Analysis of ambient and exhalant water samples collected in situ indicates that the net POC diet of three tropical Demospongiae, Mycale sp. Expand
Water transport, respiration and energetics of three tropical marine sponges
The rates of water transport and respiration of three tropical marine demosponges Mycale sp., Tethya crypta (de Laubenfels), and Verongia gigantea (Hyatt), have been determined in natural fieldExpand
In situ pumping activities of tropical Demospongiae
Studies employing Scuba techniques were carried out on populations of 3 species of tropical demosponges to determine in situ patterns of water-pumping activity, finding that constant activity may be restricted to thin-walled species working at low pressures and velocities. Expand
Partial Carbon and Energy Budgets of the Bacteriosponge Verohgia fistularis (Porifera: Demospongiae) in Barbados
The nutrient resource spectrum of Verongia fistularis and other bacteriosponges appears to be overwhelmingly dominated by dissolved organic matter, and thus contrasts strikingly with the present knowledge of nutrition in the normal non-bacteriosponge sponges. Expand
The biology of glass sponges.
This chapter is the first comprehensive modern account of hexactinellid ecology, including an account of habitats, distribution, abundance, growth, seasonal regression, predation, mortality, regeneration, recruitment and symbiotic associations with other organisms. Expand
The aquiferous systems of three marine demospongiae

The aquiferous systems of three common, coastal, marine Demospongiae, Halichondria panicea (Pallas), Haliclona permollis (Bowerbank) and Microciona Prolifera, are analyzed by measurements of cross‐sectional areas of conducting elements and the porocyte nature of the ostia is established for all three species.

Bacteria as food for temperate-water marine sponges
If bacterial toxins are produced by these sponges, their activity must be restricted to local sites within the confines of the organisms. Expand
In situ feeding and metabolism of glass sponges (Hexactinellida, Porifera) studied in a deep temperate fjord with a remotely operated submersible
Reported mean sponge abundances indicate that the sponge filtering activity may significantly affect the deep microbial community and benthic–pelagic mass exchange in some north– east Pacific fjords. Expand
Patterns of glass sponge (Porifera, Hexactinellida) distribution in coastal waters of British Columbia, Canada
Glass sponges are enigmatic members of the deep-sea fauna that inhabit shallow waters in only a few locations world-wide. In order to understand what factors influence the distribution of glassExpand
Taxonomy, distribution, and ecology of the freshwater bryozoans (Ectoprocta) of eastern Canada
The freshwater Bryozoa (Ectoprocta) are one of the most poorly known faunal groups in Canada and a recent survey of 80 freshwater habitats in eastern Canada revealed 14 species, representing 56% of described species in North America. Expand
