Transboundary migration of Loxostege sticticalis (Lepidoptera: Crambidae) among China, Russia and Mongolia.

Background: The beet webworm, Loxostege sticticalis, a worldwide pest of many crops, performs a seasonal migration, causing periodic outbreaks in Asia, Europe and North America. Although long-distance migration is well documented in China, patterns of transboundary migration among China, Russia and Mongolia are largely unknown. We performed a phase analysis of L.

Sequencing, Analysis and Organization of the Complete Genome of a Novel Baculovirus Nucleopolyhedrovirus (CaabNPV).

, a virus family characterized by a single large double stranded DNA, encompasses the majority of viral bioinsecticides, representing a highly promising and environmentally friendly pesticide approach to insect control. This study focuses on the characterization of a baculovirus isolated from larvae of (Erebidae, Lymantriidae) collected in Mongolian pinaceae forests. This new isolate was called nucleopolyhedrovirus (CaabNPV).

Phylogeography and Ecological Niche Modeling of the Alashan Pit Viper (; Reptilia, Viperidae) in Northwest China and Adjacent Areas.

The joint impacts of historical geological events and Quaternary climatic oscillations in Northwest China on species evolution have been examined extensively in plant under a phylogeographic perspective. However, animal phylogeographic analyses in this region are still limited. The Alashan pit viper, , occurs primarily in arid Northwest China and adjacent areas.

Nitrogen isotope pattern in Mongolian larch stands at the southern Eurasian boreal forest boundary.

In the last decades a drastic increase in air temperature but a stable precipitation regime in Mongolia has led to gradual drying conditions. Thus, we evaluated the effect of spatial and climatic characteristics on the soil-plant nitrogen dynamics in three representative larch stands (Larix sibirica) with different geographical and climatic conditions using stable nitrogen isotopes. The results showed significant differences in the soil inorganic N content among sites and consequently a different isotopic composition in the plant-soil system.

Spatial variations in larch needle and soil δN at a forest-grassland boundary in northern Mongolia.

The spatial patterns of plant and soil δN and associated processes in the N cycle were investigated at a forest-grassland boundary in northern Mongolia. Needles of Larix sibirica Ledeb. and soils collected from two study areas were analysed to calculate the differences in δN between needle and soil (ΔδN).
