Characterization of the Complete Mitochondrial Genome of Przewalski's Gazelle Procapra przewalskii in Bovidae Family of Artiodactyla

The Przewalski's gazelle,Procapra przewalskii,is one of the most endangered species in China,and is now found only in a single small area around the Lake Qinghai.In this study,the complete mitochondrial genome of P.przewalskii was determined and annotated.The circular genome is 16 547-bp long,containing13 protein-coding genes,22 transfer RNA genes,2 ribosomal RNA genes,and a predicted control region.The overall base composition was 34.0% A,24.7% C,28.3% T,and 13.0% G,with a total A + T content of 62.3%.Phylogenetic analysis of all 19 Bovidae species indicated that P.przewalskii showed a close relationship to Procapra gutturosa.Our results provide a great deal of useful information on further studies for conservation biology of Przewalski's gazelle.

基于空间建模语言的普氏原羚生存能力模型的构建

为揭示青海湖地区普氏原羚的生存能力,建立普氏原羚生存能力空间模型,分为狼捕食模块、普氏原羚生存模块、人类活动及政策模块、食物丰富度模块和羊生长模块。普氏原羚生存能力模型基于空间建模语言实现,采用SME中的SML语言标准。利用空间建模语言直观反映模型的层级关系、模型与空间的关系、空间数据与时间数据的融合以及模型的可视化模拟和预测。
