Overview: Earth’s Fluctuating Populations • To understand human population growth‚ we must consider general principles of population ecology • Population ecology is the study of populations in relation to environment‚ including environmental influences on density and distribution‚ age structure‚ and population size • The fur seal population of St. Paul Island‚ off the coast of Alaska‚ has experienced dramatic fluctuations in size Dynamic biological processes influence population density‚ dispersion

Introduction The challenge of reaching both economic and environmental sustainability in the face of the rapid population growth of the world is frightening to developing country governments and to members of the donor community. What makes this challenge so tough is that sustainability and population growth are not independent problems. They are very well related to each other. They cannot be secluded from one another and they cannot be addressed separately. The solution needs comprehension not

In ecology‚ competition occurs between any organisms living in a mutual habitat. Competition can either be harmful or helpful to each organism‚ whether it is for food‚ water‚ shelter‚ etc. There are two basic types of competition: intraspecific competition or interspecific competition. Intraspecific competition is the competition that occurs between the individuals of the same species (T. Smith & R. Smith pg. 222). On the other hand‚ interspecific competition is the competition that occurs between

In its evolution‚ the internet has been greatly affected by emerging communication technologies such as online publishing software and communications technology. Consequently‚ these factors have led it to be promoted as the new public sphere in the way it has become a facilitator of public discussion and great social change. By Habermas’s definition‚ the public sphere is ‘a realm of our social life in which something approaching public opinion can be formed’ (Habermas‚ 1974‚ p. 49). This is particularly

Ecology Ecology is the study of interactions between organisms and the living and non-living components of their environment. It involves collecting information about organisms and observing their life patterns as well. Ecology is a science that seeks to explain why patterns occur the way they do. Interdependence is a key component of biology‚ meaning that all the organism interact with one another in various ways. Its very crucial for organisms since they all depend on one another
