Amazonian manatee critical habitat revealed by artificial intelligence-based passive acoustic techniques [PDF]

Remote Sensing in Ecology and Conservation, Volume 11, Issue 2, Page 172-186, April 2025.
For many species at risk, monitoring challenges related to low visual detectability and elusive behavior limit the use of traditional visual surveys to collect critical information, hindering the development of sound conservation strategies.

Mating Behavior of Manatees Documented in Mississippi Estuarine Waters. [PDF]

Ecol Evol
This study documents the first recorded instance of mating behavior by Florida manatees (Trichechus manatus latirostris) in Mississippi estuarine waters, observed opportunistically via a drone during a routine survey at the Grand Bay National Estuarine Research Reserve.

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.

Cranial and chromosomal geographic variation in manatees (Mammalia: Sirenia: Trichechidae) with the description of the Antillean manatee karyotype in Brazil

Journal of Zoological Systematics and Evolutionary Research, 2017
We employed landmark-based 3D geometric morphometrics to assess cranial size and shape diversification in Trichechus manatus and T. inunguis to compare it with patterns among all manatee taxa (T. manatus latirostris, T. m. manatus, T.

Coronavirus (SARS-CoV-2) in Antillean Manatees (Trichechus Manatusmanatus) [PDF]

, 2022
Abstract For two years, the world has been experiencing a coronavirus (SARS-CoV-2) pandemic. Non-human animals are susceptible to the virus, including marine mammals. Here we aimed to test Antillean manatees, Trichechus manatus manatus, for the coronavirus (SARS-CoV-2).

Unveiling the Genetic Structure of New Caledonian Dugongs Using a Multiscale Genetic Approach: Conservation Challenges for an Isolated Population. [PDF]

Ecol Evol
The small New Caledonian dugong population is geographically isolated, with extremely low mitochondrial DNA. Using mitochondrial DNA, microsatellites, and SNPs from 66 samples collected over 2 decades, we identified fine‐scale genetic structure and confirmed strong differentiation from Australian populations.

Genetic Connectivity of the West Indian Manatee in the Southern Range and Limited Evidence of Hybridization With Amazonian Manatees

Frontiers in Marine Science, 2021
The Antillean subspecies of the West Indian manatee is classified as endangered by the International Union for the Conservation of Nature (IUCN) Red List.

The initial steps toward the formation of somatic tissue banks and cell cultures derived from captive Antillean manatee (Trichechus manatus manatus) skin biopsies.

Zoo Biology, 2023
The declining population of the Antillean manatee caused by ecosystem degradation and rising pollution has prompted interest in developing conservation strategies for this species.

Rolling pits of Hartmann's mountain zebra (Zebra equus hartmannae) increase vegetation diversity and landscape heterogeneity in the Pre-Namib. [PDF]

Ecol Evol, 2021
The dust‐bathing behavior of the Hartmann’s mountain zebra creates unique rolling‐pits that persist in the landscape. In contrast to the surrounding grassland, the rolling‐pits have finer soil with higher nutrient content, collect run‐off, show a higher infiltration and keep soil moisture longer.
