Investigations on the density, diversity, and distribution of endophytic bacterial community associated with leaves of Cinnamomum camphora (L.) Presl. were carried out during three seasons using 16s rDNA high-throughput sequencing technology. Samples were collected from five species in Nanping (A, B, C, D, and E) and one from Fuqin (F) in the Fujian province, China in the months of April, July, and October (represented by 1, 2 and 3), indicating spring, summer, and early winter, respectively. Results from 16s rDNA sequences revealed 10,844,124 effective sequences. The highest OTUs (Operational taxonomic units) was highest in the A1 sample (1086), while the lowest was in C2 (509). Our observations showed that samples taken in October had the highest diversity of endophytes as indicated by the Shannon index (B3 = 5.3337), Chao1 (E3 = 1233.10), abundance-based coverage estimator (ACE) (A3 = 1764.72), and the Simpson indices of diversity (C3 = 0.1655) irrespective of the species. The order of the endophytes richness in the samples was April > July > October. The Ribosomal Database Project (RDP) classifier showed that the obtained sequences belonged to nine major phyla: Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria, Gemmatimonadetes, Acidobacteria, Planctomycetes, Chloroflexi, and Fusobacteria. Proteobacteria accounted for the highest proportion in each sample, ranging from 35.15% to 89.72%. These sequences belonged mainly to 10 orders: Rhizobiales, Clostridiales, Peseudomonadales, Burkholderiales, Bacteroidales, Enterobacteriales, Rhodocyclales, Sphingomonadales, Lactobacillales, and Bacillales. Also, other taxa with possible taxonomic statuses, which were unclassified, were present.

Urban garden landscape is a topic of great concern in the process of modern urban construction. It belongs to the landscape with vitality in the construction process. The plant landscape is also the product of the combination of economy, politics, culture and technology. The cold land plants belong to the only life-changing and cyclical elements in the garden design process. They use the seasonal changes of their distinctive features to realize the planning and design, which can effectively enrich the overall landscape effect. The seasonal changes of garden plants in cold regions mainly include space and color. The seasonal changes of color include leaves, flowers, fruits and branches, and the spatial characteristics are different periods of plants. In the process of realizing the garden configuration, it is important to comprehensively study the seasonal changes of plants, which can effectively improve the role of gardens. The study analyzes the influence of seasonal changes of garden plants on the landscape construction of garden space from three aspects: function, season and beauty. Therefore, the characteristics of seasonal changes of garden plants in cold regions are analyzed, so as to improve the rationality of landscape plant configuration in different seasons, and improve the level of garden landscape construction.

Samhita is considered as most important classical text of Ayurveda, used since 4th B.C. Samhita encompasses various concepts related to diseases and their treatment. Samhita offers different principles towards the maintenance of health status of whole mankind. These basic principles suggests us how to maintain good physical as well as mental status, rules of Samhita emphasizes different aspects related to diseases and their treatment. Ayurveda believe in prevention than cure therefore in this regards Ayurveda mentioned some pillars of life for healthy well being and Ahara is one of them. Ahara if consumed in proper manner then it will help to remain away from disease while inappropriate dietary pattern may lead pathological conditions. Considering Ahara as important aspect of healthy life further Ayurveda described termed “Viruddha-Ahara” which means incompatible foods responsible for pathological initiation. Incompatible food is one of the important concepts of medical science and it is believed that consumption of incompatible foods may lead various pathological manifestations. It is believed that opposite properties of wrong food combination, wrong processing, excess food consumption, consumption of food in wrong time and seasonal diversity may leads Viruddha-Ahara. Present article described ayurveda as well as modern perspective of Viruddha-Ahara/incompatible foods in a view to explore understanding of food originated diseases. Keywords: Ayurveda, Viruddha-Ahara, Incompatible foods, Samhita-Siddhant.

Land use change has a great impact in determining the diversity patterns of soil fauna. Adoption of any land use pattern significantly affects the soil structure and its physico-chemical characteristics, which often leads to the loss of biodiversity. Considering the collembolans as the key organism in the indicator shopping basket of soil environment, the response of Collembola communities under three different land uses represented by forest, vegetable and tea ecosystems was studied. Collembolans were sampled at monthly intervals using Tullgren funnel and identified by standard taxonomic keys. Diversity analysis and soil chemo-edaphic factors were studied to establish the impact of different land uses on Collembola communities. Five genera of Collembola viz., Cyphoderus, Entomobrya, Isotoma, Folsomia and Hypogastrura were recorded from the forest ecosystem whereas Folsomia was completely absent in vegetable ecosystem and the tea ecosystem soil was devoid of both Folsomia and Hypogastrura. Seasonal diversity and density of Collembola were recorded to be higher in the forest ecosystem indicating the presence of relatively stable habitats as compared to vegetable and tea ecosystems showing relatively disturbed habitats. Correlation studies between different chemo-edaphic factors and collembolan population revealed that the moisture and organic carbon content of soil had significant positive correlation during all the four seasons in all the ecosystems studied. Higher adoption of mechanical and chemo-centric agriculture depletes the available resources of the soil and makes it less habitable and conducive for the growth and sustenance of collembolans in vegetable and tea ecosystem as compared to forest. Appropriate landscape planning, land management strategies and developing proper methods of land use practices may pave the way for the improvement of collembolan diversity at landscape level.
