Modeling Reproduction Influencers Of An Endangered Oak, Camila Cortez Aug 2021

Modeling Reproduction Influencers Of An Endangered Oak, Camila Cortez

DePaul Discoveries

The endemic oak, Quercus brandegeei has been labeled as endangered by the IUCN Red List of Endangered Species due to its limited genetic diversity and lack of regeneration. The oak (Quercus) species is a keystone species in many parts of the world and has been facing various challenges to their survival (Westwood 2017) making efforts to support and protect endemic oaks all the more ecologically and socially imperative. There are challenges to identifying threats as there are many unknown characteristics of Q. brandegeei’s biology that are essential to carrying out conservation efforts. To develop a greater understanding of …


I-Tree Landscape: A Case Study In Best Practices For Education And Dissemination For Multiple User Groups, Margaret M. Abood May 2018

I-Tree Landscape: A Case Study In Best Practices For Education And Dissemination For Multiple User Groups, Margaret M. Abood

DePaul Discoveries

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 Jul 2017

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, …
