“…Other researchers, however, have reported lower diversity levels than those encountered in the present study: Reis & Barbosa (1993) encountered only 14 aquatic macrophytes species in Mares Lake in the municipality of Lagoa Santa (MG); Bini et al (2005) identifi ed 16 taxa in the Cachoeira Dourada reservoir (GO/MG); while Pedro et al (2006) reported the occurrence of only nine species while examining the dynamics of macrophyte occupation of reservoirs in the semiarid region of Bahia State.…”

-(Floristic surveys of aquatic macrophytes in reservoirs in the Agreste zone of Pernambuco State, Brazil). We surveyed the aquatic macrophytes in reservoirs in Camocim de São Félix in the Agreste zone of Pernambuco State, Brazil. Plants were collected on a bimonthly schedule from November/2008 to May/2009 in four reservoirs, and 33 taxa distributed among 23 families were encountered. The family Cyperaceae had the greatest number of species, followed by Lemnaceae. The predominant biologic form was emergent (33.3%) refl ecting the extensive shorelines around the reservoirs analyzed.

“…Junto com Eleocharis os gêneros Cyperus, Ludwigia e Polygonum apresentam maior riqueza específica nos levantamentos com plantas aquáticas e palustres. Verifica-se que pelo menos três destes quatro gêneros ocorrem em alguns levantamentos de plantas aquáticas e palustres anteriormente realizados no Brasil (Tanaka et al 2002, Tavares 2003, Bini et al 2005, Delello 2008, Lolis 2008, Martins et al 2008) com excessão de Martins et al (2003), o qual constata a presença somente de Polygonum. Deve ser, ainda, salientado que nos estudos que incluíram espécies anfíbias, os gêneros Cyperus, Eleocharis e Ludwigia tiveram maior riqueza específica (Tavares 2003, Delello 2008, Lolis 2008 Importante destacar que metade das espécies (50,3%) registradas não é considerada daninha ou infestante, sendo uma porcentagem alta, pois as plantas aquáticas e palustres geralmente são vistas dessa forma em ambientes antropizados, como reservatórios, hidrelétricas e outros empreendimentos, devido aos problemas que ocasionam quando ocorre profileração delas.…”

-(Floristic composition of aquatic and palustris plants in the Guarapiranga Reservoir, São Paulo, Brazil). The aim of this study was to investigate the composition of aquatic and palustris plants in the Guarapiranga reservoir, and to contribute to the taxonomic knowledge of the species. Monthly fieldworks were performed from June/2008 to May/2009, in 20 stands of aquatic plants distributed throughout the reservoir. The species present were collected and registered in each stand. The aquatic macrophytes community of the reservoir is composed of 133 species belonging to 89 genera distributed in 45 families being 127 angiosperms, five ferns and one liverwort. The most representative families were Cyperaceae with 27 species, followed by Poaceae (14) and Asteraceae (10). Of the 67 species considered as weeds, only 14 are subspontaneous or naturalized, the other 120 species are native, six of which are endemic in Brazil. The present work contributed significantly to the flora of aquatic plants and palustris of São Paulo, as well as to List of Flora of Brazil, registering species that had not been previously recorded to the state of São Paulo, in this the work is besides a key of identification and descriptions of the species present in the study area. In conclusion, species richness of aquatic plants and palustris at Guarapiranga is high. Key words: Aquatic plants, macrophytes, wetlands, hydrophytes.Resumo -(Levantamento florístico de plantas aquáticas e palustres na Represa Guarapiranga, São Paulo, Brasil) -O objetivo desse trabalho foi verificar a composição de plantas aquáticas e palustres no reservatório Guarapiranga, além de contribuir para o conhecimento taxonômico das espécies. Foram realizadas coletas mensais de julho/2008 a junho/2009, em 20 bancos de plantas aquáticas distribuídos ao longo de todo o reservatório. Em cada banco foram coletadas e registradas as espécies presentes. A comunidade de plantas aquáticas e palustres do reservatório é composta por 133 espécies, pertencentes a 89 gêneros, distribuídos em 45 famílias, sendo 127 de Angiospermas, 5 de Samambaias e 1 de Hepática. As famílias mais representativas foram Cyperaceae com 27 espécies, seguida de Poaceae (14) e Asteraceae (10). Das 67 espécies consideradas plantas daninhas ou infestantes, apenas 14 são subespontâneas ou naturalizadas, as demais 120 espécies são nativas, sendo 6 endêmicas do Brasil. O presente trabalho contribuiu significativamente para a Flora de plantas aquáticas e palustres, bem como para Lista da Flora do Brasil, registrando espécies que não haviam sido referidas anteriormente para o estado de São Paulo, além da apresentação de uma chave de identificação e descrições para as espécies presentes na área de estudo. Foi possível concluir que a Represa Guarapiranga possui uma elevada riqueza de plantas aquáticas e palustres Palavras-chave: plantas aquáticas, macrófitas, alagados, hidrófitas.

“…Macrophytes play a significant role in the hydro ecosystem by providing a breeding substrate for organisms including fish, aquatic insects, and zooplankton and many of them serve as food for fishes (Ratusshnyale 2008). However, in most rivers and lakes the excessive growth of macrophytes may provoke some negative effects (Bini et al 2005), and it develops into explosively large population only when the environment is altered Nigerian inland water bodies serve as an important refuge for numerous animals and vascular plants which have sustained the communities around them. But in recent times, both natural and human-induced environmental problems had either destroyed or altered the associated ecosystem with consequent impact on the endowed natural resources.…”

Abstract. Dienye HE, Olopade OA,. 2017. Distribution and abundance of aquatic plants of Oyan Lake, Ogun State,. Distribution and abundance of aquatic plants from Oyan Lake were assessed bi-monthly between October 2012 and January 2013. In total, 20 species of aquatic plants were recorded representing 13 families. Cyperaceae and Poaceae families had the highest species with four species each. A further result of this study showed that Azolla africana had the highest abundance (richness), followed by Salvinia nymphellula while the species with the lowest abundance (richness) was Ceratophyllum demersum. Ludwigia decurrens and Rhynchospora corymbosa had the lowest in evenness (distribution) followed by Nymphaea lotus. Fimbristylis ferruginea had the highest evenness followed by Echinochloa stagnina. The three most prominent species found at the Stations in order of prominence were: Azolla africana, Salvinia nymphellula and Polygonum lanigerum occupying 42.33% of the area covered by aquatic plants. The biotic indices of species richness, Shannon -Wiener information function, evenness and Simpson's Dominance were fairly distributed in the study area.
