As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change!
Climate change affects ecosystems worldwide, but how do conservationists decide which of planet earth’s ecosystems are most in need?
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.).

After migrating thousands of miles from their southern wintering grounds, males of a certain species of shorebird log thousands more miles scouring the summer territories for fertile females. It’s pretty nuts.
Fish have provided sustenance for millions of people, but in a world where stocks are rapidly depleting, what are the consequences of trying to save and rehabilitate their populations?
Most of the time coral reef communities are discussed, it seems the focus is whether they’re dominated by hard coral or algae. It turns out there may be other possible outcomes for reefs in the future. Find out more in today’s oceanbites!
Humans are drawn to beautiful beaches and warm water, and with us come the conveniences of modern day civilization. While life may be flourishing in the shops, restaurants and luxury hotels, this development is taking its toll on the fragile reef community just off shore. Although reefs may appear healthy to the naked eye, researchers have discovered coastal development impacts their biological diversity, and this may be an indication of more serious, long-term damage.
Atlantic killifish are spared extinction in the face of pollution thanks to their remarkable genetic diversity.
Mangroves are encroaching on salt marsh habitats worldwide, but what does this change in plant community mean for the plants, ecosystem processes, and other inhabitants of these areas? Find out a bit of the answer to that question in today’s oceanbites!
DNA from bacteria living in Antarctic sea ice provides a clue to the mysterious origins of methyl mercury in seawater in the Southern Ocean.
Ghost fishing is ghastly because it creates underwater graveyards for wildlife. The authors covered here wrote a new review of gear entanglement among mammals, reptiles, and sharks. Find out what they discovered by reading today’s post!
A glimpse of the thousands’ mile migration of the European eel shows it’s anything but straightforward.
Many believe we are in the midst of another mass extinction both on land and in the ocean. What marine animals are most at risk of extinction? Using current and past extinction data, researchers were able to pinpoint the most vulnerable types of marine animals.
Since 2005, southern right whale calves have been found dead in historic numbers off the Patagonian coast in Argentina. Scientists investigate whether harmful algal blooms may be to blame.
Using radiocarbon dating, scientists have discovered that the Greenland shark can live longer than any other known vertebrate. How long have some of these individuals been alive?
Whales aren’t the only animals hydrophones can detect out in the ocean. In fact, in the near future it might be possible to listen in on animals like scallops and determine if they’re healthy or not. Intrigued? Click here for more!
At the International Marine Conservation Congress this year, I got a first-timer’s look into the world of marine conservation research and in-depth discussions about the future of conservation.
As Shark Week drew to an end, the scientist that study sharks, fish, amphibians and reptiles joined together to discuss their scientific research with one another at the Joint Meeting of Ichthyologists and Herpetologists. Here are some of the highlights!
Manta and devil rays, closely related to sharks, are at serious risk of extinction due to overfishing. They are primarily being harvested for their gill rakers, which are a key ingredient in a new health tonic marketed by Traditional Chinese Medicine suppliers in China and South-east Asia.
