title: Distribution of Viviparous American Fish Species in Eastern Europe on the Example of Gambusia holbrooki Girarg, 1859 and Poecilia reticulata Peters, 1859 in the Context of Global Climate Change
abstract: The potential distribution of tropical fish species in Eastern Europe—Gambusia holbrooki Girarg, 1859 (introduced for biological control) and Poecilia reticulata Peters, 1859 (aquarium species, found in wastewaters of big cities)—tends to be of particular interest in terms of global climate change. After GIS modeling of our own data and findings listed in the GBIF databases (2278 points for G. holbrooki and 1410 points for P. reticulata) by using the Maxent package and 18 uncorrelated variables
