POPULATION ECOLOGY

Population ecology is about acknowledging the factors due to which the amphibians are in danger of going extinct over time. Few specific species have been endangered, vulnerable to the rapid changes of the ecosystem, whereas others are increasing in population. Moreover, the how, why and which factors cause the extinction of the population evaluation is known as the population ecology. A dynamic change of population growth, regarding demographic atmosphere, regulations, development from the past roots has been discussed through this article.

Population Ecology

The population is termed as the subset of an individual species in a demographic region, and its reproduction rate in that occupied area, as well as interbreeding. Geographical circumstances create a barrier for some species to be able to sustain there, whereas it presents a suitable condition for other several species. Some animals or plants are known to occupy smaller spaces, where one can see an increase in the population easily, whereas humans need vast expanse of land. Population ecologists evaluate the human species growth rate to determine the environmental factors which change the ecosystem in the present arena. In addition, from a small species to plants and animals to the human breed ratio has been applied for population ecology analysis. 

Population Ecology Definition

Seeking spatial and temporal patterns of the distribution and abundance of each organism’s category is the essential activity of ecologists. A population can be defined as the individual counts of every biological species in a particular demographic area at a certain period. The density of population analysis can be termed population ecology. In order to evaluate the scenario of biological species’ life cycle including the fertilized eggs, development of that species on the varied process, integration process, unitary and adult organism, ecological surveys need to be done. It can be predicted through a scientific process, which explains the size of population through measuring adult units and juvenile progeny. The elasticity of population can be changed due to the process of “birth, death, immigration and emigration” ratio of a particular region. It explains the reasons for differentiation of the biological species and their extinctions over time. The study which identifies and regulates the possibility of distribution and abundance to the environment is defined as population ecology. 

Characteristics of Population Ecology

Representing the population size of a particular organism species in a certain place and their habitat residence measurement is the prior aspect of population ecology. The characteristics of population ecology can be measured through major three perspectives, such as genetic variations in a certain place, density and growth of population, and population regulations.

Genetic variations in a certain place:

Population Size: ecologists determine the size of the population by using the letter “N”, which is equal to the total habitat individual in that place. It explains the generic variations of organisms in that local demographic region, it also measures the genetic distinction regarding the differences based on “morphology, physiology, behavior and life history” which expressed the effects on population size. Ecology defines the affecting factors of each habitat’s survival progress and determines the issues which result in the abolition of certain species. A large population can be found in a disciplinary ecosystem, which is explained through reproduction approach depending on the sexual and asexual mode of reproduction effects. 

Population Density: the growth of population and its longevity depends on various distinctive factors in diverse geographical areas. It is important to measure the interaction ratio in that particular geographical region to evaluate the density of population. A place where a large population could easily interact with the environment, one can find a high-density population there. On the other hand, a low-density population is found in regions which are smaller in size, controlling the multiplication of organisms due to the lack of sustaining climate.

Population Dispersion: it refers to the distribution of individual organisms to varied locations based on the climate, ecological conditions, and reproduction methods. uniform dispersion indicates the scenario where one certain distinctive species can survive for a long and reproduce uniformly. In contrast, random dispersion refers to the immigration process which can be implanted through migration. There is no particular demographic circle and influence. On the other hand, clustered dispersion reflects the norms of production with a certain feature in a particular area. 

Conclusion

The life history of varied species in the environment helps to analyse the ecosystem and it is dependent on the growth, development, reproduction, and survival factors. The variation of the life history of each species can be accumulated through the ecology rates. Population ecology helps to understand the conditions of distributing factors in diverse geographical regions. In addition, the development, and predictive quality can be explained through this system regarding the inhabitant’s sustainability. Population ecology deals with the interaction between the individual species and their reaction to the environment.
