Replansky and Bell [22], in a long-term experiment, showed that both environmental complexity (i.e. the number of carbon substrates) and species richness tended to increase productivity of yeast communities, and that overyielding was mostly caused by resource partitioning.
Perhaps the most drastic changes in resource availability are caused by resource pulses.
Ecological character displacement is observed in Galapagos finches [ 2- 4], plethodontid salamanders [ 5], sticklebacks [ 2], Anolis lizards [ 6], and spadefoot toads [ 7, 8], and is generally believed to be caused by resource competition.
