My newest publication on the current state of biological control of water hyacinth in the Sacramento-San Joaquin River Delta is hot off the press! (Journal of Biological Control)
Here is the link to the publication, and you can read it and download it free of access for 50 days! (after that just shoot me an email and I’ll send you a copy if you are interested).
This manuscript is a product from some of my work, and collaborations, from the past year that I described a bit in an earlier blog post .
I could not have done this without the help and mentorship of many folks at the USDA, including Kent McCue, Patrick Moran, and Paul Pratt, USDA Research Leader and a specialist in the biological control of aquatic weeds. There were also some very amazing technicians at USDA including Matt Perryman, Caroline Nunn, Anna Beauchemin, Ethan Grossman, and Clayton Sodergren who put a lot of work into this research as well.
Below is a figure (ArcGIS work by Clayton Sodergren) highlighting the spatial variation in peak weevil densities (Aug-Nov. 2015) in the Delta, as well as demonstrating the variation in the abundance and distribution of the two weevil species (Neochetina bruchi and N. eichhorniae).
