Two papers out this week on the population dynamics and epidemiology of the chytrid pathogen of amphibians, Batrachochytrium dendrobatidis (Bd). This is work from the Vredenburg and Briggs labs that includes several decade-long studies of frog declines and the prevalence of Bd. See Vance in action swabbing a frog In the Briggs et al paper, they describe [...] A year ago researchers at James Madison University discovered that, Pedobacter cryoconitis, a bacteria first found on the skin of red backed salamanders, was found to prevent the growth of the chytrid B. dendrobatidis, which is currently decimating frog populations.
Another asexual species of fungi also has evidence for the meiosis-specific process of Repeat Induced Point-mutations (RIP). [...] Nature news articles on the frog decline (doi:10.1038/452394a) and Batrachochytrium dendrobatidis (doi: 10.1038/452394a) [...] I’m including a recapping as many of the talks as I remember. There were 6 concurrent sessions each afternoon so you have to miss a lot of talks. The conference was bursting at the seams as it was- at least 140 people had to be turned away beyond the 750 who attended.
