Revisiting The Carbon–Biodiversity Connection, John Gamon

School of Natural Resources: Faculty Publications

This article is a Commentary on Schuldt et al., https://doi.org/10.1111/gcb.16697

The link between biodiversity and ecosystem function has long been a subject of intense interest and debate among biologists, going back to the time of Charles Darwin, whose ideas on species interactions presaged subsequent discussions of biodiversity and ecosystem function (Peterson et al., 1998). Since then, many considerations of community diversity have centered on the importance of species or functional diversity for maintaining system resilience in the face of disturbance, analogous to the way that interwoven threads maintain the function and integrity of fabric. While our language, concepts, and methods …

Connecting Distinct Realms Along Multiple Dimensions: A Meta-Ecosystem Resilience Perspective, David G. Angeler, Jani Heino, Juan Rubio-Ríos, J. Jesús Casas

School of Natural Resources: Faculty Publications

Resilience research is central to confront the sustainability challenges to ecosystems and human societies in a rapidly changing world. Given that social-ecological problems span the entire Earth system, there is a critical need for resilience models that account for the connectivity across intricately linked ecosystems (i.e., freshwater, marine, terrestrial, atmosphere). We present a resilience perspective of meta-ecosystems that are connected through the flow of biota, matter and energy within and across aquatic and terrestrial realms, and the atmosphere. We demonstrate ecological resilience sensu Holling using aquatic-terrestrial linkages and riparian ecosystems more generally. A discussion of applications in riparian ecology and …

Impacts Of Standards-Based Grading And Alternate Grading Strategies On Student Success, Brian Remington

All Electronic Theses and Dissertations

Standards-based grading has changed how schools have graded its students for the past few years. Under standards-based grading students receive several grades for each benchmark skill that the student displays their knowledge of. This is a huge departure from what I have always known through my own education. For my Master's thesis, I reviewed the recent literature around standards-based grading and other grading experiments. I wanted to see what the effect of the changes have been, and more importantly what advice can be drawn from the recent research literature on the subject. Overall, teachers' and students' experiences with alternative grading …

Variable-Dependent Partial Dimension Reduction, Lu Li, Kai Tan, Xuerong Meggie Wen, Zhou Yu

Mathematics and Statistics Faculty Research & Creative Works

Sufficient dimension reduction reduces the dimension of a regression model without loss of information by replacing the original predictor with its lower-dimensional linear combinations. Partial (sufficient) dimension reduction arises when the predictors naturally fall into two sets X and W, and pursues a partial dimension reduction of X. Though partial dimension reduction is a very general problem, only very few research results are available when W is continuous. To the best of our knowledge, none can deal with the situation where the reduced lower-dimensional subspace of X varies with W. To address such issue, we in this paper propose a …

Machine Learning Approach For Automated Detection Of Irregular Walking Surfaces For Walkability Assessment With Wearable Sensor, Hui R. Ng, Isidore Sossa, Yunwoo Nam, Jong-Hoon Youn

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The walkability of a neighborhood impacts public health and leads to economic and environmental benefits. The condition of sidewalks is a significant indicator of a walkable neighborhood as it supports and encourages pedestrian travel and physical activity. However, common sidewalk assessment practices are subjective, inefficient, and ineffective. Current alternate methods for objective and automated assessment of sidewalk surfaces do not consider pedestrians’ physiological responses. We developed a novel classification framework for the detection of irregular walking surfaces that uses a machine learning approach to analyze gait parameters extracted from a single wearable accelerometer. We also identified the most suitable location …

Globally Scalable Approach To Estimate Net Ecosystem Exchange Based On Remote Sensing, Meteorological Data, And Direct Measurements Of Eddy Covariance Sites, Ruslan Zhuravlev, Andrey Dara, André Luís Diniz Dos Santos, Oleg Demidov, George Burba

Daugherty Water for Food Global Institute: Faculty Publications

Despite a rapid development of Nature-Based Solutions (NBS) for carbon removal in recent years, the methods for evaluating NBS still have certain gaps. We propose an approach based on a combination of remote sensing data and meteorological variables to reconstruct the spatiotemporal variation of net ecosystem exchange from eddy-covariance stations. A Lagrangian particle dispersion model was used for upscaling satellite images and flux towers. We trained data-driven models based on kernel methods separately for each selected land-cover class. The results suggest that the proposed approach to quantifying carbon exchange on a medium-to-large scale by blending eddy covariance flux data with …

Role Of Social Determinants Of Health In Differential Respiratory Exposure And Health Outcomes Among Children, Jagadeesh Puvvula, Jill A. Poole, Yeongjin Gwon, Eleanor G. Rogan, Jesse E. Bell

Daugherty Water for Food Global Institute: Faculty Publications

Background Attributes defining the Social Determinants of Health (SDoH) are associated with disproportionate exposures to environmental hazards and differential health outcomes among communities. The dynamics between SDoH, disproportionate environmental exposures, and differential health outcomes are often specific to micro-geographic areas.

Methods This study focused on children less than 20 years of age who lived in Douglas County, Nebraska, during 2016–2019. To assess the role of SDoH in differential exposures, we evaluated the association between SDoH metrics and criteria pollutant concentrations and the association between SDoH and pediatric asthma exacerbations to quantify the role of SDoH in differential pediatric asthma outcomes. …

Improving Cancer Classification With Domain Adaptation Techniques, Juliana Veira

Yale Medicine Thesis Digital Library

Background: As the quantity and complexity of oncological data continue to increase, machine learning (ML) has become an important tool in helping clinicians better understand malignancies and provide personalized care. Diagnostic image analysis, in particular, has benefited from the advent of ML methods to improve image classification and generate prognostic information from imaging collected in routine clinical practice [1-3]. Deep learning, a subset of ML, has especially achieved remarkable performance in medical imaging, including segmentation [4, 5], object detection, classification [6], and diagnosis [7].

Despite the notable success of deep learning computer vision models on oncologic imaging data, recent studies …

Magnetotelluric Investigations Over Geothermal Provinces Of India: An Overview, Prabhala Bhakhara Venkata Subbarao, Pachigolla Venkata Vijaya Kumar, Dornadula Chandrasekharam, Vasu Deshmukh, Ajay Kishore Singh

Turkish Journal of Earth Sciences

Magnetotelluric (MT) and audio-magnetotelluric (AMT) studies are sensitive to the geothermal fluids filling the faults and/ or fracture zones of the geothermal system. In India, MT/AMT studies have been carried out in NW Himalayas, central, eastern, and western India. In other areas, detailed MT/AMT studies need to be expedited. This review paper presents the art of geothermal exploration in India by using MT/AMT techniques and identifies potential zones that can be exploited for power generation and direct application. Reservoir characteristics, carbon emissions reduction methods, and levelised cost factor are also discussed.

Deciphering The Magma Storage Conditions And Preeruptive Processes At Cumaçay: A Plio-Quaternary Volcanic Eruption Center In Eastern Anatolia, Turkey, Yavuz Özdemi̇r, Ayhan Özdemi̇r

Turkish Journal of Earth Sciences

We investigate the geology and petrology of Cumaçay, one of the Plio-Quaternary eruption centers of postcollisional volcanism in Eastern Turkey, using a combination of geochronology, bulk-rock geochemistry, thermobarometry, and thermodynamic simulations. Our new K-Ar ages reveal an age of 3.5-0.97 Ma for the eruptive products, which spread around an area of approximately 1000 km². Mineral-melt equilibria for olivine, orthopyroxene, clinopyroxene, and plagioclase allow estimation of crystallization pressures, and temperatures indicate two separate crustal storage of crystallization at 14-28 km and 5-15 km. The temperature estimation from diverse methods ranges from 954 °C to 1224 °C. Thermodynamic modelings using …

Characterization And Dissolution Behaviors Of The Çatalağzı (Zonguldak, Turkey) Power Plant Fly Ash, Hati̇ce Yilmaz

Turkish Journal of Earth Sciences

This study focused on the characterization and dissolution behaviors of fly ash produced by the Çatalağzı power plant (Zonguldak, Turkey) in which bituminous coal is burned. The fly ash, containing mainly a glassy phase and small crystalline phases, is a typical class F fly ash with pozzolanic properties. Therefore, it can be used in many different areas. For this material to be used safely, it is necessary to determine its dissolution behavior as well as its physical, chemical, mineralogical, and morphological properties. The dissolution behavior of the Çatalağzı power plant fly ash (CFA) was examined by two standard methods, namely …

New High Resolution Aeromagnetic Anomaly Map Of Türkiye And Its Various Derivative-Based Maps, Alper Kiyak, Eren Pamuk, Serkan Köksal, Mustafa Levent Bakar, Serdar Tosuner

Turkish Journal of Earth Sciences

Since Türkiye's territory is mostly mountainous and forested, earth science studies in these areas have not been completed at an adequate level and with a satisfying resolution. However, due to the long time and cost of collecting measurements from land in large- and medium-scale studies and due to the inability to collect measurements in regular grid intervals in large-scale studies to be carried out on land, an airborne geophysical survey project was conducted in order to collect high-resolution magnetic and radiometric country-scale data. Total magnetic field and radiometry data were collected from the air between 2017 and 2022 within the …

A Local Earthquake Tomography On The Eaf Shows Dipping Fault Structure, Sezi̇m Ezgi̇ Güverci̇n

Turkish Journal of Earth Sciences

The East Anatolian Fault Zone (EAFZ) is a left-lateral transform fault zone located between the Anatolian and Arabian plates. In this study, in order to image the upper crustal structure beneath the eastern segments of EAFZ, 3D seismic velocity variations are computed using local earthquake tomography. The initial catalog for the tomography process consists of 2200 well-located earthquakes recorded at 49 seismic stations around the study region between 2007 and 2020. 1D initial velocity model is constructed based on previous studies in the region. The maximum number of iterations and the velocity perturbations which sustain the linearity of the inversion …

Variations In Coupling And Deformation Along The Hellenic Subduction Zone, Michael Floyd, Robert King, Demitris Paradissis, Hayrullah Karabulut, Semi̇h Ergi̇ntav, Kostas Raptakis, Robert Reilinger

Turkish Journal of Earth Sciences

GNSS observations in and around the Aegean Sea, Peloponnese, and western Turkey are sufficiently precise and densely spaced to provide an image of the deformation associated with the Hellenic subduction zone. To isolate deformation associated with the plate boundary, we use GNSS secular velocities and shallow earthquake locations to determine an upper plate reference frame with low internal deformation (/yr) that includes a large area of the central and western Aegean. We interpret upper plate deformation as resulting from stronger coupling on the subduction plate interface beneath western Crete than on the western or eastern segments of the Hellenic subduction …

Internal Deformation Of Continental Blocks Within Converging Plates: Insights From The Ovacık Fault (Anatolia, Türkiye), Cengi̇z Zabci, Taylan Sançar, Dmitry Tikhomirov, Susan Ivy-Ochs, Christof Vockenhuber, Anke M. Friedrich, Müge Yazici, Naki̇ Akçar

Turkish Journal of Earth Sciences

The active tectonics of Anatolia is mostly characterized by its westward motion with respect to Eurasia between the Hellenic subduction in the west and Arabia-Eurasia continental collision in the east. Although most of the deformation is suggested to be confined along Anatolia?s boundary elements, viz. the North and East Anatolian shear zones, recent studies indicate a higher magnitude of internal strain accumulation, especially along the parallel/subparallel strike-slip faults of its central province. We present the first morphochronology-based slip rate estimate for one of these strike-slip structures, the Ovacık Fault, by using cosmogenic 36Cl dating of offset fluvial deposits. At the …
