The coastal waters had common giant kelp species such as Durvillaea antarctica and Macrocystis pyrifera, which supported rich ecosystems that provided food, such as sea bass, cod, rockfish, sea urchins, abalones, and mussels for the migrating people. (smith.edu)
Integrifolia1
The smaller morphs, formerly identified as Macrocystis integrifolia, have deep brown color on flattened rhizomes which are profusely dichotomously branched. (wikipedia.org)
Algae3
Macrocystis is a monospecific genus of kelp (large brown algae) with all species now synonymous with Macrocystis pyrifera. (wikipedia.org)
Macrocystis pyrifera is the largest of all algae. (wikipedia.org)
The algae were selected as representing the major floral elements of the kelp bed (Macrocystis pyrifera) community. (hawaii.edu)
Durvillaea1
Here, we assessed the potential antiviral activity of aqueous extracts obtained from two brown macroalgae, namely Macrocystis pyrifera and Durvillaea antarctica against HSVs. (frontiersin.org)
Kelp forests2
Macrocystis is often a major component of temperate kelp forests. (wikipedia.org)
For instance, Macrocystis , a kelp of the order Laminariales , may reach 60 m (200 ft) in length and forms prominent underwater kelp forests . (wikipedia.org)
Pneumatocysts1
Macrocystis has pneumatocysts at the base of its blades. (wikipedia.org)
Grows1
M. pyrifera grows to over 45 m (150 ft) long. (wikipedia.org)
Shallow1
Shallow water grazers revealed stronger preferences for Egregia than for Macrocystis. (hawaii.edu)
Species1
Macrocystis is a monospecific genus, the sole species is M. pyrifera. (wikipedia.org)
Found1
In New Zealand M. pyrifera is found in the subtidal zone of southern North Island, the South Island, Chatham, Stewart, Bounty, Antipodes, Auckland and Campbell Islands. (wikipedia.org)
Growth2
While elevating pCO2 alone had no effect on M. pyrifera growth or photosynthetic carbon uptake, elevating temperature alone resulted in a significant reduction in both. (c-can.info)
However, when M. pyrifera was grown under elevated temperature and pCO2 together, growth and photosynthetic carbon uptake significantly increased relative to ambient conditions, suggesting an interaction of these factors on photosynthetic physiology. (c-can.info)
Kelp14
Macrocystis is a monospecific genus of kelp (large brown algae) with all species now synonymous with Macrocystis pyrifera. (wikipedia.org)
Macrocystis is often a major component of temperate kelp forests. (wikipedia.org)

(wikipedia.org)
During periods when kelp tissue nitrogen levels are low, but some inorganic nitrogen is available in the water column, oscillatory flow may enhance nutrient uptake by M. pyrifera by increasing the flux of nutrients into kelp canopies and by reducing the size of diffusion boundary layers at the kelp surface.
