Abstract: Predation and alteration of microhabitats may represent high risk for nesting of Amazonian turtles. This study aimed at investigating the nesting and body parameters of neonates of Podocnemis unifilis in the Araguari River basin, State of Amapá, Brazil. The spawning sites of this turtle were monitored along the Falsino River (a region with two reserves) and in the urban area of the Porto Grande city along the Araguari River, from August to December 2011. A total of 180 nests were found and the nesting occurred… Show more

“…In the Amazon, meat, viscera and turtle eggs are important sources of protein for riverine and indigenous populations, but are appreciated by urban human communities due to the cultural habit maintained by generations of riverine origin (Duarte et al 2008). Thus, P. unifilis population has a long history of decline due to the use of its meat and eggs by riverine communities, as well as by pressure on its nesting habitats (Arraes and Tavares-Dias, 2014). Pantoja-Lima et al (2014) estimated that about 34 tons of turtles are consumed annually only along the margins of a major fishing river in the state of Amazonas, central Amazon (Brazil).…”

“…In the Araguari river basin (eastern Amazon), the nesting of P. unifilis occurs from September to November, eggs hatching occurrs in December and the mean incubation period is of 63.5 ± 5.2 days. In this region, the urban population growth and changes of P. unifilis habitat, due to the exploitation of pebbles on the riverbed and constructions of hydroelectric power plant may be causing changes in nesting patterns, not yet evaluated (Arraes and Tavares-Dias, 2014). Thus, the present study has compared the human impact effects on nesting patterns and body characteristics of P. unifilis neonates in areas of forest reserves (region of low impact) and urban area (region of high impact) in this important basin for the northern Brazil.…”

“…The yellow-spotted river turtle Podocnemis unifilis Troschel 1848, is a semi-aquatic turtle widely distributed in South America (Arraes and Tavares-Dias, 2014). In the literature, there are few reports of pathogens affecting these turtle species, being the hemogregarines hemoparasites commonly reported (Soares et al 2014;Espinoza et al 2017).…”
