title: MODIS MOD09Q1 derived lake water surface dataset of the Qinghai-Tibet Plateau (2000 – 2012)
title: 基于MODIS MOD09Q1的青海、西藏湖泊水面数据集（2000~2012）

description: Tibetan Plateau has the largest number and size of inland lakes that located in the highest elevation on earth. Under the background of global warming, the spatio-temporal change process of these huge numbers and size of lakes are hot issues for researches of climate and environment changes in the plateau. However, impacted by the lack of spatio-temporal continuous lake dynamic dataset, the past researches did not clearly characterize the inter-annual and annual lakes’ variation rules. This paper introduced and released the lake water surface data set (8-day with 250 m spatial resolution) of Tibetan Plateau (Qinghai province and Tibet autonomous region) during the period of 2000 – 2012, which derived from the MODIS MOD09Q1 products by using the multistage segmentation and lake by lake automatic threshold determining extraction method. The total accuracy of the data set is 93.98%. The accuracy of cross comparison with other similar products and research results is higher than 86%. The data set accurately reflects the inter-annual and annual variation characteristics of lake water surface in the plateau during the past 10 years. The data set can be directly used to study the dynamic changes of the lake water in the plateau, but also can be used as input to the land surface process model or the regional climate model to study the role of lake water dynamic change in the regional hydrological and climate system.

title: Alpine grassland map (2010)
title: 2010年高原草地覆盖种类图

description: The Tibetan Plateau is primarily composed of alpine grasslands. Spatial distributions of alpine grasses, however, are not well documented in this remote, highly uninhabited region. Taking advantage of the frequently observed moderate resolution imaging spectroradiometer (MODIS) images (500-m, 8-day) in 2010, this study extracted the phenological metrics of alpine grasses from the normalized difference vegetation index time series. With the Support Vector Machine, a multistep classification approach was developed to delineate alpine meadows, steppes, and desert grasses. The lakes, permanent snow, and barren/desert lands were also classified with a MODIS scene acquired in the peak growing season. With ground data collected in the field and aerial experiments in 2011, the overall accuracy reached 93% when alpine desert grasses and barren lands were not examined. In comparison with the recently published national vegetation map, the alpine grassland map in this study revealed smoother transition between alpine meadows and steppes, less alpine meadows in the southwest, and more barren/deserts in the high-cold Kunlun Mountain in the northeast. These variations better reflected climate control (e.g. precipitation) of different climatic divisions on alpine grasslands. The improved alpine grassland map could provide important base information about this cold region under the pressure of rapidly changing climate.

title: CT dataset of three-dimensional morphology of the Jurassic Liaodactylus primus (Reptilia: Pterosauria)
title: 侏罗纪原始辽翼龙（爬行纲：翼龙目）头骨三维形态CT数据集

description: Liaodactylus primus is the earliest filter-feeding pterosaur, discovered from the Late Jurassic Tiaojishan Formation in Jianchang County, Liaoning Province of China, dated to about 160 Million years ago (161.8±0.4 – 159.5±0.6 Ma). The discovery of Liaodactylus primus documents a specialized feeding strategy among pterosaurs in the Mesozoic Yanliao Biota in Northern China, which contributes to understanding ecological diversity in reptiles of the biota. Here we provide a dataset of the holotype of Liaodactylus primus (PMOL-AP00031) from X-ray Computed Tomography (X-ray CT), including original CT slice images, reconstructed three-dimensional CT models of the mandibles, animated videos, and morphological character matrix for phylogenetic analysis. Data from CT scanning the skull of Liaodactylus primus will contribute to further studies of pterosaurs regarding their morphology, ecology, and phylogeny. Three-dimensional virtual models of the mandible of Liaodactylus primus can be 3D printed, with broad applications in research, teaching, and public outreach.

title: Fuel source shift or cut down cost: context-dependent adaptation strategies in closely related Neodon fuscus and Lasiopodomys brandtii against hypoxia
title: 供能来源转换或降低能量消耗：青海田鼠与布氏田鼠低氧下的适应策略比较研究

description: Oxygen is essential for most life forms. An insufficient oxygen supply can disrupt homeostasis and compromise the survival of organisms, and hypoxia-induced cardiovascular failure is fatal in many animals, including humans. Some species have adapted to hypoxic environments and evolved to endure such conditions, making them good models for studying the regulatory mechanisms involved in the cardiovascular system in response to hypoxia. To explore the coping mechanisms of cardiovascular system in hypoxic adaptation species with different life histories, we investigated the physiological and molecular responses of the cardiovascular systems of two closely related rodents, Qinghai vole (Neodon fuscus) and Brandt’s vole (Lasiopodomys brandtii), exposed to hypoxic (10% O2 for 48 h) and normoxic (20.9% O2 for 48 h) conditions. Kunming mouse (Mus musculus) was used as a comparison.
