extinct
Scientests use the term bioinvasion to describe the introuduction of foreign species into native ecosystems.
Spatial isolation is also known by the term geographic isolation. It occurs when different populations of a particular species become separated geographically and can no longer reproduce among themselves. This narrowing of the genetic pool often leads to birth of a new species that is essentially a unique subset of the original species.
The term would be spelled "catastrophizing" but is not formal English.The verb form from the noun catastrophe may be spelled catastrophize or catastrophise, an infomal psychological term (and slang word) meaning to see, imagine, or describe things in a way that is worse than actually exists.
i believe the term would be: "peace".

keystone species
The term used to describe the process for a new species developing from an existing species is "speciation." This process occurs when a population becomes reproductively isolated from the original species, leading to the accumulation of differences over time that eventually result in the formation of a distinct new species.
Speciation is the best term to describe a new species developing from an existing one.
freedman
Completely eliminated (as undesirable); uprooted. Within ecology, a species or other taxon which no longer exists in the wild of a certain area, but can be found elsewhere in the world, is extirpated or locally extinct.
