Current Biology “Positively Frequency-Dependent Interference Competition Maintains Diversity and Pervades a Natural Population of Cooperative Microbes” This is another great example of how theory that does not consider space is a poor representation of nature. Here, the diversity of a soil bacterium (Myxococcus xanthus) is shown to be potentially explained by positive frequency-dependent selection, the Read More
