Unifying facilitation and recruitment networks

Ecological network studies are providing important advances about the organization, stability and dynamics of ecological systems. However, the ecological networks approach is being integrated very slowly in plant community ecology, even though the first studies on plant facilitation networks were published more than a decade ago. The study of interaction networks between established plants and plants recruiting beneath them, which are called Recruitment Networks (RNs), can provide new insights on mechanisms driving plant community structure and dynamics. RNs basically describe which plants recruit under which others, so they can be seen as a generalisation of the classic Facilitation Networks (FNs) since they do not imply any particular effect (positive, negative or neutral) of the established plants on recruiting ones. RNs summarise information on the structure of sapling banks. More importantly, the information included in RNs can be incorporated into models of replacement dynamics to evaluate how different aspects of network structure, or different mechanisms of network assembly, may affect plant community stability and species coexistence. To allow an efficient development of the study of FNs and RNs, here concepts were unified, current knowledge was synthesised, some conceptual issues were clarified, and basic methodological guidelines were proposed to standardise sampling methods that could make future studies of these networks directly comparable. Moreover, interested researchers are invited to collaborate in a global database of recruitment networks that is being built until the end of 2020, using the sampling protocols and recommendations provided.

Disentangling the abundance–impact relationship for invasive species

To predict the threat of biological invasions to native species, it is critical to understand how increasing abundance of invasive alien species affects native populations and communities. The form...

Coexistence between sympatric carnivores in a Mediterranean habitat

One of the main objectives of community ecology is to understand the conditions allowing species to coexist. However, few studies have investigated the role of fine-scale habitat use segregation in...
