Neighbor density‐dependent facilitation promotes coexistence and internal oscillation

Neighbor density‐dependent facilitation promotes coexistence and internal oscillation

Buche, L., Shoemaker, L.G., Vesk, P., Hallett, L.M., Godoy, O. & Mayfield, M.

Ecological Monographs, 95(4), 2025

We developed a new way to quantifying pairwise interactions along a spectrum from facilitation to competition, acording to different non-linear functions. For the asymptotic density-dependent functions, we found that facilitation by low-density neighbouring species enhances coexistence, aligning theoretical predictions with natural observations. We tested this methodology on Lawrencella rosea, an Australian native daisy found on the land of the Dadimaya people in Western Australia.

A continuum from positive to negative interactions drives plant species' performance in a diverse community

A continuum from positive to negative interactions drives plant species' performance in a diverse community

Buche, L., Shoemaker, L., Hallett, L., Vesk, P., Weiss-Lehmann, C., Bartomeus, I., Mayfield, M. & Godoy, O.

Ecology Letters, 2025

We explored the patterns of species performance, dependent on species interaction strengths and higher-order interactions with species belonging to the same and other trophic levels. We found that a continuum from positive to negative interactions, containing mostly guild-level effects and a few strong taxonomic-specific effects, was sufficient to describe plant performance.

Multitrophic higher-order interactions modulate species persistence

Buche, L., Bartomeus, I. & Godoy, O.

The American Naturalist, 2024

We showed the importance of multispecies interactions in inferring species persistence. A third species can change the nature (sign and strength) of a pairwise interaction (i.e., higher-order interactions). While such interactions are traditionally ignored, we show that higher-order interactions promote the opportunities for multispecies communities to persist compared with a scenario without multispecies interactions.

Non-random interactions within and across guilds shape the potential to coexist in multitrophic ecological communities

Non-random interactions within and across guilds shape the potential to coexist in multitrophic ecological communities

Garcia-Callejas, D., Godoy, O., Buche, L., Hurtado, M., Lanuza, J.B., Allen-Perkins, A. & Bartomeus, I.

Ecology Letters, 2023

Species persistence depends on the structure of their biotic interactions. The results show that biotic interactions within and across guilds are not random in nature. Considering natural complexity, such as community richness, increases the potential for species to persist and form complex communities thanks to self-regulation and niche-partitioning.

Niche differences, not fitness differences, explain predicted coexistence across ecological groups

Niche differences, not fitness differences, explain predicted coexistence across ecological groups

Buche, L., Spaak, J.W., Jarillo, J. & De Laender, F.

Journal of Ecology, 1–12, 2022

Based on a meta-analysis of species interactions across taxa, we show the importance of niche differentiation as a mechanism for pairwise coexistence. The coexistence of two species is assessed based on their ability to differentiate along their niche and fitness axes. We show that their difference along the niche axis is more related to coexistence than along their fitness axis.
