Population Density Research Papers Samples For Students

Population density is the number of people per unit area. It is a statistic frequently used to compare places worldwide. It is simply the number of people per square mile or the number of people per square kilometre.
Mathematically, this is arrived at by dividing the total area population by the area of land in square miles or square kilometres. It is a rough estimate of population distribution across an area. Population density can always be calculated once the land size and the total population of that area is known. From the world population figures, it was seen that Asia ...

Introduction

In the starting years of twentieth century the world population reached to million people and it can be said that developing countries were the major contributors. Asian countries including china contributed to 80% of the total population growth in the world. Majority of the researchers believe that population growth is strongly connected to the economic development in a country. It is also deemed the relation between these two is a close one and in other words it can be said that population plays an integral role in economic growth (Bloom 1997). There is a wide range of argument about the impact of ...

This paper is about the sexual selection. It shows how sexual selection has an enormous effect on the evolutionary changes with different characteristics selected for and against (Brewster and Houde 2003, p. 1057). The common result of this phenomenon is the directional selection. This is where phenotypes indicate high fitness level resulting to an increased number of offspring in this phenotype (Brooks and Endler 2001, p. 1007). By increasing the rate of directional selection and opportunity for the sexual selection methods, the ability of survival and the average fitness will increase. The processes involve dauer processes. Dauer entry is ...

1. Describe the concepts of territoriality, privacy, and personal space.
The traditional explanation of territoriality was emphasized on the marking off and protection of a physical border line from invasion by those of similar kind. Of late, the definition has been modernized to refer explicitly to oversee the space around an organism, particularly the distance between themselves as well as with others of the same species (Linda 2010). In humans, territoriality falls inside three domains: the public, primary and secondary. Public territories are open to any person. They pursue the basis of first-come first-serve. Primary territories are that are ...

Mathematical model.

In 1985, Kallen, Arcuri and Murray (377-393) presented a simple mathematical model for the spread of the rabies epidemics to approximate the minimum width of a break and enable the control of the spatial progression of rabies.

Features and assumptions of the model.

The model developed by Kallen, Arcuri and Murray (377-393) was based on a deterministic approach where the fox populations were categorized into two groups, namely infective and susceptible foxes. In this classification, the infective foxes included those with rabies virus present in their saliva while the susceptible ones included those without traces of rabies virus in their saliva. One of the assumptions ...
