- A very fine essay on the holobiont concept for non-microbiologists.
- A general introductory overview of the holobiont concept.
- The holobiont concept and the coral symbiosis.
- A partial history of the development of the holobiont concept.
- Dr. Casadevall suggests that context and thus outcomes describes the term "pathogen," and a similar analysis applies to the holobiont.
- A very short description of the holobiont concept.
- Another overview of the holobiont concept in general, coauthored by Dr. Kohl.
- Some basic rules for thinking about the holobiont concept.
- A video introduction to the holobiont concept, by Dr. Seth Bordenstein.
- I highly recommend this essay by the science writer Carl Zimmer, "The Human Lake," to think of the connections between lake ecology and microbial interactions with humans.
- Another wonderful article recommended by Dr. Kohl, by Dr. Margaret McFall-Ngai and coauthors, detailing the impact microbes have on animals over evolution and development.
- The wood rat – creosote – microbiome connection to the holobiont concept, discussed on this podcast (coauthored by Dr. Kohl).
- The fascinating work by Dr. Kohl and colleagues showing the relationship between tadpole development and pond microbes discussed in this podcast.
- A must read article by Dr. Kohl and colleagues, "Through the microbial looking glass: our shifting understanding of the holobiont and microbes as mediators of organismal biology," illustrates the development and influence of the holobiont concept.
- Dr. Richard Prum's book, "Performance All the Way Down," was discussed during this podcast. There is also a video where Dr. Prum discusses the ideas in this book, describing gene regulation as a performance.
