Population Growth

Maximum sustainable yield is achieved at:

In the ideal logistic model, maximum sustainable yield occurs at K/2 because natural population production dN/dt is greatest there. Harvesting approximately that surplus could, in theory, maintain abundance while removing the largest annual increment. Real management is less certain because K and r vary, populations have age structure, and measurement error can turn a theoretical maximum into overharvest. Logistic predictions depend on assumptions that managers should not overlook. Carrying capacity changes with habitat and climate, and removing individuals may alter age structure, social orga

Population Ecology

For a population with r = 0.15 and K = 20,000, maximum sustainable yield is:

“1500” for for a population with r = 0.15 and k = 20,000, maximum sustainable yield is. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Population ecology links individual births, deaths, immigration, and emigration to changes in abundance. Per-capita rates determine the direction of change, while density dependence creates feedback when crowding alters survival or reproduction. The remaining alternatives—“450”, “3000”, “6000”—refer to different states, processes, or scales and therefore do not ex
