1. Advances in the knowledge of the natural history of aquatic plants in the Neotropics
ABSTRACT Until the mid-XX century, little awareness on the ecological services or socio-environmental problems and benefits related to aquatic plants culminated in bottlenecks on their natural history, especially for the Neotropics. In this context, Acta Botanica Brasilica (ABB) organized this special issue to promote the advancement of knowledge on this eco

3. Global panorama of studies about freshwater oligochaetes: main trends and gaps
Abstract Freshwater oligochaetes have been studied over the years in a wide range of habitats around the world. To analyse the data published about freshwater oligochaetes in the 31 year period between 1985 and 2015, we searched for documents in the ISI Web of Science, Scopus and SciELO databases. A total of 979 works were evaluated from 184 periodicals. The

4. Relative growth, sexual dimorphism and morphometric maturity of Trichodactylus fluviatilis (Decapoda: Brachyura: Trichodactylidae) from Santa Terezinha, Bahia, Brazil
Freshwater crabs are important elements in the aquatic biota of brooks, rivers, lakes and ponds, from both ecological and the socio-economic aspects. Trichodactylidae comprises 51 endemic species from the Neotropical region. Among all the species of this family, Trichodactylus fluviatilis Latreille, 1828 has the widest geographic distribution throughout Braz

5. Estrutura populacional, crescimento somático e alométrico, biologia reprodutiva e estimativa do tamanho populacional de Aegla perobae Hebling &Rodrigues, 1977 do município de São Pedro, estado de São Paulo / Population structure, somatic and allometric growth, reproductive biology and population size estimation of Aegla perobae Hebling &Rodrigues, 1977 in São Pedro, São Paulo state
Aeglids are endemic to the neotropical South America. They are restricted to freshwaters, mainly occurring under rocks and fragmented leaves or buried in the sand (Burns, 1972; Rodrigues &Hebling, 1978; Swiech-Ayoub &Masunari 2001a) in lakes, rivers, streams and even rivers running into caves. The aeglids are important links in the food chain of freshwater e

6. Estrutura populacional e alometria reprodutiva de Podocnemis expansa (Testudines, Podocnemididae) no entorno do Parque Nacional do Araguaia, Tocantins / Population structure and reproductive allometry of Podocnemis expansa (Testudines, Podocnemididae) around the Parque Nacional do Araguaia, Tocantins
Among the reptiles found in the Amazon, the turtles stand out because of its diversity and economic importance. Podocnemis expansa, popularly known as Amazon river turtle, is considered the largest freshwater turtle in South America and has been heavily exploited for centuries by many indigenous and riverine communities. This study aimed to expand the knowle

7. Avaliação da estrutura genética do surubim, Pseudoplatystoma corruscans (Actinopterygii: Siluriformes) como subsídio para o repovoamento do submédio São Francisco
The São Francisco River is 2700 km long, draining areas of the States of Minas Gerais, Goias, Bahia, Pernambuco, Alagoas, and Sergipe, as well as part of the Federal District. Before the construction of Paulo Afonso Hydroeletric Power Plant, waterfalls of Paulo Afonso (north-eastern Brazil) and its respective lakes already constituted a natural obstacle to

8. The effect of temperature on the reproduction of Limnodrilus hoffmeisteri (Oligochaeta: Tubificidae)
The tubificid worm Limnodrilus hoffmeisteri Claparede, 1862 is widely used as an indicator of organic pollution in aquatic environments. Nevertheless, little is known about its biology. The present work aimed to compare the reproductive rate of L. hoffmeisteri raised at three different temperatures (15, 20 and 25°C). Seventy-five adult individuals were kept

9. Composition and trophic structure of fish communities in the Ribeirão Bananal sub-basin, Parque Nacional de Brasília, biome Cerrado, DF / Composição e estrutura trófica da comunidade de peixes de riachos da sub-bacia do Ribeirão Bananal, Parque Nacional de Brasília, bioma Cerrado, DF
The purpose of this study was determined the composition and the trophic structure of fish communities in the Ribeirão Bananal sub-basin, which belongs to a well preserved Cerrado area in the National Park of Brasília, Brazil. Furthermore, due to a marked sazonality in this biome, it was examined the influence of environmental variations on the fish specie

12. Encalhes de Cetáceos ocorridos no período de 1984 a 2005 no litoral do Rio Grande do Norte, Brasil
Strandings of live or dead aquatic mammals constitute an important instrument to provide information regarding the occurrence, biology and ecology of these species. The aim of this study was to register the stranded species of cetaceans, the frequency and the spatial-temporal distribution of theses strandings during the period of 1984 to 2005, in the coast o
