Aedes aegypti is almost completely restricted to human-modified environments, especially urban areas, and rarely invades forests. Ovitraps were utilized in a reserve (Bom Retiro) in Rio de Janeiro state. Eggs of A. aegypti, genetically not differentiable from those of urban mosquitoes, were obtained at a location more than 700 m inside the border of the forest and 900 m away from a trail at the entrance to the forest. The presence of A. aegypti in a primary forest indicates its ability to adapt to sylvatic environments in Brazil, suggesting great potential for the transmission of several arboviruses due to the difficulty in controlling these mosquitoes.

A presença de Aedes albopictus (Skuse) em área urbana representa um risco potencial do inter-relacionamento dessa espécie de mosquito com a população. Este estudo teve como objetivo identificar as formas imaturas de Ae. albopictus encontradas nos depósitos e imóveis do município de Miguel Pereira. O estudo foi realizado no período de 12 meses, ano de 2007, em 27 locais do município de Miguel Pereira, Estado do Rio de Janeiro. As larvas encontradas foram identificadas em laboratório e a análise dos dados foi calculada pelos índices de infestação predial e índice de Breteau. Os tipos de imóveis positivos foram residências (79,44% do total); terrenos baldios (2,56%); comércios (2,56%) e outros tipos de imóveis (15,04%) para Ae. albopictus, e residências (72,72% do total); comércios (6,06%); terrenos baldios (3,03%); e outros tipos de imóveis (18,18%) para Aedes aegypti (L.). Das 3731 larvas, 3562 (95,5%) eram de Ae. albopictus e 169 (4,5%) de Ae. aegypti. O mosquito Ae. albopictus mostrou-se mais presente nos criadouros que Ae. aegypti. A média do índice de infestação predial (IFP) e índice de Breteau (IB) para Ae. albopictus foi 1,0 e 1,9 e para Ae. aegypti de 0,1 e 0,1, respectivamente. As formas imaturas mais abundantemente encontradas no Município de Miguel Pereira no ano de 2007 foram de Ae. albopictus podendo futuramente se tornar um problema de saúde pública. Incidence of Aedes albopictus (Skuse) Immature Form in Miguel Pereira, RJ, Brazil. Abstract. The presence of Aedes albopictus (Skuse) in urban areas represents a potential risk of inter-relationship of this species of mosquito with the population. This study aimed to evaluate the presence of the Ae. albopictus immature forms in deposits and building at Miguel Pereira city, Rio de Janeiro State. The study was carried in the last 12 months, 2007, in 27 locations in Miguel Pereira city. The larvae were identified in laboratory and data analysis was calculated by indicators of building infestation index and the Breteau index. The positive buildings were: residential (79.44% of total); waste land (2.56%), shopping (2.56%) and other types of buildings (15.04%) to Ae. albopictus, and homes (72.72% of total), shopping (6.06%); waste land (3.03%) and other types of buildings (18.18%) to Ae. aegypti (L.). The larvae (3731) collected, 3562 (95.5%) were Ae. albopictus and 169 (4.5%) were Ae. aegypti. The Ae. albopictus are more present in breeding that Ae. aegypti. The average rate of building infestation index (IFP) and Breteau index (IB) for Ae. albopictus was 1.0 and 1.9 and for Ae. aegypti was 0.1 and 0.1, respectively. The Ae. albopictus immature larvae forms were more abundantly found in the Miguel Pereira city in 2007; in future it may become a public health problem.

Due to the small number of records of Streblidae on bats, despite extensive study on these mammals in the state of Rio de Janeiro, a survey was carried out in an area of the Atlantic Forest. The present study was carried out at Bom Retiro Farm Natural Heritage Private Reserve. We captured 401 bats of 17 species, 13 genera, and four families; bat flies infested 221 bats of only four species. Carollia perspicillata (Linnaeus, 1758) has the highest fly diversity, with seven fly species: Trichobius joblingi (Wenzel, 1966) (n = 23), Megistopoda proxima (Séguy, 1926) (n = 15), Strebla guajiro (García & Casal, 1965) (n = 15), Aspidoptera falcata (Wenzel, 1976) (n = 6) Paratrichobius longicrus (Miranda Ribeiro, 1907) (n = 8), Paraeuctenodes similis (Wenzel 1976) (n = 3), and Trichobius anducei (Guerrero, 1998) (n = 1). Two species infested Platyrrhinus lineatus (É. Geoffroy, 1810): Aspidoptera falcata (n = 1) and Anastrebla caudiferae (Wenzel, 1996) (n = 1). Paradyschiria parvula (Falcoz, 1931) (n = 11) infested Noctilio leporinus (Linnaeus, 1758) and M. proxima (n = 12) and Trichobius uniformis (Curran, 1935) (n = 1) infested Sturnira lilium (É. Geoffroy, 1842). Sturnira lilium has the highest infestation rate, with ten out of 46 captured individuals parasitized, followed by Carollia perspicillata, with 33 out of 164 captured parasitized, and by P. lineatus with only two parasitized individuals out of ten. Among 97 streblid flies captured, M. proxima was the most abundant (27.83%), followed by T. joblingi (23.71%), and S. guajiro (15.46%). All remaining bat fly species represented 33%. Paradichyria parvula has the first record for Rio de Janeiro State.

The Atlantic Forest in the state of Rio de Janeiro is extremely fragmented and reduced in its original extension. Although there are a great number of studies related to the biome, few lists are available for this region. The present study seeks to get information on the mammals of a remnant forest in Serra da Concórdia, an area from which no information is currently available. The rapid mammal's survey was accomplished by use of pitfalls, live traps, transects, mist nets, and camera traps. We recorded 37 terrestrial species that represent 22.3 % of Rio de Janeiro state mammal species. Among the recorded species, six are endemic of the Atlantic Forest, one is endemic of the state, and eight are in the state list of threatened or presumably threatened species. The area presents great mammal richness and an increasing effort will probably reveal the presence of additional species.

Medium and large-sized terrestrial mammals develop important functions in ecosystems maintenance. However, this group is the most vulnerable to local extinctions, through habitat loss or hunting. This study inventoried the community of medium and large mammals in the Reserva Ecológica de Guapiaçú (REGUA), Cachoeiras de Macacu, RJ, providing data on species composition, richness and abundance. Species were registered through the use of camera traps, sign survey and visual encounters on pre-existing trails and roads. The study was conducted from January to October 2012, with each month considered as a sample unit. An effort of 1568 cameras-day and 120 km traveled, resulted on 302 records of 22 species of medium and large-sized mammals, belonging to eight orders. This value corresponds to more than three-quarters of the richness described from this group in the Atlantic Forest of Rio de Janeiro state. Five species are under some level of regional, national or global threat. Three game species, Pecari tajacu, Cuniculus paca and Dasyprocta leporina were abundant in the area. The observed richness was comparable to that found in other studies conducted in rain forests. Thus, for its high number of species, including those under some degree of threat, we conclude that REGUA is an important area to mammal conservation, especially in the Atlantic Forest of Rio de Janeiro state.

We present the first record of the Dipsadidae snakes Xenopholis scalaris for the state of Rio de Janeiro and a general distribution map for this species. This record for the Brazilian Atlantic Forest expands the known geographical distribution of X. scalaris and reveals that its populations might not be isolated or disjunctive, but rather rare in this biome. We also provide some recommendations for future conservation of X. scalaris.

A disposição inadequada dos resíduos sólidos, atualmente, constitui um problema para a sociedade, tendo em vista os impactos ambientais que provoca, alterando a qualidade do solo, do ar e dos corpos aquáticos, e representando um risco para a saúde pública. Este artigo aborda aspectos do gerenciamento de resíduos sólidos na região Metropolitana II do Estado do Rio de Janeiro, discutindo ações desenvolvidas nesta área, da coleta à destinação final. Mais especificamente, analisa aspectos relacionados às classes de resíduos, resíduos sólidos gerados e triados, à situação atual da destinação final e ao gerenciamento de resíduos hospitalares, traçando-se, ao final, um panorama da situação do gerenciamento dos resíduos sólidos local. Durante os meses de janeiro a junho de 2008, foram realizadas visitas aos locais de destinação final dos resíduos sólidos - os aterros controlados e lixão, bem como entrevistas com técnicos responsáveis pelas ações de gerenciamento dos resíduos sólidos das Secretarias Municipais do Meio Ambiente, de Obras e de vigilância ambiental em saúde das Secretarias de Saúde, dos municípios da Região Metropolitana II, a saber: Niterói, São Gonçalo, Itaboraí, Maricá, Tanguá, Rio Bonito e Silva Jardim. A região Metropolitana II do Estado do Rio de Janeiro, embora composta por municípios com realidades bastante diferenciadas em termos de desenvolvimento social e econômico, possui grande parcela da população vivendo em condições precárias e sem acesso aos serviços públicos de saneamento, saúde e educação, vulnerável aos impactos ambientais. Verifica-se que a disposição final com o tratamento adequado dos resíduos sólidos constitui importante problema, não só para os governos e políticas públicas locais, mas também para as populações que convivem com os lixões. Destaca-se o importante papel dos catadores informais pelas cidades, muitos se organizando em pequenas cooperativas e grande parte operando em áreas urbanas onde o lixo é armazenado, aguardando coleta pública, ou, ainda, em alguns dos aterros controlados e no lixão da região. Há urgência de implantação de aterros sanitários ou aterro consorciado, desativando-se as áreas atuais de lixões e/ou aterros controlados, com ações de remediação de áreas degradadas, e, enfim, que se adotem soluções que dêem conta dessa importante parcela do saneamento básico, minimizando o impacto negativo dos solos e águas subterrâneas contaminados, visando-se a sustentabilidade da saúde e do ambiente, e o bem-estar das pessoas. Palavras-chave: Resíduos sólidos, Gerenciamento de resíduos sólidos Abstract The inadequate disposal of the solid residues, nowadays, is a social problem, concerning to suffered environmental impact, changing the quality of the soil, the air and of the water, being a risk to the public health. This article is about aspects of solid residues management at Metropolitana II region of the Rio de Janeiro state, discussing the development of actions on this area, from the collect to the final destination. More specifically, we analyze aspects related to the classes of residues, solid residues that were generated and discriminated, the actual situation of the final destination and to the management of the hospitals residues, constructing, at the end, a view of the local management of the solid residues. From January to June of 2008, visits were made at the locals of the final destination of the solid residues – the controlled landfills and the disposal waste areas, as well interviews with responsible technicians about actions of solid residues management of the environmental municipal secretaries, of Metropolitana II region: Niterói, São Gonçalo, Itaboraí, Maricá, Tanguá, Rio Bonito e Silva Jardim. The Metropolitana II region of the Rio de Janeiro state, although composed of very different realities between the municipals, concerning to economic and social development, has great portion of the population living in precarious conditions and without access to sanitary public services, health and education, vulnerable to the environmental impacts. We verify that the final disposal with adequate treatment of the solid residues constitute import problem, not only to the government and local public policies, but also to the population that live within waste. We mark the important function of the informal garbage pickers in the cities, many of them organized in small co-operative societies and a great part acting in urban areas where the trash is stored, waiting public collecting, or at some controlled landfill and disposal waste area. It's urgent the implementation of the sanitary landfills or partnership landfills, discarding the actual areas of waste disposal and/or controlled landfill, with remediation actions on the deteriorate areas, and, finally, solutions must be adopted to solve this important portion of the basic sanitation, minimizing the negative impact of the soil and contaminated subterranean water, aiming the health and the environmental support, and the well being of people.
