The Query of Suitable Areas for plantation and development of Taxus baccata L Species by Using GIS in Northern Iran

Abstract

Taxus baccata is a native species to the Caspian forests and is considered as the identification of these forests by some resources. The aim of this study was to understand the ecological characteristics of T. baccata in order to find suitable areas for its plantation in the Pone Aram preserve of Golestan province. Therefore, Multi-Criteria Evaluation (MCE) methods based on Analytical Hierarchy Process (AHP) were used. In this process at first the needed and effective natural indexes were used as 10 parameters. Then the final map of suitable areas for T. baccata plantation were produced based on Bolian and MCE models. According to the results, in Bolian method about 6218 ha of the total area of the study site (30554 ha) were estimated as suitable and semi suitable and 24336 ha were estimated as unsuitable for MCE model showed that about 2482 ha of the whole 30554 ha area of the study site is adequate for T. baccata plantation and 6181 ha is not adequate for T. baccata plantation. Regarding the results of the MCE and Bolian methods it has been concluded that for dynamic ecological parameters in delineation of suitable areas for T. baccata plantation the MCE weighting is more appropriate than Bolian. Using the results of this investigation it is possible to adequate areas for the presence of T. baccata and to execute a plan in order to facilitate the plantation of T. baccata in northern forests of Iran (watershed 88).

Empleo de sistemas de información geográfica para el análisis de problemas espaciales

“…Ejemplos de estos usos se pueden ver en [8], en donde se integra la teledetección y los SIG para hacer una evaluación del potencial de aguas subterráneas en el altiplano nariñense, por medio del análisis de diferentes variables obtenidas a partir de correlaciones con datos de reflectancia extraídos de imágenes LANDSAT, y en [9], en donde se utilizan las mismas herramientas (imágenes satelitales) para identificar afloramientos de notronita, aptos para la explotación económica en el departamento de Santander. Del mismo modo, en [10], por medio de la superposición de mapas de 10 índices, se elaboró un mapa final de áreas aptas para el cultivo de tejo común (Taxus Bacatá).…”

<b>Toxicity of the goji berry fruit associated with artificial excipients and dried without additives

“…Plant bioassays are appropriately sensitive and simple in monitoring the toxic effects at the cellular level of chemical compounds (Caritá & Marin-Morales, 2008;Campos-Ventura, & Marin-Morales, 2016). Among them, the root meristem of Allium cepa L. (onion) is considered in the scientific circle as an efficient bioassay for the initial screening of the genetic toxicity of chemical compounds due to the low number of chromosomes (2n = 16), which favors the detection of mitotic spindle or aneugenic defects, and disturbances in the cell proliferation index (Neves, Ferreira, Lima, & Peron, 2014;Bianchi, Mantovani, & Marin-Morales, 2015). It is a test system accepted internationally by research agencies as an instrument of evaluation with accurate sensitivity to analyze the cytotoxicity and genotoxicity of a substance of interest, since the results obtained often show satisfactory similarity to those obtained through animal testing systems and cell cultures (Herrero et al, 2012;Lacerda, Malaquias, & Peron, 2014;Tabrez et al, 2011;Bianchi et al, 2015;Campos-Ventura et al, 2016;Santana et al, 2016).…”
