Marine Biology, 1994
The effect of bryozoan colonization on inorganic nitrogen acquisition by Agarum fimbriatum Harv. and Macrocystis integrifolia Bory., collected from the west coast of Vancouver Island, British Columbia, Canada, was examined in laboratory experiments during June and July 1992.

In 1983 and 1984 field plot experiments were established to assess the effects of a foliar applied (2 or 4L ha−1×four applications per season) kelpMacrocystis integrifolia, concentrate on growth and nutrition of bean,Phaseolus vulgaris. A commerical kelp concentrate, prepared fromEcklonia maxima, was also used as a test comparison.

Growth of Macrocystis integrifolia in Barkley Sound, Vancouver Island, B.C.
Canadian Journal of Botany, 1978Stipe elongation rates were measured over an 18-month period which included one normal summer and one in which there was unusually heavy epiphytism and defoliation. Calculated standard growth rates (G) followed atypical boreal pattern, rising in February through April, with a summer maximum of ca. 40 mm/day, and falling in October and November.

Planta, 1974
The stipe of Macrocystis integrifolia Bory, when cut near its base, released sieve-tube sap at a rate of 1.55 to 2.1 ml h(-1). This sap contained a high amount of ATP. When the sap was incubated with (32)PO4 (3-) the radioactivity was rapidly incorporated into a number of organic compounds, of which ATP was the most heavily labeled.

The general distribution of the brown alga Macrocystis integrifolia Bory in British Columbia is related to seasonal seawater temperatures and salinities. This species is restricted to regions having little seasonal variation of seawater temperature and salinity or regions where the lower salinities occur during the winter.

In a two year field investigation fresh kelp (M. integrifolia) was broadcast and incorporated into plots of silty clay loam soil in the lower Fraser Valley of British Columbia. The effects of this amendment on bulk density, particle density, total porosity and aeration (volume of pores occupied by air after a saturated core was allowed to freely drain ...

Polymorphism in macrocystis integrifolia bory in relation to water motion
2011A field study in three parts was undertaken to investigate the relationships between the habit of Macrocystis integrifolia Bory and water movement. Morphological variation in time within populations was related to seasonal changes in wind direction and speed. Four sites covering a wide range of exposures, yet characterized by essentially the same water

Numerous experimental studies have reported inducible defenses in macroalgae, but most of them have been conducted in laboratory environments where algae were maintained detached from the substratum and in artificial flow regimes. The results of those experiments might not reflect the natural situation, which can only be studied in situ.

Ash, mannitol, alginate content, and inclusion levels of 27 inorganic elements in the brown algae Macrocystis integrifolia and Nereocystis luetkeana were monitored monthly over a period of 2 years. In addition, the composition and viscosity of the alginate were determined.

Canadian Journal of Botany, 1983
Macrocystis integrifolia fronds are known to translocate photoassimilates at velocities of 35–72 cm/h. By means of 14C-labeled histoautoradiography it is shown that this translocation occurs in sieve elements, and, further, that it is the mature, fully differentiated sieve elements that have undergone selective hydrolysis of cell contents, including ...
