Recruitment in behavioral ecology. In behavioral ecology and studies of animal communication, recruitment is the process by which individuals in a social group direct other individuals to do certain tasks. [2] This is often achieved through the use of recruitment pheromones that direct anywhere from one to several hundred individuals to ...
Microbial population biology, in practice, is the application of population ecology and population genetics toward understanding the ecology and evolution of bacteria, archaebacteria, microscopic fungi (such as yeasts ), additional microscopic eukaryotes (e.g., "protozoa" and algae ), and viruses . Microbial population biology also encompasses ...
Demic diffusion, as opposed to trans-cultural diffusion, is a demographic term referring to a migratory model, developed by Luigi Luca Cavalli-Sforza, of population diffusion into and across an area that had been previously uninhabited by that group and possibly but not necessarily displacing, replacing, or intermixing with an existing ...

Today, Mesopotamia is known as present-day Iraq and north-eastern Syria. [1] [2] In the broader sense, the historical region of Mesopotamia also includes parts of present-day Iran, Turkey, and ...
Zero population growth, sometimes abbreviated ZPG, is a condition of demographic balance where the number of people in a specified population neither grows nor declines; that is, the number of births plus in-migrants equals the number of deaths plus out-migrants. [1] ZPG has been a prominent political movement since the 1960s.
Deme (biology) In biology, a deme, in the strict sense, is a group of individuals that belong to the same taxonomic group. [1] However, when biologists, and especially ecologists, use the term ‘deme’ they usually refer to it as the definition of a gamodeme: [2] a local group of individuals (from the same taxon) that interbreed with each ...
Human population growth, industrialization, land development, overconsumption and combustion of fossil fuels have led to environmental destruction and pollution that significantly contributes to the ongoing mass extinction of other forms of life. Biology Anatomy and physiology
