PortMiami dredging has killed half a million corals, as the study by Miami Waterkeeper shows

Coral reefs are more than just unique, irreplaceable ecosystems full of natural wonders of the earth: studies show they also act as natural storm surge barriers that help break up gigantic waves before they roll over cities like Miami. Florida's reefs are worth $ 1.6 billion worth of property, according to a recent study. Meanwhile, the cruise industry is sending …

After bleaching, corals of the Great Barrier Reef do not jump back quickly

Enlarge / Bleached Coral in March 2017. The Australian Great Barrier Reef was hit hard by warm seawater in 2016 and 2017. Disasters in the background were filled with widespread coral extinctions. During the heat of ocean waves, corals must drive out the single-celled symbiots that are photosynthesized in them. The corals thus get a pale white color – a …

Research says that changing temperature can affect corals

Research says changing temperature can affect coral (fig. Image) Scientists carried out a new research showing that rising temperatures reduce stress on coral reefs of 30-150 meters ( mesophoten zone) from the sea surface. Previously, researchers used sea-surface temperature data collected by satellites to predict the temperature-related stress on corals. New research shows that the sea surface temperature alone could …

Various symbionts of reef corals have been around since 'Age of Dinosaurs & # 39; persevered

Corals, such as the branched acropora found here, are animals that form massive reef racks and form the basis of coral reef ecosystems. These corals ultimately depend on microalgae symbionts that absorb the sun's light and convert it into nutrients for the growth and survival of the host corals. Credits: Tobin T. Smith Coral-algae partnerships have gone through many climate …
