A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …

Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, Emily M. Stanevicius

Celebration of Learning

Morel mushrooms, Morechella esculenta and M. deliciosa, are known delicacies across the globe, ranging from exquisite dishes in French cuisine to Eastern palates such as Japanese Matsutake. According to literature, true morels diverged as their own genus about 129 million years, again which has led to the development of more than 177 species and have been part of the human diet since their beginning. However, the elusiveness of morels has contributed to the mushrooms infamy for rarity, and has even been known to sell for more than $40 per pound. This project seeks to aid in the search for morels …

Effect Of Different Miracle-Gro Concentrations On The Growth Of Wisconsin Fast Plants, Eric D. Shershen, Nicholas M. Orslini, David Channon, Marvin Agyeben

Celebration of Learning

The Wisconsin Fast Plant, Brassica rapa (Brassicaceae) seeds were planted in three, six-celled containers and were filled with standard potting soil under continuous grow-lux lighting. After the first week of plant growth, E1and E2 were placed in a separate trays and given 1.0 and 1.5x the recommended amount of Miracle-Gro formula, respectively. The control was left in tap water and all were kept in 1 cm of solution. Every seven days the plants’ heights were recorded, and the total number of flowers were counted. By the fourth week, the average height of the control plants was 105.7 mm, of the …

The Effects Of Simulated Herbivory On The Growth Of Wisconsin Fast Plants, Jessica Joerger, Tanner Logan, Kiefer Kious, Jake Rancic

Celebration of Learning

Wisconsin Fast Plant (Brassica rapa, Brassicaceae) seeds were planted in three six-celled containers with 15 seeds in each tray. After a week of germination in standard potting soil and tap water,

we started our manipulation of simulating herbivory with scissors. E1 plants had both cotyledons of each plant removed, E2 plants had half of the cotyledons of each plant removed, and the control group was allowed to grow. E2 plants had its foliage leaves cut when they exceeded 1 cm from that week on. Every week (seven-day intervals), the height of all the plants were recorded as well as the …
