Introduction
I am interested in how biotic interactions (especially plant-animal, plant-plant and plant-fungi) can shape plant communities at different scales in relation to environmental gradients. My research involves many approaches aimed at understanding the ecological consequences of global changes and disturbances. My latter focus is on plant mycorrhizal traits, trying to understand their distribution at large spatial scales, as well as their role in plant communities and ecosystems.

Article
Full-text available
Global assessments of mycorrhizal symbiosis present large sampling gaps in rich biodiversity regions. Filling these gaps is necessary to build large‐scale, unbiased mycorrhizal databases to obtain reliable analyses and prevent misleading generalizations. Underrepresented regions in mycorrhizal research are mainly in Africa, Asia, and South America....

Full-text available
The Andean paramo, hereafter “paramo”, is a Neotropical high-mountain region between the treeline and permanent snowline (3500–4800 m) and is considered the world’s coolest biodiversity hotspot. Because of paramo’s high humidity, solar radiation and temperature variation, mycorrhizal symbiosis is expected to be essential for plants. Existing theory...

Full-text available
Mycorrhizal symbioses are known to strongly influence plant performance, structure plant communities and shape ecosystem dynamics. Plant mycorrhizal traits, such as those characterising mycorrhizal type (arbuscular (AM), ecto‐, ericoid or orchid mycorrhiza) and status (obligately (OM), facultatively (FM) or non‐mycorrhizal) offer valuable insight i...

In the accompanying Comment, Weigelt et al. (2023) claim that the different conclusions of two studies—Weigelt et al. (2021) and Carmona et al. (2021)—presenting global integrations of aboveground and belowground plant traits are due to methodological issues in Carmona et al. Specifically, Weigelt et al. concluded that leaf and fine-root traits are...

Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top–down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, non‐resinous shrubs could be more influenced by herbivores than more defended, resinous shrubs. However, sparse field measurements l...
Article
Mycorrhizal symbiosis is an ancient association of plants and mycorrhizal fungi central to woody plant evolution and expansion. This symbiosis has established a complex exchange of services between plants and mycorrhizal fungi that ultimately helps plants thrive in extreme abiotic conditions and build resistance against lack of nutrients and water,...

Full-text available
Classical theory identifies resource competition as the major structuring force of biotic communities and predicts that (i) levels of dominance and richness in communities are inversely related, (ii) narrow niches allow dense “packing” in niche space and thus promote diversity, and (iii) dominants are generalists with wide niches, such that locally...

Aim Non‐native species threaten ecosystems worldwide, but we poorly know why some species invade more. Functional traits, residence time and native range size have been often used as invasion predictors. Here, we advance in the field by linking invasion success to native range parameters derived from dark diversity – a set of species present in the...

The influence of mycorrhizal symbiosis on ecosystem processes depends on the mycorrhizal type and status of plants. Early research hypothesized that the proportion of arbuscular mycorrhizal (AM) species decreases and of ectomycorrhizal (ECM) and ericoid mycorrhizal (ERM) species increases along increasing elevations and latitudes. However, there is...

Abstract Mycorrhizal symbiosis is a key relationship between most plants and certain groups of soil fungi. This interaction depends on the plant and taxa involved, describing four main plant mycorrhizal types: arbuscular mycorrhiza (AM), orchid mycorrhiza (OrM), ericoid mycorrhiza (ErM) and ectomycorrhiza (EcM). Besides, the frequency of occurrenc...
