High solar radiation hinders tree regeneration above the alpine treeline in northern Ecuador (2007, positive): “Competition from surrounding vegetation could also limit tree seedling establishment (Wardle and Coleman 1992), but facilitation tends to gain relative importance in more stressful environments such as alpine areas (Callaway et al. 2002; Choler et al. 2001; Pugnaire and Lu-que 2001).”
Complementarity as a mechanism of coexistence between functional groups of grasses (2007, result): “…2006). complementarity as a mechanism of overyielding between grass species Consistent with previous studies conducted at similar altitudes (e.g. Choler et al. 2001; Callaway et al. 2002), facilitation was not detected in this study and the outcomes of biotic interactions were primarily…”
A field test of the stress-gradient hypothesis along an aridity gradient (2011, background): “For example, most tests of the SGH have considered two, rarely three, levels of environmental severity and very few have used a gradient stretching through the whole range of environmental tolerances of a species (Choler et al. 2001; Holzapfel et al. 2006).”
Interaction strengths in food webs: issues and opportunities (2004, background): “…explorations that include non-trophic links will benefit greatly from empirical work that documents the subset of potential non-trophic interactions that are observed most commonly (e.g. Menge 1995), and how they vary with environmental conditions (e.g. Choler et al. 2001; Callaway et al. 2002).”
Survival and reproduction of plant species in the Qinghai–Tibet Plateau (2014, background): “Interactions among plants have been found to be predominately positive in many high elevation communities in various locations, as the distribution, abundance, and biomass production of many species are apparently enhanced by the presence of other plant species in them (Choler et al., 2001; Callaway”
Patterns of phenotypic plasticity and local adaptation in the wide elevation range of the alpine plant Arabis alpina (2018, background): “Elevation has 43 the strongest impact above treeline on the specific and functional diversity of plant communities, with a switch from 44 interspecific competition to facilitation (Choler et al., 2001), as well as on plant physiology and morphology, with, for 45 example, the extreme case of cushion ”
Positive interactions among alpine plants increase with stress (2002, background): “This allowed us to explore interaction strengths and directions along one of the complex abiotic gradients, elevation, thought to be the most important for alpine communitie”
Interactions between marsh plant species vary in direction and strength depending on environmental and consumer context (2007, background): “Many studies have documented that the frequency of positive interactions increases in physically harsh environments (Choler et al. 2001; Holzapfel et al. 2006; Michalet et al. 2006).”
Refining the stress‐gradient hypothesis for competition and facilitation in plant communities (2009, positive): “…might be refined by incorporating species traits to explain why co-occurring species may not show the same response, either in magnitude or direction, to a common neighbour under the same environmental conditions (e.g. Callaway 1994; Choler et al. 2001; Maestre et al. 2001; Callaway et al. 2002).”
Rethinking plant community theory (2004, background): “…interactions appear to extend the upper elevational limits of many alpine plant species beyond their climate envelopes and competitive abilities (Choler et al. 2001, Callaway et al. 2002); while climate envelopes would predict that many high-altitude alpine species have the capacity to survive…”
Weak and variable relationships between environmental severity and small‐scale co‐occurrence in alpine plant communities (2007, background): “The importance of local topography for alpine plant interactions was also indicated by the results of neighbour removal experiments in sheltered vs. exposed sites at the same altitudes (Choler et al. 2001).”
