Biology and consumer behaviour Biology and consumer behaviour Consumer behaviour is the study of the motivations surrounding a purchase of a product or service. It has been linked to the field of psychology, sociology and economics in attempts to analyse when, why, where and how people purchase in the way that they do. However, little literature has considered the link between our consumption behaviour and the basics of our being, our biology. Segmentation by biological-driven demographics such as sex and age are already popular and pervasive in marketing. As more knowledge and research is known, targeting based on consumers' biology is of growing interest
Body size and species richness then a simple explanation of why there are more small species on earth would be because they speciate faster. However, a recent analysis by Cardillo and colleagues (2003) revealed that body size did not influence the speciation rates of Australia's mammals. Similarly, a study using birds failed to demonstrate that body size and speciation rates were negatively correlated (Nee et al. 1992). It is known that extinction risk is directly correlated to the size of a species population. Small populations tend to go extinct more frequently than large ones (MacArthur and Wilson, 1967). As large species require more daily resources
