Abstract

Abstract Urban forests are responsible for a lot of benefits, and can be used as a tool to ex-situ conservation of native species. Our study investigated a public urban forest aiming to provide subside to management projects in order to allow the accurate fulfillment of social, aesthetic and ecological functions displayed by trees. Our survey was conducted in 6 public squares and 5 gardens in the Jardins neighborhood. We classified the trees according to their phytogeographic origins and seed dispersal habit. The Shannon-Weaver (H’) index, Simpson’s dominance (D’) and Pielou’s equability (J) were determined. A total of 507 individuals were sampled, located in 12 botanical families and 29 species, and 13 of them were classified as native and 16 as exotic. The family with higher species richness and number of species was Fabaceae (36%). Regarding the seed dispersal syndrome, the most representative was zoochory (52%). The ecological index showed medium species diversity (H’=2.2284), high dominance (D’=0.7899) and medium number of individuals (J) 0.6552. Although the Jardins neighborhood was planned, the urban forest in this area still needs improvement; such as incentive measures that can promote biodiversity and the application of ex-situ conservation.

生物多样性社区:一种迁地保护工具

摘要城市森林有很多好处，可以作为迁地保护本土物种的工具。我们的研究调查了一个公共城市森林，旨在为管理项目提供资金，以便准确实现树木所表现出的社会、美学和生态功能。我们的调查在Jardins社区的6个公共广场和5个花园进行。我们根据树木的植物地理起源和种子传播习惯对其进行了分类。确定了Shannon-Waver指数（H'）、Simpson优势度（D'）和Pielou方程（J）。共采样507个个体，分布在12个植物科和29个物种中，其中13个被归类为本地物种，16个被归类于外来物种。物种丰富度和种数较高的科为蚕豆科（36%）。关于种子传播综合征，最具代表性的是动物感染（52%）。生态指数显示物种多样性中等（H’=2.2284），优势度高（D’=0.7899），个体数中等（J）0.6552。尽管Jardins社区已规划，但该地区的城市森林仍需改善；例如可以促进生物多样性的激励措施和迁地保护的应用。

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.
