Dem-Based Study of Habitat Characteristics of Torreya Fengqiao in Kuaiji Mountain, China
نویسندگان
چکیده
The habitat characteristics of Torreya were investigated based on high resolution DEM and remote sensing image. The distribution of Torreya was mapped by visual interpretation of IKONOS image. The landform and PCA analysis results showed that curvature, altitude, aspect and slope were found to be the dominant features controlling spatial distribution pattern of Torreya. A certain degree moisture related variables were proved to be the most important parameters to explain Torreya habitats preferences. The preferable habitat requirement for Torreya focused on those concave and southwest hillsides with elevation between 400 and 600 m and slope less than 30°.

Composition and Free Radical Scavenging Activity of Kernel Oil from Torreya grandis, Carya Cathayensis, and Myrica Rubra
In this study, we measured the composition and free radical scavenging activity of several species of nuts, namely, Torreya grandis, Carya cathayensis,and Myrica rubra. The nut kernels of the aforementioned species are rich in fatty acids, particularly in unsaturated fatty acids, and have 51% oil content. T. grandis and C. cathayensis are mostly produced in ZheJiang province. The trace elements...

متن کاملHabitat suitability modeling for wild goat (Capra aegagrus) in a mountainous arid area, central Iran
Wild goat (Capra aegagrus) is one of the most prominent mountain mammals dispersed in many habitats in Iran. However, few studies on the relationship between this species and its habitat have been conducted. This species is recognized as one of the main food source for highly endangered species such as cheetah and leopard. In this study which lasted from fall 2009 through summer 2011, seasona...
