Rough, Rocky Shores Acting as Climate Refuges for Kelp Forests

On the coasts of British Columbia, habitat-forming kelp algae are on the decline. Sensitive to increasing temperatures, changing nutrient dynamics, and always at risk of being carved out of their coastal homes by storm activity, kelp seem to be on the losing side of global climate change more often than the winning. Considering the extensive […]

Size Matters in Kelp Forests – Big, Dense Populations Are Better Equipped to Recover from Disturbance

Kelp are habitat-forming species, the “ecosystem engineers” of our coasts. Standing metres tall and sheltering coastal habitats from the full force of the ocean’s waves, kelp provide a refuge for a variety of marine animals and create a forest ecosystem similar to what you might find in the temperate latitudes on land. They are nursery […]

Farmed Kelp to the Rescue? Not So Fast, Say Researchers

Kelp farming is on the rise across Europe and North America, and all the headlines say that’s a good thing for fighting climate change. But scientists say we need to make sure kelp farms don’t spawn even more environmental problems.    Grebe, Gretchen S., Carrie J. Byron, Adam St. Gelais, Dawn M. Kotowicz, and Tollef […]

On the case: Scientists use many sources to find the culprit in kelp disappearance

The extensive decline of the Great Barrier Reef has received a lot of press attention in recent years, yet reefs aren’t the only down-under ecosystem struggling. In a recent paper in Estuaries and Coasts, researchers Carnell and Keough from the University of Melbourne and Deakin University have reported an equally alarming decline in kelp forests […]

Holding fast: kelp in Nova Scotia tries to grow on turf algae after a period of decline

Kelp has had a few rough decades that have led to the decline that threatens not only kelp but the other species that use the algae for habitat. Researchers at Dalhousie University in Nova Scotia set out to determine if kelp can make a comeback from seas filled with turf algae. What they found is […]

Bite or Flight: How Seaweed Can Shape Feeding Behavior in Fish

What is a forest without trees or a coral reef without coral? Neither a forest nor a coral reef. Entire ecosystems are made possible by the living flora that define them; they provide shelter and hunting grounds for the animals which live in them. But what happens when the building blocks of these ecosystems are […]

Aliens in the kelp forests – community ecology and Miso soup

In the plant world, competition between species is almost always over space. Space dictates how much sunlight, nutrients, and potential mates you have access to. In community ecology, it’s thought that ecosystems only have so much space to offer different species, with some ecosystems containing more space than others. Most systems are also thought to be saturated so that, […]

The Kelp in the Coal Mine: can kelps act as an indicator for climate change?

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 […]

Kelp Deforestation: warming oceans are paving the way for seaweed eaters

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 […]

Kelp: It’s whats for dinner (or where you live)

Kelp is a kind of large algae that supports diverse ecosystems. These kelp forests may start receding as a result of ocean warming. How the organisms that live in these forests respond to the warmer environment and damaged kelp may determine how quickly that happens. Eric OrensteinEric is a PhD student at the Scripps Institution […]

If it you can’t stand the heat, get out of the kelp forest!

Kelp is a kind of algae that supports diverse ecosystems in the nearshore ocean. As the climate and ocean warms, however, these kelp could begin to die off. How, when, and why the kelp die has important consequences for species diversity that will affect ecosystem and fisheries management. Eric OrensteinEric is a PhD student at […]

Kelps forced into hiding: Underwater forests troubled by warm oceans

Kelp forests are highly productive and diverse ecosystems found in cool coastal waters. A new study suggests that warmer waters allow for great increases in predation on kelps, forcing these plant-like algae into a limited and sheltered life hidden within crevices. This could pose a major problem as global warming is leading to increasing ocean […]
