| 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... |

| 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... |

| 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... |

| 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... |

| 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... |

| The European Multidisciplinary Seafloor and water-column Observatory (EMSO) European Research Infrastructure Consortium (ERIC) provides power, communications, sensors, and data infrastructure for continuous, high-resolution, (near-)real-time, interactive ocean observations across a multidisciplinary and interdisciplinary range of research areas including biology, geology, chemistry, physics, engineering, and computer science, from polar to subtropical environments, through the water column down to the abyss. Eleven deep-sea and four shallow nodes span from the Arctic through the Atlantic and Mediterranean, to the Black Sea. Coordination among the consortium nodes is being strengthened through the EMSOdev project (H2020), which will produce the EMSO Generic... |
