Sequences of 28S rDNA across Acari, though with variable region, were not randomly distributed, with the expansion segments being more variable than the core regions and with an increasing sequence divergence with taxonomic distances.

散布图显示，转换取代与颠换取代有类似的线性变化；支序分析及群聚分析的亲缘关系显示，同科及同属内的成员都群聚的很好，全爪蟎属与小爪蟎属的亲缘关系近，与叶蟎属较近的是岩蟎属。28S rDNA的序列特性显示，其核心序列适合分析较高阶的蟎蜱亲缘，而展延区则可应用於低阶的分析。

We choose the arid land of northwestern China as our study area because of its extensive area, specific geographical location, dry climate, varied topography, vulnerable ecosystems and long-term human disturbance, as well as the existence of current conflicts between economic development and environmental protection. Based on the literature, we choose ten desert species with clear and relatively accurate geographical distribution ranges to model their distributions:Anabasis brevifolia, Atraphaxis frutescens, Calligonum mon-golicum, Ephedra przewalskii, Gymnocarpos przewalskii, Haloxylon ammodendron, Haloxylon persicum, Ka-lidium cuspidatum, Salsola laricifolia, and Sympegma regelii.

：选择面积广阔、地理位置特殊、气候干旱、地形地貌多样、生态系统脆弱以及人类活动长期干扰，而且目前面临着西部大开发和环境保护双重矛盾的西北干旱区作为研究区域，通过收集西北干旱区多种优势种和常见种的地理分布资料，选取10种分布范围相对明确、资料相对齐备的荒漠植物种：短叶假木贼、木蓼(A- traphaxis frutescens)、沙拐枣、膜果麻黄、裸果木、梭梭柴、白梭梭、尖叶盐爪爪、松叶猪毛菜(Salsola lar- icifolia)和合头草，定量分析其地理分布与气候因子的关系，并据此估测其潜在中心分布区和潜在最大分布范围，与实际分布范围进行比较。

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法，对这三种模型的基本原理、模型的构建过程进行对比分析，在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量，并对三种方法的特点、预测的准确度和适用范围进行了比较分析，结果表明：(1)马尔可夫链预测模型属于中长期预测，预测的结果为区间预测，但对于害鼠种群数量的预测来说已经达到要求，通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测，预测的结果都比较准确，这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态，马尔可夫链模型是比较好的模型。

Based on the results, it has found that six distinct layers can be identified from lateral to medial in the olfactory bulbs, and the adults have more cells than the subadults. Ventricles of the adults take up larger vacuity, have richer choroids plexus, and primordial pallium and primordial hippocampus of them are more developed than the subadults, in which the primordial piriform is well-developed. Ventral to the primordial hippocampus, there is a septal area which can not be divided into medial and lateral parts in both adults and subadults, nor there is lateral limiting sulcus to separate the primordial piriform and the corpus striatum, but only in the subadults, a medial limiting sulcus can be clearly identified to separate the primordial hippocampus and the septal area. Besides, the corpus striatum of Onychodactylus fischeri is paleostriatum. The cell group that located at two sides of the third ventricle is amygdale, and shape and size of neurons within the telencephalon are poorly differentiation.

结果表明：爪鲵嗅球内细胞从外到内大致可分为6层结构，亚成体的细胞数量少于成体；成体爪鲵的侧脑室所占空间较大，脉络丛更为丰富，原始大脑皮层和原始海马都比亚成体发达，后者大脑内原始梨状区较为发达；隔区位于原始海马的下方，成体和亚成体都没有外侧隔核和内侧隔核之分，也没有外侧界沟作为原始梨状区和纹状体的分界，而在亚成体的侧脑室壁有内侧界沟区分原始海马和隔区，成体则没有；此外，爪鲵的纹状体属于古纹状体，杏仁核是位于第三脑室两侧的两个细胞团，端脑内细胞形态和大小分化较为单一。
