The Phylogenetic Moment-A New Diversity Measure, with Procedures for Measurement and Optimisation
The measurement of diversity in biological systems is an increasingly important requirement in environmental planning at regional, national, and even international levels. Phylogenetic diversity indicates the biological variety present in a set of species by reference to the phylogenetic relationships amongst the species. A new diversity measure is proposed which for a given group indicates how well a given set of extant taxa represent the group …
Grid Cell Representation of Soil Maps
The paper describes a continental scale grid cell data set containing soil descriptions. The accuracy of these descriptions and how they change as a result of grid cell aggregation are described
Estimating proximate populations for an extensive set of locations in Australia
The paper reports the use of Australian Resources Information System to calculate two proximate populations (people living within (i) 150 and (ii) 500 km) for the centroids of each of 3,000 half by half degree geodetic grid cells covering Australia. The use of proximate population data is exemplified by computing a map of the eighteen regions collectively containing a maximum fraction of the Australian population." The data used are from the 1981…
