What is bet-hedging, really?
Jörgen Ripa, Helen Olofsson, Niclas Jonzén · Proceedings of the Royal Society B Biological Sciences · 2009
Bet-hedging is defined as a strategy that reduces the temporal variance in fitness at the expense of a lowered arithmetic mean fitness. After a few technical points, we will here argue that this definition of bet-hedging is badly suited for models with density- and/or frequency-dependent fitness. A strict interpretation cannot be employed; possibly, a modified definition is necessary.
