River Turtles

Turtles and their eggs have long served as an important source of food for humans—almost certainly since very early in the evolution of the hominid lineage, and surely for at least the last 20,000 years (Nicholls, 1977). Evidence in the form of shells and skeletal material (some showing burn marks as evidence of cooking) in the middens of Paleolithic aboriginal cultures, and from eyewitness accounts of explorer-naturalists in more recent times is available from numerous locations around the world (e.g., Bates, 1863; St. Cricq, 1874; Goode, 1967; Rhodin, 1992, 1995; Pritchard, 1994; Lee, 1996; Stiner et al., 1999). Skeletal evidence of river turtles, in particular from such locations as Mohenjodaro and Harappa in the Indus Valley (e.g., Indian narrow-headed softshells and river terrapins), Mayapan, and many other Mesoamerican Mayan sites (e.g., Central American river turtles), and Naga ed-Der of Upper Ancient Egypt (e.g., Nile softshell) suggest that river turtles have helped to support the rise of the world's great civilizations as well (de Treville, 1975; Nath, 1959 in Groombridge & Wright, 1982; Das, 1991; Lee, 1996). Their role continues and, in fact, has expanded as human populations have burgeoned and spread throughout the modern world. River turtles have always been too convenient and succulent a source of protein to ignore. Often large, fecund, and easily collected with simple techniques and equipment, especially in communal nesters which may concentrate at nesting sites in helpless thousands (at least formerly), river turtles are ideal prey. Much of the harvesting has been, and continues to be, conducted in relative obscurity in many parts of the world. Occasionally, however, the sheer magnitude of the resource and its slaughter has attracted the attention of literate observers, such as the early explorer-naturalists of the New and Old World tropics. Their accounts have given us some idea of the former truly spectacular abundance of some riverine species, and the equally spectacular levels of consistent exploitation which have brought them to their modern, much-diminished condition. Summaries of the exploitation of the two best documented examples of destruction of formerly abundant riverine species, the Asian river terrapin, and the giant South American river turtle, are provided under their appropriate geographic sections below.

AbstractThere is a long history of exploitation of the South American river turtlePodocnemis expansa. Conservation efforts for this species started in the 1960s but best practices were not established, and population trends and the number of nesting females protected remained unknown. In 2014 we formed a working group to discuss conservation strategies and to compile population data across the species’ range. We analysed the spatial pattern of its abundance in relation to human and natural factors using multiple regression analyses. We found that > 85 conservation programmes are protecting 147,000 nesting females, primarily in Brazil. The top six sites harbour > 100,000 females and should be prioritized for conservation action. Abundance declines with latitude and we found no evidence of human pressure on current turtle abundance patterns. It is presently not possible to estimate the global population trend because the species is not monitored continuously across the Amazon basin. The number of females is increasing at some localities and decreasing at others. However, the current size of the protected population is well below the historical population size estimated from past levels of human consumption, which demonstrates the need for concerted global conservation action. The data and management recommendations compiled here provide the basis for a regional monitoring programme among South American countries.

And Behavior

ABSTRACT During the eighteenth century, Portuguese settlers in Amazonia captured thousands of turtles and crushed millions of their eggs. These turtles, especially the Giant South American River Turtle (Podocnemis expansa), gave these settlers two essential resources: meat and oil. Though there is a rich historiography on turtle hunting, important social and environmental dimensions of the practice in Amazonia during the colonial period have been overlooked. In this paper we focus on how turtles played a key role in the diet and domestic needs of Portuguese settlers in the Amazon rainforest and explore the shape and magnitude of colonialism’s impact on these animals. The turtles became prime targets for Portuguese settlers because they were abundant and had characteristics and behavior that made them easy prey. Though P. expansa did not become extinct, Portuguese hunting had enduring impacts on their distribution and abundance that merit consideration.

ABSTRACT Leptospirosis is a zoonosis transmitted by contact with infected urine or water contaminated with the agent. Searches for Leptospira spp. in reptiles are scarce although most species have contact with aquatic environments. We evaluated the presence of anti-Leptospira spp. antibodies in Podocnemis expansa housed at the Amazonian Zoobotanical Garden, in Belém, Pará state, Brazil. We analyzed 74 serum samples through the microscopic agglutination test using 31 live antigens from different Leptospira spp. serogroups. Thirty samples (40.5%) were positive against Leptospira spp., with titrations between 100 and 3,200 for one or more serogroups. The Hebdomadis serogroup was the most prevalent, with 26 (87%) out of the 30 positive samples, followed by Djasiman, with two (7%) and Celledoni and Bataviae with one (3%) sample each. The detection of anti-Leptospira spp. agglutinins in P. expansa suggests that the aquatic environment is a transmission route for this pathogen among chelonians.
