Their growth, determined by their carbon balance, can be affected by various climatic drivers. The effects of individual drivers are clear from laboratory experiments, but the relative importance of different drivers along climatic gradients and their underlying mechanisms are largely unknown. Moreover, the effects of seasonal acclimation on the annual carbon balance are not fully understood either. Therefore, we aim at determining the level and variation of annual biocrust carbon balances and their connection to climatic drivers along environmental gradients. In addition, we explore the role that acclimation plays in the carbon balance of biocrusts}, language = {en} } @misc{PoradaBaderBerdugoetal., author = {Porada, Philipp and Bader, Maaike Y. and Berdugo, Monica B. and Colesie, Claudia and Ellis, Christopher J. and Giordani, Paolo and Herzschuh, Ulrike and Ma, Yunyao and Launiainen, Samuli and Nascimbene, Juri and Petersen, Imke and Raggio Qu{\´i}lez, Jos{\´e} and Rodr{\´i}guez-Caballero, Emilio and Rousk, Kathrin and Sancho, Leopoldo G. and Scheidegger, Christoph and Seitz, Steffen and Van Stan, John T. and Veste, Maik and Weber, Bettina and Weston, David J.}, title = {A research agenda for non-vascular photoautotrophs under climate change}, series = {New Phytologist}, volume = {237 (2023)}, journal = {New Phytologist}, number = {5}, issn = {0028-646X}, doi = {10.1111/nph.18631}, pages = {1495 -- 1504}, abstract = {Non-vascular photoautotrophs (NVP), including bryophytes, lichens, terrestrial algae, and cyanobacteria, are increasingly recognized as being essential to ecosystem functioning in many regions of the world. Current research suggests that climate change may pose a substantial threat to NVP, but it is highly uncertain to what extent this will affect the associated ecosystem functions and services. Here, we propose a research agenda to address this urgent question, focusing on physiological and ecological processes that link NVP to ecosystem functions while also taking into account the substantial taxonomic diversity across multiple ecosystem types. Accordingly, we developed a new categorization scheme, based on microclimatic gradients, which simplifies the high physiological and morphological diversity of NVP and worldwide distribution with respect to several broad habitat types. We found that habitat-specific ecosystem functions of NVP will likely be substantially affected by climate change, and more quantitative process understanding is required on (1) potential for acclimation (2) response to elevated CO2 (3) role of the microbiome and (4) feedback to (micro)climate. We suggest an integrative approach of innovative, multi-method laboratory and field experiments and eco-physiological modelling, for which sustained scientific collaboration on NVP research will be essential.}, language = {en} }
