Pheonolgy And Climate Change In The Tw Daniel Experimental Forest Meadow, Elise Riley
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 …
Do Aspen Stands Reduce Fire Severity And Stop Fire Spread?, Elyse Doty
Do Aspen Stands Reduce Fire Severity And Stop Fire Spread?, Elyse Doty
Student Research Symposium
Aspen stands are widely thought to behave as fire breaks, reducing fire severity and preventing fire spread. However, this prevailing belief has not been well studied. With larger more intense fires in recent decades and further projected changes in fire behavior for the future, having a better understanding of how aspen trees and stands interact with fire would be valuable for forecasting how our forests will respond to climate change and disturbance in the future. In addition, forest managers in Utah and other regions of the Intermountain West conduct aspen restoration treatments for multiple objectives, including fire mitigation. To quantify …
Effect Of Spatial Influence On Endophyte Diversity Within Alnus Rubra, Sebastian L. Singleton
Effect Of Spatial Influence On Endophyte Diversity Within Alnus Rubra, Sebastian L. Singleton
Student Research Symposium
Red alders (Alnus rubra) of the Pacific Northwest are characterized as actinorhizal dicotyledons; plants that possess that ability to form symbiotic relationships with endophytic organisms, which result in nitrogen-fixing nodules. In Alders of the order Fagales, such a symbiotic relationship with Frankia bacteria allows these plants to play crucial environmental roles as pioneer species able to colonize and enrich nutrient-deficient soils. This ability has a major impact on ecological succession by enabling other species to establish. Although inoculation with frankia bacteria is known to increase symbiotic nitrogen fixation capabilities of actinorhizal plants, whether they could confer the same benefit to …
