Sacred sites as habitats of culturally important plant species in an Indian megacity     

《Urban Forestry & Urban Greening》2018

Cultural ecosystem services related to urban green spaces contribute significantly to liveable cities. While previous studies highlight the intersection of cultural ecosystem services with societal values, spiritual or religious values associated with urban nature have received less attention. In India, as in other parts of the world, sacred sites are known for their biological richness, but analyses from urban sacred sites are largely missing. Based on a stratified random sampling approach, we analysed the cultivated and wild plant species assemblages of 69 sacred sites in the megacity of Bengaluru, India, in relation to biological and cultural features, and parameters related to the urban matrix and type of sacred sites (temple vs. katte). Unlike other urban studies, we found a dominance of native species in the cultivated and spontaneous species pools (121 species in total), with Ficus religiosa and Azadirachta indica as most frequently planted species. Culturally relevant species prevailed in the species pool (89%), with overlaps between religious (36%), medicinal (50%) and ornamental (62%) plants; only 11% of species were weeds. Urban matrix parameters (age of development, housing density) and size and type of sacred sites were related to differences in species assemblages. We identified key species for different classes of age and housing density, and for types of sacred sites. Our study demonstrates that urban sacred sites have an important potential in harbouring both native and culturally significant species that can support urban livelihoods in developing countries by a range of cultural and provisioning ecosystem services, including medicinal uses. As such sites are conserved by communities for spiritual or cultural beliefs, local biodiversity can be enhanced, e.g. by adapting management practices through community participation. This would strengthen the important contribution of sacred sites within the green infrastructure of rapidly growing megacities.  相似文献   

不同周龄大耳白兔血液生理生化指标的测定   总被引：5，自引：0，他引：5  

岳秉飞  程水生  杨果杰  吴福林  刘双环  靳彦华  左琴  程君生  邢瑞昌 《中国兽药杂志》2001,35(3):17-21

为了明确大耳白兔中国兽药监察所封闭群的生物学特性，对其血液生理生化指标进行了测定。选5、10及13周龄的雄兔和雌兔。空腹采血测定红细胞、白细胞等16项血液生理指标和血糖、总蛋白等16项生化指标。10周龄的红细胞数、白细胞数、红细胞压积和平均红细胞血红蛋白含量高于5周龄和13周龄，雌雄间血液生理指标无明显差异，血清丙氨酸转氨酶含量随着周龄的增加而升高，碱性磷酸则随着周龄的增加而下降。与日本大耳白兔相比，主要血液生理指标比较接近，丙氨酸转氨酸、白蛋白、尿素氮、直接胆红素等血液生化指标相近，其他指标有所不同。测定结果表明，该封闭群具有不同于日本大耳白兔（Slc:JW/CSK)的生物学特性。  相似文献   

Sensitivity,specificity, and predictive values of reagent test strip estimations of blood urea nitrogen     

Hill D  Correa MT  Stevens JB 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1994,23(3):73-75

Azostix-reagent-tests(R) strips (Ames, Miles, Inc., Diagnostic Division, Elkhart, IN) were used to measure blood urea nitrogen values in blood samples from 125 dogs and cats at the North Carolina State University, College of Veterinary Medicine. Results of the tests were compared with standard serum urea nitrogen results. Sensitivity, specificity, and negative predictive values were high (86.4, 90.3, and 96.5%, respectively). Positive predictive value was low, 65.5% of the dogs and cats with elevated blood urea nitrogen values were correctly classified as abnormal The test performs well when the prevalence of abnormal values is near 50%.  相似文献   

Prediction of breeding values for osseous fragments in fetlock and hock joints, deforming arthropathy in hock joints, and pathologic changes in the navicular bones of Hanoverian Warmblood horses     

K.F. Stock 《Livestock Production Science》2005,92(1):77-94

The results of a standardised radiological examination of 5928 Hanoverian Warmblood horses selected for sale at auction were used to predict relative breeding values (RBV) in the 23,662 horses included in the last four generations of the probands' pedigrees. The distribution of the RBV was investigated in the whole four-generation pedigree, in the probands and in those stallions that contributed at least three offspring to the probands. The RBV of the probands' sires were further compared with the officially published performance-based relative breeding values, i.e., total indices dressage (TID) and jumping (TIJ). The sires' level of dressage indices was considerably higher (mean TID=110) than of the jumping indices (mean TIJ=98). Total indices radiographic findings (TIR) were calculated for the sires with varying weighting given to the individual RBV. In each case, this resulted in a mean TIR of 99. Finally, total indices were derived from TIR and TID and/or TIJ in order to develop different selection schemes for all-purpose breeding and for breeding focused on dressage and show jumping. All breeding values under consideration increased by between 1% and 19% when radiographic findings were weighted with between 30% and 60% complementary to the corresponding performance parameters, and when only sires were selected with above average total indices. At the same time, the prevalences of the radiographic findings investigated here were lowered by up to 10% each. When only one radiographic finding was considered at a time, the maximum attainable response to selection was a 16-23% increase in the relative breeding values and a relative decrease in prevalences of radiographic findings of between 31% and 52%. The results of this study indicate that it is possible in horse breeding to consider simultaneously health and performance traits. Medical data should be included in the prediction of breeding values in order to improve the radiological status of today's riding horses.  相似文献

当代大学生思想变化规律的研究——基于蚌埠学院部分学生的问卷调查与访谈     

凌宏 《安徽农业大学学报》2015,(3):129-134

对当代大学生进行思想政治理论教育，必须深入研究当代大学生的思想变化规律。研究表明，当代大学生的思想变化呈现出如下规律：马克思主义为主流信仰，信仰比例随年级升高呈“V”形分布；政治认同感强，政治关注度与自身利益紧密相关；人生态度积极乐观，注意自我价值的实现；反对非诚信行为，期待诚信的社会环境。对以上规律的研究，有助于更有效地对当代大学生开展社会主义核心价值观教育。  相似文献

Shelf-Life of Spanish Mackerel (Scomberomorus commerson) from Northern Australian Waters     

《Journal Of Aquatic Food Product Technology》2013,22(4):63-79

Abstract

The shelf-life of Spanish mackerel caught by line fishing in Northern Australian waters was evaluated. Spiked fish were stored in ice either headed and gutted or left uncut and subjected to sensory, nucleotide, pH, histamine and microbial analysts and the rigor pattern recorded. There was little difference between the two product forms. Rigor in uncut fish lasted for 14 ± 9.8 hours and in headed and gutted fish for 19.6 ± 16.3 hours. Spanish mackerel retained good sensory quality for up to 14 days. The bacterial load reached 105 cfu/g by 18 days. K values were low for most of the storage time, < 40%. Histamine levels did not develop more than 10 mg/kg during storage. The pH of Spanish mackerel did not change much even though bacterial levels become high.  相似文献
