Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

How to reduce avian electrocutions: Insulation or structural changes of dangerous poles

Ecological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
The cost‐effective results of the insulation of dangerous poles were clearly favourable to insolation as a better strategy than the structural design changes to protect the Spanish Imperial Eagles. Abstract Electrocutions of birds in power lines, particularly in distribution power lines, have been a well‐known and widespread global conservation problem

Occupancy and Niche Dynamics of Iberian Freshwater Fish Across 25 Years

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 10, October 2026.
ABSTRACT Global change is reshaping biological communities, leading to shifts in community composition, species distributions and species realized niches. These processes are especially relevant in freshwater ecosystems, where vertebrate declines are particularly severe and dispersal is naturally constrained by drainage basins.

Climatic and Hydrological Changes Drive Contemporary Fire Regime Transitions in the World's Largest Wetland

Global Change Biology, Volume 32, Issue 9, September 2026.
Long‐term fire data (1985–2024) and integrated modeling reveal a climate and hydrology‐driven transition toward larger fires, increased burned area, and a longer fire season, indicating the emergence of a new fire regime in the Pantanal. ABSTRACT Tropical wetlands have historically been resilient to fire, but ongoing climate and hydrological changes ...
