Item Desenvolvimento de uma infraestrutura em nuvem para monitoramento de ninhos de tartarugas marinhas(2024-03-08) Silva, Wanderson Moura da; Medeiros, Victor Wanderley Costa de; http://lattes.cnpq.br/7159595141911505This Course Completion Work proposes a monitoring system for sea turtle nesting, using the ThingsBoard platform to create a monitoring dashboard. The study seeks to integrate Internet of Things (IoT) technologies and community involvement strategies to improve the conservation of these species, whose existence has long been threatened by various predatory factors. The application on the ThingsBoard platform makes it possible to obtain essential data in real time, such as movement and temperature from devices installed inside the nest. The implemented dashboard will provide a clear visual representation of the status of each monitored nest, automatically generating an alert when critical events occur, such as an excessive increase in temperature or movements that cause the incubated eggs to hatch. The dashboard, in addition to providing crucial information for researchers and environmentalists, will be accessible to the local community through an exclusive mobile application. The project review encompasses ongoing improvement strategies, emphasizing collaboration with local experts and active community participation to optimize the effectiveness of the monitoring application. The central role of the dashboard developed on the ThingsBoard platform is to receive and present data from devices installed in turtle nests, to monitor temperature and movement. This system facilitates understanding and analysis of data, providing insights into the possibility of egg hatching, and contributing to the effective conservation of sea turtles.Item Desenvolvimento de um dispositivo sensor para monitoramento de ninhos de tartarugas marinhas(2024-03-10) Arruda, André Luiz Ribeiro; Medeiros, Victor Wanderley Costa de; http://lattes.cnpq.br/7159595141911505; http://lattes.cnpq.br/7895899500265397The preservation of sea turtles is crucial for marine ecology and global biodiversity, as they play important roles in maintaining coastal and marine ecosystems. Currently, some non-governmental organizations dedicated to this cause monitor nests on beaches along the brazilian coast manually, which requires time and human resources. To streamline this process, this study proposes the implementation of an IoT device equipped with sensors for monitoring sea turtle nests. Utilizing Long-Range, Low-Power (LoRa) communication technology, the device aims to enhance monitoring efficiency and accuracy, thereby contributing to the conservation of these vulnerable species.Item Desenvolvimento de um aplicativo móvel para suporte ao monitoramento de ninhos de tartaruga marinha(2024-03-08) Falcão, Beatriz Carvalho; Medeiros, Victor Wanderley Costa de; http://lattes.cnpq.br/7159595141911505It is notable that the degradation of marine life has been a heavily discussed topic in recent decades, especially in regard to sea turtles. Human actions have caused serious damage to these species in their natural habitat. However, it is possible to mitigate these negative impacts through the use of digital technologies, in the context of developing solutions that aim to preserve these vulnerable species. This project targets the implement of an effective solution that provides support in the monitoring of sea turtle nests, using the Thingsboard mobile application, aiming to facilitate the monitoring activity and the accuracy of the processes involved.Item Concentração de elementos-traço chumbo (Pb) e cobre (Cu) em tecidos de Chelonia mydas (Linnaeus, 1758) no Litoral Sul de Pernambuco, Nordeste do Brasil(2021-08-06) Queiroz, Emily Pereira de; Moura, Geraldo Jorge Barbosa de; Rodrigues, Midiã da Silva; http://lattes.cnpq.br/4953311636839935; http://lattes.cnpq.br/1348666346504103; http://lattes.cnpq.br/9237498056744804Between threats to sea turtles species is the contamination of marine enviroments caused by trace elements wich infiltrate into organisms through food, airways or skin and can be passed on by trophic levels. The species Chelonia mydas has coastal habits whose main diet item is seaweed, which had evidence of accumulation by trace elements. This work determined the concentrations of trace elements lead (Pb) and copper (Cu), in order to know the level of contamination of local individuals and the bioavailability of the elements in habitat. 43 samples of C. mydas liver and muscle organs from the southern coast of Pernambuco, Northeast Brazil, collected from November 2016 to November 2018 were used. The quantification was performed by an Inductively coupled plasma - optical emission spectrometry (ICP OES). Cu showed a greater amount in liver, while Pb was present in a higher concentration in muscle, not being detectable in liver. For Cu, the highest concentration found was 64,683 mg kg-1 (6,389–212,286) while for Pb it was 4,115mg kg-1 (1.4–7,424). The southern coast of Pernambuco showed higher concentrations than other Brazilian states and several areas around the world, showing how other threats to the species mask the impacts of these contaminants, whose accumulation mechanisms need further studies to be fully understood. The values found provide a basis for monitoring the species and contamination of the local habitat.Item Caracterização das propriedades químicas e biológicas do muco cloacal das tartarugas marinhas - Ipojuca/PE(2018-08-24) Souza, Daliana Thaisa Maria Teles de Oliveira; Santos, Ednilza Maranhão dos; Oliveira, Lourinalda Luiza Dantas da Silva Selva de; http://lattes.cnpq.br/5812920432455297; http://lattes.cnpq.br/4538607373477161Sea turtles are migratory animals that travel long distances and have a complex life cycle. They are bioindicators and biocontrol animals, contributing to the maintenance of the marine ecosystem. These animals exert great effort in choosing the spawning site to ensure reproductive success. Of the seven species that exist in the world, five occur in Brazil, and all are classified at some level of threat of extinction. There are many threats that turtles face in order to reach adulthood, one of which is related to marine pollution due to chemical compounds that have become an increasingly common reality for these animals. At the time of spawning the turtle releases a light-colored mucus that coats all eggs, thus avoiding the impact between one egg and another and maintaining cloaca lubrication, however the characterization of chemical properties and toxicity have not been documented. The objective of this work was to characterize the chemical properties, the toxicity of the substance and to identify the heavy metals present in the cloacal mucus of the sea turtles. From August 2017 to October 2018, manual collection of cloacal mucus was performed, which took place immediately after spawning, with the aid of a 15 ml falcon tube positioned below the cloaca. Ten females were sampled, nine from Eretmochelys imbricata and one from Chelonia mydas, in the coast of Ipojuca / PE. These had a physical chemical aspect with turbidity in some samples, their pH ranged from 8.58 to 9.28 with a tendency to be alkaline, through the mortality numbers of Artemias salina nauplii the mucus showed a variation in its toxicity of very Toxic to slightly toxic, the amount of protein varied in the samples in concentrations from 0.27 mg to 5.17 mg, for heavy metals the highest concentrations were for Aluminum (35.5 mg / L), followed by Iron (28 , 7 mg / L) and Copper with (26.9 mg / L) besides these were also analyzed Manganese (16.1 mg / L), Lead (15.7 mg / L), Nickel (14 mg / L), Cadmium (13.5 mg / L) and Chromium (12.1 mg / L). The analysis showed that mucus is a good biological material for toxicity analysis and metal identification, however there is much to characterize in its chemical composition, requiring the continuity of this work to monitor the animals, as well as to evaluate space-seasonal issues of these metals. Mucus may be a good predictor of animal and environmental health.Item Trabalho de Conclusão de Residência em anestesiologia veterinária: anestesia geral em tartaruga marinha verde (Chelonia mydas) para amputação de nadadeira - relato de caso(2023-02-24) Oliveira, Lorenn Costa de; Rocha, Rômulo Nunes; Almeida, Maria Raquel de; http://lattes.cnpq.br/9534617524136303; http://lattes.cnpq.br/1840298267290754; http://lattes.cnpq.br/4816935664741673The Residency Program in the Professional Area of Health in Veterinary Medicine at the Federal Rural University of Pernambuco is characterized as a lato sensu postgraduate course, focused on in-service training and on a full-time basis. This modality lasts for 24 months, equivalent to a minimum workload of 5,760 hours, subdivided into 1,152 hours (20%) of theoretical and theoretical-practical activities and 4,608 hours (80%) of practical activities. The program also includes a workload of 960 hours of activities carried out in public health in the areas of Health Surveillance and Primary Health Care, more specifically in the Support Center for Family Health (NASF-AB). During the second year of residency, it is possible to carry out the experience internship in a period of 01 month, so that the resident experiences routines and realities that were not possible in their home institution. The objective of the first chapter of this work was to describe the theoretical-practical activities carried out in the concentration area at the University Veterinary Hospital (UFRPE) and the activities developed in the Unified Health System. In the second chapter, the objective was to report a case of general anesthesia in a green sea turtle (Chelonia mydas) for fin amputation.Item O uso da esqueletocronologia para estimar idade em tartarugas marinhas(2020-01-03) Filgueira, Maysa Arcanjo; Sá, Fabrício Bezerra de; Guimarães, Elisângela da Silva; http://lattes.cnpq.br/3984004103615974; http://lattes.cnpq.br/5063398024530288; http://lattes.cnpq.br/0769561671220471Sea turtle populations are declining worldwide and human activities are being considered as important factors in decreasing this group. Fisheries carried out directly on foraging sites of the species Lepidochelys olivácea generate high mortality rates for this species. Sea turtle strandings have been a very important tool for studies regarding the negative impacts that occur in the coastal zone. Taking into account the importance of assessing the impacts caused on sea turtle populations, the objective of the present study is to estimate the age for the species Lepidochelys olivacea found on the coast of municipality of Ipojuca - PE, using the skeletochronology technique. 14 individuals were used to carry out the analysis, using transversal cuts of the humerus close to Crista Deltapeitoral and thus testing the method of manual wear to obtain the materials for reading the growth lines. The estimated age of the individuals analyzed was 9 to 17 years. It was observed in a strong correlation between the curvilinear Carapace Length - CCC and the number of growth lines (r = 0.91; P <0.0001). However, the correlation between the CCC and the longitudinal length - CL did not obtain a good correlation (r = 0.7; P <0.0001).
