Data from: Stratigraphic signatures of mass extinctions: ecological and sedimentary determinants

Rafał Nawrot, Daniele Scarponi, Michele Azzarone, Troy A. Dexter, Kristopher M. Kusnerik, Jacalyn M. Wittmer, Alessandro Amorosi & Michal Kowalewski
Stratigraphic patterns of last occurrences of fossil taxa (LOs) potentially fingerprint mass extinctions and delineate rates and geometries of those events. Although empirical studies of mass extinctions recognize that random sampling causes LOs to occur earlier than the time of extinction (Signor–Lipps effect), sequence-stratigraphic controls on the position of LOs are rarely considered. By tracing stratigraphic ranges of extant mollusc species preserved in the Holocene succession of the Po coastal plain (Italy), we demonstrated that,...

Data from: Combined exposure to sublethal concentrations of an insecticide and a fungicide affect feeding, ovary development and longevity in a solitary bee

Fabio Sgolastra, Xavier Arnan, Riccardo Cabbri, Gloria Isani, Piotr Medrzycki, Dariusz Teper & Jordi Bosch
Pollinators in agroecosystems are often exposed to pesticide mixtures. Even at low concentrations, the effects of these mixtures on bee populations are difficult to predict due to potential synergistic interactions. We orally exposed newly-emerged females of the solitary bee Osmia bicornis to environmentally-realistic levels of clothianidin (neonicotinoid insecticide) and propiconazole (fungicide), singly and in combination. The amount of feeding solution consumed was highest in bees exposed to the neonicotinoid, and lowest in bees exposed to...

The Atlantic bluefin tuna is a highly migratory species emblematic of the challenges associated with shared fisheries management. In an effort to resolve the species’ stock dynamics, a genome-wide search for spatially informative single nucleotide polymorphisms (SNPs) was undertaken, by way of sequencing reduced representation libraries. An allele frequency approach to SNP discovery was used, combining the data of 555 larvae and young-of-the-year (LYOY) into pools representing major geographical areas and mapping against a newly...

Data from: Molecular analysis of carnivore Protoparvovirus detected in white blood cells of naturally infected cats

Andrea Balboni, Francesca Bassi, Stefano De Arcangeli, Rosanna Zobba, Carla Dedola, Alberto Alberti & Mara Battilani
Background: Cats are susceptible to feline panleukopenia virus (FPV) and canine parvovirus (CPV) variants 2a, 2b and 2c. Detection of FPV and CPV variants in apparently healthy cats and their persistence in white blood cells (WBC) and other tissues when neutralising antibodies are simultaneously present, suggest that parvovirus may persist long-term in the tissues of cats post-infection without causing clinical signs. The aim of this study was to screen a population of 54 cats from...

Data from: Computer simulations show that Neanderthal facial morphology represents adaptation to cold and high energy demands, but not heavy biting

Stephen Wroe, William C.H. Parr, Justin A. Ledogar, Jason Bourke, Samuel P. Evans, Luca Fiorenza, Stefano Benazzi, Jean-Jacques Hublin, Chris Stringer, Ottmar Kullmer, Michael Curry, Todd C. Rae, Todd R. Yokley & William C. H. Parr
Three adaptive hypotheses have been forwarded to explain the distinctive Neanderthal face: 1) an improved ability to accommodate high anterior bite forces, 2) more effective conditioning of cold and/or dry air, and, 3) adaptation to facilitate greater ventilatory demands. We test these hypotheses using three-dimensional models of Neanderthals, modern humans, and a close outgroup (H. heidelbergensis), applying finite element analysis (FEA) and computational fluid dynamics (CFD). This is the most comprehensive application of either approach...

Data from: Plant interactions shape pollination networks via nonadditive effects

Gianalberto Losapio, Miguel A. Fortuna, Jordi Bascompte, Bernhard Schmid, Richard Michalet, Rainer Neumeyer, Leopoldo Castro, Pierfilippo Cerretti, Christoph Germann, Jean-Paul Haenni, Seraina Klopfstein, Francisco Javier Ortiz-Sánchez, Adrian C. Pont, Pascal Rousse, Jürg Schmid, Daniele Sommaggio & Christian Schöb
Plants grow in communities where they interact with other plants and with other living organisms such as pollinators. On the one hand, studies of plant–plant interactions rarely consider how plants interact with other trophic levels such as pollinators. On the other, studies of plant–animal interactions rarely deal with interactions within trophic levels such as plant–plant competition and facilitation. Thus, to what degree plant interactions affect biodiversity and ecological networks across trophic levels is poorly understood....

Data from: Validity of the Diplostomoidea and Diplostomida (Digenea, Platyhelminthes) upheld in phylogenomic analysis

Sean A. Locke, Alex Van Dam, Monica Caffara, Hudson Alves Pinto, Danimar Lopez-Hernandez & Christopher A. Blanar
Higher systematics within the Digenea, Carus 1863 have been relatively stable since a phylogenetic analysis of partial nuclear ribosomal markers (rDNA) led to the erection of the Diplostomida Olson, Cribb, Tkach, Bray, and Littlewood, 2003. However, recent mitochondrial (mt) genome phylogenies suggest this order might be paraphyletic. These analyses show members of two diplostomidan superfamilies are more closely related to the Plagiorchiida La Rue, 1957 than to other members of the Diplostomida. In one of...

Data from: Single-session tDCS over the dominant hemisphere affects contralateral spectral EEG power, but does not enhance neurofeedback-guided event-related desynchronization of the non-dominant hemisphere's sensorimotor rhythm

Valeria Mondini, Anna Lisa Mangia & Angelo Cappello
Background and objective: Transcranial direct current stimulation (tDCS) and neurofeedback-guided motor imagery (MI) have attracted considerable interest in neurorehabilitation, given their ability to influence neuroplasticity. As tDCS has been shown to modulate event-related desynchronization (ERD), the neural signature of motor imagery detected for neurofeedback, a combination of the techniques was recently proposed. One limitation of this approach is that the area targeted for stimulation is the same from which the signal for neurofeedback is acquired....

Data from: Living in two worlds: evolutionary mechanisms act differently in the native and introduced ranges of an invasive plant

Wen-Yong Guo, Carla Lambertini, Petr Pyšek, Laura A. Meyerson & Hans Brix
Identifying the factors that influence spatial genetic structure among populations can provide insights into the evolution of invasive plants. In this study, we used the common reed (Phragmites australis), a grass native in Europe and invading North America, to examine the relative importance of geographic, environmental (represented by climate here) and human effects on population genetic structure and its changes during invasion. We collected samples of P. australis from both the invaded North American and...
