Tend to have periods of growth that approach their maximum biotic potential
Usually short maturation times and short lifespans, therefore short generation times (reproduce at an early age)
Many offspring produced per reproductive event but
Often the number of reproductive events is limited to one or a few
Mortality (death) of offspring is often great
The above features are correlated with small size
These species often take advantage of short-term ecological opportunities (e.g., disturbances)
Examples include garden weeds, desert annuals, many insects
Species characterized by high reproduction rates, rapid development, early reproduction, small body size, and uncertain adult survival. Read more: http://www.answers.com/topic/opportunistic-species...
