Dr. Campbell is a co-author (doing the DNA work) of an article: Lyubov E. Burlakova, David Campbell & Alexander Y. Karatayev. 2019. “Status of rare endemic species: Molecular phylogeny, distribution and conservation of freshwater molluscs Truncilla macrodon and Truncilla cognata in Texas”. Malacologia 62(2):345-363.  It’s an ecological and DNA sequence analysis of mussels from central and southern Texas.  Our data confirm that Truncilla cognata is a distinct species found only in the Rio Grande system, making it a high conservation priority, especially as it may be affected by border activity and water use.  Similarly, T. macrodon is confined to central Texas, different from the more widespread species in the Mississippi River drainage and nearby rivers. 


Also, Dr. Campbell is the author of the chapter “Family Semisulcospiridae” in the book Freshwater Mollusks of the World: A Distribution Atlas, edited by Charles Lydeard and Kevin Cummings, which is forthcoming from Johns Hopkins University Press.  The Semisulcospiridae is a family of snails found in northwestern North America and eastern Asia.  Some species are imperiled; others are important hosts of parasites.
