The concept of population is not exclusive to the field of Biology. We can find the ubiquitous use of the term “population” every now and then. Let’s try to understand and define the word “population” as per its usage. Let’s understand what population means in different fields of s...

Population Regulation in an Ecosystem With regard to the population size of a species and what factors may affect them, two factors have been defined. They are the density-dependent factors and the density-independent factors. Find out the differences between the two in this tutorial. Know how ...
By definition, endangered and threatened species have reduced population sizes, making them subject to the vagaries of genetic drift and also to inbreeding. Inbreeding is mating between genetically related individuals, and often leads to inbreeding depression, a reduction of health, vigor, and fertility...

In this topical review, we first summarize the relevant mathematical principles underlying heterogeneity in a large population before outlining the various definitions of "diversity" and providing examples of scientific topics in which its quantification plays an important role. We then review how ...
Density-independent factor is any force that affects the size of a population of living things regardless of the density of the population. They often arise from physical and chemical (rather than biological) phenomena. Examples include weather and clima
Despite the basic biological, chemical, and physical similarities found in all living things, adiversityof life exists not only among and betweenspeciesbut also within every naturalpopulation. The phenomenon of diversity has had a long history of study because so many of the variations that exist ...
