Acute necrotizing colitis with pneumatosis intestinalis in an Amazonian manatee calf

Diseases of Aquatic Organisms, 2016
On 25 January 2014, a 1 mo old female Amazonian manatee Trichechus inunguis calf weighing 12 kg was rescued by air transport in Guajará, Brazil, and transferred to Mamirauá Institute's Community-based Amazonian Manatee Rehabilitation Center. The calf presented piercing/cutting lesions on the back, neck, and head, in addition to dehydration and ...

Acoustic tagging for counting feeding events of captive Amazonian manatees

The Journal of the Acoustical Society of America, 2012
The Amazonian manatee is one of four extant species in the mammalian order Sirenia. They are restricted to the freshwater rivers, lakes and floodplains of the Amazonian river basin where they eat floating and emergent aquatic plants. Visual observation of wild manatees is nearly impossible because of the turbid water and tiny exposure of nose at gentle

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 ...

Apparent Dry-Season Fasting in Amazonian Manatees (Mammalia: Sirenia)

Biotropica, 1983
Amazonian manatees (Trichechus inunguis), restricted to deep water areas in the larger lakes in the central Amazon during the dry season, do not have any obvious food sources until water levels rise between 1-2 m. Evidence from Lago Amana suggests almost seven months of fasting.

Blood parameters of the amazonian manatee (Trich echus inunguis)—dietary variation

Comparative Biochemistry and Physiology Part A: Physiology, 1992
Abstract 1. 1. No significant differences (P > 0.05) were found between the blood parameters of male and female Amazonian manatees. 2. 2. When water hyacinth was introduced into the animals' diet, there was a significant difference (P 0.05) in glucose and urea concentrations. 3. 3.

Eimeria trichechi n.sp. from the Amazonian manatee, Trichechus inunguis (Mammalia: Sirenia)

Systematic Parasitology, 1983
Eimeria trichechi n.sp. is described and figured from the manatee, Trichechus inunguis, from Amazonas State, north Brazil. Undifferentiated oocysts are passed in the faeces and complete their sporulation in ∼36h at 24 to 26°C. Oocysts are spherical, with a mean size of 13.40 × 13.30 μm.

Biology, conservation and status of the Amazonian Manatee Trichechus inunguis

Mammal Review, 1994
AbstractThe Amazonian Manatee Trichechus inunguis (Natterer, 1883) is the only exclusively freshwater sirenian and the smallest of the living species. Its inability to reduce peripheral heat loss limits its distribution to tropical waters. The species is endemic to the Amazonian region, being distributed throughout the Amazon basin, occurring mainly in

RENAL FUNCTION PARAMETERS OF HEALTHY CAPTIVE AND SEMICAPTIVE AMAZONIAN MANATEES (TRICHECHUS INUNGUIS)

Journal of Zoo and Wildlife Medicine
Evaluating renal function is essential for managing captive wild animals, particularly threatened species like the Amazonian manatee (Trichechus inunguis) in rehabilitation and prerelease programs. A series of urine diagnostic tests, such as gross appearance, semiquantitative chemical analyses, microscopic review of sediments, and quantitative analyses

Endocrine monitoring of the ovarian cycle in captive female Amazonian manatees (Trichechus inunguis)

Animal Reproduction Science, 2013
The Amazonian manatee (Trichechus inunguis; Mammalia: Sirenia), a threatened aquatic mammal endemic to the Amazon basin, is the only sirenian that lives exclusively in fresh water. Information about the reproductive endocrinology of the Amazonian manatee is scarce; therefore, the aim of this study was to monitor salivary progesterone and estradiol ...
