What reproductive strategy is driven by unpredictable environments characterized by high mortality risks or short reproductive windows?

Answer

Rapid maturation and semelparity

Boom-and-bust cycles or high mortality risks create urgency, selecting for life histories that ensure genes are passed on quickly through rapid maturation and reproducing only once before death, if necessary.
