Charlie learns how to build a Latitude Hook

I write a lot about shark conservation issues, but I rarely focus on their fellow elasmobranchs. Rays and skates have similar life history strategies as sharks, and many species are similarly overfished. A friend just sent me a cool paper about the conservation of skates, which provides an excellent opportunity to remedy this oversight.
A major issue standing between well-managed elasmobranch fisheries and the mess we find ourselves in today is species identification. Many species look very similar (in some cases, DNA tests are required to tell them apart), which makes recording catch statistics extremely difficult. In fact, United States fishery management policy sometimes focuses on species complexes (i.e. “Large Coastal Sharks”) of sharks rather than individual species. Species identification is a major issue for skates as well.

The framework is set up early in life and historically, scientific knowledge was held within a religious ‘way of … Read More “Vignette from the Anthropology of Knowledge: Cree Hunting” »

This announcement was timed to coincide with a high-level United Nations meeting to review millennium development and global biodiversity conservation goals.
The two Presidents had this to say:

Political junkies like myself know that Republicans are expected to regain the House of Representatives following elections this November. The Democrats’ odds of keeping the Senate improved with the primary victory of corrupt Christine O’Donnell last week, but there is still a chance that the Republicans will retake the Senate. This isn’t surprising- the opposition … Read More “Save the light bulb, not the planet: A sneak peak at how Republicans will run the House” »
