Seagrasses are one of humans’ greatest sidekicks. They are nursery areas for many species including commercially important ones, they protect coastal communities from extreme weather, they absorb carbon dioxide and release oxygen via photosynthesis and much more. Now, research shows that seagrasses can also reduce rates of disease in humans, fishes and invertebrates such as corals. Read more to find out how!
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?
Article: Reynolds LK, DuBois K, Abbott JM, Williams SL, Stachowicz JJ (2016) Response of a Habitat-Forming Marine Plant to a Simulated Warming Event Is Delayed, Genotype Specific, and Varies with Phenology. PLoS ONE 11(6): e0154532. doi:10.1371/journal.pone.0154532 Climate change is poised to dramatically alter the make-up and functioning of Earths’ ecosystems, including those in the oceans. […]
Chemistry is important for a lot of things, but can it change the behavior of animals? Read on to find out how changes in water chemistry alter the behavior of a venomous cone snail!
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.
Global temperatures are increasing at a rate never before seen in Earth’s history. Although efforts to mitigate this are still very important, it is also important to study and understand what is going to happen to the plants and animals that live here. Evidence of climate change already surrounds us, and the more we know, the better prepared we will be to cope with our new environment. In this study, a group of researchers have studied how two species of clams react to a warmer environment to understand the coping mechanisms they use for survival.
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!
Many scientific studies have shown that kelp species are sensitive and vulnerable to climate change. Some scientists think of them as sentinel species, or early warning indicators of climate change. Recently, a large mass of warm water, affectionately known as “The Blob,” covered the northeast Pacific, resulting in a long-term elevation of ocean temperature. With existing ecological records of kelp forests in California, this provided an opportunity for researchers to test whether these giant kelps are indeed a sentinel species and can warn us about the looming effects of climate change.
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.
Excerpt: We’re taught at a young age that all food comes from the sun via photosynthesis. But, does it really? Read on to find out about a major fishery that is underpinned by chemosynthetic primary production!
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!
No, a Sharkcano is not a volcano that erupts sharks. IT IS WAY COOLER THAN THAT! It is a submarine volcano that hosts a diverse macro community in water that is much warmer and more acidic that the surrounding seawater. Read more to find out about this alien-esc ecosystem in the South Pacific Ocean.
It may seem like a harsh place to grow, but algae inhabit the under side of Arctic ice. As it turns out, these frozen, sea “veggies” provide an important source of food for Artic ecosystems.
Location, location, location. He may not need to be in the best school district, or have an easy commute to work, but Santa still decided to live at the North Pole over the South. While it may seem that both locations are cold, barren, and isolated, there are some fundamental differences that may have affected his decision. Read on to learn some of those differences and wow your friends with science at your holiday party this year!
As oceans heat up, tropical fish have started migrating to colder, temperate waters. The change in scenery from corals to kelp has plant-eating tropical fish drooling over the abundance of food in their new surroundings. After monitoring kelp habitat in Australia over a ten-year period, researchers found that this increase in tropical fish had some serious consequences for kelp forests.
Excerpt: The deep sea is not an easy place to live. Cold, dark, and featureless, it doesn’t provide a lot of food or hiding spots for the animals that live there. Read on to find out the odd way one species of crab has evolved to avoid both problems!
