Histological observations in the Hawaiian reef coral, Porites compressa, affected by Porites bleaching with tissue loss.
The scleractinian finger coral Porites compressa is affected by the coral disease Porites bleaching with tissue loss (PBTL). This disease initially manifests as bleaching of the coenenchyme (tissue between polyps) while the polyps remain brown with eventual tissue loss and subsequent algal overgrowth of the bare skeleton. Histopathological investigation showed a loss of symbiont and melanin-con...
متن کاملSurviving Coral Bleaching Events: Porites Growth Anomalies on the Great Barrier Reef
Mass coral bleaching affected large parts of the Great Barrier Reef (GBR) in 1998 and 2002. In this study, we assessed if signatures of these major thermal stress events were recorded in the growth characteristics of massive Porites colonies. In 2005 a suite of short (<50 cm) cores were collected from apparently healthy, surviving Porites colonies, from reefs in the central GBR (18-19°S) that h...
متن کاملNOTE Skeletal isotopic record of a Porites coral during the 1998 mass bleaching event
Based on skeletal oxygen and carbon isotope analyses, we found a remarkable decrease in skeletal linear extension rate of a Porites colony during the bleaching event of 1998 around the Ryukyu Islands. Water temperature in the summer of 1998 was recorded as the highest for at least last 50 years in the region. This colony, growing in a channel of fringing reef in Ishigaki Island, has experienced...
متن کاملMesophotic Coral Reef Ecosystems of the US Virgin Islands and the Caribbean
Mesophotic coral reefs (MPR) are some of the least studied and most poorly understood light dependant coral habitats in the world. These reefs form in deep, dimly lit waters around the globe in what has been called the “Twilight Zone”. Available data for the Caribbean and extrapolation from bathymetric data suggest that these environments are extensive between 30 and 100 m. These systems are sp...
متن کاملPorites superfusa mortality and recovery from a bleaching event at Palmyra Atoll, USA
BACKGROUND The demography of a coral colony is not a binary trajectory of life and death. Based on the flexibility afforded by colonial organization, most reef-building corals employ a variety of dynamic survival strategies, including growth and shrinkage. The demographic flexibility affects coral size, shape and reproductive output, among other factors. It is thus critical to quantify the rela...
