Distribution Patterns and Relative Abundance of Lycalopex Gymnocercus Fisher, 1814 in Southern Santa Fe Province, Argentina

Abstract The study of species diversity has become relevant due to human activities that can modify it. In Argentina, the expansion of agriculture and population growth have altered the environments of the Pampas, affecting fauna such as the gray fox. This species has historically been persecuted by hunting and conflicts with human activities, but shows adaptability to modified environments. It is native to Argentina, but was also introduced in the Falkland Islands and Tierra del Fuego. Its distribution covers a large part of Argentina and neighboring countries. In the province of Santa Fe, studies were carried out to determine its presence, distribution and habitat preference. Traces were found in xerophytic forests, halophytic communities and farmland. Presence was higher in spring and summer. Records were found both near water bodies and roads and at significant distances from them. Xerophytic forests and halophilic communities showed a higher relative abundance than croplands. The data obtained in this study contribute to the understanding of the distribution and abundance of this species in its wide range of habitats, which is essential for its conservation and the preservation of biodiversity in the ecosystems they occupy. However, it is suggested that urbanization and other factors could be affecting the species. It is important to continue monitoring and analyzing these factors for proper management of the fox population and its habitat. Keywords: Argentina, Ecology, Mammals, Santa Fe.
