Panama Canal expansion and shifts in fishing practices: A social‐ecological network approach

People and Nature, Volume 8, Issue 5, Page 1520-1532, May 2026.
Abstract Species introductions have spiked over the past two centuries due to globalization. These introductions impact ecosystems, but may also have long‐term implications for human communities. In one of the world's hubs for global shipping, the Panama Canal, a recent canal expansion has coincided with an increase in marine fishes entering the ...

Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences
