1 It is required for groupings that are not coded as base groupings.
Theoretical models suggest that where strong spatial segregation leads to distinct sub-groupings within a population, as is the case for territorial species, inter-species transmission may be the dominant transmission pathway, so that the presence of an alternative host is required for pathogen establishment [2], [4].
A more robust critique of the sub-grouping perspective requires consideration of the predictions that a sub-grouping model makes, and investigation of data related to these predictions.
The proposed rate one MRP and multirate MRP can always achieve full transmit diversity and optimal system performance for arbitrary number of antennas, subcarrier intervals, and subcarrier groupings, with limited channel knowledge required by the transmit antennas.
To understand the underlying mechanisms for these differences among functional plant groups, further investigations would be required, perhaps with larger sets of plant species and groupings based on different functional traits such as root characteristics and aerenchyma formation.
This scheme calibrates the groupings (clusters) for the required evolutionary granularity, and selects against intermediate clusters partial groupings which are artifacts of clustering into a binary tree.
In reality, the lines between the groupings are fungible, and the specific duties required of each are cloudy at best.
For chemicals capable of inducing MN, a classification into aneugens and clastogens suggests itself as a starting point, but additional information will be required to arrive at finer groupings.
Therefore, groupings such as genovars require a combination of functional and taxonomic diversity measures to understand their potential for pathogenicity or other functional features.
In fact the only assumption required is that a rational sampling and sub-grouping regime is used [ 11].
