In order to understand the nature of the ecologist ' s investigation ， we may think of the density - dependent effects on growth parameters as the “ signal ” ecologists are trying to isolate andinterpret ， one that tends to make the population increase from relatively low values or decrease from relatively high ones ， while the density - independent effects act to produce “ noise ” in the population dynamics 為了能理解生態學家們所從事的研究的性質，我們可以把那些作用于增長參數的密度依賴效應視作生態學家們力圖將其分離并予以解釋的“信號” ，正是這一信號傾向于使種群從相對較低的數值遞增，或從相對較高的數值遞減；而與此同時，那些密度獨立效應起到的作用則構成了種群動態變化中的“噪音” 。 |
