Environmental quality and aquaculture systems: Proceedings of the Thirteenth U.S.-Japan Meeting on Aquaculture, Mie, Japan, October 24-25, 1984

The United States and Japanese counterpart panels on aquaculture were formed in 1969 under the United States-Japan Cooperative Program in Natural Resources (UJNR). The panels currently include specialists drawn from the federal departments most concerned with aquaculture. Charged with exploring and developing bilateral cooperation, the panels have focused their efforts on exchanging information related to aquaculture which could be of benefit to both countries. The UJNR was begun during the Third Cabinet-Level Meeting of the Joint United States-Japan Committee on Trade and Economic Affairs in January 1964. In addition to aquaculture, current subjects in the program include desalination of seawater, toxic microorganisms, air population, energy, forage crops, national park management, mycoplasmosis, wind and seismic effects, protein resources, forestry, and several joint panels and committees in marine resources research, development, and utilization. Accomplishments include: Increased communication and cooperation among tecbnical specialists; exchanges of information, data, and research findings; annual meetings of the panels, a· policy-coordinative body; administrative staff meetings; exchanges of equipment, materials, and samples; several major technical conferences; and beneficial effects on international relations.

Soviet-American Cooperative Research on Marine Mammals. Volume 1- Pinnipeds: Under Project V.6. Marine Mammals, of the US-USSR Agreement on Cooperation in the Field of Environmental Protection

Some 25 to 30 yr ago, when we as students were beginning our respective careers and were developing for the first time our awareness of marine mammals in the waters separating western North America from eastern Asia, we had visions of eventually bridging the communication gap which existed between our two countries at that time. Each of us was anxious to obtain information on the distribution, biology, and ecological relations of "our" seals and walruses on "the other side," beyond our respective political boundari~s where we were not permitted to go to study them. We were concerned that the resource management practices on the other side of the Bering and Chukchi Seas, implemented in isolation, on a purely unilateral basis, might endanger the species which we had come to know and were striving to conserve. At once apparent to both of us was the need for free exchange of biological information between our two countries and, ultimately, joint management of our shared resources. In a small way, we and others made some initial efforts to generate that exchange by personal correspondence and through vocal interchange at the annual meetings of the North Pacific Fur Seal Commission. By the enabling Agreement on Cooperation in the Field of Environmental Protection, reached between our two countries in 1972, our earlier visions at last came true. Since that time, within the framework of the Marine Mammal Project under Area V of that Agreement, we and our colleagues have forged a strong bond of professional accord and respect, in an atmosphere of free intercommunication and mutual understanding. The strength and utility of this arrangement from the beginning of our joint research are reflected in the reports contained in this, the first compendium of our work. The need for a series of such a compendia became apparent to us in 1976, and its implementation was agreed on by the regular meeting of the Project in La Jolla, Calif., in January 1977. Obviously, the preparation and publication of this first volume has been excessively delayed, in part by continuing political distrust between our governments but mainly by increasing demands placed on the time of the contributors. In this period of growing environmental concern in both countries, we and our colleagues have been totally immersed in other tasks and have experienced great difficulty in drawing together the works presented here. Much of the support for doing so was provided by the State of Alaska, through funding for Organized Research at the University of Alaska-Fairbanks. For its ultimate completion in publishable form we wish to thank Helen Stockholm, Director of Publications, Institute of Marine Science, University of Alaska, and her staff, especially Ruth Hand, and the numerous referees narned herein who gave willingly oftheir time to review each ofthe manuscripts critically and to provide a high measure of professionalism to the final product.

Environmental monitoring review group feedback

The Drought Monitoring workshop of October 1996, held at the Jarvis Leyland Hotel in Preston, England, established 4 priority issues for dealing with the question: How do we monitor the environment to pick up unexpected change ? 1. Review existing data, and review related study areas throughout the country. 2. Modelling and analysis of data 3. Monitoring / new data / sentinel species' 4. Public relations / Promotion. A group was set up to review issue 1 and feedback to the main group. This report establishes this feedback to the group and refers to existing data / monitoring, other Regional and national work, external Organisations and Recommendations. Appendix 1, is a summary of work completed at the workshop.

A 139-year dendroclimatic cycle, cultural/environmental history, sunspots, and longer-term cycles

Higher resolution time-stratigraphic records suggest correlation of lower frequency paleoclimatic events with Milankovitch obliquity/precessional cycles and of higher frequency events with the evidently resonance-related Pettersson maximum tidal force (MTF) model. Subsequently published records, mainly pollen, seemingly confirm that atmospheric resonances may have modulated past climatic changes in phase with average MTF cycles of 1668, 1112, and 556 years, as calculated in anomalistic years from planetary movements by Stacey. Stacey accepts Pettersson's dating of AD 1433 (517 YBP) for the last major perihelian spring tide based solely on calculations of moon- and earth-orbital relations to the sun. Use of AD 1433 as an origin for the tidal resonance model seemingly continues to provide a best fit for the timing of cyclical patterns in the presented paleoclimate time series.

Grey relational analysis on the relation between marine environmental factors and oxidation-reduction potential

The effects of marine environmental factors-temperature (T), dissolved oxygen (DO), salinity (S) and pH-on the oxidation-reduction potential (ORP) of natural seawater were studied in laboratory. The results show an indistinct relationship between these four factors and the ORP, but they did impact the ORP Common mathematical methods were not applicable for describing the relationship. Therefore, a grey relational analysis (GRA) method was developed. The degrees of correlation were calculated according to GRA and the values of T, pH, DO and S were 0.744, 0.710, 0.692 and 0.690, respectively. From these values, the relations of these factors to the ORP could be described and evaluated, and those of T and pH were relatively major. In general, ORP is influenced by the synergic effect of T, DO, pH and S, with no single factor having an outstanding role.

Towards enhanced divine-human-earth relations: a Christian-Buddhist contribution

The central claim of the dissertation is that lesser known and somewhat neglected, yet influential thinkers, within classical religious traditions have something worthwhile to contribute to the kind of ethos we should adopt in the face of the world’s various environmental crises. Moreover an exploration of such perspectives is best done in dialogue, particularly between Eastern and Western thought. I examine this claim primarily through a dialogue between the Christian philosopher John Scottus Eriugena and the Japanese Buddhist philosopher Kūkai (Kōbō Daishi). This dialogue, framed by the triad of divine-human-earth relations, primarily emphasises the oneness of all reality, and it finds expression in Eriugena’s concept of natura or phusis and Kūkai’s central teaching that the phenomenal world is the cosmic Buddha Dainichi. By highlighting this focus, I contribute to the existing academic field of ecology and religion on the subject of holism. However, I go beyond the materialist focus that generally marks such ecological holism within that field, offering instead a more metaphysical approach. This is indicated through my use of the concept of ‘immanental transcendence’ to describe Eriugena’s and Kūkai’s dynamic, numinous and mysterious notion of reality, as well as my exploration of Eriugena’s concept of theophany and Kūkai’s notion of kaji. I further explore how both philosophers highlight the human role in the process of reaching enlightenment—understood as attaining union with the whole. In that regard, I note significant differences in their positions: in particular, I note that Kūkai’s emphasis on bodily practices contrasts with Eriugena’s more conceptual approach. Finally to bolster my claim, I examine some ecologically oriented understandings of contemporary phenomenological approaches found particularly in the work of Jean-Luc Marion and to a lesser extent Merleau-Ponty, arguing that these reflect notions of reality and of the human role similar to those of the medieval philosophers.

Cross-Border Environmental Governance and EC Law

This article examines the nature and scope of emerging cross-border participatory rights under European Community environmental law. It reviews the legal and political forces that have stimulated the development of such rights and also the specific nature of the rights conferred by three major legislative initiatives: the Community Directives on Environmental Impact Assessment, Integrated Pollution Prevention and Control, and the Water Framework Directive. The article concludes with a case study on Ireland which assesses the likely significance of these cross-border participatory rights for transboundary environmental governance in Ireland.

Part-whole relations between food webs and the validity of local food-web descriptions

This work analyzes the relationship between large food webs describing potential feeding relations between species and smaller sub-webs thereof describing relations actually realized in local communities of various sizes. Special attention is given to the relationships between patterns of phylogenetic correlations encountered in large webs and sub-webs. Based on the current theory of food-web topology as implemented in the matching model, it is shown that food webs are scale invariant in the following sense: given a large web described by the model, a smaller, randomly sampled sub-web thereof is described by the model as well. A stochastic analysis of model steady states reveals that such a change in scale goes along with a re-normalization of model parameters. Explicit formulae for the renormalized parameters are derived. Thus, the topology of food webs at all scales follows the same patterns, and these can be revealed by data and models referring to the local scale alone. As a by-product of the theory, a fast algorithm is derived which yields sample food webs from the exact steady state of the matching model for a high-dimensional trophic niche space in finite time.

Water and temperature relations of soil Actinobacteria

Actinobacteria perform essential functions within soils, and are dependent on available water to do so. We determined the water-activity (a_w) limits for cell division of Streptomyces albidoflavus, Streptomyces rectiviolaceus, Micromonospora grisea and Micromonospora (JCM 3050) over a range of temperatures, using culture media supplemented with a biologically permissive solute (glycerol). Each species grew optimally at 0.998 a_w (control; no added glycerol) and growth rates were near-optimal in the range 0.971–0.974 (1 M glycerol) at permissive temperatures. Each was capable of cell division at 0.916–0.924 a_w (2 M glycerol), but only S. albidoflavus grew at 0.895 or 0.897 a_w (3 M glycerol, at 30 and 37°C respectively). For S. albidoflavus, however, no growth occurred on media at ≤ 0.870 (4 M glycerol) during the 40-day assessment period, regardless of temperature, and a theoretical limit of 0.877 a_w was derived by extrapolation of growth curves. This level of solute tolerance is high for non-halophilic bacteria, but is consistent with reported limits for the growth and metabolic activities of soil microbes. The limit, within the range 0.895–0.870 a_w, is very much inferior to those for obligately halophilic bacteria and extremely halophilic or xerophilic fungi, and is inconsistent with earlier reports of cell division at 0.500 a_w. These findings are discussed in relation to planetary protection policy for space exploration and the microbiology of arid soils.

Water and Temperature Relations of Growth of the Entomogenous Fungi Beauveria bassiana, Metarhizium anisopliae, and Paecilomyces farinosus

The effects of temperature (5-50°C), water availability (0.998-0.88 water activity, aw), and aw × temperature interactions (15-45°C) on growth of three entomogenous fungi, Beauveria bassiana, Metarhizium anisopliae, and Paecilomyces farinosus, were evaluated on a Sabouraud dextrose-based medium modified with the ionic solute KCl, the non-ionic solute glycerol, and an inert solute, polyethylene glycol (PEG) 600. The temperature ranges for growth of B. bassiana, M. anisopliae, and P. farinosus were 5-30, 5-40, and 5-30°C, and optimum growth temperatures were 25, 30, and 20°C, respectively. All three species grew over a similar aw range (0.90-0.998) at optimum temperatures for growth. However, there were significant interspecies variations in growth rates on media modified with each of the three aw-modifying solutes. Growth aw optima ranged between 0.99 and 0.97 on KCl-, glycerol-, and PEG 600-modified media for M. anisopliae and P. farinosus. B. bassiana grew optimally at 0.998 aw, regardless of aw. Comprehensive two-dimensional profiles of aw × temperature relations for growth of these three species were constructed for the first time. The results are discussed in relation to the environmental limits that determine efficacy of entomogenous fungi as biocontrol agents in nature. © 1999 Academic Press.

Federal-provincial relations and the environment : attaining sustainable development through cooperation /

A study of intergovernmental relations in the area of the environment will determine whether the current Canadian federal structure represents a dangerous impediment to the promotion of sustainable development. This paper examines the interjurisdictional quagmire that has developed from the fact that authority over the environment is a functionally concurrent field for the two orders of government. A history of federal-provincial relations in the area of environmental protection is followed by an analysis of the advantages and disadvantages associated with competitive and cooperative federalism. For the purpose of this paper, cooperative federalism is characterized by the presence of a formal institutional system to facilitate interaction between politicians and bureaucrats from both orders of government. Competitive federalism is defined as a system that lacks a formal institutional structure to promote discussion and coordination between federal and provincial officials in a specific field of interest. Last, I examine thirty sustainable development issues following the structure established in Agenda 21 to determine the impact of the present federal system on the development of these objectives. This study concludes that Canadian federalism is not a dangerous impediment to the promotion of sustainable development. Cooperative federalism in a form that does not eliminate the ability of governments to revert to competition promotes the emergence of an institutional system that facilitates information-sharing and discussion between the two orders of government, thus leading to coordinated efforts in the field of the environment. Respect for the current division of powers in this area is also essential to the cohesiveness of Canadian society. Policy-makers and advocates for a sustainable society should focus on working within the present system.

Environmental Risk: Should Banks Be Liable?

This paper studies the impact of banks' liability for environmental damages caused by their borrowers. Laws or court decisions that declare banks liable for environmental damages have two objectives : (1) finding someone to pay for the damages and (2) exerting a pressure on a firm's stakeholders to incite them to invest in environmental risk prevention. We study the effect that such legal decisions can have on financing relationships and especially on the incentives to reduce environmental risk in an environment where banks cannot commit to refinance the firm in all circumstances. Following an environmental accident, liable banks more readily agree to refinance the firm. We then show that bank liability effectively makes refinancing more attractive to banks, therefore improving the firm's risk-sharing possibilities. Consequently, the firm's incentives to invest in environmental risk reduction are weakened compared to the (bank) no-liability case. We also show that, when banks are liable, the firm invests at the full-commitment optimal level of risk reduction investment. If there are some externalities such that some damages cannot be accounted for, the socially efficient level of investment is greater than the privately optimal one. in that case, making banks non-liable can be socially desirable.
