Blue light- and ubiquitin-dependent influence on phototropin 1 abundance and movement at the plasma membrane
(University of Missouri--Columbia, 2016)Phototropism is the ability of a plant to bend in response to directional light. he shoot of a plant exhibits a positive response bending toward the light to optimize solar collection. The roots exhibit a negative response ... -
Call synchrony and the evolutionary origins of leader preference in Neoconocephalus ensiger katydids /
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Many species of acoustically communicating insects and anurans display a female preference for males producing their calls just ahead of those of their ... -
Curcumin regulates transcription in Dictyostelium discoideum
(University of Missouri--Columbia, 2016)Botanicals are widely used as dietary supplements and for the prevention and treatment of a myriad of diseases ranging from the common cold to depression. One in four Americans uses a botanical as part of their primary ... -
Effects of phenotype- and condition-dependent factors on juvenile dispersal of the ringed salamander (Ambystoma annulatum)
(University of Missouri--Columbia, 2016)Dispersal is the movement of individuals from their natal population to a different breeding population. Long distance dispersal movements are rare, with most individuals staying within their natal population (hereafter ... -
Exploring ion channel mechanisms : from toxin-based tools to computational methods /
(University of Missouri--Columbia, 2016)Ion channels are the building blocks of cellular excitability, controlling the most basic functions necessary for life to the most complex behaviors. The research presented here addresses questions about the mechanisms by ... -
Homeostatic compensation and neuromodulation maintain synchronized motor neuron activity in the crustacean cardiac ganglion
(University of Missouri--Columbia, 2016)Animals rely on the nervous system to produce appropriate behavior throughout their lives. In sending commands to the musculature for rhythmic motor behaviors such as breathing or walking, neural networks must be stable ... -
A mechanistic exploration of signaling crosstalk regulating light responses, growth and immunity in Arabidopsis
(University of Missouri--Columbia, 2016)Using the model plant Arabidopsis thaliana, our research focuses on the intersection between pathogen defense and photobiology. PIXL is a putative resistance protein found to be an interactor of phototropin1. Mutants lacking ... -
Nesting and postfledging ecology of Neotropical migrant songbirds in Missouri forest fragments
(University of Missouri--Columbia, 2016)The postfledging period, after fledging and before migration, is a critical stage for Neotropical migrant songbirds. The postfledging period encompasses an interval of high mortality that can greatly affect population ... -
Peripheral nervous system alterations in disease and injury
(University of Missouri--Columbia, 2016)Charcot-Marie-Tooth (CMT) is the most common inherited neuropathy of the PNS affecting approximately 2.8 million people. CMT type 2E, an axonal form of CMT, has been linked to mutations in the neurofilament light gene ... -
Predation and competition among larval salamanders : the influence of density dependence, phenology, food web structure and habitat complexity
(University of Missouri--Columbia, 2016)The influence of biotic and abiotic factors on species interactions and overall community structure has long interested ecologists. Despite a legacy of interest, there is still ambiguity into the role of biotic and abiotic ... -
Restoration at the roots : mycorrhizal interactions and habitat restoration in glades and prairies
(University of Missouri--Columbia, 2016)In a fragmented landscape, species diversity, richness, and abundance are largely determined by habitat characteristics such as patch size, successional age, isolation, and edge effects. Habitat patch characteristics may ...
