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...
Two experiments were conducted to examine the effects of passive
immunization of pregnant mares with a monoclonal antibody [MAb, 518B7,
antibovine βLH which crossreacts with equine chorionic gonadotropin
(eCG)] on subsequent reproductive characteristics and changes in plasma
concentrations of hormones. In Exp.1 control mares (C, n=3) were not
treated. Another...
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...
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...
