Large Predators

The ecological role of large predators in North America continues to spark heated public debate. Although brown bears (Ursus arctos L., 1758) and the salmon (genus Oncorhynchus Suckley, 1861) they feed on have declined in many areas, the Kodiak archipelago is famous for large brown bears and abundant salmon. Salmon have generally been managed for maximum sustained yield in a fisheries sense, but those levels may be well below what is necessary for maximum ecosystem productivity. Consequently, we used stable isotopes and mercury accumulated in hair to estimate intake of salmon by Kodiak brown bears (Ursus arctos middendorffi Merriam, 1896). Salmon intake increased from subadult males (592 ± 325 kg·bear−1·year−1) to adult males (2788 ± 1929 kg·bear−1·year−1) and from subadult females (566 ± 360 kg·bear−1·year−1) to adult females (1364 ± 1261 kg·bear−1·year−1). Intake within each group increased 62% ± 23% as salmon escapement increased from ∼1 500 to ∼14 000 kg·bear−1·year−1. The estimated population of 2300 subadult and adult bears consumed 3.77 ± 0.16 million kg of salmon annually, a mass equal to ∼6% of the combined escapement and commercial harvest (57.6 million kg). Although bears consume a small portion of the total mass of adult salmon, perpetuation of dense populations of large bears requires ecosystem-based management of the meat resources and environments that produce such bears.

Landscape Quality

Since the Millennium Ecosystem Assessment Project proposed the valuation of ecosystem services—defined as regulatory, provisional, ecosystem and cultural—the question arises as to the utility of such assessments for scenic landscape management. This author as well as others has looked at the issue of integrating ecological concerns with landscape planning. This article will be a comprehensive literature review and analysis of issues involved with utilizing ecosystem services of assessment of scenic/visual landscape quality as well as management implications. Special emphasis will be placed on the role of cultural ecosystem services.

Despite the minimal attention that physicians typically pay to dreams, the assessment of dreaming can be of diagnostic interest and have management implications. This chapter reviews the world literature on dream abnormalities of clinical neurological significance, starting with the classical concept of the Charcot–Wilbrand syndrome (anoneira). This and the other recognized disorders are broadly classified here under headings of “deficits” and “excesses” of dreaming. Also reviewed are major trends in the neuroimaging and neurophysiological literature regarding dreams and their relationship to REM sleep. Lastly, the chapter reviews the putative role of microarousals and controversies regarding dopamine and acetylcholine in the generation of dreams.

Abstract. With the proliferation of the geospatial technologies on the Internet, the role of geo-portals (i.e. gateways to Spatial Data Infrastructures) in the area of wildfires management emerges. However, keyword-based techniques often frustrate users when looking for data of interest in geo-portal environments, while little attention has been paid to shift from the conventional keyword-based to navigation-based mechanisms. The presented OntoFire system is an ontology-based geo-portal about wildfires. Through the proposed navigation mechanisms, the relationships between the data can be discovered, which would otherwise not be possible when using conventional querying techniques alone. End users can use the browsing interface to find resources of interest by using the navigation mechanisms provided. Data providers can use the publishing interface to submit new metadata, modify metadata or removing metadata in/from the catalogue. The proposed approach can improve the discovery of valuable information that is necessary to set priorities for disaster mitigation and prevention strategies. OntoFire aspires to be a focal point of integration and management of a very large amount of information, contributing in this way to the dissemination of knowledge and to the preparedness of the operational stakeholders.

Small Business Social Responsibility

This chapter deepens the knowledge of inter-firm collaborations to address sustainability issues between SMEs in adopting small business social responsibility (SBSR) approaches. The study investigates the role of formal network contracts (FNCs), where aspects of SBSR are formalized into legal agreements between the networkers. For this purpose, the authors identify three management implications declined as sub-variables: control, consensus, and consistency. Institutional theory and, specifically, isomorphism and normative theory of CSR are used as lenses through which to analyze the results. The methodology applied is a deductive qualitative content analysis, while results are shown using an Euclidean perspective. The study discovers the use of FNCs to clearly govern consistency and consensus, more than to control and audit sustainability herein the network. In addition, it demonstrates a relation between network size and use of the tool.

Big Brother

Monitoring urban growth and land-use change is an important issue for sustainable infrastructure planning. Rapid urban development, sprawl and increasing population pressure, particularly in developing nations, are resulting in deterioration of infrastructure facilities; loss of productive agricultural lands and open spaces; pollution; health hazards; and micro-climatic changes. In addressing these issues effectively, it is crucial to collect up-to-date and accurate data and monitor the changing environment at regular intervals. This chapter discusses the role of geospatial technologies for mapping and monitoring the changing environment and urban structure, where such technologies are highly useful for sustainable infrastructure planning and provision.
