“…Brandtia parasitica has a spatial distribution that includes the entire shoreline of Lake Baikal, from 1.5 to 60 m depth, rarely down to 200 m. Its presence is strongly correlated with that of the Baikalean freshwater sponge, Lubomirskia baikalensis which it inhabits. Some researchers believe it is parasitic, feeding on the sponge's body tissues (Kamaltynov et al, 1993;Dembitsky et al, 1994), others think it is merely commensal with the sponge (Timoshkin, 2000;Mekhanikova, 2001). The other two amphipods have distributional characteristics close to that of B. parasitica.…”

Thermopreference reactions and avoidance sensitivity to dissolved oxygen levels were measured in three endemic amphipod species from Lake Baikal: Eulimnogammarus verrucosus and E. vittatus, as well as Brandtia parasitica, which is a symbiont of the Baikalean sponge, Lubomirskia baikalensis. The benthic E. vittatus and E. verrucosus demonstrated highly developed thermopreference reactions, whereas B. parasitica did not show thermopreference behaviour. The experimental results also showed that E. vittatus and E. verrucosus avoid water with decreased dissolved oxygen levels, whereas behavioural reactions of B. parasitica did not depend on oxygen concentration. In the presence of sponge fragments, individual B. parasitica moved actively towards them, and concentrated on those fragments. Possible reasons for reduction of behavioural preference in B. parasitica are discussed with a focus on the species' symbiotic status. RÉSUMÉLes réactions de préférences à la température et la sensibilité d'évitement par rapport aux niveaux d'oxygène dissous ont été mesurées chez trois espèces d'amphipodes endémiques du lac Baïkal: Eulimnogammarus verrucosus et E. vittatus, ainsi que Brandtia parasitica, qui est un symbiote de l'éponge endémique Lubomirskia baikalensis. Les espèces benthiques E. vittatus et E. verrucosus ont démontré des réactions de préférences à la température hautement développées, tandis que B. parasitica n'en montrait pas. Les résultats expérimentaux ont aussi montré que E. vittatus et E. verrucosus évitaient l'eau ayant des niveaux bas d'oxygène dissous, tandis que les réactions comportementales de B. parasitica ne dépendaient pas de la concentration en oxygène. En présence de fragments d'éponge, les individus de B. parasitica se déplaçaient activement vers eux, et se concentraient sur ces fragments. Les possibles raisons de la réduction des préférences comportementales chez B. parasitica sont discutées avec une attention particulière au statut symbiotique de l'espèce.

“…All species studied are known to have seasonal migration activity. Kamaltynov et al (1993) described downward migrations of adult B. parasitica in the autumn, at a time when the winds increase. They believed the migrations serve as a mechanism to avoid wave action.…”

“…This term was introduced to biocenology by Beklemishev (1951) and Ramenskii (1952). Although the volume and content of the notion of consortia remain controversial (Arnol'di et al , 1969;Rabotnov, 1969Rabotnov, , 1973Rabotnov, , 1974Nosova, 1973;Voronov, 1974;Kamaltynov et al , 1993), we believe that it fits best for elementary biocenosis which includes interacting populations of the edificator and consort species. As for aquatic ecosystems, we consider the viewpoint of Kharchenko and Protasov (1981) as the most convincing.…”

A survey in the basin of the Khilok River (a right tributary of the Selenga River) in 1999-2002 allowed us to reveal and describe the consortia of cyanobacteria Stratonostoc linckia f. linckia and Stratonostoc verrucosum , green alga Cladophora aegagropila , stonewort Nitella opaca , water moss Fontinalis sp., and duckweed Lemna trisulca. The relationship between the consort organisms and edificator plants can become the limiting factor in these communities. The long-term studies of the benthic communities of the Arakhlei Lake demonstrate the significance of the consortium approach in the long-term prediction of changes in the lake ecosystem.

“…Interestingly, however, in a reference sponge sample from the River Pilica (of which the River Gac is a tributary), the same authors identified Marionina riparia. To the best of our knowledge, the only previous record of oligochaetes associated with lake-dwelling sponges included members of Naididae, Propappidae, Lumbriculidae and Tubificidae found on the basal surface and in cavities between the substrate and the base of Lubomirskia baicalensis (PALLAS, 1773) (Demospongiae: Haplosclerida: Spongillina: Lubomirskiidae), a shallow-water (4 -15 m) endemic of Lake Baikal (KAMALTYNOV et al, 1993).…”

The dissection of Heterorotula sponges collected in an area of geothermal activity at 126-145 m depth on the floor of Lake Taupo revealed a dense population of associated Enchytraeidae. They represent three species of Marionina, two of which known but exotic (the Palaearctic M. riparia BRETSCHER, 1899 and the Chinese M. seminuda XIE and ROTA, 2001), and one new to science, M. spongicola sp. n. This is the first report of an ecological association between enchytraeids and poriferans in the lake profundal zone. The possible nature of such relationship (casual contact for feeding or dwelling for food and shelter) is discussed.
