Variações na estrutura da comunidade zooplanctônica próxima a usina I da Central Nuclear Almirante Álvaro Alberto (C.N.A.A.A.) - (Angra Dos Reis-R.J.-Brasil) - Ciclo 1980/81 E 1991/93

摘要: During the years of 1980/80 was performed a ecological study in Ribeira Bay (Angra dos Reis-R.J.-Brazil) order to provide informations about planktonic community pre-operational conditions, region Admiral Alvaro Aberto Nuclear Power Plant (C.N.A.A.A.). After 10 activities zooplankton material obtained vertical hauls with net 150 μm at two fixed points (Piraquara de Fora Cove and Itaorna Beach) associations related environmental variables comparing anterior study. The evolution showed sazonal variation dominance holoplanktonic organisms. Copepoda its greatest growth during autumn winter. summer spring relative abundance suffered progressive diminution when Cladocera passed be more representative organisms without competition between its. presented by raining period that fall region.
