Cohen, M. B., Andow, D. A., Romena, A. M., Gould, F., Bentur, J. S.
Abstract: Using the F-2 screen methodology, we estimated the frequency of alleles conferring resistance to the CrylAb toxin of Bacillus thuringiensis Berliner in a Philippine population of the stem borer Scirpophaga incertulas (Walker). Evaluation of >450 isofemale lines for survival of F-2...

Hill, April L, Camilli, Sara, Dwaah, Henry, Kornegay, Benjamin, Lay, Christine A, Hill, Malcolm S
In many freshwater habitats, green algae form intracellular symbioses with a variety of heterotrophic host taxa including several species of freshwater sponge. These sponges perform important ecological roles in their habitats, and the poriferan:green algae partnerships offers unique...

Freshwater Sponges Have Functional, Sealing Epithelia with High Transepithelial Resistance and Negative Transepithelial Potential
Download2010
Leys, S.P., Goss, G.G., Adams, E.D.M.
Epithelial tissue — the sealed and polarized layer of cells that regulates transport of ions and solutes between the environment and the internal milieu — is a defining characteristic of the Eumetazoa. Sponges, the most ancient metazoan phylum [1], [2], are generally believed to lack true...
