Um estudo biogeográfico da Ave Anhima cornuta (Linnaeus, 1766), na Comunidade Divino Espirito Santo - Parintins/AM

Abstract

The research carried out is in the field of biogeography, a scientific area that investigates the geographic distribution of life forms on Earth, by merging knowledge from Biology and Geography. Understanding the factors that influence the reason why a certain species thrives in a specific area, through the study of the bird, Anhima cornuta, popularly known as gongon, is the objective of this work. The aim is to fill gaps in knowledge about the species and contribute valuable insights to establish a database in the region of Parintins/AM, precisely in the rural community of Divino Espírito Santo. The interest in deepening knowledge about the bird's ecology, its eating and reproductive habits, phylogenetic evolution, among others, motivated this investigation, to achieve the research objectives. Descriptive and comparative methods were used in field research, with informal conversations with residents and incorporating observation techniques within the community to locate the bird, within a perimeter of the study area. The collaboration of residents, especially fishermen, was important for understanding bird sightings and their way of life. Reducing the number of individuals of the species was also possible with the collaboration of the community's inhabitants. An alert was made for this reduction due to problems such as predatory hunting for recreational purposes, the impact of such human activities and, possibly, the issue of climate change that will dry up the floodplain lakes, the peculiar habitat of these birds. Therefore, there is a need for responsible practices to prevent the decline of species and maintain ecological balance in the region.
