### people | population:

African population
* are very young.
* is very dependent on wild and domesticated plant resources.

Amphibian population
* declines in British Columbia.
* tend to benefit during the early stages of development
  - fluctuate a lot

Animal population
* All animal populations vary somewhat based on weather, food, disease, predation, and reproduction.
* change over time as the results of births, deaths, and dispersals.
* consist of healthy, smart members because everyone else died or was eaten.
* drop dramatically as a result.
* respond with increased birth and survival rates and decreased emigration.

Bacterial population
* appear to decline rapidly in soil.
* increases exponentially or logarithmically.
* multiply at incredibly high rates.
* reproduce much faster and produce more offspring than humans.
* show distinct spatial distribution patterns.
* subjected to heat or antimicrobial chemicals usually die at a constant rate.

Biological population
* are always finite in size.
* bring in a greater level of complexity and uncertainty beyond the organism.

Coastal population
* Some coastal populations live in salt marshes.
* commute daily to forage in salt marshes and on tidal mudflats.
* forage daily in salt marshes and on tidal mudflats.

Different population
* retain different level of genetic diversity.
* spawn at different times and in different streams.
* tend to suffer from different types of glaucoma.

### people | population:

Feral population
* are distributed throughout the tropics
  - frequent and distributed over the whole Switzerland
  - mostly small in number and threatened by human encroachment
* can also pass on diseases to domestic herds.
+ Feral organism, Harmful and helpful effects of feral organisms, Economic harm: Animals :: Plants
  * Feral animals compete for food with domestic livestock. Though hotly disputed, some cite as an example the competition between feral horses and cattle in the western United States. Another example is of goats competing with cattle in Australia, or goats that damage trees and vegetation in environmentally-stressed regions of Africa. Accidental crossbreeding by feral animals may result in harm to breeding programs of pedigreed animals. Their presence may also excite domestic animals and push them to escape. Feral populations can also pass on diseases to domestic herds.

Finite population
* can behave very differently from infinite populations.
* induce metastability in evolutionary search.

Fungal population
* increase on certain soils where peanuts follow peanuts.
* tend to be higher in areas that have a northwest exposure.

Future population
* aging, like future population growth, is virtually certain to occur.
* is forecast by estimating by age group the survivors from the present population.

Global population
* increases mean greater demands for wise and fair uses of natural resources.
* rises continuously throughout the century
  - during the first half of the century, peaks mid-century, then declines

Heavy population
* can kill branches or entire plants
  - small plants and reduce kernel size in larger plants
  - severely defoliate and kill plants
* cause plants to yellow and wilt.
* produce a lot of honeydew, which leads to the development of sooty mold.

High population
* can cause leaf drop
  - remove nearly all the new and old needles in a single season
* mean that there is an increased chance of one animal infecting another.
* reduce quality and quantity of flowers.
* stunt or kill plants.
* tend to force the crop into stress more quickly when moisture supply is limited.
