Item Ocorrência de coleobrocas em área em processo de restauração florestal em fragmento de Mata Atlântica nordestina(2021-12-07) Silva, Karina Maria da; Gonçalves, Maria da Penha Moreira; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/4109193403596589Insects have a great capacity to adapt to environmental changes, being the group of animals with the greatest abundance and richness of species on the globe. The Atlantic Forest is an important biome with a rich diversity of phytophysiognomies, but today it is in an accelerated process of degradation, requiring forest restoration actions, as well as knowledge and monitoring of insects occurring in the biome, which can be used as bioindicators of advance succession. The present work had as objective to know the diversity of beetroot insects in a fragment of Dense Ombrophilous Forest under restoration, in the Northeastern Atlantic Forest. The study was carried out in a fragment under the domain of the Recife Botanical Garden, in an area under restoration and in an area of preserved native forest adjacent to the first. The survey of insects was carried out in September and December 2019, using the Carvalho 47-type ethanol aerial intercept trap, installed at a height of 1.5 meters from the ground. Insects were collected using traps in transects that crossed the two areas, comprising the sense of restored area - border - preserved native forest, with 8 sampling points in each transect. In the two collections, 649 arthropods were captured, belonging to 6 orders, with greater abundance of insects of the order Coleoptera, mainly coleoborcas from the families Cerambycidae, Bostrichidae and Curculionidae (Scolytinae and Platypodinae). The family Curculionidae had the highest number of individuals collected, followed by the family Cerambycidae. The conserved native forest area had a greater amount of beetle borers when compared to the restoration area, due to the fragmentation of the environment. It is necessary to continue collecting in the other months of the year to understand the population dynamics of these groups of insects and understand the influence of the environment on their distribution, as well as the continuity of the forest restoration process in the disturbed environment for the local balance of these populations.Item Determinação do status da saúde de mariscos (Anomalocardia brasiliana) em áreas afetadas pelo derramamento de óleo no Litoral de Pernambuco através de alterações histopatológicas de brânquias(2022-06-01) Trindade, Maria Raissa Coelho Marchetti; Silva, Suzianny Maria Bezerra Cabral da; Santos, Fernando Leandro dos; http://lattes.cnpq.br/4992016731387891; http://lattes.cnpq.br/8569566022920336; http://lattes.cnpq.br/9853195908852503Anomalocardia brasiliana is a species of shellfish abundantly present on the Brazilian coast, constituting a traditional activity in artisanal fishing in Pernambuco. However, in 2019, there was an oil spill on the Brazilian coast, so far, there are no studies that assess the health condition of bivalve molluscs after this episode. The objective of this work was to evaluate the health status of A. brasiliana through the identification of histological changes in the gills of these animals collected in areas affected by the oil spill in the Pina Basin (northern coast) and in the Rio Formoso estuary (south coast), both from the state of Pernambuco. Twenty adult animals (10 for each coast) were collected and evaluated via histology to determine histological changes in the gills. In general, several histopathological findings were observed, such as: infiltration; presence of infection; architectural and structural alteration; necrosis and parasitoids, in animals, for both coasts of the state of Pernambuco. Based on the results, it can be affirmed that the adult individuals of A. brasiliana, for both coasts of Pernambuco, have histological alterations of gills that indicate some degree of compromise in the health of these animals and in an unhealthy environment.Item Prospecção ambiental em áreas rurais: o estudo de caso da zootecnia em Paulista - PE(2019-01-15) Oliveira, Marina Ximenes de Lima; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/9673126144809309Agricultural activities are causing environmental impacts and all of those activities generate liquid effluents, which when improperly disposed can cause soil, air and water pollution. In addition, the use of natural resources in a irresponsibly way also causes negative results to the environment. The objective of this study was to determine through one case study, the main environmental impacts and their variables due the zootechnical activities developed in the stretch area located on the banks of the Paratibe River, municipality of Paulista (Pernambuco state) during the months of June, July and August of 2018, using the following methodologies: field check list to characterize the environmental diagnosis; hydrological analysis of the Paratibe river in the aforementioned station for pH measurement, transparency, nutrient concentration; and samples for plankton community analysis to perform the occurrence stimation of each organism identified that is in this work function as bioindicators. Data from the planktonic community were submitted to statistical analysis using the Relative Abundance (RA) and Frequency of occurrence (OF) methods. The impacts evidenced in the area during the months of June, July and August/2018 were quantified respectively with the following total indices: -173, -178, -232 which prove the presence of extreme environmental impacts. The nutrient contents were 2.8 mg/L for nitrite concentration and 39.95 mg/L nitrate, mean concentrations of ammonia in the Paratibe river were 3.995 mg/L and for water transparency measurements were verified values of 30 and 40 cm depth of penetration of sunlight. In the three collected samples of plankton 5 taxa were identified in total (Protozoa, Rotifera, Nematoda, Polychaeta, and Copepoda) plus Diptera larvae (insects). With respect to the Protozoa in this work they were visualized as external parasites of some Copepoda organisms, as well as filamentous bacteria. It was verified that the contents of all the analyzed nutrients exceed the maximum concentrations allowed by Resolution 357 ̸2005 of the National Council of the Environment (Brazilian CONAMA); also, that there is a little variety and less survival rates of plankton in the waters of the Paratibe river and that there is much contamination of solid waste in the studied environmental area. Therefore, the region needs preventive and emergencial measures that will guarantee the conservation of this ecosystem and will help in the development of a sustainable animal production breeding system, capable of providing sanitary security to the producer and the population.Item Efeitos de um processo de engorda de praia sobre a comunidade meiofaunística da zona entre-marés da praia de Candeias (Jaboatão dos Guararapes – PE)(2018) Sena, Luiz Felipe Valença Galiza; Rocha, Clélia Márcia Cavalcanti da; Santos, Érika Cavalcante Leite dos; http://lattes.cnpq.br/1552807658058972; http://lattes.cnpq.br/8971495967943784; http://lattes.cnpq.br/0088518530140540Marine erosion, which is characterized by the retreat of the coastline against the sea, promotes a significant loss of habitat for organisms inhabiting the intertidal zone. At various points along the coast of Pernambuco this erosion is already perceived at moderate to severe levels,and some actions have already been carried out to contain the retreat from the beach line. Recently, a process of containment of the marine erosion in the state of Pernambuco was carried out, aiming first at the most affected areas. This action provided, along a 5.5 km stretch,the widening of the sand strip of the beaches of Barra de Jangadas, Candeias and Piedade by a beach nourishment process. The sedimentary recomposition of these beaches was made through sand dredged from the continental shelf fromadepthof13m.Thisstudyanalyzedtheecologicalsuccessionof meiofaunal organisms (from 0.044 mm to 0.5 mm in size), and the sediments inwhich they live, in the beach of Candeias (Jaboatão dos Guararapes, PE) before and after a process of beach nourishment for up to 90 days after the process.These animals have a biology adapted to the interstitial environment, and can vary according to the variation of the nature and size of the grains. The collections were performed before the beach nourishment, 1 day after, 7, 15, 30, 60 and 90 days after sediment deposition, in the infralittoral and in the intertidal zone. The material was performed in the laboratory through routine techniques for the study of meiofauna, which was identified at high taxonomic levels. This work investigated the effects of this process on the meio fauna community of the beach and its ecological succession, dueto its close relationship with the sediments and their characteristics.It was verified that immediately aftert he process of beach nourishment the sediments were modified, and also the structure of the meio fauna community that colonizes them. This has undergone several changes in its structure, both in species richness and inabundance. Statistical tests showed a tendency to stabilize or even stabilize the community structure in a pattern that is significantly similar to the meiofauna originally existing on the beach. Thus, the results point to a possibility of using meiofauna in environmental biomonitoring programs for coastal engineering actions.
