| dc.description.abstract | Research focused upon the structure and function of low elevation, turbid lotic ecosystems is lacking throughout much of the United States. This lack of basic ecological data severely hampers decision makers involving management of freshwater resources. The Navasota River, a low elevation, turbid lotic ecosystem, originates in southeast Hill County and flows approximately 125 miles south to join the Brazos River. Only limited data is available concerning the invertebrate communities and ecological functions these communities contribute to the Navasota River. The purpose of this study is to gain a better understanding of the life cycle and community structure of elmid beetles (Coleptera: Elmidae) in the Navasota River, near where it joins the Brazos River. At least four species of elmids are present in the Navasota River, with adults present in low numbers throughout the year. Larvae are also present throughout the year, but with various size classes. Spring (March and April) appears to be when the majority of larvae transform into adults. | en |
