Resumen
RENGIFO-PALACIOS, Mayra Yulenis; CETRE-MOSQUERA, Zuleiny; RENGIFO-MOSQUERA, Jhon Tailor y HALABY-GUERRERO, Julio César. Population structure and conservation status of Rhinoclemmys melanosterna Gray, J.E, 1861 (Order: Rhinoclemmys Family Geoemydidae) in ecosystems disturbed by mining in the Colombian Pacific. Bol. Cient. Mus. Hist. Nat. Univ. Caldas [online]. 2022, vol.26, n.1, pp.99-110. Epub 01-Jun-2022. ISSN 0123-3068. https://doi.org/10.17151/bccm.2022.26.1.7.
Objective:
This study aims to determine the population structure and the conservation status of the population of Rhinoclemmys melanosterna present in ecosystems disturbed by mining in the riverbed in the municipal head of Managrú.
Methodology:
Twenty samplings were carried out in bodies of water disturbed by gold mining, where traps were used to capture turtles and trawl nets.
Results:
The population of the species under study was represented by 44 individuals, 25 by means of traps and 19 by means of sweeping with trawl nets. A sampling effort of 150 hours/ man was applied to obtain a capture success of 0.02 individuals/hour trap. Similarly, by means of trawling it was 80 hours/man, and a catch success was of 0.01 individuals/hour. man. In the of R. melanosterna population was observed that males were dominant, with a 70%, which allowed significant statistical differences to exist (P-value = 0.0405). Regarding sexual dimorphism, there was no significant difference (α>0.05) in all body measurements between males and females.
Conclusion:
The females were larger than the males in all body measurements, only in the length of the tail did the males have a significantly greater length than the females.
