Aim Urban environments around the world share many features in common, including the local extinction of native plant species. We tested the hypothesis that similarity in environmental conditions among urban areas should select for plant species with a particular suite of traits suited to those conditions, and lead to the selective extinction of species lacking those traits. Location Eleven cities with data on the plant species that persisted and those that went locally extinct within at least the last 100 years following urbanization. Methods We compiled data on 11 plant traits for 8269 native species in the 11 cities and used hierarchical logistic regression models to identify the degree t..View full abstract
This paper is dedicated to our colleague Steven Clemants, who died during its preparation; we owe him a great deal. We thank Catherine Tait for providing the Adelaide data, Monique Hallet for helping to compile the Melbourne and Adelaide trait data, and Andrew Hipp and Myla Aronson for help with the Chicago data. This is a product of the Urbanization and Plant Functional Traits working group of the ARC-NZ Network for Vegetation Function. We acknowledge support of the Australian Research Council, The Commonwealth Environment Research Facility, and hosts of the workshops at which this work was conducted (the Australian Research Centre for Urban Ecology, the School of Botany and the Department of Resource Management and Geography, all at the University of Melbourne).
