Pterygophora is a monotypic genus found from Vancouver Island to Lower California where it grows characteristically at the bottom of deep chasms possessing 12—15 ft. of water at low has been estimated that individual plants may live.

    Alternatively, rapid recovery may result from colonization by dormant stages that survive disturbance. Here we test for reproductive synchrony as a way of extending the dispersal potential of two common seaweeds, the kelps Macrocystis pyrifera and Pterygophora californica.

Ruprecht and Carl Wahren.]' -- subject(s): Progress, Economic development, Population.

    The gametophytes of 9 laminarian species (4 from southern California, and 5 from central California, USA) became fertile in the unicellular stage (female gametophytes) or in a few-celled stage (male gametophytes), when appropriate temperatures and a sufficiently high quantum irradiance in the blue part of the spectrum were supplied. Vegetative growth, leading to the formation of filamentous. life-history stages. Between September and January , the roles of temperature and nutrient avail-ability in explaining the southern distributions of two understory kelps, Pterygophora californica and Eisenia arborea (Phaeophyceae, Laminariales), were investi-gated along the .

The life-history of Pterygophora californica Ruprecht. [Hazel Hayden McKay]. Pterygophora californica is a large species of kelp, commonly known as stalked is the only species in its genus Pterygophora (Ruprecht, ). It grows in shallow water on the Pacific coast of North America where it forms part of a biodiverse community in a "kelp forest".Class: Phaeophyceae.

A canopy removal experiment was performed in Monterey Bay, California, USA, to determine the physiological response of the understory kelp, Pterygophora californica Ruprecht, to shading by the giant kelp, Macrocystis pyrifera C.

Agardh. The day experiment was carried out at the end of the summer of when surface canopy development was at a maximum. Macrocystis pyrifera formed a surface canopy at eight sites, and bull kelp, Nereocystis luetkeana (Mertens) Postels & Ruprecht, at one site.

The understory kelps Pterygophora californica Ruprecht and Laminaria setchellii P.C. Silva and the bat star Asterina miniata Brandt were the most abundant organisms counted as individuals. Global Biodiversity Information Facility. Free and Open Access to Biodiversity Data. Restriction enzyme mapping of the nuclear ribosomal cistron was completed for a variety of Laminariales.

Taxa investigated included Alaria marginata Postels and Ruprecht, Egregia menziesii (Turner) Areschoug, Eisenia arborea Areschoug, Lessoniopsis littoralis (Tilden) Reinke, Macrocystis integrifolia Bory, Nereocystis leutkeana (Mertens) Postels and Ruprecht, Postelsia palmaeformis Ruprecht.

The zoospores of Pterygophora californica Ruprecht and Macrocystis pyrifera (L.) C. Agardh are chemotactically drawn to nutrients (Amsler and Neushul).

It is possible that the zoospores find the red algae based on released photosynthate (Kremer ) or chemical signals from the red algae. Life History: alternation of heteromorphic phases, with a macroscopic sporophyte and dioecious microscopic gametophytes (Cole b, p.

Urchins were fed one of five macroalgal diets: a monospecific diet of either Macrocystis pyrifera, Pterygophora californica, Rhodymenia californica, or Chondracanthus corymbiferus, or an equal mixture of all four species (hereafter referred to as a mixed diet) with n = 7 urchins per diet type.

List of Species with Authorities. This list contains all of the scientific names mentioned in this guide, including names of non-seaweeds. Where a seaweed has undergone a recent name change or there is a conflict as to which is the proper name, we have listed both the new and old names (e.g., Aegagropila was Cladophora) so that the reader can recognize organisms described in the older literature.A cytological examination of the life-history of Nereocystis luetkeana has shown that an alternating chromosome number corresponds to the morphological alternation of generations.

The first division sequence of the zoosporangial nucleus is meiotic and is followed by three mitotic divisions. The result is a mature sporangium containing 32 nuclei. Thirty-two zoospores are liberated from each.Pterygophora californica. Lessoniaceae.
