Free-living nematodes in seasonal coastal ice of the White Sea. Description of

Tschesunov A.V., Portnova D.A.

The taxonomical descriptions of three ice-living nematode species are given. They were found in the White Sea (northern Russia) for the first time. These species dwell on the underside and within understratum of the coastal ice. The ice appears in November and melts entirely to the end of May.

Interrelationships between copepods (Copepoda, Calanoida) of the White and Barents Seas and mechanisms of the independence of the White Sea population

Pertsova N.M., Pantyulin A.N.

Interrelationships between the pelagic fauna of the White and Barents seas were studied on the basis of populations of dominant planktonic copepods inhabiting both seas. The analysis of distribution patterns and life cycles and environmental conditions in the White Sea allowed one to distinguish different types of populations with respect to an exchange of individuals between two neighboring seas. The White Sea populations of

Mysids (Crustacea, Mysidacea) collected by Soviet and Russian Antarctic expeditions. Lophogastrida, Petalophthalmida, and Mysida: Boreomysidae

Petryashev V.V.

A large collection of mysids (392 samplings containing 3150 specimens) was made as a result of thirty-three Russian Antarctic Expeditions (since 1956) in the Antarctic and Subantarctic. The collection included six species of the suborder Lophogastrida out of eight ones inhabiting the region; two species of the suborder Pe-talophthalmida out of four ones, and five species of the family Boreomysidae (the suborder Mysida) out of nine species that dwell in this area. The new data on the geographical and bathymetric distribution of the mysid species are presented. A key for the identification of all species of lophogastrids, petalophthalmids, and boreomysids inhabiting the study region is given. Biogeographical and bathymetric characteristics are represented for each species.

Reed warbler,

Mukhin A.L., Chernetsov N.S., Kishkinev D.A.

A response of sylviids, primarily of reed warblers, to the playback of specific songs in some passerines was studied. The birds that stopped flying were mist-nettled at a specially designed field station. The distribution of birds that were captured at night and dawn during the presentation of different acoustic stimuli is discussed. The reed warbler song attracted the highest number of migrants, both reed warblers themselves and other birds dwelling in wetlands. The possible reasons for responses of nocturnally flying birds to acoustic stimuli and the role of specific songs during the selection of a site for a migratory stopover are discussed.
