Warming temperatures and rising moisture deficits are expected to increase the rates of background tree mortality–low amounts mortality (~0.5%–2% year?1), characterizing forest demographic processes in absence abrupt, coarse-scale disturbance events (e.g. fire). When compounded over multiple decades large areas, even minor increases <0.5% year?1) can cause changes communities carbon storage pot...
abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
Bacterial genome size reflects bacterial evolutionary processes and metabolic lifestyles, with implications for microbial community assembly ecosystem functions. However, to understand the extent of genome-mediated responses environmental selections, we require studies that observe distributions along gradients representing different conditions soil bacteria normally encounter. In this study, u...
BACKGROUND AND AIMS Anthropogenic depletion of stratospheric ozone in Arctic latitudes has resulted in an increase of ultraviolet-B radiation (UV-B) reaching the biosphere. UV-B exposure is known to reduce above-ground biomass and plant height, to increase DNA damage and cause accumulation of UV-absorbing compounds in polar plants. However, many studies on Arctic mosses tended to be inconclusiv...
