Terra Psidium Wiki



Welcome to the Terra Psidium Wiki
Terra Psidium is a speculative biology project investigating invasive species and nature's ability to recover from mass extinctions. It deals with a hypothetical scenario rather than a proposed change in the past, though it does also deal with future predictions. The scenario is that after an undefined event, the only species left on Earth are introduced to their unnatural habitat by pre-event humanity.

Scenario
Humans, and all evidence for them (with exception to species introductions), as well as all other species on Earth, have instantaneously vanished--except for invasive and introduced species. These are left in the countries that they were introduced to. A population only remains if it is self-sustaining, wild, is or is descended from a population introduced or spread by man to a new location (including in ancient times).

This sudden loss of species leaves  many niches left unfilled, giving fauna and flora alike to evolve into odd new forms  In addition, organisms are living in climates they have not adapted to, with other species they haven't evolved beside, resulting in very odd ecosystems.

1000 years hence (1kyh)
Over the course of 1000 years, the remaining species of Earth have spread to fill whatever niches they can. Populations have stabilised and most species have spread beyond the places that they were introduced to. Even the countries which were left most barren have been invaded, and once again filled with life - to some extent. While the species of Terra Psidium at this time are all recognisable, they're on a backdrop you'd never expect to see them against - like Jeremy Clarkson at a decathlon.
