Impacts Of Livestock Dewormers On Dung Beetle Foraging Choices Across Spatial Scales, Madison L. Kluge

Theses and Dissertations--Entomology

Dung beetles provide ecosystem services in pasture systems but are vulnerable to chemical residues in livestock dung. Parasiticides containing macrocyclic lactones (MLs) are used to control parasites in livestock and are excreted unmetabolized in dung, exposing non-target organisms to these compounds. We used a multi-scale approach to examine whether ML residues alter dung beetle foraging ecology. At the field scale, we assessed dung beetle abundance and community composition using traps baited with dung from untreated cattle and cattle treated with ivermectin, moxidectin, or eprinomectin across eight farms and natural areas. At a smaller scale, we conducted behavioral assays to quantify …

High Potential, Uneven Uptake: Off-Grid Renewables In Agriculture Across The Global South, Muhamad Setyawan Bahari, Destia Mardhotillah

Ovipositional Behavior Of The Twig Girdler (Cerambycidae: Oncideres Cingulata) On Stems Of Mockernut Hickory (Carya Tomentosa) In Arkansas, R. Tumlison, L. Serviss

Journal of the Arkansas Academy of Science

The Twig Girdler (Cerambycidae: Oncideres cingulata) is a long-horned beetle that girdles stems of certain species of trees to prepare a habitat for its offspring. The stems eventually die, break, and fall from the tree, but the beetle usually had already laid its eggs within the stems. Eggs are laid singly, almost always at growth rings or leaf bases. Because the space for the young to develop is finite, laying too many eggs could cause reproductive failure and too few eggs would be suboptimal. We hypothesized that the female laying eggs should be able to evaluate the stem and …

Layers Of Biodiversity: Linking Urban Garden Plants And Arthropods, Chenyang Su

Dartmouth College Ph.D Dissertations

Diverse arthropods play essential roles in urban agriculture, while urban agriculture provides food and habitat that support arthropod biodiversity in fragmented urban landscapes. In urban community gardens, a form of urban agriculture characterized by allotment-style gardens, arthropods interact with plants and green space across multiple spatial scales of management, from individual gardeners' plots to broad urban landscapes. Understanding how plant communities in urban community gardens and urban landscapes shape arthropod biodiversity and interactions across scales can inform both agricultural management and urban biodiversity conservation. In this thesis, I conducted a series of field studies on ecologically and economically important arthropods …

Do California Rangeland Healthy Soil Practices Offer Co-Benefits For Grassland Birds?, Ximena O. Gil

Cal Poly Humboldt theses and projects

Rangelands are important landscapes in California that support a robust cattle industry and serve as vital grassland habitat for birds. Climate change is projected to impact rangelands, leading to economic and ecological deterioration. In California, the Healthy Soils Program (HSP) incentivizes climate-smart solutions to increase working land resiliency. While the HSP targets soil and range health for livestock, it may also benefit birds. We surveyed rangeland operators to examine whether the implementation and duration of specific range management practices, such as range seeding, prescribed grazing, and silvopasture, are associated with bird community responses, using avian point count data from Point …
