As it turns out, you can&#8217;t go climb a mountain to get away from it all,&#8221; said UCR microbial ecologist Mia Maltz, who led the study.<\/p>\n<p>The researchers detail the types of fungi and bacteria landing from low to high elevations in the mountains in a new <i>Frontiers in Microbiology<\/i> paper. &#8220;Some of these microbes can cause crop failures and human respiratory disease,&#8221; said Maltz. <\/p>\n<p>At the lower elevations, the researchers found more powdery mildews and sooty molds, which can lead to forest blight and crop losses. They also found fungi like Cryptococcus, a sticky yeast, and the plant pathogen Alternaria, both of which can be inhaled or form infections in human lungs. <\/p>\n<p>The researchers were not surprised to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/ncomms14800\">learn<\/a> that dust in the Sierra Nevada was a mixture of soil particles from as far away as China&#8217;s Gobi Desert and as near as California&#8217;s San Joaquin Valley. They were surprised, however, to learn about the mix of microbes in the dust, and where they landed in the mountains. <\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/drought-increases-micr-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/drought-increases-micr-1.jpg\" data-sub-html=\"Microbes discovered in Sierra Nevada dust.

Instead, they found that when the dust was more mixed, it had lower species richness. <\/p>\n<p>Dust samples were collected at four Critical Zone Observatory network <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/criticalzone.org\/\">sites<\/a> in the Sierras, at elevations ranging from 400 to 2,700 meters. The researchers suspect microbes steadily fell out of the dust as they <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">travel<\/a>ed, which may be why fewer types of bacteria and fungi were found at the top than at the base of the mountains.<\/p>\n<p>&#8220;I like to think of diversity as being a good thing, like a safety net. You could lose a few and still sustain the essential functions of the community,&#8221; Maltz said. &#8220;In this case, loss of microbial diversity at the higher elevations doesn&#8217;t seem to be a negative; we&#8217;re losing pathogens instead.&#8221;<\/p>\n<p>Some dust traveling the globe and landing in the Sierra Nevada is natural, and even beneficial for mountain ecosystems. Dust carries fungi and bacteria that help decompose organic debris and enrich the soil.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/drought-increases-micr-2.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/drought-increases-micr-2.jpg\" data-sub-html=\"UC Riverside scientists extracting microbes from Sierra Nevada dust samples.

Pine trees, in this ecosystem, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.aao1588\">derive<\/a> more than 80% of what they need to produce their needles from dust. <\/p>\n<p>&#8220;Without dust, trees wouldn&#8217;t have what they need to flourish and fix carbon from the atmosphere at the level they&#8217;re currently doing it,&#8221; said UCR environmental microbiologist and study co-author Emma Aronson.<\/p>\n<p>However, in a future climate, there are likely to be more droughts, resulting in more dust. If a greater proportion of the microbes landing in the Sierra Nevada are pathogenic, that could affect which species of plants and animals are able to persist. <\/p>\n<p>&#8220;With increased die-off of large conifers and other plants, there would be less carbon sequestered than there has been historically, and the atmosphere could get even hotter,&#8221; Aronson said. <\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/drought-increases-micr-3.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/2022\/drought-increases-micr-3.jpg\" data-sub-html=\"UCR scientists erecting fences to keep cattle from damaging dust collection instruments.
