Fossils of ostracods, a type of aquatic bivalve crustacean, typically include only shells, says David J. Schaefer and Miura (1990) similarly reported a reduction in fecundity of mixed populations of cladocerans and ostracods at pyriproxyfen exposure levels of 31 nM (Schaefer and Miura 1990). The paired outer shells of fossilized darwinulid ostracods turn up by the thousands in ancient lake sediments around the world, so these species offer the unusual advantage of a potential asexual with an abundant fossil record. |
