  • Imagine taking a college class or becoming an undergraduate major in predatorology or primary producerology. Most of us would think this rather ludicrous because we generally do not consider the means by which organisms garner resources as sufficiently fundamental to define a subdiscipline of biology. But somehow parasites have been considered odd enough in their mode of foraging to justify singling them out for considerable special attention. Parasitology is one of the oldest distinct branches of biology, having evolved as an unusually interdisciplinary combination of autecology, physiology, developmental biology, functional morphology, systematics, ethology, and immunology. But as modern biology has restructured around levels of organization (cellular and molecular, organismal, and community and ecosystem), the appropriate place for parasitology has become unclear. Although we have no rigorous data to test our impression, it appears to us that college classes and majors in parasitology have waned dramatically in recent decades. Paradoxically, though, the demise of parasitology has been accompanied by increasing attention to the biology of parasites.
