WebBritannica Quiz. Biology Bonanza. Population growth in K -selected species behaves according to the logistic growth equation: In this equation N is the number of individuals in the population, t is time, and r is the biotic potential. Examples of K -selected species include birds, larger mammals (such as elephants, horses, and primates ), and ... WebWe define seed limitation to be an increase in population size following seed addition. Here, we briefly consider how theoretical models deal with seed limitation and how seed sowing experiments can be used to unravel the extent of seed limitation in natural systems. We review two types of seed addition experiments: seed augmentation studies where seeds …
