Abstract
The San Antonio River holds a significant historical and ecological value in Texas. This River has been central to the region's development; supporting agriculture, urban growth, and recreation. This ecological research project focuses on developing techniques used for collecting and sorting freshwater aquatic invertebrates to study the ecological community. The procedures involved identifying, sorting, and counting the aquatic invertebrates by species classification. The aquatic invertebrate's composition in the water will help determine the water quality of this specific part of the river. Bio-indicator indices, including EPT and the Biotic Index, along with alpha and beta diversity analyses, were used to gain a deeper understanding of the macroinvertebrate compositions at each site. Our study focused on 12 taxa ranging from pollution tolerant to pollution sensitive that are representative to the San Antonio River. By studying these taxa, ecologists can assess the impact of pollutants, habitat alterations, and make changes in their conservation efforts, making aquatic insects an essential tool for ecological monitoring and water quality management. This study will offer a unique perspective on the potential long-term effects of extreme weather and urbanization on the waterways and the ecosystems of South Texas.
