Competition among members of the same species is known as intraspecific competition, while competition between individuals of different species is known as interspecific competition. Competition is not always straightforward, and can occur in both a direct and indirect fashion. According to the competitive exclusion principle, species less suited to compete for resources should either adapt or die out, although competitive exclusion is rarely found in natural ecosystems.
THE HISTORY OF VERACRUZ. By John P. Schmal. The state of Veracruz, located along the eastern Gulf Coast of the Mexican Republic, has a population of 6,856,415 people, representing 7.39% of Mexico's national population in 1990. Politically divided into 203 municipios, the state has an area of 27,759 square miles (71,896 square kilometers).
The last population census run across Mexico in the year 2015, reports Coahuila de Zaragoza as having 2,954,915 inhabitants, which, considering its size, means that the state has a very low density, in fact as low as only 15 persons per square kilometer. Coahuila's population is mainly made up of Criollos along with Mestizos.
