“…The majority of Orthoptera in the boreal and temperate forest zones of the Palaearctic are associated with open habitats (Sergeev, 1992(Sergeev, , 1997. These grassland habitats often are created and maintained by disturbance (Theuerkauf & Rouys, 2006), which is especially important at the microhabitat scale.…”

“…We therefore investigated orthopteran communities in the natural landscape of the Russian Far East and compared the results with observations from the human and agriculturally dominated landscape of central Europe, because many taxa occur throughout the Palaearctic (Sergeev, 1992(Sergeev, , 1997. Hence, orthopteran assemblages in the Lazovsky State Nature Reserve (Primorsky region, Russian Far East) were studied to (i) determine their species composition and abundance in different natural and seminatural habitats, (ii) analyse orthopteran habitat require-ments in relation to habitat structure and microclimate and (iii) compare orthopteran habitat preferences there and in Europe where the same or closely related species occur.…”

Abstract. We investigate orthopteran communities in the natural landscape of the Russian Far East and compare the habitat requirements of the species with those of the same or closely related species found in the largely agricultural landscape of central Europe. The study area is the 1,200 km 2 Lazovsky State Nature Reserve (Primorsky region, southern Russian Far East) 200 km east of Vladivostok in the southern spurs of the Sikhote-Alin Mountains (134°E/43°N). The abundance of Orthoptera was recorded in August and September 2001 based on the number present in 20 randomly placed 1 m² quadrates per site. For each plot (i) the number of species of Orthoptera, (ii) absolute species abundance and (iii) fifteen environmental parameters characterising habitat structure and microclimate were recorded. Canonical correspondence analysis (CCA) was used first to determine whether the Orthoptera occur in ecologically coherent groups, and second, to assess their association with habitat characteristics. In addition, the number of species and individuals in natural and semi-natural habitats were compared using a t test. A total of 899 individuals of 31 different species were captured, with numbers ranging between 2 and 13 species per plot. Species diversity was higher in semi-natural habitats than natural habitats. There was a similar but non-significant pattern in species density. Ordination analysis indicated four orthopteran communities, which were clearly separable along a moisture and vegetation density gradient. The natural sites in the woodland area of the Lazovsky Zapovednik are characterized by species-poor and low-density orthopteran assemblages compared to the semi-natural sites. But, the natural sites have a higher diversity of habitat specialists. Our findings corroborate the hypothesis that intermediate habitat disturbance levels support particularly species-rich animal communities at high densities. Under such regimes, orthopterans presumably mostly profit from the high diversity in plant species, which generates great structural and microclimatic heterogeneity.

The geographic range analysis of 59 species of the family Vespidae (Hymenoptera) of northern Mongolia was performed using published sources and our own data. The longitude-latitudinal approach is supported for the chorological division. Chorological component of vespid fauna of northern Mongolia is mainly composed of Palaearctic polyzonal and sub-boreal species associated especially with sub-boreal semi-humid and sub-boreal semi-arid landscapes. Northern Mongolia together with Trans-Baikal region act as barrier to the latitudinal and longitudinal distribution of vespid wasps, and it can be called, as the BaikalMongolian faunal barrier. Four sub-endemic vespid species, Onychopterocheilus turovi (Kostylev, 1937), O. kiritshenkoi (Kostylev, 1940), Ancistrocerus rufopictus (Kostylev, 1940), Eumenes transbaicalicus Kurzenko, 1984 were defi ned to Mongolia.

Analysis of geographic centrality and genetic diversity in the declining grasshopper species Bryodemella tuberculata (Orthoptera: Oedipodinae)

Human-induced ecological and climatic changes have led to the decline and even local extinction of many formerly widely distributed temperate and cold-adapted species. Determining the exact causes of this decline remains difficult. Bryodemella tuberculata was a widely distributed orthopteran species before the mid-19th century. Since then, many European populations have suffered drastic declines and are now considered extinct or critically endangered. We used ecological niche modelling based on a large dataset of extant and extinct occurrence data to investigate whether poor climatic suitability in the periphery of its global range was a possible cause of the local extinction of the European populations of B. tuberculata. We also used population genetics based on the COI marker to estimate and compare the genetic diversity of extant populations. We found that Europe still provides highly suitable habitats close to the climatic optimum, contradicting the assumption of climate change as major driver of this decline. Instead, changes in land-cover and other anthropogenic modifications of the habitats at the local scale seem to be the major reasons for local extinctions. Genetic analysis suggests Central Asia as center of diversity with a stable population size, whereas the effective sizes of the remaining European populations are decreasing. We found European genetic lineages nested within Central Asian lineages, suggesting a Central Asian source distribution area. Our results suggest that the declining European populations represent relics of a formerly wider distribution, which was fragmented by changes in land-use. These relics are now threatened by limited connectivity and small effective population sizes. Specific conservation actions, such as the restoration of former or potential new habitats, and translocation of individuals from extant populations to these restored sites may help slow, stall, or even revert the extinction process.
