Flexibility in algal endosymbioses shapes growth in reef corals.
The relation between corals and their algal endosymbionts has been a key to the success of scleractinian (stony) corals as modern reef-builders, but little is known about early stages in the establishment of the symbiosis. Here, we show that initial uptake of zooxanthellae by juvenile corals during natural infection is nonspecific (a potentially adaptive trait); the association is flexible and ...
متن کاملWhy trap light?
In 1865 James Clerk Maxwell showed how light propagates as electromagnetic waves. In 1984 it was realized that light can also be trapped1. My journey into this subject began as a PhD student at Harvard University, focusing on the possibility to trap or localize any classical wave in a suitable material2. This was not one of the ‘big questions of science’ at the time, but my supervisor Michael J...
متن کاملShedding (blue) light on algal gene expression.
L ight in the blue region of the spectrum [blue light (BL), 400– 480 nm] is an ubiquitous environmental signal. BL can penetrate marine water to a depth greater than all other wavelengths, up to the limits of the photic zone ( 1,500 m depth) and may be linked to the evolution of photosynthesis (1). BL is also potentially dangerous because it is readily absorbed by intracellular photosensitizers...
متن کاملAllelopathic interactions between the brown algal genus Lobophora (Dictyotales, Phaeophyceae) and scleractinian corals
Allelopathy has been recently suggested as a mechanism by which macroalgae may outcompete corals in damaged reefs. Members of the brown algal genus Lobophora are commonly observed in close contact with scleractinian corals and have been considered responsible for negative effects of macroalgae to scleractinian corals. Recent field assays have suggested the potential role of chemical mediators i...
متن کاملThe effects of elevated seawater temperatures on Caribbean gorgonian corals and their algal symbionts, Symbiodinium spp.
Global climate change not only leads to elevated seawater temperatures but also to episodic anomalously high or low temperatures lasting for several hours to days. Scleractinian corals are detrimentally affected by thermal fluctuations, which often lead to an uncoupling of their mutualism with Symbiodinium spp. (coral bleaching) and potentially coral death. Consequently, on many Caribbean reefs...
