1. Avaliação química, ecotoxicológica e genotoxicológica de águas de cavas de mineração a céu aberto
RESUMO Lagos artificiais formados em áreas de mineração a céu aberto são unidades complexas e se constituem em passivos ambientais emergentes advindos da indústria da mineração. Embora estejam aumentando em número em várias partes do globo, são um problema ambiental recente e ainda pouco estudado, especialmente no tocante à qualidade e à toxicid

2. New approaches for growth improvement in pejerrey Odontesthes bonariensis (Valenciennes, 1835) culture (Atherinomorpha: Atherinopsidae)
The pejerrey is the most important recreational species in shallow temperate lakes and reservoirs of Argentina and the attempts to develop its culture have started a century ago. A common constraint of pejerrey aquaculture is its poor growth under traditional intensive rearing techniques. The aim of this study was to evaluate the possibility to achieve and m

3. Yeast diversity associated to sediments and water from two Colombian artificial lakes
In Colombia, knowledge of the yeast and yeast-like fungi community is limited because most studies have focused on species with clinical importance. Sediments and water represent important habitats for the study of yeast diversity, especially for yeast species with industrial, biotechnological, and bioremediation potential. The main purpose of this study was

4. Species richness of the genera Trachelomonas and Strombomonas (pigmented Euglenophyceae) in a subtropical urban lake in the Porto Alegre Botanical Garden, RS, Brazil
The objective of this study was to evaluate the taxonomic composition and richness of the genera Trachelomonas and Strombomonas (pigmented Euglenophyceae) in a subtropical urban lake (30º03'05"S; 51º10'34"W) within the Botanical Garden, in the city of Porto Alegre, located in the state of Rio Grande do Sul, Brazil, in order to contribute to the floristic k

5. Influência de lagos artificiais no clima local e no clima urbano: estudo de caso em Presidente Epitácio (SP) / Influence of artificial lakes in local climate and urban climate: a case study in Presidente Epitácio (SP)
Nas últimas décadas tem sido temática de estudos as alterações realizadas no meio ambiente urbano e as variabilidades climáticas que ocorrem a partir das intervenções, principalmente no que se refere à formação de lagos artificiais para construção de usinas hidrelétricas. As transformações antrópicas de um determinado espaço físico podem o

6. Taxonomia do gênero Callibaetis Eaton, 1881 (Ephemeroptera: Baetidae) no Brasil
The species of the genus Callibaetis Eaton, unlike other members of the family, have been originally described based solely on alate stages, most of them inadequately. Despite the fact that the taxonomy of the family has improved in the last decades, the knowledge of the genus is still incipient. The aim of this study was to survey the species of Callibaetis

7. Influência da morfometria de lagos na diversidade fitoplanctônica
Morphometry is the measurement of various elements of form, and it includes methods to measure since the physical dimensions of an individual to the dimensions of a system. Morphological evaluations are good study mechanisms in many areas of science and work as fundamental tools from a microscopic scale to the dimensions of an ecosystem. In lakes, the unders

8. Variação cariotípica de Astyanax bimaculatus (Linnaeus, 1758) (Pisces: Characidae) nas bacias costeiras do Brasil / Karyotypic variation of Astyanax bimaculatus (Linnaeus, 1758) (Pisces: Characidae) in the coastal basins of Brazil
The genus Astyanax comprises 90 species considered together with most of the old Tetragonopterinae as incertae sedis within the family Characidae. Most of the Astyanax are small, were classified in an artificial taxonomic system and therefore their taxonomic boundaries are poorly defined. Seven coastal populations of one of these species, Astyanax bimaculatu

9. Características limnológicas e estrutura trófica das comunidades de peixes de alguns lagos naturais e artificiais do Rio Grande do Norte
Artificial lakes must differ from natural lakes in important structural and functional aspects that need to be understood so that these ecosystems can be properly managed. The aim of this work was to test the hypothesis that the artificial lakes (impoundments) in the semi-arid region of the Rio Grande do Norte State are more eutrophic and turbid and have dif

10. Life cicle aspects of endemic benthic species and its aplication on the sediment quality assesments of natural lakes and reservoirs / Aspectos do ciclo de vida de espécies bentônicas nativas e sua utilização na avaliação da qualidade de sedimentos de lagos naturais e reservatórios
The ecological studies, with views for the conservation of the environment, have been intensified from middles of the century XX. Due to the integration with several other sciences during the process of ecological knowledge formation, those studies have become essential to the development of technologies and appropriate politics for the administration of the

11. Planejamento regional / territorial : a interface entre os planos diretores de aproveitamentos hidrelÃtricos e os planos diretores municipais
This research allowed to understand the way the Managing Plan of Hydroelectric Plants affects the organization of the territory. The use and occupation of the surrounding of the reservoirs of major hydroelectric enterprises have shown irregularities caused by the inappropiate use of these areas for tourism and recreation. Therefore, this work ananlyses the M

12. TÉCNICAS DE GEOPROCESSAMENTO NA DETERMINAÇÃO DO íNDICE DE PERIGO DE INCÊNDIOS / GEOPROCESSING TECHNIQUES TO DETERMINATE THE FIRE DANGEROUS LEVEL
The forest fire is considered an environmental impact, because provokes physic, biotic and anthropic environment characteristics changes or modifications. Brasil doesn t have an adequate fire politic support. It s necessary to obtain more precise information about the national territory, like the area size, existence of accesses ways and artificial lakes, la
