  Kelp Forests
Nereocystis luetkeana often dominates northeastern Pacific kelp forests.
The very upper story Nereocystis is an annual plant, however, and it and other species are slowly displaced by Laminaria groenlandica, which shades and inhibits the growth of newly arrived spores.
Unlike Nereocystis luetkeana, Macrocystis pyrifera is not an annual.

 Nereocystis luetkeana
Viewed from underwater, the canopy is a analogous to a forest canopy.
Plants consist of a long stipe (up to 36 m/118') attached to the ocean floor by a holdfast composed of numerous haptera (finger-like projections) and terminated above, on the ocean surface, by a single float from which a cluster of tightly branched smooth blades arise.
The spores are produced on the blades at the ocean surface, often several metres above the ocean floor, but a critical concentration of spores is required near where the parent plant is successfully established to assure re-occupation of this optimal space once the annual plant is lost.

To investigate whether novel polyphenolic constituents, that have been reported to contribute considerably to dissolved organic matter (DOM) and particulate organic matter (POM), are of algal origin, a number of algae, i.e.
the brown macroalgae Nereocystis luetkeana, Fucus gardneri, Costaria costata, Sargassum muticum, a green macroalga Ulva fenestrata, a red macroalga Opuntiella californica and a microalga Rhodomonas sp., were subjected to analytical pyrolysis.
Alkylphenols were encountered in the pyrolysates of all algae, and in the residues obtained after acid treatment of N. luetkeana and U. fenestrata.

Fucus gardneri dominates in the intertidal zone while a variety of kelps (Agarum cribrosum, Laminaria spp., and Nereocystis luetkeana) and eel-grass (Zostera marina) are domi-nant in the subtidal zone.
Nereocystis habitats are located on exposed sites, and the algal diversity was higher than in the other two habitats.
The kelp forest structure at these locations consists of a canopy of Nereocystis luetkeana with an understory of L.

There are three common types of canopy-forming kelps found in Alaska: Macrocystis (M. pyrifera and M. integrifolia), Nereocystis luetkeana, and Alaria fistulosa.
N. luetkeana, generally known as bull kelp, is the most common kelp in Alaska ranging from the eastern Aleutians to southern California.
Nereocystis and Alaria are annuals and therefore grow to their massive size in just part of one year.

Nereocystis luetkeana, the major surface-canopy forming kelp in Kachemak Bay, has a distribution that appears to be dictated by the salinity and turbidity gradients.
I propose to map the spatial distribution of the kelp beds of Kachemak Bay using aerial photography and GIS technology and to investigate the role of salinity and turbidity gradients in the distribution pattern.
I will conduct tank experiments and in-situ replacement studies in order to correlate the survival and growth rates of Nereocystis luetkeana with different salinity and turbidity conditions.

Bull kelp (Nereocystis luetkeana) forms underwater forests along the coasts of Oregon, Washington and California.
Bull kelp provides refuge for many species of rockfish, a resting area for shorebirds, waterfowl, and sea otters, and shelter to crabs, shrimp, sea cucumbers and other marine creatures.
PMCC will work with relevant state agencies to revise applicable statutes and regulations, and limit harvest in order to effectively protect bull kelp beds.

Bull kelp (Nereocystis luetkeana) is a variety of seaweed with a long, hollow stem attached to a bulb with trailing leaves.
This plant grows abundantly in Kodiak's near shore waters and has a one-year life cycle.
Today, many gardeners mix bull kelp with eelgrass to produce a rich fertilizer.

If urchins are relatively sparse and disturbance infrequent, this species tends to take over.
It is a perennial, and shades out other species, including the annual Nereocystis luetkeana, which can grow to the surface, if it can get a start from the bottom.
When Laminaria is sparse this is possible, but when it is very dense, thalli shade out newly established sporelings of Nereocystis.

Bull kelp (nereocystis luetkeana), also known as bullwhip kelp due to its long stipe which resembles a whip, is found along the northwestern coast of the United States.
Often one can see children snapping their playmates or their parents with a shorter piece of it, or dogs dragging it along for a ways.
