Pheonolgy And Climate Change In The Tw Daniel Experimental Forest Meadow, Elise Riley Apr 2021

Pheonolgy And Climate Change In The Tw Daniel Experimental Forest Meadow, Elise Riley

Student Research Symposium

As the earth’s climate warms many plant species are experiencing phenological stages (the timing of their seasonal life cycle events) earlier than they previously have. Dangers of phenological stages occurring earlier in the year include a greater risk of frost kill and the possibility of the speciation of already small populations, both of which could make species more susceptible to extinction. This research focused on determining if meadow forb species within Utah State University’s TW Daniel Experimental Forest (TWDEF) have experienced earlier phenology -specifically, earlier flowering dates- over the past 52 years. Historical phenological data was obtained from journals kept …

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 …
