Clarifying the trophic state concept to advance macroscale freshwater science and management

Ecosphere, Volume 16, Issue 9, September 2025.
Abstract For over a century, ecologists have used the concept of trophic state (TS) to characterize an aquatic ecosystem's biological productivity. However, multiple TS classification schemes, each relying on a variety of measurable parameters as proxies for productivity, have emerged to meet use‐specific needs.

An Atmospheric Predictor to Estimate the Atmospherically Induced Water Level at Coasts With A Shallow Continental Shelf

International Journal of Climatology, Volume 45, Issue 11, September 2025.
A methodology to define an atmospheric predictor to estimate the total water level at the coast and that accounts for the storm surge generated in remote regions is presented through an application in the southern coast of Brazil. The skill of the predictor to estimate coastal variables is assessed.

River metabolism regimes across large environmental gradients

Limnology and Oceanography, Volume 70, Issue 9, Page 2718-2732, September 2025.
Abstract Rivers process up to half of the terrestrial organic carbon before it reaches the oceans, playing an essential role in the global carbon cycle. However, little is known of the seasonal and regional patterns of riverine biological activity as most river ecosystem metabolism studies have been carried out at short spatial and temporal scales.
