Found along the west coast of North America, red sea urchins (Mesocentrotus franciscanus) call the ocean bottoms home. There, these spiky creatures feed on seaweed and kelp, and are often found in groups. While they may face predation from sea stars and crabs, the urchins, when left to their own devices, age phenomenally well. In fact, some researchers even report their lifespans as being over 100 years long.

In an innovative collaboration, BIOS molecular ecologist Leocadio Blanco-Bercial and reef ecologist Tim Noyes are exploring how DNA can be recovered from seawater to reveal which fish species are active on Bermuda’s reefs. As fish swim, water passing over their gills and waste passing through their guts all deliver sloughed off cells to the surrounding seawater, leaving a trail of genetic material behind them. Within that genetic material, a specific short sequence of DNA can be recovered by scientists and traced like a fingerprint to a single fish species. But to learn more about fish communities from the DNA sequences swirling in the seawater, scientists first need to document which sequence belongs to which species.

An interdisciplinary team of scientists joined forces in July for their first annual research cruise dedicated to revealing how specific microbes take up and transform organic matter within a web of ecological interactions in the waters southeast of Bermuda.

BIOS scientists gained a fresh perspective on six-month-old mustard coral larvae (shown in photo above) and tiny lionfish eggs (photo below) using a new microscope at the Institute.

Sampling offshore Bermuda this July, the BIOS-SCOPE (Bermuda Institute of Ocean Sciences – Simons Collaboration on Ocean Processes and Ecology) program completed its first full year of study to learn how marine microbes produce, transform, and leave behind dissolved organic matter as the seasons progress, and microbial communities wax and wane.

A molecular facility will enhance sample processing for researchers and experiential learning for students

Chloe Emerson initially came to BIOS in the fall of 2014 for the Research Experiences for Undergraduates (REU) internship program funded by the National Science Foundation.  As a Wellesley College senior working to complete her major in Biology and minor in Philosophy, Emerson already found developmental biology and stem cell research fascinating. At BIOS, these interests crystalized as she began to study sea urchins in Andrea Bodnar’s Molecular Discovery Laboratory, leading her down a path in regenerative biology that she hardly could have imagined two years ago.

When you consider ways to study the process of aging in humans, you might not consider looking to one of the ocean’s most widely-studied invertebrates—the sea urchin—but that’s exactly what BIOS researchers Dr. Jeannette Loram and Dr. Andrea Bodnar did in a recent study published in the journal Mechanisms of Ageing and Development.

Some of our achievements in 2012 using ocean science for human good include work to:

This month marks the first year that students at Furman University can take the “Oceans and Human Health” (OHH) course at BIOS for their May Experience, an optional three-week term following commencement that allows students to participate in unique academic experiences, including shorter study abroad courses and instruction in research methods. Coordinated by BIOS’s Dr. Andrea Bodnar, the course is offered through the International Center for Ocean and Human Health at BIOS, which was established in 1998 to encourage interdisciplinary research among the ocean and medical sciences.
