Coral reefs are a vital source of aquatic habitat, but they are declining at an alarming rate as a result of global change and human pressure. A detailed mapping of coral reef habitat with high spatial and time resolutions has become a critical step in monitoring their health and evolution. To account for the new surge in published research on coral reel mapping, we're particularly interested in the papers published between 2018 and 2020. The best photos for benthic habitat mapping can be found on satellites with the highest spatial resolution, according to We emphasize that the best images for benthic habitat mapping are obtained from satellites with the highest spatial resolution.

Coral reefs need proper monitoring and protection efforts. For the proper administration of the ecosystem, an ecosystem service model is required. This report looked at the correlation between ecosystem services administration in international, national, and local environmental legislation, as well as the coral reef ecosystem. The researcher found a positive correlation between the ecosystem services administration in the international, national, and local environmental regulations, as well as policy addressing the sustainable development of the coral reef ecosystem.

Deep water ports are by definition, ocean-based coastal buildings that encourage ship traffic and disturbance. Port Everglades Inlet, South Florida's biggest cargo port for over two million residents, is located close to coral reefs, dwindling mangroves, and recreational beaches. The microbial communities of PEI and adjacent reef sediments were characterized as indicators of change in these fragile ecosystems by dredging and assessing anthropogenic influence on these fragile ecosystems by sequencing the V4 region of 16S rRNA ahead of a large-scale port deepening event. PEI sediments and adjacent coral reef sediments were collected for two years in a row from PEI sediments and adjacent coral reef sediments from two years, 2020 and 2021. In spite of their proximity and tidal links with the PEI, reef, and PEI sediment microbial populations, the microbial communities were still distinct.

A coral reef is a type of reef that is found in the warm shallow sea and is widely distributed. Divers are tied together by chemical compounds and live in families for generations. Yellow algae is an algae plant that absorbs sunlight and provides corals with nutrients by photosynthesis. In addition to the immediate effects of global warming on the marine ecological climate, oxybenzone in sunscreen and other skin care products has been found in marine and freshwater entertainment areas, and oxybenzone in sunscreen and other skin care products has been found in aquatic animals and degrade into hazardous substances.

To avoid fish species loss, coral reefs must have a greater understanding of large-scale patterns and processes, but it does need new monitoring techniques. We use environmental DNA geobarcoding to reconstruct well-known patterns of fish species on coral reefs and uncover hidden patterns in these highly diverse and threatened ecosystems. We collected 226 environmental DNA seawater samples from 100 stations in five tropical areas and compared them to 2047 underwater visual censuses from the Reef Life Survey in 1224 stations.

One of the coastal ecosystems that play a key role in cultural and economic growth on Weh Island, Aceh, Indonesia, is the coral reef ecosystem. This study aims to investigate coral reef distribution in Weh Island in order to promote marine tourism. The coral reefs on Weh Island in 2020 measured 13,136,000 ha on the island of Weh Island, according to the findings. Therefore, the creation of marine tourism must include tourism zones to ensure the coral reef ecosystems' sustainability.

Soft corals of the genus Clavularia are both difficult and difficult to distinguish morphological characteristics, making them rather difficult to identify. Specimens of Clavularia inflata were collected from eleven research sites around the Indonesian archipelago and compared among locations, based on their sclerite characteristics. C. inflata specimens from Kepulauan Seribu's largest pinnule, calyx, and stlon sclerites were found in the largest C. inflata samples compared to other locales. Morphometric tests of C. inflata revealed the following: Compared to other locations. For specimens from Maluku Tenggara Barat, the maximum mean size of crown sclerites was found. In conclusion, there were variations in the size of sclerites throughout the eleven study sites, with several sites forming a group of similar sclerite dimensions at several locations.

This research aims to determine the distribution of coral reef ecosystems and test landsat 8 oli imagery accuracy in mapping coral reef ecosystems. Key words: Landsat 8 is a type of coral reef ecosystem class in Pulau Weh Sabang, according to the results, a healthy coral reef ecosystem class of 277. 38 hectares and a medium condition coral reef ecosystem class with an area of 710. 01 Ha.

Chromadoridae Filipjev, 1917, according to a report involving experiments on a natural Brazilian coral reef with the intention of finding the effects that could be caused by an increase in sea level on benthic fauna, Chromadorida's most abundant and diverse family of Nematoda. Chromadora Bastian, 1865 was the most abundant and diverse genus, represented by three species, C. serrambi sp. C. pernambucana sp. , nov. , C. pernambucana sp. , C. pernambucana sp. , nov. , C. pernambucana sp. , nov. , C. pernambucana sp. Chromadora serrambi sp. Sep vs. Chromadora serrambi sp. nov. is the only Chromadora species in which pre-cloacal supplements are absent. Chromadora macrolaimoides is very similar to specimens that have been described previously.
