AbstractMutualisms evolve over time when individuals belonging to different species derive fitness benefits through the exchange of resources and services. Although prevalent in natural and managed ecosystems, mutualisms can be destabilized by environmental fluctuations that alter the costs and benefits of maintaining the symbiosis. In the rhizobia-legume mutualism, bacteria provide reduced nitrogen to the host plant in exchange for photosynthates that support bacterial metabolism.

AbstractThe diversity of intrinsic traits of different organic matter molecules makes it challenging to predict how they, and therefore the global carbon cycle, will respond to climate change. Here we develop an indicator of compositional-level environmental response for dissolved organic matter to quantify the aggregated response of individual molecules that positively and negatively associate with warming.

4 DISCUSSION In this study, we modeled how macroevolutionary rates influence present-day microbial species diversity in an attempt to further constrain the estimates and predictions from previous studies ranging from 106 to 1012 species (Larsen et al., 2017; Locey & Lennon, 2016; Louca et al., 2019; Wiens, 2021) to see whether some of these estimates are macroevolutionarily infeasible.
