Corals in Palau did not suffer mass bleaching during the 2017 marine heatwave despite levels of heat stress and light intensity that were broadly equivalent to the conditions that led to mass bleaching in 1998 and 2010 at the same reefs.

Pacific coral reef shows increase in climate resistance

The ability of coral reefs to adapt to changing ocean temperatures is a pressing question in marine biology.  

Coral reefs are currently experiencing significant declines. These declines are primarily due to marine heatwaves, which lead to widespread coral bleaching and mortality. Understanding how coral communities can adapt to increasingly severe and frequent marine heatwaves is crucial for their survival in the face of climate change.

There are two subspecies of West Indian manatees: the Antillean manatee (Trichechus manatus manatus) and the Florida manatee (Trichechus manatus latirostris), the latter of which is shown above. In the United States, manatees are protected under the Marine Mammal Protection Act, which prohibits the take (i.e., harass, hunt, capture or kill) of all marine mammals.

Manatees up for protection

Federal wildlife authorities are re-evaluating the classification of manatees, a move prompted by mounting issues, most notably the devastating loss of seagrass, a critical food source for these gentle marine creatures.

A Long-Overdue Review

The U.S. Fish and Wildlife Service recently announced its intention to revisit the categorization of manatees, contemplating a return from “threatened” to “endangered.” This potential reversal would overturn the 2017 decision to reclassify manatees.

Pemuteran Sea Turtle Hatchery

A sea turtle hatchery in Pemuteran, Indonesia, established by Reef Seen Divers’ Resort founder, Chris Brown, has provided a sanctuary for endangered baby turtles to hatch and grow large enough to be released into the sea with better chances of survival. Claudia Weber-Gebert has the story.
