Various plant indexes are used or recommended for bioindication. However, the nonmonotonic dose-response dependences (hormesis and paradoxical effects) of these indexes are insufficiently explored upon exposure to pollution. We studied the dependences of these Betula pendula indexes on the intensity of motor traffic pollution. Regression analysis did not reveal any dependence of chlorophyll and...

For the monitoring and management of forest resources, main index is stand volume, which determined on basis tree diameter, height, number trees per hectare three-dimensional distribution. The development in dynamic driven by random phenomena. In this study, potentially available area, height are described mixed-effect parameters Gompertz-type diffusion process. A normal copula function used to...

Recent studies have shown that nanomaterials, including carbon nanotubes, are associated with a wide range of effects on living organisms, from stimulation to toxic effects. Plants an important object such research, which is the potential use nanomaterials in agriculture and environmental protection. At same time, specific mechanisms formation plant resistance nanotubes remain not fully underst...
