In the course of investigations on the effect of chemical vapors on air-borne bacteria, a better understanding of the state of the air-borne organism was sought through studies on the nature and composition of certain experimental bacterial aerosols. It was felt that an appreciation of the physical characteristics of the air-borne particle would add to our understanding of the factors which det...

Landscape genetics aims to quantify the effect of landscape on gene flow. Broadly, the approach involves measuring genetic variation, quantifying landscape heterogeneity, and statistically testing the link between both genetic variation and landscape heterogeneity. This approach has been widely used by conservation biologists, for example to identify barriers restricting movement in threatened ...
