It's been about 2 years since my last blogroll update. I've rearranged some of the headings and made a few other changes. Notably:
Deletions: Diamictite and The Happy Scientist have been post-free for more than a year, and sporadic before then. I'll keep an eye out, and if posts reappear, I'll add them back in.
The field experiences of ecologists and geologists are pretty damn close, and I've found myself using Dynamic Ecology many times for post inspiration.
I'm also adding a paleontology blog to round out the geology list - check out Fossils and Other Living Things.
Feel free to poke through the blogs!
