Water scarcity is a growing concern in Texas, where surface water is derived almost entirely from rainfall. Changes in air temperature and precipitation patterns associated with global climate change are anticipated to regionally affect the quality and quantity of inland surface waters and consequently their suitability as habitat for freshwater life. In addition to directly affecting resident organisms and populations, these changes in physicochemical traits of aquatic habitats may favor the establishment of harmful invasive species. As conflicts over the use of water resources grow in intensity, this information will become important for fish and wildlife managers to anticipate impacts of climate change on trust...

The Midwest United States is facing wetter winters and springs and more variable precipitation in the summer and fall. Heavy floods and prolonged droughts are costly to agriculture, housing, transportation infrastructure, and recreational opportunities across the region. These extremes also stress the health of freshwater ecosystems that are important to the regional economy and quality of life. The number of freshwater invertebrates like mussels, crayfish, and aquatic insects are generally declining which strongly indicates declining freshwater health. Losing these animals limits benefits such as water purification, food for wildlife, and aesthetic values. This project seeks to understand and synthesize information...

Our approach will include sampling a wide range of habitats and environmental conditions throughout the middle and lower Pecos River basin, across an 18 month time-span to account for seasonal and phenological events. We will utilize a suite of univariate and multivariate statistical techniques to relate occurrence and density of golden alga to environmental factors and other co-occurring organisms. The proposed research will benefit managers of the Pecos River, of its associated reservoirs and unique habitats (sinkholes on the Bottomless Lakes State Park and Bitter Lakes National Wildlife Refuge), and of its resident aquatic biota by identifying specific water quality attributes that promote golden alga bloom development...

REPORT PROJECT BACKGROUND: Golden alga (Prymnesium parvum) is a harmful algal species that is primarily found in marine ecosystems but is also present and invasive in brackish inland waters. The first documented bloom of golden alga in the United States occurred in the Pecos River in 1985. This species has since invaded other water bodies in the Pecos River basin (e.g. sinkhole habitats, reservoirs) and has been reported in at least 23 U.S. states. Toxins produced by golden alga can be lethal to fishes, bivalves, crayfish, and gilled amphibians. The ecological and economical impacts of golden alga blooms have been severe. Recent research suggests that the frequency and severity of golden alga blooms will increase...
