Species, Nutrients, and Macroevolution

My research is mainly focused on exploring the macroevolutionary effects of “trophic resources” in its various manifestations (food, nutrients, productivity), especially as these can be revealed and studied in the fossil record. How does taxonomic diversity relate to nutrient supply on geological timescales? What is the influence of nutrient supply on speciation? Turritelline gastropods appear to prefer high-productivity environments, and they have been at the center of much of my work in this area. But I am interested in these topics as applied to other taxa—from frogs to whales.
