Outdoor seating in urban areas, such as benches, tables, and café arrangements, can significantly influence the microhabitats of rotifers—tiny aquatic invertebrates vital to freshwater ecosystems. These structures often alter water retention, shade patterns, and organic debris accumulation, creating unique microenvironments.

For instance, shaded areas under seating may reduce evaporation, maintaining stable water levels in puddles or small ponds where rotifers thrive. Conversely, metal or plastic seating can increase surface temperatures, potentially stressing these microorganisms. Additionally, organic matter from food waste or leaf litter near seating areas can enrich rotifer diets but may also introduce pollutants.

Urban rotifers adapt to these changes, but their population dynamics and biodiversity may shift depending on seating density and material. Understanding these interactions helps urban planners design eco-friendly public spaces that support microscopic life while serving human needs. Further research could explore seasonal variations and long-term effects of outdoor furniture on rotifer communities.
