Evolution of resource use along a gradient of stress leads to increased facilitation

Abstract: The stress‐gradient hypothesis (SGH) posits that the relative importance of facilitative interactions versus negative interactions increases as levels of abiotic stress increase. Originally formulated in empirical studies of plant populations, in recent years the SGH has been found to describe how interactions change in response to stress in a wide range of species including algae, mussels and moths. However, there has been little theory attempting to predict patterns from first principles in relation to diffe… Show more

“…The SGH predicts that positive interactions should be more prevalent in stressful environments, while more favourable environments should favour competition. This hypothesis has been supported and tested mainly in plant systems (Callaway et al, 2002;Eränen and Kozlov, 2008;Pugnaire and Luque, 2001), and more recently in microbial communities (Fetzer et al, 2015;Hoek et al, 2016;Lawrence and Barraclough, 2016;McCluney et al, 2012;Piccardi et al, 2019).…”

“…As the residual correlations estimated by JSDMs simply indicate whether co‐occurrence is lower or higher than expected by chance given the environment, we can assume that current JSDM implementations will not allow unambiguous distinction of predator–prey (or consumer–resource) relationships and competitive or facilitative interactions, and will need further model development in this respect. Another challenge is that interspecific interactions are not constant in space and time (Callaway et al , Meier et al , He et al , Lawrence and Barraclough ), and it has thus been proposed that non‐stationarity in interaction coefficients should be considered in future research (Kissling et al , Wisz et al , Warton et al ) but hitherto only one worked example using multi‐species occupancy modelling exists (Rota et al ).…”

“…competitive exclusion is facilitated by evolutionary change in between-species interactions [13,[26][27][28], resulting in, crossfeeding [26] or a niche shift to underexploited resources [29 -31]. In most bacterial experiments, monoclonal isolates are assembled [13,21,23,26,32] and any evolutionary change is based on de novo mutations [33 -35], potentially imposing constraints on evolution [4].…”
