The community role is needed in the implementation of mangrove forest tourism management, especially in planning activities. The role of the community is the involvement of community itself in the development activities, both in the planning, implementation, evaluation, and the stages of esnjoying the results of the development itself. The purpose in this descriptive qualitative study was to determine the role of community in managing mangrove forest tourism in the subdistrict of Sukadana of Kayong Utara regency. Data collection techniques consist of observation, interviews, and documentation. While the analysis was carried out with descriptive analysis technique. The results of this study indicate that the role of of the sejahtera village community in managing mangrove forest tourism is limited to the maintenance of natural resources, maintenance of cleanliness and nursery of mangrove forests. Due to mangrove forest management is still fully managed by The Gunung Palung National Park Agency, the role of the community in the management of tourism in mangrove forests is still low. Therefore, the involvement of the surrounding community needs special attention and other related parties in utilizing mangrove forest tourism.Keyword: community role, mangrove forest, themanagement of mangrove tourism

Fishery Science

In 1960th, red king crab was intentionally introduced into the Barents Sea. This species has formed a new self-sustaining population. In Russian waters, the commercial fishery of red king crab was started in 2004. Non-indigenous status and high commercial value of the crab have led to growing interest in the study of its biology and ecology. Red king crab has been intensively studied by specialists of Murmansk Marine Biological Institute to evaluate the role of this crab in local benthic communities and provide a theoretic basis and important applications for fishery science. New data on the population dynamics, symbiotic relationships, feeding and reproduction of red king crab have been obtained from long-term studies in coastal waters of the Barents Sea. Significant results of these studies are presented in this review.

Mangrove forest has physical, biological/ecological and social-economics functions. Mangrove forest at Pulau Pahawang Village, Marga Punduh, Subdistrict Pesawaran has many functions which causes many interest of actors. This research was aimed to identify and maping the role of actors interest. This research was conducted on August until October 2015, by using key informant namely agencies village, local communities, public figure, related department and Non-Governmental Organizations (NGO).             The result showed that there was six important aspect namely the existence of the green belt, kind of variety (biodiversity), education facilities, fire wood, non-timber forest product, and tourist facilities. Pulau Pahawang Village has three quadrant matrix interest, quadrant subject has State Ministry of The Environment. Quadrant keyplayers has Department of Forestry and Estate Crops, Mangrove Protected Area Management Agency (BPDPM), and Mitra Bentala as NGOs. Quadrant crowd has Development Planning Agency in Sub-National Level, Land Agency, Department of Maritime and Fisheries Affairs, Regional House of Representatives, and local. Keyword : actor interest, mangrove forest, Pulau Pahawang, role of actor

Beach Cast

Sandy beaches are iconic interfaces that functionally link the ocean with the land by the flow of marine organic matter. These cross-ecosystem fluxes often comprise uprooted seagrass and dislodged macroalgae that can form substantial accumulations of detritus, termed ‘wrack’, on sandy beaches. In addition, the tissue of the carcasses of marine animals that regularly wash up on beaches form a rich food source (‘carrion’) for a diversity of scavenging animals. Here, we provide a global review of how wrack and carrion provide spatial subsidies that shape the structure and functioning of sandy beach ecosystems (sandy beaches and adjacent surf zones), which typically have little in situ primary production. We also examime the spatial scaling of the influence of these processes across the broader seascape and landscape, and identify key gaps in our knowledge to guide future research directions and priorities. Globally, large quantities of detrital kelp and seagrass can flow into sandy beach ecosystems, where microbial decomposers and animals remineralise and consume the imported organic matter. The supply and retention of wrack are influenced by the oceanographic processes that transport it, the geomorphology and landscape context of the recipient beaches, and the condition, life history and morphological characteristics of the taxa that are the ultimate source of wrack. When retained in beach ecosystems, wrack often creates hotspots of microbial metabolism, secondary productivity, biodiversity, and nutrient remineralization. Nutrients are produced during wrack break-down, and these can return to coastal waters in surface flows (swash) and the aquifier discharging into the subtidal surf. Beach-cast kelp often plays a key trophic role, being an abundant and preferred food source for mobile, semi-aquatic invertebrates that channel imported algal matter to predatory invertebrates, fish, and birds. The role of beach-cast marine carrion is likely to be underestimated, as it can be consumed rapidly by highly mobile scavengers (e.g. foxes, coyotes, raptors, vultures). These consumers become important vectors in transferring marine productivity inland, thereby linking marine and terrestrial ecosystems. Whilst deposits of organic matter on sandy beach ecosystems underpin a range of ecosystem functions and services, these can be at variance with aesthetic perceptions resulting in widespread activities, such ‘beach cleaning and grooming’. This practice diminishes the energetic base of food webs, intertidal fauna, and biodiversity. Global declines in seagrass beds and kelp forests (linked to global warming) are predicted to cause substantial reductions in the amounts of marine organic matter reaching many beach ecosystems, likely causing flow-on effects on food webs and biodiversity. Similarly, future sea-level rise and stormier seas are likely to profoundly alter the physical attributes of beaches, which in turn can change the rates at which beaches retain and process the influxes of wrack and animal carcasses. Conservation of the multi-faceted ecosystem services that sandy beaches provide will increasingly need to encompass a greater societal appreciation and the safeguarding of ecological functions reliant on beach-cast organic matter on innumerable ocean shores worldwide.
