Since the Clean Air Act Amendments of 1990, lakes in Maine and much of the Northeastern US have seen significant shifts in response to reduced atmospheric deposition as well as climate change. The organisms that inhabit lakes are susceptible to environmental change, but our unde…

This dissertation helps develop principles that integrate aspects of policy analysis into sustainability science. The three principal chapters are 2, 3, and 4. Through an application to multiple sources of drinking water in the presence of other ecological services, Chapter 2 il…
Sequence stratigraphic interpretations of subsurface data and stratigraphic modeling using SEDPAK program have generated insight into specific stratigraphic patterns of lacustrine rift basins, the southern Dead Sea and the Pannonian Basin in Hungary. In the Dead Sea, nine third-…
Large-scale climate modes are responsible for much of the Earth's climate variability. Despite the importance of these modes, we have limited understanding of how they vary on long timescales due to the short length of instrumental climate records. Fortunately, climate informati…
A limnological survey of 44 lakes in the Northern Niagara Escarpment region (south-western Ontario, Canada) highlighted differences between polymictic and dimictic hardwater lakes. Polymictic lakes were shallower, had higher water temperatures and dissolved organic carbon levels…
Accurately identifying fishes in their early life stages using morphology is challenging, time-consuming, and requires taxonomic expertise. Metabarcoding is a method that can be used to identify species in batch samples (Cruaud et al. 2017). Detection of early life stages of fis…
Red siliciclastics and evaporites of Permian Nippewalla Group in mid-continental US were deposited in western equatorial Pangea. Previous studies of these rocks record Permian air temperatures as high as 73 °C, saline lake waters with a pH as low as ~1, and sedimentology that sh…
Fishers (Pekania pennanti) were reintroduced in West Virginia in 1969 with no population wide genetic analysis ever having been conducted. Genetic analysis of reintroduced populations is vital to assess genetic diversity as an indicative of population viability. My objective was…
Remote sensing approaches to measuring inland water dynamics date back more than 50 years. These approaches rely on the unique spectral properties of different waterbodies to delineate surface extents and estimate optically active water quality parameters. Until recently, inland…
The conditions beneath glaciers and ice-sheets including the topography, hydrology, and geology are essential for understanding ice dynamics, interpreting ice-sheet history, and predicting ice-sheet retreat and sea-level-rise in response to a changing climate. Located in remote …
