Facilitation in plant communities: the past, the present, and the future (2007, background): “Michalet et al. (2006) further developed these ideas, suggesting that facilitation promotes diversity at medium to high environmental severity by expanding the range of stress-intolerant competitive species into harsh physical conditions (as discussed by Bruno et al. 2003 and demonstrated by Choler…”
Facilitation in communities: underlying mechanisms, community and ecosystem implications (2016, methodology): “This controversy was followed by the publication of other alternative models to the SGH, proposing a collapse of facilitation in extremely stressful conditions (Michalet et al. 2006, 2014a; Xiao et al. 2009; Holmgren & Scheffer 2010; Verwijmeren et al. 2013; Le Bagousse-Pinguet et al. 2014a).”
Weak and variable relationships between environmental severity and small‐scale co‐occurrence in alpine plant communities (2007, background): “2005), and with theoretical models assuming a close relationship between biomass, or productivity, and environmental severity in herbaceous vegetation (Grime 1973; Michalet et al. 2006).”
Refining the stress‐gradient hypothesis for competition and facilitation in plant communities (2009, positive): “…SGH has been widely demonstrated (Callaway 2007), but for a number of reasons the ‘commonness’ ( sensu Bertness and Callaway 1994) or importance ( sensu Brooker et al. 2005) of facilitative interactions may diminish in some exceptionally stressful conditions (Michalet et al. 2006; Callaway 2007).”
A field test of the stress-gradient hypothesis along an aridity gradient (2011, background): “However, if the positive effects of benefactors wane when environmental conditions become extremely severe, plant diversity would be reduced at the most stressful end of the gradient (Michalet et al. 2006).”
Spatial scale and intraspecific trait variability mediate assembly rules in alpine grasslands (2017, background): “At small spatial grain and extent, we observed functional diversity patterns that were congruent with the stress-gradient hypothesis (Michalet et al. 2006), with more functional divergence at both low- and high-stress levels (i.e. long vs. short GSLs).”
Towards a predictive framework for biocrust mediation of plant performance: A meta‐analysis (2019, background): “…(facilitative) and negative (competitive) species interactions can determine key attributes of ecosystems such as the number of species, their distribution, and the range of species traits present within communities (Boulangeat, Gravel, & Thuiller, 2012; Michalet et al., 2006; Wisz et al., 2013).”
Allelopathy as a mechanism for the invasion of Typha angustifolia (2009, background): “Third, soluble phenolics were identified as potential allelochemicals in T. domingensis (Prindle et al. 1997; Gallardo-Williams et al. 2002) and were thought to contribute to the auto-inhibitory properties of T. latifolia ( McNaughton 1968 ).”
Aridity preferences alter the relative importance of abiotic and biotic drivers on plant species abundance in global drylands (2018, background): “Indeed, previous studies have focused on how plant-plant interactions and abiotic factors will interact to affect plant species abundance and diversity in the future (e.g., Michalet et al. 2006; Holmgren & Scheffer 2010; Soliveres & Maestre 2014; Butterfield & Munson 2016).”
Temporal shifts from facilitation to competition occur between closely related taxa (2008, background): “Empirical studies indicate that facilitative interactions increase in intensity and importance with abiotic stress, whereas negative interactions prevail under more benign conditions (Bertness & Callaway 1994; Greenlee & Callaway 1996; Hacker & Gaines 1997; Michalet et al . 2006, see discussion in”
When can positive interactions cause alternative stable states in ecosystems (2016, background): “(Michalet et al. 2006; Holmgren et al. 2012).”
Effects of facilitation on community stability and dynamics: synthesis and future directions (2009, background): “…tolerance or com- petitive ability of a species would determine the shape of its relationship between net neighbour effect and environmental severity (Michalet et al. 2006; Maestre et al. 2009), which would be the case if different species are restricted to different ranges of the potential…”
Linking individual response to biotic interactions with community structure: a trait-based framework (2009, background): “Facilitation is usually hypothesized to increase biodiversity in harsh environments (see the humpback model in Michalet et al. 2006; Callaway et al. 2002; Mulder, Uliassi, & Doak 2001) as it promotes plant types or species to persist at low abundance within stressful environments that would otherw”
Indirect facilitation promotes macrophyte survival and growth in freshwater ecosystems threatened by eutrophication (2012, background): “…may prevent the decline in species richness and abundance due to competitive exclusion and increasing competition-induced stress under eutrophication as observed along abiotic stress gradients in terrestrial ecosystems (e.g. Hacker & Gaines 1997; Michalet et al. 2006; Holmgren & Scheffer 2010).”
Strong facilitation in mild environments: the stress gradient hypothesis revisited (2010, background): “Some authors have already pointed out that in particular cases competition may overwhelm facilitative effects when conditions become very harsh (Michalet et al. 2006; Maestre et al. 2009).”
