“…As we reported earlier (Ganin et al 2014;Ganin & Atopkin 2018), the original habitats of this earthworm are within the Paleo-Amur River basin in the Late Neogene. About 12.5 million years ago, the spread of these drawidas from west to east could have been limited, as suggested by the reconstruction of the river network and ancient watersheds (modern ranges of the Maly Khingan Mts.…”

“…Nucleotide sequences were initially assembled with the SeqScape v.2.6 software and aligned using MEGA 6.0 alignment explorer with default options (Folmer et al 1994;Tamura et al 2011). Aligned COI gene fragments 581-650 bp long and GenBank data, including molecular data from earlier studies (Atopkin & Ganin 2015;Deca'ns et al, 2013;Ganin & Atopkin 2018) were used for calculation of variable and parsimony-informative sites, genetic p-distances and Neighbour-Joining and Maximum Liklihood phylogenetic reconstructions using MEGA 6.0. And the most appropriate model (AIC-Akaike information criterion) for ML analyses was also constructed by MEGA v.6.0.…”

“…Anisimov et al (2015) stated the chromosome number, DNA mass index and concluded that polyploidy as a species-or race-forming factor is not typical of these earthworms. Studies of mitochondrial COI gene fragment variations (Atopkin & Ganin 2015;Ganin & Atopkin 2018) have revealed differences between meadow-swampy D. sp.nov and forest D. ghilarovi for 15-17%.…”

In the Sikhote-Alin and Changbai Mountains of the Amur River region, earthworms of genus Drawida inhabit the northern boundary of their natural habitat. They are represented by the epigeic and anecic life-forms, three steady colour morphs and eight valid species, yet the genetic lineages of 11 have yet to be described. Based on mt-COI gene fragment sequence data, epigeic and anecic earthworms are shown to differ from one another at the interspecific level. Polymorphism and genetic intraspecific diversity are an obligatory sign for a species in the refuge even at the boundary of its distribution where this species occupies new ecological niches. The original habitats of the ancient Drawida black morph were within the Paleo-Amur River basin in the Late Neogene. Today, the meadow-swampy drawidas protrude far north along the Amur River floodplain up to the border of the last freezing in this region in comparison to the forest earthworms. However, at similar northern latitudes such as the Kuril Islands and the Sakhalin, Drawida are absent, because the soil on these islands during the last Ice Age was permafrost. The black epigeic drawidas only live in the floodplain meadows. The grey and brown morphs of the anecic species live in same forest biotopes, where they inhabit different soil horizons.

Key species of soil macrofauna -large soil saprophages, i.e. earthworms -have been studied in unique in terms of floristic and faunal diversity, as well as the most preserved forests of the southern Russian Far East. The results of studying taxonomic and functional diversity of earthworms, their biomass and abundance and patterns of temporal spatial distribution in summer seasons, are presented. The complete set of the main functional groups of earthworms (epigeic, epi-endogeic, endogeic and anecic) was found only in the best-preserved valley forests, with no traces of logging and fires over the last century. The earthworm community is not complete (one or two functional groups are missing) in one of valley forest that was partially cut down and affected by fires in recent decades and in hillside forests. Horizontal spatial distribution was analysed for the epi-endogeic and endogeic groups of earthworms, dominating in terms of biomass and occurrence. It was found that, in the summer season, the group of epi-endogeic species showed the "covering" type of distribution (regular distribution without aggregation), whereas the group of endogeic species showed the "spotty" type of distribution (aggregated distribution).

“…There are four earthworm families: Lumbricidae, Criodrilidae, Megascolecidae and Moniligastridae, while only one family, the Lumbricidae, is mainly represented throughout most of the territory of Russia. At the same time, Drawida ghilarovi Gates, 1969, a representative of the tropical family Moniligastridae, is endemic to the southern Far East and is typical for a number of forest, meadow and meadow-marsh communities (Ganin & Atopkin, 2018); however, the species is declining in number and is on the Red List of the Russian Federation (category II).…”

Impact of antibiotics as anthropogenic stressor for influencing bacterial evolutionary process – A review

A large number of human induced stressors are affecting natural evolutionary process through altering ecosystems and biodiversity. Antibiotics are one of the most commonly excreted pollutants released in environment since last eight decades. Antibiotics can alter genetic orientation of bacterial population and can exert selection pressure for emerging new taxon. In environments like soil and water, antibiotics directly or indirectly may affect many aspects of natural systems like biogeochemical cycles, nitrifications and decomposition process. All these may bring new selection pressure for bacteria not only in community or population level but also in species level.
