Estuarine, Coastal and Shelf Science

Coastal lagoons are productive and highly vulnerable ecosystems, but their management is still problematic mostly because they constitute transitional interface between terrestrial and marine domains. The " 4th European Conference on Coastal Lagoon Research - Research and Management for the conservation of coastal lagoon ecosystems, South North comparisons" , was focused on the scientific research on coastal lagoons and the management for their conservation and sustainable use. Selected contributions were considered in this special issue of Estuarine Coastal and Shelf Science " Research and Management for the conservation of coastal lagoon ecosystems" as they deal with three important aspects for coastal lagoons management: (1) the design of monitoring programmes using biological compartments, (2) the ecosystem functioning and the impacts of perturbations and (3) ecosystem trajectories particularly after ecosystem restoration. Here we introduce the selected papers published in this issue, place these contributions in the perspective of the science-management interface and discuss new issues for coastal lagoon management. © 2012 Elsevier Ltd.

Marine inundation hazards in French Polynesia are various and unevenly distributed in the territory; they are strongly related to the physiography (topography, bathymetry, coral reef development) of these oceanic islands. Cyclones and tsunamis appear as predominant processes in the definition of coastal flooding risks for Polynesian people. This study examines the geomorphic impacts of Tropical Cyclone Oli, which struck the western part of French Polynesia in February 2010. Submarine reef erosion is quantified through coral colony degree of destruction and massive coral colony displacement. Sediment transport and beach retreat are quantified, and flow velocities at the coastline are estimated through boulder analysis. Erosion and resilience of a sandy bank (cay) at the reef margin is also considered on Tubuai Island through satellite image analysis and GPS field survey. Outer-reef slope angle appears as a major control factor for coral destruction, with vertical submarine cliffs relatively shielded compared to gentle slopes. Submarine boulder measurements provide valuable estimates of flow velocity profile with depth. Beachrock slab measurements also provide estimates of flow velocities at the reef- beach junction. Combining these different geomorphic markers might be a way to apprehend the flow velocity variation when the cyclone waves cross the coral reef. © The Geological Society of London 2012. Source

Seventeen long series of tidal gravity observations with superconducting gravimeters (SGs) belonging to the GGP network allowed to determine the main tidal waves generated by the tidal potential of third degree in the Diurnal (M1), Semi-Diurnal (3MK2, 3MO2) and Ter-Diurnal (M3) bands with a precision of 0.1%, although the amplitudes of these waves are below 10 nm s -2 (1 μgal). Special analysis techniques have been used to separate M1, 3MK2 and 3MO2 from the neighbouring waves generated by the second degree potential. The 11 European stations form a geographically homogeneous subgroup and it is thus possible to derive some conclusions concerning the ocean tides loading and the body tides models. The results for M1, 3MK2 and 3MO2 are not in contradiction with the recent models and the results for M3 are even in agreement with them. © 2011 Springer-Verlag. Source

French Polynesia has a history of economic dependence on French public transfers. The dependence on military spending grew during the 1960s and 1970s due to France's atomic-testing activities in the Tuamotu Archipelago, which ended in 1995. Since then, the official strategy, stated in the Pacte de Progrès in 1993, has been to promote export and tourism revenues, as a substitute for French public transfers. The strategy has not, however, been successful because the policy measures necessary to reach this goal have not been implemented. High costs and prices due to protectionist policies, the high cost of public administration and the Pacific franc's high real exchange rate continue to have negative effects on export and tourism. © 2010 The Australian National University.

Down syndrome, the most common genetic cause of intellectual disability, is associated with brain disorders due to chromosome 21 gene overdosage. Molecular and cellular mechanisms involved in the neuromorphological alterations and cognitive impairments are reported herein in a global model. Recent advances in Down syndrome research have lead to the identification of altered molecular pathways involved in intellectual disability, such as Calcineurin/NFATs pathways, that are of crucial importance in understanding the molecular basis of intellectual disability pathogenesis in this syndrome. Potential treatments in mouse models of Down syndrome, including antagonists of NMDA or GABAA receptors, and microRNAs provide new avenues to develop treatments of intellectual disability. Nevertheless, understanding the links between molecular pathways and treatment strategies in human beings requires further research. © American Association on Intellectual and Developmental Disabilities.
