Jackson, G.A. Ecosystems 7: 341-357. It is also the primary home of Stalkers and Hoverfish. The effect of removing one predatory species in this system differs from Alaska because redundancy exists in the trophic levels and other predatory species can continue to regulate urchins. Science 286: 1577-1579. Eckman and A.T. Sewell. Science 224: 283-285. Sea urchins like kelp - a lot - and, if their populations get too big, they may graze a kelp forest to death; if they remain, they may also inhibit the kelp's ability to grow again in that area. Suchovejeva and G.V. The spring season begins as March winds blow surface waters offshore. Changes in community structure in temperate marine reserves. Generally speaking, kelps live further from the tropics than coral reefs, mangrove forests, and warm-water seagrass beds, so kelp forests do not overlap with those systems. Winter storms can also affect the growth cycle of kelp by tearing holes in the canopy, pruning fronds from kelp, or even dislodging entire kelp plants from the sea floor. Community-wide distribution of predator-prey interaction strength in kelp forests. Marine protected areas (MPAs) offer a unique solution that encompasses not only target species for harvesting, but also the interactions surrounding them and the local environment as a whole. 2003. Kelp also produces oxygen. Some kelps form dense patches on rocky reefs resembling a forest of trees underwater and are referred to as kelp forests. Kelp is food for abalones such as the California Red Abalone. Edwards, K.L. The transition from macroalgal (i.e. A wide range of sea life uses kelp forests for protection or food, including fish. Adding exercises that involve reading, writing, math, history, and civics will give students a more meaningful understanding of the content. Cool facts. Kalin and S. Davis. Shears, J.W. Graham. [21] However, the removal of multiple predators can effectively release urchins from predator pressure and allow the system to follow trajectories towards kelp forest degradation. [61] Modern economies are based on fisheries of kelp-associated species such as lobster and rockfish. 1967. kelp forest unit, even if your emphasis is on science. 2006. Quests are fun and you get a sea horse mount! [6] The most widely recognized species are the giant kelps (Macrocystis spp. Gell, F.R. Extrapolating even well-studied trends to the future is difficult because interactions within the ecosystem will change under variable conditions, not all relationships in the ecosystem are understood, and the nonlinear thresholds to transitions are not yet recognized. However, the influence of humans has often contributed to kelp forest degradation. Title: WHAT ARE KELP FORESTS 1 WHAT ARE KELP FORESTS? Multiple kelp species often co-exist within a forest; the term understory canopy refers to the stipitate and prostrate kelps. Scheibiling, R.E. Take a trip to the kelp forest and assemble a food web of the fascinating organisms there! Kelp has goopy stuff called phycocolloids in its cell walls. M.J. Tegner, P.B. Field, C.L. The leaf-like fronds contain air-filled bladders that help the kelp stalks float upright in the water, giving kelp beds the drifting appearance of an underwater forest. Hennigar. The kelp acts as giant sieves, straining larvae out of the water. They extend their leaf-like fronds into the waters above them reaching towards the sunlight. ), although numerous other genera such as Laminaria, Ecklonia, Lessonia, Alaria, and Eisenia are described. Jackson, G.A. Kevin Joe/California Department of Fish and Wildlife . James and L.G. The term kelp refers to marine algae belonging to the order Laminariales (phylum: Heterokontophyta). Norderhaug, K.M., Christie, H., 2009. The kelp forest is one of the most productive ocean ecosystems on Earth, supporting a greater diversity of plants and animals than almost any other marine habitat. Edwards, M.S. 2002. Nonpoint pollution of surface waters with phosphorus and nitrogen. In the absence of predation, these lower-level species flourish because resources that support their energetic requirements are not limiting. Annual Review of Ecology and Systematics 16: 215-245. Tilman, D., C.L. Sludge, silt or sewage dumped near kelp forests can bury new shoots of giant kelp. 1984. Kelp can stretch 2-30 meters or more (up to 60 m in Macrocystis pyrifera) from their anchors on the sea floor to the surface. Kelp (Fucus vesiculosus) is a type of brown seaweed, moderate in size, that grows in regions with cold coastlines, including those of the northwestern United States and northern Europe. In the North Pacific kelp forests, particularly rockfish, and many invertebrates, such as amphipods, shrimp, marine snails, bristle worms, and brittle stars. Sea otters also hide from predatory sharks in the forests, so the forest also provides a safe haven as well as a feeding habitat. Kelp can stretch 2-30 meters or more (up to 60 m in Macrocystis pyrifera) from their anchors on the sea floor to the surface. 2006. Ecological Applications 8: S79-S92. Kelp forests are phyletically diverse, structurally complex and highly productive components of coldwater rocky marine coastlines. Log In. Animal Aid Unlimited. Oikos 82: 425-439. Fishing for lobsters indirectly increases epidemics in sea urchins. When one swims between them, you will find loads of little fish, crabs, and other sea animals hiding in there. [20][25] Large-scale environmental disturbances have offered important insights concerning mechanisms and ecosystem resilience. 1998. Recurrent outbreaks of disease in sea urchins. This type of interdisciplinary teaching has also been proven to help information "stick” much more effectively. Howarth, A.N. Humans harvest kelp for it is rich in iodine, potassium, and other minerals, but the primary product obtained from giant kelp is alginate. 1982. Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines. Riser. 1999. And they’re one of the most dynamic ecosystems on Earth. Females give birth in water to only one young, which remains dependent on the mother until six… Includes 4 pieces of giant kelp plus 19 additional organisms to cut out, feeding information and fun facts, student reading and worksheet, pro tips and answer key. The morphological structure of a kelp thallus is defined by three basic structural units:[8]. Predicting understory structure from the presence and composition of canopies: an assembly rule for marine algae. The ear bones (otoliths) of kelp bass are occasionally found in Indian middens (refuse piles). Journal of Applied Phycology 18: 505-519. A kelp forest off of the coast of Anacapa Island, California, Giant kelp uses gas-filled floats to keep the plant suspended, allowing the kelp blades near the ocean surface to capture light for photosynthesis, Sea urchins like this purple sea urchin can damage kelp forests by chewing through kelp holdfasts. Email or Phone: Password: Forgot account? [12], Frequently considered an ecosystem engineer, kelp provides a physical substrate and habitat for kelp forest communities. Modern economies are based on fisheries of kelp-associated species such as lobster and rock-fish. Food availability, sea urchin grazing and kelp forest community structure. Andrew, N.L. Kelp can grow to be one hundred feet tall! When sufficient drift kelp is available, herbivorous grazers do not exert pressure on attached plants; when drift subsidies are unavailable, grazers directly impact the physical structure of the ecosystem. 1994. They grow in dense groupings much like a forest on land. Kelp is a type of seaweed (or marine algae) that describes 27 genera worldwide. Osman. The ecology of giant kelp forests in California: a community profile. Lucas. Dugan, K.D. This creates upwelling as nutrient-rich waters are brought up from the depths. and M.N. They provide home to many fish and invertebrate species. Water clarity is a key factor determining the depth of water a kelp forest can thrive in, as sufficient light must reach the depth where kelp are anchored to the sea floor and first start to grow. Bourque, R.H. Bradbury, R. Cooke, J. Irving, A.D. and S.D. Benefits beyond boundaries: the fishery effects of marine reserves. Kelp forest can take up to 20 times more CO 2 (per acre) from the atmosphere than land based forest. 1973. Marine Biology 51: 83-91. and C.M. Winant. Kaehler, S., E.A. We are happy to have selected the kelp for 2019 because it is deeply linked to the sea otters and the health of our oceans. Ecology of kelp communities. Kelp forests also provide birds with a refuge from storms. Catastrophic shifts in ecosystems. It's a "low floor, high ceiling" adventure in These structures provide the necessary buoyancy for kelp to maintain an upright position in the water column. Lafferty, H. Leslie, D.A. Kratz. Science 283: 950-954. Long term variability in the structure of kelp communities in northern Chile and the 1997-98 ENSO. Steneck, R.S. Use the portal to Vashj’ir (Kelp’thar forest) which becomes available to you at a ring of stones on the the plateau north of the Valley of Wisdom in Orgrimmar. Gulls, terns, egrets, great blue herons, and cormorants dine on the many fish and invertebrates living in the kelp. 1993. 1970. Proceedings of the National Academy of Sciences 99: 3678-3683. Especially productive kelp forests tend to be associated with areas of significant oceanographic upwelling, a process that delivers cool, nutrient-rich water from depth to the ocean's mixed surface layer. Create New Account. Millar and R.C. The boat that originally took you there will NOT appear at the docks again. Kelp have high N … Avdejev. Effects of kelps on recruitment of benthic invertebrates. 1975. Patterns of association between canopy-morphology and understory assemblages across temperate Australia. Kelp forests grow on hard, rocky surfaces where they can tangle their root-like holdfasts around the stone. Application of marine reserves to reef fisheries management. [62][63] Kelp forests are valued for recreational activities such as SCUBA diving and kayaking; the industries that support these sports represent one benefit related to the ecosystem and the enjoyment derived from these activities represents another. Deep-water kelp refugia as potential hotspots of tropical marine diversity and productivity. But the uptick in regional wildfires means that land-based forests might no longer seem like the safest bet. I LOVE this place. Protection of exploited fish in temperate regions: high density and biomass of snapper. 2006. As climate change creates more severe weather, kelp forests are becoming more and more important. 2003. Sign Up. 2005. Foster, M.S. Wheeler, W.N. Sludge, silt or sewage dumped near kelp forests can bury new shoots of giant kelp. Kelps are primarily associated with temperate and arctic waters worldwide. Sea urchins like kelp - a lot - and, if their populations get too big, they may graze a kelp forest to death; if they remain, they may also inhibit the kelp's ability to grow again in that area. Ecology of understory kelp environments. Giant kelp is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, and Australia. The kelp acts as giant sieves, straining larvae out of the water. Kelp forests are a type of marine ecosystem that is present around colonies of kelp; they contain rich biodiversity. Conservation Biology 15: 642-647. 1995. Bristow. One theory contends that the kelp forests that would have stretched from northeast Asia to the American Pacific coast would have provided many benefits to ancient boaters. A host of invertebrates, fish, marine mammals, and birds exist in kelp forest environs. Pearse, J.S. Physical disturbances in an Australian kelp community. Marine reserves are necessary but not sufficient for marine conservation. Kelp (Fucus vesiculosus) is a type of brown seaweed, moderate in size, that grows in regions with coldcoastlines, including those of the northwestern United States and northern Europe.There are several varieties of kelp: true kelp, which thrives in cool seas; giant kelp, and bladder kelp, which grow in the North Pacific. Therefore, kelp forests rapidly reach a "mature" status, in striking contrast to terrestrial forests, which may take hundreds of years to mature. In Southern California, kelp forests persist without sea otters and the control of herbivorous urchins is instead mediated by a suite of predators including lobsters and large fishes, such as the California sheephead. 2007. Kelp forests are a type of marine ecosystem that is present around colonies of kelp; they contain rich biodiversity. Proceedings of the International Congress on Systematic Evolution and Biology 2: 248-256. Kelp belongs t… 2004. II. Kelp Forest Ecosystem Kelp Forest Ecosystem Grades. In some species, the fronds are kept buoyant by gas-filled bladders. Halpern, B.S. Includes 4 pieces of giant kelp plus 19 additional organisms to cut out, feeding information and fun facts, student reading and worksheet, pro tips and answer key. Connell. Over the last century, they have been the focus of extensive research, particularly in trophic ecology, and continue to provoke important ideas that are relevant beyond this unique ecosystem. Beneath the Waves: Exploring the Hidden World of the Kelp Forest. They attach to rocks on the sea bottom by a tissue known as their holdfast, from which their flexible stems (known as a stipe) and leaf-like tissue (or fronds) grow into the water column. Bourque, D. Corbett. Oliveira Filho. California sea lions, harbor seals, sea otters, and whales may feed in the kelp or escape storms or predators in the shelter of kelp. The environmental factors necessary for kelp to survive include hard substrate (usually rock or sand), high nutrients (e.g., nitrogen, phosphorus), and light (minimum annual irradiance dose > 50 E m−2[14]). I. Temporal effects. 1998. Div... Div... Did you know that vast underwater forests carpet the ocean floor in some places? Expansion of a central California kelp forest following the mass mortality of sea urchins. Spatial heterogeneity, sea urchin grazing, and habitat structure on reefs in temperate Australia. Jones. Canopy kelps include the largest species and often constitute floating canopies that extend to the ocean surface (e.g.. Stipitate kelps generally extend a few meters above the sea floor and can grow in dense aggregations (e.g.. Prostrate kelps lie near and along the sea floor (e.g.. Encrusting coralline algae directly and often extensively cover geologic substrate. 1999. In California, there’s a focus on preserving wild lands with carbon credits, he explains. 2 27 kelp genera 3 High Diversity of Primary Producers 4 High Diversity of Consumers 5 Distribution 6 Macrocystis Morphology 7 Who Cares?

This page was last modified on 21 October 2020, at 15:17. 1998. Kelp plants have three basic structural units: The holdfast is a root-like tangle, which fixes a kelp to the sea floor or other anchoring surface. Response diversity, ecosystem change and resilience. Learn Kelp forest facts for kids. Babcock, R.C., S. Kelly, N.T. 1977. and M.J. Tegner. [31] The relative importance of top-down versus bottom-up control in kelp forest ecosystems and the strengths of trophic interactions continue to be the subject of considerable scientific investigation.[32][33][34]. Twitter; Facebook; Pinterest; Google Classroom; Email; Print; Credits Media Credits. [27][40][41] Recovery from intermediate states of deterioration is less predictable and depends on a combination of abiotic factors and biotic interactions in each case. Oikos 69: 476-498. Kelp grows extraordinarily quickly. Berger, K.A. Giant kelp is harvested as a source of algin, an emulsifying and binding agent used in the production of many foods and cosmetics, like ice cream, cereal and toothpaste. Each of these regions provides different niches for many types of animals and other plants. This section details the characteristics of kelp as it affects the kelp forest as an ecosystem. - Bay Nature Magazine", Kelp forests provide habitat for a variety of invertebrates, fish, marine mammals, and birds, "95pc of Tasmania's giant kelp is gone, scientists are in a race to save what's left", https://en.wikipedia.org/w/index.php?title=Kelp_forest&oldid=984772923, Creative Commons Attribution-ShareAlike License. Broitman. Kelp Forest. Kelp can grow as much as 18 inches in one day, according to the National Oceanic and Atmospheric Association. Harbor Seals, Sea Otters, Sea lions, Sea Bass, Swell shark, Angel shark, Horn shark. Every year, we elect an animal or a creature to be the honoree of the year. Kelp forests are a natural buffet for birds such as crows, warblers, starlings, and black phoebes which feed on flies, maggots, and small crustaceans that are abundant in kelp forests. Dayton, P.K. 1985. Not Now . 1983. Byrnes, J., J.J. Stachowicz, K.M. Ecology 75: 1320-1333. Delayed recovery of giant kelp near its southern range limit in the North Pacific following El Niño. However, large numbers of sea otters can deplete shellfish populations, conflicting with fisheries for crabs, clams, and abalones. Related Pages. But this habitat has been devastated by a warming ocean and a surge in the purple urchin population. Kelp PBC’s Earth Hero Honoree 2019. Kelp forests are defined as underwater areas with dense groupings of kelp, similar to that of a forest of trees found on land. Kelp also produces oxygen. Effects of local deforestation on the diversity and structure of Southern California giant kelp forest food webs. Positive and negative effects of organisms as physical ecosystem engineers. The kelp forests would have provided many sustenance opportunities, as well as acting as a type of buffer from rough water. On the ocean surface, the stalks flower into a thick canopy that rests and rolls on the waves. Kelp is massive brown algae, not a plant species. Allison, G.A., J. Lubchenco and M.H. 1997. Comment by plpgirl111 My most favoritest zone in the game! In fact, sea otters, in particular, have a pretty amazing relationship with kelp. Pre-K, K, 1 - 5. Christie, H., Jørgensen, N.M., Norderhaug, K.M., Waage-Nielsen, E., 2003. 2006. Proceedings of the National Academy of Sciences 104: 16576-16580. [64] With respect to kelp forests, major issues of concern include marine pollution and water quality, kelp harvesting and fisheries, invasive species,[6] and climate change. The ear bones (otoliths) of kelp bass are occasionally found in Indian middens (refuse piles). Is grown in the Northern and Southern Hemispheres 2.) For example, in southern Australia, manipulations of kelp canopy types demonstrated that the relative amount of Ecklonia radiata in a canopy could be used to predict understory species assemblages; consequently, the proportion of E. radiata can be used as an indicator of other species occurring in the environment.[59]. Marine Ecology Progress Series 189: 125-134. Sea otters also hide from predatory sharks in the forests, so the forest also provides a safe haven as well as a feeding habitat. Kelp and kelp forests Brown algae, also known as kelps, are a group of seaweeds in the order Phaeophyta. This is what keeps it flexible and slippery! The distribution of Laminariales in the North Pacific with reference to environmental influences. Catastrophic storms can remove surface kelp canopies through wave activity, but usually leave understory kelps intact; they can also remove urchins when little spatial refuge is available. 2001. Kelp forests can influence coastal oceanographic patterns and provide many ecosystem services. Bohnsack, J.A. [8] The region with the greatest diversity of kelps (>20 species) is the northeastern Pacific, from north of San Francisco, California, to the Aleutian Islands, Alaska. [17][18] This general absence of kelp from the tropics is believed to be mostly due to insufficient nutrient levels associated with warm, oligotrophic waters. Like those syst… Marine Ecology Progress Series 316: 17-22. These underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species. Walker and T.J. Willis. These bladders help hold the blades up closer to the ocean … 2004. Fishing, trophic cascades, and the structure of algal assemblages: evaluation of an old but untested paradigm. We are happy to have selected the kelp for 2019 because it is deeply linked to the sea otters and the health of our oceans. Hughes, S.V. and G. Hernández-Carmona. Temporal and spatial patterns of disturbance and recovery in a kelp forest community. For example, a Macrocystis canopy may extend many meters above the seafloor towards the ocean surface, while an understory of the kelps Eisenia and Pterygophora reaches upward only a few meters. This helps sunlight filter down to lower depths and creates gaps where new kelp plants can establish themselves. In ideal conditions, Giant kelp can grow 30-60 centimeters vertically per day. When sea otters are removed from the ecosystem (for example, by human exploitation), urchin populations are released from predatory control and grow dramatically. 1998. Ecological Monographs 69: 219-250. [71][72] Direct benefits of MPAs to fisheries (for example, spillover effects) have been well documented around the world. 1992. Marine Ecology Progress Series 40: 145-153. Dayton, P.K. [10][11] The implementation of marine protected areas is one management strategy useful for addressing such issues, since it may limit the impacts of fishing and buffer the ecosystem from additive effects of other environmental stressors. However, the influence of humans has often contributed to kelp forest degradation. Temporal and spatial scales of kelp demography: the role of the oceanographic climate. Kelp forests are recognized as one of the most productive and dynamic ecosystems on Earth! Kelp are large brown algae that live in cool, relatively shallow waters close to the shore. In southern California, they can grow around 30 cm per day. Humans can also harvest kelp directly to feed aquaculture species such as abalone and to extract the compound alginic acid, which is used in products like toothpaste and antacids. Strong top-down control in Southern California kelp forest ecosystems. Yet if in any country a forest was destroyed, I do not believe so nearly so many species of animals would perish as would here, from the destruction of kelp. One third of southern California’s kelp forests are found within Channel Islands National Park and Channel Islands National Marine Sanctuary. Parnell and P.B. Kelp, any of about 30 genera of brown algae (order Laminariales) that grow as large coastal seaweeds in colder seas of both the Northern and Southern hemispheres. Chadwick, T.A. Kelp forests have been important to human existence for thousands of years. [60] Indeed, many now theorise that the first colonisation of the Americas was due to fishing communities following the Pacific kelp forests during the last ice age. Theorists also suggest that the kelp forests would have helped these ancient colonists by providing a stable way of life and preventing them from having to adapt to new ecosystems and develop new survival methods even as they traveled thousands of miles. Frontiers in Ecology and the Environment 1: 488-494. For example, the occurrence of kelp is frequently correlated with oceanographic upwelling zones, which provide unusually high concentrations of nutrients to the local environment. Airamé, S., J.E. Warner. Bustamante, R.H., G.M. Stull, J.K. 1989. Lehman, and C.E. Dayton, P.K. [14] Water flow and turbulence facilitate nutrient assimilation across kelp fronds throughout the water column. [3], Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms[4] and are a source for understanding many ecological processes. Because kelp attaches to the seafloor and eventually grows to the waters surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water. Graham, B.J. Roberts. Nutrients and production of giant kelp. Kelp plants have three basic structural units: In addition, many kelps have pneumatocysts, or air bladders, located along the stipe or at the base of fronds, to help the kelp maintain a roughly vertical posture. Some species, such as Nereocystis, are annuals, while others such as Eisenia are perennials, living for more than 20 years. Of the more dominant genera, Laminaria is mainly associated with both sides of the Atlantic Ocean and the coasts of China and Japan; Ecklonia is found in Australia, New Zealand, and South Africa; and Macrocystis occurs throughout the northeastern and southeastern Pacific Ocean, Southern Ocean archipelagos, and in patches around Australia, New Zealand, and South Africa. 1998. [38][78][79], Underwater areas with a high density of kelp. In this episode of “Nature Boom Time,” Charlie and his team take their cameras underwater to explore a kelp forest in California. Kelp is a type of seaweed (or marine algae) that describes 27 genera worldwide. Riser, D.B. Marine Biology 84: 287-294. [76][77] Most importantly, MPAs can be effective at protecting existing kelp forest ecosystems and may also allow for the regeneration of those that have been affected. New species of the genus. Deysher and M. Hess. Effects of macroalgal dynamics on recruitment of a temperate reef fish. Forgot account? Given the complexity of kelp forests – their variable structure, geography, and interactions – they pose a considerable challenge to environmental managers. A high nutrient content, moderate water movement via wave action or current, and a hard base for attachment are also all necessary requirements for the establishment of a kelp forest. McPhaden, M.J. 1999. Schiel. Lawrence, J.M. Marine Biology 147: 273-279. Severe storm disturbances and reversal of community structure in a southern California kelp forest. We have been educating our community about the sea stars, dolphins, sharks, turtles etc, for the past few years. Catastrophes, phase shifts and large-scale degradation of a Caribbean coral reef. It provides a vertical infrastructure that is home to many fish and invertebrate species. Hey Teachers! Another major area of kelp forest research has been directed at understanding the spatial-temporal patterns of kelp patches. Thornber. Gutierrez, A., T. Correa, V. Muñoz, A. Santibañez, R. Marcos, C. Cáceres and A.H. Buschmann. [23][24] This allows kelp to grow and subsequently support herbivores, which in turn support consumers at higher trophic levels. Kelp forests draw their name from an analogy to forests on land. Genesis and evolution of the 1997-1998 El Niño. – Charles Darwin, 1 June 1834, Tierra del Fuego, Chile[2], Kelp forests occur worldwide throughout temperate and polar coastal oceans. Within mid-latitude belts (roughly 40–60° latitude in both hemispheres) well-developed kelp forests are most threatened by herbivory, usually from sea urchins. Marine Environmental Research 40: 181-224. These creatures eat the red sea urchins that can destroy a kelp forest if their population is not controlled. History of kelp beds (. Hey Teachers! Newell and M.I. Ecological Applications 8: 559-568. Science 314: 940-941. This suggests that their global model might actually be fairly accurate, and if so, kelp forests would be prolific in tropical subsurface waters worldwide. Ecology Letters 9: 61-71. Effect of a kelp forest on coastal currents. The kelp forest is one of the most productive ocean ecosystems on Earth, supporting a greater diversity of plants and animals than almost any other marine habitat. Lafferty, K.D. Branch and S.

The ecology of kelp bed communities in the Benguela upwelling system. 1987. [66][67][68][69], In many places, managers have opted to regulate the harvest of kelp[24][70] and/or the taking of kelp forest species by fisheries. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit. Kelp forests are characterized by extremely high rates of primary productivity, comprise the base of a complex food web, form a three-dimensional structure that provides physical shelter for many inhabitants, have large algal standing stocks within forests, and export substantial biomass as drift algae that support other coastal ecosystems (Graham et al., 2003; Stands of large brown algae in the order Laminariales (i.e., kelps) that provide food and shelter for a diverse array of marine plants and animals. Though not considered a taxonomically diverse order, kelps are highly diverse structurally and functionally. 2003. Compiling the Research: What a list of kelp facts my students generated! [65] The most pressing threat to kelp forest preservation may be the overfishing of coastal ecosystems, which by removing higher trophic levels facilitates their shift to depauperate urchin barrens. Facts about the Kelp Forest/Kelp 1.) The American Naturalist 151: 277-282. They occur worldwide throughout temperate and polar coastal oceans. We have been educating our community about the sea stars, dolphins, sharks, turtles etc, for the past few years. Great Facts & Tips about San Diego’s Kelp Forests. The dense vertical infrastructure with overlying canopy forms a system of microenvironments similar to those observed in a terrestrial forest, with a sunny canopy region, a partially shaded middle, and darkened seafloor. Humans can also harvest kelp directly to feed aquaculture species such as abalone and to extract the compound alginic acid, which is used in products like toothpaste and antacids.
