This post was chosen as an Editor's Selection for ResearchBlogging.orgAlmost a year ago, we discussed briefly the Krill Surplus Hypothesis. In this model, the removal of large baleen whales created a competitive release for Minke whales, Balaenoptera bonaerensis, exponentially increasing their food supply and and allowing their population to boom. By removing all other krill eating whale from the Antarctic, Minke whales were allowed to thrive, gorging on an endless supply of krill. The flipside to this hypothesis is that now Minke whales have become competitive excluders of other baleen whales, preventing their re-population post-whaling. Minke whale may be preventing the recovery of other whale species.

Many scientists believe that advocacy  is not our proper role. They claim that scientists should instead focus on gathering data and solving scientific problems, and should leave advocacy to others. According to some, publicly advocating a position runs the risk of discrediting a scientist, discrediting a discovery and possibly even discrediting science itself. While I respect the opinions and concerns of my peers, I strongly disagree with them. At least with respect to my discipline of shark conservation biology, our worthy goals are doomed to failure without scientist-advocates.

Tweeting Armageddon

Ok, it wasn’t really armageddon, but the twitter feed from today’s port incident was priceless.

It began with a few tweets by @SFriedScientist

SFriedScientist – Morehead Port is closed due to nine containers being punctured; inside are highly explosive materials know as PETN.

SFriedScientist – Why in the hell are there nine containers of pentaerythritol tetranitrate sitting in my port?

SFriedScientist – and for that matter how the hell did they get left in a position for nine of them to be punctured?

SFriedScientist – Pentaerythritol tetranitrate (PETN) is one of the most powerful high explosives known, with a relative effectiveness factor of 1.66.

SFriedScientist – The XTX8003 extrudable explosive, used in the W68 and W76 nuclear warheads, is a mixture of 80% PETN and 20% of Sylgard 182
