FinnZ [79.3K]

Answer:

Nuestro planeta esta habitada por numerosas <em>especies</em>, muchas de ellas extendidas en grandes y diversas zonas. Sin embargo, existen especies que habitan una sola <em>área/región</em> con características<em> ambientales</em> únicas para su desarrollo.

Explanation:  

Entre las miles de especies que habitan el planeta, muchas de ellas pueden estar ampliamente distribuidas, mostrando adaptaciones a una gran variedad de ambientes y hábitats, mientras que muchas otras solo se encuentran restringidas a determinadas areas o regiones particulares que presentan condiciones ambientales determinadas. Esta diferencia en distribución esta muy relacionada a la historia de la especie,  a la edad de la misma sobre la tierra, adaptaciones a los ambientes y capacidades reproductivas y de dispersión.

Dentro de la clasificación de especies de acuerdo a su distribución, podemos mencionar a las especies

  • nativas: aquellas que habitan y se distribuyen las áreas naturales donde se originaron,
  • endemicas: entran dentro del concepto de nativas, pero a parte se caracterizan por habitar <u><em>unicamente</em></u><em> una región en particular debido a las condiciones ambientales</em> que les son propicias para su desarrollo. Estas especies no pueden trasladarse a otras regiones.
  • exoticas: aquellas especies que salen de su area natural de distribución para habitar otras areas mas lejanas. Allí pueden establecerse e interactuar con especies nativas sin causar grandes daños.
  • invasoras: especies exoticas que llegan a otras areas, que se establecen y que tienen la capacidad de reproducirse a una tasa superior a la de las especies nativas, invadiendolas y desplazandolas. Interactuan con las especies nativas y causan daños importantes.

Los términos nativos, endemicos, exóticos son <em>relativos al área a la que se esté haciendo alusión</em>: un continente, un país, una región o un bioma.
