An apparent paradox exists in the ecology of Antarctic lichens: their net photosynthetic temperature optimum (around 0°C) lies far below the temperature optima of their constituent algae and fungi (around 20°C). To address this paradox, we consider lichens as microbial communities and propose the “community adaptation” hypothesis, which posits that in each thermal regime there is an equilibrium between photosynthetic primary producers (photobionts), and heterotrophic consumers (mycobiont and… CONTINUE READING
