The Effects of Simulated <i> Spermophilus Franklinii </i> Burrowing on Prairie Soil Invertebrate Communities
… have ecological effects on overlying vegetation, invertebrate communities, and surrounding soil characteristics. Franklin’s ground squirrel (<em>Spermophilus franklinii</em>) is a declining, tunneling mammal species previously found throughout Central Illinois. Preference for natural tallgrass …

Effects of neonicotinoids and fungicides on soil invertebrate communities and litter decomposition within restored prairie
… and fungicides can greatly impact the health of soil invertebrate communities. My study compares soil fauna community composition, abundance, species diversity, and litter decomposition across restored prairie plots treated with a neonicotinoid (clothianidin) and a fungicide (Captan). Soil …

Changes in soil invertebrate decomposer communities during regeneration of Scots Pine within the Abernethy Forest Reserve, Scotland
… an expansion on birds, mammals and above ground invertebrates have been previously been investigated, but little consideration has been given to soil invertebrates. This research looks at effects of Scots pine (Pinus sylvestris) regeneration on the meso- and macro- soil invertebrate communities. …

Exploring Diversified Vineyard Ecological Soil Management Strategies: Impacts of cover cropping, Spanish River Carbonatite, and smooth pigweed (Amaranthus hybridus) interactions on an agroecosystem
… agroecosystems has led to global degradation of soil and reduced biodiversity, two of the major challenges faced by agriculture today. Soil, the foundation of an agroecosystem, forms the base for cropping systems and how it is managed matters. My research focused on investigating how two …

Disentangling Perceived and Measured Soil Health in New York City Urban Farms
Soil contamination is often addressed by constructing new compost-based soils for urban agriculture. We examined these constructed soils to assess soil health across a diversity of farming sites across New York City, consulting with farmers to characterize their soils as “healthy” or “unhealthy” …

Interactive Effects of Cover Crops, Invertebrate Communities and Soil Health in Corn Production Systems
… on a systems level. Encouraging biodiversity and soil health is the goal of many agricultural practices used in regenerative farming; regenerative systems employ practices which abide by the two main principles of increasing biodiversity and decreasing disturbance, with the goal of encouraging …

Assessment of Petroleum Hydrocarbon Contamination In Terrestrial Ecosystems Using Conventional and Novel Approaches
… to assess the toxicity of weathered PHC-impacted soils to native organisms, improve the efficiency and accuracy of current toxicological tests, and identify molecular biomarkers in a model springtail species, Folsomia candida, suitable for high-throughput toxicity testing. Weathered …

The effects of accelerated soil acidification on aggrading temperate deciduous forests: The Fernow Experimental Forest Long Term Soil Productivity (LTSP) Study at 13 years
… I used the Fernow Experimental Forest Long Term Soil Productivity (LTSP) experiment near Parsons, WV to determine how ongoing acidic deposition may affect total ecosystem carbon (C) storage, stand level dynamics, and soil and foliar chemistry in a young regrowing temperate deciduous forest. I …

Ecosystem goods and services in semi-arid lanscape : an examination of the relationship between ecological processes, land-use strategies and biodiversity conservation
… speeds reduced four fold, and eight times less soil lost to wind erosion in natural vegetation compared with transformed areas. However, in managed transformed areas, rainfall infiltration was greater than in natural and transformed areas. An examination of the key ecological processes …
