When looking around outside, many people see reasons to worry about the environment. Often what they notice are effects of pollution and climate change, which can be harmful people, wildlife, ecosystems where live. Understanding condition all living non-living things in an ecosystem is important for maintaining a healthy But collecting information on every element takes time effort not always p...

Gonabad located at Khorasan Razavi and coordinates 580 30’ N 34o 35’ E. The highest point of the zone belongs to Peak of Siah Mountain (height of 2,863 meters above sea level) and the lowest place has height of 810 meters above sea level, which is located in North West in salt desert. The mean temperature of the warmest and coldest of year is 29.3 and 3.9 respectively. Mor...

BACKGROUND AND AIMS Adventitious sprouting from the hypocotyle and roots in monocarpic herbs has been confirmed in previous experimental studies as a means to avoid bud limitation after severe injury in annual and biennial plants. Data regarding the role of adventitious sprouting in natural populations, however, were lacking. The aim of the present study was to assess whether adventitious sprou...

there are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of china lands which are facing serious problem of desertification. theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofnortheast china, north central china and most of northwest china. biological methods are theultimate way for drift sand stabilization and a fu...

T-2 toxin, a trichothecene mycotoxin, is considered to be one of the most toxic compounds that are produced by molds, particularly the Fusarium species. Fusarium species have been recognized as a great agricultural problem. They occur worldwide on a variety of plant hosts and cereal grains. The aim of this study was to investigate T-2 toxin-induced liver injury using in situ perfused rat liver....

Soil disturbance is recognized as an important driver of biodiversity in dry grasslands, and can therefore be implemented as a restoration measure. However, because community re-assembly following disturbance includes stochastic processes, a focus only on species richness or establishment success of particular species will not inform on how plant communities respond ecologically to disturbance....

As the climate changes, some species within existing plant communities will become maladapted to local conditions. Immigration of climatically-suited species is unlikely to keep pace. This study investigated methods of using 1) community similarity between current and projected future plant communities as an indicator of ecosystem stress due to climate change, and 2) geographic distance to clim...
