Percepção ambiental de macrófitas aquáticas e impactos ambientais por estudantes da região metropolitana do Recife, PE Perception of environmental macrophytes aquatic environmental impacts by students of metropolitan area Recife, PE

REMEA - Revista Eletrônica do Mestrado em Educação Ambiental (2014)

Silmar Luiz Silva Karine Matos Magalhães

O objetivo deste estudo foi avaliar como os estudantes de ensino medio da Regiao Metropolitana do Recife, Pernambuco veem as macrofitas aquaticas e os impactos ambientais observados na comunidade onde moram. A partir de questionario semi-estruturado aplicado em 2011, observou-se que 60% dos estudantes afirmam ter visto macrofitas, mas apenas 27% destes sabiam nomea-las. A poluicao e apontada como principal impacto causado, principalmente, pelos moradores, mas com co-responsabilidade da escola e do poder publico. As macrofitas aquaticas sao pouco conhecidas e a proposta de usa-las como ferramenta de analise de percepcao ambiental para este publico nao apresentou resultados satisfatorios. Contudo, constatou-se que os estudantes foram capazes de estabelecer relacoes entre causa e consequencia, principalmente quando referentes aos impactos ambientais sao os vivenciados por eles no cotidiano.

Quantification and classification of the main environmental impacts on a Halodule wrightii seagrass meadow on a tropical island in northeastern Brazil

Anais da Academia Brasileira de Ciências (2012)

Maria Elisa Pitanga Manuel J. Flores Montes Karine Matos Magalhães Thiago N.V. Reis

Multiple stress mechanisms have caused a worldwide decrease in seagrasses, which are vulnerable to environmental and/or anthropogenic pressure. The loss of seagrass meadows of Halodule wrightii is reported for the littoral of Itamaracá Island (Northeastern Brazil). The present study identified the main anthropogenic factors that negatively influenced over the abundance and distribution of seagrass meadows between July and September 2007 at the Jaguaribe and Pilar Beaches, Eastern littoral of Itamaracá. Anthropogenic impact included the discharge of untreated sewage through fluvial channels, urban and commercial development along the coast, the anchoring of motorized and non-motorized boats, diverse fishing techniques and the dumping of solid waste. The data indicates that the Pilar is an environment with a higher impact index (71.43%) when compared with the Jaguaribe (57.14%), standing out the number of boats with a central motor, the total number of boats, the presence of shellfish gatherers and coastal urban development. The present study reinforces the need for defining management and conservation measures for this ecosystem, which has high ecological and economic value.

EFEITO DAS PERDAS DE COBERTURA DE PRADOS DE ANGIOPERMAS MARINHAS SOBRE A MACROFAUNA BENTÔNICA

Arquivos de Ciências do Mar (2019)

Laura Costa Laranjeira Kcrishna Vilanova de Souza Barros M.L. Botter-Carvalho Karine Matos Magalhães

Para avaliar o efeito de perdas recentes de áreas de pradarias marinhas sobre a macrofauna bentônica associada, foram comparadas as assembleias associadas às áreas vegetadas e áreas com perda recente de cobertura vegetal, na praia de Catuama, litoral norte de Pernambuco, Brasil. Em maio de 2010, foram coletadas 10 amostras dentro do prado de Halodule wrightii e 10 amostras em áreas não mais ocupadas pela pradaria (não-vegetadas), com auxílio de um tubo coletor de PVC, para análises das plantas e da fauna capturada em malha de 0,5 mm. A macrofauna bentônica foi composta por 2566 espécimes, sendo 2493 em áreas vegetadas e 73 em áreas sem vegetação. Apenas anelídeos e moluscos foram encontrados em ambos os ambientes, mas a abundância total (H=15,310; p<0,001) e o número de táxons (H=13,740; p<0,001) foram significativamente maiores nas áreas vegetadas. Assim, o estudo demonstrou que as áreas não vegetadas, onde ocorreu perda de cobertura vegetal recente, foram significativamente menos habitadas, reforçando a necessidade de conservação destes prados e, consequentemente, a manutenção de seus serviços ecossistêmicos, como a fauna associada.

Seagrass and Submerged Aquatic Vegetation (VAS) Habitats off the Coast of Brazil: state of knowledge, conservation and main threats

Figshare (2021)

Margareth Copertino Joel C. Creed Marianna Lanari Karine Matos Magalhães Kcrishna Vilanova de Souza Barros

Abstract Seagrass meadows are among the most threatened ecosystems on earth, raising concerns about the equilibrium of coastal ecosystems and the sustainability of local fisheries. The present review evaluated the current status of the research on seagrasses and submerged aquatic vegetation (SAV) habitats off the coast of Brazil in terms of plant responses to environmental conditions, changes in distribution and abundance, and the possible role of climate change and variability. Despite an increase in the number of studies, the communication of the results is still relatively limited and is mainly addressed to a national or regional public; thus, South American seagrasses are rarely included or cited in global reviews and models. The scarcity of large-scale and long-term studies allowing the detection of changes in the structure, abundance and composition of seagrass habitats and associated species still hinders the investigation of such communities with respect to the potential effects of climate change. Seagrass meadows and SAV occur all along the Brazilian coast, with species distribution and abundance being strongly influenced by regional oceanography, coastal water masses, river runoff and coastal geomorphology. Based on these geomorphological, hydrological and ecological features, we characterised the distribution of seagrass habitats and abundances within the major coastal compartments. The current conservation status of Brazilian seagrasses and SAV is critical. The unsustainable exploitation and occupation of coastal areas and the multifold anthropogenic footprints left during the last 100 years led to the loss and degradation of shoreline habitats potentially suitable for seagrass occupation. Knowledge of the prevailing patterns and processes governing seagrass structure and functioning along the Brazilian coast is necessary for the global discussion on climate change. Our review is a first and much-needed step toward a more integrated and inclusive approach to understanding the diversity of coastal plant formations along the Southwestern Atlantic coast as well as a regional alert the projected or predicted effects of global changes on the goods and services provided by regional seagrasses and SAV.

Seascape Habitat Mapping of North-Eastern Brazil Using Sentinel-2, with a Focus on Seagrass

Emma Deeks Karine Matos Magalhães Dimosthenis Traganos Raymond D. Ward Iran C. Normande

Seagrass ecosystems are globally important blue carbon sinks which support significant marine and terrestrial biodiversity. However, human-induced climate change coupled with other anthropogenic stressors have substantially reduced seagrass distributions, making them one of the most threatened ecosystems on Earth. The challenges associated with seagrass conservation include large data gaps and limited low-cost, near-real time methods for monitoring their distribution. Particularly, conservation of the Brazilian seagrass ecosystems and associated biota is severely hindered by the lack of regional scale mapping data. To address this knowledge gap, we used 507 Sentinel-2 satellite images, filtered between August 2020 and May 2021, in the Google Earth Engine cloud computing environment for regional scale seascape habitat mapping. We mapped five states along the north-east coast of Brazil, covering approximately 9,452 km2 of coastline up to a depth of 10 metres. We recorded 328 km2 of seagrass ecosystems along the coast, providing vital open access positional information for a variety of research applications. We also tested whether Sentinel-2 can be used to map temporal changes in coastal habitats and showed a decline of 15.9% of seagrass meadows over a 5-year period in areas of the north-east of Brazil. We demonstrate that Sentinel-2 is effective in mapping seagrass distributions along the coastline at a regional scale and emphasise the importance of replicable and systematic monitoring methods in the race to conserve threatened coastal ecosystems globally.
