O amálgama floresta e agricultura na Reserva Extrativista Arióca Pruanã
(2013-06) SILVA JUNIOR, Amintas Lopes da; SANTOS, Sônia Maria Simões Barbosa Magalhães; SABLAYROLLES, Maria das Graças Pires
The present study addresses the role of orchards and yards as interface between agriculture and extractivism in the Arióca Pruanã Extractivist Reserve, in the city of Oeiras, Pará state, Brazil. The agriculture depends on the forest and reconfigures it into secondary forests and orchards, as well as the forest insinuates itself into the yards as the wild plant species are therein introduced by human hands. The result of this management is the agroforestry in the landscape, visible face of the amalgam between agriculture and forest, and reproduction basis of the riparian lifestyle.

Campesinato, identidade e memória: os tiradores de açaí ou como colocar-se no mundo
(2014-06) SALES, Sammy Silva; PORRO, Noemi Sakiara Miyasaka
This paper aims think the relation between peasantry and identity concepts as from the case study of tiradores de açaí, called Monteiro family, villagers Monteiro, located in Afuá, state of Pará. The field datas were collected through participant observation and interview in 2011 and 2012. We argue that the tiradores de açaí, in situations of reflection on the present, and through their practices, by social representations and collective memory building their social identities with social processes in which they are inserted.

Ciência, cientistas e democracia desfigurada: o caso Belo Monte
(2011-06) MORAL HERNÁNDEZ, Francisco del; MAGALHÃES, Sônia Barbosa
The hydroelectric frontier in the Amazon is expanding due to the construction of large projects such as Santo Antonio and Jirau in the Madeira River, proposed projects in the Tapajós River, and Belo Monte in the big bend of the Xingu River (licensed in February 2010). Large projects that generate energy in the Amazon region provoke political, social, and environmental confl icts. These confl icts affect the credibility of the Environmental Licensing Evaluation process. Discourse from social groups that oppose development policies for the Belo Monte Hydroelectric Dam project offer insight into the origins and progression of these confl icts. Criticisms of the Experts Panel Network created to analyze the Environmental Impact Assessment in Belo Monte and other sectors of the society are evaluated.

Diversificação dos sistemas produtivos familiares: reflexões sobre as relações sociedade-natureza na Amazônia Oriental
(2011-12) OLIVEIRA, Myriam Cyntia Cesar de; ALMEIDA, Jalcione; SILVA, Luis Mauro Santos
This article weaves some reflections on the relations society-nature in the Amazon region from the changes for the diversification that is taking place in the south-east from Pará. Leaving from a glance on the ways of the agriculture, it was tried to situate like the types of relations with nature they infl uenced the forms of exploration adopted in the region and what these changes mean in terms of the relations between farmers and the natural environment. The text discusses the principal elements and motivations that are in the constitution of this process of diversification, establishing a relation of the same thing with the capacity of adaptation and with the change of projects of the farmers in the sense of the permanence. In this sense, it seems to this change to illustrate the existence of the same process of relative stabilization of the farmers, already identified in other frontiers.

Does body size of neotropical ant species influence their recruitment speed?
(2013-03) GODOY, Bruno Spacek; CAMARGOS, Lucas Marques de
Ants are one of the most important animal groups in tropical forests because of its abundance and number of species. An important characteristic of the group is the eusociality, which allows the occurrence of a recruitment behavior when food resource is found. However, there are two main questions regarding this behavior: (i) the recruitment is a product of environmental or phylogenetic pressures, and (ii) the recruitment speed is related to the body size of the ant species. In this work we addressed these two questions using 17 species of neotropical ants, in the Amazonic lowland dense rain forest. According to results, recruitment behavior is related to ant size, where smaller species exhibit this trait when finding a protein resource. However, species size is not important in recruitment speed, which suggests that speed can be best explained by the type of food resources needed in the ant colony.

Estimação de parâmetros genéticos para características produtivas em búfalos na Amazônia Oriental
(2010-06) RODRIGUES, Alessandra Epifanio; MARQUES, José Ribamar Felipe; ARAÚJO, Cláudio Vieira de; CAMARGO JÚNIOR, Raimundo Nonato Colares; DIAS, Lilian de Nazaré Santos
Data from 1,182 records of Murrah females buffaloes and their crossbreds, calving from 1967 to 2005, were used to estimate genetic parameters by maximum restricted likelihood method. An animal model used to estimate variance components, included the fixed effects of herds, year and season of calving, order of parity, and length of lactation as covariables; and random effects of animal, permanent, and temporary environment. The estimate of heritability to milk yield, fat yield, length of lactation, and milk yield per day of calving interval were 0.25, 0.18, 0.08, and 0.09 respectively. Estimate of repeatability for milk yield, fat yield, and length of lactation were 0.33, 0.29, and 0.10, respectively. The genetic correlations between milk yield and fat yield, milk yield and length of lactation, milk yield and milk yield per day of calving interval, fat yield and length of lactation, fat yield and milk yield per day of calving interval, and length of lactation and milk yield per day of calving interval were 0.93, 0.76, 0.99, 0.89, 0.87, and -0.27, respectively. These results showed that genetic gains may be obtained by selecting to milk and fat yields.

Hermenêutica botânica e antropização na Amazônia: exsicatas de verbenáceas da Amazônia Legal no Herbário do New York Botanical Garden
(2011-12) GUERRA, Gutemberg Armando Diniz; MENEZES, Maria de Nazaré Angelo; MING, Lin Chau
This article is based on information from a historical series of dried herbarium specimens dating from 1819 to 2002, bringing together contributions from researchers in both governmental and nongovernmental organizations from North and South America as well as from Europe. The focus is on Verbenaceae by its recognized range of aromatic and medicinal species of this family and its recognized use in Brazil. The study examines descriptive and critical notes from the New York Botanical Garden collection relating to the Amazonia, revealing the spirit of cooperation between Brazilian and foreign institutions in this region. Changes in the environment, network of researchers, changes in the language system, technology records and absorption of regional terms are detected over almost two centuries of scientific work that projects the continued training of scientists with local knowledge and interaction.

Mobilidade de camponeses entre assentamentos de reforma agrária: territorialidades em cheque no desenvolvimento local da Transamazônica, Pará, Brasil
(2015-06) SANTOS, Ione Vieira dos; PORRO, Noemi Sakiara Miyasaka; PORRO, Roberto
The article discusses the role of turnover of peasant families at agrarian reform settlements for the local development of the Transamazon region in the State of Pará. Analysis of local practices and narratives in the context of land and environmental policies evidences that their current implementation is not consistent with processes of territorialization designed by so-called beneficiaries of land reform.

Ocorrência da leucose enzoótica dos bovinos no Estado do Pará, Brasil
(1999-01) MOLNÁR, Lászlóné Éva; MOLNÁR, László; DIAS, Hilma Lúcia Tavares; SILVA, Aluizio Otavio Almeida da; VALE, William Gomes
The occurrence of the infection with Bovine Leukosis Virus (BLV) was examined in agar-gel immunodiffusion (AGID) test and with indirect enzyme-linked immunosorbent assay (ELISA), in the State of Pará, Brazil. The blood sera were collected from different breeds including Nelore, Piemontes, Simental, Holstein Frisian, Indubrasil, Girolanda, Simbrasil and their cross-breedings. The majority of the animals were adults. The overall occurrence of infections was 49.8% (359/721) and 26.0% (174/668) for ELISA and AGID test, respectively. All animal groups examined showed infection in ELISA, however in the AGID test two groups were sera negative.

Processos de ocupação nas novas fronteiras da Amazônia: o interflúvio do Xingu/ Iriri
(2005-08) ESCADA, Maria Isabel Sobral; VIEIRA, Ima Célia Guimarães; KAMPEL, Silvana Amaral; SANTOS, Roberto Araújo de Oliveira; VEIGA, Jonas Bastos da; AGUIAR, Ana Paula Dutra; VEIGA JUNIOR, Iran Pereira; OLIVEIRA, Myriam Cyntia Cesar de; PEREIRA, Jorge Luís Gavina; CARNEIRO FILHO, Arnaldo; FEARNSIDE, Philip Martin; VENTURIERI, Adriano; CARRIELLO, Felix; THALÊS, Marcelo Cordeiro; CARNEIRO, Tiago Garcia de Senna; MONTEIRO, Antônio Miguel Vieira; CÂMARA, Gilberto
This work presents the first results achieved through an interdisciplinary and multi-institutional effort conduct by the Geoma Network, aiming to advance in the comprehension of the new frontiers in the South of the Pará State, in the Amazonian region, by examining the new patterns of deforestation and the underlying processes that are generating them. Our objective is to product information aiding to draw responsible public policies considering not only one dimension of the problem like roads infra-structure, as usual. Based on the analysis presented here we pointed out that only an integrated solution, that considers the main actors and the organization of economical processes in the productive chains over the region, would be capable to minimize the effects of deforestation and would drive an integrated development policy to the region bringing benefits to forest conservation and the local population.

Trabalho familiar ou assalariamento? Dilema de jovens em comunidades rurais
(2013-06) ALVES, Ketiane dos Santos; MOTA, Dalva Maria da
The objective of this work was to analyze working strategies used by young people in the agricultural production with strong natural limitations in northeastern Pará. A case study was carried out in 2010 in the community of Nossa Senhora de Lourdes, in the municipality of Mãe do Rio. The main results show that the slash-and-burn based model of natural exploitation in areas of 25ha has caused great problems associated with the depletion of natural resources. Thus, the work strategies, especially among the young people are being rearranged. They now seek wage-earning activities as an alternative to obtain incomes faster and to develop their autonomy projects. This new reality has promoted changes in manpower demand and hiring in their units of origin and an overload of work for the people who remain in the family work.
