This study provides field evidence in support of the
“parasite spillback hypothesis” that predicts a positive numerical
response of native parasites to the presence of an exotic
host that is competing for these parasites with native hosts.We
examined the role that the exotic mollusc Dreissena polymorpha
(zebra mussel) plays as the second intermediate host
of the echinostomatid trematode Echinoparyphium recurvatum
in Lake Naroch, Belarus. We found that due likely to the
disproportionately high abundance of its novel exotic host,
the metacercarial stage of this parasite has become substantially
more abundant than that of other echinostomatid
trematodes recorded in native molluscs. This finding suggests
an increased load (the “spillback”) of E. recurvatum on native
waterfowl that serve as its final hosts. The risk of aquatic
birds becoming infected with this trematode via feeding on D.
polymorpha was found to vary both spatially and seasonally.
This risk was particularly high in the autumn at a depth of
2 m and at sites of bird gatherings.

The paper includes data on species composition of chironomid larvae which were encountered in
the mantle cavity of zebra mussels (Dreissena polymorpha) within 7 waterbodies in the Republic of
Belarus. All were found to be free-living species commonly present in periphyton and/or benthos.
A long-term study of the seasonal dynamics of these larvae in Dreissena did not reveal any typical
pattern. Our data suppose that chironomids do not have an obligate association with zebra mussels and
possibly enter their mantle cavity inadvertently.

BIOLOGICAL FILTERS ARE AN IMPORTANT PART
OF THE BIOSPHERE
S.A.Ostroumov
Abstract: Studies of ecology of living organisms lead to a more profound understanding of the intricate processes of the Earth’s biosphere functioning. The mankind is still far from establishing harmonious relations with it. However, permanently progressing destruction of natural complexes by the technogenic civilization necessitates some new revolutionary approaches to their preservation. That is why it is so important to study the relationships and interactions between living organisms. One of the most important roles in this “orchestra” is played by numerous invertebrates which filter the water and improve water quality.
