“…The record of T . horrida at a southern coastal canal site is consistent with the species' distribution in warm, brackish water (Poirrier, ; Sharapova, Trylis, Ivanov, & Ilyushina, ), its presence in navigable canals (Schletterer & Eggers, ), and rarity (Gugel, ; Richelle‐Maurer, Degoudenne, Vyver, & Dejonghe, ). With no previous UK records of any Trochospongilla taxa, we might speculate that T .…”

Freshwater sponges are important to ecosystem functioning; however, information about their biogeography and interspecific variation is fragmentary, limiting our ability to assess their role. Although the specific epithets of two common species suggest that sponges found in lentic habitats are Spongilla lacustris, and those found in lotic habitats are Ephydatia fluviatilis, the number of sponge species in the UK is unresolved. We sampled sponges in a variety of habitats and used both morphological and molecular (D3 domain of 28S rDNA) methods to identify six species, including the first record of Trochospongilla horrida. We contrasted species in terms of their environmental tolerances, habitats, and variation, and we expanded on the limited information available about the geographic distributions of these sponges. In our study, most sponge species colonized a variety of substrates, but exhibited different distributions. The most widespread sponge, S. lacustris, was present at lower mean water temperatures and was more often located above a latitude of 55°N. Ephydatia fluviatilis was the most common species in rivers, but was also located in lentic habitats. Salinity in anthropogenic habitats was not a significant factor for the presence of E. fluviatilis or the more patchily distributed species Eunapius fragilis. Instead, these species occurred more frequently at sites with negative oxidation–reduction potential. Sponge biodiversity may be affected by substrate availability in anthropogenic habitats, invasive species, and improved ability to recognize sponge taxa. Crucially, we provide foundation data as a prerequisite for future ecological evaluation.

“…Their largest number (from 10 to 25%), as expected, is concentrated in the lake sapropel. The Demospongia class in the continental reservoirs of Western Siberia predominantly represents sponges; freshwater bodyagy and several other species are ordinary for modern ecosystems, (Sharapova et al 2014). Remains of the sponges skeleton are often found during paleobotanical investigations the archaeological sites of Western Siberia located in floodplains of rivers and lakes (Sharapova et al 2014).…”

The article presents the analysis of the microbiomorphic soil profile of the swampy meadow. Phytoliths, spicules of sponges and Rhizopoda shells are abundant in the soil. There are spores of fungus and mosses, as well as zoogenic material. The change in the natural conditions of the object during the second half of the holocene was reconstructed based on the obtained data. Differences in the content of microbiomorphs in different horizons of the soil profile of the swampy meadow correspond to the general regional and local processes of climate and vegetation dynamics in Northern Kulunda and adjacent territories.

“…Gemmules form mainly in the autumn as a means of survival during the freezing season. In Western Siberia, gemmule-producing sponges are distributed mostly in the steppe-forest zone and southern taiga [46], but S. lacustris also occurs in the foresttundra transition zone and was found in one locality within the southern tundra. S. lacustris can grow on a pond bottom or be attached to aquatic macrophytes [47].…”

We present the first record of Holocene fossil insect assemblages from Central Yakutia. A stratigraphic sequence in the locality within the Vilyuy River valley is a buried oxbow. The late Holocene water body inherited an impervious stratum from the late Pleistocene. The organic layer preserved rich fossil assemblages of macrofossils including insects and other invertebrates, plants, and charcoal. The ancient flora and fauna include species that are common in Yakutia as well as those that are rare and absent in the region. The most abundant finds are leech cocoons and bogbean seeds. The macrofossils of some insects were found along with remains of their host plants. Despite the absence of intensive human land use in the area, traces of fires were recorded. The oxbow represents the environment of a floodplain wetland that developed separately from the ecosystem of the adjacent sand dunes.
