Nine out of ten prolonged torpor bouts occurred in individuals feeding on a low-quality diet, suggesting that pichis are able to enter prolonged periods of torpor during severe environmental stress. Five individuals entered prolonged torpor bouts lasting more than 24 h, two of them repeatedly. All individuals entered spontaneous daily torpor, but those receiving a low-quality diet had significantly lower daily mean and minimum Tsc, spent more time at Tsc below their individual lower limit of normothermia, and had a higher Heterothermy Index than controls. We recorded body temperature (Tsc) changes in 10 semi-captive, adult female pichis using dataloggers implanted subcutaneously during periods of 21 days. We experimentally tested whether food quality influences torpor frequency and depth in the pichi (Zaedyus pichiy), a small, opportunistically omnivorous armadillo endemic to arid and semi-arid habitats of southern South America. We conclude that the pichi is a true hibernator and can enter daily torpor outside of the hibernation season.ĭaily torpor is a physiological adaptation that allows mammals to cope with energetic challenges associated with unpredictable periods of food shortage. After the hibernation season, daily torpor bouts of 4 to 6 h occurred irregularly, with T(sc) dropping to as low as 24.5 degrees C. These events were interrupted by periods of euthermia of 44+/-38 h with a T(sc) of 29.1+/-0.7 degrees C. All individuals entered hibernation, characterized by torpor events of 75+/-20 h during which the subcutaneous temperature (T(sc)) decreased to 14.6+/-2.1 degrees C. We studied body temperature changes during winter in semi-captive pichis by means of temperature dataloggers implanted subcutaneously. Our objective was to determine whether the pichi (Zaedyus pichiy), a small armadillo (Xenarthra, Dasypodidae) that inhabits arid and semi-arid habitats in central and southern Argentina and Chile, enters shallow daily torpor or prolonged deep hibernation during winter when environmental temperature and food availability are low. It’s probably not the sort of response Mr Trump was hoping for as he embarks on his second summit with North Korea’s leader Kim Jong-Un.Hibernation and daily torpor are physiological strategies to cope with energetic challenges that occur in many mammalian and avian taxa, but no reliable information exists about daily torpor or hibernation for any xenarthran. CAEZA DE PICHI TVThe deluge of urine-based slurs is thanks to comedian Felipe Avello, who said in a routine on Chilean TV that he used the term to mock Mr Trump on social media.Īnd it certainly appears to be catching on, with variations of the phrase appearing prominently in the comments on all of Mr Trump’s recent Instagram posts. The phrase is used in Chilean Spanish to take the, ahem, mickey out of people with blond hair.Īnd while the proliferation of it on Mr Trump’s Instagram initially caused bewilderment to anyone outside of Chile, thankfully some clued up people were on hand to explain.Ī local comedian said that he uses to say that to Trump on social media, making a mockery out of him in our slang, basicaly cause he would never know what it means (very common way of bullying from non english spoken guys to gringos) on his live show broadcasted by rodrigoespejo February 27, 2019 Hi so Chileans are replying by the thousands go trumps insta post saying “Caez’e Pichi” which is the phonetic spelling of “piss head” in a specific Chilean accent, and I don’t understand it but I support it. He wrote: “For some beautiful reason Trump’s latest instagram post is flooded with Chileans calling him a ‘piss head’ and I could not be more excited.” The phenomenon was spotted by Twitter users including journalist Jules Suzdaltsev, who noticed scores of people commenting on the American president’s posts with variations of the phrase “cabeza de pichi”.Īnd I could not be more excited /KlyISfd1by Donald Trump has found his Instagram posts flooded with comments from Chileans calling him a “piss head”.
