A bibliography of "Dreissena polymorpha in European and Russian waters: 1964-1993"

A bibliography of over 1000 papers on the biology, impacts, and control of the zebra mussel (Dreissena polymorpha) in European and Russian waters is compiled to aid scientists and managers in addressing this species of economic and ecological importance. The bibliography primarily includes publications between the early 1960s and early 1990s but does contain some earlier references not found in another extensive bibliography published in 1964. This bibliography will be a valuable tool, especially to water users and environmental scientists in North America where zebra mussels have recently invaded and become established.

Redefinition of Teneridrilus Holmquist (Oligochaeta: Tubificidae), with description of two new species from North America

The tubificid genus Teneridrilus Holmquist, 1985 (subfamily Tubificinae) is redefined. The genus was originally monotypic for the type species, formerly classified as Ilyodrilus mastix Brinkhurst, 1978. The genus now includes Teneridrilus columbiensis, a new combination for Isochaetides columbiensis, and two new species. The first of these, Teneridrilus calvus, is described by Erseus and Brinkhurst, and the second, Teneridrilus flexus, by Erseus and Hiltunen. Synapomorphies for the genus are strongly modified chaetae in II and an enlarged eversible pharnyx. The genus is distributed from China to British Columbia, Washington and California in freshwater near the mouths of large rivers, and in the St. Marys River, which connects Lake Superior with Lakes Michgan and Huron.
