Consequences of competition on the time budgets, growth and distributions of three species of terrestrial slugs

Summary The behavioural time budgets of two non‐aggressive slugs and one aggreessive species were evaluated in monocultures or in 2‐way combinations in field cages. The seasonal time budgets of L. maximus, A. ater and A. columbianus in monoculture were remarkably similar despite their strong differences in physiological resource allocation. Similarity in physical design and resource utilization appeared to be more important determinants of …
