  • Some skates (a cross between a shark and a ray) are known to lay their eggs on bubblegum corals ( Paragorgia sp. (noaa.gov)
  • For two to four nights, each individual coral polyp on a colony releases a bundle of eggs and sperm into the water column. (smithsonianmag.com)
  • This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. (noaa.gov)
  • But in the past 30 years, a staggering 80 percent of corals have been destroyed in the Caribbean alone. (smithsonianmag.com)
  • Saving Coral…Through Sperm Banks? (smithsonianmag.com)
  • She has created the first frozen repositories of coral sperm and embryonic cells. (smithsonianmag.com)
  • The "sperm banks," with samples from elkhorn coral and Hawaiian mushroom coral, are an insurance policy of sorts, in that they could be tapped one, 50 or even 1,000 years from now to restore and add genetic diversity to dying populations. (smithsonianmag.com)
  • Mary Hagedorn has created the first frozen repositories of coral sperm. (smithsonianmag.com)
  • The "sperm banks," with samples from elkhorn coral, shown here, and Hawaiian mushroom coral, are an insurance policy of sorts. (smithsonianmag.com)
  • When the corals are beginning to "set," meaning they are becoming pimpled with egg-sperm bundles ready to be released, Hagedorn and her team of divers put fine, custom-fit nets over individual corals. (smithsonianmag.com)
  • Coral Reef Ecosystem Program standard operating procedures: data collection for Rapid Ecological Assessment fish surveys. (noaa.gov)
  • The key indicators used to identify and monitor climate-driven trends include 1) thermal stress caused by changes in sea temperature, 2) ocean acidification resulting from changes in carbonate chemistry, and 3) ecological impacts by collecting data on coral growth rates, erosion, and community structure to understand the impacts of thermal stress and ocean acidification on the ecosystem.

  • AbstractSponges occur across diverse marine biomes and host internal microbial communities that can provide critical ecological functions. (researchgate.net)
  • Swimmers and people using small water craft damage fragile corals. (guampedia.com)
  • With the BW-1 and FL-1 dive lights you can use fluorescence to search for coral recruits and juveniles both at night and in the daytime. (globalcoral.org)
  • Fluorescence census techniques for the early detection of coral recruits. (globalcoral.org)
  • Fluorescence census techniques for coral recruits. (globalcoral.org)
  • No. Not all coral recruits fluoresce, and some that do fluoresce do not glow brightly enough to be found easily. (globalcoral.org)
  • The nursery cultures both sexual recruits and fragmented corals for rehabilitation and replanting. (guampedia.com)
  • He continues: "Key to coral reef survival is that the remaining individuals produce enough offspring that can recruit on damaged reefs and help them to recover. (southampton.ac.uk)
  • Various coral restoration techniques are being tested and developed here on Guam to help reefs recover. (guampedia.com)
  • Coral restoration is similar to planting trees to help forests recover, in that different methods are used to reproduce, grow and plant specific types of coral. (guampedia.com)
  • Coral secrets Images of kissing corals and seafloor turf wars have been captured for the first time by scientists using a revolutionary new underwater microscope. (abc.net.au)
  • Furthermore, the blue coral possesses homologs of biomineralization genes found in other corals and may use a biomineralization strategy similar to that of scleractinians to build its massive aragonite skeleton. (nature.com)
  • Analysis of the blue coral transcriptome revealed enrichment of genes involved in stress response, including heat-shock proteins and antioxidants, as well as genes participating in signal transduction and stimulus response. (nature.com)
