ABSTRACT

At the Chennai Coast in Tamil Nadu, India, research is done. Finding out whether Marina Beach and Elliott's Beach are suitable for ecotourism is the study's main goal. For the research using the ecotourism suitability index methodology, land use, land cover, erosion, accretion, beach type, beach width, proximity to bus stop, proximity to train station, and suspended sediment load have all been taken into account. The suitability index of eco tourism is assigned into 4 (four) classes, which are: Class S1 (Highly suitable), Class S2 (Quite Suitable), Class S3 (Suitable with condition) and Class N (Not Suitable). Result of analysis indicates that coast area of Marina Beach and Elliots beach area comes in the class of Highly suitable (S1) by score total of 129 or 95.5 % and 116 or 85.9 % respectively. According to the research, Marina Beach has a sand feature as a land use land cover, 213 metres of beach width, good clarity (500 mg/L), is located 361 metres from a bus stop and 681 metres from a train station, has moderate erosion, and has not experienced any accretion. The beach type is white sand. Likewise, Elliots Beach has a sand feature as a land use land cover, with 222 metres of beach width, good clarity (600 mg/L), 642 metres from the bus stop, and 2351 metres from the railway station, which is high. There is moderate erosion and no accretion, and the sand is of the beach type, which is white. Marina beach has high tourism suitability index as compared to Elliot's beach. By considering marina beach, all the eight parameters are considered to be ne whereas Elliot's beach has far away accessibility this is the main reason for lowering the tourism suitability.

ABSTRACT

ObjectiveTo identify potential distribution areas for wild Panax ginseng cultivated under forest in Liaoning province, China, and analyze the ecological factors of spatial stratified heterogeneity affecting its ecological suitability and quality suitability. MethodWild Panax ginseng samples cultivated under forest were collected from 33 cultivation bases in Liaoning province. The Maxent maximum entropy model and ArcGIS were used to delineate the ecological suitability zones. Correlation analysis was performed on seven indicators and 110 ecological factors. Variables with significant correlation (P<0.05) were used to build partial least squares regression analysis models. A comprehensive quality zoning was conducted using the analytic hierarchy process (AHP). The geographic detector was employed to analyze the interactions among dominant ecological factors of spatial stratified heterogeneity affecting habitat suitability, quality suitability, and the ecological driving factors. ResultVegetation type was the most influential ecological factor for delineating the ecological suitability zones for wild Panax ginseng in Liaoning province. The main ecological suitability areas for wild Panax ginseng cultivated under forest were located in the northeast, east, and southeast regions along the line from Xifeng County to Gaizhou City. The comprehensive quality suitability of wild Panax ginseng cultivated under forest was highest in Kuandian County and Huanren County and gradually decreased to the northwest and southwest. Within the delineated regions, the suitability conditions and comprehensive quality of wild Panax ginseng cultivated under forest were primarily influenced by the interactions between radiation and precipitation factors. The content of the measured samples was significantly higher than the standards in the 2020 edition of the Chinese Pharmacopoeia, indicating the high overall quality of wild Panax ginseng in Liaoning Province. ConclusionAccording to the zoning and prediction results, areas in Fengcheng City, Xiuyan County, Zhuanghe City, Liaoyang County, Tieling County, Xifeng County, Gaizhou City, Haicheng City, and Dashiqiao City showed large potential distribution areas with high quality, making them highly promising for wild Panax ginseng cultivation. However, further experimental verification is required. The zoning results can provide insights for research on habitat suitability and comprehensive quality accumulation of wild Panax ginseng cultivated under forest, as well as guidance for the search for potential cultivation areas and industrial development of wild Panax ginseng in Liaoning Province.

ABSTRACT

Chuanxiong Rhizoma is a traditional Chinese medicinal material mainly produced in Sichuan and Chongqing of China. In recent years, the cadmium content in Chuanxiong Rhizoma produced in most of the genuine producing areas has exceeded the standard, which makes Chuanxiong Rhizoma difficult to be exported. To solve the problem of excessive cadmium content in soil, this study employed the MaxEnt model to simulate the potential geographic distribution of Ligusticum chuanxiong and evaluate important environmental factors, and re-plan its ecologically suitable areas based on the mineral distribution characteristics and soil cadmium pollution status. The results showed that the places suitable for L. chuanxiong growing covered an area of 335 523.69 km~2, mainly in central and eastern Sichuan, southern Shaanxi and most parts of Chongqing. Among them, the highly suitable areas of L. chuanxiong were mainly concentrated in Chengdu, Ya'an, Deyang, and Mianyang. Solar radiation, annual precipitation, and annual range of temperature were evaluated as important variables affecting the distribution of L. chuanxiong, with the contribution rates of 62.3%, 13.3%, and 6.8%, respectively. In addition, Qionglai county, Chongqing county, Mianyang city(Youxian district and Fucheng district), Qingchuan county, and Xinjin county were classified into the first-class ecologically suitable zone, covering a total area of 2 768.87 km~2. The se-cond-class ecologically suitable zone was even wider, involving such counties as Tongjiang county, Renshou county, Jianyang county, and Nanjiang county, and the total area reached 43 616.92 km~2. The re-planning of the ecologically suitable areas for L. chuanxiong has provided strong data support for the cultivation and resource development of L. chuanxiong and also new ideas for solving the problem of excessive cadmium content in L. chuanxiong.

ABSTRACT

This paper explored the ecologically suitable areas for growing Scutellaria baicalensis using Geographic Information System for Global Medicinal Plants(GMPGIS), to figure out the resource distribution of S. baicalensis worldwide and provide a scientific basis for its scientific introduction. A total of 349 S. baicalensis sampling sites were selected all over the world for GMPGIS-based analy-sis of the ecologically suitable areas with six ecological factors including annual average temperature, average temperature during the coldest season, average temperature during the warmest season, average annual precipitation, average annual relative humidity, and annual average illumination and soil type as the ecological indexes. The results demonstrated that the ecologically suitable areas for growing S. baicalensis were mostly located in the Northern hemisphere, and the suitable areas in the United States, China, and Russia accounted for 19.25%, 18.66%, and 13.15% of the total area worldwide, respectively. In China, the Inner Mongolia, Heilongjiang province, and Yunnan province occupied the largest proportions of the total area, namely 14.28%, 8.72%, and 6.18%, respectively. As revealed by ecological factors of each sampling site, S. baicalensis was resistant to low temperature but not to high temperature. The adaptive range of average annual precipitation is narrower than that of average annual air humidity. The suitable soils were mainly inceptisol, alfisol, and fluvisol. High temperature and rainy climate or excessively high soil bulk density was not conducive to the growth of S. baicalensis. The adoption of GMPGIS enabled to obtain areas with the greatest ecological similarity for S. baicalensis, which were reliable data supporting the exploration of resource distribution and reasonable introduction of S. baicalensis.

ABSTRACT

Abstract Aphids can harbor several secondary symbionts that alter important aphid-related ecological traits, such as defense against natural enemies, heat tolerance and host plant utilization. One of these secondary symbionts, Spiroplasma, is well known in Drosophila as a sex modulator and by interacting with the host immune system. However, little is known on the effects of Spiroplasma on aphids, such as its influence on the host immune defense against fungi and on host plant utilization. Aphid infections by Spiroplasma are known to be low and few aphid species were reported to be infected with this secondary symbiont, however aphids belonging to the genus Aphis in neotropical regions show high infection rates by Spiroplasma. Thus, we investigated the association of Spiroplasma with the tropical aphid Aphis citricidus through comparative biology experiments on two host plants with different nutritional value to the aphid. We demonstrate Spiroplasma induced no significant fitness costs to A. citricidus on either host plant as no changes in the fitness traits we assessed were observed. Spiroplasma infection only induced sutle changes on host longevity and fecundity. Therefore, we concluded Spiroplasma established a neutral interaction with A. citricidus under the selection pressure we tested, and argue on stress conditions that could better demonstrate the role of Spiroplasma in A. citricidus bioecology and associated costs involved.


Resumo Pulgões podem abrigar vários simbiontes secundários que alteram características ecológicas importantes, como defesa contra inimigos naturais, tolerância ao calor e utilização da planta hospedeira. Um desses simbiontes secundários, Spiroplasma, é estudado em Drosophila por alterar a razão sexual e interagir com o sistema imunológico do hospedeiro. No entanto, pouco se sabe sobre os efeitos do Spiroplasma em pulgões, como sua influência na defesa contra fungos entomopatogénicos ou na utilização da planta hospedeira, por exemplo. Spiroplasma foi identificado em poucas espécies de pulgão e geralmente em baixa densidade, contudo pulgões pertencentes ao gênero Aphis em regiões neotropicais apresentam altas taxas de infecção por Spiroplasma. Assim, investigamos a associação entre Spiroplasma e o pulgão neotropical Aphis citricidus por meio de biologia comparativa em duas plantas hospedeiras com diferentes valores nutricionais para o pulgão. Spiroplasma não causou custo adaptativo significativo para A. citricidus em ambas planta hospedeira. A infecção por Spiroplasma induziu apenas pequenas mudanças na longevidade e fecundidade do hospedeiro. Portanto, concluímos que Spiroplasma estabeleceu uma interação neutra com A. citricidus sob ausência de pressão de seleção. Entretanto, discutimos sobre condições de estresse que possam demonstrar o papel de Spiroplasma na bioecologia de A. citricidus e os possíveis custos envolvidos.

ABSTRACT

The wild plant Dactylorhiza hatagirea commonly used in Tibetan medicine. In recent years, it is on the verge of extinction due to improper excavation and habitat deterioration. Based on the literature review, and the meteorological and ecological data of Qinghai Province and data derived from the field survey, this study took the altitude, humidity index, annual average wind speed, monthly average sunshine, precipitation and temperature in growing season, soil type and vegetation type as the zoning indexes, and applied ArcGIS software for spatial superposition analysis. The results showed that the D. hatagirea was primarily found in the alpine meadow in the east and south of Qinghai Province. The overall suitable area was about 30 700 km~2. Taking Qinghai Lake as the boundary for reference, the area in the south appeared to be more suitable, while the area in the east appeared to be secondary in suitability. Henan County, Zeku County, Jiuzhi County and Banma County were the main suitable areas covering the expanse of 12 454 km~2. Through the field verification, such zoning results appeared to be accurate, precise and illustrative. The spatial distribution of ecological suitability provides the decision-making basis for the resource investigation, environment protection and comprehensive resource management. It also provides the empirical case for developing the interdisciplinary research method in the suitability study of medicinal plants.

ABSTRACT

Appropriate producing areas can guarantee the quality of Tibetan medicine, but research on the suitable ecological factors and suitable producing areas of Tibetan medicinal plants is scarce. This paper used the Geographic Information System for Global Medicinal Plants(GMPGIS) to analyze the ecological suitability of Tibetan medicinal plants nationwide. For the first time, the range of ecological factors and main soil types of Tibetan medicinal plants were extracted, such as the average annual temperature-19.4-24.2 ℃, annual average precipitation 17-4 088 mm, annual average sunshine 124.2-171.6 W·m~(-2). The main soil types were black calcareous soil, thin layer soil, chestnut soil and so on. Based on 337 sampling points, the largest ecological similarity area of Tibetan medicine across the country was obtained through ecological similarity analysis. In addition to Tibet and Qinghai provinces and Tibetan Autonomous Prefectures in Sichuan, Gansu, and Yunnan provinces, Jiuquan city and Linxia county in Gansu province, Panzhihua and Ya'an in Sichuan province, and Xinjiang, Inner Mongolia, and Shanxi provinces also had larger suitable cultivation areas. In addition, by analyzing the current situation of Tibetan medicine industry, the research pointed out that there were some problems such as unreasonable development and utilization of resources, lack of standards and norms, weak basic research and imperfect industrial system, and made corresponding countermeasures for sustainable development of resources, formulation of standards and specifications, promotion of medicine through science and technology, expansion of domestic and foreign markets, etc. This study provided the basis for guiding the rational layout of production bases, introduction and breeding of plant Tibetan medicine nationwide, laying the foundation for the scientific and standardized production of high-quality Tibetan medicine, clarifying the development direction of Tibetan medicine industry, and providing ideas for the development strategy of Tibetan medicine and other national medicine industry.

ABSTRACT

The fruit of Lycium barbarum L. (FLB) is a food and medicinal herb. Identifying suitable production regions for this plant would be beneficial to its cultivation and production. In this study, the Maxent model was used to identify ecologically suitable regions for the growth of L. barbarum L. In addition, based on its chemical composition, the suitable regions for production were identified by literature analysis and chemometrics. The results show that suitable regions for L. barbarum L. culture are mainly distributed in the northwest of China; suitable regions for the production of medicinal FLB were mainly concentrated in the district of Ningxia, Baiyin, Jiuquan and Zhangye of Gansu, and parts district in west of Inner Mongolia. All are the traditional production regions for FLB, which is consistent with the good quality of FLB produced in Ganzhou in ancient times, and the genuine medicinal materials of FLB produced in Zhongning of Ningxia today. The suitable regions for edible FLB were mainly distributed in northwest of Qinghai, Jiuquan and Zhangye of Gansu, as well as Aksu and Kizi sukirgiz of Xinjiang. The fruit type index of FLB in these regions is large, and the content of fructose and glucose in the fruit is high, which satisfies the edible commodity property. The study results lay a foundation for realizing the regional distribution and development of L. barbarum based on its different uses.

ABSTRACT

As an important part of clinical medication, the main function of processing of traditional Chinese medicine (TCM) is to reduce toxicity and increase efficiency. The key to the best clinical efficacy of TCM after processing lies in three aspects of moderation, adaptation and timeliness, namely " three suitability" theory. In recent years, scholars have done a lot of research under the guide of " three suitability" theory, fully explaining the scientific connotation of the theory, which greatly promoted the inheritance and innovation of TCM processing. In this paper, the basic connotation of " three suitability" theory was summarized, combining with a large number of modern research reports, the pharmacodynamics and composition changes of processed drugs were analyzed and discussed under the guide of " three suitability" theory. At the end of the paper, the authors proposed that we should not only systematize the traditional processing theories, but also use modern advanced technologies to explain the essence of traditional processing theories, and to innovate and develop new processing theories, promote the development of TCM processing discipline and the progress of TCM processing industry.

ABSTRACT

The suitable production area can guarantee the quality of Dai medicine, but the research on the suitable ecological factors and suitable production area of plant Dai medicine is relatively scarce at present. In this study, gmpgis was used to analyze the ecological suitability of Dai medicine in China. For the first time, the range of ecological factors and main soil types in the main distribution areas of Dai medicine were extracted, such as annual average temperature of 8.6-23.7 ℃, annual average precipitation of 1212-1881 mm, annual average sunshine of 149.7-157.4 W·m-2, the main soil types are strong eluvial soil, alluvial soil, high activity strong acid soil, etc. Based on 179 sampling points, through the analysis of ecological similarity, the largest ecological similarity area of plant Dai medicine in the world was obtained, mainly including China, Brazil, the United States, Myanmar, Laos and other countries. In China, it is mainly concentrated in the West and south of Yunnan, including Xishuangbanna Dai Autonomous Prefecture, Dehong Dai Jingpo Autonomous Prefecture, Pu'er City, Baoshan City and Lincang City, which are suitable for cultivation. In addition, by analyzing the current situation of Dai medicine industry, this paper summarizes the problems such as the lack of talents, the decreasing of Dai medicine resources, the limitation of cultural heritage, and the weakness of scientific research, and puts forward strategies such as training high-quality talents of Dai medicine, the investigation and protection of Dai medicine resources, promoting the collection and arrangement of Dai medicine data and ancient books, and strengthening the basic and applied research of Dai medicine Enter the development of Dai medicine. This study provides a basis for guiding the rational layout, introduction and breeding of plant Dai medicine production base, and lays a foundation for the scientific and standardized production of high-quality Dai medicine.
