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 ...

Unravelling the drivers of island species richness in tropical savannas

Journal of Ecology, Volume 114, Issue 4, April 2026.
Murundu island area explains a substantial proportion of the variation in tree and herb richness, consistent with Island Biogeography Theory. On average, a 10% increase in island size corresponds to increases of seven tree species and 7.8 herb species.

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.
