Zooplankton Community Composition in Floodplain Lakes of Caura River, Venezuela
Four floodplain lakes (Chuapo, Naparaico, Brava and Aricagua) on the lower basin of the Caura River, Venezuela were analyzed regarding composition of the zooplankton. Samples were collected monthly from March 1998 to February 2000. At each site, composite water samples were filtered through a 60-μm...
