Species abundance distributions (SADs) are increasingly used to investigate how species community structure changes in response environmental variations. SAD models depict the relative of recorded a and express fundamental aspects structure, namely patterns commonness rarity. However, influence differences conditions on characteristics is still poorly understood. In this study we carabid beetle...

Rodents are a major constraint to forage production for livestock in Mongolia. A technical program to identify the magnitude of the problem and strengthen the research capabilities of Mongolian rodent specialists was initiated in 1994. The Brandt's vole is the most widespread and the most detrimental rodent to the steppes of Mongolia. Limited resources inhibit activities by the Mongolian Plant ...

Soil nematodes are important contributors to soil biodiversity. Nonetheless, the distribution patterns and environmental drivers of nematode communities poorly understood, especially at large scale, where multiple variables covary. We collected 520 samples from 104 sites representing alpine meadow steppe ecosystems. First, we explored community characteristics compared between Then, examined co...

Different species of gazelles are among the most endangered mammals on the Asian steppes and occur in the central, southern and northwestern regions of Iran. The previous conservation efforts in this region have been incomplete due to confusion about the phylogenetic relationship among various populations. So that, different conservation programs such as ex-situ breeding and transfer of captive...

Relationships between steppe vegetation, human practices and climate changes in the past are crucial to disentangle development Eurasia. In this frame, our study investigates (1) modern pollen-vegetation relationships (2) activity Holocene record of Vanevan peat (south-eastern shore Lake Sevan, Armenia), using a multiproxy approach including sediment geochemistry (XRF), pollen, Non-Pollen Palyn...

Improvement of dendrochronological crops yield reconstruction by separate application earlywood and latewood width chronologies succeeded in rain-fed semiarid region. (1) Background: Tree-ring have been successfully applied for models. We propose separated as possible predictors improving the fitness (2) Methods: The generalized series main (spring wheat, spring barley, oats) were investigated ...

Over the period 2007–2019, author’s censuses of steppe birds in Azov-Black Sea dry-steppe enclave determined five species as dominants and co-dominants by their abundance. Thus, Melanocorypha calandra dominates throughout whole area, Emberiza 4 subregions co-dominates 5 subregions, Motacilla feldegg, hortulana, Anthus campestris, Alauda arvensis dominate 1 subregion do not or co-dominate 1–4 su...
