Data from: Glucocorticoid levels predict subsequent social tactic in females of a facultatively social mammal

Davina Hill, Neville Pillay & Carsten Schradin
Facultatively social species, in which individuals can switch between group- and solitary-living tactics, offer an opportunity to shed light on proximate mechanisms underlying alternative life histories. Promising hormonal mediators of social tactic include glucocorticoids, which control energy allocation and are negatively related to body condition, and testosterone which regulates numerous social behaviours. Here, we investigated hormonal profiles associated with social tactic in eight generations of free-living female striped mice (Rhabdomys pumilio). Females are group living...

The fast and the curious II: performance, personality and metabolism in Karoo bush rats

Paul Agnani, Jennifer Thomson, Carsten Schradin & Vincent Careau
Personality traits (e.g., activity, exploration, boldness) are frequently correlated with each other and with various other traits of biological importance. According to the performance, allocation, and independent models of energy management, the relationship between personality traits and resting metabolic rate (RMR) is predicted to be either positive, negative, or nil. As for the relationship between personality traits and locomotor performance, the trait compensation and co-specialisation hypotheses respectively predict a positive and negative relationship. To test...

Data from: Oceanic thermal structure mediates dive sequences in a foraging seabird

Xavier Meyer, Andrew MacIntosh, André Chiaradia, Akiko Kato, Francisco Ramírez, Cedric Sueur & Yan Ropert-Coudert
1. Changes in marine ecosystems are easier to detect in upper-level predators, like seabirds, which integrate trophic interactions throughout the food web. 2. Here, we examined whether diving parameters and complexity in the temporal organisation of foraging sequences of little penguins (Eudyptula minor) are influenced by sea surface temperature (SST), water stratification and wind speed – three oceanographic features influencing prey abundance and distribution in the water column. 3. Using fractal time series analysis, we...

Van De Warrenburg, Martin Paucar, Dagmar Timmann, Ralf-Dieter Hilgers, Jose Gazulla, Michael Strupp … & Matthis Synofzik
Objective: To delineate the full phenotypic spectrum, discriminative features, piloting longitudinal progression data, and sample size calculations of RFC1-repeat expansions, recently identified as causing cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS). Methods: Multimodal RFC1 repeat screening (PCR, southern blot, whole-exome/genome (WES/WGS)-based approaches) combined with cross-sectional and longitudinal deep-phenotyping in (i) cross-European cohort A (70 families) with ≥2 features of CANVAS and/or ataxia-with-chronic-cough (ACC); and (ii) Turkish cohort B (105 families) with unselected late-onset ataxia. Results:...

Data from: Sex-specific effects of experimental ectoparasite infestation on telomere length in great tit nestlings

Barbara Tschirren, Ana Ángela Romero-Haro, Sandrine Zahn & François Cricuolo
Telomere length is a biomarker of biological ageing and lifespan in various vertebrate taxa. Evidence is accumulating that telomeres shorten more rapidly when an individual is exposed to environmental stressors. Parasites are potent selective agents that can cause physiological stress directly or indirectly through the activation of the host’s immune system. Yet to date, empirical evidence for a role of parasites in telomere dynamics in natural populations is limited. Here we show experimentally that exposure...
