URI Permanente desta comunidadehttps://repositorio.ufpa.br/handle/2011/9260
Surge em 2014 diante da necessidade de formar profissionais capacitados para lidar com os aspectos ambientais, econômicos e sociais que permeiam a biodiversidade brasileira e, em especial, a da região amazônica. O PPGBC está vinculado ao Campus Universitário de Altamira, da Universidade Federal do Pará (UFPA), suprindo uma importante demanda do ensino superior na região Transamazônica e Xingu.
Área de conhecimento: Ciências Biológicas (Ecologia, Zoologia, Fisiologia, Morfologia, Genética, Botânica, Sistemática, Taxonomia, Filogenia, Microbiologia), as Ciências Exatas e Naturais (Geologia, Matemática e Estatística), e às Ciências Sociais Aplicadas (Economia e Sociologia).

Item Acesso aberto (Open Access) A aplicação do hormônio 24-Epibrassinolídeo promove o desenvolvimento e crescimento de mudas de Genipa Americana L. sob diferentes níveis de sombreamento(Universidade Federal do Pará, 2024-09-20) LIMA, Gustavo Gomes; ALVES, Graciliano Galdino; http://lattes.cnpq.br/8085271321555747; HERNÁNDEZ-RUZ, Emil José; http://lattes.cnpq.br/9304799439158425; https://orcid.org/0000-0002-3593-3260One of the essential factors to start the restoration process of an area is the production of vigorous seedlings of adequate size for their survival, however, several challenges make large-scale production impossible, such as the unavailability of seeds and seedlings. The objective of this study is to analyze the effect of different concentrations of the hormone 24-epibrassinolide associated with different levels of shading on the development of genipap seedlings (Genipa americana L.). Genipap seedlings were used in three shading conditions: 50% shade, 35% shade and full sun. The seedlings were subjected to four concentrations of 10, 20, 30 and 40 nM of the hormone 24-epibrassinolide, maintaining a control treatment, in an experimental arrangement in randomized blocks, with four blocks and five treatments. Data were collected at 30, 60, 90, 120 and 150 days after application (DAA) of treatments, with measurements of plant length, stem diameter and number of leaves. To analyze growth parameters, R software was used, generating a Generalized Linear Model (GLM), and analysis of variance was performed on the results of biochemical parameters, with comparison of means by Tukey's test and to compare environmental and physiological data, a principal component analysis (PCA). Plants maintained at 35% shade showed positive effects on the parameters of height, diameter, number of leaves and lower concentrations of the hormone provided an increase in growth variables. The highest concentrations of biochemical variables were observed in conditions of lower hormone concentrations, under full sun and 50%. The environmental parameters were directly linked to the physiological responses of genipap seedlings. The accelerated development and growth of genipap seedlings is possible under certain shading conditions, and presents positive effects under the action of the hormone, which favors the development of robust plants.Item Acesso aberto (Open Access) Diversidade de mamíferos e aves cinegéticas na terra do meio(Universidade Federal do Pará, 2018-02-28) SACCARDI, Victor; HERNÁNDEZ-RUZ, Emil José; http://lattes.cnpq.br/9304799439158425; https://orcid.org/0000-0002-3593-3260Studies on species abundance are critical to understand the patterns and responses of communities to everlasting effects, like climate change, or transient disturbances, like hunting and deforestation. Millions of people in tropical forests depend on wildlife to ensure their protein intake and their food security. Terra do Meio is located in Pará state, Brazilian Amazon, in the watershed of the middle Xingu river, composing a group of protected areas that receive great deforestation pressure, where traditional indigenous and riverside populations live. In order to describe the diversity of medium and large mammals and game bird species of three Conservation Units, 835 km were covered in nine transects. Comparisons were also made between the areas, ascertaining the impacts of hunting, and proposed recommendations for the monitoring of the biodiversity. Population estimates of the species were obtained by the Distance Sampling method. Indirect data were also collected and camera traps also installed. 47 species were recorded. The results suggest that hunting does not drastically affect wild populations in the area and may indicate that local hunting currently tends to be sustainable. This study reinforces the importance of extensive areas for the maintenance of viable populations and the sustainability of hunting in these regions. This study presents estimates of species density in these areas, and it provides the first information on the diversity of mammals and game birds of Riozinho do Anfrísio Extractive Reserve.Item Acesso aberto (Open Access) Uso de recursos naturais por seis comunidades ribeirinhas da Volta Grande do Xingu(Universidade Federal do Pará, 2023-09-29) SOUZA, Thais Santos; SERRA , Anderson Borges; http://lattes.cnpq.br/9878285735905103; SANTOS, Graciliano Galdino Alves dos; http://lattes.cnpq.br/8085271321555747; HERNÁNDEZ-RUZ, Emil José; http://lattes.cnpq.br/9304799439158425The Amazon basin has a potential for harnessing its water resources, which has been explored by building hydroelectric plants to meet the growing demand for energy generation. However, hydroelectric plants cause great transformations in the use of natural resources, such as fishing and the use of forest resources. This is the case of the construction of the Belo Monte hydroelectric plant (UHE) on the Xingu River, west of Pará. In the research, we studied what changes occurred in the use of medicinal plants, fishing, and hunting after the construction of the Belo Monte UHE, in six communities in region of Volta Grande do Xingu. 45 semi-structured interviews were carried out, with the application of tests with families who live next to the river after the construction of the Belo Monte HPP and who exercise or have already used flora, hunting and fishing activities, both for commercial purposes and for consumption. domestic. The frequency of use of each species for hunting, medicinal plants and fishing was observed. There was a reduction in species appreciated for consumption of fish and wild animals (game). In the use of medicinal plants, andiroba obtained the highest frequency of use. Thus, considering the results, that the use of medicinal plants in riverside families occurred after the construction of the Belo Monte HPP, for fishing and hunting there was a reduction of species appreciated for consumption, and consequently these factors provoke changes in the way of life of riverside families.
