Abstract
The demise of the American bison, Bison bison (L.), following European settlement has given rise to two hypotheses regarding the fate of their dung-associated insects. The “extant” hypothesis proposes that all of these taxa now persist in the dung of cattle, Bos taurus L. The “extinction” hypothesis proposes that a subset of these taxa were unable to make this transition and have gone extinct. We examined these hypotheses by comparing the response of coprophilous insects to dung of bison versus cattle on similar diets and versus dung of cattle on different diets. Results showed insects to be more responsive to changes in diet than to changes in host species and, therefore, were supportive of the extant hypothesis. To our knowledge, these data provide the first experimental comparisons of bison dung versus cattle dung as habitat for coprophilous insects.

French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada.
