Watershed Sciences Faculty Publications
Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico. More than two dozen authors—most with decades of experience—review the origins of riparian science in the western United States, document what is currently known about riparian ecosystems, and project future needs. Topics are widespread and include: interactions with fire, climate change, and declining …
Adapting Low-Cost Drone Technology To Cubesats For Environmental Monitoring And Management: Harmful Algal Bloom Satellite-1 (Habsat-1), Richard Beck, Hongxing Liu, Richard Johansen, Min Xu, Catharine Mcghan, George Thomas Black, Ou Ma, Uc Cubecats, Molly K. Reif, Erich B. Emery, Richard Stumpf, Greg Emerick, Ryan Nelson

Reif, Erich B. Emery, Richard Stumpf, Greg Emerick, Ryan Nelson
Small Satellite Conference
HABsat-1 is designed to improve our understanding of algal bloom dynamics and their causes on land by addressing several current limiting factors for this application using existing satellites. For example, there is suboptimal imager design for water, insufficient spatial resolution for precise co-registration of surface observations, and too few satellites with such capabilities to defeat cloud cover in maritime, tropical and temperate climates. We will overcome these problems by merging a new low-cost multispectral imaging technology with a low-cost CubeSat bus. CubeSats cost roughly 1/100th to 1/1000th of most current long-life imaging satellites. Such cost decreases are necessary to improve …
Why Do They Do That? Understanding Factors Influencing Visitor Spatial Behavior In Parks And Protected Areas, Abigail M. Sisneros-Kidd
Why Do They Do That? Understanding Factors Influencing Visitor Spatial Behavior In Parks And Protected Areas, Abigail M. Sisneros-Kidd
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Visitors to parks and protected areas within the United States and worldwide often visit these areas with a particular destination in mind, such as seeing Old Faithful erupt in Yellowstone National Park or standing on the rim of the Grand Canyon in Grand Canyon National Park. These visitor use destinations, and the pathways leading to them, such as trails and roadways, see high levels of use, and as a result, impacts to soil, vegetation, air, water, soundscapes, and night skies that result from this use. The field of recreation ecology studies these impacts to park and protected area resources resulting …
On The Relationship Between Phylogenetic Diversity And Trait Diversity, Caroline M. Tucker, T. Jonathan Davies, Marc W. Cadotte, William D. Pearse

Niche differences are key to understanding the distribution and structure of biodiversity. To examine niche differences, we must first characterize how species occupy niche space, and two approaches are commonly used in the ecological literature. The first uses species traits to estimate multivariate trait space (so‐called functional trait diversity, FD); the second quantifies the amount of time or evolutionary history captured by a group of species (phylogenetic diversity, PD). It is often—but controversially—assumed that these putative measures of niche space are at a minimum correlated and perhaps redundant, since more evolutionary time allows for greater accumulation of trait changes. This …
Maternal Vitamin D Deficiency And Early Childhood Health Outcomes Including Autism Development, Kelsey L. Girardelli
Maternal Vitamin D Deficiency And Early Childhood Health Outcomes Including Autism Development, Kelsey L. Girardelli
Undergraduate Honors Capstone Projects
Many studies have shown that vitamin D deficiency during pregnancy is associated with a variety of adverse maternal and pediatric outcomes. Disease outcomes that have been observed in pregnant women who are vitamin D deficient include increased risk of C-section, preeclampsia, bacterial vaginosis, and gestational diabetes. In children born to deficient mothers, increased rates of childhood asthma, type 1 diabetes, low birthweight, and autism spectrum disorder (ASD) have been observed. Although there is much evidence to support these correlations, much is yet to be understood regarding the etiology of these outcomes. This paper specifically examines the relationships between risk factors …

Our understanding of how human activities impact insect communities is limited. Dung beetles, well known for the ecosystem services they provide, are faced with many conservation threats, particularly from deforestation and agriculture. Here we used 200-m transects and human-dung—baited pitfall traps to examine dung beetle populations in 7 forests of Maryland's Coastal Plain. We set traps once a month, from May 2014 to April 2015, to determine species presence, abundance, range, and seasonality. We collected 6463 individuals representing 22 species; Janes Island State Park (JISP) had the highest abundance (2705 individuals) and Martinak State Park (MSP) had the highest species …
