| Abstract: | Wolbachia endobacteria are commonly associated with a varietyof arthropod species as hosts and induce known changes in theirhosts’ life-history traits. Despite exhibiting severalWolbachia-like life-history traits, and despite being a commonmodel organism, the zooplankton Daphnia pulex has not been formallytested for infection with Wolbachia. Among 203 isolates exhibitinga range of life-history phenotypes, we found no evidence ofWolbachia. This leaves the genes of D. pulex as the most likelycause of its own life-history traits. |
