Relations of fish community composition to environmental variables in streams of central Nebraska,USA

Nine sites on streams in the Platte River Basin in central Nebraska were sampled as part of the US Geological Survey's National Water-Quality Assessment Program during 1993–1994. A combination of canonical correspondence analysis and an index of biotic integrity determined from fish community data produced complementary evaluations of water-quality conditions. Results of the canonical correspondence analysis were useful in showing which environmental variables were significant in differentiating fish communities at the nine sites. Five environmental variables were statistically significant in the analysis. Median specific conductance of water samples collected at a site accounted for the largest amount of variability in the species data. Although the percentage of the basin as cropland was not the first variable chosen in a forward selection process, it was the most strongly correlated with the first ordination axis. A rangeland-dominated site was distinguished from all others along that axis. Median orthophosphate concentration of samples collected in the year up to the time of fish sampling was most strongly correlated with the second ordination axis. The index of biotic integrity produced results that could be interpreted in terms of the relative water quality between sites. Sites draining nearly 100% cropland had the lowest scores for two individual metrics of the index of biotic integrity that were related to species tolerance. Effective monitoring of water quality could be achieved by coupling methods that address both the ecological components of fish communities and their statistical relationships to environmental factors.     

可燃性气体含氧量安全限值的探讨

Whose voices count in biodiversity conservation? Ecological democracy in biodiversity offsetting,REDD+, and rewilding

ABSTRACT

Ecological democracy seeks environmentally sustainable ends through broad, active democratic participation. What happens when laws fostering participation in environmental decision-making and biodiversity preservation lead to differing results? What is best for biodiversity may not be what for local citizens believe is best. I examine conflicts and congruencies in the context of Biodiversity Offsetting, REDD+ (Reducing Emissions from Deforestation and forest Degradation), and the Rewilding movement. I ask questions that are legal (Who has what legal rights to speak for or against programs that enhance biodiversity?), epistemological (Whose expertise and knowledge matters when scientists and non-scientists don't agree?), axiological (Are some values objectively better, and why?), and normative (Whose opinions about biodiversity should count?). Many people have the right to participate in an ecological democracy: But when protecting biodiversity, who does and should have the right to be heard? I problematize the role that ‘local’ actors play in decision-making and describe the variegated role that experts – particularly biologists – play in ecological democracy when biodiversity preservation matters. To determine whose values and voices should be prioritized, I describe ‘deep equity,’ an axiological and normative groundwork for determining when biodiversity-promoting policies may be preferable even if affected citizens don't agree.     

Between environmental and ecological democracy: theory and practice at the democracy-environment nexus

ABSTRACT

Concepts of ecological and environmental democracy seek to reconcile two normative ideals: ensuring environmental sustainability while safeguarding democracy. These ideals are frequently conceived as being in conflict, as democracy is perceived as too slow and cumbersome to deliver the urgent large-scale collective action needed to tackle environmental problems. Theories addressing the democracy-environment nexus can be situated on a spectrum from theories of ecological democracy that are more critical of existing liberal democratic institutions to theories of environmental democracy that call for reforming rather than radically transforming or dismantling those institutions. This article reviews theoretical and empirical scholarship on the democracy-environment nexus. We find continued theoretical and empirical diversity in the field, as well as vibrant debates on democratising global environmental politics, local material practices, and non-human representation. We argue for stronger dialogue between environmental political theory and empirical, policy-oriented research on democracy and sustainability, as well as further exploration of complementarities between ecological and environmental democracy. We identify four main areas of challenge and opportunity for theory and practice: public participation and populism; technocracy and expertise; governance across scales; and ecological rights and limits.
