I like how this snippet gives us a short preview. If there was any part of this for someone to take a quick glance at and know what it was about this is the perfect part. Of course they would have to add the part of the cougars but I think this gives great representation.

I wasn't sure what genetic source-sink dynamics had meant but from my search I found that its where when we have areas that have more birth rates than death rates immigrate to areas that have low birth rates to high death rates. Basically these areas rely on the animals immagrating for the others in this area to keep afloat.

I wonder why that is as well as when this started happening? What could be a factor into why they migrate at different rates
