Comparisons Of Above- And Below-Ground Carbon Storage In A Northeastern Illinois Urban Forest Following Rhamnus Cathartica And Fraxinus Spp. Removal, River Sanchez-Dudik, Elene Drosos

This study focused on quantifying potential differences in ecosystem services (carbon storage, soil organic matter, macroarthropod density) in a small, partially restored urban forest in order to determine if common buckthorn and standing dead ash removal effects can be detected while restoration is on-going. We calculated aboveground carbon storage (tons/total area) using whole tree biomass equations and compared this to i-Tree Canopy estimations. We collected SOM through loss-on-ignition and collected macroinvertebrates by pitfall trapping to determine differences along transects. Aboveground carbon storage, soil organic matter, and macroinvertebrate total results for this study were found to be statistically not significant, indicating …
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 …
Investigating The Effects Of Temperature On Lesser Celandine, Regina Bellian
Investigating The Effects Of Temperature On Lesser Celandine, Regina Bellian
The Downtown Review
This paper explores invasive species Ficaria verna (Lesser celandine) and the effects of temperature on its growth. Trials were completed with two treatments, 13OC cold temperature and 20OC ambient temperature. Germinated bulbils of Lesser celandine were planted on February 15, 2017 and placed in their respective growing chambers. The plants were watered weekly and monitored for growth until harvest on March 29, 2017. Upon harvest, the plants’ height, largest leaf diameter and biomass were measured after extraction from soil and the removal of the leftover soil debris. Average height was found to be 11.66cm for the cold treatment and 5.14cm …
Comparative Study Of Photosynthesis Rates Between Native Red Maple And Invasive Norway Maple In The Eastern Deciduous Forest, Evan M. Bourtis, Lindsey R. Heckman
Comparative Study Of Photosynthesis Rates Between Native Red Maple And Invasive Norway Maple In The Eastern Deciduous Forest, Evan M. Bourtis, Lindsey R. Heckman
The Review: A Journal of Undergraduate Student Research
Invasive species, such as the Norway Maple, are often able to outcompete native species, such as the Red Maple by performing more efficiently in the environment compared to the native species. In this study, we examined if the Norway maple was able to outcompete the Red Maple in the Eastern Deciduous Forest because the Norway Maple had a higher rate of photosynthesis. The study found that the Norway Maple leaves had a slightly higher rate of carbon dioxide consumption than Red Maple leaves and that the Red Maple leaves had a higher rate of oxygen production compared to the Norway …
Phragmites Removal Increases Property Values In Michigan’S Lower Grand River Watershed, Paul Isely, Erik E. Nordman, Shaun Howard, Richard Bowman
Phragmites Removal Increases Property Values In Michigan’S Lower Grand River Watershed, Paul Isely, Erik E. Nordman, Shaun Howard, Richard Bowman
Journal of Ocean and Coastal Economics
The presence of Phragmites australis, an invasive wetland plant, negatively affects coastal property values and home prices rise with distance from Phragmites. Home prices increased as distance to Phragmites increased at a rate of $3.90/meter. Removing Phragmites from a property so that the next closest Phragmites was 400 m away results in a property value increase of over $1,500. Removing all Phragmites within 400 m of any property results in a total property value impact of $837,000. This generates about $13,457-$15,121 in additional property taxes each year once the prices and taxes adjust to the plant’s removal. We …
Population Dynamics Of Parthenium Hysterophorus (Asteraceae) And Its Biological Suppression Through Cassia Occidentalis (Caesalpiniaceae), Jai Knox, Disha Jaggi, Manoj Stephen Paul
Population Dynamics Of Parthenium Hysterophorus (Asteraceae) And Its Biological Suppression Through Cassia Occidentalis (Caesalpiniaceae), Jai Knox, Disha Jaggi, Manoj Stephen Paul
Turkish Journal of Botany
Phytosociological analysis performed over 2005 to 2009 revealed that Cassia occidentalis L. is a dominant species at 3 of 4 sites in Agra district, India, that were previously observed to be dominated by heavy populations of Parthenium hysterophorus L. In order to determine the role of biomolecular interaction, i.e. the allelopathic effect, if any, on this shift of floral pattern effects, aqueous shoot and root cold leachates were determined on seed germination, shoot cut bioassay, seedling bioassay, chlorophyll, nitrogen, and protein content of P. hysterophorus. A significant reduction in germination percentage, shoot cut bioassay, seedling bioassay, and chlorophyll of P. …
