    Ecological objectives for management purposes: applying the Amoeba approach (1973)
    Springer
    Journal of aquatic ecosystem stress and recovery 2 (1973), S. 277-286 
    Details
    ISSN: 1573-5141
    Keywords: ecology ; objectives ; water management ; Amoeba-approach
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Dutch integral water management aims to restore and maintain healthy aquatic ecosystems, which can sustain most human uses. Clear ecological objectives are necessary. Sustainability of fundamental ecological values (production and yield, species diversity, and self-regulation) is assumed to be best preserved in the reference situation. This is the situation, in which human influence is minimal. A general method to present ecological information, the Amoeba approach is discussed. This approach uses selected species as representatives for the ecosystem. Criteria for the selection of species are discussed. For each species (target variable) the current situation, the reference situation, and estimated effects of measures can be found and plotted in an amoeba-like figure. The presentation is a simplification and is therefore easily understood by managers, politicians, and the public. It's application for some Dutch inland waters is discussed.

    Adenosine deaminase,Ada, is in mouse chromosome 2H3, and is not allelic with wasted,wst (1991)
    Springer
    Biochemical genetics 29 (1991), S. 537-544

    ISSN: 1573-4927
    Keywords: mouse ; adenosine deaminase ; mouse chromosome 2

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The adenosine deaminase locus (Ada) in the mouse has been localized byin situ hybridization to band 2H3. Linkage analysis of backcross data has shown thatAda is 13.8±2.7 cM from the coat texture mutant, ragged,Ra. From the results of earlier work (Abbott, C. M.,et al., Proc. Natl. Acad. Sci. USA 83:693, 1986), it had been suggested thatwst was a low-activity allele ofAda, but this cannot be so becauseAda andwst have been found to be nonallelic.
