Partaking in this grisly feast are the larvae of a parasitoid wasp, Copidosoma floridanum. Like other wasps, Copidosoma are haplodiploid: Fertilized eggs produce females; unfertilized eggs become males. These wasps are also polyembryonic: Eggs split to produce many clonal embryos.

One of these criteria remains unmet: the repeated demonstration of the presence of C trachomatis on flies. The aut...
Surface runoff is one of the main causes of erosion and loss of soil fertility, sedimentation in reservoirs and reduction of river water quality.

Hydrological models are simplified views of the actual watershed systems that can help study watershed functions in response to various inputs, and underst...
