State
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.
Watch for
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.
