Interpreting a Population Change Through Community Interactions, Worked

The idea
This procedure interprets an observed population decline by testing it against this chapter's growth, competition, predation, and succession mechanisms in turn, drawing together this chapter's population- and community-level atoms.
Where people slip
Assuming a decline must indicate predation or disease is the error here — density-dependent competition and successional replacement, per Bio 3591 and Bio 3609, produce the identical symptom without any predator or pathogen involved.
