Effect Of Initial Infestation Of Zebra Mussels On Freshwater Drum Diets In Red Lake, Mn, Marissa M. Pribyl

Journal of Earth and Life Science

Zebra mussel Dreissena polymorpha veligers were first found in the Red Lake system in Beltrami County in 2017, however no adult zebra mussels have been documented. When zebra mussels first invade a system, fish often switch their prey use to this new abundant resource. Freshwater drum Aplodinotus grunniens is one of these fish species known to consume physidae and bivalves, including zebra mussels, using pharyngeal teeth, the molar-like grinders in the back of their throats. This research aims to identify any presence of adult zebra mussels in the system and determine freshwater drum diet composition and feeding patterns by analyzing …

Fostering Socio-Ecological Resilience To Wildfire By Interconnecting Knowledge Systems At Cal Poly Humboldt, Jeffrey M. Kane, Erin Kelly, Benjamin Graham, David Greene

Humboldt Journal of Social Relations

The wildfire-related challenges of Northern California and many other regions in the western United States are daunting in scope and magnitude. Ecologically and culturally salient solutions that limit the negative impacts of wildfire and promote resilience of human and ecological systems will require newer approaches. Through Cal Poly Humboldt and the Fire Resilience Institute, there is greater emphasis on the interconnection of knowledge systems across education, training, research, and management. Here we highlight several on-going efforts that seek to enhance the fire resilience workforce, promote socio-ecological resilience through interdisciplinary projects, and inform management through monitoring and research projects that intentionally …

Effects Of Translocation On Eastern Black-Tailed Rattlesnakes (Crotalus Ornatus) In The Northern Chihuahuan Desert, Jacob A. Coffman

Lewis Honors College Thesis Collection

AS HUMANITY continues to grow and expand, we inevitably encroach on wildlife habitat. This can create conflict between humans and wildlife. Human wildlife conflict usually occurs when humans are near areas where wildlife typically reside. A prime example is a farmer coming into conflict with animals that predate their seeds or livestock. The most common response to this problem in many areas is lethal control to prevent economic loss (Dickman 2010). This seems like an immediate resolution of the conflict in the human’s perspective, but this action can have many adverse effects. This killing may result in negative social outcry, …

Have Rusty Crayfish Affected The Diets Of Yellow Perch?, Matthew D. Kvam

Journal of Earth and Life Science

Freshwater ecosystems are some of the most susceptible to invasive species. It is one of the reasons they face the highest levels of species endangerment. Rusty crayfish Faxonius rusticus are one such invasive species, they fragment food webs and negatively affect native species. However, it seems as though native species are beginning to rely on them as a source of food. Yellow perch Perca flavescens, an important forage and game species, is one such species that is highly affected by these invasions. At smaller sizes yellow perch primarily feed on invertebrates whose populations are degraded by rusty crayfish. Therefore, the …

Biomechanics Of Mantis Prey Capture, Danielle S. Taylor

Honors Theses

Mantis species have a variety of different morphologies, so do the extreme forms of mantis limbs trade prey catching capability for camouflage? We hypothesize that some extreme forms of mantis limbs that are associated with cryptic species may be associated with a tradeoff of the capability of those limbs. Previous research has developed 2D morphologies of several hundred species of mantises. We are creating a 3D morphology by using micro dissection, micro CT imaging to construct our 3D biomechanical model. We found the attachment points of the ligaments and muscles from a Tenodera forearm and have constructed a 2D biomechanical …

Conservation Easements: A Tool For Preserving Wildlife Habitat On Private Lands, Robin M. Rotman, Sarah A. Brown, Michael A. Powell, Sonja A. Wilhelm Stanis

Faculty Publications

Conservation easements are an essential tool for conserving private lands, and they have great potential for enhancing wildlife habitat and biodiversity. Private land conservation in the United States is likely to increase in the coming years, in light of Executive Order No. 14,008, issued by President Joseph Biden on January 27, 2021, which set a goal of conserving at least 30% of U.S. lands and waters by 2030 (Executive Office of the President 2021). There is, therefore, a need to evaluate the effect of conservation easements on wildlife habitat and biodiversity and to make recommendations for further enhancing the effectiveness …

Predators In Paradise: Ecotourism And Predator-Prey Dynamics In Monteverde, Costa Rica, Andrew Cremeans

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The use of camera trap surveys is increasingly common to investigate recurring diel activity of mammals. Investigation into the temporal overlap of mammals can provide unique insights into predator-prey dynamics. Understanding this relationship is essential to effectively manage and conserve both species. Extensive research across the tropics has found that daily activities of mammals were shaped by thermoregulation and trophic location in food webs. Although broad scale studies of daily patterns of mammals have enhanced our understanding of these constraints, many study sites included were remote protected areas under strict conservation measures. Such protected areas often had full complements of …

Insect Biodiversity Of Select Areas In The Western Suburbs Of Chicago, Bradley Dawson

Department of Entomology: Distance Master of Science Projects

Introduction

Insects make up an integral part of the landscape in North America and across the world. They occupy a myriad of niches in food webs, function as predators and prey, and provide environmental services like pollination of flowering plants and decomposition of dead animal carcasses and fecal matter. They take part in ecosystems that are often delicately balanced, and so conservation is often a worthwhile effort in areas that would otherwise be trampled by human activity. In the western suburbs of Chicago, Illinois where I reside, there is a mix of both heavily developed areas as well as some …

Bat Activity And Insect Biomass On Mcconnell Airforce Base Compared To Surrounding Wichita Parks, Michaela Sielaff

Master's Theses or Doctor of Nursing Practice

Bats are bioindicators of the communities to which they belong, giving researchers insight into the overall health of those ecosystems. Bats are also very adaptable and are capable of tolerating urbanization. Some species, such as Lasiurus borealis and Lasionycteris noctivagans may even benefit from adjacent industrial and commercial land use, although this is not the case for all bat species. In 2021, we began acoustic and mist net surveys of bats at McConnell Air Force Base (MAFB, or “base”) in Wichita, KS. However, no bats were captured or seen during mist net surveys, although some were detected acoustically over a …

Biodiversity Of Philippine Marine Fishes: A Dna Barcode Reference Library Based On Voucher Specimens, Katherine E. Bemis, Matthew G. Girard, Mudjekeewis D. Santos, Kent E. Carpenter, Jonathan R. Deeds, Diane E. Pitassy, Nicko Amor L. Flores, Elizabeth S. Hunter, Amy C. Driskell, Kenneth S. Macdonald Iii, Lee A. Weigt, Jeffrey T. Williams

Biological Sciences Faculty Publications

Accurate identification of fishes is essential for understanding their biology and to ensure food safety for consumers. DNA barcoding is an important tool because it can verify identifications of both whole and processed fishes that have had key morphological characters removed (e.g., filets, fish meal); however, DNA reference libraries are incomplete, and public repositories for sequence data contain incorrectly identified sequences. During a nine-year sampling program in the Philippines, a global biodiversity hotspot for marine fishes, we developed a verified reference library of cytochrome c oxidase subunit I (COI) sequences for 2,525 specimens representing 984 species. Specimens were primarily purchased …

The Long-Term Effects Of Wildfire Severity On Oak-Pine Communities And Their Microclimates, Scott Glenn Culbert

Theses and Dissertations--Forestry and Natural Resources

In the eastern U.S., fire-dependent tree species have historically dominated upland forest communities, but are now experiencing widespread regeneration challenges as a result of 20^th century fire suppression policies, and are being replaced by mesophytic species. Wildfires that contain areas of high burn severity may provide an important means of mitigating these challenges and facilitating fire-dependent species regeneration and recruitment into larger size classes. One mechanism by which high-severity fire can accomplish this is by modifying understory microclimate characteristics to be more conducive to these species’ growth. A wildfire within the Daniel Boone National Forest, Kentucky, USA, provided the …

Effects Of Forest Reclamation And Landscape Features On Avian Occupancy, Species Richness, And Abundance In Appalachia, Rebecca N. Davenport

Theses and Dissertations--Forestry and Natural Resources

The Forestry Reclamation Approach (FRA) is a recently developed coal mining reclamation method that emphasizes best management practices in forestry, such as the planting of native trees and shrubs. Although the FRA is expected to benefit wildlife, no studies have empirically examined the effects of the FRA on avian species. My study aimed to identify which reclamation approaches and/or landscape features promote breeding songbirds, particularly mature forest avian guilds and species of conservation need. I conducted point count surveys in the Appalachian Mountains of eastern West Virginia and assessed differences in avian occupancy, species richness, and species abundance between four …

Pond-Breeding Amphibian Responses To Wetland Creation And Reforestation On A Legacy Surface Mine In The Monongahela National Forest, Lauren Breanna Sherman

Theses and Dissertations--Forestry and Natural Resources

Surface mine reclamation has been an evolving practice since the Surface Mining Control and Reclamation Act was passed in 1977, holding mining companies accountable for returning ecological function to areas directly impacted by mining activities. One recent method of reclamation, the Forestry Reclamation Approach (FRA), aims to enhance reforestation and ecosystem function through the creation of wetlands, as opposed to traditional methods that often revert land to grasslands. However, wildlife response to FRA has rarely been investigated. The goal of this project was to analyze the effects of the four treatment types, FRA in two chronosequences, natural regeneration, and unmined …

Evaluation Of Autonomous Recording Unit Performance In Detecting Black-Billed Cuckoos, Jenna L. Asnault

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Black-billed Cuckoos (Coccyzus erythropthalmus) are classified as a species of concern in Montana and have declined due to habitat loss and fragmentation. Cuckoos are challenging to study, as they do not move or call frequently in the presence of people. This makes researching and managing these birds difficult. Autonomous acoustic survey methods offer the potential to be more effective than traditional avian survey methods. Autonomous recording units (ARUs) are small, programmable, relatively inexpensive acoustic detectors, and have been used in several other studies. Cuckoos, however, nest and perch in dense riparian vegetation, potentially limiting the detection capabilities of …
