So what will happen if you introduce a hyper successful or super successful invasive foreign species like a snake into a habitat? but it really doesn't even matter that it's in mississippi.
00:21
It's just in any case what will happen if you introduce a foreign species that then does surprisingly super well, right? so let's say we have the foreign snake, okay? so this foreign snake eats these rodents and they eat these rodents very well to the point where these rodents can disappear, right? suddenly you have this whole web disappearing, right? so there's not enough food for the native snake.
01:02
So the native snake population is decimated.
01:04
Not enough food for the hawks and other raptors, for example.
01:08
They're decimated.
01:10
Whatever mid -sized or small sized carnivore that normally preys on these rodents are basically decimated.
01:17
And then these foreign snakes, if they're small enough, if they've decimated the rodent population, could start eating other species, right? and so we can have this collapse happening further and further.
01:34
The problem with successful foreign species in a native compared to successful foreign species in an environment where they out -compete native species is that typically when they're very successful they're called at some point invasive partially because what's happening here is that they disrupt the native ecosystem, in this case the food web, right? they can completely decimate certain native populations.
02:29
Not all, but some.
02:41
They can decimate their intended prey but as a side of the fact that like a...
02:49
Okay, so let's go back.
02:51
When they decimate certain native populations this damage is expounded tenfold if the species is a keystone species...
