Aim Intraspecific trait variation (ITV) within natural plant communities can be large, influencing local ecological processes and dynamics. Here, we shed light on how ITV in vegetative and floral traits responds to large-scale abiotic and biotic gradients (i.e. climate and species richness). Specifically, we tested if associations of ITV with temperature, precipitation and species richness were consistent with any of from four hypotheses relating to stress-tolerance and competition. Furthermore, we estimated the degree of correlation...

Data from: Hoopoe (Upupa epops) male feeding effort is related to female cosmetic egg colouration

Avian eggshell colouration might function as a post-mating sexually selected signal of female quality, influencing male parental investment and, hence, reproductive success. This hypothesis has been tested for intrinsic eggshell pigments as biliverdin (blue-green colouration) and/or protoporphyrin (brown coloured spots), but never for colourations applied post-laying. Post-laying staining colouration due to, for instance, uropygial secretion of the female could reflect its phenotypic properties and, thus, might be a cue for male investment in reproduction. In...

Data from: Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

Tobias Züst, Susan Strickler, Adrian Powell, Makenzie Mabry, Hong An, Mahdieh Mirzaei, Thomas York, Cynthia Holland, Pavan Kumar, Matthias Erb, Georg Petschenka, José-María Gomez, Francisco Perfectti, Caroline Mueller, Chris Pires, Lukas Mueller & Georg Jander
Phytochemical diversity is thought to result from coevolutionary cycles as specialization in herbivores imposes diversifying selection on plant chemical defenses. Plants in the speciose genus Erysimum (Brassicaceae) produce both ancestral glucosinolates and evolutionarily novel cardenolides as defenses. Here we test macroevolutionary hypotheses on co-expression, co-regulation, and diversification of these potentially redundant defenses across this genus. We sequenced and assembled the genome of E. cheiranthoides and foliar transcriptomes of 47 additional Erysimum species to construct a...

Leaf functional traits and insular colonization: subtropical islands as a melting pot of trait diversity in a widespread plant lineage

Carlos Garcia-Verdugo, Pedro Monroy, Francisco I. Pugnaire, Joana Jura-Morawiec, Xoaquín Moreira & Jaume Flexas
Aim: One of the main goals of functional biogeography is to examine distribution patterns of trait diversity, and islands provide excellent study cases for this emerging field. We tested the hypothesis that multiple dispersals from a common mainland pool would promote functional similarity among island systems when environmental conditions are similar, but also novel phenotypic traits related to colonization history and exploitation of new habitats. Location: Mediterranean Basin and Macaronesian islands Methods: We used the...

Brood parasitism, provisioning rates and breeding phenology of male and female magpie hosts

Marta Precioso, Mercedes Molina-Morales, Alfredo Sánchez-Tójar, Jesús M. Avilés & Juan G. Martínez
Parental care is a costly behaviour that raises the prospects of offspring survival. In species with biparental care these costs are shared by both parents, although there may be a conflict regarding the relative investment of each sex. Avian brood parasites leave all the costs of rearing offspring to their hosts. The magnitude of these costs and their consequences on the relative role of both sexes in parental care and future reproduction remain mostly unknown....
