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.

Bats ecology in the Dry Tropical Forest of Nariño (Colombia) and some commentaries about their conservation

Revista Peruana de Biología, 2016
Tropical dry forests are considered as threatened ecosystems in Colombia, because they are located in areas with intensive human activities. However, the effects of habitat loss on the distribution and abundance of bats in this region are little known ...

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.

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub

Oikos, Volume 2026, Issue 6, June 2026.
Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...

Evaluating the restoration of plant ecological interactions in gypsum mines with species co‐occurrences analyses

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
These case studies suggest that both seed‐based and seedling‐based approaches can restore pairwise species interactions to a similar extent. The seedling‐based method, although more expensive, provides immediate visual impact by directly introducing canopy‐forming species into the system.
