Functional traits of young seedlings predict trade‐offs in seedling performance in three neotropical forests

Journal of Ecology, Volume 111, Issue 12, Page 2568-2582, December 2023., 2023
With strikingly consistent patterns across three tropical forests, the authors find strong evidence for the promise of functional traits to provide mechanistic links between seedling form and demographic performance. Abstract Understanding the mechanisms that promote the coexistence of hundreds of species over small areas in tropical forest remains a ...

Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse

Conservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

Climatic and biogeographical drivers of functional diversity in the flora of the Canary Islands

Global Ecology and Biogeography, Volume 31, Issue 7, Page 1313-1331, July 2022., 2022
Abstract Aim Functional traits can help us to elucidate biogeographical and ecological processes driving assemblage structure. We analysed the functional diversity of plant species of different evolutionary origins across an island archipelago, along environmental gradients and across geological age, to assess functional aspects of island ...

Seed fate in ant‐mediated dispersal: Seed dispersal effectiveness in the Ectatomma ruidum (Formicidae)—Zanthoxylum ekmanii (Rutaceae) system

Biotropica, Volume 54, Issue 3, Page 764-775, May 2022., 2022
Using the seed dispersal effectiveness framework, we tracked seed fate in a dispersal limited system finding that ant workers (Formicidae, Ectatomma ruidum) act as secondary dispersers for the pioneer tree Zanthoxylum ekmanii (Rutaceae) whose seeds have no visible adaptation for ant dispersal.

Variation of non‐structural carbohydrates across the fast–slow continuum in Amazon Forest canopy trees

Functional Ecology, Volume 36, Issue 2, Page 341-355, February 2022., 2022
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Tropical tree species span a range of life‐history strategies within a fast–slow continuum. The position of a species within this continuum is thought to reflect a negative relationship between growth and storage, with fast‐growing species allocating ...
