Tidal Influences on Bacterial and Phytoplankton Abundances and the Resulting Effects on Patterns of Dissolved Oxygen in the Skidaway River Estuary
… GA during the summer of 2005. A temporal study looked at changes in DO concentrations, Chlorophyll a concentrations, bacterial abundance, water depth, and salinity, every hour, for 26 hours, over both a neap and a spring tide. A spatial study looked at changes in the above variables at 5 …

Understanding key factors influencing habitat quality for the endangered fountain darter (Etheostoma fonticola) in the Comal River.
… herbivory and soil fertility experiment, and a spatial study of diel dissolved oxygen dynamics. Nutrient data were collected via water samples, nutrient diffusing substrata (NDS), sediment cores, and plant samples. The water samples and NDS results indicated a severe phosphorus limitation in the …

Microbial community dynamics in denitrifying biofilters receiving agricultural drainage
… employed two different approaches. First, in our spatial study we sampled one biofilter over the course of an afternoon in 2007 to determine how total and denitrifying bacterial communities varied by depth, transect, and position along a transect. Second, in our temporal study we sampled three …

Suicide in Hong Kong, 1981-1991 : a social and spatial analysis
This thesis is a social and spatial study of suicide in Hong Kong's three subregions: Hong Kong Island, Kowloon, and the New Territories for the period 1981-1991. The primary data used are official suicide statistics; these are supplemented by descriptive newspaper accounts of suicide. Over time, …

Biogeochemical investigations of methane-rich groundwaters in high Arctic glacial catchments
… rapid methane escape. Through an extensive spatial study of proglacial groundwater springs on Svalbard, groundwater systems within glaciated catchments are found to be bringing to the surface deep-seated methane gas that was previously trapped beneath glaciers and permafrost in the Arctic. …

Local food availability, diet and obesity: Development and empirical testing of a complex theory
… food outlets were examined in a cross-sectional spatial study of adults from the first wave of the UK Household Longitudinal Study (UKHLS). This analysis showed that again, regardless of individual SEP, the density of fast food outlets around the home was positively associated with away-from-home …

Setting Constraints on the Lunar Exosphere: A Comprehensive Analysis of Velocity Resolved Sodium and Potassium Line Profile Measurements
… years (2011 – 2017). These data are used to study the morphology and dynamics of the lunar exosphere. Additionally, potassium D1 (7698.9646 Å) is used as a complement to sodium. The two species approach, with sodium being the main attraction, provides constraints on the critical drivers of …

Constructing Frontier Villages: Human Habitation in the South Korean Borderlands after the Korean War
The inter-Korean border is often considered to be purely a politico-militaristic problem which renders the space of the border static, homogeneous, and empty of human habitation. However, a closer examination reveals a highly dynamic border full of discrepancies which is, in fact, inhabited by …
