Taxonomic inventory and distributions of Chenopodiaceae (Amaranthaceae s.l.) in Orenburg Region, Russia.

Background: Orenburg Region is located in the South Urals, mostly in the steppe zone and is characterised by various landscapes suitable for many Chenopodiaceae. The species of Chenopodiaceae are present in all major plant communities (saline vegetation, steppes, on limestone, chalk and sand, and as degraded or ruderal communities). In the steppe zone, many native subshrubby species (, , ) playing a crucial role in semi-deserts (known as southern steppes in the recent Russian literature) located southwards of Orenburg Region are locally found, and several annuals (, spp.

Metabolic rate, sleep duration, and body temperature in evolution of mammals and birds: the influence of geological time of principal groups divergence.

This study contains an analysis of basal metabolic rate (BMR) in 1817 endothermic species. The aim was to establish how metabolic scaling varies between the main groups of endotherms during evolution. The data for all the considered groups were combined and the common exponent in the allometric relationship between the BMR and body weight was established as = 0.

Two new species of (Copepoda, Harpacticoida, Canthocamptidae) from the Russian Arctic and comparison with (Claus, 1863).

Two new species of Chappuis, 1929 from the Russian Arctic from the species group are described: and A complete morphological comparison of the new species with the type species (Claus, 1863) was carried out. Significant interspecific differences were shown at the level of microcharacters, such as integumental sensillae and pores, ornamentation of segments of mouthparts and swimming legs, and pores on swimming legs. A significant correlation has also been shown in the shape of the caudal rami of the females and the antennules of the males, which is likely caused by an evolutionary sexual arms race.

Two new species of (Bacillariophyta) from Southeast Asia.

We present light and scanning electron microscopical observations on two new species of Bory sensu stricto from Southeast Asia. Chudaev, Glushchenko, Kulikovskiy & Kociolek, differs from taxa with similar outline and size by the combination of simple drop-like external raphe endings deflected to the primary valve side, presence of well-developed external longitudinal grooves and relatively low lineolae density. Chudaev, Glushchenko, Kulikovskiy & Kociolek, can be discriminated from the taxa of similar valve shape and size by consistently lower lineolae density, and from the majority of them also by the structure of external proximal raphe endings with small projections in proximal parts and larger triangular insertions in distal parts.

Leaf epidermal micromorphology in (Asparagaceae): diversity and taxonomic significance.

Micromorphological characters of leaf epidermis were investigated in 69 species of using scanning electron microscopy. Sculpture of epidermis varies from smooth to verrucose and rugose in the genus. The abaxial epidermis of some species bears papillae, whereas the adaxial surface uniformly lacks the papillae.

Fleroff goes digital: georeferenced records from "Flora des Gouvernements Wladimir" (Fleroff, 1902).

Background: Global Biodiversity Information Facility (GBIF) has uneven data coverage across taxonomic, spatial and temporal dimensions. Temporal imbalances in the data coverage are particularly dramatic. Thus, 188.

Contribution to the "Atlas of the Russian Flora": Twelve local floras of European Russia.

Background: The purpose of this dataset is to deliver to a wider audience in the form of GBIF-mediated data vast floristic materials collected by the author across various localities of European Russia from 2001-2019 (Arkhangelsk, Tver, Vladimir, Tula, Lipetsk, Voronezh Oblasts, Krasnodar Krai, City of Moscow and Komi Republic). Taxonomic data on vascular plants for ten locations were mobilised from the papers and technical reports published in Russian and standardised. Floristic treatments for two locations (Yasnaya Polyana and Tsaritsyno) have never been published before.

TUL Herbarium: collections of vascular plants of Tula Oblast, Russia.

Background: TUL Herbarium presents collections from Tula Oblast stored at the Tula State Lev Tolstoy Pedagogical University, Russia, which is an educational and scientific institution that supports various types of scientific activities, including research on biodiversity and nature conservation. The university is a holder of some biological collections, such as herbarium of vascular plants, mosses and fungi collected mainly throughout Tula Oblast and from adjacent regions.

New Information: The collections of vascular plants (9,000 specimens) were imaged in December 2019 and January 2020.

"Flora of Russia" on iNaturalist: a dataset.

Background: The "Flora of Russia" project on iNaturalist brought together professional scientists and amateur naturalists from all over the country. Over 10,000 people were involved in the data collection.

New Information: Within 20 months, the participants accumulated 750,143 photo observations of 6,857 species of the Russian flora.

MHA Herbarium: Eastern European collections of vascular plants.

Background: World herbaria with 387.5M specimens (Thiers 2019) are being rapidly digitised. At least 79.

Description of a new species of the genus Verhoeff, 1917 and redescription of Borutzky, 1957 from the southeast of European Russia (Isopoda, Oniscidea, Agnaridae).

A new species of woodlice, Gongalsky & Turbanov, is described from Kalmykia, NE Pre-Caspian region, Russia. Borutzky, 1957 from the same area is also redescribed. Diagnostic features of these species as well as affinities within the genus are provided and discussed.
