Spurred by PHE Guest Investigator and microbiologist David Thaler’s publication, “Is global microbial biodiversity increasing, decreasing, or staying the same?” , David and Jesse Ausubel co-author a 900-word essay raising the question of what’s happening to microbes in RealClear Science.
Area of Research: DNA Barcoding
As plant and animal diversity wanes, is microbial life changing too?
PHE Guest Investigator and microbiologist David Thaler has published the paper, “Is global microbial biodiversity increasing, decreasing, or staying the same?” in Frontiers in Ecology and Evolution. The answer is, we do not know.
The paper arose from Zoom discussions PHE began holding every Tuesday and Thursday noon during COVID lockdown of our NYC group members with colleagues in California, Israel, Switzerland, and elsewhere. Bravo to David for asking a bold question and putting it onto the research agenda. Thanks to Gary Borisy (Forsyth Institute) and Jessica Mark Welch (Marine Biological Laboratory) for sharing images. A Press Release from the journal summarize the paper.

1-hour video about Ocean Decade
24 March 2021 Jesse Ausubel formed part of a lively 70-minute panel discussion on Oceans with:
Ms. Maya Gabeira, Big Wave Surfer, 2X World Record Holder, Oceana Ambassador
Mr. Romain Troublé, Director-General, Tara Foundation
Mr. David Eades, Chief Presenter, BBC TV News, Moderator 1
Ms. Taylor Goelz, Program Manager, Shipping Decarbonization Initiative, Aspen Institute | Member, Ocean Decade Early Career Ocean Professional Informal Working Group, Moderator 2
The full 4’42” video of the UNESCO Forum on Biodiversity: On the road to Kunming is here on YouTube.
The Ocean session starts at 1:57 and lasts to 3:09. Jesse’s opening remarks (about better measurement of abundance of ocean life) start at 2:07 (3 minutes) and his pitch for soundscapes is at 2:41:35 (1.5 minutes). The entire session is good listening (and some video too).
Let’s measure the abundance of marine life
The lively website Real Clear Science publishes Jesse Ausubel’s short essay Time to Measure the Abundance of Ocean Life prepared for the 24 March 2021 UNESCO FORUM: Our Planet, Our future
Maritime Executive also shares the piece as an Op-Ed: Time to Measure the Abundance of Ocean Life.
eDNA in Maritime Executive
The excellent magazine and website Maritime Executive runs an editorial by Jesse Ausubel and Alan Curry How eDNA Could be a Cornerstone of the New Blue Economy The essay draws on their chapter in the forthcoming book: Preparing a Workforce for the New Blue Economy: People, Products and Policies, Liesl Hotaling and Richard W. Spinrad (eds).
Great Global Fish Count
We post the concept paper for the Great Global Fish Count and the 5 slides Jesse Ausubel and Mark Stoeckle prepared for the Ocean Studies Board virtual meeting to discuss “ocean shots” for the new Ocean Decade. The video of Jesse’s 10-minute talk starts at 24’10” of the Feb 3 Ocean Decade Plenary 2 session of video showcase of the Ocean Decade: U.S. Launch Meeting February 3-4, 2021.
The USA Ocean Decade Ocean-Shots site is here.
Here is the list of 87 Ocean-Shot ideas.
The journal of the Marine Technology Society will publish a special issue with short articles on many of the ideas. This is our 2-page version of the GGFC.
10th Anniversary of Census of Marine Life
Marking the 10th anniversary of the completion of the first Census of Marine Life, the Consortium for Ocean Leadership organized a virtual symposium 26 January 2021: Observing Life in a Changing Ocean Exploring a Census of Marine Life Today. Jesse Ausubel gave the opening talk, a 25-minute retrospective on the CoML. We post a pdf of the slides here.
We highly recommend re-visiting the concluding report of the CoML, Highlights of a Decade of Discovery, and much other material still available at www.coml.org
eDNA of Red Gate Farm waters, Martha’s Vineyard
At the end of August 2020, Jesse Ausubel sampled 7 locations in parts of what will become the new Squibnocket Pond Reservation (Red Gate Farm) in Aquinnah on Martha’s Vineyard for the Sheriff’s Meadow Foundation (SMF), which will manage the property together with the MV Land Bank. The late fall 2020 SMF newsletter runs a good article by Kate Feiffer about the findings, analyzed by Mark Stoeckle, which include a lot of eel and muskrat DNA and a little bit of black-crowned night heron.
