Urban biodiversity

The most significant predictors of bug biodiversity in Los Angeles are proximity to the mountains and temperature stability throughout the year, according to a study we co-authored with Brian V. Brown of the Los Angeles Natural History Museum and colleagues at the University of Southern California and California State University. The project used data from the museum’s BioSCAN project, where volunteers across Los Angeles allowed insect traps to be installed on their property between 2014 and 2018. Arthropod species richness in Los Angeles. Black dots show locations where the BioSCAN project collected bugs between 2014-2018. The color scale shows the predicted number of species, with blue being the least rich and orange being the most rich. Map tiles by Stamen Design, CC BY-SA The analysis showed some surprising results. For instance, land values had little impact on the overall diversity of art...
