Are sandbar sharks more like bowhead whales or cod?

At first glance, the question posed in the title seems silly. Both cod and sandbar sharks are fish, therefore they must be more similar to each other than either are to bowhead whales (which are mammals). However, a recent conservation genetics paper has demonstrated that one aspect of a sandbar shark’s life history is  more similar to that of bowhead whales: both sandbar sharks and bowhead whales have an effective size that is very similar to their census size.

Crowdsourcing ConGen – A Reading List

Conservation, Science

This is a little different from my usual Crowdsourcing ConGen posts. I recently completed my qualifying exams for PhD candidacy, so have a very large reading list compiled for population and conservation genetics. So, if you’re interested in the field, you should check out some of these papers, and if you know of any others that should be included, please let me know in the comments.

Crowdsourcing ConGen – Populations in Hardy-Weinberg Equilibrium

This post is part of the Crowdsourcing ConGen project. Crowdsourcing is the process of opening up a resource to a community for input and contributions. Throughout the coming year I’ll be posting manageable pieces of this document for the audience of Southern Fried Science to read and review. Please visit the main post for an overview.

“I have never done anything useful. No discovery of mine has made, or is likely to make, directly or indirectly, for good or ill, the least difference to the amenity of the world.” ~ Godfrey Harold Hardy

The simplest model for a population is one in which the frequencies of alleles and genotypes remains constant from generation to generation. Under this model, there are no outside forces influencing selection, there is no tendency for any allele or genotype to be favored over any other, diploid alleles will recombine randomly in accordance with Mendelian inheritance. A population that behaves this way is said to be in Hardy-Weinberg Equilibrium. This almost never happens.
