“…Distribution of bryozoan growth forms is controlled by extrinsic factors (e.g., Stach, 1936;McKinney and Jackson, 1989;Smith, 1995;Hageman et al, 1997Hageman et al, , 1998Amini et al, 2004). Therefore, an analysis of bryozoan growth forms in a palaeocommunity may reveal import insights in the palaeoenvironment.…”

“…Cyclotrypa alexanderi encrusting/branched McKinney and Jackson, 1989;Amini et al, 2004). Reticulate colonies may occur in a variety of hydrodynamic conditions (e.g., Stach, 1936;Pedley, 1976, Cuffey andMcKinney, 1982), whereas erect branched colonies (especially the robust ones) are considered vulnerable to damage in high energy conditions (Cheetham and Thomsen, 1981).…”

The bryozoan assemblage from the Zhongba Formation of southwestern Tibet includes 30 species of 25 genera. Seven species are new: Fistulipora sakagamii n. sp., Dybowskiella hupehensiformis n. sp., Etherella tibetensis n. sp., Dyscritella lii n. sp., Streblotrypa (Streblotrypa) parviformis n. sp., Timanotrypa australis n. sp., and Protoretepora irregularis n. sp. One genus with one species is also new: Tibetiporella ornata n. gen. n. sp. The described fauna implies a Cisuralian (Artinskian-Kungurian) age of the Zhongba Formation and shows relationships to the Cisuralian faunas of Thailand, Western Australia, Oman, Timor, central Pamir, Iran, Urals, and other Tibetan localities. The bryozoan fauna from the Zhongba Formation shows an intermixture of both Boreal and Gondwana elements, and implies stronger faunal migrations into the tropical region from both the north and south. Palaeoecological analysis suggests that the Zhongba Formation was deposited in a middle shelf setting some distance from shoreline, probably influenced by local currents.

“…It has long been recognized that at the interspecific level, strong correlations exist between colony morphology and habitat characteristics such as sediment carbonate content and environmental energy (Stach 1936, Cheetham & Thomsen 1981, Nelson et al 1988, Hageman et al 1998, Amini et al 2004, providing a useful tool for interpreting present and past environments. There has been less research on intraspecific phenotypic variation in bryozoans.…”

“…Tidal currents that run through the South Bay can attain speeds of 3.5 knots on an outgoing or incoming tide and wind waves of up to 2 m can occur in the deep central channel of the South Bay, although wave heights decrease over the shallow mudflats where the bryoliths were found. Alternatively, bryoliths could be turned by animals such as crabs, rays and other fishes foraging or burrowing on the mudflats.Whatever its cause, this unique morphology may aid this species in spreading throughout the bay in 2 ways: (1) the spheroidal colony shape may allow this organism to disperse with wind and wave currents, and (2) fragments which escape burial should be able to form new colonies.It has long been recognized that at the interspecific level, strong correlations exist between colony morphology and habitat characteristics such as sediment carbonate content and environmental energy (Stach 1936, Cheetham & Thomsen 1981, Nelson et al 1988, Hageman et al 1998, Amini et al 2004, providing a useful tool for interpreting present and past environments.

A non-native bryozoan creates novel substrate on the mudflats in San Francisco Bay

A non-native bryozoan, Schizoporella errata, forms extensive patches of free-living balls and reef-like structures (bryoliths) on the mudflats in south San Francisco Bay, California. The ball-like bryoliths range from 2 to 20 cm in diameter, and the reef-like structures can be nearly 1 m across. While S. errata is known to form bryoliths in other locations, free-living aggregations like these have not been reported. Colony morphology appears to be a plastic trait as analysis of relationships among forms using cytochrome oxidase subunit I (COI) nucleotide sequence data revealed no genetic separation. We recorded > 50 species of algae and invertebrates living on and in the bryoliths and determined the invasion status for 34 of the 50 species. Of the 34, 25 (74%) were non-natives and included fouling species that require hard substrate. The bryoliths may thus facilitate colonization by invaders on the mudflats and serve as stepping stones between the limited hard substrate habitats in the Bay.

J. Zabin pers. obs.).Non-native marine species that create 3-dimensional structures in soft-bottom habitats can also have significant ecological impacts, facilitating the presence of obligate hard-substrate organisms, creating living space for other organisms, and in some cases altering the quality of the nearby benthos (e.g. Posey 1988, Ricciardi et al. 1997, Crooks & Khim 1999, Bruno et al. 2005, Rodriguez 2006. In a literature review, Bruno et al. (2005) found that non-native species facilitated the presence of native species at least as often as that of other non-native species. However, it might be reasoned that when a non-native species creates a novel substrate type, other non-natives may be more likely than natives to either (1) be pre-adapted to use the new substrate or (2) display the environmental plasticity to do so. For example, Heiman et al. (2008) found that reefs created by the Australian tubeworm Ficopomatus enigmaticus in a predominantly soft-bottom estuary in Central California supported abundant communities of non-native amphipods and polychaetes. Native species associated with native oysters also inhabited the worm reefs, but non-native species were much more abundant in the tubeworm reefs than on oysters, suggesting differential facilitation of non-native species by this new foundation species (Heiman et al. 2008).In 2006, we became aware of another organism typically thought of as hard-substrate dependent, living as an unattached form on the mudflats in San Francisco Bay, California. Spheroidal colonies of a bryozoan, ranging from golf ball to football size (~2 to 20 cm), were found in large numbers in the shallow subt...
