The Effect of Arctic River Hydrological Cycles on Arctic Ocean Circulation
… understanding the global oceanic salt and heat cycles and their response to climate variability. This thesis examines how one important aspect of Arctic Ocean circulation, the effect of freshwater inflow, may contribute to the variability of these cycles. The multiple roles that freshwater …

Stomatal acclimation to dynamic light: implications for photosynthesis and water use efficiency
… leaf to canopy levels, influencing carbon and hydrological cycles at global scales. Plant acclimation to growth light environment has been studied extensively; however, the majority of these studies have focused on constant light intensity and photo-acclimation, with few studies exploring the …

Simulating and quantifying land-surface biogeochemical, hydrological, and biogeophysical processes using the Community Land Model version 4
Carbon and nitrogen cycles, the energy cycle, and the hydrological cycle interact with each other; all are crucial to atmosphere–land studies. Carbon and nitrogen cycle from the atmosphere to vegetation communities and soil micro-organisms through their transformation in inorganic and organic …

The changing face of Andean peatlands: the effects of climate and human disturbance on ecosystem structure and function
… and reducing their ability to regulate the local hydrological cycles. To identify how rising temperatures and increasing human originated disturbances have peatlands, I studied the current vegetation patterns and related them to elevation, temperature and disturbance environmental gradients, …

Responses of a shallow-water ecosystem to the early Paleogene greenhouse environmental conditions : evolution of Larger Foraminifera and coral communities from the Northern Tethys
… This event initiated global warming, changes in hydrological cycles, biotic extinction and migrations. A recently proposed hypothesis concerning changes in marine ecosystems suggests that this global warming strongly influenced the shallow-water biosphere, triggering extinctions and turnover in …

Biogeochemical Consequences of Hydrologic Conditions in a Tropical Montane Rain Forest in Ecuador
Tropical montane forests regulate the hydrological cycles of high-elevation areas being an important service for the local population. The objectives of my work were (1) to determine the major hydrological flow paths, (2) to quantify concentrations of dissolved organic C and organic and inorganic …

Investigating groundwater derived nutrient fluxes within Tauranga harbour, New Zealand
… that this process is important in global hydrological and biogeochemical cycles. Due to the large coastline to land area ratio, steep topography, permeable sediments and high rainfall, oceanic islands, may have the potential for disproportionally large SGD fluxes into the ocean compared to …

Tracing hydrological millennial-scale cycles in the late Quaternary of the Cariaco Basin and the southern Gulf of Cádiz using coccoliths and dinoflagellate cysts
… tropical to subtropical regions are coupled to hydrological changes. The reconstruction of these hydrological changes during rapid late Quaternary climate oscillations is crucial for climate change study. The present study demonstrates that coccoliths and dinoflagellate cysts are very useful as …
