How much seagrass does a dugong need? Metabolic rate of live wild dugongs, Dugong dugon, determined through indirect calorimetry (oxygen consumption)

Marine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract Deterioration of seagrass beds worldwide has raised concern about the future of dugongs because almost all aspects of their life history depend on availability of seagrass. Understanding their energy metabolism and consequently how much seagrass they need will inform protective conservation strategies for dugongs. This study determined resting

A hybrid swarm of manatees along the Guianas coastline, a peculiar environment under the influence of the Amazon River plume

Anais da Academia Brasileira de Ciências
: The West Indian (Trichechus manatus) and Amazonian (T. inunguis) manatees have a sympatric occurrence at the mouth of the Amazon River. A result of this interspecific encounter is the occurrence of hybrids, which are frequently found along the coasts ...

Oral cleft in an Amazonian manatee (Trichechus inunguis) (Mammalia, Sirenia)

Latin American Journal of Aquatic Mammals
Since 1976, Amazonian manatees have been examined either alive or through necropsies as part of a long-term program to rescue and rehabilitate orphan manatee calves whose mothers were either victims of illegal hunting or accidental catch in fishing nets in the Brazilian Amazon region.

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

, 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
