ABSTRACT:The ecotoxicological effects of Cr 2+ on germination and early seedling growth of six pulses were investigated. Seeds of these plants were exposed to seven different concentrations of Cr (0-3.2 mM). The results indicated that root elongation and coleoptile growth of six pulse plants were more sensitive than seed germination for measurement of the toxic of Cr 2+ pollutions. Different species show different levels of tolerance to Cr 2+ pollution. Lablab purpureus and Glycine max are the most sensitive to Cr 2+ , their germination percentage, root and coleoptile length were significantly lower than other tested species, by contrast, Lathyrus odoratus and Dumasia villosa are the most resist species, their germination and seedling growth almost were not influenced by Cr 2+ pollution significantly comparing the control. There were significantly negatively correlations between seedling growth and increasing concentration of Cr 2+ for Glycine max, Vigna radiate and Lablab purpureus. The significantly negative correlations between germination and increasing concentration of Cr 2+ were shown for Glycine max, Vigna radiate and V. angularis.

Mammals are key indicators for biodiversity conservation and management due to their high diversity, wide distribution range, and sensitivity to habitat changes. Recently launched by the Chinese Academy of Sciences, the Mammal Diversity Monitoring Network of Sino BON (Sino BON-Mammal) is a key member of the Biodiversity Monitoring Networks of Sino BON for the monitoring and inventory of terrestrial mammal resources in China. Firstly, this paper reviews several major advances in terrestrial mammal diversity observations in both China and other parts of the world. We then provide an overview of Sino BON-Mammal, including the major scientific goals, monitoring framework, methods, and data products. In addition, we also summarize some working advances of the Mammal Diversity Observation Network of Sino BON since 2011. This overview will be helpful for the development of national observation programs of mammal diversity in China.
