The trainer at the zoo was telling me that they transfer the younger gorillas to other zoos to mate with other families so as to propagate the zoo populations. The last time one of the daughters got transferred, the entire family sulked around for a few months. They were shown pictures and video of the daughter in the new habitat, but the trainer said she's unsure if they understand that.
This happens with bulls. When they are separated they spend weeks searching for each other and it is a constant bellowing. Whether the ones left behind were aware that the others had been taken to slaughter, it is impossible to tell.

In order to have a mourning period (as opposed to just sniffing a corpse and recognizing death), the animal must be able to comprehend that the other animal was born, lived, and is now dead and not coming back.
This does not tell us how they handle the concept of a life on an individual level in their day to day experience, but I think it does tell us that they have a concept of it.
I agree on a very basic understanding. The fact that they are aware that this happens to others of their same species in no way does it make them think that one day it will happen to them.

To me it causes us a great deal of difficulties.
