Alternative models for <i>Batrachochytrium dendrobatidis</i> infection loads (in logarithm) in six different sites.

<p>The first six models include the average minimum and maximum water temperature (T) in six different time spans prior to tadpole sampling (i.e., two, five, ten, 15, 22 and 30 days), taking into account other three predictor terms: tadpole abundance (abund), tadpole development (develop) and site. Sample size is 66 (six sites x 11 months). AICc: AIC corrected for small sample sizes. W_i: model weights. W_t / W: quotient of strength of evidence dividing the weight (W_t) each model containing both maximum and minimum temperatures with the model without temperatures (W). Figures below Min T, Max T, tadpole abundance and development are standardized regression coefficients (β) obtained in mixed general linear models (β values inform about the magnitude and sign of the partial relationships of the predictor variables). Weighted averages: multimodel inference of standardized β regression coefficients considering the model weights W_i. The AICc figure for the null model (i.e., not including any effect) is 208.04.</p><p>Alternative models for <i>Batrachochytrium dendrobatidis</i> infection loads (in logarithm) in six different sites.</p

Average minimum water temperature and infection load of <i>Batrachochytrium dendrobatidis</i>.

<p>Partial residual plot illustrating the influence of average minimum water temperature two days before tadpole sampling, on <i>Batrachochytrium dendrobatidis</i> infection load (in logarithm) of <i>Alytes obstetricans</i> tadpoles from six different sites. Sample size is 11 months for each site. The residual plot shows the relationship between minimum temperature and <i>Bd</i> load given that the other two independent variables are also in the model (see with temperature-2 days in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120237#pone.0120237.t001" target="_blank">Table 1</a>), therefore, partialling out their effects. The inner panel shows the modeled relationship between <i>Bd</i> load (average number of zoospores per tadpole) and average minimum temperature two days before sampling.</p

Prevalence and infection load of <i>Batrachochytrium dendrobatidis</i>.

<p>Prevalence (left) and infection load (right; in logarithm scale, GE, mean +/- SE) for populations of <i>Alytes obstetricans</i> tadpoles in six different sites throughout 12 months in each site. Monthly average minimum and maximum water temperature are shown in blue and red respectively.</p
