Chlorpyrifos is a common surface water contaminant in California, USA. We evaluated five years of chlorpyrifos use and surface water monitoring data in California's principal agricultural regions. Imperial County and three central coastal regions accounted for only 10% of chlorpyrifos statewide use, but displayed consistently high aquatic benchmark exceedances (13.2%-57.1%). In contrast, 90% of...

Aim: Knowledge of the causes of deaths in Slovakia is lacking. This is significant because diet and lifestyle factors are different in central Europe compared to Western, Northern and Southern Europe. This study aims to discern trends of age-adjusted mortality rates caused by various diseases in relation to demographic factors. The aim of our study was to find certain statistical aspects includ...

This study identified single nucleotide polymorphism (SNP) markers associated with 15 complex traits in a breeding population of barley (Hordeum vulgare L.) consisting of 137 recombinant chromosome substitution lines (RCSL), evaluated under contrasting water availability conditions in the Mediterranean climatic region of central Chile. Given that markers showed a very strong segregation distort...

The age structures of populations of African annual Nothobranchius spp. were examined for the first time. Daily increments in sagittal otoliths of Nothobranchius furzeri, Nothobranchius kadleci, Nothobranchius orthonotus and Nothobranchius rachovii from southern and central Mozambique were used for age determination. Four hypotheses were tested: (1) timing of hatching is consistent with the cal...

drought stress is one of the important environmental factors reducing grain yield of plants in arid and semiarid regions. study the effect of water deficit stress on yield, water use efficiency and harvest index of sesame varieties, this experiment was conducted as a split plot based on a randomized complete block design with three replications, at agriculture and natural resources research cen...

Abstract Abnormal changes in temperature, precipitation, atmospheric carbon dioxide, or solar radiation are examples of climate change that may affect irrigation water demand. Studies show an increasing trend the earth’s surface with decreasing trends rainfall. With most studies focused on predicting extent change, fewer developing appropriate response strategies. This paper aims to propose a s...
