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits are expected to predict vital rates and performance outcomes because they mediate how organisms interact with the environment. However, trait‐based models often have poor predictive power for tree species survival and growth.

A framework for integrating resilience indicators into risk assessments

Conservation Biology, EarlyView.
Abstract Globally, ecosystems are increasingly threatened by climate change and human pressures, yet ecosystem risk assessments predominantly emphasize exposure to stressors while overlooking intrinsic ecosystem resilience—the capacity to absorb and recover from disturbances.

Local Elites in Chile's Pisco Valley: Dispossession, Legal Mobilisation and Intertwined Citizenship

Journal of Agrarian Change, EarlyView.
ABSTRACT In countries in the Global South, citizenship is often closely tied to access to water and land ownership. In Latin America, the literature has primarily explored social mobilisation and identity reconfiguration in response to development‐driven processes of land and water dispossession affecting peasants, rural and Indigenous communities ...

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, Volume 2026, Issue 8, August 2026.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Reproduction reduces HSP70 expression capacity in Argopecten purpuratus scallops subject to hypoxia and heat stress

Aquatic Biology, 2015
In scallops, gonad production is highly demanding energetically, and reproduction usually occurs during spring-summer, a period of strong environmental changes.

A Next‐Generation Snow Albedo Parameterization for Climate Modeling Using Constrained Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We demonstrate a data‐driven parameterization framework for snow albedo evolution using a constrained auto‐regressive neural differential equation that directly predicts snow albedo change from standard meteorological inputs. After training with multi‐year in situ and satellite observations from a wide variety of locations, the scheme ...
