Interspecific facilitation mediates the outcome of intraspecific interactions across an elevational gradient

Raath-Kruger, Morgan J.; Schob, Christian; McGeoch, Melodie A.; Le Roux, Peter Christiaan (Ecological Society of America, 2021-01)

Where interspecific facilitation favors the establishment of high densities of a beneficiary species, strong intraspecific competition may subsequently impede beneficiary performance. Consequently, the negative influence ...
Positive plant–plant interactions expand the upper distributional limits of some vascular plant species

Raath-Kruger, Morgan J.; Mcgeoch, Melodie A.; Schob, Christian; Greve, Michelle; Le Roux, Peter Christiaan (Ecological Society of America, 2019-08)

Biotic interactions can shape species’ distributions through their impact on species’ realized niches, potentially constraining or expanding the range of conditions under which species occur. We examine whether fine-scale ...
A robust mixed-effects parametric quantile regression model for continuous proportions : quantifying the constraints to vitality in cushion plants

Burger, Divan Aristo; Van der Merwe, Sean; Lesaffre, Emmanuel; Le Roux, Peter Christiaan; Raath-Kruger, Morgan J. (Wiley, 2023-11)

There is no literature on outlier-robust parametric mixed-effects quantile regression models for continuous proportion data as an alternative to systematically identifying and eliminating outliers. To fill this gap, ...
