West Nile virus (Flaviviridae: Flavivirus) is a serious infectious disease that recently spread across the North America continent. A spatial analysis tool was developed on the ArcMap 9.x platform to estimate potential West Nile virus activity using a spatially explicit degree-day model. The model identifies when the virus Extrinsic Incubation Period (EIP) is completed within the vector longevi...
Abstract Urea is a renowned nitrogen (N) fertilizer widely used in plant N nutrition owing to its high concentration (46%). The effect of the application rate on ammonia (NH 3 ) emission into environment and soil properties yet be unraveled. NH from sandy loam amended with manure compost (T1: 5000 kg ha −1 urea at different rates (100, 200, 400 designated as T2, T3, T4, respectively) replicatio...
Understanding of effects of soil temperature and soil moisture on soil respiration (Rs) under future warming is critical to reduce uncertainty in predictions of feedbacks to atmospheric CO2 concentrations from grassland soil carbon. Intact cores with roots taken from a full factorial, 5-year alpine meadow warming and grazing experiment in the field were incubated at three different temperatures...
