В работе представлены данные многолетних исследований фитопланктона и микрофитобентоса реки Черной (Выборгский район), а также гидрохимического состава воды гранулометрического грунта. Видовое богатство выше, чем микрофитобентоса. обоих сообществах преобладали диатомовые водоросли, видом–доминантом являлась Aulacoseira subarctica (O. Müller) E.Y. Haworth. Сезонные изменения обилия имели типичный для водоемов северо-запада России характер. The paper presents the data on long-term studies of...

The presence of larvae the European river lamprey Lampetra fluviatilis was reported for first time from in macrobenthic communities Neva Bay Gulf Finland (St. Petersburg, Russia). It has been shown that ammocoetes inhabit several areas, at depths to 12 meters. Apart ammocoetes, with contain abundant oligochaetes, bivalves, and less commonly chironomid larvae. At some sites, number up 80 specimens/m2, while their biomass over 90% total community. abundance macrozoobenthos these sites is...

Abstract Small freshwater (resident) populations of the European river lamprey Lampetra fluviatilis from an isolated sea upper part a system with numerous lakes (the reaches tributaries Daugava River and Lake Peipus, Pskov Oblast, Russia) have been studied. Adult individuals attributed to common large size groups; adults are similar other resident Baltic Sea basin. The presence larvae different age groups indicates regular spawning in studied watersheds. Analysis modern historical (before...

Colonies of the freshwater bryozoan Pectinatella magnifica (Leidy, 1851) were found in north-west Russia for first time.As colonies have been observed Vuoksi river connecting Saimaa and Ladoga lakes, most likely this is a result downstream migration from Finland.Details general morphology P. distribution sensory structures on lophophore colony surface studied using scanning electron microscopy.Three types recorded.Two rows presumably immobile cilia latero-frontal surfaces tentacles, type...
