This study presents the modern glacier dynamics in Mt. Tsambagarav in the Mongolian Altai Mountain Range over the last four decades. This is the first review of this type of glacier dynamics for this massif. Changes in glacier area in Mt. Tsambagarav are estimated using normalized indexes (Normalized Difference Snow Index and Normalized Difference Principal Component Snow Index). Spatial distribution of the modern glaciers delineated with Landsat Multispectral Scanner (MSS: resolution of 80 m), Landsat Thematic Mapper (TM: resolution of 30 m) and Landsat Operational Land Imager (OLI: resolution of 30 m) imageries. Result shows that Mt. Tsambagarav has lost 51.7% of the glacier area from 132.24 km2 in 1977 to 63.92 km2 in 2017. The loss in glacier area for Mt. Tsambagarav during the last 40 years reflect the rapid response of the modern glacier to climate change, i.e., it is highly sensitive to solar insolation and/or rapidly rising local and regional mean annual temperatures. The remote sensing data and field survey suggest that the modern glaciers would be disappeared on a scale of decades. Rapid melting of the glacier in this massif contributes to surface water resources in western Mongolia. This study demonstrates the importance of spatial analysis in the remote area for understanding the context of changes in the modern glaciers.

Nebria (Pseudonebriola) tsambagaravsp. nov. is described from an alpine altitude in the Mongolian Altai. The new species is separated from other two Pseudonebriola species from the Mongolian Altai Mountain range, N. kerzhneri and N. medvedevi, by morphometric and morphological analyses. The new species and its habitat are illustrated, the subgeneric key is amended, and a distribution map is given.

Mountain Aj Bogd is one of branch mountains the mount systems Mongol Altai, which is located at the middle part of Mongol Altai mountain. Mountain Aj Bogd is similar with surface typology, deposits, form relief, erosion and accumulation process, mountain side, dissection, age and land­scape of main mountains of Mongol Altai. Aj Bogd Mountain is a mounting system had existed which surrounding by valleys and depressions and related by kotal and pass from the main ridge of the Mongolian Altai mountains. The Aj Bogd Mountain segregated to the east by Gobi Khonin Us, to the north from the mountain Khubch by pass Zoolin Bogd and the Mongol Altai mountain by depressions of Alag lake, to the west from mountains Ikh Tayan by dale of the Tuhum,Tooroi, to the south by Nomingiin gobi. The highest peak of this mountain Aj Bogd is 3093.3 m high above the sea level. The relief and peak of a mountain is mostly cupola or plane shaped because of in longest time weathered by wind and water.

The Mongolian Altai mountain range stretches from east to west for more than 800 kilometers, and its forest cover is considered the southwestern boundary of the distribution of Mongolian forests and is characterized by a unique combination of high-mountain and desert ecosystems. Siberian larch (Larix sibirica Ledeb.) is one of the main forest-forming tree species in the Mongolian Altai and covers 112.0 thousand ha of area and is distributed at an altitude of 2300 to 2700 m a.s.l. In this study, we attempted a comparative study of tree growth rates in larch forests, which are associated with four different altitudinal zones in the Mongolian Altai, aimed at determinining the lower and upper limits of forest distribution in this region. We used the natural quantitative indicators in this study. We carried out the diameter growth rate analyses on 15 model tree samples taken from the Mongolian Altai and 4 samples from Central Khangai regions. All the trees were divided into fast-growing and slow-growing. The results of the assessments showed that 60 percent of the studied forests belonged to slow-growing forests. Slowest growth rate was observed in the forests of Khan Taishir and Khar Azarga mountains, which are the southernmost tip of conifer forest distribution in Mongolia. For the first time in Mongolia we observed that the upper limit of larch forests reached up to 2700 m a.s.l. Such slow rate of tree growth in larch forests is the result of the existing harsh continental climate, aridity, and high altitudinal distribution in the Mongolian Altai. Our findings can become the scientific basis for the development of a sustainable forest management plan in the forests of the Mongol Altai, taking into account the different growth rate between stands.

Neural Adaptations

Abstract. Playing a musical instrument professionally has been shown to lead to structural and functional neural adaptations, making musicians valuable subjects for neuroplasticity research. Here, we follow the hypothesis that specific musical demands further shape neural processing. To test this assumption, we subjected groups of professional drummers, professional woodwind players, and nonmusicians to pure tone sequences and drum sequences in which infrequent anticipations of tones or drum beats had been inserted. Passively listening to these sequences elicited a mismatch negativity to the temporally deviant stimuli which was greater in the musicians for tone series and particularly large for drummers for drum sequences. In active listening conditions drummers more accurately and more quickly detected temporally deviant stimuli.
