Microbiomes change the rules of host evolution

Natalia L. Komarova, Margaret Y. Demmel, Jonathan B. Shurin, Dominik Wodarz

This study shows microbiomes alter host evolutionary dynamics by changing effective population size and selection coefficients, leading to different evolutionary outcomes than classical predictions.

Does host diversity beget microbiome diversity? Effects of zooplankton diversity and composition on environmental and host-associated microbes

Joshua H. Dominguez, Christopher B. Wall, Margaret Y. Demmel, Jonathan B. Shurin

The paper investigates how zooplankton diversity and composition affect host-associated and environmental microbiomes, finding contrasting effects on microbiome diversity depending on host species.
