Energy availability has long been recognized as a predictor of community structure, but causal relationships between energy availability and community structure remain unclear. One challenge is that determinants of available energy in natural systems are diverse and often unidentifiable. Multiple, functionally distinct sources of energy exist in terrestrial, freshwater, and coastal marine systems, and energy from these sources flows across landscapes and habitat boundaries. Another challenge is that “community structure” consists of three components—standing stock, trophic structure, and diversity—and energy availability does not consistently predict any one component. Understanding processes underlying patterns of community structure requires identifying tradeoffs between standing stock, trophic structure and diversity, yet such studies are rarely done. Wood-fall communities in the deep sea are an ideal test system for many theories about community assembly and energetic theory for three reasons. First, the amount of energy available to the community can be precisely manipulated in the form of wood mass. Second, flows of energy from wood through the community can be easily tracked because animals supported by wood are isotopically distinct from other animals in the background benthos. Finally, the entire community associated with a wood fall can be sampled, allowing for accurate estimates of standing stock. For these reasons, deep-sea wood falls make possible accurate joint analysis of standing stock, trophic structure, and diversity as a function of energy availability. I will discuss and identify the tradeoffs in energetic processes that regulate the biodiversity and structure of communities, using ROV/submersible-deployed wood falls. ]]>

He has conducted oceanographic research for 18 years and published over 50 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, metabolism, and energy flow focusing often on the deep sea. His works seeks to uncover and explain general patterns and processes in ecology and evolution and identify promising mo. http://craigmcclain.com https://cdn.slidesharecdn.com/ss_thumbnails/mcclainwoodfallwmbc2018-180513202452-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/energy-availability-metabolic-niche-dynamics-and-connectivity-alter-assembly-rules-in-deepsea-wood-falls/96960138 Energy availability, m... https://cdn.slidesharecdn.com/ss_thumbnails/metabolicniche-160207162015-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/how-metabolic-niches-shape-marine-life/57977294 How Metabolic Niches S... https://cdn.slidesharecdn.com/ss_thumbnails/mcclaintwitter-151104193511-lva1-app6892-thumbnail.jpg?width=320&height=320&fit=bounds slideshow/a-scientists-view-of-twitter/54749131 A Scientist's View of ...
