observed species指数，chao指数和ace指数区别为：性质不同、变化不同、引入变量不同。一、性质不同 1、observed species指数：observed species指数表示该样品中含有的物种数目。2、chao指数：chao指数估算样品中所含OTU数目的指数。3、ace指数：ace指数评估样本中物种组成的丰富度和均匀度。二、变化不同 1...
aMost popular composite indices of well-being constructed by the United Nations Development Programme (UNDP) such as the Human Development Index (HDI), Human Poverty Index (HPI), and Genderrelated Development Index (GDI) follow this basic sequence. 正在翻译,请等待...[translate] ...

The Important Value Index (IVI) of an individual plant was identified to know the relative dominance. The plant types colonized was influenced by landscape orientation i.e., aspect. The pullout resistive force of different grass species was ranged between 6 to 49 Newton. The pullout resistive ...
Inferred core bioclimatic ranges of species along global temperature and moisture index gradients and across continents follow the known global distribution of tree diversity such as its highest levels in moist tropical forests and the 'odd man out' pattern of lower levels in Africa. To demonstrate ...
The accurate mass data shouldpreferably have an error less than 5 ppm. The calculations are based on the neutral mass so all the ion adducts for the cations are removed or the observed anions corrected for the loss of a proton or ionadducts before calculating the index [6,7].RMW...
Changes in the production of hydroxyl radicals, used as an index of tissue production of reactive oxygen species (ROS), were determined by measuring the conversion of salicylate to 2,3-dihydroxybenzoic acid. Low levels of salicylate (0.1mM) in artificial perilymph were applied by perfusion of ...
