Investigating Causal Relationships between Global Change and Insect Interaction Networks: Insights into Dietary Specialization, Interaction Diversity, and Disturbances
… effects of biotic and abiotic gradients on dietary specialization, interaction diversity, and related attributes of arthropod communities. My focus on how specialization varies across gradients and is affected by global change addressed a classic hypothesis, the "jack-of-all-trades is a …

Evolution in biological radiations; insights from the Triassic archosaur radiation
… tooth assemblage from Tanzania to reconstruct dietary specialization, estimated by morphological disparity of teeth. In addition to comparing tooth disparity of isolated and in situ teeth, this also provides a lens for comparing the timing of dietary specialization and species diversification. …

Seabird digestive physiology in relation to foraging ecology
… opportunists or specialists? The extent of specialization in seabird digestive processes to different diets and foraging methods, is investigated experimentally. Gut passage rates of different food types of tested in vitro digestibility may reflect dietary specialization, with favoured prey …
