Understanding the response of terrestrial ecosystems to future climate changes would substantially contribute scientific assessment vegetation–climate interactions. Here, spatiotemporal distribution and dynamics vegetation in China were projected compared based on comprehensive sequential classification system (CSCS) model under representative concentration pathway (RCP) RCP2.6, RCP4.5, RCP8.5 ...
the purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof nodushan, yazd. the plant species cover and the environmental variables were measured at 9 sites. soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. vegetation was classified using twowayindicator species analysis (twinspan). data was analyzed u...
The ongoing changes in vegetation spring phenology in temperate/cold regions are widely attributed to temperature. However, in arid/semiarid ecosystems, the correlation between spring temperature and phenology is much less clear. We test the hypothesis that precipitation plays an important role in the temperature dependency of phenology in arid/semiarid regions. We therefore investigated the in...
Ross River virus (RR) is a mosquito-borne arbovirus responsible for outbreaks of polyarthritic disease throughout Australia. To better understand human and environmental factors driving such events, 57 historical reports on RR outbreaks between 1896 and 1998 were examined collectively. The magnitude, regularity, seasonality, and locality of outbreaks were found to be wide ranging; however, anal...
One of the areas that show most visible effects human-induced land alterations is also world’s essential resource: water. Decision-makers in arid regions face considerable difficulties providing and maintaining sustainable water resource management. However, developing appropriate straightforward approaches for quantifying use arid/hyper-arid still a formidable challenge. Meanwhile, better know...
Role of governments in expansion of household rainwater harvesting systems: introduction to experiences of some countries Vahedberdi Sheikh Associate Prof, Gorgan University of Agricultural Sciences and Natural Resources Received: 2019/09 Accepted: 2020/01 Abstract Sustainable utilization and conservation of natural resources has a key importance in intelligent development. To attain sustain...
Livestock production by transhumance rearing systems is the major land use and a source of livelihood in most areas of the arid, semiarid, and arid temperate agro-ecological zones of Asia. It is perhaps the best way of exploiting these pastures economically. Lack of feed is the major constraint to improving livestock production during winter and early spring, as the temperatures are extremely l...
the objective of this research was to investigate the effects of deficit irrigation on physiological and agronomic terms of eggplant to maximize the water use efficiency (wue) without affecting the final yield and fruit quality parameters under arid environment. therefore, two field experiments were conducted at two different sites: ghor al-safi, jordan valley and sail al-karak, karak valley, ka...
City and human are two different human-made and natural systems which has an effect on each other. The formation of a residence depends on the climatic conditions. Construction of a residence shows that people have adapted themselves and their activities to it; while the climatic conditions play an important role in comfort in human environments. Thus, the buildings and environmental spaces sho...
