Bradypus variegatus (Pilosa: Bradypodidae)
Bradypus variegatus Schinz, 1825 (the brown-throated three-toed sloth), is 1 of 4 extant three-toed sloths. A highcanopy folivore, B. variegatus is distributed over southern Central America and northern and central South America and is listed as Least Concern by the International Union for Conservation of Nature and Natural Resources because of its wide distribution. Males have a middorsal spec...
متن کاملElectrocardiographic studies of the three-toed sloth, Bradypus variegatus.
Electrocardiograms (ECG) obtained with standard limb leads and augmented unipolar limb leads were recorded from 17 unanesthetized adult sloths. The animals were held in their habitual position in an experimental chair. We determined heart rate and rhythm from the R-R intervals, the amplitude and duration of each wave, and the duration of the segments and intervals of the ECG. The mean electrica...
متن کاملThe Distributional Ecology of the Maned Sloth: Environmental Influences on Its Distribution and Gaps in Knowledge
The maned sloth Bradypus torquatus (Pilosa, Bradypodidae) is endemic to a small area in the Atlantic Forest of coastal Brazil. It has been listed as a threatened species because of its restricted geographic range, habitat loss and fragmentation, and declining populations. The major objectives of this study were to estimate its potential geographic distribution, the climatic conditions across it...
متن کاملFecal estradiol and progesterone metabolite levels in the three-toed sloth (Bradypus variegatus).
The present study was carried out to assess the possibility of measuring fecal steroid hormone metabolites as a noninvasive technique for monitoring reproductive function in the three-toed sloth, Bradypus variegatus. Levels of the estradiol (E2) and progesterone (P4) metabolites were measured by radioimmunoassay in fecal samples collected over 12 weeks from 4 captive female B. variegatus sloths...
متن کاملCircadian rhythms in blood pressure in free-ranging three-toed sloths (Bradypus variegatus).
Blood pressure (BP) profiles were monitored in nine free-ranging sloths (Bradypus variegatus) by coupling one common carotid artery to a BP telemetry transmitter. Animals moved freely in an isolated and temperature-controlled room (24 degrees C) with 12/12-h artificial light-dark cycles and behaviors were observed during resting, eating and moving. Systolic (SBP) and diastolic (DBP) blood press...
