Journal ArticleDOI
Local habitat use by botos (Amazon river dolphins, Inia geoffrensis) using passive acoustic methods
TL;DR: In this paper, the authors monitored the underwater behavior of Inia geoffrensis using stereo acoustic data loggers to observe their local habitat use and its diel changes at the Mamiraua Sustainable Development Reserve, Brazil.
Journal ArticleDOI
Endocrine monitoring of the ovarian cycle in captive female Amazonian manatees (Trichechus inunguis).
Rodrigo de Souza Amaral,Rodrigo de Souza Amaral,Fernando C. W. Rosas,Vera M. F. da Silva,Marcilio Nichi,Cláudio Alvarenga de Oliveira +5 more
TL;DR: Salivary samples can be a useful tool in the endocrine monitoring of this species and suggest that T. inunguis shows a peculiar hormonal pattern during the ovarian cycle, a finding that may have physiological and ecological significance in the reproductive strategy of these animals.
Journal ArticleDOI
Boto (Inia geoffrensis-Cetacea: Iniidae) aggregations in two provisioning sites in the lower Negro River-Amazonas, Brazil: are they related?
TL;DR: Most of the animals were unrelated within each aggregation, demonstrating that these aggregations are not normally formed due to kinship bonds, but are exclusively for feeding, as botos learn that these places provide easy access to food.
Journal ArticleDOI
Oxygenated xanthones as P-glycoprotein modulators at the intestinal barrier: in vitro and docking studies
Vera M. F. da Silva,Eva Gil-Martins,Carolina Rocha-Pereira,Agostinho Lemos,Andreia Palmeira,Ploenthip Puthongking,Emília Sousa,Maria de Lourdes Bastos,Fernando Remião,Renata Silva +9 more
TL;DR: In vitro results confirmed OXs potential for P- gp induction and/or activation and suggested SW480 cells as a suitable in vitro model for these studies, however, P-gp activation did not protected SW 480 cells against MTX cytotoxicity.
Journal ArticleDOI
Riverine people's knowledge of the Vulnerable Amazonian manatee Trichechus inunguis in contrasting protected areas
TL;DR: In this paper, the authors conducted 90 interviews with riverine people in the vicinity of Anavilhanas National Park, Tapajos-Arapiuns Extractive Reserve, and the Brazilian Amazon National Forest to increase knowledge of the feeding habits of the Amazonian manatee Trichechus inunguis.
