Current threats to coastal seagrass ecosystems

By Hanover Matz, RJD Intern If asked what marine ecosystems are currently most at risk, many people would probably identify coral reefs and mangrove forests. Climate change, sea level rise, and habitat degradation are all terms that come to mind when addressing the decline of corals and mangroves worldwide. However, equally important and at risk […]

What 19th century stories can tell us about modern fish stocks

By Stephen Cain, RJD Intern Shifting baselines, a term introduced by Daniel Pauly in 1995, occur when successive generations view contemporary environmental conditions as the baseline to measure future change against. The problem with this sort of bounded rationality is that it fails to account for long-term historic trends, and risks myopic decision-making in the […]

by Hannah Armstrong, RJD intern On Friday, February 27th the RJ Dunlap team set out for what we all anticipated to be a great day of shark research.  I was eager to head out into Biscayne Bay, as this was my first trip of the New Year.  I had the pleasure of being on a […]

Offshore Windmill’s Impact on the Marine Environment

by James Keegan, RJD intern Global demand for renewable energy is increasing as nations strive to decrease their carbon emissions, pollution, and dependence on non-renewable resources like coal or oil. Because of its energy output and potential to compete in energy markets, wind energy may be the most promising renewable energy (IEA 2013). Consequently, wind […]

Shark Tagging with Citizen Scientists

The morning was cool and windy, with some rough waves offshore. For everyone’s comfort, Captain Eric decided to stay closer to shore that day, taking us to the Safety […]

The Understanding of Giant Clams’ Contributions to Coral Reef Health Continues to Grow

by James Keegan, RJD intern Coral reefs suffer from a multitude of problems, such as global warming and ocean acidification, which can be deadly for the reefs. Other issues, like losing individual species, although troublesome, do not garner the same attention because they do not cause as much harm. However, each reef organism has their […]

The Consequences of the Indo-Pacific Lionfish invasion into Atlantic Waters

by Laurel Zaima, RJD intern The introduction of an invasive species into a foreign ecosystem has dire and often unforeseen consequences. An invasive species is considered any living organism that is not native to the ecosystem and causes harm to the local environment (“Invasive Species”). Non-native organisms alter the ecosystem, which affects the native species, […]
