Previous work by ARMI scientists have shown the important impact of invasive crayfish (Procambarus clarkii) on endangered and threatened amphibian species in southern California (onlinelibrary.wiley.com/doi/abs/10.1111/cobi.13198 ). New published research has shown that these non-native predators may increase disease vectors (e.g. mosquitoes) through predation on native predators of these vectors such as dragonfly nymphs (www.usgs.gov/center-news/invasive-crayfish-increase-number-mosquitoes-southern-california-mountains). This work has also been highlighted in a recent National Geographic report on the study (www.nationalgeographic.com/animals/2018/08/swamp-crayfish-crawfish-mosquitoes-disease-animals/).
