Linking the landscape: legal and policy tools to promote connected habitats in fragmented landscapes
No full textWe have entered a sixth mass extinction period, and habitat loss due to human land uses has been named as one of its leading causes. By converting land to urban and agricultural land uses, humans have fragmented millions of acres of once-contiguous habitat. Fragmentation alters the spatial configuration and ecological processes of the remnant habitat fragments. These ecological changes impact plant and animal species, leading to population declines and, for some, local or total extinction. The impacts of fragmentation are projected to become more pronounced as the climate changes, hindering many species from adapting to novel climate conditions by shifting to a range with more hospitable climate conditions. Corridors can improve species viability in heavily-fragmented landscapes as well as in a changing climate by facilitating movement between separate habitat patches. Establishing broad linkages is logically feasible in areas with large reserves of habitat, primarily in the north-western region of the United States. The rest of the nation, however, lacks large habitat reserves and is dominated by private landownership. How do we establish corridors in landscapes like those in central Illinois or the sprawling metro-Chicago suburbs? Implementing linkages in these landscapes will require a coordinated, inter-governmental effort on landscape and regional scales. Legally, we must integrate stewardship into private landowner duties, update the common law meaning of “harm” to encompass ecological harm, and enhance government ability to curb harmful land uses. To achieve real conservation gains, however, we must move socially and culturally toward an ethic of stewardship within the private landscape.Item withdrawn by Mark Zulauf ([email protected]) on 2010-04-29T19:38:26Z

Rivers, ecological health, and justice: international watercourses and long-term legal reform
Get PDFThis dissertation deals with rivers that cross national boundaries and with the international law that applies to them. It takes a critical look at that law, drawing upon normative standards that value justice among all people, without regard for where they live along rivers or for the negotiating strength of their home States, and that also value the long-term ecological health of rivers as aquatic systems. The dissertation pays particular attention to the most vulnerable States of the world on watercourse-related issues; to States that are located downstream, that have relatively weak negotiating powers in comparison with their upstream neighbors, and that face critical development needs. Bangladesh is used as the paradigm example. The dissertation draws upon current law and recent legal experiences to formulate a new vision for the international law of watercourses, a vision that, if implemented, would recognize and protect rivers as complex ecological wholes while promoting social justice among all people dependent on such rivers. In doing so, it puts forth an ambitious vision for long-term cultural as well as legal reform. The vision is offered less as a proposal for current consideration than as a way of clarifying deficiencies in current law and gaining a better sense of the overall direction in which more modest law reforms should head.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-05-01The student, Romin Tamanna, accepted the attached license on 2017-04-20 at 22:23.The student, Romin Tamanna, submitted this Dissertation for approval on 2017-04-20 at 22:46.This Dissertation was approved for publication on 2017-04-21 at 14:59.DSpace SAF Submission Ingestion Package generated from Vireo submission #10953 on 2017-08-10 at 15:06:40Made available in DSpace on 2017-08-10T20:33:18Z (GMT).

No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
