Over 15 years of ocean science and conservation online
Just when you thought it was safe to read another decade-in-review listicle…
As the 2010’s come to an end, it’s a time to reflect on the often-problematic decade that was as we plan for a hopeful future. I am a sucker for year-in-review and decade-in-review listicles, and was devastated to learn that no one had yet written a decade-in-review listicle for sharks! Please enjoy my official, scientific list of the most important science, conservation, and pop culture sharks from the past decade.
It’s easy to get discouraged or demoralized as an environmentalist in today’s world. It seems like every day brings more devastating news. Half of the world’s wildlife has died in my parents’ lifetime, and current rates of extinction may be up to 10,000 times higher than the natural background rate. We’re losing a terrifying number of birds and insects, and a million species are considered threatened or endangered. Things are bad enough that “eco anxiety” is now a recognized mental health condition.
It is said that in the environmental movement, all of our victories are temporary, and all of our defeats are permanent. Much of the current focus of environmental advocacy has been described as “playing against the slaughter rule,” hoping not to win but to avoid getting totally wiped out in our inevitable loss.
In the face of all this, I’m often asked how I can remain so optimistic, and so motivated to keep working. Some people are surprised to learn that a large part of my answer comes from my Jewish faith.

My 35th birthday is next week, and I am calling upon the forces of the Internetz to help make it an amusing one. As you all know, sandbar shark is #BestShark. This spectacular shark is even the logo of my new consultancy! I want you to help me celebrate my birthday by creating sandbar shark … Read More “Announcing the #BestShark contest for David’s birthday: make sandbar shark memes and art, win prizes!” »

I can’t imagine a more useful introductory reference guide for new or prospective graduate students starting their career in marine biology than “Shark Research: Emerging Technologies and Applications for the Field And Laboratory”. This book is designed for people who have little to no familiarity with a research discipline but are about to start working in that discipline, a large and important audience that is often ignored by books and review papers geared towards people who are already experts. So many graduate students are told to learn a new research method by reading technical literature that assumes they already know this stuff, resulting in stress and frustration.
My Postdoctoral research has focused on understanding the causes and consequences of public misunderstanding about shark fisheries management. While scientists overwhelmingly support sustainable fisheries management as a solution to shark overfishing, many concerned citizens and conservation activists prefer total bans on all shark fishing and trade. Some go so far as to (wrongly) claim that sustainable shark fisheries cannot exist even in theory and do not exist in practice anywhere in the world, and that bans are the only possible solution.
There’s an important piece of data that very rarely makes it into these discussions. Amidst the ongoing discussions about whether or not sustainable shark fisheries are even possible, one right in my backyard became the first shark fishery anywhere in the world to be certified as sustainable by the Marine Stewardship Council.
However, a few years after BC’s spiny dogfish fishery got certified, the certification was quietly withdrawn. I couldn’t find any information in the MSC reports, or in associated scientific literature or government reports, that explained what happened to this fishery, which was thriving until recently. No scientists, managers, or conservation advocates who I asked about this knew exactly what happened to BC’s spiny dogfish fishery.
We have a new paper out today in the journal Aquatic Ecology! Read it here, open access copy here. This is the last paper from my Ph.D. dissertation, and coauthors include my Ph.D. advisor Dr. Neil Hammerschlag, Ph.D. committee member Dr. Mike Heithaus, and colleague Dr. Les Kaufman. It’s called “Intraspecific Differences in Relative Isotopic Niche Area and Overlap of Co-occurring Sharks,” which I think rolls right off the tongue and would make a pretty sweet band name. This research was crowdfunded by the SciFund challenge a few years ago, so thanks again for your support! I want to tell you a little bit about what we did and what we found!

After months of expert and public consultation, the Florida Fish and Wildlife Conservation Commission has announced the draft text of new regulations that will govern land-based shark fishing. It’s mostly very good news that directly addresses most of our concerns!
A review of the problem
Land-based anglers in Florida (those who fish from beaches, docks, and piers) catch large numbers of threatened, protected species, handling them in needlessly cruel ways that likely result in mortality or permanent injury. Anglers are aware that what they’re doing causes harm to certain species and violates some existing regulations. Hammerhead sharks in particular are extremely physiologically vulnerable and need to be released much faster than they are currently being released or else they will very likely die.
(Learn more: see my paper on this subject, my blog post summarizing that paper, an open letter calling for action, an op-ed I wrote about this, a review of the existing rules and how they’re regularly violated, and a years-old blog post describing one problematic incident with land-based shark fishing)
