Pathologic findings in manatees in Florida
Journal of the American Veterinary Medical Association
|December 1, 1984
Abstract:
Necropsy and microscopic examinations of 16 West Indian manatees (Trichechus manatus) revealed that the mortality of many of the animals was associated with environmental factors such as human-inflicted trauma and cold winters. Natural disease processes accounted for the death of only 1 manatee. In 3 manatees, the cause of death could not be determined.
Insights
Environmental factors, including human-inflicted trauma and cold winters, were the primary causes of mortality in West Indian manatees (Trichechus manatus). Natural diseases rarely caused death in the studied population.
Area of Science:
- Marine Mammal Science
- Wildlife Pathology
- Conservation Biology
Background:
- The West Indian manatee (Trichechus manatus) is a vulnerable marine mammal species facing various threats.
- Understanding mortality factors is crucial for effective conservation strategies.
Observation:
- Necropsy and microscopic examinations were performed on 16 West Indian manatees.
- The study aimed to determine the causes of death in this population.
Findings:
- Environmental factors were the leading cause of mortality in most manatees examined.
- Human-inflicted trauma and adverse weather conditions (cold winters) were significant contributing factors.
- Natural disease processes were identified as the cause of death in only one individual.
- The cause of death remained undetermined in three manatees.
Implications:
- Findings highlight the significant impact of anthropogenic and environmental stressors on manatee populations.
- Conservation efforts should prioritize mitigating human-related threats and addressing climate change impacts.
- Further research may be needed to understand undetermined mortality cases.
