  15. Morphometric Approaches to Analysis of Microevolution: Morphologic Variation in Paleozoic Bryozoa

    Holdener, Eric JamesUniversity of Illinois at Urbana-Champaign2015

    Temporal variation is recognized among stratigraphically separated populations. Colonies become more gracile through time, but populations are not ecotypes tracking favorable environmental conditions. Characters describing zooidal living chambers contribute more to the discrimination of populations …
