Data from: Sensory deficiencies affect resources selection and associational effects at two spatial scales

Thomas A. Verschut, Brian D. Inouye & Peter A. Hambäck
Many insect species have limited sensory abilities and may not be able to perceive the quality of different types of resources while approaching patchily distributed resources. These restrictions may lead to differences in selection rates between separate patches and between different resource types within a patch, which may have consequences for associational effects between resources. In this study, we used an oviposition assay containing different frequencies of apple and banana substrates divided over two patches...

Data from: Resource overlap and dilution effects shape host plant use in a myrmecophilous butterfly

Alicia Valdés & Johan Ehrlén
1. The effects of consumers on fitness of resource organisms are a complex function of the spatio-temporal distribution of the resources, consumer functional responses and trait preferences, and availability of other resources. 2. The ubiquitous variation in the intensity of species interactions has important consequences for the ecological and evolutionary dynamics of natural populations. Nevertheless, little is known about the processes causing this variation and their operational scales. Here, we examine how variation in the...

Data from: Interspecific variation in ploidy as a key plant trait outlining local extinction risks and community patterns in fragmented landscapes

Jan Plue, Adam Kimberley & Tanja Slotte
1. Polyploidy is associated with a plethora of phenotypic and genetic changes yielding transformative effects on species’ life-history and ecology. These biological attributes can contribute to the success of species on ecological timescales, as observed in the invasion success or rapid environmental and climatic adaptation of polyploids. However, to date there has been a distinct lack of empirical evidence linking species’ local extinction risk, species distributions and community structure in fragmented landscapes with interspecific variation...

Data from: Interrelations of global macroecological patterns in wing and thorax size, sexual size dimorphism, and range size of the Drosophilidae

Patrick T. Rohner, Scott Pitnick, Wolf U. Blanckenhorn, Rhonda R. Snook, Gerhard Bächli & Stefan Lüpold
Support for macroecological rules in insects is mixed, with potential confounding interrelations between patterns rarely studied. We here investigate global patterns in body and wing size, sexual size dimorphism and range size in common fruit flies (Diptera: Drosophilidae) and explore potential interrelations and the predictive power of Allen's, Bergmann’s, Rensch’s and Rapoport’s rules. We found that thorax length (r2 = 0.05) and wing size (r2 = 0.09) increased with latitude, supporting Bergmann’s rule. Contrary to...

Data from: Morphological and genetic characterization of barley (Hordeum vulgare L.) landraces in the Canary Islands

Jenny Hagenblad, Matti W. Leino, Guacimara Hernández Afonso & Desirée Afonso Morales
Barley has been continuously cultivated in the Canary archipelago for millennia, and to this day landrace barley is the preferred choice for cultivation. We have morphologically and genetically characterized 57 landraces collected during the 21st century and conserved in genebanks. The majority of accessions were of the six-row type. Although landraces from the same island tended to be similar, the results showed morphological and genetic diversity both within and in the case of genetic data...

Data from: Development, characterization and comparisons of targeted and non-targeted metabolomics methods

Anton Ribbenstedt, Haizea Ziarrusta & Jonathan P. Benskin
The potential of a metabolomics method to detect statistically significant perturbations in the metabolome of an organism is enhanced by excellent analytical precision, unequivocal identification, and broad metabolomic coverage. While the former two metrics are usually associated with targeted metabolomics and the latter with non-targeted metabolomics, a systematic comparison of the performance of both approaches has not yet been carried out. The present work reports on the development and performance evaluation of separate targeted and...

Data from: Impacts of urbanization on insect herbivory and plant defences in oak trees

Xoaquín Moreira, Luis Abdala-Roberts, Jorge Berny Mier C. Y Terán, Felisa Covelo, Raúl De La Mata, Marta Francisco, Bess Hardwick, Ricardo M. Pires, Tomas Roslin, Dmitry S. Schigel, Jan P.J.G. Ten Hoopen, Bart G.H. Timmermans, Laura J.A. Van Dijk, Bastien Castagneyrol, Ayco J.M. Tack, Jorge C. Berny Mier Y Teran, Laura J. A. Van Dijk & Ayco J. M. Tack
Systematic comparisons of species interactions in urban vs. rural environments can improve our understanding of shifts in ecological processes due to urbanization. However, such studies are relatively uncommon and the mechanisms driving urbanization effects on species interactions (e.g., between plants and insect herbivores) remain elusive. Here we investigated the effects of urbanization on leaf herbivory by insect chewers and miners associated with the English oak (Quercus robur) by sampling trees in rural and urban areas...

Data from: Restoration and repair of Earth's damaged ecosystems

Holly P. Jones, Peter C. Jones, Edward B. Barbier, Ryan C. Blackburn, Jose M. Rey Benayas, Karen D. Holl, Michelle McCrackin, Paula Meli, Daniel Montoya & David Moreno Mateos
Given that few ecosystems on Earth have been unaffected by humans, restoring them holds great promise for stemming the biodiversity crisis and ensuring ecosystem services are provided to humanity. Nonetheless, few studies have documented the recovery of ecosystems globally or the rates at which ecosystems recover. Even fewer have addressed the added benefit of actively restoring ecosystems versus allowing them to recover without human intervention following the cessation of a disturbance. Our meta analysis of...

Data from: Sperm morphology and the evolution of intracellular sperm-egg interactions

Helen M. Southern, Mitchell A. Berger, Philippe G. Young & Rhonda R. Snook
Sperm morphology is incredibly diverse, even among closely related species, yet the coevolution between males and females of fertilization recognition systems is necessary for successful karyogamy (male and female pronuclear fusion). In most species, the entire sperm enters the egg during fertilization so sperm morphological diversity may impact the intra-cellular sperm-egg interactions necessary for karyogamy. We quantified morphological variation of sperm inside eggs prior to and following karyogamy in several species of Drosophila to understand...

Data from: Density-dependent positive feedbacks buffer aquatic plants from interactive effects of eutrophication and predator loss

Serena Donadi, Åsa N. Austin, Elvira Svartgren, Britas Klemens Eriksson, Joakim P. Hansen & Johan S. Eklöf
Self-facilitation allows populations to persist under disturbance by ameliorating experienced stress. In coastal ecosystems, eutrophication and declines of large predatory fish are two common disturbances that can synergistically impact habitat-forming plants by benefitting ephemeral algae. In theory, density-dependent intra-specific plant facilitation could weaken such effects, by ameliorating the amount of experienced stress. Here, we tested if and how shoot density of a common aquatic plant (Myriophyllum spicatum) alters the response of individual plants to eutrophication...

Data from: Scaling functional traits to ecosystem processes: towards a mechanistic understanding in peat mosses

Adriano Mazziotta, Gustaf Granath, Håkan Rydin, Fia Bengtsson & Jon Norberg
1. The role of trait trade-offs and environmental filtering in explaining the variability of functional traits and ecosystem processes has received considerable attention for vascular plants but less so for bryophytes. Thus, we do not know whether the same forces also shape the phenotypic variability of bryophytes. Here we assess how environmental gradients and trade-offs shape functional traits and subsequently ecosystem processes for peat mosses (Sphagnum), a globally important plant genus for carbon accumulation. We...

Data from: Simultaneous exposure to a pulsed and a prolonged anthropogenic stressor can alter consumer multifunctionality

Tiina Salo, Katja Rasanen, Christian Stamm, Francis J. Burdon & Otto Seppala
Ecosystems face multiple anthropogenic threats globally, and the effects of these environmental stressors range from individual-level organismal responses to altered system functioning. Understanding the combined effects of stressors on process rates mediated by individuals in ecosystems would greatly improve our ability to predict organismal multifunctionality (e.g. multiple consumer-mediated functions). We conducted a laboratory experiment to test direct and indirect, as well as immediate and delayed effects of a heat wave (pulsed stress) and micropollutants (MPs)...

Data from: Selection for relative brain size affects context-dependent male preferences, but not discrimination, of female body size in guppies

Alberto Corral-Lopez, Alexander Kotrschal & Niclas Kolm
Understanding what drives animal decisions is fundamental in evolutionary biology, and mate choice decisions are arguably some of the most important decisions in any individual's life. As cognitive ability can impact decision-making, elucidating the link between mate choice and cognitive ability is necessary to fully understand mate choice. To experimentally study this link, we used guppies (Poecilia reticulata) artificially selected for divergence in relative brain size and with previously demonstrated differences in cognitive ability. A...

Data from: Large-brained frogs mature later and live longer

Xin Yu, Mao Jun Zhong, Da Yong Li, Long Jin, Wen Bo Liao & Alexander Kotrschal
Brain sizes vary substantially across vertebrate taxa yet the evolution of brain size appears tightly linked to the evolution of life histories. For example, larger-brained species generally live longer than smaller-brained species. A larger brain requires more time to grow and develop at a cost of exceeded gestation period and delayed weaning age. The cost of slower development may be compensated by better homeostasis control and increased cognitive abilities, both of which should increase survival...

Data from: Selective attention by priming in host search behavior of 2 generalist butterflies

Gabriella Gamberale-Stille, Alexander Schäpers, Niklas Janz & Sören Nylin
In phytophagous insects such as butterflies, there is an evolutionary trend towards specialization in host plant use. One contributing mechanism for this pattern may be found in female host search behavior. Since search attention is limited, generalist females searching for hosts for oviposition may potentially increase their search efficacy by aiming their attention on a single host species at a time, a behavior consistent with search image formation. Using laboratory reared and mated females of...

Data from: Dogs accompanied humans during the Neolithic expansion into Europe

Morgane Ollivier, Anne Tresset, Laurent A. F. Frantz, Stéphanie Brehard, Adrian Bălășescu, Marjan Mashkour, Adina Boroneant, Maud Pionnier-Capitan, Ophelie Lebrasseur, Rose-Marie Arbogast, László Bartosiewicz, Karyne Debue, Rivka Rabinovich, Mikhail V. Sablin, Greger Larson, Catherine Hänni, Christophe Hitte & Jean-Denis Vigne
Near Eastern Neolithic farmers introduced several species of domestic plants and animals as they dispersed into Europe. Dogs were the only domestic species present in both Europe and the Near East prior to the Neolithic. Here, we assessed whether early Near Eastern dogs possessed a unique mitochondrial lineage that differentiated them from Mesolithic European populations. We then analysed mitochondrial DNA sequences from 99 ancient European and Near-Eastern dogs spanning the Upper Palaeolithic to the Bronze...

Data from: Are we underestimating the occurrence of sympatric populations?

Per Erik Jorde, Anastasia Andersson, Nils Ryman & Linda Laikre
Sympatric populations are conspecific populations that co-exist spatially. They are of interest in evolutionary biology by representing the potential first steps of sympatric speciation and are important to identify and monitor in conservation management. Sympatric existence in freshwater habitats can be more easily defined than terrestrial ones, and a series of sympatric fish populations have been reported. Reviewing the literature pertaining to sympatric populations of salmonid fishes, we find that most cases of sympatry appear...
