Data from: The potential of electricity transmission corridors in forested areas as bumblebee habitatBruce Hill & Ignasi Bartomeus
Declines in pollinator abundance and diversity are not only a conservation issue, but also a threat to crop pollination. Maintained infrastructure corridors, such as those containing electricity transmission lines, are potentially important wild pollinator habitat. However, there is a lack of evidence comparing the abundance and diversity of wild pollinators in transmission corridors with other important pollinator habitats. We compared the diversity of a key pollinator group, bumblebees (Bombus spp.), between transmission corridors and the...
Data from: Tackling intraspecific genetic structure in distribution models better reflects species geographical rangeArnald Marcer, Belén Méndez-Vigo, Carlos Alonso-Blanco & F. Xavier Picó
Genetic diversity provides insight into heterogeneous demographic and adaptive history across organisms’ distribution ranges. For this reason, decomposing single species into genetic units may represent a powerful tool to better understand biogeographical patterns as well as improve predictions of the effects of GCC (global climate change) on biodiversity loss. Using 279 georeferenced Iberian accessions, we used classes of three intraspecific genetic units of the annual plant Arabidopsis thaliana obtained from the genetic analyses of nuclear...
Data from: Relationships among taxonomic, functional, and phylogenetic ant diversity across the biogeographic regions of EuropeXavier Arnan, Xim Cerdá & Javier Retana
Understanding how different biodiversity components are related across different environmental conditions is a major goal in macroecology and conservation biogeography. We investigated correlations among alpha and beta taxonomic (TD), phylogenetic (PD), and functional diversity (FD) in ant communities in the five biogeographic regions most representative of western Europe; we also examined the degree of niche conservatism. We combined data from 349 ant communities composed of 154 total species, which were characterized by 10 functional traits...
Data from: Cascading effects of defaunation on the coexistence of two specialized insect seed predatorsGuille Peguero, Helene C. Muller-Landau, Patrick A. Jansen & S. Joseph Wright
Identification of the mechanisms enabling stable coexistence of species with similar resource requirements is a central challenge in ecology. Such coexistence can be facilitated by species at higher trophic levels through complex multi-trophic interactions, a mechanism that could be compromised by ongoing defaunation. We investigated cascading effects of defaunation on Pachymerus cardo and Speciomerus giganteus, the specialized insect seed predators of the Neotropical palm Attalea butyracea, testing the hypothesis that vertebrate frugivores and granivores facilitate...
Data from: Phenological asynchrony in plant–butterfly interactions associated with climate: a community-wide perspectiveIsabel Donoso, Constanti Stefanescu, Alejandro Martínez-Abraín & Anna Traveset
Although much information has been accumulated on the effects of climate change on particular species worldwide, research aimed at assessing how such change influences biotic interactions from a community-wide perspective is still in its infancy. We contribute to filling in this gap by analyzing a 17-year (1996–2012) dataset that includes records of flower-visitation interactions between 12 butterfly species and 17 plant species in a coastal wetland area in northeastern Iberian Peninsula. We assessed the extent...
Large brains (relative to body size) might confer fitness benefits to animals. Although the putative costs of well-developed brains can constrain the majority of species to modest brain sizes, these costs are still poorly understood. Given that the neural tissue is energetically expensive and demands antioxidants, one potential cost of developing and maintaining large brains is increased oxidative stress (‘oxidation exposure’ hypothesis). Alternatively, because large-brained species exhibit slow-paced life histories, they are expected to invest...
Data from: Shade tolerance and the functional trait - demography relationship in temperate and boreal forestsAitor Ameztegui, Alain Paquette, Bill Shipley, Michael Heym, Christian Messier & Dominique Gravel
Despite being instrumental in forest ecology, the definition and nature of shade tolerance are complex and not beyond controversy. Moreover, the role it plays in the trait – demography relationship remains unclear. Here, we hypothesize that shade tolerance can be achieved by alternative combinations of traits depending on the species’ functional group (evergreen vs. deciduous species), and that its ability to explain the array of traits involved in demography will also vary between these two...
Plants store large amounts of non-structural carbohydrates (NSC). While multiple functions of NSC have long been recognized, the interpretation of NSC seasonal dynamics is often based on the idea that stored NSC is a reservoir of carbon that fluctuates depending on the balance between supply via photosynthesis and demand for growth and respiration (the source-sink dynamics concept). Consequently, relatively high NSC concentrations in some plants have been interpreted to reflect excess supply relative to demand....
Data from: Towards a common methodology for developing logistic tree mortality models based on ring-width dataMaxime Cailleret, Christof Bigler, Harald Bugmann, J. Julio Camarero, Katarina Cufar, Hendrik Davi, Ilona Mészáros, Francesco Minunno, Mikko Peltoniemi, Elisabeth Robert, María-Laura Suarez, Roberto Tognetti & Jordi Martinez-Vilalta
Tree mortality is a key process shaping forest dynamics. Thus, there is a growing need for indicators of the likelihood of tree death. During the last decades, an increasing number of tree-ring based studies have aimed to derive growth–mortality functions, mostly using logistic models. The results of these studies, however, are difficult to compare and synthesize due to the diversity of approaches used for the sampling strategy (number and characteristics of alive and death observations),...
