The purpose of our investigation was to clarify the effects of agriculture on the process of loss of litter at the periphery of a farmland. This study revealed the generation process of an ecologically unusual phenomenon that is observed around cropland in semi-arid regions. We hypothesized that the vegetation around a farmland cannot supply plant litter to the ground surface because the ecolog...

Climate is a driver of terrestrial ecosystem carbon exchange, which is an important product of ecosystem function. The Qinghai-Tibetan Plateau has recently been subjected to a marked increase in temperature as a consequence of global warming. To explore the effects of warming on carbon exchange in grassland ecosystems, we conducted a whole-year warming experiment between 2012 and 2014 using ope...

Aim: We aimed to investigate the prevalence and molecular characterization of rabies virus (RABV) from wild and domestic animals in Mongolia during 2008-2010. Materials and Methods: Brain tissue samples were collected from 24 rabid animals in Zavkhan, Omnogovi, Tov, Dundgovi, Govi-Altai, Selenge, Ovorkhangai, and Khentii provinces in Mongolia. Herein, samples were included from 13 domestic anim...

The Patagonian steppe is an immense, cold, arid region, yet phylogeographically understudied. Nassauvia subgen. Strongyloma is a characteristic element of the steppe, exhibiting a continuum of morphological variation. This taxon provides a relevant phylogeographical model not only to understand how past environmental changes shaped the genetic structure of its populations, but also to explore p...

Abstract Nonnative plant invasions can have devastating effects on native communities; conversely, management efforts nontarget and deleterious impacts desirable plants. In the arid sagebrush steppe rangelands of western United States, nonnative winter annual species affect forage production biodiversity. One method proposed to control these is suppress soil seedbank using preemergent herbicide...

the purpose of this study was to investigate vegetation dynamics and range conditions considering the climatic conditions and soil properties in doolat gharin in the south of isfahan province of an area equal to 25 square kilometer. for this purpose, after determining vegetation types and associated species, the type of rangeland utilization, grazing season, the type of livestock and other rele...
