Age determination in manatees using growth-layer-group counts in bone.
Mar. Mamm. Sci.
12(1): 54-88. 3 tabs. 17 figs. Jan. 2, 1996.
–Describes growth-layer groups in an enlarged sample of T. m. latirostris and T. m. manatus, showing that maximum layer counts are obtained from the middle third of the dome region (= pars temporalis or tegmen tympani) of the periotic bone, and that data from known-age, known minimum-age, and tetracycline-marked animals are consistent with annual deposition of the layers. Bone resorption does not affect accuracy of layer counts until ages greater than about 15 years and body lengths greater than 300 cm are attained. Use of layer counts from the periotic bone is considered suitable for studies of population dynamics and other age-related aspects of manatee biology.

Population viability analysis of the Florida manatee (Trichechus manatus latirostris).
Conserv. Biol.
11(2): 467-481. 3 tabs. 5 figs. Apr. 1997.
–Spanish summ. Computer modeling, based on data fron 1,212 salvaged carcasses, projects an unacceptably low probability of population persistence over 1,000 years. A 10% increase in adult mortality, or a 10% decrease in reproduction, would cause extinction within that period, whereas a 10% decrease in adult mortality would allow slow population growth. Increasing numbers of people and boats portend an increase in manatee mortality; therefore, without effective regulation of boating, the Florida manatee is likely to decline slowly to extinction.

–Portuguese & Spanish summs. Captive male manatees were found to be very deficient in zinc, magnesium, iron, potassium, and calcium, and marginally deficient in copper. Captive females were marginally deficient in copper, magnesium, iron, potassium, and calcium. The greater degree of deficiency in the males may indicate a natural difference between the sexes.

Standard of measurement among local inhabitants in the middle Solimões, occidental Amazonia, and its use in morphometrics of Amazonian manatee (Trichechus inunguis Natterer, 1883).
Uakari
6(2): 37-43. Dec. 2010.
–Portuguese summ. Measurements of the hand span (tip of thumb to tip of little finger) of 22 Amazonian manatee hunters yielded a mean value of 21.71 cm for the "palmo", the usual unit of measurement they employ for curved-line body lengths of captured manatees. This value differs from some conversion values used in the literature. In the English text of this paper, "palmo" is consistently mistranslated as "inch" rather than "span".

Occurrence of Cryptosporidium spp. in Antillean Manatees (Trichechus manatus) and Amazonian Manatees (Trichechus inunguis) from Brazil
Journal of Zoo and Wildlife Medicine
42(4):593-596.1 tab.doi: http://dx.doi.org.ezproxylocal.library.nova.edu/10.1638/2010-0216.1 2011
–ABSTRACT: Infections by Cryptosporidium spp. in aquatic mammals is a major concern due to the possibility of the waterborne transmission of oocysts. The aim of the present study was to report the occurrence of Cryptosporidium spp. in Antillean manatees (Trichechus manatus) and Amazonian manatees (Trichechus inunguis) from Brazil. Fecal samples were collected and processed using Kinyoun's method. Positive samples were also submitted to the direct immunofluorescence test. The results revealed the presence of Cryptosporidium spp. oocysts in 12.5% (17/136) of the material obtained from the Antillean manatees and in 4.3% (05/115) of the samples from the Amazonian manatees. Cryptosporidium spp. infection was more prevalent in captive animals than in free-ranging specimens.

Ingestion of invertebrates, seeds, and plastic by the Amazonian manatee (Trichechus inunguis) (Mammalia, Sirenia).
Aquatic Mammals
38(3): 322-324. DOI: 10.1578/AM.38.3.2012.322.
–ABSTRACT: The living Sirenia belong to the only group of herbivorous aquatic mammals which occur in river systems and coastal tropical and subtropical waters. From this group, the Amazonian manatee (Trichechus inunguis) is the smallest species, exclusively from fresh-water and endemic to the Amazon Basin. Sirenians are monogastric herbivores with post-gastric digestion and a low metabolic rate. Aquatic and semi-aquatic macrophytes are the main food source for Amazonian manatees, and the species composition and abundance of these plants are strongly influenced by the Amazonian hydrological pulse, which consequently influences the annual supply of food for the manatees. As accidental ingestion of microorganisms and seeds does not affect the health of the manatee even when not digested, the major concern is centered on the growing process of environmental degradation, mainly caused by indirect and direct deposition of waste in the rivers of the Amazon.
