Sea otters in the kelp forest

sea otters in the kelp forest Both sea urchin and kelp abundance differed significantly among locations with vs without sea otters in the aleutian islands and southeast alaska there was little (aleutian islands) or no (southeast alaska) overlap between sites with and without sea otters, in plots of kelp density against urchin biomass.

While sea otters were unaffected by wasting disease and continued to eat large urchins, the populations of medium-sized urchins exploded by over 300% and the density of kelp forests declined by 30. Sea otters play an essential role in the health of monterey bay's kelp forest and estuary ecosystems they eat sea urchins and other animals that graze on giant kelp, keeping them in check so the kelp forests can thrive and support a rich community of plants and animals. Here, sea life is attracted to the kelp forests for nutrients and sanctuary the canopy, columns and seabeds provide habitat for crustaceans, invertebrates and all manner of fish species the fronds are also a favourite for weedy sea dragons and pot-bellied seahorses, which, when spotted, convey the true otherworldliness of this magic destination. Concluding points i sea otters have a strong direct negative effect on kelp forest invertebrates (shellfish) ii this direct negative effect on invertebrates results in a strong indirect positive effect on kelp abundance and distribution. One of kelp's predators is the sea urchin sea otters eat sea urchins, that is how they help kelp (that rhymes.

Sea otters’ presence is crucial in keeping the ecosystem balanced and the kelp forests healthy and thriving and, even if you live far from the pacific ocean, that matters to you because kelp forests are one of the ocean’s great carbon sinks they help mitigate the effects of climate change. Without sea otters, these grazing animals can destroy kelp forests and consequently the wide diversity of animals that depend upon kelp habitat for survival additionally, kelp forests protect coastlines from storm surge and absorb vast amounts of harmful carbon dioxide from the atmosphere. Sea cows lived in kelp forests and fed on kelp, thus raising the question of the relative importance in driving the sea cow’s demise of the direct effects of human exploitation vs the indirect effects of reduced food or altered habitat caused by the ecological extinction of sea otters. One of the sea otter's favorite delicacies is the sea urchin who in turn loves kelp when present in healthy numbers, sea otters keep sea urchin populations in check but when sea otters decline, urchin numbers explode and grab onto kelp like flies on honey.

An otter-assisted kelp forest can absorb as much as 12 times the amount of co2 [carbon dioxide] from the atmosphere than if it were subject to ravenous sea urchins, according to the study. By controlling the size and number of sea urchins (sea urchins are one of their favorite foods, and they eat the larger ones first), sea otters created the opportunity for kelp to grow and flourish, which in turn created habitat for numerous other kelp forest dwellers. The mutually beneficial symbiotic relationship between sea otters and kelp is essential to the health of the entire kelp forest ecosystem sea urchins found in kelp forests typically eat drift kelp, but when it is scarce they eat living kelp plants. Sea urchins pose a humongous threat to kelp forests because they multiply quickly and eat at the holdfasts (roots) of kelp forests, feeding on the kelp frond where it attaches to the ocean floor.

Sea otters prey on the sea urchins, which helps the kelp forests the sea otters keep the population of sea urchins down, which allows the kelp forests to grow, & helps keeps kelp forests from being destroyed we need kelp forests because they provide biodiversity. One of the kelp forest’s most endearing denizens, the sea otter, is an important key to its survival in some places this valuable kelp carbon store is disappearing, mown down by a hungry army. Kelp forest ecosystems as the former can cause “deforestation” and the latter have severely declined due to overfishing and, more recently, disease recent research suggests that sea urchin population.

Sea otters in the kelp forest

Sea otters have been found to play a pivotal role in the habitat and marine life that inhabit a kelp forest in a kelp forest, sea urchins can graze on the kelp and eat their holdfasts , resulting in deforesting the kelp from an area. February 1995 sea otters and kelp forests in alaska 77 abiotic processes, and that the role of sea otter pre- dation has been overemphasized and overgeneralized. Among the many mammals and birds that use kelp forests for protection or feeding are seals, sea lions, whales, sea otters, gulls, terns, snowy egrets, great blue herons, cormorants, and shore birds these dense canopies of algae generally occur in cold, nutrient-rich waters.

  • Large gatherings of sea urchins (a primary herbivore in kelp forests) can prevent kelp plants from growing large enough to form forests the cycle between these so called “urchin barrens” and well-developed kelp forests is a well-studied phenomenon in regions that are favorable for forest formation.
  • Sea otters, because of their eating habits, are considered a “keystone predator,” predators that keep the ecosystem balanced kelp forests decline and suffer when the otter population declines, as they are the main predator of sea urchins.
  • Sea otters were once top predators in channel islands national park's kelp forests they were extirpated as a result of heavy hunting, and while they are recovering in other parts of california, they have yet to return to the channel islands.

6 3 studying sea otters, both in the wild and at the monterey bay aquarium, helps us to better understand and protect them observe the otters closely. Why do you think sea otters have done better in washington state than in other areas, such as oregon and northern mexico, where the animals once lived look in the library and on the internet to learn what animals live in a kelp forest. Sea otters in the kelp forest the kelp forest is among the most biologically productive marine habitat known to earth today they are like underwater forest made out of giant kelp, and sustaining hundreds of different organisms such as kelp, abalone, crustaceans, urchins, harbor seals, and also sea otters.
