Minchanka [31]

Answer:

Two terms might apply for this situation: "<u>jump dispersion</u>" and "human-assisted invasions".

Explanation:

  • Dispersion: It refers to the <em>change in an organism's range or distribution area</em>. Different ecological and biogeographical processes might be involved in organisms' dispersion. The term "<u>jump dispersion</u>" refers to a <em>few individuals in a short time that can cross a barrier and occupy a new area</em>. In this situation, the establishment is not always for sure. For this to happen, they must reproduce and start a new population of a certain size that can survive to the new conditions.
  • Biologic Invasions: It refers to <em>new species that establish in a new area far or out of their original distribution range</em>. Once established, these species might be <em>considered exotic or invasive, according to their reproductive rate, population growth, and interaction with native species</em>. Biologic invasions are <u><em>natural processes</em></u>, that occur in small groups of individuals that can expand to other ecosystems, and the appearing or despairing of barriers promotes their expansion.  <em>But these biologic invasions have accelerated by human beings</em>, referring to this as "<u>human-assisted invasions</u>". These are the cases in which <em>men transport species from one place to the other for different uses or purposes.</em>

It is <em>very common</em> for these species to <em>scape and start new populations</em> in the <em>new area</em>, where they <em>have </em><em>less environmental pressure</em> -fewer predators, more resources, better nitches- than in their origin area, which <em>favors their establishment</em>.

The exposed situation in the example is a case of "human-assisted invasions". It might also be considered as jump dispersion (because a few individuals of the species crossed a barrier and established in a new area) but assisted by humans.
