Abstract

Abstract Biotic homogenization is a global phenomenon, mainly in urban areas where exotic species are dominant, contributing to the loss of native biodiversity. Gardening native flora to promote local biodiversity is becoming a conservation practice in urban settings. Therefore, in this study, we analyzed the representation of the Chilean native flora in the Chilean and international ornamental flower seed market to know which native plant seeds are sold. We found that native seed are absent in the local market and that the totality of seed supply in the market corresponds to species of exotic origin, mainly from the Palearctic region (43%). However, surprisingly, many Chilean flower seeds are traded in the international market (approximately 6% of the total Chilean flora). This lack of availability of native seeds for local consumers constitutes a bottleneck for ecological restoration initiatives. It is consistent with the greater abundance of exotic species in urban green areas and supports the hypothesis of biocultural homogenization.

生物同质化在智利本地植物观赏种子的可用性

生物同质化是一种全球性现象，主要发生在外来物种占主导地位的城市地区，导致本地生物多样性的丧失。种植本地植物以促进当地生物多样性正在成为城市环境中的一种保护实践。因此，在本研究中，我们分析了智利本土植物在智利和国际观赏花种子市场上的代表性，以了解哪些本土植物种子在销售。我们发现本地种子在当地市场上是缺失的，市场上的种子供应总量对应于外来物种，主要来自古北地区(43%)。然而，令人惊讶的是，许多智利花卉种子在国际市场上交易(约占智利总植物群的6%)。当地消费者无法获得本地种子，这构成了生态恢复行动的瓶颈。这与城市绿地中外来物种的丰富度一致，支持了生物栽培同质化的假设。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
