Aquatic vegetation provides many services for aquatic habitats and fish communities. The federally listed fountain darter Etheostoma fonticola, found only in spring systems of the San Marcos and Comal rivers in central Texas, is reported to associate

To accommodate for human population growth along the Texas I-35 corridor, land is becoming increasingly urban and decreasingly pervious, modifying the infiltration and runoff rates in the Edwards Aquifer, especially to its spring fed Upper San Marcos

Turbidity levels in rivers increase from changes in water flow or high recreational use, which reduces visibility and affects the use of visual cues by aquatic organisms. Decreased visibility affects time spent associating with conspecifics and stren

Increased turbidity and the resulting decreases in water clarity have been shown to alter fish foraging behaviors in potentially detrimental ways. Given the ecological importance of darters of the genus Etheostoma and their dependence on visual cues,

The endangered fountain darter Etheostoma fonticola is found only in the Comal and San Marcos rivers in the Guadalupe River basin in central Texas, USA. Comal River fountain darters were believed to be extirpated following a severe drought in the 195

The fountain darter Etheostoma fonticola is a federally endangered species that is associated with primarily clear, spring-fed systems, suggesting even minor changes in turbidity have the potential to affect behavior. We examined the effects of turbi

Behavioral interactions between individuals of the same sex can affect the outcome of intersexual selection. For this reason, intrasexual selection is oftentimes examined independently from intersexual selection in studies aimed at understanding mati

We quantified site fidelity, directionality and magnitude of movement, and factors associated with movement of the endangered Fountain Darter Etheostoma fonticola, a narrowly distributed ( 55%), and among larger fish (>30 mm TL). Maximum distance mov

The Edwards Aquifer in south-central Texas, U.S.A. is recognized worldwide for its aquatic species of flora and fauna, many of which are endangered or threatened, and also is the sole water source supporting the industrial, agricultural, municipal, a
