ISSN: 1432-1939Source: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Summary Observations of tussock grasses (mainly Poa species) and tree seedlings (Eucalyptus pauciflora) growing near treeline suggested that the tussocks may physically protect and compete with the tree seedlings. An analysis of nearest neighbour data from sites burnt in 1972–3 showed the there is a minimum separation between seedlings and tussocks, indicating that competition is taking place. Correlation and principal components analyses show that seedlings growing close to tussocks tend to be taller, with fewer stems and leaves than those growing further away. This same trend from tall, few-stemmed individuals to shorter multistemmed individuals also occurs with an increase in altitude. It is concluded that the trend in habit is related to exposure to environmental extremes. The concept of the regeneration niche and its application to E. pauciflora seedlings is discussed.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5052Keywords: Disturbance ; Dynamics ; Fire ; Models ; Succession ; VegetationSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Summary A comprehensive scheme is presented which provides qualitative models of vegetation dynamics in communities subject to recurrent disturbance. The scheme has been derived to deal mainly with terrestrial communities dominated by higher plants, but may be more widely applicable. The scheme utilizes a small number of life history attributes termed ‘vital attributes’ which pertain to the potentially dominant species in a particular community. Three main groups of vital attributes are recognized, relating to the method of persistence of species during a disturbance and to their subsequent arrival, to their ability to establish and grow to maturity following the disturbance, and to the time taken for them to reach critical stages in their life history. In the application of the scheme, each major species is first categorized into a ‘species type’, determined by its specific attributes in the first two vital attribute groups. The interaction between various species, based on their species types and life stage attributes, then yields a replacement sequence which depicts the major shifts in composition and dominance which occur following a disturbance. Although 30 species types are recognized, only 15 distinct patterns of behaviour are displayed in replacement sequences. Examples of replacement sequences for two different forest communities are provided. The degree to which vital attributes are robust properties of a species is explored in relation to different disturbance frequencies and intensities, and to the seasonal time of disturbance.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5052Keywords: Expert system ; Knowledge-based system ; ModellingSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract An area of artificial intelligence known as experts systems (or knowledge-based systems) is being applied in many areas of science, technology and commerce. It is likely that the techniques will have an impact on vegetation science and ecology in general. This paper discusses some of those impacts and concludes that the main effects will be in areas of applied ecology especially where ecological expertise is needed either quickly (e.g. disaster management) or across a wide range of ecological disciplines (e.g. land management decisions). Expert systems will provide ecologists with valuable tools for managing data and interacting with other fields of expertise. The impact of expert systems on ecological theory will depend on the degree to which ‘deep knowledge’ (i.e. knowledge based on first principles rather than on more empirical rules) is used in formulating knowledge bases.Type of Medium: Electronic ResourceURL: -

Identification of individual proteins was done by reference to their position in protein band profiles by polyacrylamide gel electrophoresis (PAGE) of the crude material. This permitted a rapid and facile assignment of quantitative values for these three parameters to all the major protein components in these materials. Because it is the indigenous proteins in expression systems that will form the bulk of any impurities in the product, once the values of these parameters are known for any target recombinant protein, the data obtained will enable appropriate expression systems to be chosen for minimizing amounts of potential contaminants and reducing downstream processing requirements and costs. The data will also indicate which fractionation steps (i.e., charge, size or hydrophobicity-based) are likely to be best for distinguishing between target and contaminant proteins, thus aiding and early removal of the maximum quantities of undesired protein to bring subsequent bioseparation steps down in scale and cost and up in terms of efficiency. © 1994 John Wiley & Sons, Inc.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL:
