Sponges are important components of reef communities worldwide, fulfilling a number of important functional roles. Habitat degradation caused by the loss of hard corals has the potential to cause increases in sponge abundance and percentage cover as they gain access to resources such as space and food. In this study we compared sponge densities and percentage cover at sites with varying hard co...

Despite the fact that national parks and other protected areas are mostly adopting the sustainable development process, it was found that sustainability has yet to be perceived pragmatically in these areas. Due to its process, this paper presents a monitoring framework approach to develop and implement indicators for sustainable tourism. To illustrate the application of the framework, a set of ...
