To fish or to dive?: A case study of fisher and diver perceptions of coral reef management

This week is #BlackInMarineScience week and here at Oceanbites we’re featuring the work of Black scientists all week long! Today’s post is featuring work done by Dr. Ayana Johnson on coral reefs and how best to manage them under changing ocean conditions. Read on to learn a bit about Dr. Johnson and her research. Diana […]

Of rain and reefs: Future downpours in French Polynesia could change the coast

In many ways, coral reefs are the Goldilocks of the ocean. But as climate change shifts conditions near many of the planet’s reefs, finding “just right” may be increasingly difficult. Researchers at UCLA set out to explore how one expected outcome of climate change, extreme rainfall events, may impact coral reefs in the future. Kristin […]

Predicting the future of coral reefs is complicated by human impacts

Coral reefs are often referred to as the “rainforests of the sea” for hosting a great diversity of life, but this incredibly productive ecosystem is seriously threatened by human activities. To better evaluate changes happening in the reef communities and develop strategies to mitigate damages done to coral reefs, understanding how human activities affect our […]

Ocean acidification: The lesser known CO2 Problem

You have heard about global warming due to increased atmospheric carbon dioxide but did you know that it also affects oceans globally! Read on to learn more. Tejashree ModakCurrently, I am a postdoctoral research fellow in URI.  Broadly, I study response of marine species to various stressors such as disease and environmental factors. My research […]

Volcanoes and Climate: A Not-So-Explosive Relationship

Reviewing: Dee, Sylvia G., et al. “No consistent ENSO response to volcanic forcing over the last millennium.” Science 367.6485 (2020): 1477-1481. Introduction When you hear the term El Nino, you may recall that it has something to do with rainfall in the Southwest or droughts in Australia but did you know that the El Nino […]

A Fishy Ally to Help Coral Reefs

What if we had something on the inside to help us fight climate change’s impacts on coral reefs? A helpful ally which could increase coral bleaching tolerance and boost post-bleaching recovery in the field and in real time? As it turns out, we do: damselfish. Rishya NarayananRishya is a multimedia science communicator with an MS […]

In an Uncertain Future, How Might Corals Survive?

Scleractinian corals form the framework for reef ecosystems but are increasingly threatened. By looking at the coral fossil record, scientists are beginning to understand how corals have survived in the past, and what will happen to them in the future. Elena GadoutsisI have always been happiest in nature – exploring forests, traveling to the ocean, […]

Renewed hope for reef-building corals to combat climate change.

If you have ever had a chance to snorkel in a reef, you would agree that it is an unforgettable experience. Its special mainly because of the colorful corals and the diverse life forms they support. But corals around the world are being hit hard from effects of warming ocean temperatures and ocean acidification. Corals […]

Slowing a Thorny Invasion – Managing for COTS with DNA

Crown-of-Thorns Starfish are a natural scourge on coral reefs… or are they? The cycle of outbreaks is cruel, since it tends to focus on areas that have been spared bleaching. What eats a COTS anyway? Can we harness natural predators to minimize the impacts of these coral-eaters? One team is trying.

Climate-driven events leave an imprint on corals in the Great Barrier Reef

In this re-post, we discuss the ecological memory of corals from bleaching events that occurred back-to-back in 2016 and 2017. With this pattern repeating itself in 2020, has mass bleaching become a near-annual event? Nyla HusainI’m a PhD student at the University of Rhode Island’s Graduate School of Oceanography. I use a small-scale computer model […]

Blue Coral with a Not-So-Blue Future

Before this genetics study, we only knew of one extant octocoral species producing a massive skeleton. Not only does Iguchi’s study reveal speciation in blue coral, but it also suggests potential thermal resilience. Constance SartorConstance is a graduate student at the University of Guam studying coral genetics. She also paints murals integrating art and science […]

Of Wildfires and Oceans

Wildfires are all over the news, from California to Australia, but do these terrestrial events have any impact on ocean ecosystems? Is it possible that wildfires can cause massive coral die-off across reefs? A research paper from 2003 provides some insight into these questions, and points to a need for more studies on the links […]

Ensuring that coral reefs sound like home

What does a coral reef sound like? The answer is more important than you might think. By playing the sounds of a healthy reef over a loudspeaker, scientists were able to attract a variety of baby fish to settle on a degraded reef, results which show how acoustic interventions are a tool that can be […]

3D Printing Can Help Coral Environments, Here’s How.

In the face of mass bleaching and other anthropogenic stressors, researchers and scientists alike have been working on ways to both bolster coral reef growth and study coral reef environments without disrupting them – and 3D printing coral structures has been one technique used to do so. However, before the use of 3D models in […]

Can Coral Reefs Strangled By Algae Recover?

“Experimental support for alternative attractors on coral reefs”, Russell J. Schmitt, Sally J. Holbrook, Samantha L. Davis, Andrew J.Brooks, Thomas C. Adam, Proceedings of the National Academy of Sciences Mar 2019, 116 (10) 4372-4381; DOI: 10.1073/pnas.1812412116   This article was reposted from March 2019.   Why Too Much Algae Hurts Coral Reefs Coral wages a constant battle against algae for space and dominance. On a healthy coral reef, it’s a battle […]

Lost in the sound: coral planulae habitat selection affected by boat noise

It can be hard to cut through the noises that surround us and focus on the task in front of us, right? This may not just be a human problem. Noise pollution may be another way human activity is negatively affecting corals. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and […]

The Coral Dilemma: Is Hybridization the Key?

Coral: a mineral, plant, and animal all in one (oh my!) Unfortunately, coral is in danger- and the many reefs which support a wide variety of organisms (including humans) are rapidly dying. Does interspecific hybridization hold the key to our coral dilemma? Rishya NarayananRishya is a multimedia science communicator with an MS in Media Advocacy from […]

Small MPAs: the new all-you-can-eat buffets?

Marine Protected Areas (MPAs) are a popular conservation tool and are in many situations very effective. Unfortunately, as with many plans, there may be some unintended consequences, as seen in the case of small MPAs in Fiji, where they appear to have attracted corallivorous crown-of-thorns sea stars (Acanthaster spp.). Find out more in today’s oceanbites! […]
