Jesse Ausubel to receive 2022 Nierenberg Prize

Jesse Ausubel will be honored with the 2022 Nierenberg Prize for Science in the Public Interest. This award is presented annually by Scripps Institution of Oceanography at UC San Diego and the Nierenberg Family to honor the memory of William A. Nierenberg, an esteemed physicist and national science leader who served Scripps Oceanography as director for two decades. Previous awardees include atmospheric scientist Warren Washington, biochemist and Nobel Prize winner Jennifer Doudna, filmmaker Sir David Attenborough, and primatologist Dame Jane Goodall, among others.

Loglet Lab 5 in development

Loglet Lab 4 is experiencing some difficulties, so users may receive errors on the more complex analysis. We apologize for the inconvenience and are working to alleviate the problems. Meanwhile, with the addition of Albert Strusberg to our team (David Burg, Jason Yung, Perrin Meyer), Loglet Lab 5 is under intensive development and should be available before the end of 2022. Stay tuned.

eDNA work in progress

We post a Schematic of an eDNA metabarcoding protocol for marine fish.

We recently showed that current laboratory protocols optimize sensitivity and reproducibility, especially for more abundant fish populations (ICES J Mar Sci 2022). eDNA metabarcoding is generally considered a qualitative tool for relative abundance. We hope to help develop eDNA metabarcoding as a quantitative tool for absolute abundance (link to pdf work-in-progress).

eDNA Detection of Salamanders

PHE student Samara Davis will present her work with Mark Stoeckle on eDNA detection of threatened salamanders at Northeast Partners in Amphibian and Reptile Conservation Annual Meeting https://northeastparc.org, to be held in West Virginia in August.

eDNA degradation; 2nd National Workshop

PHE’s guest investigator David Thaler offers some stimulating ideas in a memo about ways of understanding and learning from degradation of aquatic eDNA. The title: How long has each particular species’ eDNA been outside the organism from which it came? Some thoughts on the possibility to obtain more information from eDNA analysis of water samples

Meanwhile, Jesse Ausubel and Mark Stoeckle are involved in the program for the 2nd US National Workshop on eDNA, 12-15 September in Southern California. PHE hosted the 1st US national meeting in 2018.
