Data from: Trait anticipatory pleasure predicts effort expenditure for reward

Joachim T. Geaney, Michael T. Treadway & Luke D. Smillie
Research in motivation and emotion has been increasingly influenced by the perspective that processes underpinning the motivated approach of rewarding goals are distinct from those underpinning enjoyment during reward consummation. This distinction recently inspired the construction of the Temporal Experience of Pleasure Scale (TEPS), a self-report measure that distinguishes trait anticipatory pleasure (pre-reward feelings of desire) from consummatory pleasure (feelings of enjoyment and gratification upon reward attainment). In a university community sample (N = 97),...

Data from: Inclusive fitness and differential productivity across the life course determine intergenerational transfers in a small-scale human society

Paul L. Hooper, Michael Gurven, Jeffrey Winking & Hillard S. Kaplan
Transfers of resources between generations are an essential element in current models of human life-history evolution accounting for prolonged development, extended lifespan and menopause. Integrating these models with Hamilton's theory of inclusive fitness, we predict that the interaction of biological kinship with the age-schedule of resource production should be a key driver of intergenerational transfers. In the empirical case of Tsimane’ forager–horticulturalists in Bolivian Amazonia, we provide a detailed characterization of net transfers of food...

Data from: Restoring Study 329: efficacy and harms of paroxetine and imipramine in treatment of major depression in adolescence

Joanna C. Le Noury, John M. Nardo, David Healy, Jon Jureidini, Melissa Raven, Catalin Tufanaru & Elia Abi-Jaoude
Objectives: To reanalyse SmithKline Beecham’s Study 329 (published by Keller and colleagues in 2001), the primary objective of which was to compare the efficacy and safety of paroxetine and imipramine with placebo in the treatment of adolescents with unipolar major depression. The reanalysis under the restoring invisible and abandoned trials (RIAT) initiative was done to see whether access to and reanalysis of a full dataset from a randomised controlled trial would have clinically relevant implications...

Data from: Disease ecology across soil boundaries: effects of below-ground fungi on above-ground host–parasite interactions

Leiling Tao, Camden D. Gowler, Aamina Ahmad, Mark D. Hunter & Jacobus C. De Roode
Host–parasite interactions are subject to strong trait-mediated indirect effects from other species. However, it remains unexplored whether such indirect effects may occur across soil boundaries and connect spatially isolated organisms. Here, we demonstrate that, by changing plant (milkweed Asclepias sp.) traits, arbuscular mycorrhizal fungi (AMF) significantly affect interactions between a herbivore (the monarch butterfly Danaus plexippus) and its protozoan parasite (Ophryocystis elektroscirrha), which represents an interaction across four biological kingdoms. In our experiment, AMF affected...

Data from: Evaluation of Blue Crab, Callinectes sapidus, megalopal settlement and condition during the Deepwater Horizon oil spill

Erin K. Grey, Susan C. Chiasson, Hannah G. Williams, Victoria J. Troeger & Caz M. Taylor
The Blue Crab, Callinectes sapidus, is a commercially, culturally, and ecologically significant species in the Gulf of Mexico (GOM), whose offshore stages were likely impacted by the Deepwater Horizon oil spill (DWH). To test for DWH effects and to better understand the planktonic ecology of this species, we monitored Callinectes spp. megalopal settlement and condition at sites within and outside of the spill extent during and one year after the DWH. We tested for DWH...

Data from: Awake fMRI reveals a specialized region in dog temporal cortex for face processing

Daniel D. Dilks, Peter F. Cook, Samuel K. Weiller, Helen P. Berns, Mark Spivak, Gregory S. Berns & Peter Cook
Recent behavioral evidence suggests that dogs, like humans and monkeys, are capable of visual face recognition. But do dogs also exhibit specialized cortical face regions similar to humans and monkeys? Using functional magnetic resonance imaging (fMRI) in six dogs trained to remain motionless during scanning without restraint or sedation, we found a region in the canine temporal lobe that responded significantly more to movies of human faces than to movies of everyday objects. Next, using...

Data from: Diffusion tensor imaging of dolphin brains reveals direct auditory pathway to temporal lobe

Gregory S. Berns, Peter F. Cook, Sean Foxley, Saad Jbabdi, Karla L. Miller & Lori Marino
The brains of odontocetes (toothed whales) look grossly different from their terrestrial relatives. Because of their adaptation to the aquatic environment and their reliance on echolocation, the odontocetes' auditory system is both unique and crucial to their survival. Yet, scant data exist about the functional organization of the cetacean auditory system. A predominant hypothesis is that the primary auditory cortex lies in the suprasylvian gyrus along the vertex of the hemispheres, with this position induced...

Data from: The evolution of reduced antagonism – a role for host-parasite coevolution

Amanda Kyle Gibson, Kayla S. Stoy, Ian A. Gelarden, McKenna J. Penley, Curtis M. Lively & Levi T. Morran
Why do some host-parasite interactions become less antagonistic over evolutionary time? Vertical transmission can select for reduced antagonism. Vertical transmission also promotes coevolution between hosts and parasites. Therefore, we hypothesized that coevolution itself may underlie transitions to reduced antagonism. To test the coevolution hypothesis, we selected for reduced antagonism between the host Caenorhabditis elegans and its parasite Serratia marcescens. This parasite is horizontally transmitted, which allowed us to study coevolution independently of vertical transmission. After...

Data from: Algal toxin impairs sea lion memory and hippocampal connectivity, with implications for strandings

Peter F. Cook, Colleen Reichmuth, Andrew A. Rouse, Laura A. Libby, Sophie E. Dennison, Owen T. Carmichael, Kris T. Kruse-Elliott, Josh Bloom, Baljeet Singh, Vanessa A. Fravel, Lorraine Barbosa, Jim J. Stuppino, William G. Van Bonn, Frances M. D. Gulland & Charan Ranganath
Domoic acid (DA) is a naturally occurring neurotoxin known to harm marine animals. DA-producing algal blooms are increasing in size and frequency. Although chronic exposure is known to produce brain lesions, the influence of DA toxicosis on behavior in wild animals is unknown. We showed, in a large sample of wild sea lions, that spatial memory deficits are predicted by the extent of right dorsal hippocampal lesions related to natural exposure to DA and that...

Data from: An overrepresentation of high frequencies in the mouse inferior colliculus supports the processing of ultrasonic vocalizations

Jose A. Garcia-Lazaro, Kathryn N. Shepard, Jason A. Miranda, Robert C. Liu & Nicholas A. Lesica
Mice are of paramount importance in biomedical research and their vocalizations are a subject of interest for researchers across a wide range of health-related disciplines due to their increasingly important value as a phenotyping tool in models of neural, speech and language disorders. However, the mechanisms underlying the auditory processing of vocalizations in mice are not well understood. The mouse audiogram shows a peak in sensitivity at frequencies between 15-25 kHz, but weaker sensitivity for...

Data from: Fruit flies diversify their offspring in response to parasite infection

Nadia D. Singh, Dallas R. Criscoe, Shelly Skolfield, Kathryn P. Kohl, Erin S. Keebaugh & Todd A. Schlenke
The evolution of sexual reproduction is often explained by Red Queen dynamics: Organisms must continually evolve to maintain fitness relative to interacting organisms, such as parasites. Recombination accompanies sexual reproduction and helps diversify an organism’s offspring, so that parasites cannot exploit static host genotypes. Here we show that Drosophila melanogaster plastically increases the production of recombinant offspring after infection. The response is consistent across genetic backgrounds, developmental stages, and parasite types but is not induced...

Data from: Vomiting as a symptom and transmission risk in norovirus illness: evidence from human challenge studies

Amy E. Kirby, Ashleigh Streby & Christine L. Moe
Background: In the US, noroviruses are estimated to cause 21 million cases annually with economic losses reaching $2 billion. Outbreak investigations frequently implicate vomiting as a major transmission risk. However, little is known about the characteristics of vomiting as a symptom or the amount of virus present in emesis. Methodology and Principal Findings: Emesis samples and symptomology data were obtained from previous norovirus human challenge studies with GI.1 Norwalk virus, GII.2 Snow Mountain virus, and...
