freshwater-ecology
Freshwater ecology studies the biological communities and ecological processes within lakes, rivers, wetlands, bogs, and other inland water bodies. For plant science, these habitats are critical environments where aquatic and semi-aquatic plants play foundational roles in nutrient cycling, oxygen production, and ecosystem structure. Understanding how plants adapt to and shape freshwater systems informs research on wetland conservation, water quality, and the responses of aquatic vegetation to environmental change.

A green alga called Closterium acerosum was spotted in a freshwater habitat in Upper Marlboro, Maryland. This citizen-science sighting adds to the known distribution of this microscopic organism in the mid-Atlantic region.
Research-grade observation of Closterium acerosum confirmed in Upper Marlboro, MD, contributing a verified data point to its mid-Atlantic range map.
The sighting was classified as research-grade, meaning it met iNaturalist's community identification standards with photographic evidence.
Closterium acerosum is a desmid (a type of green microalga) typically found in clean, slightly acidic freshwater habitats, suggesting suitable water conditions at this site.
