A very dense population of Plumatella fungosa (Pall.) (Bryozoa Phylactolema) has been observed in a pond and its outlet, polluted by organic matter from sewers.These organisms play an prominent part in the process of water purification; they can absorb annually an average quantity of 113 kg Nitrogen/ha in the zones where the biomass of the colonies reaches 15,6 T/ha.There is moreover an obvious relation between the evolution of the biological quality of water, classified according to the… Expand
Bacterial feeding by the freshwater bryozoan Plumatella fungosa (Pallas, 1768).
TLDR
The present study demonstrates for the first time the capacity of a bryozoan to feed on bacteria and indicates the ecological role of bryozoans in water purification. Expand

Despite their common occurrence and potential ecological and economic impacts, freshwater bryozoans have received very little attention in scienctific research. These “moss animals” comprise aExpand
Freshwater bryozoans (Bryozoa) of Norway IV: Distribution and ecology of four species of Plumatella with notes on Hyalinella punctata
Bryozoans were investigated during field studies of 601 lakes and other surface water bodies throughout Norway from 1960 to 1978. The frequency of occurrence of Plumatella repens was evaluated inExpand
Phyla Ectoprocta and Entoprocta (Bryozoans)
TLDR
The Phylum Bryozoa is a diverse group of benthic, suspension feeding invertebrates occurring in both freshwater and marine habitats, which includes entoprocts, which have similar features but are now considered to belong in a separate phylum. Expand

Heavy metal and PCB contamination of Bryozoan colonies in the River Meuse (Belgium)
In the Meuse River (Liège area, Belgium), large amounts of three species of Bryozoans, Fredericella sultana (BLUM.), Plumatella emarginata ALL. and Plumatella fungosa (PALL.) occur. They cover 3 toExpand
Ecology and Evolution of Malacosporean-Bryozoan Interactions
TLDR
This chapter provides an overview of malacosporean-bryozoan interactions by discussing effects of parasitism on host fitness and strategies of host exploitation through virulent overt and avirulent covert infections. Expand
Rate and process of tube production by the deep-sea hydrothermal vent tubeworm Riftia pachyptila
TLDR
The presence of clumps of freshly secreted tube material at the base of the exoskeleton as well as the new observation of bifid tubes allow us to propose a model of tube growth at both ends, which shows a variation of the gross morphology of the plume and the trunk of R. pachyptlla during growth and indicates that vestlmentum length and tube diamctrr could be useful indices of lndlv~dual and tube sizes.
