INTERACTIONS BETWEEN CALVES OF AMAZONIAN MANATEES IN PERU: A STUDY CASE

Acta Biológica Colombiana, 2016
Trichechus inunguis is an endemic species of the Amazon, which inhabits mainly in lakes and calm rivers. The objective of this study case was to describe the social behaviour of two female-orphaned calves, of T. inunguis in captivity. They were kept in the same pool at the facilities of the Amazon Rescue Center (ARC, Iquitos, Peruvian Amazon).

Advances in the knowledge of the biology and conservation of the Amazonian manatee (Trichechus inunguis)

Latin American Journal of Aquatic Mammals, 2023
The last relevant work that reviewed the biological and conservation aspects of the Amazonian manatee (Trichechus inunguis) was published almost 30 years ago. In these three decades, scientific knowledge about the species has advanced substantially. This review article updates knowledge about the various biological and conservation aspects of Amazonian

Commercial feed acceptance of diets for Amazonian manatees (Trichechus inunguis) in captivity

Revista Brasileira de Higiene e Sanidade Animal, 2018
Keeping Amazonian manatees (Trichechus inunguis) in captivity is expensive and complex. Access to natural food is seasonal, and feeding manatees farmed plants is quite costly, requiring expensive logistics and planning. This study aimed to obtain alternative, good-quality feed to reduce feeding costs and decrease the risk of infectious and contagious ...

Food Plants Eaten by Amazonian Manatees (Trichechus inunguis, Mammalia : Sirenia)

Brazilian Archives of Biology and Technology, 2002
To determine the feeding habits of the Amazonian manatee Trichechus inunguis in some Central Amazonian rivers and lakes, we compared plant epidermis found in the stomach contents and/or faeces of animals with a reference collection of plants present in ...

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

Zoo Biology, Volume 45, Issue 4, Page 435-443, July/August 2026.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Changes in the blood parameters of the Amazonian manatee (Trichechus inunguis) after long-distance transportation - doi: 10.4025/actascibiolsci.v35i4.20081

Acta Scientiarum: Biological Sciences, 2013
In this study we report the hematological, biochemical and hormonal parameters in a juvenile male Amazonian manatee measured before transport, immediately after transport, and during adaptation to a new facility.

American manatees adjust their diet composition and trophic niche breadth across different coastal regions

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Marine mammals can exhibit high plasticity in foraging strategies, but how such plasticity is driven by environmental conditions is poorly understood. The American manatee (Trichechus manatus), a large, endangered herbivore, inhabits marine, estuarine, and freshwater environments.

Amazonia 2040: Spatial‐explicit futures scenarios for the mosaic of protected areas in the Lower Rio Negro (MBRN), Brazil

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Spatial‐explicit futures scenarios were applied in the Mosaic of Protected Areas of the Lower Rio Negro (MBRN), for co‐creating scenarios for the MBRN in the year 2040. Scenario making enabled negotiating desirable futures, aligning values and goals.

Surveys of environmental DNA (eDNA): a new approach to estimate occurrence in Vulnerable manatee populations

Endangered Species Research, 2018
Environmental DNA (eDNA) detection is a technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. For eDNA measurement, genetic material shed into the environment is concentrated
