Tigers, Bears, and Sharks, Oh My! Who’s the deadliest?

Bornatowski, H. et al. Geographic bias in the media reporting of aquatic versus terrestrial human predator conflicts and its conservation implications. Perspect Ecol Conserv. (2018). https://doi.org/10.1016/j.pecon.2018.12.004   Depends on where you live. Where humans and large animals meet, the results can be disastrous. While few conflicts with wild animals result in death, they can have […]

Severed Spinal Cord? Not a Problem for Sea Lampreys.

What if humans could regenerate our body parts? How can amputees or victims of central nervous system damage, for example, recover their very own limbs or physical movement? Scientists are hard at work, researching mechanisms that may answer these questions — and they’re drawing inspiration from marine life. Rishya NarayananRishya is pursuing an M.S. in […]

How do skates of the deep survive the crushing pressure?

On this Sharkbites Saturday we look at a fish that isn’t a shark at all! Here we explain how skates, the cousins of sharks and rays, use an interesting physiological mechanism to survive the pressure of the deep ocean. Carolyn WheelerI am currently a PhD student studying marine science at the University of Massachusetts Boston, […]

OSNAP! This is what we know about global ocean circulation

At the beginning of February, oceanographers published the first data from an ocean observing array 12 years in the making. The surprising results mark a turning point in our understanding of global ocean circulation. Oh snap. Nyla HusainI’m a 4th year PhD student at the University of Rhode Island Graduate School of Oceanography. I use models […]

Seeing Swarms from Space, Zooplankton in Action

Ever wonder how living creatures in the ocean can be seen all the way from space? A recent study by Basedow and co-researchers found that they could detect red colored zooplankton in images collected by satellites. Melanie FeenI am a first year graduate student at the Graduate School of Oceanography at University of Rhode Island. […]

You Light Up My World: Using Genetics to Understand How Velvet Belly Lanternsharks Produce Light

The velvet belly lanternshark, a deep sea shark species, can create its own light to attract prey and evade predators. How is it able to do this? A recent study uses cutting edge genetics technology to find out the genes involved in this process. sharnedI received my BS in marine biology from the University of […]

The Evidence of Things Not Seen: eDNA and Fisheries Stocks

Unlike fields of corn or herds of cattle whose yields are easily counted, wild fish stocks are more difficult to count. The ocean is a huge place, so finding and estimating populations to set future catch limits is really hard! There may be a new way of gathering this information though—one with less impact to […]

Long-term monitoring reveals optimistic future for endangered limpets

Monitoring species populations over is important if scientists want to understand how the species will persist into the future. Read on to see how one research group used long-term monitoring data to develop a future prognosis and conservation plan for the endangered Giant Limpet, an important marine invertebrate in the Mediterranean Sea. Katherine BarrettKate is […]

Lightheaded: Why some plankton may soon be gasping for breath

The amount of oxygen in the ocean is expected to decrease every decade due to climate change. In the Oxygen Minimum Zone, the area of the ocean with the least oxygen, what does this mean for the future of zooplankton? Kristin HuizengaI am a PhD candidate studying Biological Oceanography at the University of Rhode Island […]

Why Are Some Icebergs Green?

If someone asked you to imagine an iceberg, chances are you’d picture something big and white. However icebergs actually come in a range of colors from white, to blue, and even green. A recent study looks into what gives certain icebergs a unique green coloration. They find that iron oxide minerals are responsible, which could […]
