Effects Of Culling White-Tailed Deer On Tree Regeneration And Microstegium Vimineum, An Invasive Grass, John Paul Schmit, Elizabeth R. Matthews, Andrejs Brolis

United States National Park Service: Publications

Reduction of forest regeneration due to overbrowsing by white-tailed deer is a growing concern for land managers. Abundant deer can impede forest regeneration through direct predation on tree seedlings. Additionally high deer density can facilitate the establishment of a dense understory of browse tolerant plant species that shades seedlings and persists even in the absence of deer. In response to these challenges, land managers have sought to reduce deer herds to restore tree regeneration, but few studies have evaluated the effectiveness of this management. Our study took place in Catoctin Mountain Park, a US National Park Service unit with a …

Toward A Multifaceted Heuristic Of Digital Reading To Inform Assessment, Research, Practice, And Policy, Julie Coiro

College of Education Faculty Publications

In this commentary, the author explores the tension between almost 30 years of work that has embraced increasingly complex conceptions of digital reading and recent studies that risk oversimplifying digital reading as a singular entity analogous with reading text on a screen. The author begins by tracing a line of theoretical and empirical work that both informs and complicates our understanding of digital literacy and, more specifically, digital reading. Then, a heuristic is proposed to systematically organize, label, and define a multifaceted set of increasingly complex terms, concepts, and practices that characterize the spectrum of digital reading experiences. Research that …

The Business Of Peace: Understanding Corporate Contributions To Conflict Management, Molly M. Melin

Political Science: Faculty Publications and Other Works

Do private firms act beyond “business as usual” and proactively build peace? Firms are largely absent from the conflict management literature, despite studies suggesting their importance. What conditions encourage firms to actively prevent or resolve violent conflict? Are such actions interdependent with ongoing international conflict prevention and management efforts? I argue international efforts encourage corporate conflict management-related activities since conflict management interdependencies can decrease the costs of conflict management, while increasing the benefits and success of their efforts. In addition, firms respond to gaps in governance and instability, especially when they are norm entrepreneurs or their reputation is threatened. I …

Nurse Rock Microclimates Significantly Buffer Exposure To Freezing T Temperature And Moderate Summer Temperature, Joshua L. Conver, Elliott Yarwood, Lucas D. Hetherington, Don E. Swann

United States National Park Service: Publications

Nurse tree canopies mitigate exposure to freezing temperatures that could result in injury or mortality to the saguaro cactus (Carnegiea gigantea). Abiotic objects have been hypothesized to provide similar beneficial microclimates. We used data loggers at 11 nurse rock sites to record daily daytime summer maximum and winter nighttime minimum temperatures at Saguaro National Park, Arizona, to examine the effectiveness of rocks to moderate seasonal temperature extremes in the microclimate. Temperatures at rock sites averaged 2 °C warmer than exposed open control sites in winter. We found that the efficiency of rocks to act as insulators significantly increased as temperature …

Global Karst Springs Hydrograph Dataset For Research And Management Of The World’S Fastest-Flowing Groundwater, Tunde Olarinoye, Tom Gleeson, Vera Marx

KIP Articles

Karst aquifers provide drinking water for 10% of the world’s population, support agriculture, groundwater-dependent activities, and ecosystems. These aquifers are characterised by complex groundwater-flow systems, hence, they are extremely vulnerable and protecting them requires an in-depth understanding of the systems. Poor data accessibility has limited advances in karst research and realistic representation of karst processes in large-scale hydrological studies. In this study, we present World Karst Spring hydrograph (WoKaS) database, a community-wide effort to improve data accessibility. WoKaS is the first global karst springs discharge database with over 400 spring observations collected from articles, hydrological databases and researchers. The dataset’s …

How To Develop Grass-Based Livestock Husbandry In Areas Of Low- And Middle-Yield Fields, Gao Shuqin, Wang Hongsheng, Duan Rui, Jing Hai-Chun, Fang Jingyun

Bulletin of Chinese Academy of Sciences (Chinese Version)

With increasing awareness of balanced and healthy diet, the demand for ruminant products has been drastically increasing in China over the past decades. Grass-based Livestock Husbandry (GLiH), a new paradigm for agricultural restructuring and sustainable development, is highly encouraged to meet such demand. Yet, the country's own production cannot self-support the demand, as envisaged by the soaring import of both red meats and forage products, albeit half of the nation's cereal production is devoted to animal feed and forage crop production area amounts to 12 million ha. With the affluent population and limited arable land, China is facing challenge to …

Research On Soil Carbon Storage Of Alpine Grassland Under Different Uses In Qinghai-Tibet Plateau, Tao Li, Youmin Gan, Lei Ji, Shujing Yang, Zhongqi Song

IGC Proceedings (1977-2023)

In recent years, with the temperature rising on the Qinghai-Tibet Plateau, studies have shown that (Shaoqing Wang et al. 1999; Yuchun Qi et al. 2003) the plateau permafrost has great potential for emissions of greenhouse gases such as carbon, nitrogen, because of the remarkable permafrost thermal sensitivity. The Qinghai-Tibet Plateau is a special geographical and ecological unit, which has an important role in global climate change. The study of soil carbon storage of grassland ecosystems in the Qinghai-Tibet Plateau and its distribution characteristics allow the evaluation of different land management. The carbon cycle response and feedback effects of …

Invasive Vegetation Affects Amphibian Skin Microbiota And Body Condition, Obed Hernandez-Gomez, Allison Q. Byrne, Alex R. Gunderson, Thomas S. Jenkinson, Clay F. Noss, Andrew P. Rothstein, Molly C. Womack, Erica B. Rosenblum

Natural Sciences and Mathematics | Faculty Scholarship

Invasive plants are major drivers of habitat modification and the scale of their impact is increasing globally as anthropogenic activities facilitate their spread. In California, an invasive plant genus of great concern is Eucalyptus. Eucalyptus leaves can alter soil chemistry and negatively affect underground macro- and microbial communities. Amphibians serve as excellent models to evaluate the effect of Eucalyptus invasion on ground-dwelling species as they predate on soil arthropods and incorporate soil microbes into their microbiotas. The skin microbiota is particularly important to amphibian health, suggesting that invasive plant species could ultimately affect amphibian populations. To investigate the potential for …

A Case Study: Perceptions Of An Indigenous Stem Nonprofit Contributions To Self-Efficacy And Educational Experience, Tyler Parisien

CUP Ed.D. Dissertations

Native American people and Indigenous people are underrepresented in the Science, Technology, Engineering, and Mathematics (STEM) disciplines. According to the National Science Foundation (NSF, 2015), Indigenous people represented 1.7% of the United States population, but only accounted for 0.6% of bachelor’s degrees, 0.4% of master’s degrees, and 0.2% of doctoral degrees in science and engineering. The low participation of Indigenous people in STEM disciplines have been attributed to reasons such as (a) lack of exposure, (b) lack of interest, (c) lack of confidence, (d) lack of a sense of belonging, and (e) lack of goal congruency. This qualitative research study …

The Internal, External And Extended Microbiomes Of Hominins, Robert R. Dunn, Katherine R. Amato, Elizabeth A. Archie, Mimi Arandjelovic, Alyssa N. Crittenden, Lauren M. Nichols

Anthropology Faculty Research

The social structure of primates has recently been shown to influence the composition of their microbiomes. What is less clear is how primate microbiomes might in turn influence their social behavior, either in general or with particular reference to hominins. Here we use a comparative approach to understand how microbiomes of hominins have, or might have, changed since the last common ancestor (LCA) of chimpanzees and humans, roughly six million years ago. We focus on microbiomes associated with social evolution, namely those hosted or influenced by stomachs, intestines, armpits, and food fermentation. In doing so, we highlight the potential influence …

Oceanographic Structure And Light Levels Drive Patterns Of Sound Scattering Layers In A Low-Latitude Oceanic System, Kevin M. Boswell, Marta D'Elia, Matthew Johnston, John A. Mohan, Joseph D. Warren, R. J. David Wells, Tracey Sutton

Biology Faculty Articles

Several factors have been reported to structure the spatial and temporal patterns of sound scattering layers, including temperature, oxygen, salinity, light, and physical oceanographic conditions. In this study, we examined the spatiotemporal variability of acoustically detected sound scattering layers in the northern Gulf of Mexico to investigate the drivers of this variability, including mesoscale oceanographic features [e.g., Loop Current-origin water (LCOW), frontal boundaries, and Gulf Common Water]. Results indicate correlations in the vertical position and acoustic backscatter intensity of sound scattering layers with oceanographic conditions and light intensity. LCOW regions displayed consistent decreases, by a factor of two and four, …

Isotope-Based Methods For Evaluating Fish Trophic Geographies, Julie L. Vecchio

USF Tampa Graduate Theses and Dissertations

Data on the movement and diets of fish during a variety of life stages are important inputs to fisheries stock assessments and marine ecosystem models. Stable isotopes may provide previously inaccessible information on movement and diet of a variety of managed and forage fish species. Here I used several novel means of interpretation for stable isotope data to infer diets and movements of several important fisheries species over both short (weeks to months) and long (lifetime) timescales. To calculate a constant partitioning offset (CPO) between the δ¹⁵N of muscle and of liver tissue, I conducted a literature search …

Publications and Research

Research Summary:

The current study analyzes the crime reduction effect of a police sub-station operating within a business improvement district in Newark, NJ. Synthetic control methods were used to create a control group that was statistically equivalent to the cumulative street units in the target area. Significant reductions of burglary and motor vehicle theft were observed in the target area as compared to a synthetic control area over the post-intervention period. Robbery and theft from auto, conversely, suffered from spatial displacement. Of the six police actions included in the process evaluation, quality-of-life summonses and directed patrols increased in the post-intervention …

Beryllium-7 Elucidate Sediment Dynamics Of The Branford River Estuary, Connecticut, Usa, Gaboury Benoit, Matthew Hirschbeck, Beth Bisson

United States National Park Service: Publications

Berrylium-7 elucidates sediment dynamics (i.e., sources, sinks, deposition, and resuspension) in a Connecticut estuary. Average 7 −2−1 annual atmospheric deposition of Be is 290 mBq cm year. Sediment samples from 43 locations within the estuary show that 7Be deposition is spatially complex, but were statistically indistinguishable a year apart. Weekly time series of sediments indicate 7 that levels are nearly constant on this shorter time scale on ceradio active decay is taken into account. Be levels in sediments area balance between steady losses through radioactive decay and periodic pulse inputs following rainstorms. The water column was measured intensively during three …

Implications Of Organic Mass To Carbon Ratios Increasing Over Time In The Rural United States, W.C. Malm, B.A. Schichtel, J.L. Hand, A.J. Prenni

United States National Park Service: Publications

The thermal evolution procedure used by most monitoring programs in the United States to determine carbonaceous aerosol concentrations is referred to as the thermal‐optical reflectance method, where an aerosol sample that has been collected on a quartz filter is heated and evolved carbon is characterized as either organic (OC) or light absorbing carbon (LAC). Evolved carbon assigned to OC is multiplied by a factor, Roc, to achieve an estimate of organic mass. Over the last 10–15 years, Roc, estimated through multiple linear regression analysis of data collected in the Interagency Monitoring of Protected Visual Environments (IMPROVE) program, has increased at …

Netnography: Origins, Foundations, Evolution And Axiological And Methodological Developments And Trends, Greiciele M. Morais, Valdeci F. Santos, Carlos A. Gonçalves

The Qualitative Report

Netnography originated in ethnography and evolved following the advances in data transmission technology. The netnographic method is distinguished by its axiological orientation residing in recognition of online social experiences. The main method for data collection adopted by the netnographer is participant observation. One premise that must be observed is the necessary estrangement, which means that the researcher must be a layman as regards the object of study. In the field of administration, netnography emphasized the area of marketing and consumer behavior. The goal is to understand the consumer culture of online communities. One of its main challenges consists of how …
