1. Water pollution: one of the main Limnology challenges in the Anthropocene
Resumo: A humanidade está definindo um novo período geológico. A era do Antropoceno é marcada por mudanças nos processos geológicos, nos regimes hidrológicos, na estrutura da biosfera, dentre outros processos devido às expansões humanas sobre a paisagem ao redor do mundo. A aceleração dos ciclos biogeoquímicos, a grande carga de poluentes nos rec

3. Phosphorus Forms in Sediments as Indicators of Anthropic Pressures in an Agricultural Catchment in Southern Brazil
ABSTRACT Phosphorus (P) fractionation is a suitable procedure to ascertain P lability in sediments and is able to distinguish sources of P under different soil management practices in a catchment. Brazil is the second largest producer and the largest exporter of tobacco in the world. Inadequate management of cultivated areas exposes the soil to erosion proce

4. Comparative metagenome of a stream impacted by the urbanization phenomenon
Abstract Rivers and streams are important reservoirs of freshwater for human consumption. These ecosystems are threatened by increasing urbanization, because raw sewage discharged into them alters their nutrient content and may affect the composition of their microbial community. In the present study, we investigate the taxonomic and functional profile of th

5. AVALIAÇÃO DA EFICIÊNCIA DO MÉTODO TO-15 PARA DETERMINAÇÃO DE COMPOSTOS ORGÂNICOS VOLÁTEIS EM CONDIÇÕES TÍPICAS DE AMBIENTE URBANO
The efficiency of U.S.EPA TO-15 Method was evaluated under typical conditions of an urban environment with natural and anthropic emission sources. The performance criteria which should be met for a system to qualify, were fulfilled: a detection limit of ≤0.2 ng for all target compounds, replicate precision for a calibration standard and ambient samples wit

6. Population biology of the ‘uçá'-crab, Ucides cordatus(Linnaeus, 1763) (Brachyura: Ucididae), in mangroves of the Joanes River, Bahia State, Brazil
ABSTRACTThis study evaluated the population structure, relative growth and morphological maturity size in Ucides cordatus in the Joanes River, Bahia State (Brazil). Crabs were sampled in a fragmented and human-altered mangrove ecosystem in a Brazilian Environmental Protected Area (EPA). A total of 431 crabs were sampled (265 males and 166 females) between Se

7. Genética aplicada à ecologia de estradas: um estudo na estrada municipal Guilherme Scatena (São Carlos, SP) e potencial impacto na biodiversidade local.
Roads generate a large ecological impact to wildlife by raising barriers among ranges of species originally continuous and for causing road-kills. After road-killing, a morphological identification becomes impossible for the loss of diagnostic features, especially in the case of small vertebrates. Use of molecular tools for identification is an alternative t

8. Interações tróficas de peixes marinhos no Estado de São Paulo: banco de dados e comparações espaço-temporais / Trophic interactions of marine fish in the State of São Paulo: database and spatial-temporal comparisons
The marine ecosystems of São Paulo State are under intense anthropic pressure. Considering that trophic studies of fishes are essential to the management of ecosystems and fisheries, a fish stomach content database was built in order to summarize the available data in the region. Primary (unpublished) and secondary (published) data were inserted, representi

9. Zooplankton of an urban coastal lagoon: composition and association with environmental factors and summer fish kill
Zooplankton may be regarded as a sensitive tool for monitoring environmental variations in coastal lagoons due to their ability to immediately react to changes in the water column trophic features and salinity levels. As a coastal lagoon with a broad history of anthropic influence, Rodrigo de Freitas Lagoon (Rio de Janeiro, Brazil) is widely used for water s

10. Estudo de dinâmicas de paisagens no baixo curso do Rio Ipojuca, Pernambuco: potencial para sustentabilidade socioeconômica e cultural da região / Study of landscape dynamics in the lower course of Ipojuca river, Pernambuco: potential for the socioeconomic and cultural sustainability of the region
One of the greatest challenges in environmental planning and management is related to the need of overcoming the different regionalization forms. Since the beginnings, several are the unifying the basis efforts which allow a conciliatory limits management and space interventions. This project aims to analyze the landscape dynamics of the lower course of Ipoj

11. Molecular investigation of Rickettsia in arthropods vectors in area under accentuated anthropic pressure in the Rio Doce Valley, State of Minas Gerais / Infecção por Rickettsia em artrópodes vetores de uma região sob acentuada pressão antrópica no Vale do Rio Doce, Estado de Minas Gerais
O gênero Rickettsia é constituído por alfa-proto-bactérias gram-negativas, pleomórficas, parasitas intracelulares obrigatórias que infectam preferencialmente células endoteliais, podendo ser transmitidas ao hospedeiro vertebrado por meio de pulgas, piolhos e, principalmente, carrapatos. Esses microrganismos, amplamente distribuídos pelo mundo, são r
