dc.description Invasive species have extensive negative consequences for biodiversity and ecosystem health. Novel species also drive contemporary evolution in many native populations, which could mitigate or amplify their impacts on ecosystems. The predatory zooplankton Bythotrephes longimanus invaded lakes in Wisconsin, USA, in 2009. This invasion caused precipitous declines in zooplankton prey (Daphnia pulicaria), with cascading impacts on ecosystem services (water clarity). Here, we tested the link between Bythotrephes invasion, evolution in Daphnia and post-invasion ecological dynamics using 15 years of long-term data in conjunction with comparative experiments. Invasion by Bythotrephes is associated with rapid increases in the body size of Daphnia. Laboratory experiments revealed that such shifts have a genetic component; third-generation laboratory-reared Daphnia from ‘invaded’ lakes are significantly larger and exhibit greater reproductive effort than individuals from ‘uninvaded’ lakes. This trajectory of evolution should accelerate Daphnia population growth and enhance population persistence. We tested this prediction by comparing analyses of long-term data with laboratory-based simulations, and show that rapid evolution in Daphnia is associated with increased population growth in invaded lakes.

Title Daphnia_r_field_data
Downloaded 3 times
Description This file corresponds to the field population growth analyses. Values of r were calculated for Daphnia pulicaria in Lake Mendota (ME) and Lake Monona (MO) for years before (pre) and after (post) invasion by Bythotrephes. The start date is the first day of sampling each year. For example, a sample conducted on February 3 would have a start date = 34. The start density refers to the estimated density of Daphnia on the start date. Sampling was performed by the North Temperate Lakes LTER. All data are available at: https://lter.limnology.wisc.edu/.

Title Multivariate_analyses
Downloaded 3 times
Description This file contains data used in the analyses of correlated ecological variables in Lake Mendota (ME) and Lake Monona (MO). We analyzed 10 variables in total, including Daphnia pulicaria body length. The time period is either before (Pre-invasion) or after (Post-invasion) invasions. The year is also specified. Sampling was performed by the North Temperate Lakes LTER. All data are available at: https://lter.limnology.wisc.edu/.

Title Phenotypic_size_trends_final
Downloaded 3 times
Description This file corresponds to the analyses of long-term phenotypic trends in Daphnia pulicaria. Status specifies whether Bythotrephes is present (Invaded) or absent (Uninvaded) from a lake. The time period is either before (Pre-invasion) or after (Post-invasion) invasions. The lake and year in which sampling was performed are also specified. AL = Allequash, BM = Big Muskellunge, CB = Crystal Bog, FI = Fish, ME = Mendota, MO = Monona, TB = Trout Bog. Sampling was performed by the North Temperate Lakes LTER. All data are available at: https://lter.limnology.wisc.edu/.

Title Pulicaria_age_clutch_size
Downloaded 3 times
Description This file contains data for the age at maturation (in days) and reproduction (clutches 1-4) of Daphnia pulicaria assessed in the common garden experiments. Each observation is specified by the generation (either 1 or 2), lake (of origin), status of the lake (Invaded or Not-invaded), experimental treatment (no predator-NP or predator-P), and the clone.
