Photosynthesis of ,: effects of temperature and light on pigment concentration, C/N ratio and cell-ecreased with irradiance except in the case of carotenes. Carbon and nitrogen were maximal at maximal photosynthetic rates, and the C: N ratio increased with increasing irradiances together with increases in cell-wall polysaccharides.

Chemical structure and physico-chemical properties of agar,co-chemical methods have evolved, particularly molecular-weight determinations, X-ray diffraction data and molecular modelling of agar, correlations between chemical and functional properties of agar and agarose and their gelation mechanisms remain to be studied.

Intrageneric differences in cystocarp structure in , and ,,, with ostioles opening to both surfaces; however, unequally developed locules have been described in . and differences in cystocarpic architecture between . and the type species of the genus, ., have been recently found. As heterogeneity in cystocarp architecture raises questions of basic intergene

Worldwide distribution of commercial resources of seaweeds including ,,d harvested for each purpose are tabulated and discussed. Seaweeds for food are derived chiefly from China, Japan and Korea, with almost 94% obtained by cultivation. Alginophytes are collected in 15 countries but six of these account for more than 80% of the total harvest; all are from natural stock

Biological criteria for the exploitation of the commercially important species of , in Spain, of their use as resources for the extraction of agar. This resulted in the implementation of several harvesting methods, the most important of which is the gathering of cast seaweeds, both from the shore and the sea. From the very beginning, direct exploitation of these species .. plucking) was con

, in South Africa,as been intensively studied since 1983, and we briefly review knowledge of its biology in relation to harvesting. We describe a new study of intertidal epiphytic animals, showing that none is specific to .,and that only 2.8% of these animals (numbers) inhabit this agarophyte, while the rest are foun

Field studies and growth experiments on , from Asturias (northern Spain),are given, and non-parametric correlation is used to quantify possible relationships. The results are compared with growth experiments, testing effects of total light dosage, agitation, temperature and Photon Flux Density .. Results of total light dosage × agitation growth experiment show that maxim

Photosynthesis of ,: effects of temperature and light on pigment concentration, C/N ratio and cell-system of high temperatures and high photon fluences. The plants were photoresistant and showed saturation of photosynthesis near a PFD of 300 µlimo’ m . s .and a compensation point under 100 µmol m. s .. Temperature and irradiance have a synergistic effect on photosynthesis. Pigment concentration d
