Abstract

Euphydryas chalcedona at Jasper Ridge consists of two independently varying major demographic units, similar in scale but not in structure to those of Euphydryas editha. In contrast, however, Jasper Ridge E. chalcedona represent just a portion of a deme-while E. editha occurs as two partially connected demes. The life history and general ecology of E. chalcedona is described and compared with those of its intensively-studied congener. Various problems of mark-release-recapture estimation of population size are discussed.
