range
In arithmetic, the range of a set of data is the difference between the largest and smallest values
dispersion
In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency
metapopulations
A metapopulation consists of a group of spatially separated populations of the same species which interact at some level
wildlife corridors
A wildlife corridor, habitat corridor, or green corridor is an area of habitat connecting wildlife populations separated by human activities or structures
biome
A biome /ˈbaɪoʊm/ is a formation of plants and animals that have common characteristics due to similar climates and can be found over a range of continents
population density
Population density is a measurement of population per unit area or unit volume; it is a quantity of type number density
Parasitism
In biology/ecology, parasitism is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host
colonization
Colonization is an ongoing process by which a central system of power dominates the surrounding land and its components
zygotes
A zygote , is a eukaryotic cell formed by a fertilization event between two gametes
