Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

Journal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

A multi‐network approach to assess how physical templates shape stream fish ecological strategies

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
This multi‐network framework identifies a continuous topological gradient of fish ecological strategies—comprising Dispersal Gateways, Integrated Connectors, and Mass Effect Dominated species—within the dendritic river template. The functional role of stream reaches is scale‐sensitive, particularly at headwater extremes where sites operate as critical ...

Mammal diversity in the middle basin of the river Tambopata, Puno, Peru

Revista Peruana de Biología, 2011
This study documents the mammalian diversity in the Tambopata River middle basin, one of the most important information gaps in Peru. Five sites were evaluated in Puno (San Fermín 850 m, Curva Alegre 950 m, Challohuma 1200 m, Yanahuaya 1600 m, and ...

Unravelling the spatial and temporal variability of natural disturbances in European forests

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
The heterogeneity of natural disturbance patterns and high temporal variability across European Forest suggest the need of adopting context‐dependent management strategies tailored to both the dominant disturbance agent and local environmental conditions, particularly in the most vulnerable regions, such as the Iberian Peninsula—with large and frequent

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

Journal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.
