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...

A method for estimation of generalized linear models when explanatory variables contain meaurement error

Creator:

Sauter, Roger M.

Abstract:

This thesis considers the problem of estimating the linear parameters of generalized linear models (GLM), especially binomial and Poisson regression models, when the explanatory variable is subject to measurement error. In this situation, the dependence of the response variable on the observed explanatory variable cannot typically be modeled as a...

Diagnostic tools for overdispersion in generalized linear models

Creator:

Ganio-Gibbons, Lisa M.

Abstract:

Data in the form of counts or proportions often exhibit more variability than that predicted by a Poisson or binomial distribution. Many different models have been proposed to account for extra-Poisson or extra-binomial variation. A simple model includes a single heterogeneity factor (dispersion parameter) in the variance. Other models that...
