Abstract
Ranges of fossil taxa have received great attention in the context of biostratigraphy and of evolutionary studies dealing with species longevity, but relatively little in terms of community membership. Recently, however, recognition of residence-time components has produced results of interest for the dynamics of communities, and for the comparison of community change on ecological and evolutionary scales. Residents and transients, as used here, refer to taxa with long and, respectively, short membership times in fossil metacommunities over evolutionary timescales. The distinction of the two components is based on the durations over which rodent taxa occur in a composite Miocene section in a restricted area. Residence times allow calculation of community age (CA), defined as the mean of the residence times of the community members at locality age. CAs are negatively correlated with the numbers of members, due to preferential loss of transients while retaining residents during episodes of decreasing community richness.
