Incipient speciation across a depth gradient in a scleractinian coral?
A few marine cases have demonstrated morphological and genetic divergence in the absence of spatial barriers to gene flow, suggesting that the initial phase of speciation is possible without geographic isolation. In the Bocas del Toro Archipelago of the Atlantic Coast of Panama, we found two morphotypes of the scleractinian coral Favia fragum with opposing depth distributions. One morphotype fi...
متن کاملInnate immune responses of a scleractinian coral to vibriosis.
Scleractinian corals are the most basal eumetazoan taxon and provide the biological and physical framework for coral reefs, which are among the most diverse of all ecosystems. Over the past three decades and coincident with climate change, these phototrophic symbiotic organisms have been subject to increasingly frequent and severe diseases, which are now geographically widespread and a major th...
متن کاملMetamorphosis of a scleractinian coral in response to microbial biofilms.
Microorganisms have been reported to induce settlement and metamorphosis in a wide range of marine invertebrate species. However, the primary cue reported for metamorphosis of coral larvae is calcareous coralline algae (CCA). Herein we report the community structure of developing coral reef biofilms and the potential role they play in triggering the metamorphosis of a scleractinian coral. Two-w...
متن کاملPocillopora aliciae: a new species of scleractinian coral (Scleractinia, Pocilloporidae) from subtropical Eastern Australia.
Lack of morphological features of diagnostic value and high levels of environmental phenotypic plasticity obscure species boundaries for most taxa in the genus Pocillopora Lamarck, 1816 and complicate the definition of taxonomically distinct units. Species of the genus are colonial, generally ramose, rarely massive or encrusting and mostly hermatypic; corallite arrangement is plocoid, septa are...
متن کاملHigh phosphate uptake requirements of the scleractinian coral Stylophora pistillata.
Several untested aspects of the regulation of inorganic nutrient uptake were examined using nutrient depletion experiments with the symbiotic coral Stylophora pistillata. The total inhibition of phosphate uptake in artificial seawater lacking sodium indicates the involvement of a sodium/phosphate symporter for the uptake of phosphate across host membranes. Addition of ammonium or nitrate (up to...
