This study assessed whether the toxicological effects of deoxynivalenol (DON) produced by Fusarium graminearum in rainbow trout ( Oncorhynchus mykiss ) are altered by the co-exposure to a mixture of toxins produced by Fusarium verticillioides (FU mix ). This FU mix contained fusaric acid and fumonisin B 1 , B 2 and B 3 . Four diets were formulated according to a 2 × 2 factorial design: CON-CON; CON-FU mix ; DON-CON; and DON-FU...

Soil has been identified as a possible carbon (C) sink to mitigate increasing atmospheric CO 2 concentration. However, several recent studies have suggested that the potential of soil to sequester C is limited and that soil may become saturated with C under increasing CO 2 levels. To test this concept of soil C saturation, we studied a gley and organic soil at a grassland site near a natural CO 2 spring. Total and aggregate‐as...
