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...

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....

Mt. Etna Revised and Concise Seismic Catalog from 1999 (EtnaRCSC)

The Etnean instrumental catalogue collects all the recorded earthquakes by the Permanent Seismic Network of the INGV-OE since Agoust 19, 1999. Earthquakes reported into the catalogue are localized by the analyst staff, that is, a group of people working in the seismological division, belonging to the INGV-OE. In order to produce a reliable product for the scientific community, localizations are carried out according to uniform scientific criteria shared among all analysts. Hypocentres and magnitudes of...

Data from: Protection of pepper plants from drought by microbacterium sp. 3J1 by modulation of the plant's glutamine and α-ketoglutarate content: a comparative metabolomics approach

Cristina Garcia Fontana, Juan Ignacio Vílchez & Maximino Manzanera
Desiccation-tolerant plants are able to survive for extended periods of time in the absence of water. The molecular understanding of the mechanisms used by these plants to resist droughts can be of great value for improving drought tolerance in crops. This understanding is especially relevant in an environment that tends to increase the number and intensity of droughts. The combination of certain microorganisms with drought-sensitive plants can improve their tolerance to water scarcity. One of...

Rethinking megafauna

Marcos Moleón, José Sánchez-Zapata, José Donázar, Eloy Revilla, Berta Martín-López, Cayetano Gutiérrez-Cánovas, Wayne Getz, Zebensui Morales-Reyes, Ahimsa Campos-Arceiz, Larry Crowder, Mauro Galetti, Manuela González-Suárez, Fengzhi He, Pedro Jordano, Rebecca Lewison, Robin Naidoo, Norman Owen-Smith, Nuria Selva, Jens-Christian Svenning, José Tella, Christiane Zarfl, Sonja Jähnig, Matt Hayward, Søren Faurby, Nuria García … & Klement Tochner
Concern for megafauna is increasing among scientists and non-scientists. Many studies have emphasized that megafauna play prominent ecological roles and provide important ecosystem services to humanity. But, what precisely are “megafauna”? Here we critically assess the concept of megafauna and propose a goal-oriented framework for megafaunal research. First, we review definitions of megafauna and analyze associated terminology in the scientific literature. Second, we conduct a survey among ecologists and paleontologists to assess the species traits...

Hyaenas and lions: how the largest African carnivores interact at carcasses

Mar Amorós, Jose M. Gil-Sánchez, Beatriz De Las Nieves López-Pastor & Marcos Moleón
The study of the competitive interactions between predators has traditionally been approached within the context of predatory behavior. By using a quasi-experimental, non-intrusive approach, we go beyond the classical view that predators only compete for living prey and disentangle the mechanisms of exploitative and interference competition between two charismatic apex predators, lions (Panthera leo) and spotted hyaenas (Crocuta crocuta), at carcasses other than their own kills. Carcasses of different sizes were monitored in two study...

Global gradients in intraspecific variation in vegetative and floral traits are partially associated with climate and species richness

Enquist, Carlos R. Fonseca, José M. Gómez, Antoine Guisan, Pedro Higuchi, Dirk N. Karger, Jens Kattge, Michael Kleyer, Nathan J. B. Kraft, Anne-Amélie C.

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...

Immunological changes in nestlings growing under predation risk

Gianluca Roncalli, Manuel Soler, B. Irene Tieleman, Maaike A. Versteegh, Francisco Ruiz–Raya, Elisa Colombo, Mercedes Gómez Sambla & Juan Diego Ibáñez–Álamo
Predation is one of the most relevant selective forces in nature. However, the physiological mechanisms behind anti‐predator strategies have been overlooked, despite their importance to understand predator‐prey interactions. In this context, the immune system could be especially revealing due to its relationship with other critical functions and its ability to enhance prey's probabilities of survival to a predator's attack. Developing organisms (e.g. nestlings) are excellent models to study this topic because they suffer a high...

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

Silvia Díaz Lora, Tomás Pérez-Contreras, Manuel Azcárate-García, Manuel Martínez Bueno, Juan José Soler & Manuel Martín-Vivaldi
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...
