Factors influencing survival of rescued Amazonian manatees (Trichechus inunguis) during clinical rehabilitation in Peru

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
The Amazonian manatee (Trichechus inunguis) faces threats like habitat loss, illegal hunting, and pollution. Our analysis of 54 rescued manatees in a Peruvian Amazon rehabilitation center revealed that initial weight and rate of weight gain significantly influenced survival during rehabilitation, while intestinal obstruction, often from prior ...

Unveiling Vertebrate Biodiversity in Arid and Semi‐Arid Terrestrial Ecosystems Through eDNA Metabarcoding at Savanna Waterholes

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Applying environmental DNA (eDNA) metabarcoding to samples from waterholes and their surroundings offers a promising approach for monitoring terrestrial vertebrates in semi‐arid and arid ecosystems, such as the southern African savannas. However, minimal guidance exists on key sampling design parameters for terrestrial ecosystems, which can ...

Censusing manatees: a report on the feasibility of using aerial surveys and mark and recapture techniques to conduct a population survey of the West Indian Manatee [PDF]

, 1982
This report results from an invitation to review the needs and prospects for capture-recapture and aerial census studies of the manatee (Trichechus manatus) in Florida. Three aerial reconnaissance flights provided a first hand view of manatee habitats,

Drivers of Habitat Selection by the Endangered Greater Caribbean Manatee in Coastal‐Marine Ecosystems

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Habitat selection is a fundamental aspect of animal movement and behaviour, involving strategies that influence population regulation, species interactions, community structure and the generation and preservation of biodiversity. The Greater Caribbean Manatee is a megaherbivorous aquatic mammal with high environmental plasticity, found in a ...

An approach to modeling abundance of marine wildlife over space and time using unstructured aerial surveys

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
We present an approach for estimating wildlife abundance from unstructured aerial surveys. We combine a spatial model for count data with auxiliary information on detection probability. This framework is intended to be flexible, requiring lower survey costs and less computation time than other alternatives for estimating abundance.
