We investigated tail-belting (TB), the newly-discovered freeze avoidance behavior among wild rodents. When temperatures dropped to -6 °C, mice (Apodemus agrarius and Apodemus flavicollis) were observed curling their tails inward positioning it on back. A literature search suggested TB had never been documented, presumably because rodents, especially in laboratory, are seldomly assayed under cold stress. Due infrequent occurrence of behavior, we used infrared thermal cameras confirm observations. also collected tail-skin samples investigate whether any physiological mechanisms might co-occur with TB. If such found, they could inform wider debate involving protection mammals, potentially lead understanding mammal susceptibility or resilience sudden temperature changes as those associated climate change. Lastly, scored behaviors by bank voles (Myodes glareolus) which unexpectedly visited chambers. Across four winters, both species during subzero conditions, but performed behavior. confirmed that occurs an adaptive reflex warms tail. From tissue samples, found free amino acids, peptides, glycoproteins significantly higher cold-stress.

These findings should inspire new dialogue regarding role lipids tissues organs mammals. By extension, our discovery a putative cryoprotection mechanism

Rodents, in particular rats and mice, are currently the most widely employed animal models psychology behavioral neuroscience. Nevertheless, an interesting historical question is: when was first rodent study performed by whom? The current article presents history of science: a case interspecies social bonding between rat dog, observed 1822 British chemist Samuel Moss (1794–1868) subsequently described same scientific 1836. In present article, after biographical sketch Moss, I examine detail notable Moss. This is under several points view. First, Moss’s albino, variety which at that time extremely rare. Moreover, time, Western world were mostly seen as pest animals or baits for rat-catching sports, not kept pets. color played key role its fate, being reason it originally brought to decided keep his care. Third, relationship arose dog even more surprising if we consider trained rat-catcher. Importantly, this rat-dog case, showcased tameness albino both lay publications, represented popularization docility rats. After having outlined considering importance our society, research (where has become prototype laboratory rat) pets, provide contextualization regarding rodents, starting from 17th century, then trace post-Moss diffusion human-bred mice 19th century.
