Scared and less noisy: glucocorticoids are associated with alarm call entropy.
The nonlinearity and arousal hypothesis predicts that highly aroused mammals will produce nonlinear, noisy vocalizations. We tested this prediction by measuring faecal glucocorticoid metabolites (GCMs) in adult yellow-bellied marmots (Marmota flaviventris), and asking if variation in GCMs was positively correlated with Wiener entropy-a measure of noise. Contrary to our prediction, we found a si...
متن کاملAre scared prey as good as dead?
Predators affect prey and their resources by changing the density and traits (e.g. morphology and behavior) of those prey. Ecological studies and models of community dynamics, however, typically only incorporate how changes in prey densities, rather than their traits, affect community dynamics. In a recent meta-analysis, Preisser et al. show that trait effects are as large, if not larger than d...
متن کاملSmokers are less likely than non-smokers to seek help for a lung cancer ‘alarm’ symptom
BACKGROUND The majority (>85%) of lung cancer cases are linked with smoking, and prognosis is poor because it is often diagnosed at a late stage. One contributor to late-stage diagnosis could be patient delay in help-seeking. We investigated the help-seeking behaviour of smokers and non-smokers for a recent lung cancer alarm symptom. METHODS A health survey was sent to 4913 men and women aged...
متن کاملAre Children Less Susceptible To COVID-19? A Case Series
Background The novel coronavirus (SARS-CoV-2 [2019-nCoV]) is the origin of several cases of pneumonia in Wuhan, Hubei province, China. According to the reported data, children are less common to be infected by COVID-19. Besides, their mortality rate is almost zero. Case Presentation In this article, we investigated six childr...
متن کاملNeutrophils Are Not Less Sensitive Than Other Blood Leukocytes to the Genomic Effects of Glucocorticoids
BACKGROUND Neutrophils are generally considered less responsive to glucocorticoids compared to other inflammatory cells. The reported increase in human neutrophil survival mediated by these drugs partly supports this assertion. However, it was recently shown that dexamethasone exerts potent anti-inflammatory effects in equine peripheral blood neutrophils. Few comparative studies of glucocortico...
