Macroecology is the subfield of ecology which deals with the study of relationships between organisms and their environment at large spatial scales to characterise and explain statistical patterns of abundance, distribution and diversity. The term was coined by James Brown of the University of New Mexico and Brian Maurer of Michigan State University in a 1989 paper in Science. Ecology can mean either: the natural environment, or an analysis or study using the principles and methods of ecological science. ... James Hemphill Brown, an ecologist, is Distinguished Professor of Biology at the University of New Mexico. ... The University of New Mexico (UNM) is a public university in Albuquerque, New Mexico. ... Michigan State University is a university in East Lansing, Michigan near the state capital of Lansing. ... 1989 is a common year starting on Sunday of the Gregorian calendar. ...

Macroecology approaches the idea of studying ecosystems using a "top down" approach. It seeks understanding through the study of the properties of the system as a whole; Kevin Gaston and Tim Blackburn make the analogy to seeing the forest for the trees (literally). In ecology, an ecosystem is a community of organisms (plant, animal and other living organisms - also referred as biocenose) together with their environment (or biotope), functioning as a unit. ...

Classic ecological questions amenable to study through the techniques of macroecology include questions of species richness and the species-area curve, range size, body size and species abundance. For example, the relationship between abundance and range size (why species that maintain large local population sizes tend to be widely distributed, while species that are less abundant tend to have restricted ranges) has received much attention. Species Richness is a measure of biodiversity. ...
