Population is all the inhabitants that are living in an area or country. Overcrowding and overpopulation is becoming a big issue on the planet Earth due to the fact that resources are becoming limited. Some populations are distributed very spread out, while others live in very dense spots. Populations are affected everyday in different ways, and dependent or independent density comes from this. Organisms leaving or coming into the area also have an affect on the population, and the carrying capacity portrays how many organisims can stay in that area.
Populations and Growth
All the populations in Haiti were affected by the 2010 Earthquake. The most affected, although, was the human population in Haiti, as they were the keystone species who had the most organism members. This means that the density of the humans was very high, and the carrying capacity was very near as you could tell from the demand of resources. The carrying capacity had been lowered after the earthquake because space and resources were destroyed and reduced, therefore the area could not support as many organisms as it used to. The geographic range of the human population was obviously all of Haiti, excluding the mountain range that seperates Haiti and the Dominican Republic. The humans were and still are distributed in scattered/random pattern at a national level, and a clumped pattern when looking at things a little closer.
After the earthquake, the birth rate in Haiti stayed the same, but the death rate increased. Immigration, or organisms moving into the area, lowered into the none category. This is because no people would want to stay in a place where the resources cannot provide a healthy life to them, and many people who went to Haiti on mission help trips usually were only there for a visit. Emmigration was affected, but at a very small scale. Few of the moderately wealthy people in Haiti bought cheap tickets to get away from Haiti after the earthquake, but most people there could not afford this freedom. Many of them are not allowed to anyway since they don't have proper documents, and they don't have the reources to make it happen either. Emmigration also occured at a small scale with birds and fish in the Haiti region. All of these rates put together caused the population to decrease since more people died than before the earthquake and no people left or came. Many people died during the earthquake, after the earthquake, from injuries or sickness, and hunger. The death rate and no immigration caused the population to decrease by a tenfold.
Exponential growth is when there are ideal conditions and unlimited resources that cause the population to grow, and the bigger it gets the faster it grows.The population in Haiti had experienced exponential growth 10 years ago when the country started to get a better economy since they were not affected by a natural disaster for four years, but this leveled off again after the 2010 earthquake. After the earthquake, Haiti was in a worse condition than it was in 2000. Logistic growth, or the growth pattern after exponential growth that happens when it levels off, is happening right now in Haiti. It increases in 2000, but now it is leveling off and decreasing again. It will go back up once the community starts cycling again and the conditions in Haiti get better.
As well as exponential and logistic growth, limiting factors also control the population in an area. The limiting factors determine the carrying capacity in an area. There are two different types of limiting factors: density dependent and density independent. The density dependent factor is when the density of the population has an affect on the area, and the humans have had more competition within other organisms and their parasitic relationships have increased. It is now overcrowded, and disease is now spread more easily, and these are all factors that control the population and are affected by the amount of organisms. The density dependent factor, or the factor that the density of the population has no affect on, was obviously the earthquake itself in this case. In any other case, it would also be some sort of natural disaster. The earthquake's after effects like the drought and the lowered food supply also can be density independent limiting factors. The limiting factors both affected and were effected by the Haiti 2010 Earthquake.
