Changes in the microbial community structure of bacteria, archaea and fungi in response to elevated CO 2 and warming in an Australian native grassland soil
Helen L. Hayden,Pauline M. Mele,Damian S. Bougoure,Claire Y. Allan,Sorn Norng,Yvette M. Piceno,Eoin L. Brodie,Todd Z. DeSantis,Gary L. Andersen,Amity L. Williams,Mark J. Hovenden +10 more
TL;DR: Bacteria, archaea and fungi in soil responded differently to elevated [CO2], warming and their interaction, and the approach of focusing on specific taxonomic groups provides greater potential for understanding complex microbial community changes in ecosystems under climate change.

Warming prevents the elevated CO2‐induced reduction in available soil nitrogen in a temperate, perennial grassland
Mark J. Hovenden,Paul C. D. Newton,R. A. Carran,P. W. Theobald,Karen Wills,J. K. Vander Schoor,Amity L. Williams,Yui Osanai +7 more
TL;DR: In this article, the authors used ion exchange membranes to assess the availability of dissolved organic N, ammonium and nitrate in an Australian, temperate, perennial grassland and found that CO2 enrichment in such a grassland did reduce soil nitrogen availability, mostly by reducing nitrate availability.

Flowering phenology in a species-rich temperate grassland is sensitive to warming but not elevated CO2.
Mark J. Hovenden,Karen Wills,Jacqueline K. Vander Schoor,Amity L. Williams,Paul C. D. Newton +4 more
TL;DR: Flowering phenology appears insensitive to increasing [CO2] in this ecosystem, although the response to warming varies between years but can be strong.
Warming and elevated CO2 affect the relationship between seed mass, germinability and seedling growth in Austrodanthonia caespitosa, a dominant Australian grass
Mark J. Hovenden,Karen Wills,Rebecca E. Chaplin,Jacqueline K. Vander Schoor,Amity L. Williams,Yui Osanai,Paul C. D. Newton +6 more
TL;DR: Given that both elevated CO2 and warming reduced seed mass, quality, germinability or seedling growth, it is likely that global change will reduce population growth or distribution of this dominant species.

Soil carbon storage under simulated climate change is mediated by plant functional type
TL;DR: This article investigated the role of plant functional type (FT) on biomass and SOM responses to the long-term treatments by carefully sampling soil under patches of C3- and C4-dominated vegetation.
