Making hypotheses precise: applying the physical method and linear modeling to evolutionary genomics
(2014-05-02)
Hypotheses in evolutionary genomics are commonly tested by qualitative comparisons among variables. However, the number of possible outcomes for such predictions is usually few, which can potentially trivialize or even ...
Maternal effects in Columbian ground squirrels
(2007-05-15)
The phenotype of an organism is the physical expression of its genotype and is a result of both the genetic makeup of an organism and the environment it experiences. An individual’s phenotype can also be affected by the ...
Maternal nesting behavior in lizards enhances colonization of urban environments
(2018-11-15)
Lizards occupy diverse habitats around the world from dense forests to arid deserts. The environments in which lizards exist pose different challenges for nesting females because embryo development is directly affected by ...
Mating Behavior of Columbian Ground Squirrels
(2008-08-15)
Columbian ground squirrels (Spermophilus columbianus) are diurnal, herbivorous, colonial, and hibernatory rodents that reside in the Rocky Mountains of western North America. During April-July in 2005-2007, field assistants ...
Mating Tactics and Reproductive Success in Male Columbian Ground Squirrels (Urocitellus columbianus)
(2010-12-06)
The widespread discovery of multiple mating tactics, particularly among males, highlights the diverse ways sexual selection may operate within a population. In polygynandrous populations, multiple paternity may arise from ...
Mechanisms and Evolution of Disease Resistance in Birds
(2017-01-04)
Disease outbreaks in wildlife, agricultural animals, and humans have increased in both frequency and magnitude in recent decades, refocusing research efforts on understanding the factors that influence disease emergence. ...
Methods for monitoring and controlling freshwater harmful algal blooms
(2013-11-08)
Fresh water is critical for our survival, and its responsible use is necessary for the sustainability of our planet. Surface-water ecosystems are important sources of recreation and potable water are threatened by increasing ...
Microhabitat Associations of Wintering Birds in a Southeastern Bottomland Forest within the Eastern Gulf Coastal Plain of Florida
(2009-07-16)
I examined microhabitat characteristics affecting the occupancy of wintering birds in a southeastern bottomland forest with repeated point counts at 186 sites. Models were derived a priori based on published literature and ...
Mining the TRAF6/P62 Interactome for Preferred Substrates and Target Ubiquitination Sites: Developing a “Code Hypothesis”
(2010-08-20)
Ubiquitination is the second most common protein modification studied in terms of biochemistry and cell physiology. It plays a central regulatory role in number of eukaryotic cellular and molecular processes. This three ...
Minnows and molecules: resolving the broad and fine-scale evolutionary patterns of Cypriniformes
(2017-04-21)
Cypriniformes (minnows, carps, loaches, and suckers) is the largest group of freshwater fishes in the world. Despite much attention, previous attempts to elucidate relationships using molecular and morphological characters ...
Mitochondrial behavior, morphology, and animal performance
(2021-10-18)
We have a limited understanding of the proximate mechanisms that are responsible for the development of variation in animal performance and life-history strategies. Many components of an organism’s successful life history–for ...
Mitochondrial Copper Transport in Saccharomyces cerevisiae
(2013-12-04)
Saccharomyces cerevisiae contains a copper pool within the mitochondrial matrix that is required for assembly and activity of cytochrome c oxidase. Matrix copper exists bound to an anionic, fluorescent molecule known as ...
Mitochondrial function and oxidative stress in response to induced reactive oxygen species and reproduction
(2018-07-24)
Mitochondria are pivotal in the survival of complex organisms, generating metabolic energy in all eukaryotic cells by breaking down carbohydrates, fatty acids, and protein from diet and converting them to ATP (adenosine ...
Modeling Complex Climate Change Effects on Fluctuating Populations of Fish Communities in the Northern Pacific Ocean
(2019-07-23)
The main purpose of this study was to bring new mathematical and statistical methods to the ecological community and highlight novel application of these methods to practical scientific questions. Deepwater marine systems ...
Molecular Ecology of Peromyscus polionotus
(2006-08-15)
Lowe et al. (2004) describes ecological genetics as “the investigation of the origin and maintenance of genetic variation within and between populations, which ultimately leads to adaptation and speciation.” Thus, to gain ...
Molecular Evolutionary and Functional Genomic Studies of Marshallia (Asteraceae) Utilizing Next Generation Sequencing Technology
(2015-05-06)
Several aspects of Marshallia (Asteraceae) genomics have been investigated using NGS
technologies. I have assembled and characterized Marshallia Clade III Cytokinin Response
Factor genes from DNA and RNA datasets. To ...
Molecular Interactions between phage and the catfish pathogen Edwardsiella ictaluri and Comparative Genomics of Epidemic strains of Aeromonas hydrophila
(2012-12-05)
Edwardsiella ictaluri causes Enteric Septicemia of Catfish (ESC) which is responsible for significant economic loss of the catfish aquaculture industry in the southeastern United States. A better diagnostic tool is required ...
Molecular Investigations of the Diversity of Freshwater Fishes across Three Continents
(2020-07-02)
Fishes are the most speciose vertebrates, and incredible diversity can be found within different groups of fish. Due to their physiological limitations, fish are confined to waters, and in freshwater fish, this is restricted ...
