A study was conducted on the identifications of the degraded samples of sika deer (Cervus nippon) and red deer (Cervus elaphus) by phylogenetic and nucleotide distance analysis of partial Cytb and 12s rRNA genes sequences. 402 bp Cytb genes were achieved by PCR-sequencing using DNA extracted from 8 case samples, and contrasted with 27 sequences of Cytb gene downloaded from GenBank database. The values of three nucleotide distance between three suspected samples and sika deer were identical (0.026±0.006), which was smaller than the smallest nucleotide distance between eastern red deer and sika deer (0.036). Furthermore, phylogenetic analysis of sika deer and red deer indicated that the evidences located within the same cluster as sika deer. The evidences were sika deer materials. As the same way, other three suspected samples were derived from red deer. The results were further confirmed by phylogenetic and nucleotide distance analysis of 387 bp 12s rRNA gene. The method was powerful and less time-consuming and helpful to reduce the related cases with wildlife. 展开更多

[Objective] To introduce an improved method for DNA extraction from the faeces of red deer. [Method] Based on the traditional method of CTAB lysis, we proposed an improved DNA extraction method according to the characteristics of red deer faeces. [Result] This improved method extracted high-quality fecal DNA from Tianshan red deer and amplified the mitochondrial cytochrome b gene. With the muscle and fur DNA of red deer as the control, the sequencing results further con- firmed the reliability of the method. [Conclusion] The method requires no proteinase K in the process of extraction, and the extracted DNA can be used for PCR ampli- fication directly without the purification of DNA purification kit, thus, it is cost-saving. 展开更多

The Tibet Shannan Red Deer Nature Reserve is the center of the geographic distribution of Tibetan red deer. This paper presents the results of DNA analysis of 199 red deer fecal pellet groups collected during 2013 and 2014 during the green-plant period. We successfully extracted DNA from 87 DNA pellet groups and determined individual identification with 12 microsatellite loci. We evaluated the genetic diversity of the population and various population estimates with Capwire in R software. The87 successfully extracted pellet groups were from 50 individuals. In the population, the average number of alleles was 7.58 ± 0.18, the average effective number of alleles was 4.58 ± 0.15, and average polymorphism information content was 0.67 ± 0.01. Among the 12 loci,only T123 was moderately polymorphic; the other 11 loci were highly polymorphic. Expected heterozygosity ranged from 0.45 to 0.91, with an average of 0.72 ± 0.01, and average observed heterozygosity was 0.52 ± 0.11.Although Tibetan red deer remains endangered, the high genetic diversity indicates that this population has a good chance of recovery. This study provided insight that could be used by the local forestry department to develop programs to protect Tibetan red deer. 展开更多

We studied species of plants foraged by red deer in the Muling forest region of northeastern China during January 2014 and 2015. We focused on nutritional composition, energy content, and the digestibility of these plants. Crude protein content varied by plant species.Average crude protein content was 7.5 ± 1.7% of dry matter, ranging from 4.5 to 10.3%. Crude lipid content did not vary by species and averaged 7 ± 1.5%(range5.4–9.8%). Non-fiber carbohydrate(NFC) and neutral detergent fiber(NDF) content varied broadly with average values being 20.1 ± 4.8%(range 13.5–28.8%) and64.7 ± 5.9%(range 53.5–71.8%), respectively. Energy content ranged from 16.7 to 19.7 k J/g. Average dry matter digestibility(DMD) was 46.1 ± 4.8%, with a range from38.7 to 54.6%. Only three plants, Saussurea manshurica,Aralia elata and Equisetum hyemale exhibited DMD [ 50%. NFC content explained most of the variation in energy content(r = 0.451). In contrast, energy content was inversely related to NDF(r =-0.443). There was no correlation between crude protein, crude lipid, and energy content(r= 0.004, r=-0.190). S. manshurica,A. elata and E. hyemale had higher NFC and lower NDF content. Thus, these species offered the greatest nutritional value for wintering red deer in the study area. Along with high CP and NFC content, Taxus cuspidate also had high lignin content, and was thus, considered a good forage species for red deer. 展开更多

Red deer can adjust to seasonal change of forage quality to maintain a relatively constant crude protein level (21. 1±4.0, 14.7± 1 .0, 11. 1± 1. 1 and 6.5 ±0.8 in spring. summer. fall and winter. respectively). Apparent protein digestibility is variable from -99.9% to 97.5%, depending upon season and forage type. True protein digestibility is 99%. Digestion of protein is significantly influenced by phenolics in diets.Minimumm digestible energy intase of 153.5kcal/kg0.75/day is necessary to maintain a positive nitrogen balance. Red deer recycles 18-85% of the urea produced and urea kinetic parameters (urea pool size, urea entry rate and urea excretion rate) are correlated to plasma urea conccntration. Rumen NH3-N production changes with season, but seasonal changcs in other NH3-N kinetic parameters (NH3-N concentration, NH3-N pool size and NH3-N outflow rate) are in dispute. Protein metabolism may be promoted in response to cold strcss. Endogenous urinary nitrogen is 0.09 (red deer) and 0. 16 g N/kg0.75day (elk), and metabolic frcal nitrogen is 5.58 g N/kg dry-matter intake. Protein requirements ranges from 100 g/kg DM to 170 g/kg DM for red deer of various ages and physiological stages. In conclusion.the knowledge of protein nutrition of red deer is limite.Much work is urgently needed in metabolism and requirements of protein before the appropriate feeding standard of red deer is coming. 展开更多

Hyperspectral(HS)image classification is a hot research area due to challenging issues such as existence of high dimensionality,restricted training data,etc.Precise recognition of features from the HS images is important for effective classification outcomes.Additionally,the recent advancements of deep learning(DL)models make it possible in several application areas.In addition,the performance of the DL models is mainly based on the hyperparameter setting which can be resolved by the design of metaheuristics.In this view,this article develops an automated red deer algorithm with deep learning enabled hyperspec-tral image(HSI)classification(RDADL-HIC)technique.The proposed RDADL-HIC technique aims to effectively determine the HSI images.In addition,the RDADL-HIC technique comprises a NASNetLarge model with Adagrad optimi-zer.Moreover,RDA with gated recurrent unit(GRU)approach is used for the identification and classification of HSIs.The design of Adagrad optimizer with RDA helps to optimally tune the hyperparameters of the NASNetLarge and GRU models respectively.The experimental results stated the supremacy of the RDADL-HIC model and the results are inspected interms of different measures.The comparison study of the RDADL-HIC model demonstrated the enhanced per-formance over its recent state of art approaches. 展开更多

With environmental change and increased human activity,wild red deer(Cervus elaphus xanthopygus)populations and habitat area continue to decrease.Red deer is a main prey species of Amur tiger(Panthera tigris altaica).Factors affecting red deer winter home range in the Wanda montains of northeast China are not well understood.In this study,we aimed to better document red deer daily ranges to support conservation of red deer.A second objective was to develop a practical research method combining macro-and micro-technology for home range research on a variety of rare or endangered wild species.We collected 105 fresh fecal samples of red deer in three different periods during winter from December 2012 to March 2013 in the Wandashan region,Heilongjiang Province,China.Individual and sex identities were analyzed based on fecal DNA using microsatellite DNA.We used samples from deer farms for correction and validation of our identifications from field samples.We used a combination of molecular scatology,3S techniques(GPS),and direct observation to estimate winter daily range areas.Based on eleven microsatellite loci,we identified 18 individuals,10 females and 8 males,with a correction factor of 1.00 and sex ratio of 1:0.8.The mean(±SE)number of alleles was 5.1±0.41,and mean polymorphism information content was 0.63±0.03.Expected heterozygosity ranged from 0.46 to 0.81,with a mean of 0.69±0.03,and mean observed heterozygosity was 0.73±0.07.Sizes of mean daily ranges were 26.1±1.1 ha in December,89.3±1.6 ha in January,and 67.5±1.9 ha in March,indicating the following trend for daily range area:middle winter>late winter>early winter.Mean daily range area was insignificantly larger for males than for females.Estimated winter daily ranges were similar to those reported for Europe.Our combination of macro-and micro-technology proved useful for estimating winter home range areas of red deer. 展开更多

Six ultimate factors (forage abundance, horizontal sheltering class, distance from human disturbance,snow depth, tree coverage, and edge effect) of Red deer (Cervus elaphus) were investigated in eastern Heilongjiang Province during winter from 1988 to 1991. On the basis of analysis of field data, we evaluated winter habitat conditions of Red deer. The results showed as follows; the wintering habitat quality of Red deer in poplar-birch stands was excellent in the Wanda Mountains, and was moderate in shrub-woods and Korean pine seed stands.According to habitat index (HI) values, the habitat quality in poplar-birch stands (HI=0.8185) was superior to that in shrub-woods (HI=0.4825) and in Korean pine seed stands (HI=0.4385). The wintering habitat quality of Red deer in the Wanda Mountains was superior to that of Daning Forestry Region. According to the current situations of forestry areas in northeastern China, strengthening habitat management was important for the conservation and management of Red deer population in the next decades. 展开更多

Testosterone secretion may regulate the reproductive effort and the development of sexual traits,but it may also involve costs at the immunological and metabolic levels.However,the evidence for this trade-off in wild populations is scarce.Cortisol also plays an important role in mediating the reproductive and immune functions.In this study,we analyzed whether the endoparasite burden relates to hormonal levels(fecal testosterone and cortisol metabolites)and/or morphological sexual traits(size of the dark ventral patch,a trait that indicates reproductive effort in males)in male Iberian red deer.For this purpose,we sampled male red deer harvested during hunting actions in 2 types of populations in south western Spain that differed in structure,affecting the level of male–male competition for mates.We used coprological analyses to estimate the parasite burden mainly of gastrointestinal and bronchopulmonary nematodes and of protozoa,and assessed testosterone and cortisol metabolite levels from fecal pellets.We found a positive relationship of host parasitation with both testosterone levels and the size of the dark ventral patch,but these relationships depended on the intensity of male–male competition in the population,being only found under the high-competition scenario.These results are discussed under the hypothesis of the testosterone immunocompetence handicap,suggesting a cost at the immunological level,and,therefore,higher susceptibility to parasite infection in males that make a greater reproductive effort.However,this effect seems to be modulated by the social environment(male–male competition)that might lead to different optima in testosterone production and sexual trait development. 展开更多
