Reproductive tactics optimizing the survival of the offspring of Cichlasoma ori...
Linhares, Jussiara Candeira Spíndola; Manna, Luisa Resende; Mazzoni, Rosana; Rezende, Carla Ferreira; Silva, José Roberto FeitosaHigh mortality rates have been observed in Teleost during early developmental stages, as well as great variations in reproductive tactics, which are related to adaptations towards environmental conditions and ecological niches for which different species have a specific response. The objective of this study was to describe reproductive tactics related to the survival of Cichlasoma orientale offspring, including...
A multiple hypothesis approach to explain species richness patterns in neotropi...
Vieira, Thiago Bernardi; Pavanelli, Carla Simone; Casatti, Lilian; Smith, Welber Senteio; Benedito, Evanilde; Mazzoni, RosanaSeveral hypotheses are used to explain species richness patterns. Some of them (e.g. species-area, species-energy, environment-energy, water-energy, terrestrial primary productivity, environmental spatial heterogeneity, and climatic heterogeneity) are known to explain species richness patterns of terrestrial organisms, especially when they are combined. For aquatic organisms, however, it is unclear if these hyp...
Large-scale Degradation of the Tocantins-Araguaia River Basin
Pelicice, Fernando Mayer; Agostinho, Angelo Antonio; Akama, Alberto; Andrade Filho, José Dilermando; Azevedo-Santos, Valter M. [UNESP]Made available in DSpace on 2022-04-28T19:42:34Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-10-01; The Tocantins-Araguaia Basin is one of the largest river systems in South America, located entirely within Brazilian territory. In the last decades, capital-concentrating activities such as agribusiness, mining, and hydropower promoted extensive changes in land cover, hydrology, and environmental condit...

Azevedo, Rafael Santos de; Dumas, Leandro; Rodrigues, Daniela; Rezende, Carla Ferreira; Caramaschi, Érica Pellegrini; Mazzoni, Rosana; Nessimian, JorgeComposition, diversity and density of benthic macroinvertebrates were described based on samples from the four different sites of Rio Mato Grosso, Saquarema, Rio de Janeiro. Biotic and environmental data were obtained in January 2006 in microhabitats with different substrates. A total of 5.605 specimens of the 28 insect families and two crustaceous families are sampled. The lowest values of richness, diversity,...

Occurrence of Arcellidae (Amorphea, Arcellinida) in a coastal stream in the Sta...
Miranda, Viviane Bernardes dos Santos; Mantovano, Tatiane; Silva , Yemna Gomes da; Lansac-Tôha , Fábio Amodêo; Mazzoni, RosanaThe aim of this study was to elaborate a taxonomic survey on the testate amoebae of the Family Arcellidae in coastal streams in the State of Rio de Janeiro. Six samplings were conducted in Ubatiba coastal stream (Maricá, RJ). In total, 130 liters water were filtered through a conical net of 60-μm mesh and preserved in 4% formalin. Organisms were identified with the aid of an inverted trinocular microscope. The ...

Testate amoebae (Protozoa Rhizopoda) in two biotopes of Ubatiba stream, Maricá,...
Miranda, Viviane Bernardes dos Santos; Mazzoni, RosanaFour samplings were carried out during the dry and rainy seasons in 2014, in two biotopes (plankton and aquatic macrophytes) to assess the composition and species richness of testate amoebae community in a coastal stream in the state of Rio de Janeiro, Brazil. Results showed great representation of Difflugiidae, Centropyxidae, Lesquereusiidae and Arcellidae families. Higher richness was observed in the plankton...
