Data from: Drought legacies are short, prevail in dry conifer forests and depend on growth variability.

Longares, Andrea Hevia, Miquel Tomas-Burguera & Juan Galván
The negative impacts of drought on forest growth and productivity last for several years generating legacies, although the factors that determine why such legacies vary across sites and tree species remain unclear. We used an extensive network of tree-ring width (RWI, ring-width index) records of 16 tree species from 567 forests, and high-resolution climate and NDVI datasets across Spain during the common period 1982‒2008 to test the hypothesis that climate conditions and growth features modulate...

Flowering synchrony drives reproductive success in a wind-pollinated tree

Michał Bogdziewicz, Mario Pesendorfer, Elizabeth Crone, Carlos Pérez-Izquierdo & Raul Bonal
Synchronized and quasi-periodic production of seeds by plant populations, known as masting, is implicated in many ecological processes, but how it arises remains poorly understood. Flowering and pollination dynamics are hypothesized to provide the mechanistic link for the observed relationship between weather and population‐level seed production. We report the first experimental test of the phenological synchrony hypotheses as a driver of pollen limitation in mast seeding oaks (Quercus ilex). Higher flowering synchrony yielded greater pollination...

Data from: Too salty for you? Changes of diet in the laughing gull nestlings during the growing period

Erick González-Medina, José Alfredo Castillo-Guerrero, José A. Masero & Guillermo Fernández
In many seabird and waterbird species, salinity can impose physiological stress on recently hatched chicks because they have a limited capacity to excrete salt loads. In response, parents can select low-salt food for their nestlings in the first stage of their growth. We determined the growth-related variation in the diet of laughing gull Leucophaeus atricilla nestlings by using stable isotope analysis of feathers. Isotopic measurement of hatchling down reflects the mother's diet before laying eggs....

Avian MHC copy number variation is associated with helminth richness

Piotr Minias, Jorge Gutiérrez & Peter Dunn
Genes of the Major Histocompatibility Complex (MHC) play a key role in the adaptive immunity of vertebrates, as they encode receptors responsible for recognition of antigens. Evolutionary history of the MHC proceeded through numerous gene duplications, which increases the spectrum of pathogens recognized by individuals. Although pathogen-mediated selection is believed to be a primary driver of MHC expansion over evolutionary times, empirical evidence for this association is virtually lacking. Here, we used an extensive dataset...

Data from: Pro-inflammatory immune response is linked to wintering habitat in a migratory shorebird

José Mª Abad-Gómez, Auxiliadora Villegas, Jorge S. Gutiérrez, Manuel Parejo, Juan G. Navedo, Juan M. Sánchez-Guzmán & Afonso Rocha
Migratory shorebirds (Charadrii) show a strong dichotomy in their breeding and wintering strategies: Arctic-breeding species typically spend the wintering season in marine habitats, while more southerly breeding species tend to do so in freshwater habitats where pathogens and parasites, particularly vector-borne blood parasites, are generally more abundant. Thus, it has been hypothesized that the former group may reduce their investment in immunity, but experimental data supporting this hypothesis are lacking. Moreover, whether this contrasting habitat...
