Fig. 1 in Maximum entropy niche-based modeling (Maxent) of potential geographical distribution of Coreura albicosta (Lepidoptera: Erebidae: Ctenuchina) in Mexico
Fig. 1. Model of potential distribution of Coreura albicosta with enhancement of the favorable climatic regions for this species, and superposition with the network of protected areas of México. Gray: lower probability of appropriate environmental conditions for distribution of the species. Light gray sections represent the decision threshold (0.2426) in which the grids are favorable for the distribution of the species. Darker sections inside light gray: areas with high probability of presence of the species. Black dots indicate the known distribution of the species. The protected areas are represented with a black line.

Fig. 3. Current (A and F) and future distribution models (B-E, G-J) for Haemadipsa rjukjuana in Korea. Dark gray represents over 0.5 MaxEnt value (suitable habitat) and light gray represents below 0.5 (unsuitable habitat). A is projected to the current climate conditions (2020), and F was built with the restricted spatial area between Heuksando Island and Gageodo Island. B-E are projections of the Maxent model to SSP585 of GISS-E2-1 climate scenarios by NASA and G-J were SSP585 of INM-CM4-8 scenarios by The Institute of Numerical Mathematics. B-E and G-J are respectively 2040, 2060, 2080, and 2100.

Prediction of the potentially suitable areas of Leonurus japonicus with the optimized MaxEnt model
<p><em><span>Leonurus japonicus </span></em><span>Houtt.</span><span> is a traditional Chinese medicinal plant with high medicinal and edible value.</span><span> Wild <em>L. japonicus</em> resources have been reduced dramatically in recent years. This study predicted the response of distribution range of <em>L. japonicus</em> to climate change in China, which provided the scientific basis for the conservation and utilization. In this study, 489 occurrence poin</span><span>ts</span><span> of <em>L. japonicus</em> were selected based on GIS technology and spThin package. The default parameters of the Maxent model were adjusted by using ENMeva1 package of the R environment, and the optimized Maxent model was used to analyze the distribution of <em>L. japonicus</em>. When the feature combination in the model parameters is hing and the regularization multiplier is 1.5, the Maxent model has a higher degree of optimization. With the AUC of 0.830 our model showed a good predictive performance The results showed that <em>L. japonicus</em> was widely distributed in the current period. The maximum temperature of the warmest month, the minimum temperature of the coldest </span><span>month</span><span>, the precipitation of the wettest month, the precipitation of the driest month and altitude were the main environmental factors affecting the distribution of <em>L. japonicus</em>. Under the three climate change scenarios, the suitable distribution area of <em>L. japonicus</em> will range-shift to high latitudes, indicating that the distribution of <em>L. japonicus</em> has a strong response to climate change. The regional change rate is the lowest under the SSP126-2090s scenario and the highest under the SSP585-2090s scenario.</span></p>
