Zooxanthellae ultrastructure affected in bleached corals
Most reef-building corals are hermatypic: they harbour endosymbiotic algae of the dinoflagellates group (generally called zooxanthellae, genus Symbiodinium), within vacuoles in the gastroderm cells. Bleaching, loss of colour due to loss of these symbiotic algae and/or their photosynthetic pigments, on a large scale, appears to increase by intensity and geographic extent, certainly related to in...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولInteractions between Corals and their Symbiotic Algae
Interactions between Corals and their Symbiotic Algae Gisèle Muller-Parker and Christopher F. D'Elia The mutualistic relationship between corals and their algal endosymbionts is a key factor in the evolutionary success of hermatypic (reef building) corals. Corals that harbor endosymbiotic algae exhibit faster rates of calcification, photoautotrophy and many other attributes that are believed to...
متن کاملChanges in zooxanthellae density, morphology, and mitotic index in hermatypic corals and anemones exposed to cyanide.
Sodium cyanide (NaCN) is widely used for the capture of reef fish throughout Southeast Asia and causes extensive fish mortality, but the effect of NaCN on reef corals remains debated. To document the impact of cyanide exposure on corals, the species Acropora millepora, Goniopora sp., Favites abdita, Trachyphyllia geoffrio, Plerogyra sp., Heliofungia actinformis, Euphyllia divisa, and Scarophyto...
متن کاملIs photoinhibition of zooxanthellae photosynthesis the primary cause of thermal bleaching in corals?
The bleaching of corals in response to increases in temperature has resulted in significant coral reef degradation in many tropical marine ecosystems. This bleaching has frequently been attributed to photoinhibition of photosynthetic electron transport and the consequent photodamage to photosystem II (PSII) and the production of damaging reactive oxygen species (ROS) in the zooxanthellae (Symbi...
