Seasonal growth of the giant kelp Macrocystis pyrifera in New Zealand

We report the isolation and characterization of 16 microsatellite loci to study the population genetics of the giant kelp, Macrocystis pyrifera. Markers were obtained by screening a genomic library enriched for microsatellite motifs. Of the 37…

El Nino resulted in severe nutrient limitation and very low kelp productivity during the last half of 1983. Frond growth rates were so low that terminal blades formed before reaching the surface, eliminating the canopy. Frond initiation rates were…

Alginic acid, sodium alginate, and potassium alginate were extracted at the pilot-plant scale from Macrocystis pyrifera using our own technology published in previous papers. The alginates obtained were analyzed to determine if they fulfill the…

Abstract This study explores the potential cultivation of the giant kelp Macrocystis pyrifera (L.) C.A. Agardh in southern Chile, for the development of novel food products. The study demonstrates the importance of considering the collection site of…

The storm-related mortality rates of adult Macrocystis pyrifera in a Southern California giant kelp forest were determined over several winter storm seasons and compared with the hydrodynamic attributes of the most energetic storms. The data include…

It is generally considered that colonial invertebrates living on the surfaces of macroalgae have a negative influence on the growth rates and survivorship of their substratum. To date no evidence has been provided from natural macroalgal/epifaunal…

The giant kelp Macrocystis pyrifera is one of the largest and fastest growing seaweeds and is dominant over large areas of the west coast of North America. A model of its growth has been developed which describes plant biomass and production over…

The costs of self-fertilization were evaluated for the giant kelp, Macrocystis pyrifera. Macrocystis, like other kelps, has a biphasic life history in which the dispersal stage is the 1N spore generation. Once spores settle, they grow into sedentary…

This study examined the bioaccumulation of the heavy metals copper (Cu) and zinc (Zn) by the giant kelp, Macrocystis pyrifera, by exposing meristematic kelp tissue to elevated metal concentrations in seawater within laboratory aquaria. Specifically,…

ABSTRACT: Isotope values of primary producers can vary greatly across space and time due to changes in physiological status and the source of subsidies used in photosynthesis. Forests of the giant kelp Macrocystis occur in temperate oceans around…
