In conclusion, this is the first in-depth study of ovarian
cycle in the Amazonian manatee. Our results demonstrate
that salivary samples can provide a useful tool for
endocrine monitoring in this species. Although the number
of animals analyzed was small our results suggest that
T. inunguis have peculiar hormonal patterns during the
ovarian cycle, a finding that may have physiological and
ecological significance in the reproductive strategy of these
animals.
