Article Synopsis
- The study focuses on the genetic analysis of the Antillean and Amazonian manatee populations in Colombia, using mitochondrial DNA from newly explored rivers and bays, revealing two new haplotypes.
- It highlights significant population differentiation between the Magdalena and Sinú rivers, potentially due to human impacts since the 16th century.
- The research also tests environmental DNA techniques for monitoring manatees, emphasizing the importance of genetic data in guiding successful conservation efforts and animal release locations.
Objective: To describe results of analysis of free-catch urine samples collected from Antillean manatees () under human care in the Caribbean.
Animals: 32 Antillean manatees in 5 Caribbean oceanaria and rescue centers.
Procedures: Urine samples were obtained by opportunistic free catch during physical examination or through the use of operant conditioning procedures.
Phylogeographic patterns and sex-biased dispersal were studied in riverine populations of West Indian (Trichechus manatus) and Amazonian manatees (T. inunguis) in South America, using 410bp D-loop (Control Region, Mitochondrial DNA) sequences and 15 nuclear microsatellite loci. This multi-locus approach was key to disentangle complex patterns of gene flow among populations.
