Quantifying Plant Population Persistence in Human-Dominated Landscapes

CONSERVATION BIOLOGY, Issue 4 2008
DAWN M. LAWSON
Base de Datos de la Diversidad Natural de California; conservación de plantas; crecimiento de la población; especies en peligro; paisajes urbanos Abstract:,We assessed population performance of rare plants across a gradient from rural to urban landscapes and evaluated 2 hypotheses central to strategic conservation planning: (1) population performance declines with increasing human dominance and (2) small populations perform poorly relative to larger ones. Assessing these hypotheses is critical to strategic conservation planning. The current conservation paradigm adheres to the well-established ecology theory that small isolated populations, particularly those in human-dominated landscapes, are the least likely to succeed over the long term. Consequently, conservation planning has strongly favored large, remote targets for protection. This shift in conservation toward ecosystem-based programs and protection of populations within large, remote systems has been at the expense of protection of the rarest of the rare species, the dominant paradigm for conservation driven by the endangered species act. Yet, avoiding conservation of small populations appears to be based more on theoretical understanding and expert opinion than empiricism. We used Natural Heritage data from California in an assessment of population performance of rare plants across a landscape with an urban-rural gradient. Population performance did not decrease in urban settings or for populations that were initially small. Our results are consistent with a pattern of few species extinctions within these landscapes over the past several decades. We conclude that these populations within compromised landscapes can contribute to overall biodiversity conservation. We further argue that conservation planning for biodiversity preservation should allocate relatively more resources to protecting urban-associated plant taxa because they may provide conservation benefit beyond simply protecting isolated populations; they may be useful in building social interest in conservation. Resumen:,Evaluamos el funcionamiento de la población de plantas raras a lo largo de un gradiente de paisajes rurales a urbanos y evaluamos 2 hipótesis centrales para la planificación estratégica de la conservación: (1) declinaciones en el funcionamiento poblacional con el incremento de la dominancia humana y (2) las poblaciones pequeñas funcionan pobremente en relación con las grandes. La evaluación de estas hipótesis es crítica para la planificación estratégica de la conservación. El paradigma actual de la conservación se adhiere a la teoría ecológica bien establecida que propone que las poblaciones pequeñas aisladas, particularmente en paisajes dominados por humanos, tienen menor probabilidad de sobrevivir a largo plazo. Consecuentemente, la planificación de la conservación ha favorecido objetivos grandes y remotos. Este cambio hacia programas de conservación basados en ecosistemas y la protección de poblaciones en sistemas extensos y remotos ha sido a costa de la protección de las especies más raras entre las raras, el paradigma dominante en la conservación conducida por el acta de especies en peligro. No obstante, la evasión de la conservación de poblaciones pequeñas parece estar basada más en entendimiento teórico y en la opinión de expertos que en el empirismo. Utilizamos datos del Patrimonio Natural de California en una evaluación del funcionamiento de plantas raras en un paisaje con un gradiente urbano a rural. El funcionamiento de la población no decreció en sitios urbanos o en poblaciones que eran pequeñas inicialmente. Nuestros resultados son consistentes con un patrón de extinción de especies en estos paisajes en las últimas décadas. Concluimos que estas poblaciones en paisajes comprometidos pueden contribuir a la conservación de la biodiversidad en general. También argumentamos que la planificación de la conservación para la preservación de la biodiversidad debería asignar más recursos para la protección de taxa de plantas asociadas a ambientes urbanos porque pueden proporcionar beneficios de conservación más allá de simplemente proteger poblaciones aisladas; pueden ser útiles para construir el interés social por la conservación.

Matching Response to Context in Complex Political Emergencies: ,Relief', ,Development', ,Peace-building' or Something In-between?

DISASTERS, Issue 4 2000
Philip White
There is an ongoing debate over the value and pitfalls of the policy and practice of ,linking relief and development' or ,developmental relief' in aid responses to complex political emergencies (CPEs). Driven by concerns about relief creating dependence, sometimes doing harm and failing to address root causes of emergencies despite its high cost, pursuit of both relief and development has become a dominant paradigm among international aid agencies in CPEs as in ,natural' disasters. In CPEs a third objective of ,peace-building' has emerged, along with the logic that development can itself help prevent or resolve conflict and sustain peace. However, this broadening of relief objectives in ongoing CPEs has recently been criticised on a number of counts, central concerns being that it leads to a dilution of commitment to core humanitarian principles and is overly optimistic. This paper addresses these issues in the light of two of the CPEs studied by the COPE project: Eritrea and Somalia/Somaliland. It is argued that the debate has so far suffered from lack of clarity about what we mean by ,relief', ,development' and, for that matter, ,rehabilitation' and ,peace-building'. The wide spectrum of possible aid outcomes does not divide neatly into these categories. The relief,development divide is not always as clear-cut, technically or politically, as the critics claim. Moreover such distinctions, constructed from the point of view of aid programmers, are often of little relevance to the concerns of intended beneficiaries. Second, there has been insufficient attention to context: rather than attempting to generalise within and across CPE cases, a more productive approach would be to examine more closely the conditions under which forms of aid other than basic life support can fruitfully be pursued. This leads to consideration of collective agency capacity to respond effectively to diverse needs in different and changing circumstances. [source]


River restoration, habitat heterogeneity and biodiversity: a failure of theory or practice?

FRESHWATER BIOLOGY, Issue 2010
MARGARET A. PALMER
Summary 1. Stream ecosystems are increasingly impacted by multiple stressors that lead to a loss of sensitive species and an overall reduction in diversity. A dominant paradigm in ecological restoration is that increasing habitat heterogeneity (HH) promotes restoration of biodiversity. This paradigm is reflected in stream restoration projects through the common practice of re-configuring channels to add meanders and adding physical structures such as boulders and artificial riffles to restore biodiversity by enhancing structural heterogeneity. 2. To evaluate the validity of this paradigm, we completed an extensive evaluation of published studies that have quantitatively examined the reach-scale response of invertebrate species richness to restoration actions that increased channel complexity/HH. We also evaluated studies that used manipulative or correlative approaches to test for a relationship between physical heterogeneity and invertebrate diversity in streams that were not in need of restoration. 3. We found habitat and macroinvertebrate data for 78 independent stream or river restoration projects described by 18 different author groups in which invertebrate taxa richness data in response to the restoration treatment were available. Most projects were successful in enhancing physical HH; however, only two showed statistically significant increases in biodiversity rendering them more similar to reference reaches or sites. 4. Studies manipulating structural complexity in otherwise healthy streams were generally small in scale and less than half showed a significant positive relationship with invertebrate diversity. Only one-third of the studies that attempted to correlate biodiversity to existing levels of in-stream heterogeneity found a positive relationship. 5. Across all the studies we evaluated, there is no evidence that HH was the primary factor controlling stream invertebrate diversity, particularly in a restoration context. The findings indicate that physical heterogeneity should not be the driving force in selecting restoration approaches for most degraded waterways. Evidence suggests that much more must be done to restore streams impacted by multiple stressors than simply re-configuring channels and enhancing structural complexity with meanders, boulders, wood, or other structures. 6. Thematic implications: as integrators of all activities on the land, streams are sensitive to a host of stressors including impacts from urbanisation, agriculture, deforestation, invasive species, flow regulation, water extractions and mining. The impacts of these individually or in combination typically lead to a decrease in biodiversity because of reduced water quality, biologically unsuitable flow regimes, dispersal barriers, altered inputs of organic matter or sunlight, degraded habitat, etc. Despite the complexity of these stressors, a large number of stream restoration projects focus primarily on physical channel characteristics. We show that this is not a wise investment if ecological recovery is the goal. Managers should critically diagnose the stressors impacting an impaired stream and invest resources first in repairing those problems most likely to limit restoration. [source]


Signals of Reconciliation: Institution-Building and the Resolution of Civil Wars

INTERNATIONAL STUDIES REVIEW, Issue 1 2005
Matthew Hoddie
Recent studies of civil war have tended to apply concepts associated with neorealist analyses of international conflict to understand the dynamics of disputes among collectivities within a state. The intention of the present essay is to demonstrate that this reliance on neorealist theory has resulted in the neglect of viable solutions to these conflicts that are inconsistent with the dominant paradigm. We suggest that an alternative international relations perspective, neoliberal institutionalism, can also serve as a prescription for post-civil war stability. Consistent with this perspective, we identify a process in which negotiating and establishing power-sharing institutions serves two important functions in the resolution of civil wars. First, the institutions created through this process serve as the basis for establishing a new political order. Second, the act of developing postwar institutions provides a means by which former adversaries can generate the often costly signals of conciliatory intent necessary for fostering new norms of peaceful cooperation. We demonstrate the value of this framework through a case study of conflict resolution in the Philippines. [source]


The voice of historical biogeography

JOURNAL OF BIOGEOGRAPHY, Issue 2 2001
Jorge V. Crisci
Historical biogeography is going through an extraordinary revolution concerning its foundations, basic concepts, methods, and relationships to other disciplines of comparative biology. There are external and internal forces that are shaping the present of historical biogeography. The external forces are: global tectonics as the dominant paradigm in geosciences, cladistics as the basic language of comparative biology and the biologist's perception of biogeography. The internal forces are: the proliferation of competing articulations, recourse to philosophy and the debate over fundamentals. The importance of the geographical dimension of life's diversity to any understanding of the history of life on earth is emphasized. Three different kinds of processes that modify the geographical spatial arrangement of the organisms are identified: extinction, dispersal and vicariance. Reconstructing past biogeographic events can be done from three different perspectives: (1) the distribution of individual groups (taxon biogeography) (2) areas of endemism (area biogeography), and (3) biotas (spatial homology). There are at least nine basic historical biogeographic approaches: centre of origin and dispersal, panbiogeography, phylogenetic biogeography, cladistic biogeography, phylogeography, parsimony analysis of endemicity, event-based methods, ancestral areas, and experimental biogeography. These nine approaches contain at least 30 techniques (23 of them have been proposed in the last 14 years). The whole practice and philosophy of biogeography depend upon the development of a coherent and comprehensive conceptual framework for handling the distribution of organisms and events in space.

Defining sustainability: a conceptual orientation

JOURNAL OF CHEMICAL TECHNOLOGY & BIOTECHNOLOGY, Issue 4 2007
Robert O. Vos
Abstract Despite the ubiquity of the concept of sustainability, defining the term and construing meaning for different contexts is difficult. This paper presents several archetypes of sustainability that are useful for classifying and understanding existing definitions. Definitions that emphasize one part or another of the core concept of sustainability will be necessary at varying scales and in different contexts. This paper presents a conceptual guide that contrasts a dominant paradigm of economic growth and development with ,thick' and ,thin' versions of sustainability. Definitions of sustainability are explored in terms of their orientation to the ontology of nature, substitutability of resources, economic growth, population growth, role of technology, and social equity.

Urban Regime Theory: A Normative-Empirical Critique

JOURNAL OF URBAN AFFAIRS, Issue 1 2002
Jonathan S. Davies
Over the past 10 years, urban regime theory has become the dominant paradigm for studying urban politics in liberal democracies. Yet there is disagreement about how far it can help us to understand urban political processes. This article argues that regime theory is best understood as a theory of structuring with limits in its analysis of the market economy. These limits undermine its ability to explain the importance of political agency,the scope of individual or collective choice in political decisions and the impact of those choices in the evolution of US cities. It is further argued that there are important normative dimensions to urban regime theory, most fully articulated in Elkin's commercial republic, which academic commentaries have not acknowledged. However, the empirical analysis developed in regime theory contradicts its normative objectives. The absence of a conceptualization of market dynamics, in the light of pessimism about the prospects for equitable regime governance, not only limits it as a theory of structuring but it also renders it unable to explain how the commercial republic can be realized. Regime theory is, therefore, unconvincing for two reasons. It cannot explain how much local politics matter, and it fails to demonstrate that its normative goal,more equitable regime governance,can be achieved, given the realities of the US market economy. Regime theory needs a more developed understanding of structuring. It may be fruitful, therefore, for regime theorists to re-engage critically with variants of Marxism, which unlike Structuralism, recognize the possibility of agency. [source]


The deconstructing angel: nursing, reflection and evidence-based practice

NURSING INQUIRY, Issue 2 2005
Gary Rolfe
The deconstructing angel: nursing, reflection and evidence-based practice This paper explores Jacques Derrida's strategy of deconstruction as a way of understanding and critiquing nursing theory and practice. Deconstruction has its origins in philosophy, but I argue that it is useful and relevant as a way of challenging the dominant paradigm of any discipline, including nursing. Because deconstruction is notoriously difficult to define, I offer a number of examples of deconstruction in action. In particular, I focus on three critiques of reflective practice by the meta-narrative of evidence-based practice (EBP) and attempt to show how those critiques can be directed back at EBP itself. I conclude with the observation that EBP is open to many of the criticisms that it directs at other discourses, including problems of a lack of empirical evidence, of distortions due to memory, and of falsification of the ,facts'.

"New Governance" and Associative Pluralism: The Case of Drug Policy in Swiss Cities

POLICY STUDIES JOURNAL, Issue 4 2003
Sonja Wälti
Throughout the 1990s, hierarchical administrative governance structures have been replaced by self-governing networks for various motives, one of which is to improve the authenticity and democratic quality of public decisions. Thus, "new governance" has been praised for its propensity to provide a plurality of civil society organizations with access to the decision process. This article explores these claims based on the case of drug policy in Swiss cities. We show that self-governing networks indeed seem to have increased the involvement of civil society organizations in the policy process. However, we also find evidence that self-governing networks may in the longer run induce state control over civil society organizations, thus ultimately reducing associative pluralism. They do so either by imposing a policy paradigm or by excluding actors who do not comply with the dominant paradigm from the networks. We conclude by arguing that self-organizing networks should not be dismissed, given that former hierarchical bureaucratic approaches to drug-related problems have failed even worse. Rather, their long-term effects should be subject to further examination aimed at developing adequate responses to their shortcomings. [source]


Abandoned Women and Spaces of the Exception

ANTIPODE, Issue 5 2005
Geraldine Pratt
I consider two cases of legal abandonment in Vancouver,of murdered sex workers and live-in caregivers on temporary work visas,in light of Agamben's claim that the generalized suspension of the law has become a dominant paradigm of government. I bring to Agamben's theory a concern to specify both the gendering and racialisation of these processes, and the many geographies that are integral to legal abandonment and the reduction of categories of people to ,bare life'. The case studies also allow me to explore two limit-concepts that Agamben offers as a means to re-envision political community: the refugee who refuses assimilation in the nation-state, and the human so degraded as to exist beyond conventional humanist ethics of respect, dignity and responsibility.

GENDER AND ETHICS COMMITTEES: WHERE'S THE ,DIFFERENT VOICE'?

BIOETHICS, Issue 3 2006
DONNA DICKENSON
ABSTRACT Prominent international and national ethics commissions such as the UNESCO International Bioethics Committee rarely achieve anything remotely resembling gender equality, although local research and clinical ethics committees are somewhat more egalitarian. Under-representation of women is particularly troubling when the subject matter of modern bioethics so disproportionately concerns women's bodies, and when such committees claim to derive ,universal' standards. Are women missing from many ethics committees because of relatively straightforward, if discriminatory, demographic factors? Or are the methods of analysis and styles of ethics to which these bodies are committed somehow ,anti-female'? It has been argued, for example, that there is a ,different voice' in ethical reasoning, not confined to women but more representative of female experience. Similarly, some feminist writers, such as Evelyn Fox Keller and Donna Haraway, have asked difficult epistemological questions about the dominant ,masculine paradigm' in science. Perhaps the dominant paradigm in ethics committee deliberation is similarly gendered? This article provides a preliminary survey of women's representation on ethics committees in eastern and western Europe, a critical analysis of the supposed ,masculinism' of the principlist approach, and a case example in which a ,different voice' did indeed make a difference.

Evolution of strategic management: The need for new dominant designs

INTERNATIONAL JOURNAL OF MANAGEMENT REVIEWS, Issue 2 2005
Pol Herrmann
The development of strategic management is explained from an evolutionary perspective on the basis of cycles of variation, selection and retention. In industry, breakthrough innovations, or technological discontinuities, initiate eras of ferment that end when a generally accepted standard, or dominant design, starts an era of incremental change. In strategic management, the original definition of strategy initiated an era of ferment characterized by a focus on the environment. The attention to the environment of firms and the integration with other areas of inquiry reached a point of maturity with development of a widely accepted model for analyzing industry and with the definition of generic strategies. The resource-based view of the firm created a new era of ferment by affirming that the main sources of sustainable competitive advantages reside in the development and use of valuable resources. A new period, marked by swift advances in technology and increasingly blurred boundaries among industries, markets and competitors as well as diverse and more complex sources of competitive advantages, imposes on scholars and practitioners an imperative need to conceive new dominant designs. This paper illustrates the evolution toward new directions and challenges of creating new dominant paradigms in strategic management that revolve around the concepts of knowledge, learning, and innovation.

Inequality and Theorizing in International Relations: The Case for Subaltern Realism

INTERNATIONAL STUDIES REVIEW, Issue 3 2002
Mohammed Ayoob
I argue that the dominant paradigms in IR fail to explain adequately two of the central issues in the international system: the origins of the majority of conflicts and the behavior of the majority of states. These paradigms fail because they formulate generalizations from data drawn from a restricted universe and because they lack historical depth. Both these flaws are related to inequality in the arena of the production of knowledge in IR, which in turn is a function of the inequality in material capabilities in the international system. A supplementary, if not alternative, perspective is needed to correct this situation and fill this gap. We can fashion such a perspective by drawing upon classical realist thought, the historical sociology of state formation, and the normative perspicacity of the English School. Combining their insights and applying them to the analysis of Third World conflict patterns and the external and domestic behavior of Third World states is likely to provide more satisfactory explanations for the origins of the majority of contemporary conflicts. Such an exercise will also shed light on the crucial variables that determine the behavior of the majority of states in the Third World. Moving postcolonial states into the mainstream of theorizing in IR will also help reduce the impact of inequality on the field and open new vistas for theoretically informed scholarly research. I also call for pluralism in international relations theorizing rather than a search for universally applicable law,like generalizations divorced from historical and social contexts. [source]


A new vision for the field: Introduction to the second special issue on the unified theory

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 1 2005
Gregg R. Henriques
This is the second of two issues of the Journal of Clinical Psychology focused on the validity and usefulness of a new theoretical vision for the field (Henriques, 2003). The first two contributions from Rand and Ilardi and Geary both enrich the argument that psychology needs to be effectively connected with biology and physics and that the unified theory (via Behavioral Investment Theory) is highly successful in this way. The authors of the subsequent three articles,Shaffer, Quackenbush, and Shealy,show that the Tree of Knowledge System (through the Justification Hypothesis) is deeply commensurate with the dominant paradigms in the social sciences. Thus, the group of authors of these five articles demonstrates the viability of the unified theory both from bottom-up and top-down viewpoints. In the sixth article, the author addresses some important problems that potentially arise with the development of a clearly defined discipline. In the concluding article I address the concerns about the proposal raised by the contributors to the two special issues and articulate how the unified theory lays the foundation for the development of a useful mass movement in psychology. © 2004 Wiley Periodicals, Inc.

Merton as Harvard sociologist: Engagement, thematic continuities, and institutional linkages

JOURNAL OF THE HISTORY OF THE BEHAVIORAL SCIENCES, Issue 1 2010
Lawrence T. Nichols
In this paper I explore the significance of the initial decade of Robert K. Merton's graduate and professional career, from 1931, when he entered the new doctoral program in sociology at Harvard, until 1939, when he joined the Department of Sociology at Tulane University as an associate professor and acting chairperson. Drawing on archival sources, as well as the professional literature, I examine how Merton engaged the exceptionally rich, interdisciplinary context of Harvard in the 1930s, including both interpersonal networks and diverse intellectual perspectives. In particular, I identify connections between Merton's early writing, "oral publications" and teaching, and three locally developed and dominant paradigms of sociology. Following an assessment of the influence of Merton's works published from 1934 to 1939, I trace continuities between Merton's achievements at Harvard and his subsequent teaching and research at Tulane and Columbia. I conclude that a fuller appreciation of Merton's "less noticed" decade in Cambridge is indispensable for understanding his overall career, and that it clarifies linkages across sociological work at three universities in the mid-twentieth century. © 2010 Wiley Periodicals, Inc.
