Article: ZOOPLANKTON COMMUNITY STRUCTURE AND SEASONAL DYNAMICS IN LAKE TEXOMA (OKLAHOMA-TEXAS).

Abstract.--Seventy-one species of zooplankton were identified from 16 stations within five zones in Lake Texoma (Oklahoma-Texas) over a 14-month period beginning August 1996. Whole lake mean monthly densities were greatest in mid-May (199.4 org/L) and least in mid-June (83.9 org/L). Mean zooplankton density was a third greater in the Red River arm compared to the Washita River arm and Main Lake zone. Percent composition was similar among the five zones with rotifers making up the largest proportion followed by the nauplii, cladocera, cyclopoid copepods and calanoid copepods. Bray-Curtis Similarity Index at the genus level showed zooplankton community composition was most ...
