Figure 4 in Palaeoclimatic distribution models predict Pleistocene refuges for the Neotropical harvestman Geraeocormobius sylvarum (Arachnida: Opiliones: Gonyleptidae)

Figure 4. Marginal response curves for the most relevant variables used to model the distribution of Geraeocormobius sylvarum. Curves depict average values (black curve) and ± SD (grey curves) of the 50-replicates run; vertical dotted lines represent the lowest and highest values in the record set, i.e. they delimit the empiric range of the variable. Above: bc18, precipitation of warmest quarter (critical values: 390–560 mm) and bc7, temperature annual range (critical values: 21°C–24.3°C); bottom: bc14, precipitation of driest month (critical value:>42 mm) and bc9, mean temperature of driest quarter (critical values: 14.3°C–18.9°C, peak at 17.3°C). The y-axis displays the logistic probability of presence; horizontal line indicates the 0.50 value.
