RSS 1.0Division of Biological Sciences (MU)
The Division of Biological Sciences at MU offers a unique integration of world-class research, award-winning graduate and undergraduate training, and outstanding community outreach. Our faculty research programs include the acquisition of new knowledge through basic research, and coordinated translational research to improve human health, our food supply, and our environment. Our graduate training programs emphasize the excitement of discovery and the development of individual creativity and critical reasoning skills, with graduate mentors who are experts at the frontiers of their field. In undergraduate education, as in our graduate programs, we emphasize the excitement of discovery and the development of individual creativity and critical reasoning skills, providing an excellent foundation for advanced study or direct entry into the workplace. Because science exposure in the pre-college years is critical to the development of both scientists and informed citizens, we also offer special outreach programs for secondary school science teachers and their students in Missouri.

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 ... -
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 ... -
Morphological and physiological responses of two savanna tree species to grass competiton
(University of Missouri--Columbia, 2016)Interactions between trees and grasses in savannas have been studies quite extensively, yet the mechanism by which trees and grasses coexist is still not completely clear. The strength of tree-grass interactions can ... -

The spatial dimensions of savanna fire ecology in Kruger National Park, South Africa
(University of Missouri--Columbia, 2015)Savannas are thought to be bistable with forests potentially occurring above ~650 mm / yr of Mean Annual Precipitation (MAP) due to the limiting effects of fire on tree cover. This is predicated on two assumptions: 1) fires ... -
Call synchrony and the evolutionary origins of leader preference in Neoconocephalus ensiger katydids
(University of Missouri--Columbia, 2016)Many species of acoustically communicating insects and anurans display a female preference for males producing their calls just ahead of those of their neighbors. The evolutionary origin of these preferences is unclear. ... -
A mechanistic exploration of signaling crosstalk regulating light responses, growth and immunity in Arabidopsis
(University of Missouri--Columbia, 2016)For decades, processes in molecular biology have typically been studied in isolation, and for very good reason since only through carefully crafted experiments under precise conditions have discoveries to date been possible. ... -
Nesting and postfledging ecology of Neotropical migrant songbirds in Missouri forest fragments
(University of Missouri--Columbia, 2016)The postfledging period, between leaving the nest and the first migration, is a critical time for migrant songbirds, encompassing an interval of high mortality for the majority of species studied to date. Several species ... -
The role of heme oxygenase in metastatic melanoma tumorigenicity
(University of Missouri--Columbia, 2015)Reactive oxygen species (ROS) are highly reactive, tumorigenic molecules. In response to ROS accumulation, or oxidative stress, the transcription factor Nrf2 promotes expression by binding antioxidant response elements ... -
Therapeutic and chemopreventive potential of luteolin against growth and metastasis of breast cancer
(University of Missouri--Columbia, 2015)Breast cancer is the second leading cause of cancer-related death in older women. Many postmenopausal women undergo hormone replacement therapy (HRT) to alleviate the symptoms of menopause. Recent studies implicate the ... -
Changes in properties of lamprey reticulospinal neurons following spinal cord injury
(University of Missouri--Columbia, 2015)The lamprey is one of the most ancient vertebrates, sharing many of basic characteristics of the brain and spinal cord with higher, more evolved vertebrates such as mammals. However, unlike humans and other higher vertebrates, ... -
Unconventional oil and gas extraction as a novel source of endocrine disrupting chemicals to water and the potential for adverse human and animal health outcomes
(University of Missouri--Columbia, 2015)The proper and unimpeded function of hormones is essential for normal development, maturation, and prevention of chronic diseases. Endocrine disrupting chemicals (EDCs) are exogenous chemicals that have been found to disrupt ... -
Association of force plate and body-mounted inertial sensor measures for determination of hind limb lameness in horses
(University of Missouri--Columbia, 2015)The purpose of this study was to investigate the association between inertial sensor and stationary force plate measures of hind limb lameness. 21 adult horses that were either sound or had mild hind limb lameness were ... -
Examining the role of Gbx1 in spinal cord development and its contribution to mammalian locomotion
(University of Missouri--Columbia, 2015)Animals explore their environment through locomotion. Motion is largely generated by the activity of neurons in the spinal cord. Genes expressed during embryonic development are essential for the formation of connections ... -
Localization mechanisms of small plant-dwelling insects
(University of Missouri--Columbia, 2015)Movement is the basis of animal ecology, and understanding the causes and consequences of animal movement is a major goal of ecological research. Movement decisions involve an integrated process of sensory input and ... -
Molecular dissection of meiotic silencing by unpaired DNA
(University of Missouri--Columbia, 2015)Meiotic silencing by unpaired DNA (MSUD) is a genome surveillance mechanism that uses RNAi to protect against genetic parasites such as retrotransposons and viruses. This is accomplished by scanning the genome for DNA ... -
Molecular dissection of a genome defense pathway in Neurospora crassa
(University of Missouri--Columbia, 2015)Meiotic silencing by unpaired DNA (MSUD) is an RNA interference (RNAi) pathway in Neurospora crassa that detects genes without a homologous partner and silences them for the duration of sexual development. In this study, ... -
