摘要: We classify habitat features based on their effects fish population dynamics and how populations affect the habitat's dynamics. term that can be reduced in quantity or quality by usage as consumable resources. In general, resources regulate a density-dependent manner. contrast, nonconsumable influence density-independent further have supply of resource. designate whose is unaffected (e.g., space) being dynamically unaffected. Thus, these does not depend present past abundance fish. The affected prey abundance) depends current abundance. Using lake whitefish (Coregonus clupeaformis ), we illustrate changes integrated with growth, survival, reproduction through stock-recruitment relationship. This example shows single measures response such carrying capacity surplus production do fully represent population-level following alteration.
