Resumen
Given the high traffic and purchase of pet turtles that are subsequently abandoned within strategic and vulnerable ecosystems of our country such as the wetlands of the Bogotá savanna, this research sought to monitor the environmental and ecological characteristics of two subspecies of freshwater turtles present in the Santa María del Lago Wetland and thus assess their status and possible impact due to introduction into this new habitat. For this purpose, two samplings were carried out with a total of 22 days between the months of November and December 2020, within which a total of 70 sightings without capture of the hicotea turtle Trachemys venusta callirostris were recorded during the entire investigation, with a maximum of 7 in the same day, establishing their climatic activity ranges from 18 ° C to 22 ° C with 51% RH, in addition an adult female of 27 cm CML and 3.86 kg was captured. For its part, four specimens of the tapaculo turtle Kinosternon leucostomum postinguinale are captured, with an average CML of 141.94 mm and 0.387 kg, climatic range of 18 ° C to 23 ° C with 48% RH for this rainy transition season to dry. The use of wetland resources was detected for thermoregulation and active foraging necessary for the subsistence of these specimens with high sizes and body masses. However, there are multiple signs of immunodeficiency due to extreme environmental conditions and systemic diseases such as Septicemic Shell Ulcerative Disease (SCUD), in addition to multiple infectious trauma. Likewise, the absence of clutches or signs of reproduction for these months and the double funnel trap methods and round in water and land are found to be viable for the capture of Testudines in this wetland. Concluding that the specimens of both introduced subspecies are making use of the different resources for subsistence under the high cost of living in extreme environments, conditions that prevent their stabilization, but put native populations at risk with which they can enter into competition or predation such as the fish Eremophilus mutisii and Grundulus bogotensis reported in this study.
