Eruption of Permanent Teeth in Japanese Monkeys (Macaca fuscata)
A total of 406 observations on dental eruption was obtained from 343 Japanese monkeys (Macaca fuscata) of known birthdays (Table 1). The order of the beginning of eruption was estimated as (M1, M1), (I1, I1), (I2, I2), (M2, M2), (PPPP), (C,, C'), (M3, M3) for male and (M1, M1), (I1, I1), (I2, I2), (M2, M2), (C,, P3, P3, C', P4, P4), (M3, M3) for female. Among 406 observations, 270 were used for...
متن کاملMolecular Demonstration of Hemotropic Mycoplasmas in Wild Japanese Monkeys (Macaca fuscata)
The prevalence of hemotropic mycoplasmas in wild monkeys is largely unknown. Here, we report the presence of hemoplasmas in blood specimens collected from wild Japanese monkeys (Macaca fuscata) tentatively captured for ecological survey in Mie prefecture, Japan. We examined 9 monkeys using hemoplasma-specific real-time PCR and found all of them positive for a hemoplasma infection. The 16S rRNA ...
متن کاملJapanese monkeys (Macaca fuscata) quickly detect snakes but not spiders: Evolutionary origins of fear-relevant animals.
Humans quickly detect the presence of evolutionary threats through visual perception. Many theorists have considered humans to be predisposed to respond to both snakes and spiders as evolutionarily fear-relevant stimuli. Evidence supports that human adults, children, and snake-naive monkeys all detect pictures of snakes among pictures of flowers more quickly than vice versa, but recent neurophy...
متن کاملFood-aversion conditioning in Japanese monkeys (Macaca fuscata): suppression of key-pressing.
Monkeys were trained in a Skinner box to press a key for standard food pellets on a fixed-ratio 10 schedule for 30 min. When stable responding had been achieved, two novel foods (almond nuts and marshmallows) were introduced. In the conditioning sessions on the odd-number days, pressing a key delivered one of the two novel foods as the to-be-conditioned target food, and each monkey was injected...
متن کاملOne-trial long-lasting food-aversion learning in wild Japanese monkeys (Macaca fuscata).
We examined how Japanese monkeys in the wild formed an aversion to food which had been paired with poison. Ten monkeys of various ages and both sexes were chosen as subjects from 105 members of the Shiga-A1 troop at Jigokudani in Shiga Heights in Japan. We gave almond nuts to each subject. Once a monkey ate 10-20 almond nuts, he was captured and moved into an injection cage. Seven experimental ...
