| 1 | Spatial and temporal variability in vegetation cover of Mongolia and its implications显示文摘In this paper, we attempted to determine the most stable or unstable regions of vegetation cover in Mongolia and their spatio-temporal dynamics using Terra/MODIS Normalized Difference Vegetation Index(NDVI) dataset, which had a 250-m spatial resolution and comprised 6 periods of 16-day composited temporal resolution data(from 10 June to 13 September) for summer seasons from 2000 to 2012. We also used precipitation data as well as biomass data from 12 meteorological stations located in 4 largest natural zones of Mongolia. Our study showed that taiga and forest steppe zones had relatively stable vegetation cover because of forest characteristics and relatively high precipitation. The highest coefficient of variation(CV) of vegetation cover occurred frequently in the steppe and desert steppe zones, mainly depending on variation of precipitation. Our results showed that spatial and temporal variability in vegetation cover(NDVI or plant biomass) of Mongolia was highly dependent on the amount, distribution and CV of precipitation. This suggests that the lowest inter-annual CV of NDVI can occur during wet periods of growing season or in high precipitation regions, while the highest inter-annual CV of NDVI can occur during dry periods and in low precipitation regions. Although the desert zone received less precipitation than other natural zones of the country, it had relatively low variation compared to the steppe and desert steppe, which could be attributed to the very sparse vegetation in the desert. | Sumiya VANDANDORJ Batdelger GANTSETSEG Bazartseren BOLDGIV | 2015 | Journal of Arid Land2015，7，4： | 4 |

| 7 | Metagenetics of fairy rings reveals complex and variable soil fungal communities显示文摘Although fairy rings are widely observed,little is known about the community processes associated with them.Here,we studied fairy rings in a natural grassland in northern Mongolia by sampling soils outside(future stage),directly under(present stage),and within(past stage)the rings,to represent different time stages during the expansion of fairy rings.Soil DNA was extracted for amplicon sequencing of the fungal ITS1 region.The present stage had reduced fungal diversity and different fungal communities toward the other stages.Most strikingly,there was an increase in the pathogenic fungus Gibberella baccata in the present stage of most rings and the saprotrophic fairy ring fungus Lepista luscina in several.However,no mushrooms of Lepista had been recorded from any of these rings during several years of observation.Known fairy ring fungi were not found in the present stage of every ring,even in some known rings to have previously displayed mushrooms of such species.It is possible that these fungi occurred or were more abundant at the unsampled leading edge of the ring.The increase in G.baccata is intriguing,but its importance,if any,is unclear.It is also unclear whether consortia of fungi or other microbes might be present in these rings.The absence or low abundance of the previously reported fairy ring fungal species suggests that their presence is transient,with rapid replacement by other fungi.No differences in soil parameters were found between the fairy ring stages,except for aluminum.There is a need for broader sampling,including analysis of non-fungal biota,to understand the functional diversity of fairy ring fungi and the consequences for plant communities. | Siyu XU Ke DONG Sangseob LEE Matthew Chidozie OGWU Sainbileg UNDRAKHBOLD Dharmesh SINGH Dagvatseren ARIUNZAYA Orsoo ENKHMANDAL Laura A.SPENCE Anarmaa SHARKHUU Brenda B.CASPER Jonathan M.ADAMS Bazartseren BOLDGIV | 2023 | Pedosphere2023，33，4： | 0 |
