A Coral Reef has an important role in keeping a balanced ecosystem the ocean. This research aims to develop mobile application track and classify identify Reefs with presentation of information names species, type classification coral (hard or soft coral), accuracy, area distribution that been recorded before certain areas. research, utilized Flutter for deploying application, Deep Learning Tra...

Corals perform simultaneous mass spawning around the full moon. Most Acropora species release gamete bundles, which are a complex of eggs and sperm, into the seawater. Then, gamete bundles are separated into eggs and sperm. Eggs are fertilized when sperm and eggs come in contact with each other. However, it is still unclear how sperm meet the eggs of the same species in the presence of many egg...

Specimens for the study on coral spawning of three species were collected at two sites in Nha Trang bay, South Vietnam, 2014, 2015, 2016, 2018 and 2019. The determination seasons was based observations gonadogenesis development A. florida robusta variation egg average sizes these hyacinthus. Data analysis comparative discussions allow us to assume that 3 Acropora exhibited single cycle annually...

Abstract Zooplanktivory is an important source of nutrients in corals, providing up to 35% daily metabolic energy requirements some species. However, little known about coral zooplanktivory shortly after larval settlement and metamorphosis. In most species it unclear if, when under which conditions newly settled polyps are able capture ingest prey. This remains a critical knowledge gap, as coul...

Far more intimate knowledge of scleractinian coral biology is essential in order to understand how diverse coral-symbiont endosymbioses have been established. In particular, molecular and cellular mechanisms enabling the establishment and maintenance of obligate endosymbiosis with photosynthetic dinoflagellates require further clarification. By extension, such understanding may also shed light ...

Abstract Damselfish of the genus Stegastes inhabit territories and cultivate algal gardens on branching corals Acropora , aggressively protecting their from other fish preventing predation upon within territory. This behaviour has important ecological impacts could also be useful in reducing outplanted during reef restoration efforts. However, degree protection predators may depend ability spp....

The inshore reefs of the Great Barrier Reef (GBR) have undergone significant declines in water quality following European settlement (approx. 1870 AD). However, direct evidence of impacts on coral assemblages is limited by a lack of historical baselines prior to the onset of modern monitoring programmes in the early 1980s. Through palaeoecological reconstructions, we report a previously undocum...
