Managing For Multiple Objectives In Southwestern Forests: Evaluating The Trade-Offs Between Enhancing Mexican Spotted Owl Nest Habitat And Mitigating Potential Crown Fire, Daniel C. Deane Mckenna

All Graduate Theses and Dissertations

The Forest Inventory and Analysis (FIA), the United States’ forest census, measured sixty-six Mexican spotted owl nest stands in order gain insight into the structure and composition of the nest habitat of this threatened species. I used these data, along with the greater FIA database and the Forest Vegetation Simulator to explore questions surrounding the management of Mexican spotted owl habitat, specifically how to balance the objective of sustaining and enhancing nest habitat in face of increasing forest fire size and severity in the Southwest. My research consisted of three studies. The first study quantified the structure and composition of ...

This research develops an integrated methodology to determine the economic value to anglers of recreational fishery ecosystem services in Everglades National Park that could result from different water management scenarios. The study first used bio-hydrological models to link managed freshwater inflows to indicators of fishery productivity and ecosystem health, then link those models to anglers' willingness-to-pay for various attributes of the recreational fishing experience and monthly fishing effort. This approach allowed us to estimate the foregone economic benefits of failing to meet monthly freshwater delivery targets. The study found that the managed freshwater delivery to the Park had declined substantially ...

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro 2017 The Graduate Center, City University of New York

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

All Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space ...


The Paradigm Of Engagement: Integrating Social Science And Extension Outreach To Engage Beginning Family Forest Owners, Ian Anderson 2017 The University of Maine

The Paradigm Of Engagement: Integrating Social Science And Extension Outreach To Engage Beginning Family Forest Owners, Ian Anderson

Electronic Theses and Dissertations

Family forest owners own 36% of the forestland in the United States. These lands provide ecosystem services and natural resources to a broad community and management of these lands should be based on informed decisions. However, many family forest owners are unaware of conservation and stewardship options, and the number of unaware landowners may be increasing. A new cohort of beginning family forest owners (BFFO), who have acquired land in the past 5 years, has emerged. Programs designed to inform landowners about different management opportunities tend to attract only a small group of interested owners. In the following 2 phase ...

These scientific researches are of diverse nature; with main emphasis on improving the supply chain issues and minimizing cost of transportation, including road ...


The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry 2017 DePaul University

The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry

DePaul Discoveries

Biogenic volatile organic compounds (BVOC) are the second-most abundant reactive gasses emitted into the atmosphere by the biosphere. Isoprene is a BVOC produced by the process of photosynthesis from vegetation and is emitted from plant leaves. Isoprene is a hydrocarbon that combines with oxides of nitrogen in the atmosphere to create ozone in the troposphere, an air pollutant. Invasive trees alter ecosystems and affect native tree populations. Invasive tree species in the Chicagoland area are outcompeting native tree species and expanding rapidly. The effect of isoprene emissions on air quality is a well-researched area in the atmospheric science community, however ...
