Tidewater ’11 Recap

After a brief blogcation due to lots of travel around Spring Break (woooo!), I’m back in action.  While I was gone I attended the 25th anniversary meeting of the AFS Tidewater Chapter, which includes the AFS subunits from North Carolina, Virginia, Maryland, and Delaware.  Like…

Striped Bass Eat Too Much

Ah, the majestic striped bass. It’s been called the “perfect fish” by enthusiastic anglers, and represents one of the greatest successes of fisheries management in North America. It fights like a demon when hooked and is delicious when baked. Anglers are so enthusiastic about them…

Resource Partitioning in Sharks – How Predators Get Along

I’ve reached a point in the analysis and writing of my thesis where I can start exploring the ecological concepts behind my results, which inspired me to put up this little post here.  In the marine environment, there is often a high degree of overlap…

Always a Bigger Fish Part 1 – Dogfish as Predators

I’ve found myself with some breathing room between grading my students and studying for my own exams, so it’s time to write up a post I’ve been thinking about for a while.  I’ve been wanting to do a quick summary of the role of the…

Fear Will Keep Them in Line

As a lifelong shark lover whose thesis research happens to be on the subject of predation, I’m a little obsessed with the ecology of predation.  Earlier I posted on trophic cascades and debate over whether they are a strong enough interaction to affect fisheries.  What…

Save the Herring!

Not too long ago the ol’ sister-ship blog posted about the growing Save the Krill movement, which aims to turn at least some conservation resources towards a species that occupies a more basal position in the marine food web.  This makes a lot of sense. …

Feeding Habits Analysis: Clash of the Titans

It’s been a little while since I’ve added to my world-famous series of posts on spiny dogfish gut contents, but today I found something that proved to be entertaining for the entire lab, and perhaps a little heartbreaking for some.  Those of us in the…

Sharks and Trophic Cascades: Cut and Dry?

A recent post over at Chronicles of Zostera referenced a paper that has become a monster in the world of marine ecology and shark conservation.  That paper: Myers et al. (2007).  It’s actually a relatively unassuming paper kind of tucked into an issue of Science,…

Ocean of Pseudoscience: Flipper is a Fraud!

This little bit of pseudoscience is a perfect example of how popular culture can distort our view of how nature works.  Most people are familiar with Flipper, whether it’s the old TV show from the 60’s, the short-lived 90’s reboot featuring Jessica Alba, or the…

Ocean of Pseudoscience: “Voracious Beyond Belief”

I’ll write my first epic Ocean of Pseudoscience post by touching on a subject near and dear to my small shark-loving heart, and in fact it’s the focus of my thesis research.  Ask any commercial fisherman (and even some scientists) if spiny dogfish are devouring…
