Bryozoan colonial growth forms as paleoenvironmental indicators: evaluation of methodology and predictive utility 1997 1633 Bryozoans have played a significant ecological role in many shallow marine benthic communities since the Ordovician and are important contributors to carbonate sediment production in many modern cool-water marine environments. Correlation between bry...
Complexity Generated by Iteration of Hierarchical Modules in Bryozoa 2003 791 Growth in colonial organisms by iteration of modules inherently provides for an increase in available morpho-ecospace relative to their solitary relatives. Therefore, the interpretation of the functional or evolutionary significance of complexity wit...
Cool-Water Carbonate Production from Epizoic Bryozoans on Ephemeral Substrates 2000 1365 Bryozoan skeletons are a dominant constituent of cool-water carbonate sediments in the Cenozoic of southern Australia. The primary substrate on much of the modern continental shelf is loose sediment that is reworked intermittently to 200+ m water dep...
Paleoenvironmental Significance of Celleporaria (Bryozoa) from Modern and Tertiary Cool-water Carbonates of Southern Australia 2003 2170 Certain members of the bryozoan genus Celleporaria form large, erect colonies of hollow branches ( 10–30 cm tall and 1–3 cm diameter). These are common and conspicuous in Pleistocene and Cenozoic neritic strata of the southern margin of Australia. Mo...
Threshold Effects of Food Concentration on the Skeletal Morphology of the Bryozoan Electra Pilosa (Linnaeus, 1767) 2009 1035 Many palaeontological studies rely heavily on characteristics of the preserved phenotype, i.e. the morphology of skeletal hard parts. Although the potential for environmental influences on the phenotype is expected, rarely is the magnitude of the eff...
