Aspen Bibliography

The reliance of 10 Utah (USA) aspen forests on direct infiltration of growing season rain versus an additional subsurface water subsidy was determined from a trait- and process-based model of stomatal control. The model simulated the relationship between water supply to the root zone versus canopy transpiration and assimilation over a growing season. Canopy flux thresholds were identified that distinguished nonstressed, stressed, and dying stands. We found growing season rain and local soil moisture were insufficient for the survival of 5 of 10 stands. Six stands required a substantial subsidy (31–80% of potential seasonal transpiration) to avoid water stress and …

Jerome Powell Is Not The Bad Guy, Timothy Meyer

Cornhusker Economics

One of the maxims often heard in economics, agriculture, and politics is that those who do not learn from history are bound to repeat it. At first glance, this is a pessimistic view of human behavior. However, I believe that in some part it is a reflection of the positive spirit exhibited by many Americans. While it is true some have not bothered to learn from history, others have simply emphasized the positive times while simultaneously limiting the memory of more challenging experiences.

Societal Rebirth: The Importance Of Spirituality, Lauren Rothstein

English Department: Traveling American Modernism (ENG 366, Fall 2018)

This article offers an exploration of what the social consequences are when modernity strips away religious-human relationships to the land. The two texts Black Elk Speaks and Grapes of Wrath both include moments of anonymous forces imposing systematic modernization on society. Particularly, I try to understand the controversial subject of societal rebirths, traditionally defined through employment and steady food source availability. This paper proposes an approach to societal rebirths that emphasizes the importance of spiritual connection to the land through a critical analysis of Bakhtin's theory of Chronotope and Leopold's theory of Land Ethic. On the issue of spiritual connection …

Recoupling Fire And Grazing Reduces Wildland Fuel Loads On Rangelands, Heath D. Starns, Samuel D. Fuhlendore, R. Dwayne Elmore, Dirac L. Twidwell Jr, Eric T. Thacker, Torre J. Hovick, Barney Luttbeg

Department of Agronomy and Horticulture: Faculty Publications

Fire suppression and exclusion, the historically dominant paradigm of fire management, has resulted in major modifications of fire-dependent ecosystems worldwide. These changes are partially credited with a recent increase in wildfire number and extent, as well as more extreme fire behavior. Fire and herbivory historically interacted, and research has shown that the interaction creates a unique mosaic of vegetation heterogeneity that each disturbance alone does not create. Because fire and grazing have largely been decoupled in modern times, the degree to which the interaction affects fuels and fire regimes has not yet been quantified. We evaluated effects of fire-only and …
