reference evapotranspiration is an important parameter in irrigation systems' design that is evaluated through either direct (lysimeter) or calculated method (empirical equations). when there is a lack of lysimeters' data, penman monteith fao method could be employed as a standard method for evaluating the other empirical methods' results. in this research, 13 year evaporation pa...

b a ckground: the present study aimed to demonstrate the seasonal activities of ixodes ricinus at the pasture level and on the host. m e t hods: a vast pasture in amol countryside (mazandaran province, iran) which had the potential for a considera- ble number of cattle and sheep to graze was chosen. tick sampling from the skin of 130 cattle and 130 sheep were collected every month interval. sim...

Microbial uptake of dissolved phosphorus (P) is an important lever in controlling both microbial production and the fate and cycling of marine P. We investigated the relative role of heterotrophic bacteria and phytoplankton in P cycling by measuring the P uptake rates of individual microbial groups (heterotrophic bacteria and the phytoplankton groups Synechococcus, Prochlorococcus and picoeukar...
