The use of environmental variables to explain the evolution of lineages has gained relevance in recent studies. Additionally, it has allowed the recognition of species by adding more characters to morphological and molecular information. This study focuses on identifying environmental and landscape variables that have acted as barriers that could have influenced the evolution of species and its close genera.Our results show that soil pH, isothermality, temperature seasonality, and annual precipitation have a significant phylogenetic signal for . Soil type and landforms are also relevant as ecological barriers that maintain the identity of species.The variables associated with the soil (pH) have influenced the evolution of and probably in other genera of Cactaceae. Additionally, is frequent in the piedmont and haplic kastanozems. Bioclimatic variables reinforce the recognition of and as independent species. Therefore, ecology can be considered as a factor to explain the high level of endemism in Cactaceae.
在最近的研究中，利用环境变量来解释谱系的进化已变得愈发重要。此外，通过在形态学和分子信息中加入更多特征，这也有助于物种的识别。本研究聚焦于识别那些作为屏障、可能影响物种及其近缘属进化的环境和景观变量。我们的结果表明，土壤pH值、等温性、温度季节性和年降水量对[物种名称]具有显著的系统发育信号。土壤类型和地形作为维持[物种名称]特征的生态屏障也很重要。与土壤相关的变量（pH值）影响了[物种名称]的进化，可能也影响了仙人掌科的其他属。此外，[物种名称]在山麓和薄层栗钙土中很常见。生物气候变量强化了对[物种名称]和[另一物种名称]作为独立物种的识别。因此，生态学可被视为解释仙人掌科高度特有性的一个因素。
