Data from: Fearlessness towards extirpated large carnivores may exacerbate the impacts of naïve mesocarnivores

Justin P. Suraci, Devin J. Roberts, Michael Clinchy & Liana Y. Zanette
By suppressing mesocarnivore foraging, the fear large carnivores inspire can be critical to mitigating mesocarnivore impacts. Where large carnivores have declined, mesocarnivores may quantitatively increase foraging, commensurate with reductions in fear. The extirpation of large carnivores may further exacerbate mesocarnivore impacts by causing qualitative changes in mesocarnivore behavior. Error management theory suggests that, where predators are present, prey should be biased towards over-responsiveness to predator cues, abandoning foraging in response to both predator cues and...

Data from: Buzz factor or innovation potential: what explains cryptocurrencies' returns?

Sha Wang & Jean-Philippe Vergne
Cryptocurrencies have become increasingly popular since the introduction of bitcoin in 2009. In this paper, we identify factors associated with variations in cryptocurrencies’ market values. In the past, researchers argued that the “buzz” surrounding cryptocurrencies in online media explained their price variations. But this observation obfuscates the notion that cryptocurrencies, unlike fiat currencies, are technologies entailing a true innovation potential. By using, for the first time, a unique measure of innovation potential, we find that...

Data from: Assortative mating but no evidence of genetic divergence in a species characterized by a trophic polymorphism

S.F. Colborne, Shawn R. Garner, Fred J. Longstaffe, Bryan D. Neff & S. F. Colborne
Disruptive selection is a process that can result in multiple subgroups within a population, which is referred to as diversification. Foraging-related diversification has been described in many taxa, but many questions remain about the contribution of such diversification to reproductive isolation and potentially sympatric speciation. Here, we use stable isotope analysis of diet and morphological analysis of body shape to examine phenotypic divergence between littoral and pelagic foraging ecomorphs in a population of pumpkinseed sunfish...

Data from: Acoustic identification of Mexican bats based on taxonomic and ecological constraints on call design

Veronica Zamora-Gutierrez, Celia Lopez-Gonzalez, M. Cristina MacSwiney Gonzalez, Brock Fenton, Gareth Jones, Elisabeth K. V. Kalko, Sebastien J. Puechmaille, Vassilios Stathopoulos & Kate E. Jones
Monitoring global biodiversity is critical for understanding responses to anthropogenic change, but biodiversity monitoring is often biased away from tropical, megadiverse areas that are experiencing more rapid environmental change. Acoustic surveys are increasingly used to monitor biodiversity change, especially for bats as they are important indicator species and most use sound to detect, localise and classify objects. However, using bat acoustic surveys for monitoring poses several challenges, particularly in megadiverse regions. Many species lack reference...

Data from: Song sparrows Melospiza melodia have a home-field advantage in defending against sympatric malarial parasites

Yanina Sarquis-Adamson & Elizabeth A. MacDougall-Shackleton
Hosts and parasites interact on both evolutionary and ecological timescales. The outcome of these interactions, specifically whether hosts are more resistant to their local parasites (sympatric) than to parasites from another location (allopatric), is likely to affect the spread of infectious disease and the fitness consequences of host dispersal. We conducted a cross-infection experiment to determine whether song sparrows (Melospiza melodia) have an advantage in dealing with sympatric parasites. We captured birds from two breeding...

Data from: Chemical composition of preen wax reflects major histocompatibility complex similarity in songbirds

Joel W.G. Slade, Matthew J. Watson, Tosha R. Kelly, Gregory B. Gloor, Mark A. Bernards, Elizabeth A. MacDougall-Shackleton & J. W. G. Slade
In jawed vertebrates, genes of the major histocompatibility complex (MHC) play a key role in immunity by encoding cell-surface proteins that recognize and bind non-self antigens. High variability at MHC suggests that these loci may also function in social signalling such as mate choice and kin recognition. This requires that MHC genotype covaries with some perceptible phenotypic trait. In mammals and fish, MHC is signalled chemically through volatile and non-volatile peptide odour cues, facilitating MHC-dependent...

Data from: Brain transcriptional profiles of male alternative reproductive tactics and females in bluegill sunfish

Charlyn G. Partridge, Matthew D. MacManes, Rosemary Knapp & Bryan D. Neff
Bluegill sunfish (Lepomis macrochirus) are one of the classic systems for studying male alternative reproductive tactics (ARTs) in teleost fishes. In this species, there are two distinct life histories: parental and cuckolder, encompassing three reproductive tactics, parental, satellite, and sneaker. The parental life history is fixed, whereas individuals who enter the cuckolder life history transition from sneaker to satellite tactic as they grow. For this study, we used RNAseq to characterize the brain transcriptome of...

Data from: NREM2 and sleep spindles are instrumental to the consolidation of motor sequence memories

Samuel Laventure, Stuart Fogel, Ovidiu Lungu, Geneviève Albouy, Pénélope Sévigny-Dupont, Catherine Vien, Chadi Sayour, Julie Carrier, Habib Benali & Julien Doyon
Although numerous studies have convincingly demonstrated that sleep plays a critical role in motor sequence learning (MSL) consolidation, the specific contribution of the different sleep stages in this type of memory consolidation is still contentious. To probe the role of stage 2 non-REM sleep (NREM2) in this process, we used a conditioning protocol in three different groups of participants who either received an odor during initial training on a motor sequence learning task and were...

Data from: The effects of dietary macronutrients on flight ability, energetics, and fuel metabolism of yellow-rumped warblers Setophaga coronata

Christopher G. Guglielmo, Alexander R. Gerson, Edwin R. Price & Quentin R. Hays
The catabolism of protein from organs and muscles during migratory flight is necessary to produce glucose, key metabolic intermediates, and water, but may have negative effects on flight range and refueling at stopovers. We tested the hypothesis, suggested by previous studies, that birds that eat high-protein insect diets use more protein for fuel in flight than those that eat high-carbohydrate fruits. First, we fed migratory yellow-rumped warblers synthetic fruit or mixed insect/fruit diets, and measured...
