Dataset on the interview-based survey of Moscow bicycle infrastructure.

The data were collected using Computer Assisted Telephone Interview with a questionnaire set of closed-ended and open-ended questions. Respondents' phone numbers were randomly generated. The survey sample included 1000 adult citizens of Moscow - active and potential users of bicycles (in equal proportions) who take or can take regular rides to destinations up to 5 km away, as of August 2018.

Regional free cash flow dataset: An approach to regional performance evaluation.

This data article provides estimates on the Russian regions' aggregate free cash flow, which is not covered by national statistics of major countries. A proper microeconomic model was adapted to regional level data to derive a synthetic indicator of a regional economy's performance. The data contributes to the set of regional performance measures thus enabling a new look at studies of economic growth and development.

Ecological development and genetic diversity of Microcystis aeruginosa from artificial reservoir in Russia.

Microcystis aeruginosa is a well-known Cyanobacterium responsible for the formation of toxic water blooms around the world. Shallow, warm, and eutrophic reservoirs provide the most favourable conditions for M. aeruginosa development.

Efficiency of transfer of essential polyunsaturated fatty acids versus organic carbon from producers to consumers in a eutrophic reservoir.

One of the central paradigms of ecology is that only about 10% of organic carbon production of one trophic level is incorporated into new biomass of organisms of the next trophic level. Many of energy-yielding compounds of carbon are designated as 'essential', because they cannot be synthesized de novo by consumers and must be obtained with food, while they play important structural and regulatory functions. The question arises: are the essential compounds transferred through trophic chains with the same efficiency as bulk carbon? To answer this question, we measured gross primary production of phytoplankton and secondary production of zooplankton and content of organic carbon and essential polyunsaturated fatty acids of ω-3 family with 18-22 carbon atoms (PUFA) in the biomass of phytoplankton and zooplankton in a small eutrophic reservoir during two summers.
