Primary productivity and climate control mushroom yields in Mediterranean pine forests Olano Mendoza, José Miguel Martínez Rodrigo, Raquel Altelarrea, José Miguel Ágreda, Teresa Fernández Toirán, Luz Marina García Cervigón, Ana I. Rodríguez Puerta, Francisco Agueda Hernández, Beatriz Mushrooms play a provisioning ecosystem service as wild food. The abundance of this resource shows high annual and interannual variability, particularly in Mediterranean ecosystems. Climate conditions have been considered the main factor promoting mushroom production variability, but several evidences suggest that forest composition, age and growth play also a role. Long-term mushroom production datasets are critical to understand the factors behind mushroom productivity. We used 22 and 24 year-long time series of mushroom production in Pinus pinaster and Pinus sylvestris forests in Central Spain to evaluate the effect of climate and forest productivity on mushroom yield. We combined climatic data (precipitation and temperature) and remote sensing data (soil moisture and the Normalized Difference Vegetation Index, NDVI, a surrogate of primary productivity) to model mushroom yields for each forest and for the main edible species of economic interest (Boletus edulis and Lactarius deliciosus). We hypothesized that mushroom yield would be related to (i) forest primary productivity inferred from NDVI affects mushroom yields, that (ii) soil moisture inferred from remote sensors will equal the predictive power precipitation data, and that (iii) combining climatic and remote sensing will improve mushroom yield models. We found that (i) previous year NDVI correlated (r =0.41–0.6) with mushroom yields; (ii) soil moisture from remote sensors rivaled the predictive power of precipitation (r = 0.63–0.72); and (iii) primary production and climate variances were independent, thus the combination of climatic and remote sensing data improved models with mean R2 adj as high as 0.629. On the light of these results, we propose as a working hypothesis that mushroom production might be modelled as a two step process. Previous year primary productivity would favour resource accumulation at tree level, potentially increasing resources for mycelia growth, climatic conditions during the fruiting season control the ability of mycelia to transform available resources into fruiting bodies Junta de Castilla y León [project VA026P17]; and the Spanish Ministry of Science, Innovation and Universities [grant numbers DI-17-09626, PTQ-16-08411 and IJCI- 2017-34052 to RMR, BÁ, and AIGC, respectively]. 2025-01-15T08:05:24Z 2025-01-15T08:05:24Z 2020 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Agricultural and Forest Meteorology 288-289: 108015. https://uvadoc.uva.es/handle/10324/73839 10.1016/j.agrformet.2020.108015 1 7 spa info:eu-repo/semantics/openAccess Elsevier application/pdf https://uvadoc.uva.es/bitstream/10324/73839/3/Primary-productivity-and-climate-control-mushroom-_2020_Agricultural-and-For.pdf.jpg Hispana TEXT http://rightsstatements.org/vocab/CNE/1.0/ UVaDOC.
