Palaeoecology and evolution of marine hard substrate communities
Abstract Marine organisms have occupied hard substrates since the Archaean. Shells, rocks, wood and sedimentary hardgrounds offer relatively stable habitats compared to unconsolidated sediments, butExpand
The Permian of Timor: stratigraphy, palaeontology and palaeogeography
The Permian of Timor in the Lesser Sunda Islands has attracted the attention of palaeontologists since the middle of the nineteenth century because of the richness, diversity and excellent state ofExpand
Miocene glaciomarine sedimentation in the northern Antarctic Peninsula region: the stratigraphy and sedimentology of the Hobbs Glacier Formation, James Ross Island
The onshore record of Cenozoic glaciation in the Antarctic Peninsula region is limited to a number of isolated localities on Alexander Island, the South Shetland Islands and in the James Ross IslandExpand
A molecular phylogeny of bryozoans.
The authors' multi-gene analysis provides a largely stable topology across the phylum and discusses the extent of non-bryozoan contaminant sequences deposited in GenBank and their impact on the reconstruction of metazoan phylogenies and those of bryozoa interrelationships. Expand
Pliocene climate and seasonality in North Atlantic shelf seas
Fossil assemblages and stable isotope data demonstrate northwards extension of subtropical faunas along the coast of the Carolinas–Virginia relative to the present day, suggesting a more vigorous Florida Current, with reduced seasonality and warm water extending north of Cape Hatteras, and supports conceptual models of increased meridional heat transport for the Pliocene.

The identity of the invasive fouling bryozoan Watersipora subtorquata (d'Orbigny) and some other congeneric species.
A redescription of d'Orbigny's type of Cellepora subtorquata is provided, and two new species are described, Watersipora mawatarii n. Expand
The Cretaceous-Tertiary biotic transition
Mass extinctions are recognized through the study of fossil groups across event horizons, and from analyses of long-term trends in taxonomic richness and diversity. Both approaches have inherentExpand
Skeletal alterations and polymorphism in a Mediterranean bryozoan at natural CO2 vents
Colonies of the cheilostome bryozoan Schizoporella errata were grown at a site near Ischia Island where volcanogenic CO2 emissions lower seawater pH to 7.76, simulating levels of ocean acidification predicted for the end of the present century, corroborate previous studies demonstrating potential dissolution of carbonate skeletons in low pH seawater and provide new insight into the possible ability of colonial species to respond to ocean acidifying by adjusting resource allocation.

Evolutionary palaeoecology of symbioses between bryozoans and hermit crabs
Modern hermit crabs form associations with many organisms which encrust, bore into, or cohabit the living chambers of gastropod shells occupied by the crabs. Among these hermit crab symbionts areExpand
Skeletal ultrastructure and phylogeny of cyclostome bryozoans
This first, preliminary analysis implies that Rectangulata and Cancellata are monophyletic groups, whereas Articulata are diphyletic, and both Tubuliporina and Cerioporina paraphyletic. Expand
