Fig. 6 in Extremely Endangered Butterflies of Scattered Central European Dry Grasslands Under Current Habitat Alteration

Fig. 6. Species Distribution Models (MaxEnt) for three steppe butterflies, (a) C. briseis, (b) P. damon, (c) P. dorylas. Diagrams show BIOCLIM variables selected by jackknife procedure and their contribution to the model (explained variation) (x-axes: the value of the variable, y-axes: predicted values).The climatic niche is modelled for the last interglacial period (–130 ky), the glacial maximum (–21 ky), Younger Dryas (–12 ky), mid Holocene (–6 ky), current situation, and the future (2050) with an RCP4.5 climate change scenario. Purple colors show the suitability, including the least suitable training record (minimum training presence threshold), and orange colors the suitability of 90% of the training data (tenth percentile training presence threshold).The glacial sheet was adopted after Ehlers et al. (2011).
