Dr. Campbell presented a talk at the World Congress of Malacology in Pacific Grove, California in early August titled “Placing peculiar planorbids of the Pacific Northwest,” based on DNA analyses of some unusual freshwater snails.  The talk was co-authored with Dr. Charles Lydeard.  Dr. Campbell was also a co-author, along with Timothy Campbell and Dr. Lyle Campbell, of a talk at the same meeting titled “What’s dug up at Old Dock 2.”  This was presented by Timothy Campbell and discussed over 300 species of fossil shells that they found at a small quarry near Wilmington, NC.  The trip also provided an opportunity to visit the San Andreas Fault zone and see some non-mollusks such as condors and blue whales.

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.
