Interspersed Denuded Zone (Idz): How Patchy Leaf Litter Dynamics In A Buckthorn-Invaded Urban Woodland Can Affect Microarthropod Species Richness, Angela Stenberg
Interspersed Denuded Zone (Idz): How Patchy Leaf Litter Dynamics In A Buckthorn-Invaded Urban Woodland Can Affect Microarthropod Species Richness, Angela Stenberg

Biodiversity loss may serve as a key diagnostic of the Anthropocene. An important driver of this loss is by means of invasive species. In this study of a forest preserve in Chicago, Illinois we examined Interspersed Denuded Zones (IDZs for short), which are areas of patchy leaf litter in invaded forests caused in this case by the rapid decomposition of litter from buckthorn (Rhamnus cathartica). We characterized the leaf litter mass in IDZs and enumerated litter-inhabiting microarthropod populations. We found that plots of high buckthorn density are associated with IDZs: there was significantly less leaf litter mass in …

The urban ecosystems we inhabit provide essential ecosystem services to humans, such as air pollution removal, as well as effective means to avoid costs related to urban development, such as stormwater treatment. A better understanding of the value of ecosystem services and their spatial distribution in urban areas is vital to widespread, wholistic understanding of the relationship of environmental, economic, and social conditions. As such, it should be a component of education in grades 6-12, college, and continuing education. i-Tree Landscape is a free, online model developed by the USDA Forest Service in which users can select a geography (i.e. …
The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry
The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry
DePaul Discoveries
Biogenic volatile organic compounds (BVOC) are the second-most abundant reactive gasses emitted into the atmosphere by the biosphere. Isoprene is a BVOC produced by the process of photosynthesis from vegetation and is emitted from plant leaves. Isoprene is a hydrocarbon that combines with oxides of nitrogen in the atmosphere to create ozone in the troposphere, an air pollutant. Invasive trees alter ecosystems and affect native tree populations. Invasive tree species in the Chicagoland area are outcompeting native tree species and expanding rapidly. The effect of isoprene emissions on air quality is a well-researched area in the atmospheric science community, however, …
