Haloxylon ammodendron (C. A. Mey.) Bunge is a host for the holoparasitic plant Cistanche deserticola Y. C. Ma, the original source of medicinal material known as Herba Cistanchis. The inter-simple sequence repeat marker was used to assess the genetic variations and relationships among six accessions of H. ammodendron with a total of 120 individuals collected from three localities in the Alxa Desert, Inner Mongolia, china. At each locality, individuals both parasitized (PP) by C. deserticola and non-parasitized (NP) were sampled. The results showed that Nei’s gene diversity and Shannon’s index of PP accessions were higher, but were not significantly different, from those of NP accessions. An unweighted pair-group method arithmetic average dendrogram showed two clusters, one that included all PP accessions, and the other the NP accessions. Genetic differentiation therefore existed between PP and NP accessions, which might be attributed to low gene flow between the NP and PP groups (Nm<1). However, the relationship between genetic distance and geographic distance within each group, although not statistically significant in this study, might be associated with high gene flow in both the NP and PP groups.

在锻炼心理学、社会学的相关研究基础上,从全民健身的视角对体育锻炼动机的分型与多元共存现象进行分析。将体育锻炼动机分为传统性动机(以"强身健体"为核心的锻炼动机)、现代性动机(以"身心发展"为核心的锻炼动机)、后现代性动机(以"休闲审美"为核心的锻炼动机)。指出体育锻炼动机存在多元共存现象,即多种类型的动机共存并且处于不断转化和发展之中,并借鉴中国社会的传统性、现代性、后现代性共存的"时空压缩"观点,对体育锻炼动机的多元共存现象进行了阐释。
