Study On Physiological Ecology Of Muntiacus Crinifrons And Microhyla Beilunensis In Xianxialing Mountains,Suichang

Xianxialing mountains have high biodiversity,which is the key area of terrestrial biodiversity protection in China.Muntiacus crinifrons and Microhyla beilunensis from Niutoushan and Jiulong Mountain in Suichang Xianxialing mountains were selected to study their physiological ecology as the main research objects.The research contents are as follows:(1)the activity rhythm of M.crinifrons in Niutou mountain was studied based on infrared camera technology,and the potential suitable area of black muntjac was predicted by MaxEnt model;(2)based on the infrared camera technology,the niche differentiation strategy of two Muntiacus species in Niutou mountain was studied;(3)by morphological comparison,16S r RNA sequence alignment and phylogenetic analysis,the newly distributed amphibian in Suichang Xianxialing mountains was identified,and the sexual dimorphism of the species was studied;(4)to study the effects of niche differentiation strategy and phylogenetic relationship on the calls of three Microhyla species of in Suichang by quantitative analysis of their advertising call parameters and other reported data.The main research results are as follows:1.Analyses of activity rhythm and prediction of potential suitable distribution in M.crinifronsIn this work,we based on infrared camera technology,the activity rhythm of black muntjac was studied,and the potential suitable areas of M.crinifrons in Zhejiang,Fujian,Anhui and Jiangxi provinces were predicted by MaxEnt model.The results as showed as follows:(1)the annual activity peak season of M.crinifrons is summer,and the daily activity peak is 0700-0900 h and 1600-1800 h;(2)temperature is an important factor affecting the activity of M.crinifrons,and the optimum temperature range is 18-28?;(3)the area of suitable habitat was around 25980.62km~2,which only accounted for 4.87%of the total area;(4)the potential suitable distribution area of black muntjac can be divided into four areas2.Niche Differentiation of M.crinifrons and M.reevesIn this work,we study on niche differentiation strategy of two species of muntjac by infrared camera.The results as showed as follows:(1)the daily peak activity of M.reeves is 0600-0800 h and 1800-2000 h,and M.crinifrons is 0800-1000 h and 1600-1800 h;(2)M.reeves prefers to inhabit in laurilignosa,and M.crinifrons prefers to inhabit in aciculiailvae;(3)the activity frequency of M.crinifrons was higher in the altitude range of 800 m-1000 m than that of M.reeves,and lower in the altitude range of 1000-1400 m than that of M.reevesi;(4)the niche differentiation strategies of M.crinifrons and M.reeves in Niutoushan mountains of Suichang are mainly habitat selection,feeding sites and diurnal activity rhythm.3.Sexual Dimorphism of M.beilunensis from Jiulongshan Mountain,ZhejiangIn this work,we identified a new species of Microhyla beilunensis in Suichang,and studied its sexual dimorphism through morphological comparison,16S r RNA sequence alignment and phylogenetic analysis.The results as showed as follows:(1)the species of the female frog in Jiulongshan population was identified as M.beilunensis,and its geographical distribution was widened;(2)M.beilunensis displays female-biased sexual size dimorphism;(3)the mean value of LLAH in males was larger than female after removing the effect of SVL.4.Acoustic divergence in advertisement calls among three sympatric Microhyla speciesIn this work,we quantied analysis of their advertising call parameters and other reported data to study the effects of niche differentiation strategy and phylogenetic relationship on the calls of sympatric Microhyla species.The results as showed as follows:(1)CVs of all spectral parameters were smaller than 5%,whereas the CV of CI was larger than 10%within individual of the three sympatric Microhyla species;(2)body size was a key factor that leads to among-individual variation in advertisement calls of Microhyla species;(3)acoustic divergence in call structure existed in the three sympatric Microhyla species;(4)the PGLS analysis showed that phylogeny affected the NP,DF and SVL vs.CD and SVL and DF vs.NP,but not DF vs.SVL.
