Two Evoflor’s members (José María Gómez and Rubén Torices) in collaboration with John Pannell from University of Lausanne have recently published a paper in Nature Communications showing that the self-incompatible monocarpic Moricandia moricandioides can adjust its flowering behaviour to the surrounding intraspecific social environment.
Individuals growing with kin, particularly at high density, produced larger floral displays than those growing with non-kin. Investment in attracting pollinators was thus moulded by the presence and relatedness of neighbours, exemplifying the importance of kin recognition in the evolution of plant reproductive strategies. Therefore, this study now provides evidence that investment towards attracting pollinators includes a component of neighbour relatedness, a necessary consequence of the fine spatial genetic structure of plant populations.
In addition, these results suggest that floral strategies might have also been shaped by selection through their indirect effects on inclusive fitness, i.e., through the success of relatives. This possibility was foreshadowed by Hamilton and has long been appreciated by zoologists.
We present in this paper a molecular phylogeny of the genus Moricandia (Brassicaceae). We have found that a Spanish population previously ascribed to Rytidocarpus moricandioides is indeed a Moricandia species, and we propose to name it as M. rytidocarpoides sp. nov. In addition, M. foleyi appeared outside the Moricandia lineage but within the genus Eruca. Therefore, M. foleyi should be excluded from the genus Moricandia and be ascribed to the genus Eruca.

A core interest in studies of mutualistic interactions is the ‘effectiveness’ of mutualists in providing benefits to their partners. In plant-animal mutualisms it is widely accepted that the total effect of a mutualist on its partner is estimated as (1) a ‘quantity’ component multiplied by (2) a ‘quality’ component, although the meanings of ‘effectiveness,’ ‘quantity,’ and ‘quality’ and which terms are applied to these metrics vary greatly across studies. In addition, a similar quantity × quality = total effect approach has not been applied to other types of mutualisms, although it could be informative. Lastly, when a total effect approach has been applied, it has invariably been from a phytocentric perspective, focussing on the effects of animal mutualists on their plant partner. This lack of a common framework of ‘effectiveness’ of mutualistic interactions limits generalisation and the development of a broader understanding of the ecology and evolution of mutualisms.

In a paper recently published in Plant Biology, we have identified environmental differences between niches occupied by diploids and tetraploids Erysimum mediohispanicum.
To evaluate the adaptive significance of the geographic distribution of cytotypes, we characterized the ploidy level of 118 populations across the Iberian Peninsula and obtained their interpolated climate variables from the Worldclim 1.4. In addition, we also characterized floral phenotype of both cytotypes. Read more
Included in Annals of Botany‘s special issue on developmental robustness and species diversity, our papers nalyzes the role of pollinators in the evolution of the phenotypic variation, disparity and integration of the corolla shape of 111 Brassicaceae taxa. Read more
Our paper “The temporal dimension in individual-based plant pollination networks” has been published in Oikos. In this paper we present the temporal changes occurring in a pollination network established between individuals of the extremely generalist herb Erysimum mediohispanicum (Brassicaceae). Read more
