Manatees display diel trends in acoustic activity at two microhabitats in Belize. [PDF]
PLoS ONE, 2023 Many marine mammals exhibit diel trends in vocal production, which can provide information on habitat use and behavioral activity. In Belize, Antillean manatees (Trichechus manatus manatus) commonly inhabit small depressions in the substrate or deep ...

Diet composition of the African manatee: Spatial and temporal variation within the Sanaga River Watershed, Cameroon. [PDF]
Ecol Evol, 2021 Due to a large knowledge gap on diet and seasonal changes in forage availability, this study aims to investigate the diet of threatened African manatees to better inform conservation decisions within protected areas of Cameroon. We analyzed 113 manatee fecal samples and surveyed shoreline emergent and submerged vegetation within the Sanaga River ...

African manatee (Trichechus senegalensis) habitat suitability at Lake Ossa, Cameroon, using trophic state models and predictions of submerged aquatic vegetation. [PDF]
Ecol Evol, 2021 Little information exists on the water quality and health of the aquatic ecosystem within protected areas in Cameroon. We monitor water quality in Lake Ossa, a refuge for the threatened African manatee, and find considerable eutrophication and poor water transparency.
