The identification of coral recruits has been problematic due to a lack of definitive morphological characters being available for higher taxonomic resolution. In this study, we tested whether fluorescent detection of coral recruits used in combinations of different DNA-barcoding markers (cytochrome oxidase I gene [COI], open reading frame [ORF], and nuclear Pax-C intron [PaxC]) could be useful...

Coral reefs are declining worldwide due to multiple factors including rising sea surface temperature, ocean acidification, and disease outbreaks. Over the last 30 years, White Band Disease (WBD) alone has killed up to 95% of the Caribbean`s dominant shallow-water corals--the staghorn coral Acropora cervicornis and the elkhorn coral A. palmata. Both corals are now listed on the US Endangered Spe...

Reef-building corals produce planktonic planula larvae that must select an appropriate habitat to settle and spend the rest of their life, a behaviour that plays a critical role in survival. Here, we report that larvae obtained from a deep-water population of Pseudodiploria strigosa settled more readily under blue light and in the dark, which aligns well with the light field characteristics of ...

Climate change scenarios predict stronger and more frequent hurricanes. We studied survival patterns of Acropora palmata during the hyper-active 2005 Atlantic Hurricane Season [AHS] to assess future effects of routinely elevated storm seasons. Before the start of the 2005 AHS, 105 colonies on three survey reefs in the EPA/NOAA Coral Reef Monitoring Project were marked and tracked through 2007. ...

White band disease type I (WBD I) has been a major cause of the dramatic decline of Acroporid coral populations throughout the Caribbean during the last two decades, yet the aetiological agent of this disease is unknown. In this study, the bacterial communities associated with both healthy and diseased Acropora species were compared by 16S rDNA analyses. The bacterial communities of both health...

BACKGROUND Miniature inverted-repeat transposable elements (MITEs), which are common in eukaryotic genomes, are small non-coding elements that transpose by utilizing transposases encoded by autonomous transposons. Recent genome-wide analyses and cross-mobilization assays have greatly improved our knowledge on MITE proliferation, however, specific mechanisms for the origin and evolution of MITEs...

Mangubhai & Harrison (2008; Mar Ecol Prog Ser 360:85–96) documented spawning patterns in an equatorial assemblage of Acropora spp. in Kenya over a 2 yr period. They concluded that reproductive seasons are more protracted at low latitudes and that ‘mass spawning’ does not occur in equatorial regions, due to a breakdown in spawning synchrony among species. However, this interpretation hinges on t...

The impacts of warming seas on the frequency and severity of bleaching events are well documented, but the potential for different Symbiodinium types to enhance the physiological tolerance of reef corals is not well understood. Here we compare the functionality and physiological properties of juvenile corals when experimentally infected with one of two homologous Symbiodinium types and exposed ...
