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 ...
The Evolution of Mate Choice in the Genus Limia
(2021-05-14)
Mate choice is a discipline of sexual selection research describing the process of an individual biasing resource use to reproduce with preferred mates. Classical theory describes mate choice as only occurring in females ...
The Spatial Distribution of, and Upland Impacts on, Playa Wetland Invertebrates
(2015)
Playa wetlands are a type of temporary wetland that are numerous in the Great Plains of the United States. Playa wetlands offer a unique habitat within semiarid grassland ecosystems. My research on the invertebrates of ...
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 ...
Aversive learning effect on odor coding in rat's piriform cortex
(2011)
Olfaction, a sense for detecting and discriminating chemical molecules in the environment, is critical for animal survival, reproduction and other adaptive behaviors. The olfactory system is organized in three major stations ...
A Multifaceted Approach to Reptile Conservation from Taxonomy and Systematics to Microbial Ecology
(2022-08-04)
Roughly one in five reptile species globally is threatened with extinction as of 2022. Further, nearly 15% of described reptile species are considered Data Deficient by the IUCN and their conservation status has not yet ...
Geographical variation in an aquatic-to-terrestrial resource subsidy pathway
(2021-05-14)
The redistribution of energy and materials across ecosystem boundaries (i.e. resource subsidies) can have substantial consequences for ecosystem processes but the magnitude of these effects are known to vary. Since most ...
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 ...
