Aim: Plant recruitment involves both stochastic and deterministic processes. Recruits may establish independently or interact
nonrandomly with canopy plants. We explore this deterministic aspect by testing whether recruitment patterns are influenced
by the phylogenetic history of canopy and recruiting plants. Since the effect of canopy plants in recruitment can be positive
(facilitation), negative (competition) or neutral, we also estimated the phylogenetic signal separately for each interaction type.
Furthermore, we assessed whether environmental stress influenced the phylogenetic signal, under the expectation that more
severe environmental conditions will lead to stronger phylogenetic signatures in network structure.
Location: Global.
Time Period: 1998–2021.
Major Taxa Studied: Angiospermae.
Methods: We analysed recruitment interactions occurring in 133 plant communities included in the RecruitNet database, which
encompasses a wide range of biomes and vegetation types. The phylogenetic signal in canopy–recruit interactions was quantified
in different dimensions of the recruitment niche, represented by the level of interaction generalisation, and by the taxonomic and
evolutionary composition of the group of canopy plants.
Results: We found significant phylogenetic signals in more networks than expected by chance. Canopies’ evolutionary history
influenced facilitative and competitive but not neutral interactions. The phylogenetic signal in the recruitment niche strengthened
in arid regions, suggesting that stressful habitats promote the occurrence of conserved recruitment interactions where
closely related species recruit in association with closely related canopy species.
Main Conclusions: Despite the strong influence of stochastic processes on plant recruitment, evolutionary history plays a significant
role in driving the recruitment process, especially in harsh environments. In particular, the historical effect becomes more important when canopy species have a significant impact on the performance of recruits, either through facilitation or competition.
More generally, we show that the analysis of different dimensions of the ecological niche can reveal important insights
on the functional roles of interacting species.
