Introduction No single pattern of biodiversity has attracted ecologists more than the observed increase in species richness from the poles to the tropics (Pianka, 1966; Rohde, 1992; Rosenzweig & Sandlin, 1997; Gaston & Blackburn, 2000; Willig, Kaufman & Stevens, 2003; Hillebrand, 2004). An obstacle in the search for the primary cause of this latitudinal gradient is the ever-increasing number of...

The ElectroCore is a new particulate control technology which is intended to augment the performance of aging or underperforming ESPs. Unlike conventional electrostatic precipitators which collect particles on their surfaces, the ElectroCore acts as a separator thereby allowing it to overcome many of the common reentrainment problems. A pilot-scale Advanced ElectroCore Field Prototype was insta...

where a and b are constants. Indeed, such models can be used at a spectrum of spatial scales to describe spatial variance in the abundance of a single species at different times or in different regions and of different species across the same set of areas (Taylor et al. 1978; Taylor and Woiwod 1982). A second general pattern that has come to prominence more recently is that the proportion of ar...
