Item Densidade e estrutura populacional do camarão-fantasma Callichirus corruptus (Hernáez, Miranda, Rio & Pinheiro, 2022) (Crustacea, Axiidea, Callichiridae) na praia da Conceição, Paulista - PE após um derramamento de petróleo(2022-10-14) Silva, Wyllyane Gonçalves da; Carvalho, Mônica Lúcia Botter; Matoso, Marcos Antonio Lima; http://lattes.cnpq.br/4408208899837080; http://lattes.cnpq.br/1762304533046987; http://lattes.cnpq.br/2812513561673893During 2019, oil slicks were observed on beaches on the coast of the Northeast region of Brazil and reached about a thousand kilometers off the Brazilian coast. The stains contaminated beaches, estuaries, reefs and mangroves and reached several organisms. This substance is capable of causing high mortality, decreased density and changes in the structure of marine communities. The crustaceans of the infraorder Axiidea, known as ghost shrimp, are burrowing marine organisms, considered important ecosystem engineers and widely used as bait for fishing. The study aimed to analyze the density and population structure of Callichirus corruptus on an oil-impacted beach in Pernambuco, in addition to comparing it with previous studies carried out in the area. Collections were carried out in the months of October/2020, December/2020, May/2021, February/2022, June/2022 and August/2022. The population density of C. corruptus on Conceição beach ranged from 0 to 28 ind/m², with an average density of 6.41 ind/m². Altogether 111 individuals were collected, 28 males and 83 females and 29 of them were ovigerous. The sex ratio was significantly biased towards females. Most individuals had an DO length of 10 to 13 mm, with significant differences between the sexes. For CP and LP There were no significant differences between males and females. The average fecundity was 3844.11 eggs. The present study brought new information from the population of Conceição beach and found that the 2019 oil spill may have caused a decrease in the number of individuals in the population. In view of this, we emphasize the importance of this and other studies related to environmental impacts to which burrowing shrimp are susceptible, as well as encouraging the continuity of research with ghost shrimp.Item Representação da percepção de estudantes sobre o uso de plásticos descartáveis(2020-11-04) Andrade, Yoná Bonifácio da Costa; Schiel, Nicola; http://lattes.cnpq.br/5314455811830714; http://lattes.cnpq.br/9738291524787082Over the years, disposable plastic has been increasingly used recklessly by society. However, its excessive and indiscriminate use has caused great impacts on ecosystems. It is known that environmental perception is an important tool that influences people's attitudes and can be shaped according to socioeconomic factors. Based on this, this research aimed to assess the perception of students in relation to socioeconomic factors, gender and education level, on the impacts caused by disposable plastics. We expected that females and the 3rd year of high school have a greater perception than males and the 9th year of elementary school. The study was carried out in three public schools, in the months of November and December 2019, through a structured questionnaire, with 169 students. Most participants had a perception that favors environmental conservation over disposable plastics, regardless of socioeconomic factors. Students mainly highlighted that students directly affect the ecosystem and the importance of recycling. However, some participants have a negative perception pointing out that plastics are good considering only their usefulness, having a disconnection with the damage caused to the environment. It is assumed that a lack of important gender differences was observed because of social issues coupled with the difference in age of participants. Similarly, in school years, it is assumed that there was no difference in perception because of the grades associated with the high transmission of information via the Internet. Our results indicate that environmental education mechanisms that involve the school community and its surroundings are promising for attitudinal changes that prioritize environmental conservation.Item Perturbações antrópicas e seus impactos sobre a biodiversidade em uma paisagem florestal periurbana(2019-07-18) Belém, Isabela Souto Maior; Silva, Ana Carolina Borges Lins e; Fonsêca, Nathan Castro; http://lattes.cnpq.br/4924065580196245; http://lattes.cnpq.br/7518216414237885; http://lattes.cnpq.br/9316096639439701
