A brief historical essay is presented on the leading Russian scientific school plant environmental physiology, which has for over 60 years been studying issues of adaptation to adverse factors (low and high temperatures, excessive lighting, heavy metals, etc.). The tells about main sources prerequisites its foundation, development this key results achievements since 1970. most important among l...

Global warming is a significant threat to the sustainability and profitability of dairy sector, not only in tropical or subtropical regions but also temperate zones where extreme summer temperatures have become new challenging reality. Prolonged exposure cows high compromises animal welfare, increases morbidity, suppresses fertility, resulting devastating economic losses for farmers. To counter...

Nickel is  an essential microelement for plant growth, but upper levels of this element serve as heavy metal  which create toxic effects on plants and human. Application of mineral nutrition is a useful strategy for overcoming of this serious problem.  In order to investigate the effects silicon nutrition on growth and physiology indices of basil (Ocimum basilicum L.) under nicke...

Abstract During normal cellular activities Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) are produced. In addition to beneficial functions they play a critical role in cell death and prevent apoptosis. Every cell is equipped with an extensive antioxidant defense system to combat the excessive production of active radicals. Oxidative stress occurs with destruction of cellu...

Salinity is a major environmental factor limiting plant growth and crop productivity. Therefore many studies had been done to minimize the stress effects caused by salinity in agriculture and plant physiology. To access the effect of methyl jasmonate and salinity on peppermint, experiment was conducted as factorial based on a randomized complete design (CRD) with three replications. In this res...

The sublethal effects of high predation risk on both prey behavior and physiology may have long-term consequences for prey population dynamics. We tested the hypothesis that snowshoe hares during the population decline are chronically stressed because of high predation risk whereas those during the population low are not, and that this has negative effects on both their physiology and demograph...
