Avaliação de parâmetros micrometeorológicos, do conforto e da percepção térmica na área urbana da cidade de Belém-PA
(Universidade Federal do Pará, 2012-12-20) SILVA JUNIOR, João de Athaydes; PEZZUTI, Juarez Carlos Brito; http://lattes.cnpq.br/3852277891994862
In the present study evaluated a micrometeorological elements and thermal comfort in Belém, along with an examination of issues of social segregation of urban space, contributing to the research of urban climatology in tropical regions that have a specific climate with a strong effect of seasonality during the year. Were used in the research information obtained by weather stations and microloggers distributed by the city, questionnaires, land cover information derived from satellite images and social typologies of urban areas through literature. Quantitative information was analyzed through numerical interpolations and correlations qualitatively and related information acquired in the field. The results indicated that the areas were the less comfortable heat that had less vegetation cover and greater amount of built and paved areas, while areas more comfortable showed the characteristics contrary to earlier, where it was detected the absence of a standard well defined between the socio-spatial typologies with comfort conditions. There was low heat island intensity on the city as well as strong seasonality of rainfall, air temperature and relative humidity. In the city of Belém much of the daytime was uncomfortable, and the intensity of discomfort varied with the characteristics of use and occupation of urban land.

Hunting is an extremely complex issue, due to the serious impact on the environment, but also because game meat is one of the main sources of animal protein for the traditional Amazonian people. This essay discusses subsistence hunting and the lack of access regarding river communities from the Reserva Extrativista do Rio Iriri to food security policies. It aims to discuss the socioeconomic contribution of subsistence hunting, and to bring evidences of the difficult situation in which these families live while trying to gain access to food products and public services in general. To achieve these goals, this paper embraces the theme from an economic and anthropological perspective, by using ethnographic resources to show evidences of the relations between man and environment, as well as the interaction between the economic sector and the other sectors in social life. For this discussion, the theoretical and methodological support from Maurice Godelier, Karl Polanyi, Pierre Bourdieu, Jorge Gasché Suess and Napoleón Vela Mendoza was used, as well as concepts of microeconomics.

Sea turtles have a long history of human exploitation around the world, which has contributed to the species population decline, along with other threats, mainly by accidental capture during fishing, habitat destruction, and pollution. Currently, interaction with fishing is the largest cause of mortality among sea turtles, followed by ingestion of inorganic material (garbage). The waste accumulation in the oceans, mainly plastic, has attracted considerable attention in recent decades since pollution is a major threat to marine life. In this study, we mapped the occurrence and nesting areas of each sea turtles in the coastal zone of Maranhão; analyzed the frequency of strandings all over the years; and evaluated the impacts on sea turtle populations in the Lençóis Maranhenses National Park, as well as diet composition and ingestion of solid waste. This research includes records of strandings of live or dead animals between 2005 and 2020, coming from the database of the Projeto QUEAMAR – Quelônios Aquáticos do Maranhão - UFMA - Federal University of Maranhão, and bi-monthly campaigns to Lençóis Maranhenses National Park. We observed five species of sea turtles along the entire Coast of Maranhão and reproductive records for two of them. From the impacts observed, anthropic interaction was the most observed factor (n=35), with drowning and amputation being the principal consequences of intermeshing (n=12). Intestinal obstruction caused by ingestion of inorganic material was also frequently observed (n=13). During this research, two Marine Seismic Surveys 3D were conducted to prospect for oil and gas, which coincided with a significant increase in the frequency of strandings in Lençóis Maranhenses National Park, possibly caused by noise pollution through noise swells generated by air cannons. Although the Maranhão coast is covered by legally protected areas, such as the Lençóis Maranhenses National Park and the Cururupu Extractive Reserve, long-term studies with species of international migratory cycle, such as sea turtles, which occupy an important position in the conservation scenario, allows detecting trends and temporal changes, as well as evaluating the impacts of anthropogenic activities in coastal areas.

Contaminação de Podocnemis unifilis (Testudines: Podocnemididae) por agrotóxicos e mercúrio na bacia do Rio Xingu, Brasil
(Universidade Federal do Pará, 2017-02-16) PIGNATI, Marina Teófilo; PIGNATI, Wanderlei Antonio; http://lattes.cnpq.br/1262870406586508; PEZZUTI, Juarez Carlos Brito; http://lattes.cnpq.br/3852277891994862
The occupation policy in the north of the state of Mato Grosso and in the state of Pará, through activities such as gold mining, pasture and subsequent agricultural activities, caused a landscape change and habitat contamination. Pesticides, for example, are on the environment as a result of their use in agriculture and mercury (Hg) is mobilized into the environment through mining, deforestation and biomass burning activities. These contaminants are highly persistent and biomagnifies at each trophic level. Chelonian, because they are long lived organisms can accumulate toxic substances for long periods, are important contamination monitors. Podocnemis unifilis, a chelonian species with wide distribution in the Amazon basin, represent an important resource for riparian and indigenous populations, with wide distribution in the Xingu River basin. This study investigated the landscape changes, contamination of pesticides and Hg in P. unifilis in the Xingu River basin. We selected locations with rivers sources or tributaries in the Xingu River basin, in the states of Mato Grosso and Pará, describing the planted area and the use of pesticides in cotton, sugarcane, corn and soybean crops, as well as deforestation and biomass burned in the historical series from the years 2005 to 2014. Between September and December 2014 fifty specimens of P. unifilis were captured for liver, muscle and adipose tissue. Were evaluated 14 active ingredients of organochlorine pesticides by gas chromatography/electron capture detector (GC/ECD), and total Hg (THg) in the tissues of P. unifilis by cold-vapor atomic absorption (CVAA) spectroscopy. It has been shown that agricultural production as well as the use of pesticides in the Xingu river basin in the state of Mato Grosso are increasing every year, and the most commonly used pesticide was Glyphosate in 2014 (8,055,248 liters). Analyzing the states separately, Glyphosate, Metamidofos, Atrazine, 2,4 D and Endosulfan were the pesticides most used in the state of Mato Grosso and, in Pará state, were Atrazine, Glyphosate, Endosulfan, Chlorpyrifos and Tebuconazole respectively. The states of Mato Grosso and Pará had a significant increase in deforestation and biomass burning between the years researched (2005-2014), especially the city of São Félix do Xingu with 17,686.20 km² deforested only in 2014 and Feliz Natal with a 272% increase in the biomass burning in the last year researched (2014). Eight pesticides were found in the tissues of P. unifilis, including isomers and metabolites (values as mean ± standard deviation): Lindane = 1.39±8.46 ng/g-1; p,p’-DDT = 20.32±24.54 ng/g-1; p,p’-DDD = 4.00±6.96 ng/g-1; p,p’-DDE = 0.95±1.15 ng/g-1; o,p’-DDT = 0.90±3.97 ng/g-1; α-Endosulfan = 3.45±17.73 ng/g-1; β-Endosulfan = 3.81±8.01 ng/g-1; and Endosulfan sulfate = 7.12±12.05 ng/g-1. THg was detected in all specimens (liver: 134.20 μg/g-1, muscle: 24.86 μg/g-1). The type of tissue influenced the concentration of pesticides and THg, and the contamination variations of P. unifilis by pesticides and THg in the tissues were not explained by the interaction between sex and the straight-line carapace length. Comparing the results with current national and international legislation for protein resources, it was verified that the specimens of P. unifilis presented concentrations of pesticides greater than the maximum residue limit for Lindane, ΣDDT and ΣEndosulfan and Hg concentration 100 times greater than the acceptable maximum. It was concluded that the crops are "agrochemical-dependent" and that specimens of P. unifilis are contaminated with organochlorine pesticides and Hg. Riparian and indigenous population of the Xingu River basin that consumes these chelonians may be gradually contaminated, with future consequences for health.

Efetividade de gestão da área de proteção ambiental Triunfo do Xingu: desafios de consolidação de uma unidade de conservação na região da Terra do Meio, Estado do Pará
(Universidade Federal do Pará, 2013-07-01) COSTA, André Luis Souza da; PEZZUTI, Juarez Carlos Brito; http://lattes.cnpq.br/3852277891994862
The APA Triunfo do Xingu is located in the region of the Terra do Meio southwest of Pará was established in 2006 with approximately 1,670,000 ha is embedded in a region with important remnants of Amazonian biodiversity. The region suffers major anthropogenic pressure, mainly by deforestation due to illegal logging, the advance of cattle and burned. The existence of a protected category in the APA in a region with high levels of environmental degradation and land grabbing as the region of Terra do Meio is hotly contested as an effective instrument to protect biodiversity and land use. The study aimed to develop and implement a model of management qualification of the APA Triunfo do Xingu based on the concept of effectiveness management in order to assess whether it is meeting the objectives that guided its creation. Indicators were developed and grouped into six themes: environmental management, economic, legal, political, institutional and socio-cultural, and subsequently qualified in three levels according to their respective scenarios. The result demonstrated the degree of management effectiveness of 54.3%, current conditions management APA Triunfo do Xingu were considered moderately satisfactory. The politico-institutional indicator was the best punctuated with 66.6%; indicator law and management had, respectively, the averages of 55.5% and 54.4%, sociocultural and environmental indicators had, respectively, the average 49.9% and 47.1%, and the economic indicators recorded an average of 33.3%, and the group with the worst performance management. There was a condition of high vulnerability of the APA Triunfo do Xingu does not guarantee its existence and long-term conservation objectives that guided its creation can hardly be achieved under these conditions.

The present work aims to demonstrate the central variability in forest in relation to stocks and forest carbon biomass above ground, from the identification and characterization based on remote sensing, landscape units in an area located in the municipality of Belterra, western Pará State, from the theoretical-conceptual approach of landscape ecology. For the scope of this proposition, the methodology used was based on the literature review on the topic, data acquisition and orbital mapping, use of remote sensing techniques, field data collection, processing and statistical analysis. The work is divided into four chapters, followed by general considerations of the work. Based on the theoretical-methodological of Landscape Ecology, analyzes the social and environmental dynamics of the municipality of Belterra, who currently experiences the expansion of agricultural activities, especially agriculture mechanized soy. From the analysis of multi-temporal Landsat images of the city we could assess the distribution of existing forest cover in the same as well as the spatial distribution of the main landscape units identified. Considering this clipping was held to collect field data via forest inventory in four forest types (forest high plateau, low plateau forest, secondary vegetation and ecological tension) to obtain morphometric parameters of vegetation and subsequent quantification of stocks biomass and carbon contained in each unit as well as observe the structural behavior of the same forest. The adoption of the landscape as the spatial scale of analysis proved to be quite satisfactory in the quantification of biomass and carbon stocks of forest to allow considering the influence of socioeconomic dynamics in reducing these stocks. Furthermore, analyzes showed that recognition of the heterogeneity of forest cover is an essential element for obtaining carbon estimates according to the structural characteristics of vegetation which varies with the topography of the terrain, with the species present and the geographical features, which involves the type climate, geomorphologic characteristics, soil and geological area.

Etnoecologia, pesca e manejo comunitário de quelônios aquáticos na várzea do Baixo rio Amazonas

The aim of the present study was to describe, record and compare community management strategies for aquatic turtles in three communities of the Santarém floodplains, in the north of Brazil. Turtle consumption was also assessed in terms of preferences, rejections, food taboos and their use in popular medicine as a therapeutic resource. The turtle fishing techniques used were described, including seasonal and spatial variations, as were the species captured and the technique selection process, based on local knowledge. The income from fishing and the association between investment and return were assessed. The data were collected between June 2007 and July 2008. Informal conversations, monitoring of fishing activity and participant observation were carried out in the communities. Semistructured interviews, based on the dietary recall method (recall history), were also performed. These interviews recorded annual turtle consumption as well as memories of turtle fishing in the past. The first reports of turtle management in the Amazon region were made at the time of the first contact between Amerindians and Europeans. During the 1970’s, the Brazilian government implemented reforms based on centralized management controlled by the State. Currently, co-management exists in various locations of the Amazon region, such as the communities of Ilha de São Miguel, Costa do Aritapera and Água Preta. Although guided by community demand, the management of these three communities differs due to different levels of experience with management systems. On Ilha de São Miguel, turtle management has been present for almost 40 years, with a certain degree of success and vigor. Management techniques were established in Água Preta 22 years ago in a less rigorous manner. The recent implementation in Costa do Aritapera was not successful. In general, the inclusion of the main users of a natural resource in its management is difficult to execute. The great challenge for turtle management, as well as other wildlife resources in the Amazon region, is legal recognition of their use. Turtle consumption is a tradition rooted in Amazonian culture. However, it has been criminalized and as such, the majority of the population is constrained from doing so. As it is considered an illegal activity, there are no estimates of the quantity of animals exploited. This causes problems to those who want to implement sustainable methods of community management. Studies have shown that fish constitutes the main source of animal protein for the people of the Amazon region, whereas records of turtle consumption are relatively low. Differences were found in terms of the species of turtle consumed. In general, tracajá (Podocnemis unifilis) (meat and eggs) was the most commonly consumed species in the three communities, followed by pitiu (Podocnemis sextuberculata) (meat and eggs), which was mainly consumed in Costa do Aritapera. Turtles (Podocnemis expansa) are rarely consumed and there were no records of their eggs being collected. This meat is mainly consumed on Ilha de São Miguel. These differences could be associated with a combination of ecological factors and the management history of each community. No cultural differences were found between the communities in terms of the use of turtles. Podocnemis expansa, which is principally used in popular medicine, is the most rejected species whereas tracajá and pitiu are generally preferred. All three are considered to be “reimoso”. The most captured species was tracajá, followed by pitiu and tartaruga in lesser proportions. Tracajá can be found in different environments and collected at any time of the year in the three communities. Pitiu are mainly captured around Costa do Aritapera in periods of low water season. At this time, they are migrating from flooded forests areas in the direction of rivers and nesting beaches. Tartaruga are caught in the protected lakes of Ilha de São Miguel in times of flood. The fishing techniques employed vary depending on the level of the river. The fishermen recognize seasonal variations and, combined with local knowledge, use this information when selecting the technique to be used to catch turtles. Turtle fishing is usually carried out in a timely manner, during fishing expeditions. The yield of turtle fishing is greater when fish are not included and fishing by hand. Fishing by hand was more fruitful. Selective fishing aimed at capturing larger animals produced greater returns in terms of biomass. The yield based on CPUEN differed between the communities and the fishing periods in the present study, although there were no significant differences when biomass was calculated (CPUEB). The fishermen, in general, are not concerned with maximizing their income, because most fisheries are not for marketing. The yield reflects more the wisdom of a good fishing spot than the effort of displacement.When the patch was good fishermen spent little time while in less productive patches they spent more time. The present study suggests a number of ideas that could be adopted in order to facilitate the success of fauna community management. In the specific case of turtles, it is recommended that protected areas extend beyond the nesting areas and a quota system is introduced to take advantage of eggs that will be lost. There is a possibility of breeding commercialization.

This work aims to analyze the insertion of the Amazon economy into commercial capitalism based on faunal extractivism in the period from 1759 to 1830, which comprises the stage of conquest and consolidation of the territory. To this end, the process of producing data relating to faunal extractivism in the Brazilian Amazon during the time frame established, the participation of faunal extractivism in the dynamics of Brazil's insertion into mercantilism, the Portuguese colonizing model in the Brazilian Amazon, and finally, the role of faunal extractivism in the insertion of the Amazon Valley into the dynamics of mercantile capitalism, from the perspective of the organization of the workforce. The originality of this documentary research is evident in the volume and extent of the collection consulted, the length of the time frame, the scope of the territorial scope, and the diversity and volume of faunal resources researched, which encompasses Amazon turtle fishing and collecting eggs, fishing for manatee, arapaima and mullet. As a novelty, the use of alligator oil for lighting and as an ingredient in mortar compounds for buildings. The topic is approached from a heterodox theoretical basis, which allows discussing the Portuguese administrative model in the Brazilian Amazon, the mechanisms of subordination of the colony to metropolitan power, vicissitudes and influences in contemporary Brazilian society. The issue of the mode of production via compulsory labor and the mechanisms for appropriating indigenous technology is used as a canvas for the discussion about the centrality of faunal extraction for the colonization of the territory. The relative silence of economic historiography regarding the centrality of activities that enabled the production of products considered central in the study via economic cycles is questioned. As a strategy, this work provides a brief histographic review of the first economic activities carried out in Brazil – the trade in human beings and fauna. The results reveal, in summary, that without indigenous technology, which includes the knowledge that enabled faunal extraction, it would have been impossible for the Portuguese conquerors to consolidate their dominance over the territory and enable economic activities aimed at meeting the demands of the external market.

In turtles, the characteristics of the nesting environment have a strong influence on the incubation temperature of eggs and, consequently, on the reproductive success. The effects of the enviroment of nesting on the hatching rate, the duration of incubation and the sexual determination of the nestlings of Podocnemis expansa, Podocnemis unifilis and Podocnemis sextuberculata in the Embaubal nesting beach, Xingu River, Pará State, Brazil, in 2007, 2008 and 2010 were investigated. Nesting beaches were continuously visited between September and January, in order to monitoring nests marked in the first day after oviposition, in each reproductive season. The following features measured: day of spawning, depth to the first egg, The nest’s height in relation to the river level, granulometry and temperatures of inubation. The hatching rate differed between years for the three species. The duration f incubation varied only between years P. sextuberculata. The sex ratio of P. expansa in 2007 was 0.08 and in 2008 and 2010 all the nestlings were females. In P. sextuberculata sex ratio in 2007 was 0.34, and in 2008 and 2010 was 0.06. The sex ratio of P. unifilis in 2007 was 0.41, 0.65 in 2008 and 0.02 in 2010. All of these differences were significants statistically. The nest’s height in relation to the river level presented positive correlation with the hatching rate of the three species in 2008 and a negative relation with the hatching rate of P. sextuberculata in 2010. The number of days after the beginning of the spawnings influenced the duration of incubation of P. sextuberculata and P. unifilis in 2008. The average temperature, the number of hours/degree above of 32°C and the size of the sediment influenced the sex ratio of P. expansa. The results attest to the variation in hatching success, embryo development and sex ratio produced between years. Still, it was observed that the influence of microclimatic variables of the selected sites for nesting in nesting success and sex ratio varied between years, which is a clear evidence that climatic conditions plays a major role and causes changes in the parameters examined thorough a nesting season and between nesting seasons in subsequent years. It is recommended the continued monitoring of the related parameters in the main areas which is invest the protection the reproductive sites of turtles.

Integrando conhecimentos locais e armadilhas fotográficas para avaliar a detecção e as características ecológicas que afetam a presença e a abundância de vertebrados médios e grandes no Vale do Xingu, Amazônia Oriental
(Universidade Federal do Pará, 2024-10) VULCÃO, Otávio Augusto Pereira Leão; CARVALHO JUNIOR, Elildo Alves Ribeiro de; http://lattes.cnpq.br/7456274393700395; HTTPS://ORCID.ORG/0000-0003-4356-2954; PEZZUTI, Juarez Carlos Brito; http://lattes.cnpq.br/3852277891994862; https://orcid.org/0000-0002-5409-8336
The choice of appropriate methods to observe population changes of species of interest in environmental monitoring is crucial to ensure the sustainability of long-term programs. This is a challenge in assessing medium and large vertebrates due to their ecological importance and relatively high costs for evaluation. In tropical regions, the methods commonly used are transect censuses or camera traps. However, both methods have limitations and can incur high costs and difficult maintenance, especially in megadiverse tropical countries. Including methods based on local ecological knowledge (LEK) can contribute to the sustainability of monitoring programs. We assessed the congruence between detection rates obtained from camera traps and sightings and traces detected through LEK in two protected areas of Eastern Amazonia, comparing detection probabilities and testing the influence of three ecological traits. We observed that, despite an overall positive relationship, the rates obtained by both methods show high variability. For 11 out of 20 species, the probability of detection was greater using the method that identified traces through LEK from local monitors. Among the selected traits, body mass, sociability, and trophic niche, only the last characteristic was significant within our models, indicating a detection capability primarily based on the behavioral patterns of the species. Our results demonstrate the significant ability of local monitors to detect the presence of species of interest, as well as the applicability of LEK in faunal monitoring. We recommend collaborative research strategies and the inclusion of the knowledge and experience of local populations in monitoring and conservation programs in the Amazon and other tropical systems, which are the regions richest in both biological diversity and sociocultural richness.

Fire is a constant in rural areas throughout the Brazilian Amazon, both as intentional burning and accidental fires, which entails a constant threat to human survival and the integrity of forests. The human activity of opening up the agricultural frontier in this region, characterized by the predominance of extensive systems of land management, consists in the main source of ignition of accidental fires. The phenomenon called fire contagion occurs when fire escapes out of human control and reaches neighboring areas of forests and rural productive units. The main objective of this work is to present a theoretical-methodological framework that adequately addresses the behavior of peasants of the Brazilian Amazon, more specifically with regard to their decision-making process of land management for production, as regards to fire use as an agricultural technique, as well as their reactions to the fire contagion in their units. The model of reproductive efficiency of Costa and the field theory of Bourdieu are taken as theoretical-methodological references. The subfield of peasant production in the Brazilian Amazon hosts the field work for primary data collection of peasants settled along the federal highway Cuiabá - Santarém, known as the BR-163 Corridor, covering areas of the territories of the Brazilian States of Pará and Mato Grosso. Statistical techniques, such as regression with dummy variables, tests based on Chi-square statistics and logistic modeling supported the individual and joint analyzes of the determinants, empirically identified as explanatory variables of peasant behavioral decision making for fire use and their reactions to fire contagion. The results on both subjects (use of fire and accidental fire) confirm the guiding hypothesis of the present work, which claims that that peasant behavior, as a decision maker of the productive unit is constantly influenced by the sociocultural and institutional environment, without however ignore their specificities as peasant units.

The Amazon has a high diversity of medium and large vertebrates, which are essential for forest dynamics. They stand out for being the most hunted by local human populations and, as a result, it is likely that changes in the composition, wealth and abundance of this group of animals will occur throughout the territory. This human-animal interaction creates disturbances for both parties, reducing the chances of direct or indirect encounters, causing losses to the subsistence hunting of local communities. Due to this situation, the ability of wildlife to persist in areas of varying human densities is discussed, especially in protected areas, and it is necessary to establish monitoring programs to understand and deal with the threats mentioned above. This work sought to evaluate the feasibility of using trails of residents (TM) for monitoring vertebrates, comparing the results obtained in trails of researcher of the protocol TEAM (TPt) and trails of researcher of the Minimum Protocol (TPm). An Non-Metric Multidimensional Scaling (NMDS) analysis, rarefaction curves and richness demonstrated that there was a significant difference in the composition of species obtained in TM, TPt and TPm. Despite the significant difference between the areas, the richness and abundance data in TPt were more stable among all registered species, in addition to showing a similarity with the richness and abundance data obtained in TM. Therefore, it is possible that future monitoring actions may take place in the trails of residents present in extractive reserves.

The world's social environmental crisis requires other forms of society's relationship with nature. More integrated models of Economy and Society to nature have become a challenge. Facing this necessity, look for people who maintain a close relationship with nature even in the context of modernity, may indicate possible ways. The overall goal of this study was to understand how the perception and the relationship between Agua Preta community (Santarém, Para) with aquatic fauna can contribute to management and conservation plans. The specific goals were: 1) to understand the historic construction of the relationship between the Agua Preta community people and the aquatic fauna; (2) to comprehend the starting up of conflicts involving community and the aquatic fauna; (3) to investigate how conflicts involving the aquatic fauna affects the management possibilities; 4) to demonstrate and understand plural values existing on the relation between riverine people and aquatic fauna ; 5) to verify how the plural values existing on the relationship between riverine people and aquatic fauna affects the possible ways of use and management of natural resources; 6) to establish the correlation between the perception and relationship of the Agua Preta comunity residents and the aquatic fauna with local comprehension of development. The methodology was based on the local resident’s perception, through direct observation, open and semi-structured interviews and documental analysis. The results showed that the collective identity of Agua Preta community is a mobile identity that can combine historical social values with the transformations of the scenario where they are living. This kind of identity has implications on the established relation with the aquatic fauna, on the perceptions and on his attributed values, enhancing the values plurality. This plurality is associated to the resilience capacity of the group, but is also associated to the vulnerability increasing, because of the increase empowerment of different interests. On this way, a historically resilient management system would have more and more reduced his capacity of response. In spite of this, the reconstruction of community adaptive capital based on the social memory and the social learning can help this community to recover and reinforce his adaptive way of management and governance of his resources. The conclusion is that the way of living of Agua Preta community can show the way to different forms of development beyond the modernity.
