Early succession in beds of the red alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae) : alternate pathways

Creator:: Olson, Annette M.
Abstract:: Multiple successional sequences have been observed following disturbance in communities on marine hard substrata. Observations of the turf-forming alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae), suggest that I. cornucopiae may assume its dominance by its ability to vegetatively pre-empt space. High limpet densities in the natural community, suggest that I....

Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

Novel icosanoids from the red marine alga Farlowia mollis

Creator:: Solem, Michele Lee
Abstract:: Farlowia mollis is a marine red alga that grows in the intertidal region along the coast of Oregon. We began studying the chemistry of this alga after a survey of Oregon seaweeds revealed possibly interesting chemistry and antimicrobial activity in its crude organic extract. Over the past three years the...

Evolutionary and ecological interactions affecting seaweeds

Creator:: Olson, Annette M.
Abstract:: The term "interaction" in evolutionary biology and ecology describes the relationships among variables in two classes of causal models. In the first, "interaction" refers to the influence of a single putatively causal variable on a variable of interest. In the second class of models, the term applies when a third...

Algal community structure and organization in high intertidal rockpools

Creator:: van Tamelen, Peter G.
Abstract:: Gradients of physical disturbance are central to theories of community organization yet rarely are studies performed in which physical factors are experimentally manipulated. Pothole tidepool algal communities exhibit distinct zonation patterns from top to bottom that result from scouring by rocks and other debris in the pools. Scouring is easily...

Effects of body size on the survival and timing of emigration of newly metamorphosed Northern Red-legged frogs

Creator:: Chelgren, Nathan D.
Abstract:: The purpose of this study was to investigate the survival and movements of newly metamorphosed Northern Red-legged frogs (Rana aurora aurora) as they emigrated from two ephemeral breeding ponds. Quantifying survival and movement rates will be important to our understanding how changes to terrestrial and aquatic systems affect behavior and...

The natural products chemistry of the red algae Ptilota filicina and Laurencia obtusa

Creator:: Lopez, Albert
Abstract:: The sea offers a wide variety of potentially useful resources. Marine algae have been a rich source of structurally unique natural products showing diverse biological properties. The current need to develop new antifungal, antibiotic, anticancer and antiviral drugs has prompted intense research efforts into the discovery, isolation and structure determination...
