Certain events can only take place on the world when playing with the Biospheres feature enabled, instead of the Biomass feature. In order for these events to take place, It also need to have, or have had, species alive on the world.
Harsh Winter[]
A particularly harsh winter has temporarily reduced the health of [species] by [-%]
Temporary health reduction for that species, not visible in 'modifier' part of a species' health calculations.
Poaching[]
Poachers have begun aggressively targeting [species] specimens, resulting in a permanent reduction of the species health by [-%].
Permanent health reduction for that species, visible in 'modifier' part of a species' health calculations.
Rough Weather[]
A terrible storm has temporarily reduced the health of the [species] by [-%]
The same effect as Harsh Winter.
Favorable Summer[]
A particularly favorable summer has temporarily boosted the health of the [species] by [+%].
This can be good, but if playing on Expert difficulty, may need to stop this from happening by culling the species a little bit, as don't want this species to eat species that support it to extinction.
Popular Pet[]
After a popular celebrity started raving about their new [species], people all across (the) [world] have started getting their own, resulting in a [+%] boost to its health.
The popular pet event does indeed provide a permanent boost to the species health.
Resurrection[]
A wild [species] has been discovered surviving on the surface of (the) [world]! Previously thought to be extinct, our scientists are thrilled to announce that the [species] has not completely died out after all!
An extinct species comes back alive.
Prerequisite: Have a species that's gone extinct.
Mutation[]
Scientists have discovered a very unusual [species] during a routine conservation sweep. Further investigation revealed that the species has mutated, spawning a sister species that is being called [-species]!
Adds a new species with a fixed name and randomly alter one of their genes.
New Niche[]
Specimens of the [species] have found a new niche in their local ecosystem. Our scientists are predicting that it will results in a [+%] boost to the species overall health!
This can be good, but if playing on Expert difficulty, may need to stop this from happening by culling the species a little bit, as don't want this species to eat species that support it to extinction. The change in health is represented within the 'modifier' part of species' health calculations.
New Disease[]
A new disease has struck the [species], reducing its health by [-%].
This is a modifier event so the negative health effect is permanent.
Pest[]
People on [world] have begun to think of the [species] as a pest, and many people are killing them whenever they can. This has resulted in a [-%] penalty to the species health
This is a modifier event so the negative health effect is permanent.
Anthropocentric Adaptation[]
Several [species] specimens have begun exhibiting anthropocentric behaviors, benefiting from nearby human populations to boost their own wellbeing by as much as [+%].
This can be good, but if playing on Expert difficulty, may need to stop this from happening by culling the species a little bit, as don't want this species to eat species that support it to extinction. The change in health is represented within the 'modifier' part of species' health calculations.
