Urban wildlife ecology and conservation:A brief history of the discipline

Urban wildlife ecology and conservation is a discipline worldwide in scope. Although some attention was given the subject in the early to mid-1900s, most activity in the field is of more recent origin. Many European countries have active programs and activities, including the United Kingdom-Man and the Biosphere (UK-MAB) Urban Forum and The Wildlife Trusts of England, the United Nations Educational, Scientific, and Cultural Organization's MAB Program, and urban ecology research in Germany and Poland. The Netherlands' concept of “ecological landscapes” introduced a new approach to design of urban open space. Durban, South Africa followed with “D'MOSS,” a metropolitan open space system founded on the principles of island biogeography theory. The park connector network of Singapore combines principles of conservation biology and landscape planning. Urban wildlife programs and activities exist in the United States at the federal, state, and local levels as well as in private conservation organizations. The Wildlife Society established an Urban Affairs and Regional Planning Committee in the mid-1970s that later became the Urban Wildlife Committee and then evolved into the Urban Wildlife Working Group. Urban wildlife research is providing knowledge of wildlife and plant populations and communities in urban areas that hopefully will lead to better understanding and greater sustainability of urban ecosystems.     

Urban ecosystems: the human dimension

This paper develops a human ecological perspective on cities and urban regions. It describes the role of cities in the expanding human ecological niche and its implications for sustainable urban development. I have used a new technique, ecological footprint analysis, to convert the material and energy flows required to sustain the human population and industrial metabolism of the city into a landecosystem area equivalent. This approach emphasizes that, although urbanization has become the dominant human settlement pattern, cities themselves constitute only a small part of the total ecological space appropriated by their human inhabitants. In short, the ecological locations of human settlements no longer coincide with their geographic locations. Every city and urban region depends for its existence and growth on a globally diffuse productive hinterland up to 200 times the size of the city itself. Cities are therefore increasingly vulnerable to global ecological change and geopolitical instability. Given the deteriorating state of the ecosphere, policies to decrease the ecological footprint of cities while increasing regional self-reliance may enhance urban sustainability.     

A conceptual framework for the study of human ecosystems in urban areas

The need for integrated concepts, capable of satisfying natural and social scientists and supporting integrated research, motivates a conceptual framework for understanding the role of humans in ecosystems. The question is how to add humans to the ecological models used to understand urban ecosystems. The ecosystem concept can serve as the basis, but specific social attributes of humans and their institutions must be added. Learning and feedback between the human and natural components of urban ecosystems are key attributes of the integrated model. Parallels with familiar ecological approaches can help in understanding the ecology of urban ecosystems. These include the role of spatial heterogeneity and organizational hierarchies in both the social and natural components of urban ecosystems. Although urban watersheds are commonly highly altered, the watershed approach can serve as a spatial basis for organizing comparative studies of ecosystems exhibiting differing degrees of urbanization. The watershed concept can also spatially organize the hierarchically scaled linkages by which the integrated human ecosystem model can be applied. The study of urban ecosystems is a relatively new field, and the questions suggested by the integrated framework can be used to frame ecosystem research in and associated with urban and metropolitan areas.     

How organizational characteristics affect the adaptive tactics used by human service nonprofit managers confronting financial uncertainty

The way that nonprofits respond to funding uncertainty is crucial to their ability to meet goals and position themselves for future success. This article investigates how structural, managerial, and financial characteristics affect the adaptive tactics used by human service nonprofits during times of financial stress. These tactics include adding new programs, reducing programs or staff, expanding or starting joint programs, pursuing earned income, and expanding advocacy involvement. Using longitudinal data on human service nonprofits collected on either side of the 2002–2003 economic downtown, we find that larger size provides organizations with a unique ability to choose among different adaptive tactics, as larger size was significantly predictive of adding new programs, reducing programs, expanding advocacy, and pursuing earned income. Strategic planning was positively associated with innovative tactics such as starting joint programs or pursuing earned income. Financial stress or declines in an organization's major funding source led to cutbacks, as expected, but managers who foresaw these challenges were able to respond proactively by adding programs or starting joint programs. However, managers with more training did not respond much differently than did other managers, and organizational age and use of performance management tools had no effect in guiding organizational responses to financial uncertainty.     

Interdisciplinary foundations of urban ecology

Researchers have identified urban ecology as a new field integrating social and ecological science. Critics have portrayed the field as under-theorized with negative implications for research and urban environmental planning. Unprecedented urbanization and historical bias against research integrating social and ecological systems are identified as driving this deficit. Researchers have called for new integrative approaches to address this issue. In response, this paper applies ecology’s analytic framework of “patch dynamics”, Kuhn’s concept of “normal science” and Mazoyer and Roudart’s “evolutionary series” to demographic data and historical texts to perform an analysis of interdisciplinary contributions to theory applicable in the field of urban ecology. The subsequent exploration reveals a rich history of interdisciplinary inquiry along the nature/society divide. The paper concludes that these “largely ignored” contributions offer urban ecology the opportunity to claim much broader depth as a field gaining access to precedents and innovations accomplished during the field’s early theoretical development. Drawing upon this history, a framework for ecological urban development is suggested to inform and assist contemporary research in urban ecology and planning.

Multidimensional Resilience: Predictive and Construct Validity of the Individual,Family, and Community Resilience Profile

Few measures parallel the robust depth offered in the existing multidimensional and ecologically informed theories of resilience. This study sought to evaluate the test–retest reliability, construct, and predictive validity of the individual, family, and community resilience resource profile (IFCR-R). The IFCR-R measures a family’s access to resilience resources and protective factors across multiple ecological levels. Confirmatory factor analysis was used with a sample of n?=?810 low-income families. And 159 families completed multiple time point measures for test–retest reliability and predictive validity evaluation. Results of this study support the proposed multidimensional ecological structure of the IFCR-R and found that the IFCR-R offers an acceptable test–retest reliability and predictive validity for outcomes of mental and physical health.     

Nesting ecology of mourning doves in an urban landscape

The expansion of urban areas into native habitat can have profound effects on avian populations and communities, yet little is known regarding the effects of urban features on avian reproductive success. The objective of this study was to examine the reproduction of an urban-enhanced species, the mourning dove, to determine how tree and urban landscape features affect nest-site selection and nest success. Mourning dove nests were located by systematically searching potential nest sites on a weekly basis from late-March through mid-September in 2003 and 2004. A total of 1,288 mourning dove nests were located and monitored on the Texas A&M University Campus. Of these nests, 337 (26.6%) were successful (fledged, ≥1). An equal number of potential nest sites were randomly generated in ArcGIS and assigned to non-nest trees to evaluate habitat variables associated with nest-site selection. Mourning dove nests were located in trees with a larger canopy diameter and diameter at breast height (DBH) than the computer generated potential nests and nest trees were located closer to roads and farther from buildings than non-nest trees. Within the study area, nest success was predominately influenced by the proximity of urban features with successful nests being located closer to roads and farther from buildings than unsuccessful nests.     

An ‘action‐poor’ human rights education: a critical review of the development of human rights education in the context of civic education in Hong Kong

In Hong Kong, human rights education (HRE) is considered an aspect of civic education. For decades, HRE has been poorly attended. In 2009, a new compulsory subject, Liberal Studies, where HRE can be infused, will be introduced to senior secondary students (15–18 years old). This article reviews the development of HRE within civic education, followed by the analysis of Liberal Studies documents with reference to international human rights documents. It is concluded that Liberal Studies can be used as a vehicle for HRE. The aims and pedagogy proposed are similar to those adopted by HRE. International standards of human rights can be incorporated in the content. However, the HRE derived from Liberal Studies is a form of ‘action‐poor HRE’. Whether this ‘action‐ poor HRE’ can adequately cultivate a universal human rights culture is an issue for further research.     

Resiliency in Divorced Families

Abstract

The aim of this cross-sectional and exploratory study was to identify resiliency factors that are associated with family adaptation after divorce. Questionnaires (The Family Hardiness Index, The Family Crisis Oriented Personal Evaluation Scales, The Relative and Friend Support Index, The Social Support Index, The Family Sense of Coherence Scale) and an open-ended question were used to collect data independently from parents and children belonging to 68 divorced families in Belgium. Results indicate that there is a significant positive correlation between the three components of family hardiness (commitment, challenge, and control—according to the parents) and the family's adaptation to its changed circumstances. There are also positive correlations for both parents and children between the positive redefining of stressful situations by the family, the social support of the family, and the family's adaptation after divorce. According to the children there are also significant positive relationships between the family's use of avoidance strategies, the parents' educational level, the number of years that the parent had been divorced, and the family's adaptation.     

Response to Young and Wolf: goal attainment in urban ecology research

Our critique focuses on the poorly defined key concepts, methodological inconsistencies, circular research design, and over-reaching substantive claims made by Young and Wolf. We suggest that Young and Wolf have provided an assessment of the Urban Ecosystems journal, not of urban ecology as a field. We conclude by identifying questions to guide a bibliometric analysis that focuses on a collaborative and interdisciplinary future of urban ecology (how are participating disciplines contributing to urban ecological research and scholarship; what theories and conceptual frameworks are being used, and how are these theories being tested and modified; and what mixed methodologies are being developed to collect data to address complex urban issues that are inherently interdisciplinary). We take seriously Young and Wolf’s call for a “fundamental discussion as to if and how the intentions of the field have been or need to be updated” and argue that such a discussion requires a more inclusive, rigorous, and meaningful identification of the “core” of urban ecology literature than provided.     

Toward a pragmatic program for critical urban ecology

Our essay responds to the critique of Dooling et al. (Urban Ecosystems in press, 2007) of our previously published article “Goal attainment in urban ecology research: a bibliometric review 1975-2004 (Young and Wolf, Urban Ecosystems, 9:179–193, 2006). We identify our critics’ concerns as rooted in a project of deconstruction of scientific inquiry and a redefinition of the boundaries separating academic disciplines from each other and science from society. While we identify important differences with our critics, we largely support this critical project, as evidenced by our previously published empirical research. In exploring the relationship between critical and positivist approaches to urban ecology research and how we might work toward an integration of nature and society in thought and action, we defend pragmatic approaches to empirical research as well as disciplinary projects as legitimate and essential elements of urban ecology research. We argue in favor of theoretical and methodological pluralism. Rather than define urban ecology through exclusionary projects that would limit the scope and significance of urban ecology research, we reaffirm our call for diverse sets of actors inside and outside university settings to engage and support each other in order to develop and strengthen analysis and pursuit of sustainability.

Urban soil ecology as a focal point for environmental education

Direct contact with the natural world is an essential element of environmental education and a key to developing environmental literacy and a stewardship ethic. But providing this experience can be challenging in urban environments where many people believe nature only occurs “outside” the city, and urban biota are often unwelcome and perceived in negative terms. Since 80% of the United States’ population lives in or near urban areas, conservation educators and practitioners need to find ways to make nature accessible to this audience, thereby creating a public who can make informed decisions about environmental issues. Soil systems are an important, under-utilized resource for urban environmental education. Soils are ubiquitous and thus easily accessible and their communities can be effective focal points for introducing all levels of ecology, from populations to ecosystems. Soil and litter taxa are also intrinsically interesting, with discoveries of new species still being made in urban areas. By studying urban soil systems, students can develop an enhanced sense of place and an appreciation of the natural world and their connection to it thereby strengthening environmental stewardship. An important role exists for urban ecologists to work with educators to impart enthusiasm for and to augment educators’ understanding of soil systems.

Habitat structure: A fundamental concept and framework for urban soil ecology

Habitat structure is defined as the composition and arrangement of physical matter at a location. Although habitat structure is the physical template underlying ecological patterns and processes, the concept is relatively unappreciated and underdeveloped in ecology. However, it provides a fundamental concept for urban ecology because human activities in urban ecosystems are often targeted toward management of habitat structure. In addition, the concept emphasizes the fine-scale, on-the-ground perspective needed in the study of urban soil ecology. To illustrate this, urban soil ecology research is summarized from the perspective of habitat structure effects. Among the key conclusions emerging from the literature review are: (1) habitat structure provides a unifying theme for multivariate research about urban soil ecology; (2) heterogeneous urban habitat structures influence soil ecological variables in different ways; (3) more research is needed to understand relationships among sociological variables, habitat structure patterns and urban soil ecology. To stimulate urban soil ecology research, a conceptual framework is presented to show the direct and indirect relationships among habitat structure and ecological variables. Because habitat structure serves as a physical link between sociocultural and ecological systems, it can be used as a focus for interdisciplinary and applied research (e.g., pest management) about the multiple, interactive effects of urbanization on the ecology of soils.

Notes from underground: fugitive ecology and the ethics of place

Abstract

In this essay, I argue for “fugitive gardening” as a form of “poaching” or “resignifying,” a radical appropriation of hegemonic spaces and practices that both deconstructs the logics of mastery and hygienic possessiveness that underpin colonial culture, and articulates what we might call a fugitive ecology: a dispossession of self in relation to the environment, a refusal to conceive of land, soil or planet in terms of property. Fugitive gardening sets itself in opposition to the prisons, camps and forts that index South African political history, restorying place, environment, and the self as grounds for community formation, dialogue and cooperation. Through readings of Coetzee’s Life & Times of Michael K and other examples of literary and material gardening, I show how such cultivation represents a gesture of belonging in a context where such claims are revolutionary, even treasonous; but unlike farm, fort or prison, fugitive gardening stakes a claim to belonging without possession, home without property and ecological care without an investment in the future. As such, gardening entails a very different understanding of self in relation to place, to nature and to future generations, and a reconceptualisation of narrative and language as representational modes.     

The Google voter: search engines and elections in the new media ecology

This paper explores key Internet search trends for electoral information vis-à-vis the broader media ecology in the UK and the US. An innovative methodology is introduced that maps the informational trajectories of key election events by combining Google Trends data linked to significant news events during the campaigns. While the research found spikes of search that suggested a seemingly trivial event in the US could drive voters to search out deeper information on related policy issues, the study did not find the same phenomenon in the UK. This invites a reflection on the opportunities available to Internet users/voters in the changing informational landscape and how scholars can leverage Google Trends records to better understand how voters seek information in new and evolving media ecologies.     

Place-based urban ecology: A century of park planning in Seattle

This research responds to calls from within the field of urban ecology to explicitly incorporate humanities-based research in order to achieve robust interdisciplinarity. Our research provides an example of a place-based urban ecological analysis. We use this framework to analyze over a century of park planning and development within the city of Seattle. We identify four eras of park planning that are linked by a comprehensive 100-year park plan. This case study examines how the political, cultural, and economic aspects of park planning have produced and been influenced by long-term trends and historical contingencies. This research also offers practical insights for effective contemporary urban planning, emphasizing the need for flexible and adaptive long-term plans when confronted with unpredictable events, emerging political arrangements, changing cultural priorities, and shifting fiscal climates.
