Spatial and temporal heterogeneity in pollinator communities maintains within-species floral odour variation

Mark A. Szenteczki, Adrienne Godschalx, Andrea Galmán, Anahí Espíndola, Marc Gibernau, Nadir Alvarez & Sergio Rasmann
Flowering plants emit complex bouquets of volatile organic compounds (VOCs) to mediate interactions with their pollinators. These bouquets are undoubtedly influenced by pollinator-mediated selection, particularly in deceptively-pollinated species that rely on chemical mimicry. However, many uncertainties remain regarding how spatially and temporally heterogeneous pollinators affect the diversity and distribution of floral odour variation. Here, we characterized and compared the floral odours of ten populations of deceptively-pollinated Arum maculatum (Araceae), and inter-annual and decadal variation in...

A meta‐analysis of insularity effects on herbivory and plant defences

Xoaquín Moreira, Bastien Castagneyrol, Carlos García‐Verdugo & Luis Abdala‐Roberts
Aim: Plants on islands are often subjected to lower levels of herbivory relative to those at mainland sites. As a consequence, island plants are predicted to exhibit lower levels of physical and chemical defences, which renders them more susceptible to introduced herbivores. Yet, instances of high pressure by superabundant herbivores native to islands have been reported in many insular systems, which presumably would result in heightened plant defences. To date, no quantitative review has been...

Plant species-specificity of ant-plant mutualistic interactions: Differential predation of termites by Camponotus crassus on five species of extrafloral nectaried plants

Eduardo Calixto, Denise Lange, Xoaquín Moreira & Kleber Del-Claro
There is increasing evidence that the outcomes of mutualistic interactions between ants and plants bearing extrafloral nectaries (EFNs) is context-dependent. In particular, the total number, density and size of EFNs, as well as the abundance and identity of ants attending host plants, are considered as key factors determining the nature and strength of ant-EFN-bearing plant interaction. Although many previous studies have investigated context-dependency in ant–plant protection mutualisms mediated by EFNs, few have tested whether the...

Plant defence syndromes on islands

Xoaquín Moreira
Aim: It has been hypothesised that insular plant taxa have evolved reduced defences in response to lower herbivore pressure on islands. However, the few studies testing this hypothesis have addressed variation in individual defensive traits, without paying attention to patterns of correlated trait expression (i.e. defence syndromes). Location: Balearic and Canary Islands. Taxon: Ninety-one woody plant species. Methods: We tested whether plant species with contrasting histories of insularity (namely: endemics, non-endemic natives, and exotics) differed...

Data from: Urbanization affects oak–pathogen interactions across spatial scales

Laura Van Dijk, Xoaquin Moreira, Anna Barr, Luis Abdala-Roberts, Bastien Castagneyrol, Maria Faticov, Bess Hardwick, Jan Ten Hoopen, Raul De La Mata, Ricardo Matheus Pires, Tomas Roslin, Dmitry Schigel, Bart Timmermans & Ayco Tack
The world is rapidly urbanizing, thereby transforming natural landscapes and changing the abundance and distribution of organisms. However, insights into the effects of urbanization on species interactions, and plant-pathogen interactions in particular, are lacking. We investigated the effects of urbanization on powdery mildew infection on Quercus robur at continental and within-city scales. At the continental scale, we compared infection levels between urban and rural areas of different-sized cities in Europe, and investigated whether plant traits,...
