Seagrass health condition is monitored periodically since 2018 in Indonesia, and the most recent data reported here is from the monitoring in 2021. Assessment on health condition of seagrass ecosystem is based on “Seagrass Ecological Quality Index (SEQI)”. In 2021, Indonesian seagrass shows SEQI value of 0.66, meaning that the seagrass ecosystem in...

Seagrass meadows, like other tropical coastal ecosystems, are highly productive and sustain millions of people worldwide. However, the factors that govern the use of seagrass as a fishing habitat over other habitats are largely unknown, especially at the household scale. Using socioeconomic factors from 147 villages across four countries within the...
Article
The extent of seagrass areas and their associated ecosystem functions and services have been declining due to many factors. Seagrass restoration is important to mitigate such declines. Seagrass restoration using seeds can be a viable method due to the high seed availability of some seagrass species and could enhance seagrass resilience to climate c...

Indonesia’s seagrass habitats play an important role in the fight against climate change since they store a significant portion of the world’s blue carbon. Despite progress in conservation efforts and increasing number of Indonesia’s marine protected areas (MPAs), these habitats are generally still under multitude of pressures leading to declining...

Ecological regime shifts in the marine realm have been recorded from a variety of systems and locations around the world. Coral reefs have been especially affected, with their benthic habitat changing from a dominance of stony corals to a dominance of other organisms such as fleshy algae. To detect changes in the benthic habitat of coral reefs, sim...

Members of the family Symbiodiniaceae form symbiotic relationships with several metazoan groups on coral reefs, most notably scleractinian corals. However, despite their importance to the health of coral reefs, their relationship with other host organisms such as bioeroding sponges (Clionaidae) is still relatively understudied. In this study we inv...
