Environmental constraints regulating the distribution and abundance of small mammals.
(1999)
I computed 15 landscape variables at four different scales (40 variables total). Cluster analysis of these weighted data produced three multispecies clusters based on associations of species distributions and abundances ...
Feeding ecology of juvenile turtles (Chrysemys) under experimental conditions /
(1984)
A foraging model that predicts the net energy intake for juvenile turtles feeding on a range of Callibaetis nymph sizes is also examined. Those nymph sizes that miximize the net energy intake in the model are considered ...
Status and ecology of Sotalia fluviatilis in the Cayos Miskito Reserve, Nicaragua.
(1999)
In March through May of 1996--98 we conducted research in the Cayos Miskito Reserve, Nicaragua to assess the status, ecology and distribution of Sotalia fluviatilis, a dolphin known from southern Brazil to Honduras. Surveys ...
An integrative approach to understanding mussel community structure: Linking biodiversity, environmental context and physiology.
(2007)
The focus of my third chapter is an integration of the physiology information collected in chapter two to address how species dominance of two distinct thermal guilds (thermally-tolerant and thermally-sensitive) influences ...
Correlates of extra-pair paternity and the effects of ectoparasites on nestling growth, parental provisioning and reproductive success in the house sparrow.
(2000)
In addition, I looked at another aspect of the reproductive biology of the House Sparrow, the effects of ectoparasites on nestling growth, parental provisioning and reproductive success. To determine whether Pellonyssus ...
Endocrine mediation of alternative mating tactics in toads: A proximate perspective on ecological patterns and sexual selection.
(2005)
Male Great Plains toads (Bufo cognatus) and Woodhouse's toads (Bufo woodhousii) alternate between one of two mating tactics; they may either vocalize to attract mates or they may adopt a non-calling "satellite" tactic. ...
Predicting breeding-bird occurrences in Oklahoma: Relationship of species distributions to land-cover and climatic variation.
(2007)
Predictive modeling for species distributions has received considerable attention in the past decade. As more data sets and better satellite images become available it is of interest to know how well modeling techniques ...
Trophic spatial ecology of invertivorous stream fishes.
(2007)
In Chapter 1, I studied the relationship between Bigeye Shiner populations and variables of habitat patches within the stream, and the land adjacent to the stream (the riparian zone). This work was done in Brier Creek, a ...
Multivariate analysis of salinity effects on mayfly distributions along a complex river continuum.
(1982)
The association between the benthic community structure and the river gradient as described in the river continuum concept is evaluated in the saline stressed Washita River. Physical, chemical and biological variables were ...
The effects of woody patches of habitat on grassland small mammals.
(2002)
To understand better the influence of habitat modifications on grassland ecosystems, I examined the effects of woody patches on the species richness, species diversity, and total density of grassland small mammals; the ...
