Dear Colleagues,
We are pleased to announce our new publication:
Suárez-Achaval, R.G., Serrano, A., Chamorro-Florescano, I. et al. Characterization
of Antillean manatee (Trichechus manatus manatus) habitat and resources availability in the Alvarado Lagoon System, Veracruz. Eur
J Wildl Res 69, 10 (2023). https://doi.org/10.1007/s10344-022-01639-x
Abstract
Historically, the Antillean manatee (Trichechus manatus manatus) was distributed along the coastline comprised by
the five Mexican states that border the Gulf of Mexico. However, the few healthy populations that currently exist in Mexico are now limited to relatively isolated regions with very specific habitat characteristics. In the state of Veracruz, a limited number
of individuals are found in the Alvarado Lagoon System (ALS), located in the coastal zone of southern central Veracruz. The aim of this study was to characterize manatee habitat in the ALS. Transects were established in the ALS and 503 points selected and
sampled along these transects, producing data pertaining to salinity, depth, dissolved oxygen, total dissolved solids, surface water temperature, pH, bottom type, and conductivity. A total of 45 outings were conducted, with a total sampling effort of 332.36 h.
The average physicochemical parameters found were as follows: salinity 3.33 ppm, total dissolved solids 0.51 g/l, temperature 26.29 °C, dissolved oxygen 0.51%, pH 7.55, and oxidation–reduction potential 417.04 mV. Thirteen manatees were observed, mostly (84.6%)
during the cold, where the parameters of electrical conductivity, salinity, total dissolved solids, dissolved oxygen, temperature, and oxidation–reduction potential showed differences between the sampled seasons, and in the lagoons with a presence of the floating
and submersible vegetation species that form part of manatees’ diet. This study shows that the ALS presents lagoons that favor the presence of the Antillean manatee, further narrowing the distribution of the species within the same ALS in the southern central
zone of the state of Veracruz.
