A tool for detecting giant kelp canopy biomass decline in the Californias

Journal of Phycology, 2023
AbstractKelp species provide many ecosystem services associated with their three‐dimensional structures. Among these, fast‐growth, canopy‐forming species, like giant kelp Macrocystis pyrifera, are the foundation of kelp forests across many temperate reefs. Giant kelp populations have experienced regional declines in different parts of the world.

A mathematical model for the growth of giant kelp

SIMULATION, 1974
A computer model in FORTRAN for the growth of the giant kelp, Macrocystis, which inhabits the coastal waters of southern California, has been developed. The present model considers only physical factors, water temperature and submarine light, as the factors that control the growth of single fronds in large kelp beds.

The effects of light on the growth and development of giant kelp

Hydrobiologia, 1984
Light influences photosynthesis and morphogenesis in both the gametophyte and sporophyte of the giant kelp Macrocystis (Luning & Neushul 1978; Luning 1981, Neushul et al. 1983). However, the large size and morphological complexity of the sporophyte complicates attempts to define clearly the role that light plays.

TRACE METALS IN GIANT KELP, MACROCYSTIS

American Journal of Botany, 1980
Concentrations of 38 elements present in Macrocystis tissues are listed. Mean concentrations of Cu, Zn, Fe, and Mn were similar for samples of juvenile and adult sporophytes from field sites. Cu in Macrocystis tissues rose above background levels when concentrations of 0.05 to 0.1 μm were added to the culturing medium.

EFFECTS OF SELF-FERTILIZATION IN THE GIANT KELP, MACROCYSTIS PYRIFERA

Ecology, 2004
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 and micro- scopic male or female gametophytes, which produce sperm and eggs.

Life-span of the Fronds of the Giant Kelp, Macrocystis pyrifera

Nature, 1961
THE large brown attached alga, Macrocystis pyrifera, member of a widespread genus, is of considerable importance as the direct and indirect source of food for a large number of near-shore animals; it is also gathered by man, to be used as fertilizer, food additives, and it is processed for certain of its chemical constituents.
