Cardamine hupingshanensis (K. M. Liu, L. B. Chen, H. F. Bai and L. H. Liu) is a perennial herbal species endemic to China with narrow distribution. It is known as an important plant for investigating the metabolism of selenium in plants because of its ability to accumulate selenium. However, the phylogenetic position of this particular species in Cardamine remains unclear. In this study, we reported the chloroplast genome (cp genome) for the species C. hupingshanensis and analyzed its position within Cardamine. The cp genome of C. hupingshanensis is 155,226 bp in length and exhibits a typical quadripartite structure: one large single copy region (LSC, 84,287 bp), one small single copy region (17,943 bp) and a pair of inverted repeat regions (IRs, 26,498 bp). Guanine-Cytosine (GC) content makes up 36.3% of the total content. The cp genome contains 111 unique genes, including 78 protein-coding genes, 29 tRNA genes and 4 rRNA genes. A total of 115 simple sequences repeats (SSRs) and 49 long repeats were identified in the genome. Comparative analyses among 17 Cardamine species identified the five most variable regions (trnH-GUG-psbA, ndhK-ndhC, trnW-CCA-trnP-UGG, rps11-rpl36 and rpl32-trnL-UAG), which could be used as molecular markers for the classification and phylogenetic analyses of various Cardamine species. Phylogenetic analyses based on 79 protein coding genes revealed that the species C. hupingshanensis is more closely related to the species C. circaeoides. This relationship is supported by their shared morphological characteristics.

2020年8月7日,在湖南壶瓶山国家级自然保护区进行兰科植物调查时发现5株野生兰花,经仔细观察和形态比较,鉴定为天府虾脊兰,隶属于兰科虾脊兰属,为湖南省新记录种.

From August 2012 to August 2015,20 infrared camera-traps were installed in a monitoring grid to investigate terrestrial fauna and avifauna population in the Hupingshan National Nature Reserve of Hunan Province,China.Based on 19 592 camera-days in the field,we identified 21 mammal species belonging to 4 orders and 11 families and 33 bird species belonging to 4 orders and 8 families.Among these,forest musk deer (Moschus berezovskii) was listed as Category Ⅰ state key protected wild animals and eight species as Category Ⅱ.Red-hipped squirrel (Dremomys pyrrhomerus) was recorded for the first time in the reserve.Carnivora had the highest species richness among mammals (9 species),followed by Artiodactyla (6 species) and Rodentia (5 species).Tufted deer (Elaphodus cephalophus),wild boar (Sus scrofa),redhipped squirrel,Reeve's muntjac (Muntiacus reevesi) and Hog badger (Arctonyx collaris) ranked as the five most abundant mammal species according to a relative abundance index.Passeriformes had the highest species richness in bird (25 species),followed by Galliformes (5 species) and Piciformes (2 species).Golden pheasant (Chrysolophus pictus),Temminck's tragopan (Tragopan temminckii) and spotted laughingthrush (Garrulax ocellatus) rank as the three most abundant bird species.In addition,we also analyzed daily and annual activity patterns of the six common species such as golden pheasant,Temminck's tragopan,red-hipped squirrel,tufted deer,wild boar and Reeve's muntjac.Our results provide basic information for long-term monitoring of the diversity and density of terrestrial fauna and avifauna inhabiting the Hupingshan region.
