Studies on the effects of temperature on the activities of Embden-Meyerhof (EM) glycolysi~ and the hexose monophosphate shunt (HMP) in fishes have dealt mainly with exotic and/or acclimated fishes. This study reports the effects of short-term reductions in temperature on EM and HMP activity in two closely related species of temperate fishes (Sebastes spp.) and its possible relation to the therm...

Imitators mimic the output decision of the most successful firms of the previous round a là Vega-Redondo (1997). Optimizers play myopic best response to the opponents’ previous output. The dynamics of the decision rules induce a Markov chain. As expression of bound...
