The northern Great Plains (NGP) of the United States has been a hotspot of West Nile virus (WNV) incidence since 2002. Mosquito ecology and the transmission of vector-borne disease are influenced by multiple environmental factors, and climatic variability is an important driver of inter-annual variation in WNV transmission risk. This study applied multiple environmental predictors including lan...

Weather and climate parameters and their effects on crops, is one of the most effective factors in yield increase. Agro-climatic studies could be used to determine the potential of various regions and the exploit these resources to the maximum possible extent. In this study, in order to evaluate the agricultural climate of spring canola cultivation in selected stations in Hamedan province, the ...

Net photosynthesis and stomatal conductance were measured in ten red spruce (Picea rubens Sarg.) saplings, growing near Ithaca, New York, throughout the early spring and late-fall growing periods. Gas exchange and daily minimum and maximum soil and air temperatures were also measured. Linear regression analysis showed that rates of net photosynthesis were positively correlated with both minimum...

The Israeli population of the cotton bollworm, Helicoverpa armigera (Hübner), undergoes a short-day, low-temperature pupal diapause and is also suspected of being a seasonal migrant in the eastern Mediterranean region. H. armigera were reared in the laboratory under several constant temperature and photoperiodic combinations which simulate average conditions encountered in the spring, summer, e...

The volatile organic compound (VOC) emission rates of Scots pine (Pinus sylvestris L.) were measured from trees growing in a natural forest environment at two locations in Finland. The observed total VOC emission rates varied between 21 and 874 ng g−1 h−1 and 268 and 1670 ng g−1 h−1 in southern and northern Finland, respectively. A clear seasonal cycle was detected with high emission rates in e...

Watermelon grafting is practiced in order to improve tolerance poor environments such as low temperature. This study was conducted investigate the effect of low-temperature tolerant bottle gourd (Lagenaria siceraria) rootstocks on growth and fruit quality watermelon semi-forcing retarding culture where plants were exposed or high Five accessions (FR79, IT207112, BG702, BG703, FRD22) with temper...

Spring applications require materials that possess a low Young’s modulus and high strength, in addition to having a lower alloying percentage for reduced costs. In this study, a new low-cost ¢-type titanium alloy with a lower alloying percentage than conventional ¢-type alloys was developed for spring applications using [Al]eq and [Mo]eq. The alloy is located in the near-¢ region and its ¢ tran...

cold tolerance is an adaptative mechanism that plants in temperate climates require to survive and grow in suboptimal temperatures.  exposed plant to low temperature produces a myriad of measurable changes in biochemical characters that are often highly correlated with plant cold tolerance.  a key element of cereal adaptation to cold is represented by the capacity for physiological adjustments ...
