[Basta-users] Question on survivorship for pre-emergence

[Ezequiel Fabiano]

Thanks. Let me see if I can re-formulate. The question is whether BaSTA
"assumes" that for example that cubs that are one month/year old have the
same survival probability as those that are a couple days old. The reason I
ask is that for certain species like the cheetahs a high mortality rate
prior the cubs leaving the "den", pre-emergence, is usually assumed.

My thinking is that it simply used the information based on observed cubs
to do so.

Hopefully, clearer.

Best,
