Assessment of the microbiome associated with endangered orchids
(University of Missouri--Columbia, 2018)The Orchidaceae (orchid family) is perhaps the most speciose group of flowering plants with approximately 25,000 described species and many thousands of hybrids. While certain mycorrhizal fungi are required for orchids to ... -
The ecological roles of amphibians and subsidies in ponds
(University of Missouri--Columbia, 2018)Freshwater ponds are often underappreciated landscape features, despite the fact they comprise a major portion of all freshwater ecosystems. Ponds support diverse food webs and species not found in other habitat types. ... -
The effects of metal contamination on larval white sturgeon in the upper Columbia River
(University of Missouri--Columbia, 2018)Sturgeon populations are imperiled worldwide. Declines are attributed to many factors including habitat degradation and alteration, overexploitation, and contamination. In North America, white sturgeon (Acipenser transmontanus) ... -
The evolution of complex calls In meadow Katydids
(University of Missouri--Columbia, 2018)Meadow Katydids (genera Orchelimum and Conocephalus) are a specious group often are found in habitats with several species within the group living in sympatry. They produce complex calls with two distinct phrases, "buzzing" ... -
Genetic diversity and distribution of the ringed salamander (ambystoma annulatum) across multiple spatial scales
(University of Missouri--Columbia, 2018)Species distributions are governed by a complex suite of abiotic and biotic interactions that govern movement of individuals and are variable through time and space. These dynamic processes, such as shifts in temperature ... -
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 ... -
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 ... -
Plasticity of neurons in mouse major pelvic ganglia in response to loos of physiological input in cases of nerve injury and spinal cord injury
(University of Missouri--Columbia, 2018)Autonomic dysfunctions present significant effects on day to day functions of spinal cord-injured patients. Most people with spinal cord injury (SCI) reported a desire to recover autonomic functions such as bladder and ... -
PopZ and FtsZ coordinate polar growth termination and cell division in Agrobacterium tumefaciens
(University of Missouri--Columbia, 2018)Understanding how bacterial cells expand their cell walls is an important question with relevance to development of antibiotics. While many studies have focused on the regulation of bacterial elongation utilizing lateral ... -
Roles for the adhension molecule Contactin2 in the development and function of neural circuits in zebrafish
(University of Missouri--Columbia, 2018)Neuronal migration and axon guidance are critical developmental processes that are essential for establishing functional neural circuits underlying complex cognitive and motor functions. Precise neuronal migration and axon ... -
Understanding the effects of maternal undernutrition in early gestation on placental development in late gestation
(University of Missouri--Columbia, 2018)Chronic diseases such as cardiovascular disease and diabetes are on the rise among the U.S. population. Heart Disease is the leading cause of death in the US and is responsible 610,000 deaths per year. A suite of risk ...
