非本地入侵无尾两栖类Lithobates catesbeianus目前分布在巴西，特别是在大西洋雨林生物多样性热点地区。在这里，我们使用最大熵生态位建模算法（i）模拟该物种的北美本土地理分布和（ii）将该模型投影到整个巴西。在应用了一个平衡委员会和遗漏错误的阈值后，预测结果表明，主要在巴西南部和东南部发生的概率很高。我们还提出了第一份报告的物种已知分布在巴西，模型预测显示出良好的一致性。如果将预测图解释为描述L. catesbeianus，战略，以防止进一步入侵巴西应重点特别是在大西洋雨林生物多样性热点。
The non-native invasive anuran Lithobates catesbeianus is presently distributed in Brazil, especially in the Atlantic Rainforest biodiversity hotspot. Here, we use a maximum entropy ecological niche modeling algorithm (i) to model the North American native geographic distribution of this species and (ii) to project that model onto the whole of Brazil. After applying a threshold value that balances commission and omission errors, the projection results suggested high probabilities of occurrence mostly in southern and southeastern Brazil. We also present the first report on the species known distribution in Brazil, showing good agreement with model predictions. If the predictive map is interpreted as depicting invasiveness potential of L. catesbeianus, strategies to prevent further invasion in Brazil should be focused especially in the Atlantic Rainforest biodiversity hotspot.
