Revisiting the ‘Gadgil effect’: do interguild fungal interactions control carbon cycling in forest soils?

Fernandez, Christopher W., Kennedy, Peter G.·2016·New Phytologist

Abstract

Summary: In forest ecosystems, ectomycorrhizal and saprotrophic fungi play a central role in the breakdown of soil organic matter (SOM). Competition between these two fungal guilds has long been hypothesized to lead to suppression of decomposition rates, a phenomenon known as the ‘Gadgil effect’. In this review, we examine the documentation, generality, and potential mechanisms involved in the ‘Gadgil effect’. We find that the influence of ectomycorrhizal fungi on litter and SOM decomposition is much more variable than previously recognized. To explain the inconsistency in size and direction of the ‘Gadgil effect’, we argue that a better understanding of underlying mechanisms is required. We discuss the strengths and weaknesses of each of the primary mechanisms proposed to date and how using different experimental methods (trenching, girdling, microcosms), as well as considering different temporal and spatial scales, could influence the conclusions drawn about this phenomenon. Finally, we suggest that combining new research tools such as high‐throughput sequencing with experiments utilizing natural environmental gradients will significantly deepen our understanding of the ‘Gadgil effect’ and its consequences on forest soil carbon and nutrient cycling.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
