     Summary:   
         Using a long-term multifactor experimental field site researchers   
         showed that experimental warming of a tallgrass prairie ecosystem   
         significantly altered the community structure of soil archaea and   
         reduced their taxonomic and phylogenetic diversity.

   FULL STORY   
   ==========================================================================   
   Led by Jizhong Zhou, Ph.D., the director of the Institute for   
   Environmental Genomics at the University of Oklahoma, an international   
   research team conducted a long term experiment that found that climate   
   warming reduced the diversity of and significantly altered the community   
   structure of soil archaea.   
      
   Their findings are published in the journal Nature Climate Change.   
      
   At the microbiological level, life can be described as belonging to   
   one of three kingdoms -- how species are described in relation to one   
   another. Eukarya contains complex organisms like animals and plants and   
   microorganisms such as fungi. The other two categories, bacteria and   
   archaea, are comprised only of microorganisms. Archaea are prevalent in   
   a range of environments, from some of the most hostile like volcanoes   
   and permafrost. However, archaea are also common in the human microbiome   
   and as an important part of soil ecology.   
      
   "As temperature is a major driver of biological processes, climate   
   warming will impact various ecological communities," Zhou said. "Based   
   on long-term time- series data, our previous studies revealed that   
   experimental warming leads to the divergent succession of soil bacterial   
   and fungal communities, accelerates microbial temporal scaling, reduces   
   the biodiversity of soil bacteria, fungi and protists, but increases   
   bacterial network complexity and stability.   
      
   However, how climate warming affects the temporal succession of the   
   archaeal community remains elusive. Archaea are ubiquitously present   
   in soil and are vital to soil functions, e.g., nitrification and   
   methanogenesis."  Using a long-term multifactor experimental field   
   site at OU's Kessler Atmospheric and Ecological Field Station, the   
   researchers showed that experimental warming of a tallgrass prairie   
   ecosystem significantly altered the community structure of soil archaea   
   and reduced their taxonomic and phylogenetic diversity. In contrast   
   to the researchers' previous observations in bacteria and fungi, their   
   finds show that climate warming leads to convergent succession of the   
   soil archaeal community, suggesting archaeal community structures would   
   become more predictable in a warmer world.
