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...

The methodology, implementation, and analysis of the isotopic composition of soil respired CO₂ in forest ecological research

Creator:

Kayler, Zachary Eric

Abstract:

Soils are the largest terrestrial pool of carbon, therefore it is critical to understand what controls soil carbon efflux to the atmosphere in light of current climate uncertainty. The primary efflux of carbon from soil is soil respiration which is typically categorized into autotrophic and heterotrophic respiration. These two components...

Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:

Barnard, Holly Rene

Abstract:

The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...
