Morphometric approaches to systematics and microevolution: Applications from paleozoic bryozoa
… fossil group. The combination of cryptostome bryozoans, revised taxonomic procedures, multivariate morphometric methods, and advances in microcomputer technology allows for research of this nature.

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

Taxonomy, Functional Morphology and Paleoecology of the Fenestellidae and Polyporiidae (Fenestelloidea, Bryozoa) of the Warsaw Formation (Valmeyeran, Mississippian) of the Mississippi Valley
Fenestellid and polyporid Bryozoa of the Lower Mississippian Warsaw Formation of the Mississippi River outcrop belt are represented by nine genera of Fenestellidae (three of which are new--Banastella, Cubifenestella, and Apertostella) and two genera of Polyporidae. Twenty-two previously described …

Cretaceous bryozoan fossils from Needs Camp, South Africa
Fossil Bryozoa in South Africa is understudied and has received little attention, despite the country's very rich geological and fossil heritage conservation. Published literature regarding bryozoan fossils from South Africa comprise of four papers with the most recent being a little over two …

Identification et distribution spatio-temporelle des épibiontes retrouvés sur l'exosquelette du crabe des neiges (chionoecetes opilio) dans le sud du Golfe du Saint-Laurent et sur le Plateau Néo-écossais
… Dans l'ensemble, les hydrozoaires, les bryozoaires, les polychètes et les balanes du gland représentent les salissures les plus fréquemment observées. Plus de vingt familles taxonomiques ont été identifiées, dont quatre considérées comme des taxons majeurs (≥ 50 % de l'occurrence). Les …

A study of marine fouling in Monterey harbor
… in Monterey Harbor were found to be barnacles, bryozoa, serpulids and hydrolds. The number of barnacles attaching to test palllets reached a peak in early April and then dectlned. The amount of fouling on the test panels increased with depth. Wood was determined to be the best surface for …

Molecular phylogenetics of the Metazoan clade Lophotrochozoa
… 4 investigates the Hox gene complement of the bryozoan Bugula turrita. Six Hox genes were recovered, including an ortholog of the posterior class gene Post2, which is a synapomorphy for the Lophotrochozoa. The identification of a Post2 ortholog provides evidence of a close relationship between …

The palaeoenvironments and stratigraphy of the Lincolnshire Limestone Formation (Middle Jurassic: Bajocian) of Northamptonshire and southern Lincolnshire
… by gastropods (but associated with bivalves, bryozoa, rare brachiopods and fragmentary echinoderms) has been recorded from several horizons within the complex stratigraphy sampled at Cowthick, three horizons at Clipsham, three of eight samples at Copper Hill, but is not known from Brauncewell. …

Palaeoecology and taxonomy of the macrobenthic fauna from the Upper Cretaceous Ajlun Group, southern Jordan
… 9 echinoids, and 4 corals. The phyla Porifera, Bryozoa, and Brachiopoda are represented by 1 species each. Additionally, at least two species of decapod crustaceans were found. One bivalve species is new: Anthonya jordanica from Cenomanian claystones of the eastern study area. 41 quantitative …

Bioinvasões marinhas do Brasil : composição, detecção e monitoramento de briozoários em substratos artificiais
… exótica e invasora marinhas, destaca-se o Filo Bryozoa. Os briozoários são indivíduos com intenso recrutamento larval, crescimento colonial rápido e com grande tolerância à variações ambientais, o que torna o grupo um dos mais representativos da comunidade do fouling. Por isso, entender a …

Spatial distribution and diversity of soft-bottom benthic invertebrates from demersal trawl surveys off the coast of Namibia
… Chordata (2 species), Sipuncula (1 species) and Bryozoa (1 species). The diversity of benthic invertebrate taxa along Namibia's coast was found to increase in a south-to-north direction. High abundances of arthropods were observed in the northern region, whilst ascidians dominated the central …

Cladistic Analysis of the Paleozoic Bryozoan Families Monticuliporidae and Mesotrypidae
Two closely related families of Ordovician bryozoans, the Monticuliporidae and the Mesotrypidae, collectively contain 12 genera that have been reclassified repeatedly by various authors. Using published illustrations for the type specimens of each genus, character states for 267 morphological …
