Noise and signal transmission properties as agents of selection in the vibrational communication environment
(University of Missouri--Columbia, 2007)
Members of the Enchenopa binotata species complex (Hemiptera: Membracidae) are host-specific phytophagous insects that communicate by sending vibrations through their host plants. Successful communication depends on the ...
Identification, characterization and use of novel thermogenetic tools in drosophilia melanogaster
(University of Missouri--Columbia, 2019)
Extrinsic control of neural activity is necessary to decipher the neural mechanisms underlying behavior. Molecular tools that employ light (optogenetics) or temperature (thermogenetics) are primarily used for extrinsic ...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
Effective amphibian conservation requires an understanding of how populations respond to specific natural and anthropogenic factors. Chemical contaminants are among the known sources of acute and chronic stress and have ...
Mechanisms of the phototropic pathway
(University of Missouri--Columbia, 2018)
Plants are sessile organisms and therefore are limited in their ability to gather resources. Therefore, they have evolved several mechanisms that aid them in their quest to gather light, water and nutrients. One such ...
Mechanisms of photoreceptor mediated responses in photomorphogenesis and phototropism
(University of Missouri--Columbia, 2018)
Photoreceptor facilitated light perception provides plants with critical environmental information from which they can direct their growth. We investigated the early photomorphogenic responses in Glycine max and Glycine ...
Coupling, membrane conductance, and ion channel mRNA profiles in the establishment and maintenance of network activity in the crustacean cardiac ganglion
(University of Missouri--Columbia, 2021)
Neural networks produce critical rhythmic behaviors throughout an animal's lifespan, despite growth, differing environments, and changes in physiological state. This requires networks which balance stability in their ...
Regulation of plant development in Arabidopsis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The development of a complex organism, such as a plant, requires the function of multiple pathways that regulate various aspects of the developmental ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
The vital rates (e.g., survival, growth, and reproduction) of distinct life stages within a species are known to influence the growth and persistence of populations. As such, studies describing stage-specific vital rates, ...
Friends in high places : ecology of mycorrhizal associations in alpine plant communities
(University of Missouri--Columbia, 2010)
Mutualisms are ubiquitous in nature, yet these interactions often vary in strength and persistence. This variation raises the questions of what determines whether mutualisms persist or vanish, and how does variation in the ...
Developmental programming by xenoestrogens
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Xenoestrogens (XE) are chemicals in the environment that mimic the body's natural steroidal estrogens. Developmental exposure to XE may interfere with ...
