Molecular Evolution in the Mountains: Genetic Affinity and the Environment led to Adaptive Variation in the American Pika (Ochotona princeps)
… is discontinuously distributed in high elevation and montane regions across western North America, where isolated lineages have potentially evolved along divergent trajectories since the mid-Pleistocene. <em>Ochotona princeps</em> encounters cold temperatures, hypoxia, and dietary …

A DNS capability for obtaining underwater light field and retrieving upper ocean conditions via in-water light measurements
Predicting the ocean surface conditions (surface elevation, temperature, wind speed, etc.) becomes more and more important for both real life and military applications. This thesis presents a direct numerical simulation (DNS) capability of solving complicated natural light field patterns in the …

SPATIAL VARIABILITY IN SPECIES COMPOSITION IN NEOTROPICAL MONTANE TREE COMMUNITIES
… diversity, and floristic composition across the elevational gradient and at tree line. Thirty –six 0.1–ha tree plots were installed (1) along three different elevational transects in tropical montane cloud forest (TMCF) between 1500 and 3600 m and (2) across a ∼ 40 km landscape …

The changing face of Andean peatlands: the effects of climate and human disturbance on ecosystem structure and function
… of new plant growth each year. Rising temperatures and increasing nutrient inputs from human activities can accelerate decomposition rates in the soil transforming peatlands from sinks to sources of carbon, and reducing their ability to regulate the local hydrological cycles. To …

Ecologic factors and tick-borne relapsing fever in the western United States: county and zip code analyses
… health departments. Ecologic factors, including elevation, precipitation, average minimum temperature, average maximum temperature, and land cover, in these areas were compared by frequency analysis and logistic regression analyses. The occurrence of TBRF was associated with elevation, …

Thermodynamics and Kinetics of Carbon Dioxide Corrosion of Mild Steel at Elevated Temperatures
… investigated. Nevertheless, research on high temperature CO<sub>2</sub> corrosion has been rarely conducted, and its mechanisms remain unclear. Therefore, it is important to complete an in-depth study of CO<sub>2</sub> corrosion of mild steel at high temperature. The entire scope of this Ph.D. …

Freshwater fish in the Waikato region : an evaluation of novel standardised data and drivers of fish distribution and abundance : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Ecology at Massey University Manawatū, New Zealand
… model identified drivers of variation. Distance, elevation, temperature, and slope frequently ranked high as drivers of native fish distribution and abundance. Longfin eels and redfin bullies appear to be excluded from areas of intensive agriculture throughout the central Waikato with redfin …
