Understanding Complex Human Ecosystems: The Case of Ecotourism on Bonaire Ecology and Society
Abel, Thomas; National Taipei University; tabel@mail.ntpu.edu.tw.
It is suggested that ecotourism development on the island of Bonaire can be productively understood as a perturbation of a complex human ecosystem. Inputs associated with ecotourism have fueled transformations of the island ecology and sociocultural system. The results of this study indicate that Bonaire's social and economic hierarchy is approaching a new, stable systems state following a 50-yr transition begun by government and industry that stabilized with the appearance of ecotourism development and population growth. Ecotourism can be understood to have "filled in" the middle of the production hierarchy of Bonaire. Interpreted from this perspective, population growth has completed the transformation by expanding into production niches at smaller...

Utilisation des submersibles en biologie et en ecologie abyssale ArchiMer
Alayse, Anne-marie.
With the advent of deep submergence research vessels (DSRVs) biological and ecological studies of ocean deeps have made great strides. Especially these submersibles allowed to conduct physiological and biochemical experiments on benthic fauna directly on the bottom or on board with alive retrieved animals. A second great interest is the possibility to work in chaotic areas and on microenvironments. Without DSRVs most of measurements and observations obtained on hydrothermals vents would had been impossible. We will present the different equipment designed for the two French DSRVs used during the cruises conducted by the Departement "Environnement Profond" de l'IFREMER to study hydrothermal and "normal" deep-sea ecosystems. We will discuss the new devices...

Diagnóstico de áreas degradadas e plano-piloto de recuperação do rio São Francisco no Bioma Caatinga. Repositório Alice
ALVAREZ, I. A..
A recuperação de áreas degradadas ciliares ao longo do Rio São Francisco é necessária e deve ter caráter prioritário nas políticas públicas. Não se pode postergar esta responsabilidade, cabendo à sociedade o dever de recuperar as margens do rio, garantindo a sustentabilidade e a qualidade de vida das gerações futuras. A observação da paisagem das margens do Rio São Francisco, fornece uma aproximação dos problemas de degradação ambiental que vêm ocorrendo nas últimas décadas. Tais problemas estão diretamente relacionados à ação antrópica. É notória a exploração das matas ciliares para fins energéticos e, após sua retirada, abre-se espaço para atividade agropecuária, sendo esta uma das mais impactantes, pois utiliza o solo até a sua completa exaustão,...

Lagoons are highly productive coastal features that provide a range of natural services that society values. Their setting within the coastal landscape leaves them especially vulnerable to profound physical, ecological, and associated societal disturbance from global climate change. Expected shifts in physical and ecological characteristics range from changes in flushing regime, freshwater inputs, and water chemistry to complete inundation and loss and the concomitant loss of natural and human communities. Therefore, managing coastal lagoons in the context of global climate change is critical. Although management approaches will vary depending on local conditions and cultural norms, all management scenarios will need to be nimble and to make full use of...

Caracterización del estado de la biodiversidad en el municipio Guamá, Santiago de Cuba OceanDocs
Apín, Y. C.; Gómez, L. M..
Se ofrece una compilación de los materiales existentes sobre el status de la biodiversidad del municipio Guamá. Las principales problemáticas ambientales son: la antropización producto de migraciones incontroladas de la población hacia las áreas próximas a la línea de costa, vertimientos de desechos sólidos y líquidos en playas y ríos, deficiente red de alcantarillado, presencia de 14 despulpadoras de café, fragmentación de hábitat, la deforestación, erosión de los suelos e introducción de nuevas especies. Se ofrece un breve diagnóstico de la biodiversidad y tipos de ecosistemas presentes (manglares, pastizales marinos, playas y bahías). La fauna terrestre constituye un grupo muy diverso, dentro de esta resulta notoria la presencia de las aves las cuales...

Potential tradeoffs between ecosystem services related to food production in the brazilian chaco. Repositório Alice
AUGUSTO, M. R. L.; PRADO, R. B.; RODRIGUEZ, D. A.; MONTEIRO, J. M. G.; FIDALGO, E. C. C.; DART, R. de O..
The impacts of human interference in the use and management of land, arouses the need to assess them, in order to bring out the importance of ecosystem services provided by the environment to support life and human well-being. Thus, the general objective of this study was to analyze possible tradeoffs in services (ES) related to agricultural production in Porto Murtinho, MS, which is part of the Brazilian Chaco. The Brazilian Chaco is a cradle of fauna and flora biodiversity, being considered the second largest forest area on the American continent and the largest dry tropical forest in South America, hence the importance of conducting studies in this area. The methodology consisted of three stages, starting with the classification of the ES and collecting...

Research on the barriers and limits to climate change adaptation identifies many factors, but describes few processes whereby adaptation is constrained or may indeed fail to avoid catastrophic losses. It often assumes that barriers are by and large distinct from limits to adaptation. We respond to recent calls for comparative studies that are able to further knowledge about the underlying drivers of barriers and limits to adaptation. We compare six cases from across Australia, including those in alpine areas, rivers, reefs, wetlands, small inland communities, and islands, with the aim of identifying common underlying drivers of barriers and limits to adaptation. We find that the path-dependent nature of the institutions that govern natural resources and...

Towards the development of environmental indices for the Namibian shelf, with particular reference to fisheries management. OceanDocs
Bartholomae, Ch.; Van der Plas, A..
The Namibian Ministry of Fisheries and Marine Resources has the task of collecting and providing relevant oceanographic information for management of their fisheries. However, quality information is difficult to provide because of the complexity of the processes involved in the Namibian marine ecosystem. Nonetheless, there are oceanographic data available that can contribute to fisheries management by improving the general understanding of important oceanographic processes related to fisheries. The focus of this paper is on the development of simple environmental indices that can serve as a measurement or proxy of the state or intensity of certain important oceanographic processes or variables for temporal comparison. These indices relate to oceanographic...

La présente étude est effectuée dans le but d’évaluer l’effet des facteurs du milieu sur la distribution des populations bactériennes entériques dans un milieu lagunaire : la lagune de Bizerte. Un échantillonnage saisonnier, (novembre 2004, février 2005, mai 2005 et août 2005), portant sur 41 stations couvrant toute la lagune ont été réalisés. Les analyses bactériologiques effectuées ont concerné l’eau et le sédiment. Les paramètres physico-chimiques de l’eau ont été mesurés in-situ simultanément aux différents échantillonnages. Aussi, les paramètres climatiques ont été fournis par une station météorologique située à proximité de la lagune. Les résultats obtenus ont révélé que les charges en bactéries sont plus importantes dans les sédiments que dans...
