Data from: Quantifying temporal change in plant population attributes: insights from a resurrection approach

Rocío Gómez, Belen Mendez-Vigo, Arnald Marcer, Carlos Alonso-Blanco & F. Xavier Picó
Rapid evolution in annual plants can be quantified by comparing phenotypic and genetic changes between past and contemporary individuals from the same populations over several generations. Such knowledge will help understand the response of plants to rapid environmental shifts, such as the ones imposed by global climate change. To that end, we undertook a resurrection approach in Spanish populations of the annual plant Arabidopsis thaliana that were sampled twice over a decade. Annual weather records...

Data from: Global geographic patterns in the colours and sizes of animal‐dispersed fruits

Miranda A. Sinnott-Armstrong, Alexander E. Downie, Sarah Federman, Alfredo Valido, Pedro Jordano & Michael J. Donoghue
Aim. Fruit colours attract animal seed dispersers, yet the causes of fruit colour diversity remain controversial. The lack of knowledge of large-scale spatial patterns in fruit colours has limited our ability to formulate and test alternative hypotheses to explain fruit colour, fruit size, and fruit colour diversity. We describe spatial (especially latitudinal) variation in fruit colour, colour diversity, and length, and test for correlations between fruit colour, length, and plant habit. Location. Global. Time period....

Complex long-term dynamics of pollinator abundance in undisturbed Mediterranean montane habitats over two decades

Carlos M. Herrera
Current notions of “pollinator decline” and “pollination crisis” mainly arose from studies on pollinators of economic value in anthropogenic ecosystems of mid-latitude temperate regions. Comprehensive long-term pollinator data from biologically diverse, undisturbed communities are needed to evaluate the actual extent of the so-called “global pollination crisis”. This paper analyzes the long-term dynamics of pollinator abundance in undisturbed Mediterranean montane habitats using pollinator visitation data for 65 plant species collected over two decades. Objectives are (1)...

Data from: Melanin-based sexual dichromatism in the Western Palearctic avifauna implies darker males and lighter females

Juan J. Negro, Enrique Figueroa-Luque & Ismael Galván
Melanins are the most common pigments providing coloration in the plumage and bare skin of birds and other vertebrates. Numerous species are dichromatic in the adult or definitive plumage, but the direction of this type of sexual dichromatism (i.e., whether one sex tends to be darker than the other ones) has not been thoroughly investigated. Using color plates, we analysed the presence of melanin-based color patches in 666 species belonging to 69 families regularly breeding...

Data from: Spatial prioritisation of EU’s LIFE-Nature program to strengthen the conservation impact of Natura 2000

Virgilio Hermoso, Dani Villero, Miguel Clavero & Lluís Brotons
1. Despite advances in conservation efforts within Europe during recent decades, assessments highlight a need for adequate financing mechanisms to support the Natura 2000 network; the centrepiece of the EU´s Biodiversity Strategy. Besides the need for greater investment (currently only covering a fifth of the estimated cost of the network), better planning for this investment could help better achieve conservation goals. 2. We demonstrate a method that could be used to identify priority Natura 2000...

Data from: An overlooked plant-parakeet mutualism counteracts human overharvesting on an endangered tree

Karina L. Speziale, Sergio A. Lambertucci, Gabriela Gleiser, José L. Tella, Fernando Hiraldo & Marcelo A. Aizen
The exponential growth of the human population often causes the overexploitation of resources and disruption of ecological interactions. Here we propose that the antagonist effect of humans on exploited species might be alleviated with the advent of a second predator species. We focused on the complex interactions between an endangered conifer (Araucaria araucana) and two seed exploiters: the Austral parakeet (Enicognathus ferrugineus) and human seed collectors. We tested the importance of partial seed consumption by...

Data from: Integrating genomic and phenotypic data to evaluate alternative phylogenetic and species delimitation hypotheses in a recent evolutionary radiation of grasshoppers

Víctor Noguerales, Pedro Javier Cordero & Joaquín Ortego
Although resolving phylogenetic relationships and establishing species limits is a primary goal of systematics, these tasks remain challenging at both conceptual and analytical levels. Here, we integrated genomic and phenotypic data and employed a comprehensive suite of coalescent-based analyses to develop and evaluate competing phylogenetic and species delimitation hypotheses in a recent evolutionary radiation of grasshoppers (Chorthippus binotatus group) composed of two species and eight putative subspecies. To resolve the evolutionary relationships within this complex,...

Data from: Tracking data and retrospective analyses of diet reveal the consequences of loss of marine subsidies for an obligate scavenger, the Andean condor

Sergio A. Lambertucci, Joan Navarro, Jose Antonio Sánchez-Zapata, Keith A. Hobson, Pablo A.E. Alarcón, Guillermo Wiemeyer, Guillermo Blanco, Fernando Hiraldo & Jose Antonio Donazar
Over the last century, marine mammals have been dramatically reduced in the world’s oceans. We examined evidence that this change caused dietary and foraging pattern shifts of the Andean condor (Vultur gryphus) in Patagonia. We hypothesized that, after the decrease in marine mammals and the increase in human use of coastlines, condor diet changed to a more terrestrial diet which, in turn, influenced their foraging patterns. We evaluated the diet by means of stable isotope...

Data from: Stochastic and deterministic effects on interactions between canopy and recruiting species in forest communities

Julio M. Alcantara, Manuel Pulgar, Kristian Trøjelsgaard, José L. Garrido & Pedro J. Rey
1. Interactions between established (canopy) and recruiting individuals (recruits) are pervasive in plant communities. Studies on recruitment in forests have mainly focused on negative density-dependent conspecific interactions, while the outcomes of heterospecific canopy-recruit interactions have received much less attention and are generally assumed to be driven by stochastic processes. 2. Herein, we explore the relative influence of stochastic (abundance) and deterministic (species identity and phylogenetic distance) effects on the frequency of canopy-recruit interactions, and characterise...

Data from: MHC-mediated sexual selection on bird song: generic polymorphism, particular alleles and acoustic signals

László Z. Garamszegi, Magdalena Zagalska-Neubauer, David Canal, György Blázi, Miklós Laczi, Gergely Nagy, Eszter Szöllősi, Éva Vaskuti, János Török & Sándor Zsebők
Several hypotheses predict that the major histocompatibility complex (MHC) drives mating preference in females. Olfactory, color or morphological traits are often found as reliable signals of the MHC profile, but the role of avian song mediating MHC-based female choice remains largely unexplored. We investigated the relationship between several MHC and acoustic features in the collared flycatcher (Ficedula albicollis) a European passerine with complex songs. We screened a fragment of the class IIB 2nd exon of...

Data from: Factors associated with leucism in the common blackbird (Turdus merula)

Lucía Izquierdo, Robert L. Thomson, José I. Aguirre, Alazne Díez-Fernández, Bruno Faivre, Jordi Figuerola & Juan Diego Ibáñez-Álamo
Leucism is the total or partial lack of melanins in the skin and associate structures (i.e. hair or feathers). Little is known about the factors influencing this chromatic aberration although some local studies suggest that there is an effect of habitat, age and sex. To test these hypotheses and expand our knowledge on leucism, we carried out a large‐scale study using common blackbirds (Turdus merula) as our model species. Given the poor information available on...
