Chilika Lake, Asia’s largest brackish water lagoon situated on the East coast of India is separated from Bay of Bengal by sand bars and connected with the sea by a series of tidal inlets. The inlets are maintained by discharges of inflowing streams during monsoon and by tides and ebb tides during non-monsoon. Imbalance in ingress and egress of sediment due to their continuous exchange between s...

A 5 yr spring and summer survey (July 2000 to May 2004) of the elasmobranch fauna of Glover’s Reef Marine Reserve, Belize, documents the use of this oceanic atoll by at least 12 elasmobranch species, including early life-stages of nurse sharks Ginglymostoma cirratum, Caribbean reef sharks Carcharhinus perezi, lemon sharks Negaprion brevirostris, and southern stingrays Dasyatis americana. Elasmo...

Sponges are often as abundant as corals on tropical coral reefs and many species are symbiotic with algae. These associations may contribute significantly to reef primary productivity. This paper describes the first study ever made of the population biology of any of the known associations between sponges and macroalgae. Populations of the symbiotic association between the sponge, Haliclona cym...

Emissions of atmospheric ammonia–nitrogen (NH3-N, where NH3-N 1⁄4 (14/17)NH3) and hydrogen sulfide (H2S) from a commercial anaerobic swine waste treatment lagoon (17,150m at normal liquid level) were measured over a 1-year period. Continuous simultaneous measurements were made at the lagoon using a dynamic flow-through chamber system for 1 week during four seasons, October–November 2004 (fall),...

The coastal plain of the Rio Grande do Sul state (RS) in southern Brazil, has an enormous lagoon complex in its southern portion formed by Patos Lagoon, Mirim Lagoon, Mangueira Lagoon and several other smaller lakes. This system was originated from successive transgression and regression cycles, which took place since the upper Pleistocene (Vilwoock, 1984). Patos Lagoon is a huge chocked lagoon...

Participation as a tool has been applied as a social learning process and communication platform to create awareness among stakeholders in the context of resource utilisation. The application of participatory processes to aquatic ecosystem management is attracting a growing body of literature. However, the application of participation as a tool for sustainable management of coastal lagoon ecosy...
