15 important shark conservation and management terms explained with memes

Posted on April 1, 2013 by David Shiffman

If interested citizens want to get involved in conservation and management policy, it’s absolutely vital to use proper terminology. The policy world can be full of confusing jargon, but there are few ways to discredit yourself in the eyes of decision makers as quickly as using a critical term incorrectly. In fact, it isn’t uncommon for a decision maker’s response to a petition or public comment to consist entirely of correcting inaccurate terminology, if a response is issued at all. There are well over 100 acronyms and terms that I’ve seen regularly used, but in the interest of brevity, I’ve selected what I believe to be the 15 most important terms that I’ve seen people repeatedly use incorrectly.

For each term, I’ve provided a definition from a scientific paper or technical report whenever possible. I have also provided some additional explanation in my own words, and some assistance from familiar memes. Whenever possible, I’ve linked to blog posts, articles, or websites that provide even more information. Most of these terms are broadly applicable to fisheries management policy, but some are specific to shark fisheries. It is not my intention with this post to strongly advocate for or against any specific policy (I do plenty of that with other posts), but to make sure everyone is speaking the same language.

Misunderstood Marine Life # 3 – Cryptics and Cryptids

Posted on October 6, 2011 by Andrew David Thaler

In my mind, where I imagine people are so interested in what I do that they hang on every carefully chosen word I write, I imagine some unspecified mob of readers looking over my I *heart* cryptozoology post and going “Whoa now, pardner!” (yes, you all sound like cowboys in my mind) “You just said there was a difference between cryptozoology and real zoology, but you deal with cryptic species all the time! What’s up with that?”

Conservation and the Concept of Species in a Biodiversity Crisis (Part 1)

Posted on January 24, 2011 by Andrew David Thaler

In The Mass Extinction of Scientists Who Study Species, Dr. Craig McClain argues that we are loosing a fundamental unit of biological science – the Taxonomist. He’s right, of course. Taxonomy is a shrinking field. Entire phyla sit, unstudied, as the expertise necessary to understand them retires and expires. With few to train the next generation of taxonomists, the field could slowly vanish. Molecular tools are supplanting traditional taxonomy (once described to me as “the ability to identify hundreds of species of centimeter-long worms by counting ass-hairs under a microscope”) as the de rigueur method for identifying organisms.

I do not disagree with Craig. Losing skilled taxonomists is tragic for the biological sciences. Unlike many leading the charge in support of taxonomy, I did not benefit from a rigorous taxonomic study in my early career. I fall into the same camp as Dr. Holly Bik, relying primarily on molecules, not morphology, to draw the distinctions between my samples. I never identified species by counting the ass-hairs on a worm, and my education is poorer for it.
