Kelp are large brown algae (Phaeophyta) that live in cool, relatively shallow waters close to the shore. There are about 30 different species of kelp worldwide. They grow in dense groupings much like a forest on land, and are found predominantly along the Pacific coast from Alaska to parts of Baja California.
How would you describe a kelp forest?
Kelp forests are defined as underwater areas with dense groupings of kelp, similar to that of a forest of trees found on land. And they’re one of the most dynamic ecosystems on Earth. These forests provide homes for tons of creatures like fish, invertebrates and marine mammals.
What role does kelp play in the ecosystem?
Like terrestrial forests, kelp forests provide an extensive ecosystem for many organisms from the sea floor to the ocean’s surface. While kelp is food for many organisms, kelp also provides shelter for many forms of sea life.
Where are kelp forests an important ecosystem?
Kelp forests grow predominantly along the Eastern Pacific Coast, from Alaska and Canada to the waters of Baja, California.
Why are kelp forests important to their ecosystem?
Kelp forests provide food, nursery areas, and shelter—including protection from predators and storms—for hundreds of commercially and recreationally important fish species as well as West Coast marine wildlife.
What is the role of the sun in the kelp forest ecosystem?
Kelp thrives in cold, nutrient-rich waters. Because kelp attaches to the seafloor and eventually grows to the water’s surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water.
What does a kelp forest look like?
Kelp Forests are underwater ecosystems formed in shallow water by the dense growth of several different species known as kelps. Though they look very much like plants, kelps are actually extremely large brown algae. Some species aggregate and spawn in kelp forests or utilize these areas as juvenile nursery habitat.
Is a kelp forest an ecosystem?
Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world’s coastlines. They are recognized as one of the most productive and dynamic ecosystems on Earth. Smaller areas of anchored kelp are called kelp beds.
What is unique about kelp forests?
They grow in dense groupings much like a forest on land. These underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species. Kelp forests harbor a greater variety and higher diversity of plants and animals than almost any other ocean community.
What kind of plants are in the kelp forest?
These include the giant kelp (Macrocystis pyrifera), oarweed (Laminaria setchellii), bull kelp (Nereocystis luetkeana), and featherboa (Egregia menziesii). Kelp forests have some characteristics in common with forests found on land. They are complex ecosystems that support many interconnected food webs.
What makes kelp forests unique?
Kelp forests harbor a greater variety and higher diversity of plants and animals than almost any other ocean community. Many organisms use the thick blades as a safe shelter for their young from predators or even rough storms.
How does climate change affect kelp forests?
The primary culprit is climate change: These giant algae need to be bathed in cool, nutrient-rich currents to thrive, yet regional warming in recent decades has extended the waters of the warmer East Australian Current into Tasmanian seas to devastating effect, wiping out kelp forests one by one.
What is the kelp forest?
The Kelp Forest is one of the most productive and dynamic ecosystems on Planet 4546B. It is also the primary home of Stalkers. It is located at medium-shallow depths, and is home to mostly passive life forms, with the only exceptions being Stalkers and Drooping Stingers.
How do kelps affect marine biodiversity and ecosystem functioning?
These changes will likely have significant impacts on marine biodiversity and ecosystem functioning because kelps are foundation species for a plethora of habitat-associated plants and animals, many of which are socioeconomically important.
What happens to kelp in the winter?
Storms and large weather events, like El Niño, can tear and dislodge the kelp, leaving a tattered winter forest to begin its growth again each spring. Kelp forests can be seen along much of the west coast of North America.
What is the average growth rate of kelp?
Its average growth (in spring) is 27 cm/day (~10 inches/day), yet it may grow up to 61 cm/day (2 ft/day). The average growth of bull kelp is 10 cm/day (~4 inches/day). The Kelp Forest Ecosystem A host of invertebrates, fish, marine mammals, and birds exist in kelp forest environs.
