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, and the factors that shape...
The effects of metal contamination on larval white sturgeon in the upper Columbia River
(University of Missouri--Columbia, 2018)
in the upper Columbia River (UCR) face many of the same factors. White sturgeon in this system have been declining for decades due to a lack of recruitment to the population, despite evidence of spawning and early larval survival in the wild. Early life stage...
Brassicales to Brassica : integrating phylogenomics and population genomics
(University of Missouri--Columbia, 2020)
(e.g., kale) and are an important diet source for key minerals and elements. Ionomics, the measurement of the total elemental composition of an organism, allows for high throughput characterization of the levels of these elements at the same time...
Genetic and hormonal regulation of meristem initiation and maintenance pathways during maize vegetative and reproductive development
(University of Missouri--Columbia, 2021)
Plant development is driven by pools of undifferentiated stem cells called meristems. Meristems have two functions, to divide producing cells that will replenish the stem-cell niche, and cells that will differentiate into ...
