Term Monitoring

Mapping seafloors is a fundamental step for managing and preserving coastal zones. Moreover, in a context of current global environmental changes, new methods allowing long-term monitoring are increasingly required. Various methods have been used to map seafloors, primarily benthic macrofauna and sediment sampling along regular grids or transects, and remote sensing methods. These methods map very different things, do not have the same accuracy levels, and have different costs in time and money. Furthermore, such methods often require the competencies of highly skilled scientists and exclude non-specialists otherwise best placed to perform them. In this paper, we test a method based on Direct Field Observations (‘DFO method’), which can be used by non-specialists, and assess if it is sufficient for mapping and monitoring intertidal habitats. We further compare this method with other conventional ones. The results show that such a simple method is relatively rapid and inexpensive given the results obtained. Moreover, it is particularly suitable for highly fragmented intertidal landscapes where other methods are often very limited. In consequence, in areas such as the European coasts, it can be used by non-specialists, such as protected-area managers, and because it is an inexpensive and quick method long-term monitoring is also possible.

Wildlife crime has huge consequences regarding global environmental changes to animals, plants and the entire ecosystem. Combatting wildlife crime effectively requires a deep understanding of human–wildlife interactions and an analysis of the influencing factors. Conservation and green criminology are important in reducing wildlife crime, protecting wildlife and the ecosystem and informing policy-makers about best practices and strategies. However, the past years have shown that wildlife crime is not easy to combat and it is argued in this article that there are underlying existential “givens” and culture-specific aspects that need to be investigated to understand why wildlife crime is still on the rise. This theoretical article explores (eco-)existential perspectives, Greening’s four givens and selected African philosophical concepts, aiming to understand the complexities behind the prevalence of wildlife crime within global and African contexts.

ResumoAs Alterações Ambientais Globais têm se colocado como pauta de inúmeras políticas e condicionantes culturais, econômicas e sociais em diferentes países no Mundo, sendo refletidas nas perspectivas educacionais. Dessa forma, procura-se, com este trabalho, apontar um cenário de concepção e de prática sobre as alterações ambientais globais no escopo do ensino de Geografia na educação profissional e tecnológica. Nesse sentido, o objetivo da pesquisa se assentou em desvelar os seguintes aspectos: 1) mecanismos metodológicos para as aulas desenvolvidas; 2) eixos analíticos sobre as Alterações Ambientais Globais; 3) instrumentos utilizados; 4) referenciais teóricos; 6) papel do livro didático; 7) enfoques formativos dos docentes. Para isto, foi aplicado um questionário a docentes de uma instituição da rede federal de educação profissional e tecnológica no Brasil, denominada Instituto Federal de Educação, Ciência e Tecnologia. O questionário foi empregado para 11 docentes, apresentando interrogações sobre os itens acima enumerados. Obteve-se como resultado que há o predomínio de aulas expositivas e seminários, as análises sobre o tema ocorrem, majoritariamente, pelas mudanças climáticas e desmatamento, as aulas se baseiam em maior parte nos documentários e gráficos, há a prevalência de referenciais teóricos brasileiros, ocorre a constatação ampla de que os livros didáticos são deficitários e mais de 35% dos professores consideram que suas formações não possuem enfoque para o trabalho com as Alterações Ambientais Globais. Palavras-chave: Prática Docente. Meio Ambiente. Didática. AbstractGlobal Environmental Changes have been placed on the agenda of numerous policies, cultural, economic and social conditions in different countries in the world, being reflected in educational perspectives. Thus, this work seeks to point out a scenario of conception and practice on global environmental changes in the scope of teaching Geography in professional and technological education. In this sense, the objective of the research was based on unveiling the following aspects: 1) methodological mechanisms for the developed classes; 2) analytical axes on Global Environmental Changes; 3) instruments used; 4) theoretical references; 6) the textbook role; 7) teachers training approaches. For this, a questionnaire was applied to teachers of an institution of the federal network of professional and technological education in Brazil, called Federal Institute of Education, Science and Technology. The questionnaire was answered by 11 teachers, asking questions about the items listed above. It was obtained as a result that there is a predominance of expository classes and seminars, the analyzes on the subject are mainly due to climate change and deforestation, the classes are mostly based on documentaries and graphics, there is a prevalence of Brazilian theoretical references, it occurs the widespread finding that textbooks are deficient and more than 35% of teachers consider that their training does not have a focus on working with Global Environmental Changes.

Biodiversity can be useful as an ecosystem indicator for conservation and monitoring, through continuous assessment of its main properties including stability, primary productivity, exploitation tolerance and even global environmental changes. The main purpose of this study was to provide a checklist of the crabs associated with subtidal rocky bottoms at the Vitoria Archipelago, southeastern Brazilian coast. Monthly collections were carried out from February 2004 through January 2006 on three islands at the Vitória Archipelago (23°44’S-45°01’W). The crabs were hand-caught by SCUBA divers during the daytime, in rock subtidal. A total of 3084 individuals were caught, belonging to 42 species, 28 genera, and 12 families, highlighting Mithraculus forceps (1528) and Stenorhynchus seticornis (407) representing more than 60% of the sample. On the other hand, Dromia erythropus, Moreiradromia antilensis, Ebalia stimpsoni, Garthiope spinipes and Tumidotheres maculatus had only one individual sampled.
