    Notes: Ecological indicators have widespread appeal to scientists, environmental managers, and the general public. Indicators have long been used to detect changes in nature, but the scientific maturation in indicator development primarily has occurred in the past 40 years. Currently, indicators are mainly used to assess the condition of the environment, as early-warning signals of ecological problems, and as barometers for trends in ecological resources. Use of ecological indicators requires clearly stated objectives; the recognition of spatial and tempor al scales; assessments of statistical variability, precision, and accuracy; linkages with specific stressors; and coupling with economic and social indicators. Legislatively mandated use of ecological indicators occurs in many countries worldwide and is included in international accords. As scientific advancements and innovation in the development and use of ecological indicators continue through applications of molecular biology, computer technology such as geographic information systems, data management such as bioinformatics, and remote sensing, our ability to apply ecological indicators to detect signals of environmental change will be substantially enhanced.

    Carbon budgets for a phytoplanktivorous fish fed three different unialgal populations (1985)
    Springer
    Oecologia 66 (1985), S. 246-249 
    Details
    ISSN: 1432-1939

    Topics: Biology
    Notes: Summary The filter feeding blue tilapia, Tilapia aurea, was fed three different algae. Blue tilapia ingestion of two green algae, Chlamydomonas sp. and Ankistrodesmus falcatus and the filamentous blue-green alga, Anabaena flos-aquae, ranged from 21%–89% of the available cells. There were significant differences in the assimilation of algal carbon by the fish depending on the alga fed; A. flos-aquae was the easiest to assimilate (83%). The fish respired significantly less of the Chlamydomonas sp. ingested carbon (15%). The gross growth efficiency of fishes fed either green alga was not significantly different (22%–24%), but these efficiencies were significantly less than the gross growth efficiency of fish fed A. flos-aquae (46%). The carbon budgets for fish feeding on the green algae were similar to that constructed from the literature for a congener fed a mixed algae diet. However, the assimilation component of the budget for blue tilapia fed A. flos-aquae was 2 times greater than that of the literature budget.

    Growth of a grazing phytoplanktivorous fish and growth enhancement of the grazed alga (1985)
    Springer
    Oecologia 67 (1985), S. 132-136 
    Details
    ISSN: 1432-1939
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The blue tilapia, Tilapia aurea, consumes the green alga, Ankistrodesmus falcatus, with some algal cells passing through the gut in viable condition. Grazing fish grew and the grazed algal populations had enhanced densities compared to ungrazed populations. Algal growth enhancement was not produced by either bacteria or fish excreting an algal limiting nutrient. Possible ingestion and digestion of bacterial cells by the fish might release nutrients to the algal cells that were otherwise unavailable. Blue tilapia may be affecting algal communities in ways other than by passive size selection. Enhancement of algal growth by the blue tilapia could have important implications for understanding the phytoplankton dynamics in waters containing blue tilapia.

    Notes: Abstract In this paper, I address the question, “Who are the political and ideological opponents of liberalism?” I suggest that Dworkin's way of dividing liberals from their conservative opponents over the issue of pluralism fails to get at the main issue of redistribution. But arguments for and against redistribution share a common pluralistic conception of politics and morals, viz., that they are to be conceived in terms of an agreement amongst autonomous individuals who are each trying to maximize their own welfares. I argue that this ignores our relations with the non-autonomous and is parasitic on a wider and more generous notion of the political and moral community. I suggest that such a community must form a focus of its members' loyalties and an end (telos) for human virtues. I then draw some lessons for business ethics, arguing that it is an essentially specialized enterprise which ought not to used to model moral and political relations in general.

    Interactions between a phytoplanktivorous fish, Oreochromis aureus, and two unialgal forage populations (1987)

    Notes: Synopsis Juvenile blue tilapia, Oreochromis aureus, consume both the motile green alga, Chlamydomonas sp., and the filamentous blue-green alga, Anabaena sp. Results from a grazing experiment showed little difference between the densities of grazed and ungrazed populations of Chlamydomonas, but did show a decrease in density and growth rate in the grazed Anabaena population relative to an ungrazed population. Tilapia ingesting Chlamydomonas lost weight, similar to the weight loss of unfed control fish. However, fish fed Anabaena gained weight. This study provides further evidence that blue tilapia grazing may structure phytoplankton communities directly, and their grazing could shift phytoplankton communities from dominance by large blue-green algae towards dominance by green algae.
