Lessons From A Landscape Irrigation Rebate Program In Miami Dade County, Haimanote K. Bayabil, Laura Vasquez, Jesus Lomeli, Patrick Martin 2021 University of Florida

Lessons From A Landscape Irrigation Rebate Program In Miami Dade County, Haimanote K. Bayabil, Laura Vasquez, Jesus Lomeli, Patrick Martin

Journal of Extension

We calculated savings in outdoor water uses from 37 properties in Fisher Island, Florida, that were retrofitted with smart Evapotranspiration-based irrigation controllers through the Miami Dade County’s Landscape Irrigation Rebate Program. We found average water savings of 11.4 million gallons per year from the 37 properties on the island. We discuss the roles of extension personnel in developing and effectively managing an irrigation rebate program and the implications of results from this program for large scale efforts towards efficient use of freshwater resources.


Evaluating Toxicity Of Varroa Mite (Varroa Destructor)-Active Dsrna To Monarch Butterfly (Danaus Plexippus) Larvae, Niranjana Krishnan, Maura J. Hall, Richard L. Hellmich, Joel R. Coats, Steven P. Bradbury 2021 Iowa State University

Evaluating Toxicity Of Varroa Mite (Varroa Destructor)-Active Dsrna To Monarch Butterfly (Danaus Plexippus) Larvae, Niranjana Krishnan, Maura J. Hall, Richard L. Hellmich, Joel R. Coats, Steven P. Bradbury

Entomology Publications

Varroa mites (Varroa destructor) are parasitic mites that, combined with other factors, are contributing to high levels of honey bee (Apis mellifera) colony losses. A Varroa-active dsRNA was recently developed to control Varroa mites within honey bee brood cells. This dsRNA has 372 base pairs that are homologous to a sequence region within the Varroa mite calmodulin gene (cam). The Varroa-active dsRNA also shares a 21-base pair match with monarch butterfly (Danaus plexippus) calmodulin mRNA, raising the possibility of non-target effects if there is environmental exposure. We chronically exposed the entire monarch larval stage to common (Asclepias syriaca) and tropical ...


Financial Analysis Of Converting Rural Lawns To Pollinator Habitat In The Corn Belt, Adam K. Janke, John C. Tyndall, Steven P. Bradbury 2021 Iowa State University

Financial Analysis Of Converting Rural Lawns To Pollinator Habitat In The Corn Belt, Adam K. Janke, John C. Tyndall, Steven P. Bradbury

Natural Resource Ecology and Management Publications

Conservation efforts in rural landscapes seek to improve the multifunctional nature of land uses for people and the biotic communities that support them. In these environments, existing turfgrass lawns mowed routinely through the summer present an opportunity where changes in management from intensively managed monocultures to diverse native perennial vegetation can stack environmental benefits by improving soil health, water quality, and wildlife habitat. Conversion of lawns to pollinator habitat can help achieve continental goals of reversing declines in high-profile species such as the monarch butterfly Danaus plexippus and native bees. Here, we examine the financial implications for landowners and managers ...

Wetland ecosystems play fundamental roles in regulating our freshwater resources, yet they are not comprehensively protected from degradation and loss. West Virginia, USA has wetlands across diverse landscapes and geography that feed into both the Chesapeake Bay and Gulf of Mexico. The state is also comprised of diverse anthropogenic land-use practices. We are assessing 200 wetlands over 2 years to evaluate how anthropogenic disturbance impact wetland water quality functions. Select water quality parameters (20), and relative diversity and abundance of vegetation and macroinvertebrates will be used as bioindicators. They will be compared with GIS assessments of watershed land cover/ land-use ...


Do Mitigated Wetlands Support Similar Small Mammal Communities As Natural Wetlands?, Krista Noe, Mack Frantz, Christopher T. Rota, Jim Anderson 2021 West Virginia University

Do Mitigated Wetlands Support Similar Small Mammal Communities As Natural Wetlands?, Krista Noe, Mack Frantz, Christopher T. Rota, Jim Anderson

Presentations

Wetlands provide many ecosystem services and play an important ecological role in wildlife communities. Although wetland mitigation is a standard tool to combat losses to natural wetlands, it is essential to understand if mitigated wetlands are truly replacing natural wetlands in their full capacity. Because one important role of wetlands is to provide habitat for wildlife communities, it is important to determine if these created or restored wetlands can foster a wildlife community that is similar to natural wetlands. One understudied taxa in the realm of wetland mitigation research is small mammals. Our objectives are to examine community composition, occupancy ...

Farm To Boardroom: How Improving Farm Conditions Leads To Sustained And Ethical Profit, Emily Mueller

Student Theses 2015-Present

As a society evolving and innovating at a pace faster than ever before seen in human history, we find ourselves at a crossroads of dealing with planetary boundaries and improving social standards. We are met with a crisis just thirty years away; the crisis of needing to be able to effectively and sustainably feed ten billion people across the globe. The 20th century brought on a booming age for industrializing the food system in order to increase yield and thus profit. The new process was a significant breakthrough at its time, but now we must face the question of when ...


Integrated Estuary Governance, Mary Jane Angelo, J.W. Glass 2021 William & Mary Law School

Integrated Estuary Governance, Mary Jane Angelo, J.W. Glass

William & Mary Environmental Law and Policy Review

Estuaries are complex, dynamic ecosystems that play a critical role in supporting crucial economic industries, such as commercial fishing and tourism, and providing the resources necessary to sustain coastal communities. A range of anthropogenic environmental stressors are threatening the health of estuaries throughout the world. Traditional top-down single resource focused environmental regulatory approaches have proved inadequate to protect and restore estuarine systems. In recent years, scientific and legal academics, as well as policymakers, have called for more holistic participatory approaches to addressing environmental challenges. Drawing on the literature on ecosystem management, integrated water resources management, collaborative governance, and adaptive management ...


Conceptual Framework Linking Resource Size And Recreational Use, Derek Kane 2021 University of Nebraska-Lincoln

Conceptual Framework Linking Resource Size And Recreational Use, Derek Kane

Dissertations & Theses in Natural Resources

Participation in recreational activities at natural resource systems is important to many people. However, the use of these resource systems can cause negative social and ecological impacts. To manage the potential negative impacts of resource use, natural resource managers must have the ability to quantify and monitor the amount of use that is occurring. Unfortunately, it is difficult and costly to quantify and monitor resource system use. Natural resource management would benefit from uncovering a simple, easily accessible metric that could predict resource system use. The size of a resource system is related to social and ecological aspects of the ...


Tree Species Of Wet Tropical Forests Differ In Their Tissue Biochemistry And Effects On Soil Carbon Dynamics, Ann E. Russell, Rachel F. Marek, Daniel C. Olk 2021 Iowa State University

Tree Species Of Wet Tropical Forests Differ In Their Tissue Biochemistry And Effects On Soil Carbon Dynamics, Ann E. Russell, Rachel F. Marek, Daniel C. Olk

Natural Resource Ecology and Management Publications

Given the hypothesized effects on soil organic matter (SOM) of polyphenols in plant tissues, differences among tree species in their biochemical composition could influence the turnover and accrual of SOM in various ways. The extent to which the biochemical composition of leaf and fine-root tissues differ among tropical tree species, and the effects on soil dynamics, are largely undocumented, however. We used cupric oxide analyses of plant tissues and soil in long-term, replicated, mono-dominant 15-year-old plantations at La Selva Biological Station, Costa Rica, to test for differences among six tree species. We related these results to companion studies in this ...

Evaluating Urban Parks Accessibility And Equity: A Case Study Of Hartford, Ct And New Haven, Ct, Natalie Roach, Mara Tu

Honors Scholar Theses

Public parks provide cities with environmental benefits, positive health effects, recreational opportunities, community building, educational spaces, and public amenities. However, certain populations have been systematically denied their fair share of these benefits because of unjust practices in the creation and maintenance of urban parks. With a lens of environmental justice, the goal of this research was to assess park quality and accessibility of two Connecticut cities, Hartford and New Haven, by gathering publicly available information as well as using GIS tools.

The Trust for Public Land (TPL) has an existing ParkScore rating system that evaluates the quality of a city ...


Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank 2021 University of Southern Maine

Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank

Thinking Matters Symposium

In the United States, the legal framework for product date labeling is minimal and varies across states. Manufacturers have the discretion to use any date label that they deem appropriate, and this lack of uniformity leaves room for misinterpretation by both retailers and consumers. Previous studies have examined consumer misinterpretation of date labels and how this lack of knowledge correlates to food waste behaviors. This study was aimed at understanding how consumers apply their knowledge about date labels to make decisions about purchasing and discarding food. The research was conducted via an intercept survey outside of a grocery store to ...


The Power Of Information: Information, Leak Notices, And Water Conservation In Edina, Mn, Federico Chung 2021 Macalester College

The Power Of Information: Information, Leak Notices, And Water Conservation In Edina, Mn, Federico Chung

Economics Honors Projects

This paper provides evidence on the effects of information provision on households’ water use. I use quarterly household consumption data from a utility in Minnesota to test the effect of a new residential water billing system on households’ water consumption. The updated billing format was possible as the utility transitioned to an automated meter reading (AMR) system. I also study impacts of another source of improved information provision from AMR adoption, faster high-water consumption notices. I find mixed evidence of the impact of personalized information on households’ water use. Households respond to high-consumption notices by significantly reducing consumption, even relative ...


Bioaccumulation And Partitioning Of Heavy Metals In Cicindelidia Haemorrhagica In Yellowstone National Park, Monica Gotschall 2021 University of Nebraska-Lincoln

Bioaccumulation And Partitioning Of Heavy Metals In Cicindelidia Haemorrhagica In Yellowstone National Park, Monica Gotschall

Dissertations & Theses in Natural Resources

The tiger beetle Cicindelidia haemorrhagica (Coleoptera: Cicindelidae) are widely distributed in Yellowstone National Park (YNP) and exclusively living on thermal areas. Heavy metals including arsenic, copper, lead, and selenium are present in these thermal springs, presenting an unique environment for C. haemorrhagica. Therefore, from 2018 – 2020 I sampled adult C. haemorrhagica from YNP and adult C. haemorrhagica from a known population in a salt flat in Idaho not associated with a hot spring and measured heavy metal concentrations. All populations of C. haemorrhagica bioaccumulated heavy metals. Cuticular waxes showed small concentrations of metals indicating that those metals are being excreted ...


Groundwater-Ephemeral Stream Interaction Before And After Storm Events, Jennifer Sabbak 2021 Susquehanna University

Groundwater-Ephemeral Stream Interaction Before And After Storm Events, Jennifer Sabbak

Senior Scholars Day

Almost 60 percent of stream miles in the continental United States only flow seasonally or after storms according to a study done by the EPA in 2013. Although these streams make up a vast majority of stream miles throughout the United States, seasonal and ephemeral stream channels are not often regularly monitored. This study will focus on analyzing the hydrology of an unnamed, underrepresented ephemeral stream within Snyder County, Pennsylvania. This stream runs through Susquehanna University’s CEER site and drains into Penn Creek. The objective of this study is to accurately represent the stream’s groundwater recharge rate by ...

Tournament And Non-Tournament Anglers Have Little Effect On A Largemouth Bass Population Compared To Natural Mortality, Andrea Sylvia, Stephen J. Dinsmore, Michael J. Weber

Natural Resource Ecology and Management Publications

Popularity of bass Micropterus spp. catch and release and tournament angling during the past decade has resulted in increased potential for these activities to induce population level effects. Understanding capture rates and mortality sources relative to total population mortality is essential to focus of management. We conducted monthly electrofishing, solicited nontournament angler tag returns, and censused largemouth bass Micropterus salmoides tournaments at Brushy Creek Lake, IA, USA from April 2015 to June 2018. We used a multistate mark-recapture model to evaluate the effects of air temperature, water temperature, tournament bass per angler, and tournament initial mortality on non-tournament and tournament ...

Reptiles utilize a variety of environmental cues to inform and drive animal behavior such as chemical scent trails produced by food or conspecifics. Decrypting the scent-trailing behavior of vertebrates, particularly invasive species, enables the discovery of cues that induce exploratory behavior and can aid in the development of valuable basic and applied biological tools. However, pinpointing behaviors dominantly driven by chemical cues versus other competing environmental cues can be challenging. Y-mazes are common tools used in animal behavior research that allow quantification of vertebrate chemosensory behavior across a range of taxa. By reducing external stimuli, Y-mazes remove confounding factors and ...

Reimagining The Duck Stamp, Hunting Licensure And Public Land Preservation, Alec Wayne Boyd-Devine 2021 Western Kentucky University

Reimagining The Duck Stamp, Hunting Licensure And Public Land Preservation, Alec Wayne Boyd-Devine

Masters Theses & Specialist Projects

The American Migratory Bird Hunting and Conservation Stamp, or Duck Stamp, is a form of licensure issued by the Federal Government for waterfowl hunters. Why do physical stamps act as licensure to hunt waterfowl on both public and private land in the United States? How did the stamp become the key that grants access to resources that supposedly should be owned by the public? The duck stamp has been well-documented in conservation communities as a resource which has made significant positive impacts on the environment. The increase of anti-hunting sentiments in our society combined with fewer hunters per capita may ...
