Occurrence of Antibodies toToxoplasma gondiiandLepstospiraspp. in Manatees (Trichechus inunguis) of the Brazilian Amazon

Journal of Zoo and Wildlife Medicine, 2012
The presence of Toxoplasma gondii and Leptospira spp. antibodies was investigated in 74 manatees (Trichechus inunguis [Mammalia: Sirenia]) kept in captivity in two rescue units in the northern region of Brazil. Antibodies to T gondii were detected in 29 (

Growth curve of free-ranging Trichechus inunguis [PDF]

Biota Neotropica, 2010
The objective of this work was to describe growth curves for free-ranging Amazonian manatees in Brazil. Data analyzed included age estimates and biometrics from 60 Amazonian manatees (33 males and 27 females) captured between 1993 and 2006 by local residents of the mid-Solimões and Pirativa Rivers, in Amazonia, and collected by the Instituto de ...

Metabolism and Respiration of the Amazonian Manatee (Trichechus inunguis)

Physiological Zoology, 1980
A study was made of respiration and metabolism in Amazonian manatees (Trichechus inunguis) weighing between 20 and 170 kg. These animals had a low metabolic rate, 0.36 times that predicted by Kleiber's 1975 equation for placental mammals. They also had a low breathing frequency and minute ventilation, and high O₂ extraction and CO₂ output.

Sleep in an Amazonian manatee,Trichechus inunguis

Experientia, 1992
For the first time, sleep was studied in a representative of the order of Sirenia. Slow wave sleep occupied 27%, and paradoxical sleep 1% of the total recording time in the Amazonian manatee. Trichechus inunguis. The circadian rhythmicity of sleep was pronounced.

Noninvasive Monitoring of Androgens in Male Amazonian Manatee (Trichechus inunguis): Biologic Validation

Journal of Zoo and Wildlife Medicine, 2009
The Amazonian manatee (Trichechus inunguis) is endemic in the Amazonian basin and is the only exclusively fresh water sirenian. Historically hunted on a large scale, this species is now considered endangered, and studies on the reproductive physiology are critical for the improvement of reproductive management of captive and wild populations of ...

Temperature Regulation in the Amazonian Manatee Trichechus inunguis

Physiological Zoology, 1983
The mean core temperatures (Tc) of two Amazonian manatees (Trichechus inunguis) were 35.6 ± 0.1 C (X ± SD) and 36.1 ± 0.2 C at ambient water temperatures (Tw = 27–29 C). Based on metabolic rate (MR), the lower critical water temperature (TLC) of the larger manatee was 22-23 C. Above TLC, Tc varied with Tw, but the animal maintained Tc below TLC.
