Presentation Title: The role of temperature on food web dynamics and ecosystem functioning of streams along a natural temperature gradient

Abstract: Rising temperatures are altering the patterns and processes of Earth's ecosystems with potentially large consequences for the services they provide. The effects of temperature on biological systems are difficult to predict, especially at higher levels of organization such as communities and food webs where complex networks of interactions shape biological responses. Yet, identifying the responses of communities and food webs to temperature represents a critical bottleneck in our understanding of the effects of climate warming. In this talk, I will present patterns of food web dynamics and ecosystem function within a 'natural laboratory' of streams spanning a 25 C temperature gradient throughout a single watershed in Iceland. I will discuss the direct and indirect influences of temperature on consumer community energy demands throughout the year, the importance of food availability in shaping these demands, and how this interplay modifies the temporal stability of consumer-resource interactions.
