Abstract Farmland biodiversity is in alarming decline worldwide due to agriculture intensification. In this context, the umbrella species concept may help better targeting conservation efforts, focusing on whose requirements best cover those of other components biological communities. We test idea using little bustard ( Tetrax tetrax ), a strongly declining steppe bird depending extensive agric...

Abstract Grazing exclusion has been proved to be an effective approach for naturally restoring degraded rangelands. Still, the effect of this management practice on plant community composition and structure is ambiguous, especially under prolonged repeated drought events. Here, we investigated responses (i.e. incidence-based) abundance-based) short-term sheep grazing severe episode in arid step...

Introduction. An attempt to divide, according the territorial origin, a single data array made up of sizes skulls Iron Age series using multidimensional statistics has become goal this work. Materials and methods. Individual on male from territory South Caucasus (Armenia, Georgia, Azerbaijan) Steppe region Eastern Europe (Srubnaya culture Russian steppes, Moldavia Lower Don, Saka Turkmenistan) ...

For the first time, an assessment of phenotypic variability and genetic polymorphism was performed on endemic plants Scutellaria tuvensis Juz. growing in Tuva (five populations; Russia). Based morphological traits individuals, principal component analysis clustered individuals into three groups depending characteristics their habitats: group 1 turned out to be sampled from beach gravel, 2 a det...

A severe dust storm blanketing Central Asia on 3–4 November 2021 was investigated employing satellite remote-sensing, synoptic meteorological observations, reanalysis and HYSPLIT back-trajectories. The prevailing conditions showed an intensification of air subsidence over eastern Kazakhstan, featured in a typical omega-blocking system the region two troughs to its west east axis, one day before...

ABSTRACT In this paper we discuss recent developments in documenting the spread of millet across Eurasian steppes. We emphasize that, despite a proposal that consumption southern Siberia can be attributed to Early Bronze Age (i.e., late third early second millennium BC), at present there are no direct data for indicating prior Late Age, from 14th century BC. also full combined stable isotope an...

The article presents the study results of annual variability thunderstorm activity at nine climatic stations in Western Siberia over a fifty-year period from 1971 to 2020. revealed complex quasi-periodic structure series with most pronounced amplitude 7–8-year cycles for forest-tundra and 2–4-year cycle taiga zone, as well forest-steppes. A synchronous course increase decrease periods frequency...
