Diverse consumer guilds in intertidal communities of Oregon and the Republic of Panama and their effects on prey assemblages

Creator:: Gaines, Steven D.
Abstract:: Low intertidal communities of Oregon and Panama have many predator and herbivore species. This diversity of consumers is important to the organization of both communities because of qualitative differences among the consumer species in their ability to circumvent specific prey defenses. In Oregon, the red alga Iridaea cordata is protected...

Population and community ecology of the red alga Rhodomela larix (Turner) C. Agardh, on the central Oregon coast

Creator:: D'Antonio, Carla Marie, 1956-
Abstract:: Aspects of the life history and ecology of the intertidal turf-forming alga Rhodomela larix (Turner) C. Agardh were examined over a two year period at several sites on the Oregon coast. Rhodomela occurred over a broad tidal range and exhibited different growth and morphology characteristics with respect to tidal height....

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....

An experimental test of optimal outbreeding in the harpacticoid copepod Tigriopus californicus (Baker)

Creator:: Brown, Alice F.
Abstract:: Hypotheses concerning relative costs of inbreeding and outbreeding were evaluated for the harpacticoid copepod Tigriopus californicus, which inhabits high intertidal tidepools. Field studies indicate high variation in biotic and abiotic parameters among pools. These findings coupled with previous information about very low dispersal rates and local adaptations to individual pools...

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...

Marine herbivore-plant interactions : the feeding ecology of the sea slug Placida dendritica

Creator:: Trowbridge, Cynthia D.
Abstract:: The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...

The effects of biomechanical and ecological factors on population and community structure of wave-exposed, intertidal macroalgae

Creator:: Blanchette, Carol A.
Abstract:: I examined the biomechanical factors that influence the sizes of intertidal macroalgae by studying a population of Fucus gardneri at Fogarty Creek Point, OR. I constructed a mathematical model to predict optimal sizes and probabilities of survival for Fucus under conditions of high and low wave exposure. Predicted optimal sizes...

Bottom-up and top-down forces in tidepools : the influence of nutrients, herbivores, and wave exposure on community structure

Creator:: Nielsen, Karina Johanna
Abstract:: The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...

Oceanographic influences on rocky intertidal communities : coastal upwelling, invertebrate growth rates, and keystone predation

Creator:: Sanford, Eric (Eric David)
Abstract:: The influence of large-scale processes on natural communities has become one of the central issues of modern ecology. I combined field and laboratory studies to investigate the effects of variation in coastal upwelling on rocky intertidal communities along the central Oregon coast. I examined whether the growth of intertidal barnacles...
