Item Diversidade de besouros escarabeíneos (Coleoptera: Scarabaeidae: Scarabaeinae) da Universidade Federal Rural de Pernambuco UFRPE/Sede(2024-10-04) Assis Júnior, José Fernando de; Liberal, Carolina Nunes; http://lattes.cnpq.br/7390869942259612; http://lattes.cnpq.br/8327288458916924Scarab beetles are called "dung beetles", this name was given due to the peculiar behavior of some individuals, these beetles modulate and roll some balls made with the feces of other animals. In Brazil, 786 species included in 69 genera are recorded, and in the state of Pernambuco, 16 species distributed in 8 genera are found. The consequences of the behavior and life cycle of these individuals include several environmental services, such as increased nutrient cycling rate in the environment, soil fertilization and aeration, reduced transmission of some vertebrate parasites by killing larvae and eggs, secondary seed dispersal and contribution of biomass to higher trophic levels. However, environmental disturbances can drastically alter the structure of the community, decrease diversity and lead to the loss of ecosystem functions of scarab beetles. The present study aimed to understand the diversity of scarab beetles at the Federal Rural University of Pernambuco. With approximately 147 hectares of extension, the UFRPE Main Campus has areas composed of vegetation from the Atlantic Forest biome. Three collections were carried out in each season, two collections in August and October 2023, in addition to four collections in the months of January, March, April and May 2024, totaling six collections. To capture scarab beetles, 10 points were delimited at the Federal Rural University of Pernambuco, with a minimum distance between points of 100 m. The area was mapped using the AlpineQuest program and at each of the points a set of two pitfall traps was installed, 3 m apart from each other, totaling 20 traps in the study area. Due to the fall of trees and opening of the canopy, the vegetation structure was modified, making it necessary to change some points for collection during the rainy months. For the ecological analysis, we used the Rényi Diversity Profile, the Shapiro-Wilk test, the Levene test and the Tukey test to complement the results of the Analysis of Variance. Analyzing the baits and seasons, we observed that species diversity was higher in the feces pitfalls and in the rainy season. The analysis of variance for species abundance showed that there was an interaction between the bait and season factors, in other words, the impact of one factor depends on the level of another factor, which was not observed in the analysis of variance for species richness.Item Os números da obesidade no Brasil: uma reflexão sobre causas, impactos e enfrentamento(2024-03-08) Freitas, Ana Beatriz Maia de; Souza, Andréa Carla Mendonça de; http://lattes.cnpq.br/7930636205116799Obesity, a multifactorial chronic disease, is defined as an accumulation of abnormal or excessive fat that can be harmful to health, affecting people of all social groups and ages. It is contemporary, being spread in developed and developing countries around the world. Its occurrence causes, in addition to the consequences of obesity itself on quality of life and health, the development of other comorbidities that are associated with it. Heart disease, high cholesterol, type 2 diabetes, sleep apnea, osteoarthritis, cancer and mental illnesses are triggered or worsened by the presence of obesity. Among the causes of the pathology are the increase in the rate of sedentary lifestyle and the maintenance of eating habits increasingly rich in ultra-processed foods with high levels of sugar, fat and sodium. Likewise, the analysis of the social determinants of obesity is addressed, which contributes to the development of reflections and promotion of the identification of effective solutions to issues that refer to gender, race, level of education, economic inequality and other situations, given that the intensity of chronic non-communicable diseases such as obesity varies according to certain contexts. Based on the aspects mentioned, the objective of this study is to carry out a bibliographical review addressing the main definitions, numbers, projections, causes, impacts and treatment measures available to combat obesity in the country. This is a literature review with searches in online databases such as Google Scholar, PubMed and SciELO, as well as websites of the World Health Organization, Pan American Health Organization and Ministry of Health. The selection criteria were scientific productions with freely available texts, in English and Portuguese and with the time frame of the most accessed publications in recent years. It can be concluded that so far, it is not possible to observe a decrease in the numbers of overweight and obesity in the country. The social determinants of obesity such as gender, social class, income and educational level, for example, must be debated in order to establish strategies to combat the pathology in the population. State intervention with the development of public policies is crucial in the advancement and promotion of a society with healthy habits and which has as one of its pillars the quality of life and effective reduction in obesity rates and its associated diseases.Item Diversidade e período de atividade de besouros escarabeíneos (Coleoptera: Scarabaeidae: Scarabaeinae) da Estação Ecológica do Tapacurá(2023-09-15) Cavalcanti, Juliana Ferreira; Liberal, Carolina Nunes; http://lattes.cnpq.br/7390869942259612; http://lattes.cnpq.br/3551522195847302Scarab beetles are detritivorous insects popularly known as “dung beetles”. They have a varied feeding habit, in general they can feed on feces (coprophages), decaying meat (necrophages) or decaying fruits (saprophages), or even on more than one type (generalist). Besides that, they play a very important role as bioindicators, as they are highly sensitive to environmental changes, undergoing changes in the structure of their community. Deforestation and fragmentation of forest environments are some of the most damaging disturbances to biodiversity by which scarab beetles are heavily affected. The Atlantic Forest is one of the Brazilian biomes in the most critical state of degradation, listed as one of the 36 biodiversity hotspots. The objective of this work was to know the diversity and period of activity of scarab beetles in the Atlantic Forest fragment of Tapacurá Ecological Station (8° 02′ 27.8″S and 35° 11′ 46.3″W), located in the municipality of São Lourenço da Mata, Pernambuco. Two samples were carried between the months of february and march, and march and april, where ten points were determined, distributed in order to form a transect. At each point, a set of two pitfall traps was installed, totaling 20 traps per area. Pitfalls were baited with fresh human feces and rotten bovine spleen. A total of 940 individuals distributed in five tribes, seven genera and 18 species of Scarabaeinae were captured. The most abundant species were Canthon terciae (34.47%), Deltochilum kolbei (23.40%) and Dichotomius guaribensis (14.47%). Of the 18 species collected, only 12 occurred in sufficient numbers to be classified in trophic guilds. Among these, seven were considered necrophagous , five generalists, and none were coprophagous. As for the period of activity, four species showed diurnal activity, four showed nocturnal activity, and another four species were considered of continuous activity. Rényi’s diversity profiles showed that the carrion bait had a greater diversity of species taking into account the most abundant species, and the feces bait was more diverse considering the rarest species.Item Dinâmica comportamental e alimentar de um grupo de capivaras (Hydrochoerus hydrochaeris, Linnaeus, 1766) no Parque Estadual de Dois Irmãos do Recife, Pernambuco, Brasil(2021-12-03) Duarte, Lucas Gabriel Melo; Oliveira, Maria Adélia Borstelmann de; http://lattes.cnpq.br/6104426668816123; http://lattes.cnpq.br/8745900922362045Hydrochoerus hydrochaeris is the largest species of Rodentia order and live in many habitats of South America. Due to your behavioral characteristics and food plasticity they are able to form populations in urban environments as long has the mininum requirements of vegetation and a body of water. The main objective of this work is understand the behavior, landscape use and diet of a group of capybaras living in State Park of Dois Irmãos and on the zoo inserted on it. The group was monitored between September 2019 and December 2019. Behavior data was collected using the instantaneous scan method (scan), the diet items was cathegorized and noted, and the localization of the animals was recorded through direct visualization. The group use most of the time forraging (62,2%), moving (10,1%) and taking mud baths and baths (10,1%). There was two principal areas used by capybaras, with the most visited was Zoo grass área (67,95%) comparing with the Dois Irmãos Weir (32,02%). The most representative item in the diet was the introduced grass (71,59%), then wild grass, aquatic plants and provided food by the zoo employees respectively. The chi square test shows there was relation between time periods and feeding behavior. The results of landscape use and feeding behavior are related to the dry season. We concludes that the results follows the standarts habits of the species, but the presence of the Zoo in the park área and his activities influences the living habits of the capybaras throught the human presence, landscape and flora changes, resulting in behavior and área use changes.
