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.

Unravelling the Intraspecific Variation in Drought Responses in Seedlings of European Black Pine (Pinus Nigra J.F. Arnold)

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.

Biases and Uncertainties in Radiosonde‐Based Precipitable Water Vapor

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Precipitable water vapor (PWV) plays an important role in weather and climate phenomena. Accurate PWV measurements based on radiosonde observations are essential for assessing remote‐sensing measurements and long‐term trends. This study examines the performance of PWV algorithms, including their intrinsic biases and their sensitivity to ...

A Field Guide for Soil Erosion Risk Assessment in Olive Orchards Across Mediterranean Conditions for End‐Users and Stakeholders

Land Degradation &Development, Volume 37, Issue 13, Page 9202-9221, 15 August 2026.
ABSTRACT Soil erosion control poses a crucial challenge to the sustainability of Mediterranean olive groves. To facilitate field‐level decision‐making, we have developed a field guide oriented to use in any type of olive orchard across the Mediterranean.

Extreme weather events cause pulsed fruit drop and alter plant–seed disperser mutualisms

Journal of Ecology, Volume 114, Issue 8, August 2026.
Extreme weather events are increasing in frequency, duration and intensity, yet their role in reshaping plant–frugivore interactions remains poorly understood. We show that extreme weather events trigger abrupt pulses of fruit drop, redistributing interaction opportunities among ground‐dwelling frugivores.

EDAFOCLIMATICS VARIABLES ASSOCIATED TO DESERTIFICACIÓN

Tropical and Subtropical Agroecosystems, 2010
Desertification is a land degradation process generated by climatic variations and human activities. Mexico evidences a 64 % of degraded land, caused by deforestation, overgrazing, and change of land use. The aims of this research were to determine the degree of desertification of agricultural watershed in Baja California Sur and to correlate it with ...

Habitat‐based spatial patterns enable realistic reconstruction of plant spatial arrangements across complex landscapes

Oikos, Volume 2026, Issue 7, July 2026.
Spatially explicit individual‐based models provide a powerful way to explore spatial dynamics when direct observation is not feasible. But for many ecological applications, these models require detailed data on the initial spatial arrangement and traits of individuals – information rarely available in large, heterogeneous or novel landscapes.
