This is the place to find the notes and extended reference list for In the Beat of a Heart.
There is also a link to my list on the online reference manager Connotea, on which I am trying to post new references relevant to the book's themes as they are published.
There's also a link to my LibraryThing site, which contains a list of (most of) the books I used, and some photos showing some of the places I travelled to in the name of research. Finally, there's the links page and a list of corrections below, updated as and when my errors become apparent.

Discussing Bergmann's rule, I say that Arctic foxes are "considerably bigger than the red foxes that live in my London garden". If that's so, I must have unusually small foxes, because the two are actually about the same size (some sources say the Arctic is slightly smaller). This comparison was just a foolish brainstorm on my part, although Arctic foxes are the smallest mammals on Spitzbergen.
