Coral Reef Restoration Through Human-Assisted Evolution

Coral reefs populations are declining. Is it possible that we could help restore coral reefs by speeding up their evolutionary processes? Researchers propose new management strategies for aiding reef restoration by accelerating the natural processes of evolution. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology […]

Corals consume microplastics! Talk about an unhealthy diet!

The dangerous diet fad among marine organisms is spreading! New study shows corals consume microplastics. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing to the management of an estuary. I am fascinated by the wonders of nature, […]

Macrobioerosion rates and what they mean for reefs

Today macrobioerosion is a good thing that provides cement for the foundation of reef systems. So more macrobioerosion could mean more reefs, right? No! Perhaps too much of a good thing could have dire consequences for the future of the calcium carbonate budget. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a […]

Is a coral’s color all for show?

Two of the exact same corals, sitting right next to each other, often appear to be different based on their colors. Why is this? Scientists have shown that the answer involves intriguing genetics. The more genes a coral activates, the greater their strength of color. Valeska UphamFor my fisheries and aquatic science PhD I am […]

Don’t let your guard down: a cautionary tale from reef fish in degraded habitat.

Reef fish on degraded reef are somewhat like misguided slasher flick protagonists that ignore all warning cues and are therefore less likely to survive. Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing to the management of an […]

Can a complex model hold the fate of the crown-of-thorns starfish?

Not all starfish are cute! The crown-of-thorns starfish has been eating all the coral on the Great Barrier Reef! Researchers set out to build a model in hopes of demonstrating the trophic interactions between this dangerous starfish and its prey, the coral. Valeska UphamFor my fisheries and aquatic science PhD I am working on how […]

The Great Barrier Reef is worth $15 billion – $20 billion AUS a year: A quick lesson in ecosystem economics

When discussing the value of an ecosystem, tensions run high. Some people evaluate ecosystems with heavy emphasis on non-use values, like aesthetics and spiritual appreciation. Other people value ecosystems based on things like natural resource availability and the potential for direct monetary revenue. It is difficult to assess the relative importance (or value) of these […]

Get crabby! A coral’s guide to self-defense

Crabs in the genus Trapezia are not only good housekeepers, clearing sediment off host corals, but they are also effective defenders. While just the presence of guard crabs can increase the chance of coral survival, are different species more effective than others? Read more to find out! Megan ChenI graduated with a Masters of Coastal […]

Deep Blue Reads: The Reef: A Passionate History, by Iain McCalman

It’s often easy to think of science outside of its social and historical contexts, as something pure, empirical, and incorruptible. But each drop of knowledge inevitably depends on what was uncovered and refined in the decades and centuries before it, as well as how it fits with the social and cultural opinions of its time. […]

Measuring “Roundup” in the Great Barrier Reef

Scientists estimated the degradation time for glyphosate, an herbicide in “Roundup”, in the Great Barrrier Reef. This is the first study of the persistence of glyphosate in seawater. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses fisheries and climate change in […]

Deep Blue Reads: The Sixth Extinction, by Elizabeth Kolbert

As a novelist writing about oceanography, I spend a decent amount of time parsing scientific studies. Over the past several years my vocabulary has expanded to include terms like band saturation, turbidity currents, and foraminifera—phrases and words that had not existed in my wildest dreams when I first started writing. I’ve relied on studies and […]

One fish, two fish, red fish… glow fish?

Biofluorescence of coral is well studied, but in this paper, Sparks et al. aimed to investigate the little known details regarding the impact of biofluorescence on the other creatures that thrive in coral reef habitats, specifically the 8,000+ species of fishes. What they found was shocking. Not only is biofluorescence widespread throughout the tree of […]

Coral larvae will stay at their birth reef in warmer seas

New research suggests that global warming is leaving large coral reef systems less interconnected, which can affect their ability to recover after disturbance and potentially deplete local populations. Catarina SilvaHi! I am a PhD candidate at Victoria University of Wellington. I study the genetic structure of organisms and how the environment influences genetics. Check out […]

How Coral Size Influences Fish Size

Many fish find a coral colony to host in, living their whole life in that same coral. They must pick carefully, however, for the shape and size of the coral will determine how the fish will grow. Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins and […]

Coral Invasion in the Gulf of Mexico

The black sun coral is “invading” the Gulf! Once settled, it could out-compete other benthic epifauna and change the dynamic of the region’s community structure. Valeska UphamFor my fisheries and aquatic science PhD I am working on how to tank raise urchins and transplant them onto reefs across the Florida Keys in order to help […]

Is Aragonite Saturation State (Ωa) the Best Way to Describe Calcification Rate?

Nearly every scientific report concerning the effects of ocean acidification on coral reefs describes changes in calcification as a function of the aragonite saturation state (Ωa). Is this the best parameter that we can use to represent calcification condition? Are there any other options? Caoxin SunCaoxin is a graduate student in the Graduate School of […]

Coral Reefs Suffering from Ocean Acidification

Researchers investigated natural trends in carbonate chemistry of the Davies Reef flat in the central Great Barrier Reef on diel and seasonal timescales. They found the reef flat is below a calcification threshold, which implies that a transition in the reef may occur from a state of net calcification to dissolution, around 26.9% of the […]
