Item Chaves interativas para identificação das famílias Chysobalanaceae e Sapotaceae dos município de Alvarães e Tefé(Universidade do Estado do Amazonas, 2024-02-23) Oliveira, Tereza D'avila Guimarães de; Freire, Guilherme de Queiroz; Souza, Gabriela Oliveira de; Leone, Fernanda Regis; Freire, Guilherme de QueirozThe Amazon rainforest is made up of several groups of plant species, including the Chrysobalanaceae and Sapotaceae families, which are among the main tree families in the Amazon. Interactive keys areuseful tools for recognizing plant species, especially in rich ecosystems. However, there are still few publications for plant diversity in the municipalities of Alvarães and Tefé, AM. Therefore, the present work aimed to develop an interactive key for each one of the Chrysobalanaceae and Sapotaceae families. So, the list of species of Chrysobalanaceae and Sapotaceae from Alvarães and Tefé available on the online platform Reflora – Virtual Herbarium were listed. Each species was described morphologically through specialized bibliography, and its vegetative characteristics were used to construct interactive keys on the XPER3 platform. were listed 30 species of Chrysobalanaceae and 22 species of Sapotaceae, and the most representative genus of each family respectively was Licania and Pouteria. The characteristics most used in the keys were: limbus format, philotaxy, base and apex of the limbus, type of venation, habitus, presence of stipules, latex, glands and other aspects. For both families, the interactive key was considered easy to use.Item Herpetofauna atropelada em duas estradas do Município de Tefé, Amazonas, Brasil(Universidade do Estado do Amazonas, 2024-02-23) Holanda, Rickelmy Martins de; Bernhard, Rafael; Bernhard, Rafael; Freitas, Silva Regina Sampaio; Wilsandrei Cella, Wilsandrei CellaBrazil is widely recognized as one of the world's richest countries in herpetofauna diversity, harboring an impressive variety of amphibians and reptiles across its diverse biomes. However, this biological wealth is increasingly threatened due to a series of factors, including deforestation, habitat fragmentation, and, particularly, the impact of roads. Wildlife roadkill, especially of herpetofauna, emerges as one of the main causes of biodiversity loss along Brazilian highways. In light of this, the present study aims to identify and determine the roadkill rates of herpetofauna species on the roads of Agrovila (AGRO) and EMADE (EMA). Monitoring was conducted weekly in AGRO (N=287) and EMA (N=63), totaling 350 field outings, carried out by 2 or more researchers on bicycles, from August 2017 to August 2023. The recorded animals were identified at the lowest taxonomic level possible. To analyze species richness, rarefaction curves were generated using the CHAO estimator. In AGRO, 1,081 reptiles (647 systematic and 434 occasional) were found, belonging to 18 families and 63 species, with the most affected being Atractus collaris (N=140), Amphisbaena fuliginosa (N=111), Dipsas catesbyi (N=98), Ameiva ameiva (N=97), Erythrolamprus reginae (N=58), and Oxyrhopus melanogenys (N=47). In AGRO, 3,412 amphibians (2,890 systematic and 522 occasional) belonging to 10 families and 37 species were found, with the most affected being Rhinella marina (N=783), Rhinella major (N=695), Scinax gr. ruber (N=613), Leptodactylus macrosternum (N=279), Osteocephalus taurinus (N=180), and Trachycephalus typhonius (N=129). Overall, the roadkill rates (RR) for amphibians were 0.66 individuals per kilometer per day (ind./km/day), and for reptiles, RR was 0.15 ind./km/day. To reduce the impact of roadkill, it is essential to implement preventive and corrective measures, such as installing physical barriers and underpasses. Reducing speed on roads and conducting educational campaigns are also essential to raise awareness among drivers.Item Estudo das Características Epidemiológicas de Leishmaniose Tegumentar Americana (LTA) Notificadas no Munícipio de Tefé, Amazonas, Brasil, no período de 2013 a 2023.(Universidade do Estado do Amazonas, 2024-02-23) Silva, Hellen Karen Gurgel da; Cella, Wilsandrei; Cella , Wilsandrei; Fraga, Eloá Arévalo Gomes; Freitas, Silvia Regina SampaioAmerican Tegumentary Leishmaniasis (ATL) is globally considered one of the top ten neglected tropical diseases, with worldwide distribution, and represents a complex of diseases with significant clinical spectrum and epidemiological diversity. This study aimed to analyze the occurrence of ATL and its epidemiological pattern in patients residing in the municipality of Tefé-AM from 2013 to 2023. For the analysis, data provided by the Municipal Health Department, through the Epidemiological Surveillance Information System (SIVEP), were used in conjunction with additional information from the Notifiable Diseases Information System (SINAN), databases provided by the Department of Health Informatics of the Unified Health System (DATASUS). During the study period, a total of 57 cases of ATL were recorded, representing a prevalence coefficient of 0.91/10,000 inhabitants. The highest incidence rate occurred in males, representing 95% of confirmed cases, with the highest frequency in the age group between 20 and 39 years, representing 53% of cases affected by the disease. The predominant clinical form was cutaneous, with 95% of cases. The variable frequency according to occupation showed a higher number of confirmed cases among agricultural workers, representing 47% of cases. Regarding the area of residence, the urban area showed a higher percentage with 64% of cases. Regarding the evolution of the cases, 92% showed improvement towards cure, and the variable municipality of residence showed a result of 73% of confirmed ATL cases. The analyzed data showed a decrease in cases compared to previous studies, but inconsistencies were found in the information between the data provided by the municipality and DATASUS. The presence of underreporting of data was observed, suggesting that institutions should seek strategies to train healthcare professionals to improve the quality of epidemiological information in the municipality, highlighting the importance of compulsory reporting for more accurate epidemiological data and contributing to the prevention and control of the disease.Item Integração desintegradora- os waimiri-atroari e os conflitos no posto de atração de atração alalaú II em 1974(Universidade do Estado do Amazonas, 2021-12-13) Lima, Rodrigo Aquino de; Santos, Tiago Fonseca dos; Santos, Tiago Fonseca dos; Queirós, César Augusto Bubolz; Filho, Eduardo Gomes da SilvaThis research addresses the conflicts that occurred at the Indigenous Attraction Posts (P.I.A.) in the process of building the BR-174, a highway that crossed the territory occupied by the Waimiri-Atroari, during the period of the military dictatorship. The objective is to analyze and discuss how the resistance on the part of these indigenous people occurred, in the episode that occurred in October 1974 in the P.I.A. Alalaú II, on the Alalaú River. Historical research on the impacts of the military dictatorship in the Amazon has advanced in recent years, however, further studies on the subject are still needed, in addition, this research uses as a source the declassified documentation - once confidential - present in the Archive that was little explored, with this it is intended to contribute to historiography with studies on the subject, given that memory disputes about the period are still in place. With regard to methodological aspects, a qualitative approach was adopted using Content Analysis as a technique for working with sources. In view of this, it was possible to verify that the resistance of the Waimiri Atroari was effective, in that they did not refrain from defending their traditional territory from the invasion imposed by the Federal Government with the advancement of their “development” projects.Item Aspectos da caça e comércio de jacaré (Crocodylia: Alligatoride) no rio Copeá, no Município de Maraã (Am)(Universidade do Estado do Amazonas, 2017-08-25) Chagas, Dorvanir Cruz dasHunting of caimans occur over all amazon basin but are a few studies about this theme. This research was conducted in order to characterize aspects of hunting and trade of alligator meat in Copeá river, taking as a production base, two communities located the banks of this river. The information in this article was obtained through interviews and monitoring landing in the port community. The measures of body size were obtained, weight, species, sex, origin, methods and effort hunting, selling price and destination of the meat. In 12 hunting events, representing 8 days of effort, 35 M.niger and six C.crocodilus was captured. Males was the most hunted than the females. Canoe with “rabeta” was the most utilized to go hunting and harpoon was the unique method utilized to hunting caimans. The average yield per hunter/night was 118 kg of salted/dry meat which yields R$ 294.50. The meat is sold salted/dried, for $ 2.50 a pound and is for the market of Para state.Item Caracterização biométrica de filhotes de Jacaré-açu (melanosuchus niger) da reserva de desenvolvimento sustentável mamirauá (rdsm), Amazonas, Brasil(Universidade do Estado do Amazonas, 2017-08-25) Silva, Fernanda PereiraThe lengthof the puppies crocodilian hatchlings can be influenced by several factors such as incubation temperature, the size of the female, nest typeandgeographic variations. Morphometric analysisis one of the methods that have been used by various researchers to describe various aspects of the biology of crocodilians as sexual dimorphism, allometric relationships, differences between species. Thus, the present study aimed to describe biometric characteristics of newly hatched chicks of Melanosuchus niger of Sustainable Development Reserve Mamirauá (RDSM). Biometric measurementsweretaken11puppiesblack caiman(N =251)from seven water bodies (six lakes and a pipe) three sectors of RDSM. The total length (TL) average puppies black caiman hatchlings was30.25cm (± 11.38). Using thet test Stundent found that no significant difference (p>0.05) for CT of individuals between the three sectors, but significant difference between the nests(p <0.05). The CT of a young black caiman is seven times the size of the head; correlating CT with other measures found a positive correlation between the variables. The relation ship of the variables Total Length (CT) /Head length (CCA) showed higher correlation.Item Levantamento etnobotânico de frutas comercializadas no município de Tefé – Am(Universidade do Estado do Amazonas, 2017-08-24) Gaia, Sâmya Daniele CardosoThis study aimed to do in the ethnobotanical survey fruits marketed in the county fairs Tefé - Amazon, the source extraction of each fruit and its consumption, either food or medicine. Data collection took place from September to November 2012. Questionnaires were applied to merchants of the main trade fairs fruit. This provided a list of these, and highlight 09 species from 07 plant families used in traditional medicine, they are the purple and yellow pineapple (Bromeliaceae), Cashew (Anacardiaceae), Brazil-nut (Lecythidaceae) cubiu (Solanaceae), and jenipapo Purui (Rubiaceae), orange (Rutaceae) and regional melon (Cucurbitaceae).Item Potencial riqueza de anuros na comunidade Bom Jesus, floresta nacional de Tefé - AM(Universidade do Estado do Amazonas, 2017-08-23) Lemos, Márcia Andréa de OliveiraThe aim of the present study was to present a list of anurans from Bom Jesus community located at the National Forest of Tefé, Amazonas state, evaluating the richness and the abundance of them, as well as to register the habitats and microhabitats used by the species. Were registered 26 anuran species distributed in 11 genus and six families. The Hylidae family was the most representative and the most abundant species was Leptodactylus fuscus. The largest richness of species was registered for the forest areas and the main microhabitat used by the anurans was the small shrub. The knowledge on the biodiversity of a conservation unit is one of the basic tools inside of a handling plan, therefore, the data of the present study will collaborate for the construction of the handling plan of FLONA Tefé and for the knowledge of the amphibian diversity from Amazon areas.Item Influência das características do sedimento no sucesso de eclosão e na duração da incubação de Podocnemis sextuberculata, na região do médio rio Solimões, AM, Brasil(Universidade do Estado do Amazonas, 2017-08-23) Aguiar, Antônio Eduardo SantosThis study aimed to analyze the influence of sand characteristics in the hatching success and incubation duration of Podocnemis sextuberculata nests. We collected sand samples from nests (~200g) as well as data on hatching success (percentage of live hatchlings) and incubation duration. From the 200g sample, we took a subsample of approximately 50g. We performed granulometric analysis using nine sieves, which separated the sediment in ten different grain size categories. We calculated sediment characteristics (type, mean diameter, sorting and proportion of each granulometric category) by using the software Gradistat. We analyzed 41 nest samples, of which 19.6% were classified as fine sand and 80.4% as medium sand. Our data suggest that hatching success is higher in sediment with high mean diameter and lower sorting. Besides, hatching success is higher in sediments with a higher proportion of medium sand and lower proportions of fine and very fine sand. However, all these relations were weak and even considering very fine sand, which was the one that best explained variation in hatching success, still 77% of the variation in hatching success are explained for other factors than sand characteristics. Incubation duration was not influenced by the sand characteristics that we analyzed. Other studies are necessary, in order to better evaluate the influence of sand characteristics in the reproductive success of this species, as sediment can affect other characteristics, that we did not analyzed, such as: embryonic development, size, sex and mobility of hatchings.Item Atividade antimicrobiana dos metabólitos produzidos pela Bryophyllum calycinum Salisb, frente os microrganismos Proteus vulgaris , Escherichia coli, e Staphylococcus aureus(Universidade do Estado do Amazonas, 2017-08-23) Amorim, Márcia Pinheiro deAntimicrobial activity of metabolites produced by Bryophyllum calycinum Salisb front microorganisms Proteus vulgaris, Escherichia coli, and Staphylococcus aureus. The leaves of Bryophyllum Bryophyllum calycinum Salisb. ("Coirama"), Crassulaceae, have been used in folk medicine as emollient for boils, burns or other injuries, and respiratory problems and gástricos.Por both hereto research aimed to evaluate the antimicrobial activity against Gram positive Staphylococcus aureus and Gram negative bacteria Proteus vulgaris, Escherichia coli. The Botanical Collection was held in the city of Tefé-AM, the specimens were dehydrated will 350C for 48 hours, being crushed in industrial blender, For every 30 grams of crushed material was added 250 ml of 70% ethanol solvent, such as using the Soxhlet extractor . To the cold extract was used the same proportions of biological material and solvent allowed to stand for a period of 48 hours in a container âmbar.As dilutions of the extracts were used for both 0.4 mg and diluted in 20μl of DMSO subsequently plus 1.96 ml water destilada.Os microorganisms were cultivated nutrient medium (NA) for 24h in an oven at 370C. The growth of bacteria was adjusted from the range of Mac Farland, using the same tube of 0.5 standard concentration, equivalent to 1.5 x108 bacteria / ml. The strains of E. coli and S. aureus and P.vulgaris were sown in Petri dishes containing nutrient medium 90x15mm Mueller Hinton.O experiment was performed in triplicate, was added at 80 l of microorganisms to be evaluated in Petri dishes and seeded with a 90x15mm handle Drigalsk. It was used the technique of diffusion disks ± 0.5 cm were used four disks per plate, were added in three 60 l of extract to be evaluated and fourth control group was added 60 l of DMSO as negative control later the plates were Boda temperature of 37 º C for 24 hours for observation of activity of the extract. Generally the extracts evaluated were effective against microorganisms Escherichia coli, and Staphylococcus aureus and Proteus vulgaris, should be noted however that the best results were against microorganisms Gran-negative Escherichia coli, that for both extraction techniques.
