Urbanization is one of the main causes of fragmentation and loss of habitat under native diversity, being the green areas a key space to shelter and protect species inside the cities. In aquatic ecosystems, subtle changes can lead to a rapid decrease in the species populations. Strengeriana fuhrmanni is a species endemic to west-central Colombia that lives in clear waters, and is sensitive to environmental changes. This work aimed to determine the effects of green areas and the urbanization process in the natural populations of S. fuhrmanni in the mountains of Manizales (Colombia) and whether different types of green areas serve as the refuges for the species. For the occurrence records, collections were carried out through active search in streams, and specimens from the biological collection were analyzed. An analysis of niche modeling and quantification of environmental spaces in the city was carried out, based on the occurrences of the species in the streams. The modeling showed that S. fuhrmanni was widely distributed in the streams of Manizales city; however, the fragmentation of the environment, through urbanization, restricted the population. Regarding the quantification of environmental spaces, this species is occupying less than 50% of its original area. Finally, we emphasize the importance of the green spaces for the remaining populations of S. fuhrmanni, as the streams are still conserved in these areas and provide conditions for their occurrence. Given the rapid urbanization process, it is important to study biodiversity inside these areas to understand how this process affects species, in special endemic ones.

城市化是本土多样性下栖息地破碎化和丧失的主要原因之一，绿地是城市内庇护和保护物种的关键空间。在水生生态系统中，细微的变化会导致物种数量迅速减少。Strengeriana fuhrmanni是哥伦比亚中西部特有的物种，生活在清澈的海水中，对环境变化很敏感。这项工作旨在确定绿地和城市化进程对S. fuhrmanni自然种群的影响在马尼萨莱斯（哥伦比亚）的山区以及不同类型的绿地是否作为该物种的避难所。对于发生记录，通过在溪流中主动搜索进行收集，并对生物收集的标本进行分析。根据河流中物种的出现情况，对城市环境空间的生态位建模和量化进行了分析。建模表明S. fuhrmanni广泛分布于马尼萨莱斯市溪流；然而，城市化造成的环境碎片化限制了人口。关于环境空间的量化，该物种占据的面积不到其原始面积的 50%。最后，我们强调绿地对S. fuhrmanni剩余种群的重要性，因为这些地区的溪流仍然得到保护，并为它们的发生提供了条件。鉴于快速的城市化进程，重要的是研究这些地区内的生物多样性，以了解这一过程如何影响特殊特有物种的物种。
