Mycorrhizal Fungi: Invisible Architects of Ecosystem Diversity by Jeremiah A. Henning

Presented by Jeremiah A. Henning, post-doctoral research associate in the department Ecology, Evolution, and Behavior at the University of Minnesota, at the Bryant Lake Bowl on November 11th, 2017.
Although they are an invisible group of soil-dwelling organisms, mycorrhizal fungi are critical to the maintenance of plant diversity, plant productivity, and the storage of carbon in soils. Mycorrhizal fungi likely hold the key to how ecosystems will respond to global change. For my talk, I will introduce the audience to the group of fungi I study, Glomeromycota, then briefly introduce a couple of the classic studies demonstrating the important links between fungal diversity, plant diversity, productivity, and soil carbon. Once I lay this groundwork, I will transition into how these fungi may shape ecosystem response to global change, talking very generally about the carbon cycle and a few of my past and current research projects.
I am currently a post-doctoral research associate in the department Ecology, Evolution, and Behavior at the University of Minnesota. I recently relocated back to the Midwest after completing my Ph.D. at the University of Tennessee. Overall, my research focuses on understanding patterns that maintain global biodiversity and how contemporary global change is reshaping biodiversity. Although my research has taken me from tropical rainforests to mountain tops, and up to the arctic tundra permafrost, the tall grass prairie always holds a place in my heart, and I will focus most of my talk on work that has been conducted in a Tallgrass prairie near Eau Claire, WI.

    I'd love to know what you think about the book Teaming with Fungi by J. Lowenfels. Wondering specifically what you think about his supposition that while woodland/orchard areas are naturally finally dominated soils, vegetable/grain production areas are bacterially dominated soils and benefit less from fungal/mycelial infiltration/integration?

    Hello, newly subbed. I have just learned about mycorrhizal fungi and I’m very excited and fascinated. I collect rainwater and use the commercial mosquito dunks in my rain barrel to prevent mosquitoes. I’m wondering if the bacillus in the mosquito dunks is hospitable to the fungus? Any advice you can share is greatly appreciated

    I am too late to this. But what do you suggest for soil borne fungal infections on plant ? Like, root rot, stem rot etc ? Right now, the only way to get rid off the infection is to use fungicide through drip irrigation.

    I had assumed that mycorrhizal fungi were basically growing through all soil anyway, just at incredibly low levels, or that spores remained where the fungi had existed once, and all that would be needed was to provide the conditions needed for the fungi to flourish (or the spores to grow) instead of needing to manually introduce spores or fungi. I realise assumption is dangerous... can anyone provide any links to research on that? Ie if we provide an environment (plants etc) that support and work with mycorrhizal fungi, will the fungi basically always just show up or do we actually need to introduce the fungi? Edited: I just did a little searching, it appears that the spores only live about 18 months and the actual fragments only a few months (once separated from roots). So under some circumstances it does seem that soil could actually, literally not contain any of these fungi in either form.

    In what form is the carbon in? What do you mean when you say carbon? Carbon is a single element and clarification of this would be great

    Exudates. Simple sugars hence "The Liquid Carbon Pathway" Christine Jones ... But think of it as more of a trade of Carbon for Nitrogen, Phosphate, and Potassium (among all the others). Also they "Quorum Sense" using an entirely newly discovered plethora of signalling exudates and receptor systems. Finally remember the soil bacteria adhere to minerals and invade the plants provided they escape the bacteriophage viruses. It's a right circus!

    He specifically said that the fungi are connected via many plants, so most likely when the plant was killed either they went dormant or died also. But it didnt lose any of the beneficial properties as their attached to other plants and when new plants are established, im pretty sure the hyphae will regain their hold on those new plants too. Kind of like if your arm is infected with a virus and you cut it off, everything connected to your arm inside and out is lost but your body still functions without it and you can live on. Fungi is the same.

    36:15: not much manure is used in agriculture; mostly artificial nitrogen (hugely polluting in its production) is applied. If you say 'manure', then you ought to point at livestock droppings form meat- and dairy cattle (not to mention methane et al). Just reduce your meat consumption to a tiny amount to remedy that one. Simple. Grow your own veg/fruit according to regenerative principles, and the world will be a better place on mány levels. Something to work toward, right?

    @@StanOwden it certainly qualifies him as a scientist far more than suggesting that 5 minutes of searching is sufficient does. The 5 minute comment implies a lack of training and experience in science. A core skill/ability that a scientist needs, is to know what they know, versus what they do not know. He does not know GMOs. Given that he was giving a presentation based on scientific research, for him to comment on GMOs when he has no actual knowledge of GMOs would have been... questionable.
