Nutrient Enrichment Enhances Hidden Differences In Phenotype To Drive A Cryptic Plant Invasion, Christine Holdredge, Mark D. Bertness, Eric Von Wettberg, Brian R. Silliman

College of Agriculture and Life Sciences Faculty Publications

Many mechanisms of invasive species success have been elucidated, but those driving cryptic invasions of non-native genotypes remain least understood. In one of the most successful cryptic plant invasions in North America, we investigate the mechanisms underlying the displacement of native Phragmites australis by its Eurasian counterpart. Since invasive Phragmites' populations have been especially prolific along eutrophic shorelines, we conducted a two-year field experiment involving native and invasive genotypes that manipulated nutrient level and competitor identity (inter- and intra-genotypic competition) to assess their relative importance in driving the loss of native Phragmites. Inter-genotypic competition suppressed aboveground biomass of both native …

Understanding, Modeling And Valuing Ecosystem Services, Robert Costanza

Systems Science Friday Noon Seminar Series

Ecosystem services (ES) are the direct and indirect contributions of ecosystems (in combination with other inputs) to human well-being. An ES-based approach can assess the trade-offs inherent in managing humans embedded in ecological systems. Evaluating trade-offs requires both an understanding of the biophysical magnitudes of ES changes that result from human actions, as well as an understanding of their impact on human well-being, broadly conceived. This talk discusses the state of the art of ES assessment, valuation, and modeling, including the potential of integrated ecological economic modeling. Valuation is about assessing trade-offs – not necessarily about trades (exchanges) in markets …

The Amazon Frontier Of Land-Use Change: Croplands And Consequences For Greenhouse Gas Emissions, Gillian L. Galford, Jerry Melillo, John F. Mustard, Carlos E.P. Cerri, Carlos C. Cerri

Rubenstein School of Environment and Natural Resources Faculty Publications

The Brazilian Amazon is one of the most rapidly developing agricultural frontiers in the world. The authors assess changes in cropland area and the intensification of cropping in the Brazilian agricultural frontier state of Mato Grosso using remote sensing and develop a greenhouse gas emissions budget. The most common type of intensification in this region is a shift from single-to double-cropping patterns and associated changes in management, including increased fertilization. Using the enhanced vegetation index (EVI) from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor, the authors created a green-leaf phenology for 2001-06 that was temporally smoothed with a wavelet filter. …

Independent Study Project (ISP) Collection

Esta investigación trata sobe la seguridad energética de Chile, un concepto relativamente nuevo que tiene que ver con la capacidad de un país para garantizar un suministro energético, que permita el crecimiento económico y el desarrollo social. Actualmente, Chile se encuentra en una posición energética muy vulnerable. A pesar de su riqueza geográfica repleta de recursos energéticos renovables, carece de las fuentes de energía más importantes hoy día: el petróleo, el carbón y el gas natural. Por eso, para cumplir con una demanda creciente, tiene que importar entre el 70% y el 80% de su energía, dependiendo de pocos suministradores …

Balancing Limiting Factors & Economic Drivers For Sustainable Midwestern Us Agricultural Residue Feedstock Supplies, Wally W. Wilhelm, J. Richard Hess, Douglas L. Karlen, Jane M. F. Johnson, David J. Muth Jr., John M. Baker, Hero T. Gollany, Jeff M. Novak, Diane E. Scott, Gary E. Varvel

David J. Muth

Advanced biofuels will be developed using cellulosic feedstock rather than grain or oilseed crops that can also be used for food and feed. To be sustainable, these new agronomic production systems must be economically viable without degrading the soil and other natural resources. This review examines six agronomic factors that collectively define many of the limits and opportunities for harvesting crop residue for biofuel feedstock in the midwestern United States. The limiting factors include soil organic carbon, wind and water erosion, plant nutrient balance, soil water and temperature dynamics, soil compaction, and off-site environmental impacts. These are discussed in relationship …

Guano Exploitation In Madagascar, Christina Buliga

Independent Study Project (ISP) Collection

Agriculture in Madagascar continues to remain largely undeveloped. Out of the eighty percent of Malagasy individuals that live in rural areas an overwhelming sixty five percent practice subsistence agriculture. With respect to the country as a whole this means that out of Madagascar's 58.2 million hectares of available land only 5.2 percent (3 million hectares) are farmed. And out of these 3 million hectares only 67% are cultivated permanently and only 11% are fertilized.

While there are several reasons for why Madagascar’s agriculture has remained largely undeveloped and for why Madagascar continues to rely on imported crops to meet its …

Clean hydrogen production is highly desirable for future energy needs, making the understanding of molecular-level phenomena underlying photocatalytic hydrogen production both fundamentally and practically important. Water splitting on pure TiO₂ is inefficient, however, adding sacrificial methanol could significantly enhance the photocatalyzed H₂ production. Therefore, understanding the photochemistry of methanol on TiO₂ at the molecular level could provide important insights to its photocatalytic activity. Here, we report the first clear evidence of photocatalyzed splitting of methanol on TiO₂ derived from time-dependent two-photon photoemission (TD-2PPE) results in combination with scanning tunneling microscopy (STM). STM tip induced molecular manipulation …

Empirical Geographic Modeling Of Switchgrass Yields In The United States, Henriette I. Jager, Latha M. Baskaran, Craig C. Brandt, Ethan B. Davis

Dartmouth Scholarship

Switchgrass (Panicum virgatum L.) is a perennial grass native to the United States that has been studied as a sustainable source of biomass fuel. Although many field‐scale studies have examined the potential of this grass as a bioenergy crop, these studies have not been integrated. In this study, we present an empirical model for switchgrass yield and use this model to predict yield for the conterminous United States. We added environmental covariates to assembled yield data from field trials based on geographic location. We developed empirical models based on these data. The resulting empirical models, which account for spatial …
