Some #insects support passive #breathing via tracheae through #active #respiratorymovements, nsmed #convectiveventilation. Muscle contractions cause motions that e.g. dilate the #spiracles, allowing more efficient #gasexchange. The same time, the process also serves #thermoregulation. My example, the #robberfly #Tolmerus #cingulatus, demonstrates this #behavior.

Deconninck et al. provides a refreshed view of how plasticity in temperature preference can inform us about the thermoregulatory strategies of ectotherms. An all-new framework that they apply to Drosophila melanogaster.

The claim is circulating that antidepressants can cause overheating and dehydration. This is a genuine public health message, but it's not so simple: diuretics, beta blockers, ACE inhibitors, antipsychotics, and some antihistamines may also interact badly with hot weather.
https://www.nytimes.com/2024/06/15/well/live/heat-weather-medication-safety.html (excerpt in a reply)There's even doubt about antidepressants having this effect. A recent paper in eClinicalMedicine looked at all the studies they could find and concluded that there wasn't evidence of antidepressants causing overheating in hot weather - though some other medicines do.
"Current evidence supports strong anticholinergics, non-selective beta-blockers, adrenaline, and anti-Parkinson’s agents impairing thermoregulation during heat stress ... physicians should interpret with caution conventional public health messaging related to the thermoregulatory effects of some drugs (e.g., antidepressants) during hot weather."

"Across 1520 species of birds, higher temperatures are associated with longer wing bones, as predicted by Allen's Rule... we interpret the positive relationship between temperature and wing-bone length to reflect increased demand for heat dissipation in warmer climates. Our findings highlight the role of thermoregulation in shaping even the most critical features of vertebrate anatomy."

Intriguing bit in this video about ketamine + rapamycin improving heat tolerance (this is not a recommendation - I don't know enough about it)

#Bergmann's rule states that #endotherms have a large body #size in high latitudes and #cold #climates. New research suggest that whether Bergmann's rule applies to a particular taxon is mediated by not only #geographic and biological features, but also potential alternate #strategies that species might have for #thermoregulation: https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.16860?campaign=wolearlyview
