Fatores influenciadores da participação pública na tomada de decisão ambiental :o caso do programa de combate ao caramujo gigante (Achatina fulica) em Parnamirim/RN

The aim of this work is to investigate the factors which influence people s participation in the enviromental decision, in Parnamirim, Rio Grande do Norte, from the vision of the residents of that area, approaching the Plan of Control/Eradication of the African s Huge Snail (Achatina Fulica),with the jointly work of IBAMA and Municipal Town Hall of Parnamirim .The applied methodology consists of a research (Survey kind) including 395 interviews by people who live in that county, with minimum age of 18, within an universe of 124.690 residents. The choice of the county was due to a detection (made by IBAMA technicians and reported in a Technical Report) -which showed that the dangerous Snail is already spreading in 14 of 17 districts of the county-, as well as the support given by Parnamirim s Town Hall, with the implementation of the Plan Control/Eradication of the African s Huge Snail, widely known as Day C . The research tools used in that research consists of questionnaires with all sorts of questions. The results show us that most of the residents were feeling threatened by the presence of the animal as well as having had a little participation in the fight against the animal. It also shows us that residents believe that organizations (Town Hall, IBAMA and Local Community) involved are able to solve the problem and believe that the amounts which organization are supposed to take 89,4 %, 87,6% and 80,8%, in that order. As we check the results, we notice in 95%, the variety of threaten and frequency reunion and participation level

Built to Bite: Feeding Kinematics, Bite Forces, and Head Shape of a Specialized Durophagous Lizard, Dracaena Guianensis (Teiidae)

Most lizards feed on a variety of food items that may differ dramatically in their physical and behavioral characteristics. Several lizard families are known to feed upon hard-shelled prey (durophagy). Yet, specializations toward true molluscivory have been documented for only a few species. As snails are hard and brittle food items, it has been suggested that a specialized cranial morphology, high bite forces, and an adapted feeding strategy are important for such lizards. Here we compare head and skull morphology, bite forces, and feeding kinematics of a snail-crushing teiid lizard (Dracaena guianensis) with those in a closely related omnivorous species (Tupinambis merianae). Our data show that juvenile D. guianensis differ from T. merianae in having bigger heads and greater bite forces. Adults, however, do not differ in bite force. A comparison of feeding kinematics in adult Dracaena and Tupinambis revealed that Dracaena typically use more transport cycles, yet are more agile in manipulating snails. During transport, the tongue plays an important role in manipulating and expelling shell fragments before swallowing. Although Dracaena is slow, these animals are very effective in crushing and processing hard-shelled prey. J. Exp. Zool. 317A:371381, 2012. (c) 2012 Wiley Periodicals, Inc.

Toxicidade aguda do sulfato de cobre e do extrato aquoso de folhas secas de nim para o caramujo (Pomacea canaliculata)

Snails can become an environmental and economic problem, causing substantial losses. The objective of this work was to estimate the acute toxicity of copper sulfate pentahydrate (CuSO4.5H2O) and the aqueous extract of dried neem leaves on snails (P. canaliculata) under laboratory conditions. In order to estimate the lethal concentration 50% (LC (I)50;96h), snails were exposed to six increasing copper sulfate concentrations (0.0; 0.01; 0.03; 0.05; 0.07 and 0.1 mg L-1) and six increasing concentrations of aqueous extract of dried neem leaves 0.0; 100; 125; 150; 175 and 200 mL aqueous extract of dried neem leaves L-1 water, equivalent to (0.0; 1.18; 1.47; 1.77; 2.06 and 2.36 mg azadirachtin L -1), in triplicate and one control treatment in an entirely random delineation. Estimated LC (I)50;96h, of copper sulfate was 0.02 mg copper sulfate L-1, with a 0.01 mg L-1 lower limit and a 0.03 mg L-1 upper limit. Estimated lethal concentration 50% of the aqueous extract of dried neem leaves was 142.75 mL L-1, equivalent to 1.68 mg L-1 of azadirachtine, with a 130.89 mL L-1 (1.54 mg L-1) low limit and 155.69 mL L-1 (1.83 mg L -1) as the upper limit.

Dilemas do planejamento e da gestão municipal na Amazônia ribeirinha: uma análise do caso de Cametá à luz do ideário da reforma urbana e do Estatuto da Cidade

Trata a presente pesquisa de um estudo que discute os instrumentos de reforma urbana concebidos no Estatuto da Cidade relacionados às especificidades sócio-espaciais de um município ribeirinho amazônico. Busca-se identificar e analisar o ideário de reforma urbana proposto pelo Movimento Nacional pela Reforma Urbana (MNRU) e concebido no Estatuto da Cidade atentando para as especificidades sócio-espaciais do Município de Cametá, Estado do Pará. Para a realização da pesquisa recorreu-se a uma abordagem histórico-dialética sobre a problemática enfocada e se utilizou, como procedimentos de pesquisa o levantamento e a análise bibliográfica e documental (Estatuto da Cidade e Plano diretor de Cametá); aplicação de entrevistas semi-estruturadas junto à equipe elaboradora do plano diretor municipal, junto aos integrantes de movimentos sociais urbanos e rurais e junto ao poder público. Por meio da análise, concluiu-se que municípios ribeirinhos como Cametá, em virtude de apresentarem especificidades sócio-espaciais no contexto amazônico e brasileiro, enfrentam dilemas relacionados ao planejamento e à gestão urbana e municipal, distanciando-se, algumas vezes, das diretrizes e princípios estabelecidos genericamente para o território nacional. Tal questão revela a importância de pensar a diversidade sócio-espacial brasileira e amazônica, bem como a necessidade de viabilizar adequações de instrumentos e preceitos que buscam nortear as diversas práticas de planejamento e de gestão em nível local, não obstante os avanços relacionados a essas mesmas práticas nos últimos anos no Brasil.

Mobilidade de camponeses entre assentamentos de reforma agrária: territorialidades em cheque no desenvolvimento local da Transamazônica, Pará, Brasil

O artigo trata do papel da mobilidade espacial de famílias camponesas entre assentamentos da chamada reforma agrária no desenvolvimento local da região Transamazônica, Estado do Pará. A análise das práticas e narrativas de sujeitos locais no contexto de políticas públicas fundiárias e ambientais evidencia que essa execução vigente não se coaduna com os processos de territorialização concebidos pelos chamados beneficiários de reforma agrária.

Bioindicadores neotropicais de ecotoxicidade e risco ambiental de fármacos de interesse para aquicultura

The aims of this research were to evaluate the acute toxicity (LC/EC50) and the environmental risk of toltrazuril (TOL) and florfenicol (FFC) for plant Lemna minor, snail Pomacea canalicuta, fish Piaractus mesopotamicus and Hyphessobrycon eques and the microcrustacean Daphnia magna. The organisms were acclimated in room bioassay with controlled temperature according to standard to each one. They were exposed at nominal concentrations in static system. For environmental risk (RQ) was used the estimated environmental concentration (EEC) that is the dosage indicate to treatment and the lethal or effective concentration (LC/CE50) from each drug in acute exposure. FFC showed LC50;7d of 97.03 mg L-1 for L. minor; >100.0 mg L-1 for P. mesopotamicus and H. eques and EC50;48h > 100.0 mg L-1 for P. canaliculata and D. magna, and it was classified low risk (RQ = 0.01) for all bioindicators. TOL howed LC50;7d >100.0 mg L-1 for L. minor, 3.72 mg L-1 for P. mesopotamicus; 6.22 mg L-1 for H. eques and CE50;48h of 7.59 mg L-1 for P. canaliculata and 18.57 mg L-1 for D. magna, and it was classified low risk (RQ = 0.01) for L. minor and high risk for P. mesopotamicus (RQ = 2.68), H. eques (RQ = 6.22), P. canaliculata (RQ = 1.31) and D. magna (RQ = 0.53). Lemna minor was the bioindicator indicating of FFC toxicity and H. eques, bioindicator of the TOL. FFC is safety however and the use of TOL necessaries cautions to treat the wastewater before discard on the environment.
