In contrast, species in stable communities with density dependence were expected to display traits associated with strong competitive a

However, the types of evolutionary processes that produce life histories that are optimal in some sense can only be determined from genetic models of selection in

https://doi.org/10.1007/978-3-642-94649-3. Individual organisms may adjust physiologically to the entire range of conditions. Populations may systematically change in gene frequencies (where the environmental variation is sufficiently predictable). Likewise, both physiological and genetic changes may occur in space and time.

Also, the seasonal occurrence of vulnerable stages must be timed to avoid periods of physical extremes and periods when parasites, predators, and competitors occur at high densities. In a seasonal

Whether or not one accepts this account literally, one can still legitimately ask the question: Why is this account of a virgin birth contained in Matthew? Most peopl

Attempts to evaluate the importance of variation, either in the production of heterosis or as adaptive polymorphisms in homogeneous, heterogeneous, or fluctuating environments, are generally confounded by two major problems: (1) identifying the forces of s
