Microscopic organisms drive critical ecosystem functions in lakes, yet their biodiversity remains largely invisible and understudied in the face of climate change.

A study of the Omo-Turkana Basin reveals 79 native fish species but highlights threats from hydrological modifications, illegal fishing, and cross-border conflicts affecting local livelihoods.

Tongyao Pu models the stratification and redox chemistry of meromictic lakes, using hydrodynamic simulations to understand how physical conditions drive chemical changes in freshwater systems.

Research in southwestern Ontario headwater streams compares sampling methods, finding that D-framed sweep nets capture greater macroinvertebrate diversity than petite ponar grabs.

Kerry Caslow manages long-term water quality monitoring at Old Woman Creek, contributing to a dataset spanning over 40 years to understand nutrient processing in Lake Erie's estuary.

A new accessible database documents native aquatic species in the Great Lakes, supporting researchers, managers, and citizen scientists with identification guides and distribution data.

Freshwater ecosystems face an emergency requiring immediate action to bend the curve of biodiversity loss through six priority recovery actions.

Jacob Cianci-Gaskill works as an application development manager, helping scientists worldwide utilize water quality sensors and technologies for field deployments and data analysis.
