Microbial community dynamics associated with rhizosphere carbon flow

Creator:

Butler, Jessica L.

Abstract:

The cycling of root-deposited photo synthate (rhizodeposition) through the soil microbial biomass is widely recognized as a critical component of ecosystem functioning. Little is currently known about the flow of photosynthate through the microbial biomass however. My research goal was to examine if and how the flow of root-deposited photo...

Linking soluble C to microbial community composition and dynamics during decomposition of ¹³C-labeled ryegrass

Creator:

McMahon, Shawna K.

Abstract:

Ryegrass residue consists of three main C fractions: readily available soluble C, intermediately available cellulose and hemicellulose, and slowly available lignin. Changes in chemical composition during decomposition influence rate of degradation as well as composition of the microbial community involved. Use of ¹³C-labeled plant material coupled with analysis of phospholipid...

Variation in communities of ammonia-oxidizing and denitrifying bacteria in Fennoscandian boreal forest soils

Creator:

Ghimire, Rama D.

Abstract:

The objective of this study was to examine the variation among ammonia-oxidizing and denitrifying communities in soils of a natural Fennoscandian boreal forest and of a forest with a long history of fertilization with different levels of nitrogen (N), and to examine whether there are any changes in the microbial...

Litter controls of microbial community composition and function in forest soils

Creator:

Brant, Justin B.

Abstract:

Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...

Functional profiles of soil microbial communities in second-growth Douglas-fir forests of the Pacific Northwest

Creator:

McGinnis, Megan L.

Abstract:

Forests are one of the largest repositories of terrestrial C. Understanding factors that drive organic matter transformations and nutrient efflux from these systems is therefore highly important. Temperate forests are of particular significance due to the large fraction of C that is stored below ground in the soil. Characterizing nutrient...

Response of soil microbial communities and nitrogen cycling processes to changes in vegetation inputs

Creator:

Brewer, Elizabeth Ann

Abstract:

Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...

Soil community dynamics in sagebrush and cheatgrass-invaded ecosystems of the northern Great Basin

Creator:

DeCrappeo, Nicole M.

Abstract:

Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...

Evolution and ecology of the Ceanothus-Frankia symbiosis

Creator:

Jeong, Soon-Chun

Abstract:

The evolutionary relationship between Frankia and actinorhizal plants was evaluated by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia strains. Although the branching order...

The development and decline dynamics of two ectomycorrhizal fungal mat soil microbial communities in response to a reciprocal soil transfer experiment in old-growth Douglas-fir forests

Creator:

Cappellazzi, Jed E.

Abstract:

Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...

The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

Creator:

Boyle, Stephanie A.

Abstract:

The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...
