Fast-Decaying Plant Litter Enhances Soil Carbon In Temperate Forests But Not Through Microbial Physiological Traits, Matthew E. Craig, Kevin M. Geyer, Katilyn V. Beidler, Edward R. Brzostek, Serita D. Frey, A. Stuart Grandy, Chao Liang, Richard P. Phillips

Faculty Publications

Conceptual and empirical advances in soil biogeochemistry have challenged long-held assumptions about the role of soil micro-organisms in soil organic carbon (SOC) dynamics; yet, rigorous tests of emerging concepts remain sparse. Recent hypotheses suggest that microbial necromass production links plant inputs to SOC accumulation, with high-quality (i.e., rapidly decomposing) plant litter promoting microbial carbon use efficiency, growth, and turnover leading to more mineral stabilization of necromass. We test this hypothesis experimentally and with observations across six eastern US forests, using stable isotopes to measure microbial traits and SOC dynamics. Here we show, in both studies, that microbial growth, efficiency, and …

Microbial Feedbacks On Soil Organic Matter Dynamics Underlying The Legacy Effect Of Diversified Cropping Systems, Maria Mooshammer, A. Stuart Grandy, Francisco Calderon, Steve Culman, Bill Deen, Rhae A. Drijber, Kari Dunfield, Virginia L. Jin, R. Michael Lehman, Shannon L. Osborne, Marty Schmer, Timothy M. Bowles

Faculty Publications

Crop rotations have well-known aboveground and belowground benefits. At regional to continental scales, the unifying mechanisms of how diversified rotations alter soil organic matter (SOM) dynamics have not been demonstrated. We assessed how increasing crop rotational diversity across a soil-climate gradient affected the integrated response of SOM chemistry, microbial community composition, and its enzymatic potential to degrade SOM. Agroecosystems with the same crop rotational diversity (all sampled during the corn phase) shared similarities in molecular SOM patterns with a strong microbial signature, pointing to common transformation processes. Differences in SOM chemistry between rotations were mainly characterized by shifts in microbial …

Dominance Of Diffusive Methane Emissions From Lowland Headwater Streams Promotes Oxidation And Isotopic Enrichment, Andrew L. Robison, Wilfred M. Wollheim, Clarice R. Perryman, Annie R. Cotter, Jessica E. Mackay, Ruth K. Varner, Paige Clarizia, Jessica G. Ernakovich

Faculty Publications

Inland waters are the largest natural source of methane (CH4) to the atmosphere, yet the contribution from small streams to this flux is not clearly defined. To fully understand CH4 emissions from streams and rivers, we must consider the relative importance of CH4 emission pathways, the prominence of microbially-mediated production and oxidation of CH4, and the isotopic signature of emitted CH4. Here, we construct a complete CH4 emission budgets for four lowland headwater streams by quantifying diffusive CH4 emissions and comparing them to previously published rates of ebullitive emissions. We also examine the isotopic composition of CH4 along with the …

Reassessing The Role Of Anthropogenic Climate Change In The Extinction Of Silphium, Paul Pollaro, Paul Robertson

Faculty Publications

The famed ancient herb, known to the Romans as silphium (Greeksilphion), is widely regarded as the first recorded instance of human-induced species extinction. Modern scholars have largely credited direct exploitation (e.g., over-harvesting; over-grazing) as the primary cause of silphium's extinction, due to an overwhelming demand for the plant in ancient times. Recent research has revealed strict cold-stratification requirements for the germination of silphium's closest living relatives, revealing the likelihood that silphium shared these same germination requirements. Documented environmental changes in ancient Cyrenaica (e.g., widespread deforestation; cropland expansion) likely resulted in accelerated rates of desertification throughout the region as well as …

Future Of Winter In Northeastern North America: Climate Indicators Portray Warming And Snow Loss That Will Impact Ecosystems And Communities, Elizabeth Burakowski, Alix Contosta, Danielle Grogan, Sarah Nelson, Sarah Garlick, Nora Casson

Faculty Publications

Winters in northeastern North America have warmed faster than summers, with impacts on ecosystems and society. Global climate models (GCMs) indicate that winters will continue to warm and lose snow in the future, but uncertainty remains regarding the magnitude of warming. Here, we project future trends in winter indicators under lower and higher climate-warming scenarios based on emission levels across northeastern North America at a fine spatial scale (1/16°) relevant to climate-related decision making. Under both climate scenarios, winters continue to warm with coincident increases in days above freezing, decreases in days with snow cover, and fewer nights below freezing. …

Crop Rotational Complexity Affects Plant-Soil Nitrogen Cycling During Water Deficit, Timothy M. Bowles, Andrea Jilling, Karen Moran-Rivera, Jorg Schnecker, A. Stuart Grandy

Faculty Publications

One of the biggest environmental challenges facing agriculture is how to both supply and retain nitrogen (N), especially as precipitation becomes more variable with climate change. We used a greenhouse experiment to assess how contrasting histories of crop rotational complexity affect plant-soil-microbe interactions that govern N processes, including during water stress. With higher levels of carbon and N cycling hydrolytic enzymes, higher mineral-associated organic matter N concentrations, and an altered microbial community, soils from the most complex rotation enabled 80% more corn N uptake under two moisture regimes, compared to soil from monoculture corn. Higher levels of plant N likely …

Faculty Publications

Biomass burning (BB) events are occurring globally with increasing frequency, and their emissions are having more impacts on human health and climate. Large ash particles are recognized as a BB product with major influences on soil and water environments. However, fine-ash particles, which have diameters smaller than several microns and characteristic morphologies and compositions (mainly Ca and Mg carbonates), have not yet been explicitly considered as a major BB aerosol component either in field observations or climate models. This study measured BB aerosol samples using transmission electron microscopy (TEM) and ion chromatography during the Fire Influence on Regional to Global …

The Renewal Workshop: Consumer Considerations In A Global Supply Chain, Aparna Sundar, Wendy G. Pothier, Bruce Pfeiffer, Leyi Lei

Faculty Publications

In responding to the international need for a circular economy, The Renewal Workshop (TRW) expanded its operations by opening a second factory in Amsterdam, The Netherlands in 2019. Much of the success of TRW, since its inception in Oregon in 2016, was due to its innovation in supply chain process. TRW incorporated novel solutions of renewing damaged apparel and upcycling overstock products, and consulted brands on ways to design for deconstruction. As the effectiveness of TRW becomes evident and demand grows internationally, it is facing some unexpected challenges. Students will need to reconsider positioning and communication strategy of The Renewal …

Ineffective Assistance Of Counsel In Dna Cases: A Re-Appraisal Of The Effectiveness Of Strickland V. Washington Judges, Albert E. Scherr

Law Faculty Scholarship

The advent of forensic DNA evidence has made possible the prosecution of many crimes that would otherwise be un-prosecutable or that would have been weak cases, if prosecuted. At the same time, forensic DNA technology has raised very substantial concerns about the reliability of evidence previously viewed as the gold standard in proof Wrongful convictions by the Innocence Project and others have established that eyewitness misidentifications, false confessions, bad forensics and mistaken guilty pleas occur. The much lesser known but still very troubling concern is with the performance of defense counsel in cases in which the prosecution has forensic DNA …
