In this paper, we show the existence and uniqueness of solutions to a large class of SFDEs with the generalized local Lipschitzian coefficients. Some moment estima- tes of the solutions are given by establishing new Ito operator inequalities based on the Razumikhin technique. These estimates improve, extend and unify some related results including exponential stability of Mao （1997） [20], decay stability of Wu et al. （2010,2011） [32,33], Pavlovic et al. （2012） [24], asymptotic behavior of Luo et al. （2011） [18] and Song et al. （2013） [26]. Moreover, stochastic version of Wintner theorem in continuous space is established by the comparison principle, which improve and extend the main results of Xu et al. （2008 [39], 2013 [36]）. When the methods presented are applied to the SFDEs with impulses and SFDEs in Hilbert spaces, we extend the related results of Govindana et al. （2013） [7], Liu et al. （2007） [15], Vinod- kumar （2010） [29] and Xu et al. （2012） [35]. Two examples are provided to illustrate the effectiveness of our results.

栖息地荒漠化对蜥蜴群落组成的影响

栖息地改变往往对动物群落及其物种多样性有重要影响,但是目前关于栖息地荒漠化如何影响蜥蜴的群落组成鲜有研究。在内蒙古自治区鄂尔多斯市准格尔旗和达拉特旗地区通过样线法调查了三类不同荒漠化程度样地上的蜥蜴群落组成差异,用典范对应分析探究了关键的影响因素。结果表明,栖息地荒漠化使蜥蜴的群落组成发生显著变化,从固定沙丘、半固定沙丘到流动沙丘,草原沙蜥均是蜥蜴群落的优势物种,密点麻蜥逐渐减少,丽斑麻蜥则消失于荒漠化严重的半固定沙丘和流动沙丘中。随栖息地荒漠化程度的增加,蜥蜴的数量显著减少,密度显著降低,蜥蜴物种的丰富度、香农-威纳(Shannon-Weaver)多样性指数和皮洛(Pielou)均匀性指数均逐次显著下降,而辛普森(Simpson)优势度指数则逐次显著升高。这说明荒漠化不仅使蜥蜴群落组成变得简单,同时造成了蜥蜴物种多样性的下降甚至丧失。荒漠化也使蜥蜴的栖息条件发生显著变化。植被高度、油蒿比例、裸地比例、隐蔽度、表层土壤含水量和表层土壤孔隙度在三类栖息样地之间均存在极显著差异。典范对应分析结果表明,这些环境因子与蜥蜴群落组成的变化密切相关。总体而言,草原沙蜥偏好裸地,密点麻蜥偏好隐蔽性好且土壤湿润又疏松的区域,而丽斑麻蜥则偏好植被高的区域。
