Interaction Between Traditional Fishers and the Neotropical Otter Lontra longicaudis (Olfers, 1818) in a Brazilian Amazon Estuary

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT The neotropical otter Lontra longicaudis (Olfers, 1818) is a semi‐aquatic carnivore from the Mustelidae family with a piscivorous habit that interacts with riverine populations because of fishing resources, and this relationship is often negative, especially in the Amazon where fishing represents an important activity for several communities ...

Occupancy and population density estimates of the Amazonian manatee in eastern Ecuador

Endangered Species Research, 2021
The Amazonian manatee Trichechus inunguis has been categorized as Vulnerable by the IUCN. There have been few studies on the species in its natural habitats due to its elusive nature and the low visibility of its aquatic habitats.

Global importance of Amazonian freshwaters

Frontiers in Ecology and the Environment, Volume 23, Issue 10, December 2025.
Amazonian freshwaters have large influences on regional and global climate, harbor remarkable and unique species, and are vital to human society. Nevertheless, as compared to their terrestrial counterparts in the Amazon, these freshwaters have received less attention from the international conservation community.

Historical Collections of Tropical Marine Mammals Are an Excellent Resource for Ancient DNA

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT The ability to predict ancient DNA sequencing success in natural history collections is critical to reducing the amount of destructive sampling of a finite resource. So far, studies investigating such success have predominantly focused on taxa with ranges restricted to temperate or cold environments at northern latitudes, which likely aids DNA

Prioritizing future evidence needs for marine and freshwater mammal conservation action

Animal Conservation, Volume 28, Issue 4, Page 542-552, August 2025.
To improve conservation practice, decisions should be informed by the available evidence on the effectiveness of conservation actions. Here, we review the comprehensiveness of this evidence base for marine and freshwater mammals. We assess the taxonomic and geographic coverage of the evidence base, identify biases and suggest priorities for future ...

Amazonian manatee critical habitat revealed by artificial intelligence‐based passive acoustic techniques

Remote Sensing in Ecology and Conservation, Volume 11, Issue 2, Page 172-186, April 2025.
We developed a method combining passive acoustic monitoring and convolutional neural networks to automatically detect the presence of Amazonian manatees in a floodplain lake over two flooded seasons. The CNN model showed a high performance (98% average precision) and was applied to process 226 days of acoustic recordings.

Cultivated Manatee Meat Aiding Amazon Biodiversity Conservation: Discussing a Proposed Model

Conservation, 2023
Cultivated meat (CM) is a disruptive technology that provides an alternative to animal protein. In this context, the Amazon manatee (Trichechus inunguis) emerges as an important case.
