OBJECTIVE FORESTRY

Detailed explanation-1: -Boom-and-Bust cycles occur when the population growth of one species is closely tied to a limiting factor that may be expended. The predator populations increase and decrease as the prey numbers change. Predation may be an important cause of density-dependent mortality for some prey.

Detailed explanation-2: -What are boom and bust cycles? The boom and bust cycle applies to many populations like insects, birds, and mammals. The boom is when the population grows exponentially rapidly, it is then followed by a bust, which is when the population falls back to a minimal level. Boom and bust cycles are like rollercoasters.

Detailed explanation-3: -Fishes that form large aggregations are particularly susceptible to over-harvesting, and many deep-water fisheries go through a “boom and bust” cycle in which landings from newly-discovered fisheries are initially high, then rapidly decline to very low levels.

Detailed explanation-4: -Why does it make sense that predator-prey species relationships follow boom and bust cycles? Because prey gets eaten the predator population increase and while the prey population decreases.
