    Charles Waters, University of Auckland, Institute of Marine Science Scott Ewing Richard Story, Cook Islands Ministry of Marine Resources Mark J. Costello, University of Auckland Corals are not the only marine organism in trouble. Giant clams are ecologically important because they clean seawater, and their huge shells are home to other marine creatures. They are also a key source of food and income; their vibrant colors make them prize aquarium pets! Due to over-harvesting, many giant clam populations are at the brink of extinction. Giant clams can be raised in hatcheries, but relocating them to coral reefs is challenging. We met that challenge by placing 50 clams in simple, easy-to-build cages for about 3 weeks. Here the clams got protection from predators and water turbulence. Survival for clams inside the cages was much higher than it was for unprotected clams. These results are very encouraging. You can help by using social media to encourage giant clam restoration projects in communities near and far. As you will see, it can be done!

      To protect sea turtles we first must determine where nesting female turtles feed. My research answers this important question for policy makers and conservation managers. Learn more about me and my research at www.Instrumentl.com

          Leading up to the impossible2Possible Lost Coast Expedition, I explore our theme of marine ecology. I've been hiking on the East Coast by the Atlantic Ocean and I can't wait to compare it with the shoreline habitat on the West Coast!

            The first step of this project was to organize a conference on 23 Dec. 2003 in Merjan Motel at Gawader city. The subject of the seminar was “Threat of pollution in Gawader Bay” after completion of the new deep sea port inviting the prominent scientists from the reputable educational, research and conservation institutions (i.e. Karachi University, NIO, PCSIR, Sindh Wildlife, WWF-Pakistan, IUCN)

                The most productive area near the Karachi which falls in Balochistan province territory, should have been the attraction of our government to safe and declare “Marine National Park” instead Islamabad self centred policies and intended future plans to totally destroy ecological growth of the area to full fill some greedy politicians, Bureaucrats, Chaudary, Wadera, business tycoons, and some internationally multinationals desire to suck more blood of the poor people of Sindh and Balochistan

                    'Patterns of top-down control in a seagrass ecosystem: could a roving apex predator (Galeocerdo cuvier) induce a behaviour-mediated trophic cascade?' By: Derek Burkholder, Michael Heithaus, James Fourqurean, Aaron Wirsing, Lawrence Dill http://onlinelibrary.wiley.com/doi/10.1111/1365-2656.12097/abstract This manuscript presents data from a multi-year exclosure study to test a priori hypotheses regarding a behavior-mediated trophic cascade initiated by tiger sharks in a pristine seagrass ecosystem. We present evidence that seagrass communities are heavily influenced by large-bodied grazers, but only in areas where they can graze at lower risk from tiger shark predation. Although recent studies have suggested that roving predators, like tiger sharks, should be unlikely to trigger behavior-mediated cascades our work suggests that spatial heterogeneity can lead to such cascades. This study also suggests that the removal of large bodied predators could have wide-ranging consequeces for foundational species like seagrasses. Therefore, we believe that this manuscript should be of general interest to ecologists working in diverse marine, terrestrial, and freshwater ecosystems.

                      Sea Level Rise Driven by Climate Change and Their Impact towards Indonesian Coastal Ecology Muh Aris Marfai, Faculty of Geography, Universitas Gadjah Mada Indonesian coastline, which is bordering almost 17,000 islands to the sea, extends of more than 80,000 km. Since the coastal area is considered as one of the most vulnerable areas due to the impact climate change, Indonesian coastal area will suffer great damages as the impact of sea level rise enhanced by climate change. This paper aims to assess the impact of sea level rise driven by climate change to the Indonesian coastal ecology, with the focus on coastal area located at northern part of Java Island. At present, some of the cities and districts in northern part of Java have suffering many environmental problems, such as coastal flooding, land subsidence, coastal erosion, and sea water intrusion. Moreover, the mangrove ecosystems in some parts of northern Java also have been damaged due to population stress on coastal area. The impact is predicted to be more severe due to the sea level rise. In Jakarta, sea level rise has been predicted to bring the great damages to the aquaculture ecosystem in coastal area. Multiple impacts of sea level rise towards mangrove, agriculture, and aquaculture ecosystem are predicted to be occurred in Pekalongan. Semarang coastal area also suffers from the spread of health problems which are increasing due to increasing coastal inundation. While in Demak, sea level rise has been predicted to cause major losses on mangrove and aquaculture ecosystem.
