Is Lac Anony Reaching Its Tipping Point? A Comparative Case Study Of The Traditional Fishery At The Village Of Antsovela, Corinne Haynes

Independent Study Project (ISP) Collection

Traditional fisheries are globally recognized as an important supplier of food resources. In fact, “small-scale fisheries provide over half the world’s wild-caught seafood” (Shester and Micheli, 2011). All around the southern tip of Madagascar, the traditional fishing industry acts as one of the most common livelihoods. The island nation contributes 120,000,000 tons of aquatic resources to the world supply each year, the majority of which is caught by traditional fishermen found in 1,250 rural villages all around the island. However, 80% of the catch is consumed locally, pinpointing the main goal of these traditional fishermen: to feed their families (RAZANOELISOA, …

Optimizing Spectral Indices And Chemometric Analysis Of Leaf Chemical Properties Using Radiative Transfer Modeling, Jean-Baptiste Féret, Christophe François, Anatoly A. Gitelson, Gregory P. Asner, Karen M. Barry, Cinzia Panigada, Stéphane Jacquemoud

School of Natural Resources: Faculty Publications

We used synthetic reflectance spectra generated by a radiative transfer model, PROSPECT-5, to develop statistical relationships between leaf optical and chemical properties, which were applied to experimental data without any readjustment. Four distinct synthetic datasets were tested: two unrealistic, uniform distributions and two normal distributions based on statistical properties drawn from a comprehensive experimental database. Two methods used in remote sensing to retrieve vegetation chemical composition, spectral indices and Partial Least Squares (PLS) regression, were trained both on the synthetic and experimental datasets, and validated against observations. Results are compared to a cross-validation process and model inversion applied to the …

Tracking Large Carnivore Dispersal Using Isotopic Clues In Claws: An Application To Cougars Across The Great Plains, Viviane Hénaux, Larkin A. Powell, Keith A. Hobson, Clayton Kent Nielsen, Michelle A. Larue

School of Natural Resources: Faculty Publications

1. Cougar (Puma concolor) populations, like other large carnivores, have increased during recent decades and may be recolonizing their former ranges in Midwestern North America. The dispersal routes taken by these animals from established populations are unknown and insight into these movements would facilitate their conservation and management.

2. We inferred the origin and migration route of four dispersing cougars using stable hydrogen (δD) and carbon (δ¹³C) isotope values along one of their claws. We compared isotopic variations within claws to regional and large-scale isoscapes of δD and δ¹³C values in prey species. Using …

Polarization Switching At The Nanoscale In Ferroelectric Copolymer Thin Films, R. V. Gaynutdinov, S. Mitko, S. G. Yudin, V. M. Fridkin, Stephen Ducharme

Stephen Ducharme Publications

The polarization switching kinetics were measured at the nanoscale in continuous thin films of a ferroelectric copolymer of vinylidene fluoride and trifluoroethylene. The dependence of the switching rate on voltage for a 54-nm thick film exhibits extrinsic nucleation and domain-growth type kinetics with no true threshold coercive field, and is qualitatively different from the behavior of an 18-nm thick film, which exhibits intrinsic switching kinetics, and a true threshold field. The results are consistent with studies of thin film capacitors of much larger area and with a recent refinement of the theory of the critical size for intrinsic switching.

Electrical Control Of Photoluminescence Wavelength From Semiconductor Quantum Dots In A Ferroelectric Polymer Matrix, Rafal Korlacki, Ravi F. Saraf, Stephen Ducharme

Stephen Ducharme Publications

We report controllable tuning of the room temperature photoluminescence band of CdSe semiconductor quantum dots embedded in thin films of ferroelectric copolymer of vinylidene fluoride and trifluoroethylene made by Langmuir-Blodgett deposition. The high breakdown strength of the polymer permits the application of electric fields of up to 400 MV/m and results in a shift in the photoluminescence peak by up to 9 nm, nearly half the fluorescence band width. Moreover, we found that at these high electric fields, the Stark effect exhibits unusual fourth power dependence.

Attosecond Streaking In The Low-Energy Region As A Probe Of Rescattering, Ming-Hui Xu, Liang-You Peng, Zheng Zhang, Qihuang Gong, Xiao-Min Tong, Evgeny A. Pronin, Anthony F. Starace

Anthony F. Starace Publications

The dynamics of low-energy photoelectrons (PEs) ionized by a single attosecond pulse in the presence of an intense infrared (IR) laser field is investigated. Whereas attosecond streaking usually involves momentum shifts of high-energy PEs, when PEs have low initial kinetic energies, the IR field can control the continuum-electron dynamics by inducing PE scattering from the residual ion. A semiclassical model is used to show that particular PE trajectories in the continuum involving electron-ion scattering explain the interference patterns exhibited in the low-energy PE spectrum. We confirm the effects of the trajectories by means of a full quantum simulation.

Analytic Energy Gradients In Combined Second Order Møller-Plesset Perturbation Theory And Conductorlike Polarizable Continuum Model Calculation, Dejun Si, Hui Li

Hui Li Publications

The analytic energy gradients in combined second order Møller-Plesset perturbation theory and conductor-like polarizable continuum model calculations are derived and implemented for spin-restricted closed shell (RMP2), Z-averaged spin-restricted open shell (ZAPT2), and spin-unrestricted open shell (UMP2) cases. Using these methods, the geometries of the S0 ground state and the T₁ state of three nucleobase pairs (guanine-cytosine, adenine-thymine, and adenine-uracil) in the gas phase and aqueous solution phase are optimized. It is found that in both the gas phase and the aqueous solution phase the hydrogen bonds in the T₁ state pairs are weakened by ∼1 kcal/mol as compared …

Variational Analysis Of Marginal Functions With Applications To Bilevel Programming, Boris S. Mordukhovich, Nguyen Mau Nam, Hung M. Phan

Mathematics Research Reports

This paper pursues a twofold goal. First to derive new results on generalized differentiation in variational analysis focusing mainly on a broad class of intrinsically nondifferentiable marginal/value functions. Then the results established in this direction apply to deriving necessary optimality conditions for the optimistic version of bilevel programs that occupy a remarkable place in optimization theory and its various applications. We obtain new sets of optimality conditions in both smooth and smooth settings of finite-dimensional and infinite-dimensional spaces.

Soil Organic Carbon Maintenance Requirements And Mineralizatyion Rate Constants: Site Specific Calculations, David Clay, Gregg Carlson, Sharon Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Over the past 100 years numerous studies have been conducted with the goal of quantifying the impact of management on carbon turnover. It is difficult to conduct a mechanistic evaluation of these studies because each study was conducted under unique soil, climatic, and management conditions. Techniques for directly comparing data from unique studies are needed. This paper: 1) demonstrates an approach for calculating SOC maintenance requirements and mineralization rate constants at different landscape positions; and 2) discusses techniques for conducting site- specific experiments and determining site-specific C sequestration potentials.

Photoinduced Electron Transfer In Naphthalimide-Pyridine Systems: Effect Of Proton Transfer On Charge Recombination Efficiencies, Pavel Kucheryavy, Renat Khatmullin, Ekaterina Mirzakulova, Dapeng Zhou, Ksenija D. Glusac

Chemistry Faculty Publications

We studied the effect of proton-coupled electron transfer on lifetimes of the charge-separated radicals produced upon light irradiation of the thiomethyl-naphthalimide donor SMe-NI-H in the presence of nitro-cyano-pyridine acceptor (NO(2)-CN-PYR). The dynamics of electron and proton transfer were studied using femtosecond pump-probe spectroscopy in the UV/vis range. We find that the photoinduced electron transfer between excited SMe-NI-H and NO(2)-CN-PYR occurs with a rate of 1.1 x 10(9) s(-1) to produce radical ions SMe-NI-H(center dot+) and NO(2)-CN-PYR(center dot-). These initially produced radical ions in a solvent cage do not undergo a proton transfer, possibly due to unfavorable geometry between N-H proton …

Noncanonical Hydrogen Bonding In Nucleic Acids. Benchmark Evaluation Of Key Base-Phosphate Interactions In Folded Rna Molecules Using Quantum-Chemical Calculations And Molecular Dynamics Simulations, Marie Zgarbova, Petr Jurecka, Pavel Banas, Michal Otyepka, Judit E. Sponer, Neocles B. Leontis, Craig L. Zirbel, Jiri Sponer

Chemistry Faculty Publications

RNA molecules are stabilized by a wide range of non canonical interactions that are not present in DNA. Among them, the recently classified base phosphate (BPh) interactions belong to the most important ones. Twelve percent of nucleotides in the ribosomal crystal structures are involved in BPh interactions. BPh interactions are highly conserved and provide major constraints on RNA sequence evolution. Here we provide assessment of the energetics of BPh interactions using MP2 computations extrapolated to the complete basis set of atomic orbitals and corrected for higher-order electron correlation effects. The reference computations are compared with DFT-D and DFT-D3 approaches, the …

Prototyping Method For Bragg­ Type Atom Interferometers, Brandon Benton, Michael Krygier, Jeffrey Heward, Mark Edwards, Charles W. Clark

Department of Physics and Astronomy Faculty Publications

We present a method for rapid prototyping of new Bragg ultra-cold atom interferometer (AI) designs useful for assessing the performance of such interferometers. The method simulates the overall effect on the condensate wave function in a given AI design using two separate elements. These are (1) modeling the effect of a Bragg pulse on the wave function and (2) approximating the evolution of the wave function during the intervals between the pulses. The actual sequence of these pulses and intervals is then followed to determine the approximate final wave function from which the interference pattern can be calculated. The exact …

Review Of Grass: In Search Of Human Habitat. By Joe C. Truett. Foreword By Harry W. Greene., Mary Ann Vinton

Great Plains Research: A Journal of Natural and Social Sciences

Much of the book is devoted to discussing the heavy human dependence on grasslands and whether this relationship can be maintained in company with grassland conservation. Can humans continue to use grasslands for food, fiber, and newer uses like biofuels and carbon banking while still sustaining the ecosystem? Many of us in academic ecology struggle with resolving perceived conflicts between conservation and human grassland use. In many cases, a "win-win" scenario exists in which, for example, the proper use of livestock grazing is perfectly compatible with a healthy grassland ecosystem. In other cases, such as conserving prairie dog populations, tensions …

Dr7a: Changes In Ecosystem Services And Migration In Low-Lying Coastal Areas Over The Next 50 Years, Robert Costanza, Ida Kubiszewski, Joe Roman, Paul Sutton

Institute for Sustainable Solutions Publications and Presentations

This paper examines the history and current status of ecosystem services in low-lying coastal areas (LLCAs), their potential changes because of wider environmental and social shifts, and the potential impacts of these changes on human migration. We synthesised information from a number of sources on the status and value of ecosystem services in LLCAs, including information about key ecosystems that are likely to be particularly vulnerable to environmental change. We created maps of ecosystem and human population changes in LLCAs and then estimated changes in ecosystem services. Estimating the impacts of these potential changes depends on the future scenario one …
