Item Padrão de atividades e do uso da área de vida de Callithrix jacchus em ambiente urbano: como os fatores ecológicos e antrópicos influenciam na dinâmica?(2022-05-26) Silva, Fernanda Danielle Gomes da; Castro, Cristiane Maria Varela de Araújo de; http://lattes.cnpq.br/8181142206633795; http://lattes.cnpq.br/4921773339837259The home range of an animal can be defined as a location used by an individual or social group of animals to carry out their daily activities, such as reproduction, feeding and social interactions. Considering that environmental and seasonal factors can change the dynamics of the pattern of activities and the use of the home range, the present study aimed to monitor two groups of Callithrix jacchus and identify how they use their home ranges and the patterns of activities performed by them, groups according to seasonality. The groups called Q and Z were observed between August 2014 and June 2015 in the Dois Irmaos State Park (PEDI) Recife-PE. The animals were captured and tagged. Data collection used the instantaneous scan method, applied in ten-minute sessions. The categories that presented the highest frequencies in the Q and Z groups were: displacement, stationary and feeding. Analyzing the monthly data set, it was noticed that the activities of the Q group were carried out most of the time in theforest environment in the months of September 2014 and from November 2014 to June 2015, while in all months of analysis, group Z performed most activities in the zoo area and not in the forest. The diet of the Q group was composed mainly of fruits, while the diet of the Z group included mostly provided foods. Thus, the diet of the Q group was influenced by a seasonal factor such as the fruiting of vegetables throughout the dry season and the diet of the Z group was directly or indirectly influenced by human presence at the study site.Item Distribuição espaço-temporal da meiofauna em uma praia arenosa tropical(2022-10-03) Oliveira, Bruna Rodrigues Fidelis de; Guilherme, Betânia Cristina; http://lattes.cnpq.br/3131730022364100; http://lattes.cnpq.br/8456510680790890Sandy beaches have a high biodiversity and protect one of the most extent environments throughout the Brazilian coast. Presenting a fauna of invertebrates that are resistant and adapt to various changes. Meiofauna is projected by invertebrate metazoan organisms that measure 0.044 mm and 0.5 mm. The research aims to characterize the space-time structure of the medium-phained community based on composition and abundance. The collections were performed on Cup beach during the sea bass and two perpendicular transects were chosen to the waterline and equidistant in 100 meters. In each transect, four average collection points were defined in three portions (upper, middle and lower) and one in shallow infralitoral. In each of these points three replicated medium and additional replicated replicated were collected for analysis of particle size factors, using a 9.6 cm2 internal PVC cylindrical witness. As a sample of the biological material were added to 4% - prepared saline plastic pots. Meiofauna samples were washed through the overlapping geological sieves set, with 500 μm and 45 um laboratory mesh intervals and treches on Dolfuss plates under stereomicroscope for screening and identification of the middle -phanainistic organisms present. The half -black was composed of 11 taxa being: Nematoda, Copepoda, Polychaeta, Oligochaeta, Acoela, Acari, Gastrotricha, Ostracoda, Nemertea, Tardigrated and Amphipoda. The Nematoda group was the most abundant in both months. The total density of months,being higher, varied between the months (July and August) and lower in the dry period (September and November). Among the areas, average and infralittoral medium litoral stand out for the highest densities of organisms. Permanova's result also confirmed the significant differences in the meiofauna community between the months, transects and zones of the nMDS figures viewer. Among the abiotic variables, they confirm the average grain size that stands out having an influence of 68% of the meiofauna community.
