Abundância, composição e diversidade de Arctiinae (Lepidoptera, Arctiidae) em um fragmento de floresta na Amazônia Oriental em Altamira, PA, Brasil
(Instituto Nacional de Pesquisas da Amazônia, 2012-03) TESTON, José Augusto; NOVAES, Jessé Bucioli; ALMEIDA JÚNIOR, José Otávio Barros
This study evaluated the Arctiinae fauna in a fragment of primary forest in Altamira, Pará, Eastern Amazonia, Brazil. The moths were sampled during two years (from August 2007 to July 2009) with a light trap. The following parameters were measured: richness, abundance, constancy, diversity and evenness indices (Shannon H ‘and E') and Brillouin (H and E), and dominance index of Berger-Parker (BP). The richness estimatives were made by nonparametric procedures, Bootstrap, Chao 1, Chao 2, Jackknife 1, Jackknife2 and Michaelis-Mentem. Four hundred and sixty-six individuals of 78 species of Arctiinae were captured, of which twelve are new records for Pará State. Values of parameters analyzed for the entire period were: H ‘= 3.08, E' = 0.708, H = 2.86, E = 0.705, and Sp = 0.294. Communities of the less rainy months were more diverse. Estimators predicted an increase between 17 to 253 in species richness.

Agricultura urbana: contribuição e importância dos quintais para a alimentação e renda dos agricultores urbanos de Santarém - Pará
(Universidade Federal do Pará, 2011-08-29) SILVA, Eliane Raíssa Ribeiro; SABLAYROLLES, Maria das Graças Pires; http://lattes.cnpq.br/0250972497887101
The formation of urban neighborhoods in the area of Santarem is based on agricultural production, and this determines the socio-territorial reorganization of the city, causing it to present contradictions, and despite being "inside" of what is considered urban, are visible in this area habits and customs remain rural and agricultural production discussed here as urban agriculture. To identify and characterize the different activities of urban agriculture observed in Santarém / Pará (2 ° 24 '52 "S and 54 º 42' 36" W), to assess the importance and contribution of the same for food and income for families of farmers to develop, this study was conducted. Data collection was through home visits to farmers in the period May / June and September / October 2010, priority was intentional samples using the technique of "snowball". Structured interviews were conducted semi-structured interviews with 56 urban farmers, and their areas of production were driven method of guided tours, during which we surveyed the plant and animal species that made up and its intended use. When permitted species were also photographed. The botanical material was collected, and forwarded to herbalized IAN Herbarium of Embrapa Eastern Amazon, for identification. The contribution of urban agricultural activities for income was achieved through the use of the tools of the systemic approach of calculations and adjustments in the domestic economy from which we constructed a typology of different production systems sampled. We observed seven different activities in Santarém urban agriculture (agroforestry gardens, fish farming, cultivation of ornamental plants, nursery seedlings of forest, horticulture and mini-farm) activities are carried out in different spaces (backyards, private lots, and side avenues). We recorded the occurrence of 247 plant species grown in different areas of production and 11 animal species, cultivated and raised for different purposes of use. The creation of small animals occurred only within the gardens which has revealed to us, along with the cultivation of food crops, the feeding habits of the farmers who manage and handle. The results provide evidence that analyzed the different activities observed for urban agriculture in Santarém contribute significantly to the income of farmers, either through direct income from the sale of products produced or obtained with the indirect income to the economy arising from the production of foods that are no longer purchased by farmers. Thus we conclude that the importance of the different exercise activities on urban agriculture for farmers varies around the purpose of production and products produced, as well as contribute to the promotion of citizenship, is providing products that improve the quality of life of farm families , is absorbing family labor available, which increases self-esteem of farmers and ensure that they sustain their families in dignity.

Agrobiodivesificacion de playas y barreales y su función en la economia familiar ribereña de la Amazônia Peruana
(Universidade Federal do Pará, 2005-07-14) RIOS ARÉVALO, Michelly; MCGRATH, David Gibbs; http://lattes.cnpq.br/4373475491613670
The present agrobiodiversidad at playas and barreales them of the Amazonian Peruvian it was studied in Muyuy, sector once three hours was located of Iquitos City, the Region Loreto capital. The objective of work was guided to measure the agrobiodiversidad in these expeditious environments and its contribution in the family riverside economy. Firstly, we see than the agricultural activity practiced at playas and barreales them it takes place through a role of production with cultivations of short vegetative period (rice, caupí, peanuts, etc.); this to decrease the risk provoked by the repiquetes or flooding new yearly cycle. Data in the crop years of 1999 and 2004, they allow identifying the establishment of 9 and 2 cultivations respectively, this variation is due to flooding different behavior; variation that at the same time the formation of different environments like playas and barreales them: heights, means, and basses. From now on, we see than optimal barreal environment for the production of rice, it was promoted with agricultural credits - 2004; this implicated logically the incursion varieties certified or overdue ( Inti, Ecoarroz, Jar, Capirona, and Amor 107 ), tender to a fast inundabilidad like the happened in the crop year 2004. The results evidence than communities SPC, ODN, TPZ, CON and DDM benefited with the credits and affected by the flooding, managed to rescue to 10 % of the production expected of rice; find farmers' cases of the communities here DDM and MAZ that used precocious varieties not promoted with credits like the Milagrito also they managed rescue of 50 to 60 % of production. The farmers that established caupí at playas managed to make good use of approximately 10 % of the hoped-for production. The flooding that affected the cultivations near to the period of harvest created propitious environments for nutrition and protection of some fishes and tortoises sorts, this at the same time increased factors or resources of use for the farmers; here, the work of fishing was executed so much for overall consumption and the commercialization for part of some cases found in the studied communities, the more representative like the family shows 11 than as from this work of fishing you got the 2,9% of recuperation on the basis of the profitable calculation from the established cultivations; and of tortoises' capture the 3,1%. It is concluded that the cultivations lost by flooding can be recovered in more significant percentages, if adequate handlings without altering the environments of production be used as it happens with the chemical application of agriculture.

Amphibians and reptiles from Floresta Nacional de Pau-Rosa, Amazonas, Brazil: an important protected area at the heart of Amazonia
(Instituto Nacional de Pesquisas da Amazônia, 2017-09) FERREIRA, Gisele Cassundé; STURARO, Marcelo José; PELOSO, Pedro Luiz Vieira Del
Amazonia harbors the largest and most diverse tropical forest in the world, but knowledge about the species diversity of the region is still far from ideal. Given this low level of faunal and floral knowledge, we present an annotated list of the species of amphibians and reptiles found in Floresta Nacional do Pau-Rosa (FNPR), along the Rio Paraconi, municipality of Maués, state of Amazonas, Brazil. Herpetofauna of the FNPR was sampled with pitfall traps, active search and occasional encounters from February 18 to March 28, 2009. A total of 270 specimens were collected, representing 39 species of amphibians and 24 species of reptiles. At least seven of the species collected at FNPR represented, at the time, unnamed taxa (four of which have now been named). The number of taxa collected and the high number of unnamed taxa highlight the importance of this area in terms of biodiversity and as a priority for conservation. We also discuss about the amphibian diversity in Amazonia.

Análise citogenética em morcegos da família Emballonuridae (Chiroptera) da Amazônia Brasileira através de citogenética clássica e molecular
(Universidade Federal do Pará, 2011-04-29) ARAÚJO, Ramon Everton Ferreira de; PIECZARKA, Julio Cesar; http://lattes.cnpq.br/6644368250823351
This is the first description of the karyotypes of bats of the family Emballonuridae from the Brazilian Amazon region. The species studied were Cormura brevirostris-CBR (2n=22; NF=40), Rhynchonycteris naso-RNA (2n=22 and NF=36), Saccopteryx canescens-SCA (2n=24 and FN=38) and Saccopteryx leptura-SLE (2n=28 and NF=38), characterized by G-, C-banding, NOR-staining and Fluorescent In Situ Hybridization (FISH). In CBR the karyotypes found had the same diploid number and fundamental number than in literature. FISH with ribosomal DNA probes and Ag-NOR staining showed two NOR places. Hybridization with telomeric probes showed that the sequences were found in the centromeres of all chromosomes but the Y. Using meiotic studies, chromosome banding and FISH with a whole X chromosome probe from Phyllostomus hastatus (Chiroptera, Phyllostomidae) we suggest that the sex chromosome pair of this species is not the one described in the literature. Cells in diploid and diakinesis had a ring conformation with four chromosome pairs, what suggests multiple reciprocal translocations among these chromosomes, a very rare situation in vertebrates and never found in eutherian mammals. The analyses of RNA, SCA and SLE shows that the karyotypes of Emballonuridae are very conservative even when compared with samples collected geographically very far, but the C-banding analyses shows that it can happen intraspecific variations in the constitutive heterochromatin. For the first time the Nucleolar Organizer Regions were described, showing a stained pair of chromosomes on each analyzed species. The FISH with 18S rDNA probes agrees with the Ag-NOR staining. FISH with human telomeric probes showed hybridizations in the distal portion of all chromosomes. These works are Important to understand the biodiversity of bats from the Amazon region, as well as the comprehension of the chromosomal evolution of Chiroptera.

Arctiinae (Lepidoptera, Arctiidae) ocorrentes em uma área de pastagem na Amazônia Oriental em Altamira, Pará, Brasil
(Instituto Nacional de Pesquisas da Amazônia, 2013-03) DELFINA, Márcia Cristina; TESTON, José Augusto
This study evaluated the Arctiinae fauna of a pasture area in Altamira, Pará, eastern Amazon, using light traps. The moths were captured at every new moon phase, two nights per phase, from December 2008 to November 2010. We evaluated the following parameters: richness, abundance, dominance, constancy, diversity indexes and evenness (Shannon H' and E'; Brillouin H and E), and Berger-Parker dominance (BP). Richness estimates were made by nonparametric procedures: Bootstrap, Chao1, Chao2, Jackknife1, Jackknife2 and Michaelis-Mentem. We captured a total of 910 specimens belonging to 85 species of Arctiinae. Values of parameters for the total period were: H' = 2.58, E' = 0.581, H = 2.45, E = 0.576 and BP = 0.433. Both richness and abundance were higher in 2009-2010, while diversity and Shannon and Brillouin evenness were higher for the year 2008-2009. Estimators predicted an increase between 18.8% to 85.9% in species richness.

Áreas protegidas na Amazônia brasileira como instrumento de gestão ambiental: a situação do município de Oriximiná, estado do Pará
(Universidade Federal do Pará, 2013) FLORES, Maria do Socorro Almeida; BENATTI, José Heder; http://lattes.cnpq.br/6884704999022918
Creating intervention restricted environments from the expansion of human activities was the model used by industrialized countries to preserve remaining ecosystems of their development process. Brazil adopted this restrictive model through the creation of protected areas, among other instruments. This thesis examines the establishment of protected areas as an instrument of environmental policy in the brazilian Amazon to use as empirical observation units the protected areas in the Calha Norte region, in the State of Pará, which corresponds to a region with low human impact and, as an area located in the endemism guiana region, high concentration of biodiversity, as well as the presence of considerable sociobiodiversity (indigenous civilizations, Quilombola communities and traditional populations). This thesis examines this issue considering the possibility to visualize in environmental management the sustainability of the biodiversity maintaining, which includes respectively the physical basis, the nature resources and the cultural, religious and indigenous peoples ways of life, the Quilombola remaining communities and traditional populations in the region. The primary goal of this thesis is to show that the legal protection of biodiversity and socio-biodiversity is intrinsically related to the concept of bio-responsability, which is based on a set of factors such as legal, political, administrative and economic establish relationships between them to ensure environment sustainability not only as a passive legal good, but as a dynamic allocation process, contributing with the elements to construction of a new meaning for the biodiversity protection, which includes especially the sociobiodiversity by considering the protected areas as one of the instruments for this conceptualization.

Benefícios ambientais e econômicos de sistemas agroflorestais de Tomé-Açu, Pará
(Universidade Federal do Pará, 2023-04-22) SUZUKI, Patrícia Mie; VASCONCELOS, Steel Silva; http://lattes.cnpq.br/0719395243841543; https://orcid.org/0000-0003-2364-8822
The global demand for food and the advance of climate change generate pressure for sustainable production systems that generate multiple benefits. Agroforestry systems (AFS) are productive models with the potential to meet the demands of society and the environment. In this sense, this research aimed to evaluate agroforestry systems' contribution to climate change mitigation, biodiversity conservation, and income generation in the municipality of Tomé-Açu, Pará. Twelve areas of multi-stratified AFS were selected and a 30 x 30-meter plot was installed in each system. An agroforestry inventory and an interview with the producer about the socioeconomic profile and environmental perception of the AFSs were carried out. The data were used to evaluate the influence of plant richness and other variables on the benefits of "Mitigation of climate change", "Biodiversity conservation" and "Income generation", through the indicators aboveground biomass carbon stock, Shannon index (H') and gross income, respectively. For this, we used Principal Component Analysis (PCA) to select the variables and linear regression to create the models. All data from the agroforestry inventory and the statistical analyses were performed in the R 4.2.2 computing environment. In general, 83% of the farmers reported being satisfied or very satisfied with the economic return on the AFSs, in addition to citing several environmental services. Richness (S) per system ranged from 3 to 11 species and Shannon diversity index (H') between 0.55 and 1.77. The average carbon stock of the aboveground biomass in the studied AFSs was 45.2 Mg ha-1, with a variation between 27.4 and 63.0 Mg ha-1. The values of carbon stock in the cocoa, cupuaçu, açaí, dendê, and other components were statistically similar, but differed significantly from the carbon stock found in the forest component (gl=2; χ2=71.7; p=1.834e-13). The average value of annual gross income from the sale of these producers was R$13,758, 53/ha and ranged between R$1,687.50 and R$26,250/ha. In the systems with oil palm (AFSs A1, A2 and A3), the palm tree considerably increased the gross income of the AFSs, contributing 58, 48 and 78% of the total income, respectively, despite the low density of individuals, with an average of 69 ind ha-1, in the areas, in comparison with the other main species. In this study, it was not possible to confirm the influence of plant richness on the generation of climate benefits, biodiversity conservation, and income generation. However, other variables influenced the benefits of the analyzed AFSs. "SAF type", "oil palm density" and "shade species density" performed best on carbon stock, Shannon diversity index and gross income, respectively. As for the benefit scores, in general, most of the AFSs showed unevenly distributed scores for each benefit. Therefore, we conclude that plant richness was not the variable that influenced the benefits evaluated, but rather a set of variables analyzed, ratifying the complexity of Tomé-Açu's AFSs. In general, the AFSs of Tomé-Açu meet the expectations of producers in terms of economic return, besides generating benefits related to climate change mitigation and biodiversity conservation. In particular, the AFSs with the oil palm component showed better performance in the scores of benefits generation.

Biodiversidade bacteriana durante a fermentação espontânea de frutos de açaí (Euterpe oleracea)
(Universidade Federal do Pará, 2015-06-22) MOURA, Fábio Gomes; ROGEZ, Hervé Louis Ghislain; http://lattes.cnpq.br/5202118426597590
Açai (Euterpe oleracea) fruits (AF) and a wide variety of products derived from this fruit are an example of success of a local and typically Brazilian product on the global market. The AF suffer spontaneous fermentation during postharvest due mainly to its high microbial load and the favourable intrinsic and extrinsic parameters. The biodiversity of microbial community in AF and their evolution between three geographical origins and two fermentation conditions were examined. Culture-independent methods based on 16S rRNA from fifteen samples revealed that Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes and Acidobacteria were the most abundant phyla. At genus level, were identified Massilia (taxon with more than 50 % of sequences remaining constant during the 30 h of fermentation), Pantoea (taxon with the highest increase during fermentation), Naxibacter, Enterobacter, Raoultella and Klebsiella, forming the carposphere bacterial microbiota of AF. Attributes related to plant growth promotion (siderophores) and others compounds e.g. poly-3-hydroxybutyrate (PHB) and violacein in response to stress conditions could improve the Massilia preponderance. Beta diversity showed that quality parameters of AF (pH, soluble solids, titratable acididy and lipids) and elemental analysis (C, N, H and C/N ratio) were unable to establish microbial patterns in AF. This research offers new insights and perspectives of the indigenous bacterial community composition on AF as a function of spontaneous fermentation during postharvest.

The study Amazonian Biodiversity and local Markets analyzes the tendencies of the diversified use of the Amazonian Biodiversity in the conceptual bases of development and sustainable production and the potentiality of the local markets as strategic ally. This research sustains that the Amazonian economy can profit from the tendencies of increase in value for natural products, but founded on the high value set on knowledge and involvement of the local population by strengthening the position of the region in its relationships with the national and global markets. A large number of products derived from Amazonian raw materials has been identified, as well as an expressive variety of industrial uses and a favorable, local, national and international atmosphere. There is a conclusive evidence that big enterprises still look upon the external market as their main target inasmuch as the local cooperation ties can still be deemed fragile. The consumers in the city of Belém indicate that the local market is receptive to new products, but it has its own characteristics that demand a renegotiation on the non-traditional trends and uses. And it is well known that the development of an economy system set on diversified bases demands the construction of productive and institutional links as well as adequate public policies, without which many of the emerging initiatives are likely to be unsuccessful.

Biodiversidade e variação espaço-temporal da abundância das populações de camarões e estrutura populacional de Farfantepenaeus subtilis (Pérez-Farfante, 1967) (Penaeidae) em um estuário do litoral amazônico brasileiro
(Universidade Federal do Pará, 2013-04-22) FERREIRA, Valdimere; MARTINELLI-LEMOS, Jussara Moretto; http://lattes.cnpq.br/5264841936875017
This study investigated the biodiversity and spatial-temporal distribution of abundance of populations of shrimp and described the population structure of the Farfantepenaeus subtilis in an Amazonian Estuary. The shrimps were collected monthly from August 2006 to July 2007 in the rainy (January to June) and dry (July to December) season with bottom trawling and beach seine in the Middle-Upper (MU), Medium (M) and Low (L) sectors. In each sector two sites were sampled, of which two bottom trawling five minutes each and three beach seine of 150 m2 each were performed. The variables: temperature, pH and salinity of water and grain size and organic matter of the sediment were analyzed. For each shrimp were recorded the length Total - CT and cephalothorax - CC, total weight, sex and stage of gonadal maturation. The salinity differ between sectors I and MS (p <0.05) and M showed low organic matter content. The salinity differ significantly among sectors I and MS (p <0.05) and M showed low organic matter content. In all sectors the sand grains were prevalent on substrate, especially the fine sand in sector M. A total of 11,939 shrimps were collected, divided into twelve species and six families. Palaemonidae and Penaeidae had higher richness with five and three species, respectively. Penaeidae, Sergestidae and Palaemonidae had higher abundance, with Xiphopenaeus kroyeri, F. subtilis, Acetes marinus and Nematopalaemon schmitti, contributing 43, 31, 21 and 1.3% of the total catch, respectively. The species F. subtilis, X. kroyeri and Litopenaeus schmitti contributed 97% of the total biomass. The density and biomass from F. subtilis differ between the rainy and dry seasons (p <0.05) being higher in rainy season. In the rainy season, the density of X. kroyeri was higher in sectors M and I and dry season in sectors MS and M with higher biomass in sector I in both seasons. The density and biomass A. marinus was high in sector I (p <0.05). The salinity, sand, silt and clay significantly influenced the spatial and temporal distribution of abundance of shrimps (p <0.05). The CC of female F. subtilis was higher than males with 13.7 mm and 12.8 mm, respectively and differed in March (p <0.05). Females were more abundant and sex ratio was 0.8:1 especially in January, February, May and the total analysis (p <0.05). Developed shrimps occurred in rainy and abundance of juveniles was higher from January to June when it occurs the most intense peak spawning in the open sea.

Chromosomal diversity in three species of electric fish (Apteronotidae, Gymnotiformes) from the Amazon Basin
(2014-12) SILVA, Fernando Henrique Ramos; PIECZARKA, Julio Cesar; CARDOSO, Adauto Lima; SILVA, Patrícia Corrêa da; OLIVEIRA, Jonas Alves de; NAGAMACHI, Cleusa Yoshiko
Cytogenetic studies were carried out on samples of Parapteronotus hasemani, Sternarchogiton preto and Sternarchorhamphus muelleri (Apteronotidae, Gymnotiformes) from the Amazon basin. The first two species exhibited both a 2n = 52 karyotype, but differed in their karyotypic formulae, distribution of constitutive heterochromatin, and chromosomal location of the NOR. The third species, Sternarchorhamphus muelleri, was found to have a 2n = 32 karyotype. In all three species the DAPI and chromomycin A3 staining results were consistent with the C-banding results and nucleolar organizer region (NOR) localization. The 18S rDNA probe confirmed that there was only one pair of ribosomal DNA cistron bearers per species. The telomeric probe did not reveal interstitial telomeric sequences (ITS). The karyotypic differences among these species can be used for taxonomic identification. These data will be useful in future studies of these fishes and help understanding the phylogenetic relationships and chromosomal evolution of the Apteronotidae.

A circulação de ideias sobre biodiversidade por professores de ciências e biologia nas abordagens CTS e patrimonial ambiental
(Universidade Federal do Pará, 2014-02-27) GONÇALVES, Adriane da Costa; SILVA, Maria de Fátima Vilhena da; http://lattes.cnpq.br/0996110060293347
The aim of this research is to analyze how the inter-collective ideas about biodiversity circulate in the pedagogical practices of teachers of Science and Biology based on STS and PEE approaches. It aims at identifying and characterizing the Thinking Styles that these teachers have about biodiversity in light of Fleckism epistemology. The present study, a qualitative approach, similar to the Case Study, was attended by 22 teachers from Elementary and Secondary public schools in the city of Igarapé-Miri/Pa. I utilized the methodology of Focal Group as a tool for the construction of empiricism in two Working Groups accomplished during the I Colloquium on Biodiversity, promoted by the Postgraduate Program in Science and Mathematics and for the Group of Studies and Research in Patrimonial Environmental Education. The analysis of this study is anchored in some analytical devices of Discourse Analysis (Orlandi, 2012), Discourse of Collective Subject (LEFÉVRE; LEFÉVRE, 2005) and the Fleckism categories (Fleck, 2010), as analytical tools. For this analyzes, the data were categorized according to approximations and similarities and commonalities of speeches. For identification and characterization of the Thinking Styles presented in the teachers' speeches, I used four elements that constitute the TS, based on Fleckism referential, which are: 1) how to see, understand and realize; 2) Body of knowledge and practices; 3) Sharing by the collective; 4) stylized language. The results indicate the existence of three Thinking Styles on Biodiversity: Biodiversity in the ecological view, Biodiversity as economic potential and Biodiversity as environmental patrimony, being it considered a style in transition, on the grounds that it begins to be thought and designed from the activities of the Colloquium. The analysis also elucidated the conceptions of teachers about the STS interrelationships. These are based on Salvationist perspective of Science, in education for citizenship and as technological resources. The TS in transition "Biodiversity as environmental patrimony" comprises a thinking and an action more critical, because it incorporates environmental issues, social, economic and political aspects in an interdependent relationship and interrelationships among living beings, once its critical dimension is an important element in the STS and Patrimonial Environmental approaches.

The removal or substitution of riparian vegetation causes disturbance in physical environment, seasonal water flow and water chemical quality. These modifications can cause decrease in species richness by local extinctions. The aim of this study was to examine the effect of disturbance in the physical environmental on the richness and species composition of Odonata adults in streams with different levels of conservation in the river Suiá-Missu basin, Mato Grosso, Brazil. Modifications in the aquatic systems affected the Odonata community, probably because their ecophysiological and behavioral requirements of adults and larvae. Anisoptera species, which require sunny environments because of their body size, had higher species richness in environments with low plant cover. On the other hand, Zygoptera species, which generally inhabit streams with dense vegetation, presented a decrease in richness in disturbed environments, as a result high sunlight radiation and/or variations in temperature. Hence, in both suborders, environmental perturbations do not need to be severe to change species composition, indicating that ecosystem services could be lost, even with only partial alterations in physical environment.

Despite academic progress, planning for conservation has failed in performing actions that prioritize biodiversity conservation. New strategies have been proposed to increase the effectiveness of conservation plans, including the realization of decision-making processes with broad participation, facilitate social acceptance of the shares. This article analyzes how information about the threats were used in the decision-making for indicating priority areas for the conservation of the Amazon, in the coordination of the Brazilian Government in 2006 process. First we verified the consistency of information on threats attributed to new areas indicated, and then assess whether the existence, levels and types of threats defined by the participants influenced the indication areas for conservation. The results show that there have been some successes in recognition of threats, but also some inconsistencies, especially in assigned levels and types of low intensity threats such as fishing. The decision making process is also not fully used this information for the indication of areas for conservation. The lack of information about the motivations of these inconsistencies leave no doubt as to the presence of political opportunism, but point out that the participatory process should be allocated a larger effort to combine the participatory decision support systems process in order to generate a priority order more quantitative and less dependent on the individual selection of the participants, to reflect more directly to actual emergency deployment.

The subtribe Luzarina is the most representative in the neotropical region, currently with 128 valid species distributed across 49 genera. In this study, we contribute to the knowledge of the group by describing five new species of Palpigera and a new genus with a new species, Parapalpigera amazonica gen. et sp. nov. The five Palpigera species were identified from 74 specimens collected in different locations in Brazil, including Serra do Cachimbo (PA), Canaã dos Carajás (PA), São José do Rio Claro (MT), Cocalzinho de Goiás (GO), and the Parque Nacional das Sete Cidades (PI). Morphological and internal genitalia analysis revealed that these species differ from other members of the genus in features such as the shape of the palpi, the tenth tergite, metanotal glands, the arrangement of the tympana on the forelegs, vein cells in the tegmina, and the morphology of the phallic complex. These species represent the first records of Palpigera for the northern and northeastern regions of Brazil. Additionally, we describe Parapalpigera amazonica gen. et sp. nov., collected in the Amazon rainforest. This new genus, probably related to Melanotes and Palpigera, is distinguished by its reduced tegmina without a stridulatory apparatus, absence of tympanum, long and thin palpi, shape of the endophallus sclerite, bifid endophallus apodeme, and shape of the female copulatory papilla. These findings expand the taxonomic and biogeographic knowledge of the Luzarina subtribe in the neotropical region.

Description and comparative morphological notes of female terminalia of species of Peckia Robienau-Desvoidy, 1830 (Diptera, Sarcophagidae) from the Brazilian Amazon. In order to contribute and allow specific identification of female of the genus Peckia, the terminalia of 15 species that occurs in Brasilian Amazon are described, illustrated and an identification key to females is given. Besides gena color and the presence of setulae in gena and calypter, the shape of spermathecae and tergite 6 can also be used in the subgenus determination. The sternites 6, 7 and 8, the position of spiracle 6 and the microtrichosity of tergite 6 reveled important to specific identification. The tergite 8 is present only in the species Peckia (Pattonella) intermutans (Walker, 1861). The shape of vaginal plate, a structure present only in four species of subgenus Peckia, differs in shape and can be used to characterize these species. Therefore, a combined analysis of these features of female terminalia is necessary in the species determinationof the females of Peckia. Peckia (Peckia) hilifera (Aldrich, 1916) is recorded for the first time from Brazil.

(Universidade Federal do Pará, 2015-10-08) BORGES, Adriano Dias; MENDES, Ronaldo Lopes Rodrigues; http://lattes.cnpq.br/3384080521072847
For better understanding the Belém's estuary physical aspects is a relevant factor for actions that may develop in the territory. The present study aimed to geodiversity diagnose to give subsidies to better use, exploitation and conservation of natural resources in Cotijuba Island in Belém-PA, thus indicating potential areas for the implementation of public policies mainly in infrastructure and Geotourism. To achieve the goals were made geodiversity aspects thematic maps with subsequent confirmation of the data in the field through raids on Cotijuba Island. Results obtained allow us to make abiotic resources diagnosis on the island, giving a small contribution to the development of public policy proposals with regard to infrastructure and Geotourism, in an attempt to contribute to the local development of Belém island region.
