Contribution of the five most important explanatory variables to the variation in survival ratios of Listeria monocytogenes.

The respective contributions of each variable were calculated by taking into account all the significant variables in the model using partial redundancy analyses (significance assessed with 1999 data permutations).BCSR : Basic Cation Saturation Ratio, CEC : Cation-Exchange Capacity, Sp. DistV : Spatial Distance correspond to the spatial vector x from the PCNM analysis, Alexch : exchangeable aluminum, Caexch : exchangeable calcium, Mnexch : exchangeable manganese, CaCO3tot : Total calcareous content,Tempmonth : mean temperature per month.
