Lichen Biomonitoring from Valley to Alpine in Central and Southern California

Creator:

Kovasi, Adrienne I.

Abstract:

In the mountains of central and southern California, high elevation wilderness areas lack epiphytic lichens that can be used to inform us about atmospheric deposition in multiple ways. Epiphytic lichens are capable of accumulating elements proportionally to the local atmospheric concentration, establishing them as commonly used biomonitor of key elements....

Masters Thesis
Spatial Variation in Ecosystem Carbon Stocks and Emissions Resulting from Land-use Conversion: Two Studies in Mangrove Forests of the Dominican Republic

Creator:

Giovannoni, Leila R.

Abstract:

Mangrove forests store more organic carbon across ecosystem carbon pools than most other coastal and forested ecosystems, and are subject to high global rates of deforestation. For these reasons, they are recognized as prime candidates for inclusion in climate change mitigation strategies. However, the ecological drivers of regional and micro-scale...

Detrital Influences on Soil Carbon Stabilization in Wet Temperate Forest Soils

Creator:

Pierson, Derek N.

Abstract:

Soils, with their potential to store and stabilize carbon (C), are an essential resource for sustaining forest productivity, as well as for efforts to reduce atmospheric C concentrations. Protecting existing soil C and harnessing the sequestration potential of our soils require an improved understanding of the processes through which soil...

Dissertation
Stream Temperature and Autotrophic Responses to Riparian Canopy Gaps Over Forested Headwater Streams

Creator:

Swartz, Allison

Abstract:

Across much of North America, legacies of historic and contemporary timber harvest have created a landscape dominated by regenerating forest stands in the early to middle stages of development. Most streamside forests are currently in the stem-exclusion phase of stand development and these closed canopies shade the forest understory and...

Masters Thesis
Environmental Stressors Influence Fabaceae Seedling Development

Creator:

Gerber, Kaitlin A.

Abstract:

Sites in need of restoration typically have one or more environmental factors that limit seedling establishment; identifying ecophysiological responses to environmental stressors can be advantageous in growing seedlings able to overcome such constraints on survival. To maximize survival after outplanting, seedlings should be grown in a manner that considers both...

Masters Thesis
Carbon Dynamics Associated with Land Cover Change in Tropical Mangrove Ecosystems of the Mahakam Delta, East Kalimantan, Indonesia

Creator:

Arifanti, Virni B.

Abstract:

The Mahakam Delta which was once among the largest mangrove forests in Indonesia, has been subjected to dramatic changes in structure and function due to massive shifts from mangrove forest to shrimp ponds and oil and gas development. To understand the impacts of mangrove loss to the greenhouse gas (GHG)...

Dissertation
Interactions between nitrogen, phosphorus, and molybdenum in forest soils and cyanobacterial lichen in the Oregon Coast Range

Creator:

Marks, Jade A.

Abstract:

Molybdenum is an essential component of biogeochemical cycling, most notably as a component of the nitrogenase enzyme used in biological nitrogen (N) fixation. While the important role of phosphorus (P) in limiting N fixation in ecosystems has been well documented, occurrence and prevalence of molybdenum (Mo) limitation is largely unknown....

Masters Thesis
Distinguishing biological and physical controls on soil respiration

Creator:

Phillips, Claire L.

Abstract:

Soil respiration, or the combined CO₂ emissions from roots and soil microorganisms, constitutes one of the largest losses of carbon (C) from terrestrial ecosystems. The major drivers of soil respiration, which include soil moisture, temperature, and substrate quality, have been known for some time. Nevertheless, correlations between these drivers and...

Assessing the sustainability of management practices for planted forests across an environmental gradient in New Zealand

Creator:

Kiyvyra, Alicia L.

Abstract:

Sustainable management of planted forests requires maintenance of soil function to promote 1) root growth; 2) storage and cycling of water and nutrients; 3) optimal gas exchange; and 4) biological activity. Soil quality measurements can be used to monitor short- and long-term changes in these soil functions, allowing managers to...
