Consequences of dominance: a review of evenness effects on local and regional ecosystem processes. (2008, background): “…with more even distribution of traits will also be more resistant if resistance is mainly expressed by positive interactions between species, e.g., by associational resistance (Wahl and Hay 1995) or by facilitation from neighboring species (Bertness and Ewanchuk 2002, Pennings et al. 2003).”
Strain and vegetation effects on local limiting resources explain the outcomes of biotic interactions (2010, background): “Target species were likely to be facilitated if they maximized the benefits of having neighbors (low stress-tolerance) (Pennings et al., 2003), minimized their cost (high competitive response ability) (Liancourt et al., 2005), and if neighboring vegetation was able to alleviate constraining abiotic…”
STRESS TOLERANCE AND COMPETITIVE-RESPONSE ABILITY DETERMINE THE OUTCOME OF BIOTIC INTERACTIONS (2005, background): “This would explain why the species closest to its distribution optima, B. erectus, did not benefit from neighbor amelioration of soil moisture (Mulder et al. 2001, Pennings et al. 2003).”
Inclusion of biotic stress (consumer pressure) alters predictions from the stress gradient hypothesis (2009, background): “Some authors found supportive evidence (Bertness & Ewanchuk 2002; Callaway et al. 2002; Sthultz, Gehring & Whitham 2007), whereas others found evidence against it (Pennings et al. 2003; Maestre & Cortina 2004; Armas & Pugnaire 2005; Freestone 2006).”
Do individual plant species show predictable responses to nitrogen addition across multiple experiments (2005, background): “In general, low latitude salt marshes support greater biomass than high-latitude marshes, and plants at low latitudes may experience greater competition than plants at high latitudes (Pennings et al. 2003).”
Shoot, but not root, competition reduces community diversity in experimental mesocosms (2009, background): “The increase in both intensity and importance of facilitation with increasing plant community biomass and nutrient availability is counter to the Stress-Gradient-Hypothesis (SGH) (Brooker et al. 2008).”
Facilitation in plant communities: the past, the present, and the future (2007, result): “Pennings et al. (2003) failed to find support for predictions from the SGH in a study conducted over a large-scale geographical gradient in salt marshes.”
