abstract: Grassland habitat restoration activities are occurring within the semi-arid grasslands of the Agua Fria National Monument located 65 km north of Phoenix, AZ. The goal of these restoration activities is to reduce woody species encroachment, remove lignified plant materials and recycle nutrients within the ecosystem thus improving range conditions for both wildlife species and livestock. Broadcast burning, juniper thinning and slash pile burns are the principle tools used to accomplish resource objectives. Line cover, belt transect, densities, heights and biomass of vegetation data were collected to determine the response of the vegetative community to habitat restoration activities. Principal Component Analysis (PCA) was used to reduce data analysis to the more influential factors. Regression analysis was conducted for statistically significant response variables. Quadratic regression analysis found low predictive values. In broadcast burn treatment units, all important factors as identified by PCA had low predictive factors but significantly differed (R2 <0.01, p<0.05) between unburned and the years post treatment. Regression analysis found significant, albeit weak, relationships between time since treatment and independent variables. In pile burn treatment units, data reduction by PCA was not possible in a biologically meaningful way due to the high variability within treatment units. This suggests the effect of juniper encroachment on grassland vegetation persists long after junipers have been cut and burned. This study concluded that broadcast burning of the central Arizona grasslands does significantly alter many components of the vegetative community. Fuels treatments generally initially reduced both perennial woody species and grasses in number and height for two year post fire. However, palatable shrubs, in particular shrubby buckwheat, were not significantly different in broadcast burn treatment areas. The vegetative community characteristics of juniper encroached woodlands of central Arizona are unaffected by the removal and burning of junipers aside from the removal of hiding cover for predators for multiple years. It is recommended that habitat restoration activities continue provided the needs of wildlife are considered, especially pronghorn, with the incorporation of state and transition models specific to each of the respective ecological site descriptions and with the consideration of the effects of fire to pronghorn fawning habitat. / Dissertation/Thesis / M.S.

abstract: Many wildlife species that are essential to human livelihoods are targeted with the aim of extracting short-term benefits. Overexploitation, resulting from failed common-pool resource governance, has endangered the sustainability of large animal species, in particular. Rights-based approaches to wildlife conservation offer a possible path forward. In a wildlife market, property rights, or shares of an animal population, are allocated to resource users with interests in either harvest or preservation. Here, I apply the Social-Ecological Systems (SES) framework (Ostrom, 2009) to identify the conditions under which the ecological, social, and economic outcomes of a conservation market are improved compared to the status quo. I first consider three case studies (Bighorn sheep, white rhino, and Atlantic Bluefin tuna) all of which employ different market mechanisms. Based on the SES framework and these case studies, I then evaluate whether markets are a feasible management option for other socially and ecologically significant species, such as whales (and similar highly migratory species), and whether market instruments are capable of accommodating non-consumptive environmental values in natural resource decision making. My results suggest that spatial and temporal distribution, ethical and cultural relevance, and institutional histories compatible with commodification of wildlife are key SES subsystem variables. Successful conservation markets for cross-boundary marine species, such as whales, sea turtles, and sharks, will require intergovernmental agreements. / Dissertation/Thesis / M.S. Biology 2014

Research has long recognized and studied the dynamics of groundwater processes. More recently, groundwater dependent ecosystems (GDEs) are being recognized for their diversity and vulnerability to anthropogenic impact. Groundwater in karst landscapes presents a distinctive situation where flow through the subsurface often moves rapidly on the scale of days and weeks as opposed to years or millennia in other systems. This distinctive situation of karst systems and their vulnerability to human impacts necessitate an integrated and multifaceted approach for the management of these important resources. However, development of such an approach is complicated by the difficulty of obtaining detailed data about the ecosystem, especially in remote areas of developing countries. Additionally, management difficulties related to political boundaries, jurisdictions, and land ownership can result in ineffective and inconsistent policies and practices across a single catchment. In order to address these issues, this dissertation creates a new composite model for groundwater dependent ecosystem (GDE) management in areas of karst development. Within this new composite model, the combination of the Karst Disturbance Index (KDI) and groundwater vulnerability mapping recognizes both human disturbance and how the physical nature of the karst will enhance this impact. These studies bridge the gap between science and management by connecting the final model to management strategies for a sub-catchment of the Rio la Venta watershed, the majority of which is within the Reserva de la Biosfera Selva el Ocote in Chiapas, Mexico. This composite model serves as an adaptable spatial tool for management planning and protection for all components of the karst environment.

Sweden is the leading mining country in Europe and the Swedish government intends to retain this position by fostering innovation, investments and cooperation. However, mining is an extractive industry with massive consequences on the surrounding environment and the people living there. In resource abundant northern Sweden mineral extraction is a contested subject, not least in respect to the traditional land use by the Sami population. This study intends to increase the understanding of the current mining trial process in Sweden, the effects on sustainable regional development and the implications for local communities. To do so, this study aims to identify which aspects that are brought forward during the trial for exploitation concession and how different interests are evaluated. For the purpose of this study, the bureaucratic mining trial process is examined and 15 mining cases studied in detail considering the exploitation concession phase. The material indicates that conflicts over the bureaucratic process is based both in what aspects that should be included in the assessment, how these aspects are evaluated and at what stage in the formal process various aspects should be brought up. Guided by the concepts of extractivism and subnational resource curse, the main finding identified is that the mining trial process is state-centred. This is displayed in the limited influence of local actors on the decision and in the use of national interest as a policy tool to evaluate conflicting land use claims. These characteristics can in turn increase the risk of a subnational resource curse in northern Sweden.

Water resources are becoming increasingly important to protect, but doing so has proven challenging due to the complex nature of resource management. Many researchers have been trying to develop “usable science” to aid in this endeavor, and one method of this is the development of decision support systems. This has led to the employment of this method as a potential tool for decision makers, scientists, and the interested public to use; yet little literature is available on the success of their implementation. This study attempted to fill the gaps by gathering data through surveys and interviews from stakeholders who are part of institutions that fund the University of South Florida’s Water Atlas. The study found that the tool was used for both educational outreach and scientific research support. Decision making was mostly supported through the program’s use as a research tool. Stakeholders also expressed that conditions found in the literature to contribute to successful implementation were largely met through the Water Atlas development process and continued use.

abstract: This dissertation addresses empirical, applied, and theoretical issues in the place literature through an ethnographic study of the volunteer stewards in the nonprofit McDowell Sonoran Conservancy (Scottsdale, Arizona). The first phase of study explores Conservancy stewards’ phenomenological place meanings through participant observation, a photovoice protocol (N=18), and life-history interviews (N=53). Findings indicate that being a steward fosters deep, identity-based place meanings within the conservation land (the McDowell Sonoran Preserve) and City of Scottsdale. The second phase of study measures stewards’ psychometric place attachments to the Preserve and broader community using the Place Attachment Inventory (PAI) survey. New stewards’ (N=29) PAI scores—collected before attending orientation and one year after—demonstrate a rise in Preserve place attachment and place identity in the first year of service. Established stewards’ (N=275) PAI data suggests no correlation between place attachment and volunteer intensity. These findings are complemented by phase I results and suggest that stewards experience a rise in place identity after earning the identity of an environmental steward, regardless of engagement. The third phase of study experimentally combines the data from established stewards who participated in phase I and II (N=48) to test the hypothesis that those with identity-based place meanings would possess higher place identity scores. Data analysis found no significant differences in place identity scores between those with and without a Predicted High Place Identity. The outcomes of this experiment suggest construct validity issues with the widely used place attachment and place identity constructs. While it is established that volunteers arrive at an organization with a strong sense of place, this study demonstrates empirically how place attachments increase and place meanings deepen further after joining a volunteer organization. Communities and organizations can learn from the Conservancy’s practices that help stewards easily establish and perform a place-based steward identity. Finally, the experimental mixed methods findings suggest a sense of place research program that measures attachment to a place’s meanings rather than attachment to a place. This shift will allow place meaning and place attachment to be studied concurrently, advancing the sense of place construct and broader place theory. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2020

Social-ecological change has driven smallholder farmers throughout the world to employ a diverse array of adaptation strategies. Social, economic, and cultural factors along with environmental changes have been widely studied as determinants of adaptation decision-making. Increasingly, scholars are also examining the role of values in these decisions. Many have posited that adaptation to social-ecological change will necessitate tradeoffs of these values; however, little empirical work has been done to identify and examine these tradeoffs. In response to this gap, we first identify how farmers and fishers adapted to multiple social-ecological stressors in northwestern Pakistan. Second, we investigate how social-ecological factors, perceived changes, and perceived costs influence adaptation decision-making and adaptive capacity. Third, we examine the role of and tradeoffs between values in adaptation decision-making. Based on our findings, we posit that in addition to the identification of values, it is also necessary to examine values as they relate to one another, change over time, and are embedded in multi-scalar processes. This will allow us to more fully understand the factors that influence adaptation decisions and support more equitable strategies that align with stakeholders’ diverse values.

<div>Human disturbance to birds is a subject of concern for bird conservation. Bird recreationalists, such as birders and bird photographers, who actively seek out birds, are identified as a broad group of people that contribute to bird disturbance. There are few studies on birders’ and bird photographers’ perceptions and behaviors related to bird disturbance, and these studies have conflicting results. Furthermore, little research identifies why bird recreationalists engage in behavior that disturbs birds. Understanding perceptions and behavior related to bird disturbance and the context behind engaging in this behavior is important for creating comprehensive solutions for preventing disturbance to birds. The purpose of this thesis is to create a typology of bird recreationalists, based on whether they engage in birding or bird photography as primary activities; identify the socio-demographic characteristics among bird recreationalists that are connected to an increased likelihood to engage in behavior that disturbs birds; assess perceptions of blame for disturbance to birds; and identify how motivations, barriers, challenges and trade-offs are associated with following ethical birding and bird photography guidelines. </div><div><br></div><div>The thesis used an online survey and in-person interviews of birders and bird photographers in two Midwestern states in the U.S., Illinois and Indiana, to achieve these objectives. Three sub-groups of bird recreationalists were identified through the online survey: individuals who only engage in birding; individuals who primarily engage in birding and secondarily, bird photography; and individuals who primarily engage in bird photography and secondarily, birding. Our findings indicate that individuals who 1) are male, 2) only engage in birding, 3) maintain life lists, 4) have more birds on their life lists, 5) can identify more birds by sight, 6) have more years of experience or 7) have a higher level of achievement-oriented motivation are more likely to engage in potentially harmful behaviors to birds. Additionally, quantitative findings suggest that birders and bird photographers may not perceive themselves as main contributors to bird disturbance. </div><div><br></div><div>The qualitative portion of the research identifies multiple ethical birding and bird photography guidelines that recreationalists found challenging to follow that had both ecological (e.g., maintaining distance) and social (e.g., respectfully educating others) implications. Recreationalists identified listing, photographing and seeing birds as key motivations to breaking ethical guidelines. Barriers to following guidelines included apathy, ignorance and improper technology. Finally, recreationalists identified bad photography and missed experiences as major trade-offs associated with following ethical guidelines. he concepts explored in this thesis research provide important management implications for natural resource managers and stakeholders in bird conservation and suggest a further need for examining bird recreationalists’ decision-making around bird disturbance.</div>

Liming has been used extensively in Sweden, but the management success has been only partial, mostly mitigating the impact of acidification rather than restoring the ecological communities to a self-maintaining pre-acidified state. Rather than a sound restoration tool, liming is a form of command-and-control management that comprises a significant disturbance in the system, which manifests in the form of profound alterations of biophysical settings of lakes. This thesis aims to assess biological responses to liming with a special focus on resilience by looking at the cross-scale interaction aspects of littoral invertebrate communities in limed lakes within the framework of panarchy theory. The thesis is based on multivariate time series modeling (AEM-RDA) to extract hierarchical temporal fluctuations patterns (temporal scales) in littoral invertebrate communities. This analysis tested for the premise of panarchy theory that complex systems are hierarchically structured. Time series analyses were followed by Spearman rank correlation analysis to test another premise of panarchy theory; namely, that “information” (e.g., management interventions) flows between these hierarchical scales. Specifically, Ca:Mg ratios were used as a surrogate of liming, and correlated with each temporal pattern identified by the AEM-RDA. The result showed the distinct temporal scales in littoral invertebrate communities in limed lakes, fitting the premises of panarchy theory and agreeing with previous studies that found hierarchical temporal organizations in other lake communities. The correlation analyses indicated weak cross-scale manifestation of Ca:Mg ratios in the littoral invertebrate communities, suggesting a weak information flow of liming in managed lakes. This “dilution” of management may provide one mechanism that could explain why liming is not effective in creating a self-organizing, resilient system. The results of this study allow shedding further light on liming as a coerced regime (degraded complex systems forced into a state of desired conditions (e.g., ecosystem service provisioning) through constant management). Most research has so far focused on the evaluation of traditional metrics of biodiversity, which have shown that community structure is substantially altered in limed lakes, deviating from those in circumneutral reference lakes and degraded acidified lakes. This thesis, therefore, concludes that integration of traditional ecological approaches and complexity studies may provide complementary insight into the organization of ecosystems and sustainable resource management.
