DescriptionThis dissertation provides a four-part synopsis of the methodology, results, and conclusions of an integrated set of experiments designed to explore the ecology of inducible trophic polymorphisms (ITPs). These experiments were conducted using isogenic populations of the polymorphic freshwater hymenostome ciliate, Tetrahymena vorax Kidder, in combination with other protozoa, bacteria, algae, and micro-invertebrates. Chapter 1 addresses the autecological significance of ITPs, revealing some of their potential costs and benefits to individuals in the context of competition under varying resource regimes. Chapter 2 demonstrates how ITPs can give rise to novel trait-mediated indirect interactions that affect community structure and population dynamics. Chapter 3 elucidates the extent to which the population dynamics of species exhibiting ITPs are affected by the trophic complexity of their habitat. Chapter 4 presents a detailed review of indirect offenses, a versatile adaptive strategy that ITPs can give rise to where inducing agents are symbionts. The contents of these chapters provide unique insights into the link between ITPs and related phenomena – such as cannibalism, intraguild predation, omnivory, and expanded diet breadth – and open new avenues of inquiry regarding the importance of the genetic and functional diversity of natural communities.
