Gobernanza adaptativa basado en nicho ecológico. Conservación nutria neotropical en el río Suárez. Colombia

Abstract

The permanence of the Neotropical otter on the banks of the Suárez river in the limits of the departments of Boyacá and Santander was corroborated by means of indirect traces in the year 2022. In the sectors monitored in the years 2016 and 2017, where their presence was demonstrated . Through field measurements and with the help of aerial photographs, data on biophysical and anthropogenic variables of the river banks were collected, also semi-structured interviews and surveys were used to capture social information. A logistic regression model for ecological information and a dynamic model were developed to assess the current state of governance of the ecological niche of the species. It was found that the escape distance presents a positive magnitude and the distances to crops and road infrastructure present a negative magnitude in the presence of the otter. The dynamic model shows that, under the current governance conditions in the ecological niche, the relative abundance trend of the Neotropical otter is downward.
