Consórcio intermunicipal para gestão ambiental nos municípios de pequeno porte 1 e 2 do nordeste paraense: uma possibilidade para gestão ambiental?
(Universidade Federal do Pará, 2014-09-30) MACEDO JUNIOR, Roberto Cavalleiro; VASCONCELLOS SOBRINHO, Mário; http://lattes.cnpq.br/7843288526039148
After being published the National Supplemental Law. no 140 (LC 140/2011) on 12/08/2011, which established the Jurisdictional power of the Towns in the administration regarding environmental policies, the importance to promote the enhancement of the environment setting up procedural requirements for all federal government agencies to prepare environmental impact assessments and environmental impact statements by implementing actions to guarantee the effectiveness of this law. However, the Municipal corporations needs the structure to expedite licenses and to supervise the activities that promotes or potentially degrade their areas. These policies would demand costly physical and personnel structure, being itself obstacles on its prioritization by the manager to proceed on the necessary law implementations. Thus, the cooperation between the federal members corporation through a Public Consortium instrument shows a strategic alternative to implement the law in small cities and submit their environmental issues. A regional territorial planning would be adequate referral to resource request as well as for the conclusion of contracts and agreements that benefits the cities which adhesion to the Public consortium would meet interests bringing inclusive more resources to accomplish this partnership. This study analyzes the Institutional Capacity of environmental management regarding Vigia de Nazaré, São Caetano de Odivelas, Santo Antônio do Tauá and Colares and intend a memorandum of understanding to formalize a public consortium for inter-municipal management of the environment. According to IBGE, these cities are small classes 1 and 2, located in Pará Northeast. During the search, after visiting the cities, it was noticed the lack of institutional capacity to promote environmental management in their own areas, such as lack of people, low personal training, shortage of financial resources, legislative omissions, inefficient councils and misusage of the cities funds and absence of rigging as cars and measuring equipment. Notwithstanding, they gathered tackling the situation with meetings to promote co-managements arrangements between cities managers to seek a joint solution to the problems of the region, given the territorial proximity and similarities of their natural resources. Being so, they ended up with a proposal for implementation of an inter-municipal consortium, through a cooperation agreement for full environmental management among the cities.

Distribuição e ecomorfologia de Neritina zebra (Bruguiere, 1792) (Mollusca: Gastropoda: Neritidae), em um estuário amazônico, Pará, Brasil
(Universidade Federal do Pará, 2012-05-25) CUNHA, Cristiane Vieira da; SANTOS, Franklin Noel dos; http://lattes.cnpq.br/2437036625902034; LEE, James Tony; http://lattes.cnpq.br/1693070833836566
The present study evaluates the vertical distribution of Neritina zebra in rocky outcrops in the lower and middle intertidal, intertidal as well as the horizontal distribution between rocky and clay substratas of an estuary in the Brazilian Amazon. The sampling areas are located in an oligohaline area in Icoaraci, Mosqueiro and Colares, at the coast of the State of Pará, Brasil. To evaluate the vertical distribution on orocky substrata, substratamolluscs were esampled in the lower and middle intertidal. intertidal In the lower mesolittoralmto, where clay and rocky substrata occur, substrataoccursamples were collected to verify the effect of the substrata on othe distribution of the mollusc.For each substrata and intertidal zonet zone, 22 replicates were randomly sampledusing a quadrant of 25x25cm² during the rainyrainy and dry season. An Analysis of Variance was seasonAAVancewasperformed to test (1) the effect of the intertidal zone and (2) the substrata onsubstratao the density of N. zebra. Analysis Athe vertical distribution results showed that in the lower zone, ,juvenile individuals show a higher density than in the middle zone, and an oppositeand anp pattern compared with adults appear to occur.Regarding the distribution on the different substrata,on the differentsubstrata results showed higher densities ono rocky substrate than onon clay substrata for young individuals, whereas no definite pattern was detected for adultss. This variability between the substrata and intertidal zones showed the influence of the seasons and the sampling sites. Icoaraci showed theshowedlowest densities, which can be associated to the anthropic activities in that area.

Pesca, policromatismo e aspectos sistemáticos de Potamotrygon scobina Garmam, 1913 (Chondrichthyes : Potamotrygonidae) da região da Ilha de Colares - Baía de Marajó - Pará
(Universidade Federal do Pará, 2003-03-07) ALMEIDA, Mauricio Pinto de; BARTHEM, Ronaldo Borges; http://lattes.cnpq.br/4192105831997326
The present study included specimens of the Family Potamotrygonidae, the only one among elasmobranchs formed entirely by freshwater representatives. This research was developed in the estuarine region of the Marajó Bay, in the island of Colares, during the months of May, August, October and December of 2000, December of 2001 and March of 2002. Sampling included the genera Plesiotrygon, Potamottygon, Paratrygon and a fourth undescribed genus, totalizing 723 captured specimens. Frequency of occurrence and biomass results indicated a predominance of the genus Potamotrygon especially of the species P. scobina in this area. Fishing gear utilized influenced the size of the stingrays captured. Specific observations related to the dorsal color patterns, size and sexual distribution of the species P. scobina were made. Results of multivariate statistical analysis and molecular genetics indicated that dorsal color patterns as currently employed in distinguishling morphotypes in fact did not indicate separate species and a single group was formed. Three previously undescribed dorsal color patterns for sub-adults / adults and two new patterns for juvenile specimens were identified for P. scobina. External characters analyzed for this species presented a wide variation in form, number, size and structure disposition that were more evident in sub-adults / adults. In this region, freshwater stingrays are routinely captured mainly for food and for medical and ornamental purposes. The conservation of freshwater stingrays species requires further knowledge about their biology and taxonomy in order to follow-up its exploitation and perhaps indicate management procedures.

Segurança alimentar em comunidades quilombolas: estudo comparativo de Santo Antonio (Concórdia do Pará) e Cacau (Colares, Pará)
(Universidade Federal do Pará, 2006-06-26) MENDES, Patrícia Miranda; ACEVEDO MARIN, Rosa Elizabeth; http://lattes.cnpq.br/0087693866786684
In this research the slight knowledge of alimentary security are presented, sovereignty and the dynamics of groups quilombolas through the analysis and quarrel of the alimentary diet and its transformations in the communities of the Cacau and Santo Antonio from the study of the ways of acquisition, social relations and its influence in the health of populations. The feeding system of the localities passes for a process of change occasioned, over all by the exhaustion of the nature resources associated with the population growth and the external pressure on the territories making it demands for more financial resources for its acquisition, what contributes in negative way in the diet, beyond causing changes in the alimentary habits. The feeding effect on social groups diet is demonstrated through a nutritional evaluation executed among the families members (adult, adolescent and children). Thus a comparison among the research results in the two communities is done so that the differences and the singularities in relation to the alimentary and nutricional security are observed.

Unidades de relevo em zona costeira estuarina: municípios de Colares e Santo Antônio do Tauá
(Universidade Federal do Pará, 2007-08-20) BARBOSA, Estêvão José da Silva; FRANÇA, Carmena Ferreira de; http://lattes.cnpq.br/5723672412810714
This work identified and argued the geomorphic units (relief) of Colares and Santo Antônio do Tauá municipalities, State of Pará, Brazil. It has Geomorphology as subject. The studied area is located in eastern portion of Amazon River Estuary (“Golfão Marajoara”), northeast of Marajó bay, at estuarine coastal zone. In this study was used: bibliography, maps, remote sensing data and work fields. The analysis was made by two scales. First Scale is represented by the Amazonian Coastal Zone, which shows low altitude, sedimentary lithology, macrotidal tidal range, tropical and wet climate and stronger river discharges. This regional coast was produced by relative sea-level fluctuations, climatic changes, and tectonic dynamics occurred throughout Late Cenozoic. Eastern portion of Amazon River estuary is formed by Pará River Estuary – Marajó Bay, a typical tidal river or river-dominated estuary, although it has tidal influence. River discharge is main component of the estuarine dynamics, sedimentary constitution and biota organization. Pará River Estuary is a coastal environment with less energy of waves and littoral currents than the shore of Northeast Pará. In the second scale, were identified eight geomorphic units: sandy estuarine channel; tidal mud bank; tidal mud flat; estuarine beach; dune-beach ridge; tidal influence alluvial plain; alluvial plain; plateau. Only plateau is a erosive relief unit. The research also deals spatial distribution of these geomorphic units, in two sectors. Sector 1 is located in western portion of studied area. It is largely influenced by tides, and has different depositional relief units. The major geomorphic unit is tidal influence alluvial plain, which results of transition between marine and alluvial factors. Freshweater swampy formations followed mangroves toward landward due to reduced saline influence in the channels. Sedimentary distribution is marked by sand bottom channels, and mud deposits in the margins. Beachs are shorts, commonly covered by mud sets because less wave energy and crucial role of tidal current, discharges action in the coastal dynamics. Dune-beach ridges localized landward coastal plain are the indicative its progression. In this sector, plateaus are discontinuous due to erosion and deposition by tidal, flow channels and rains. Sector 2, localized in eastern portion of studied area, has no tidal influence. It shows a relief little compartmented, with large plateaus dissected by rivers. Fluvial action formed valleys with narrow alluvial plains, which demonstrated a greatest erosive surface in the sector 2.
