Rapid Assesment Of Aquatic Insect Diversity And Abundance Used To Evaluate The Quality Of Stream Restoration, Kaleb Stephen Kindoll

2023 Midwest Ecology & Evolution Conference

Stream and wetland restoration activities seek to improve the function of aquatic ecosystems. Measurement of the diversity and abundance of aquatic insects are commonly used to evaluate the success of restoration efforts, but these measurements are often very time consuming. In this study, we attempt to construct an efficient method that can be used to rapidly assess the diversity and abundance of aquatic insects as a measure of the quality of stream restoration. We suspended uniform sized pieces of cardboard paper coated with adhesive to trap insects in three different environments: one restored and two unrestored streams with similar characteristics. …

Monitoring Personal Exposure To Air Quality Gradients While Biking On An Elevated Urban Trail, Gavin Salas

2023 Midwest Ecology & Evolution Conference

Air pollution is a major global health concern, specifically as it relates to the human exposome. The EPA criteria pollutants, including particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), and NOx can have severe impacts on respiratory and cardiovascular health, particularly in populations with chronic illnesses such as asthma, those facing economic hardships and individuals who frequently spend time outdoors, such as bicyclists and runners. To understand the impact of air pollution on human health, it is essential to assess personal exposure. This study aimed to investigate personal exposure to air pollution levels while biking along a former elevated …

Hydrological Patterns Of The Chimborazo Reserve: Streamflow, Climate, And Glacier Recession Data Show A Loss Of Glacial Influence On The Southwestern Aspect Of The Chimborazo Volcano, Ecuador., William F. M. Patrick

Independent Study Project (ISP) Collection

The Chimborazo volcano of the central Ecuadorian Andean Cordillera (6310 m) has been shown to currently be undergoing extreme glacial recession due to climate change. For this reason, this study sought to analyze climate and glacier recession data in conjunction with streamflow from kryal (glacial-fed), rhithral (non-glacial-fed), and intermediate streams to not only evaluate the current health of Chimborazo’s glaciers, but also determine how hydrology in the region will respond to future climate change. The rate of glacial recession on the volcano was determined using satellite imagery between 1965 and 2019. Measurements of stream elevation, pH, water temperature, width, depth, …

Impact Of Wildlife Provisioning On Species Diversity, Relative Frequency, And Richness In New South Wales, Alanah Cohen-Tigör

Independent Study Project (ISP) Collection

Wildlife provisioning and camera trapping are two recently evolving methods of conservation and wildlife management, aimed at protecting animals in the face of ever worsening climate change. Habitats are being destroyed by climate disruption, decreasing species diversity and abundance worldwide. It is imperative that methods of protecting species are developed to slow or reverse this era of extinction. By providing supplementary food and water to ecological communities, the hope is that species will have improved survivorship and reproduction, making them more resilient and resistant to population decline. Camera trapping is product of modern technology, allowing researchers to monitor species without …

Coastal Morphology And Sediment Deposition On Adjacent Coral Reefs At Misali Island, Sophia Rosati

Independent Study Project (ISP) Collection

Terrestrial and marine ecosystems are frequently interpreted under separate lenses. On a 1 km wide island, however, these two sciences are inextricably tied. Misali Island, a small coralline island in the Indian Ocean, has been largely uninhabited for its entire history, making this coastal interface unique. In this study, Misali Island is used as a study region to demonstrate how natural processes are materializing in the Zanzibar Archipelago. Methods employed, both geological and marine, work to understand the erosional circumstances of Baobab Beach and the inherent effects on local coral reefs. Results show that Misali’s northeastern beachfront is currently under …

Individual-Level Responses To Rapid Climate Change In Common Terns (Sterna Hirundo) And Arctic Terns (Sterna Paradisaea), Kaiulani A. Sund

Student Publications

This study examines fine-scale environmental changes and intraspecific variation in the diet and foraging behavior of two seabirds in the Gulf of Maine, one of the fastest-warming regions of the ocean. This variation on the individual level, or behavioral plasticity, may help long-lived species to persist in rapidly changing environments. As the water warms, seabirds’ preferred prey (hake and herring) follow cooler waters deeper and farther offshore. It is unlikely that all individuals respond to changing food availability in the same way. For common terns (Sterna hirundo) and Arctic terns (Sterna paradisaea) breeding on Petit Manan …

One Man’S Trash: Duke Riley’S Archive And The Social Construction Of Garbage, Deirdre M. Sullivan

Student Publications

In a post-industrial society, Americans have to grapple with the result of seemingly endless production: trash. The amount of trash produced every day is a rising threat to the planet and its inhabitants; every decision made for the future must also take into account waste, rubbish, and refuse that will never break down or be fully removed from our waterways. Some artists, such as contemporary artist Duke Riley, have embraced the use of trash in their art as a critique of capitalism and consumerism. One of his most notable works is the Poly S. Tyrene Memorial Maritime Museum series, a …

Drinking Water Contaminants: Bacteria, Bruce I. Dvorak, Becky O. Schuerman

Department of Civil and Environmental Engineering: Faculty Publications

Testing drinking water for fecal bacteria or Escherichia coli (E. coli) is commonly used as an indicator of the presence of pathogenic microorganisms. The presence of pathogenic (disease-causing) microorganisms is a concern when considering the safety of drinking water. Pathogenic microorganisms can cause flu-like systems, intestinal infections, dysentery, hepatitis, typhoid fever, cholera, and other illnesses.

Spatial Ecology And Habitat Preference Of Yellow-Spotted Monitors (Varanus Panoptes) At Lizard Island National Park, Qld, Australia, Ryan Snyder

Independent Study Project (ISP) Collection

Lizard Island National Park is an area of strong habitat diversity, especially given its small size. There are several distinct habitats represented, including open sclerophyll woodlands, mangrove swamps, dune grasslands, foothills elevations, and of course anthropogenically modified human habitats. The object of this study was to observe the abundances and behaviors of the yellow-spotted monitor lizard (V. panoptes) in each of these habitat settings to answer the question of which habitat type is preferred amongst V. panoptes in the landscape context of Lizard Island National Park.

Study transects were conducted over the course of one month measuring abundance of V. …

Climate Services: The Business Of Physical Risk, Madison Condon

Faculty Scholarship

A growing number of investors, insurers, financial services providers, and nonprofits rely on information about localized physical climate risks, like floods, hurricanes, and wildfires. The outcomes of these risk projections have significant consequences in the economy, including allocating investment capital, impacting housing prices and demographic shifts, and prioritizing adaptation infrastructure projects. The climate risk information available to individual citizens and municipalities, however, is limited and expensive to access. Further, many providers of climate services use black box models that make overseeing the scientific rigor of their methodologies impossible— a concern given scientific critiques that many may be obfuscating the uncertainty …

Diverse Portfolios: Investing In Tributaries For Restoration Of Large River Fishes In The Anthropocene, Kristen L. Bouska, Brian D. Healy, Michael J. Moore, Corey G. Dunn, Jonathan J. Spurgeon, Craig P. Paukert

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Rehabilitation of large Anthropocene rivers requires engagement of diverse stakeholders across a broad range of sociopolitical boundaries. Competing objectives often constrain options for ecological restoration of large rivers whereas fewer competing objectives may exist in a subset of tributaries. Further, tributaries contribute toward building a “portfolio” of river ecosystem assets through physical and biological processes that may present opportunities to enhance the resilience of large river fishes. Our goal is to review roles of tributaries in enhancing mainstem large river fish populations. We present case histories from two greatly altered and distinct large-river tributary systems that highlight how tributaries contribute …

Baldcypress (Taxodium Distichum) And Their Growth And Development Under Abiotic Stressors Related To Restoration Efforts, George Washburn

LSU Doctoral Dissertations

Baldcypresss (Taxodium distichum (L.) Rich.) forests are crucial to the Southeast coastal region for the trees’ ecosystem services. Many organizations have been trying to restore the ghost and dead forests found throughout the Gulf region through restoration events. Baldcypress seedlings and saplings face several abiotic and biotic stressors, including but not limited to elevated levels of salinity, nutrients, temperature, and light intensity. These stressors can be the limiting factor in the success or failure of these massive planting efforts.

To assess which stressors were of most concern to the restoration efforts, we conducted common garden experiments with baldcypress seedlings …

Information About Historical Emissions Drives The Division Of Climate Change Mitigation Costs, Alessandro Del Ponte, Aidas Masiliūnas, Noah Lim

Political Science Faculty Articles and Research

Despite worsening climate change, the international community still disagrees on how to divide the costs of mitigation between developing countries and developed countries, which emitted the bulk of historical carbon emissions. We study this issue using an economic experiment. Specifically, we test how information about historical emissions influences how much participants pay for climate change mitigation. In a four-player game, participants are assigned to lead two fictional countries as members of either the first or the second generation. The first generation produces wealth at the expense of greater carbon emissions. The second generation inherits their predecessor’s wealth and negotiates how …

Dynamic Characteristics Of Aerosol Optical Properties Over Dibrugarh City In The North-Eastern Indian Region During 2018–2021, Akshansa Chauhan, Shukla Acharjee, Ramesh P. Singh, Brent N. Holben

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Aerosols play an important role in the earth's environment across the globe through their involvement in various earth system cycles. The change in the aerosol properties may cause short and long-term impacts, the knowledge of such changes is useful in the estimation of the pollution sources of any region. We have carried out the analysis of the aerosols' optical and radiative properties using AERONET station data from 2018 to 2021 in Dibrugarh City. The higher Aerosol Optical Depth (AOD) values during winter and pre-monsoon months indicate high anthropogenic activities, and biomass burning in Dibrugarh. The impact of various sources and …
