“…In both places, river turtle consumption and trade have been a constant source of conflicts between people and Brazilian environmental authorities, since any use of wild animals in Brazil is forbidden by law since 1967. This study is part of a long-term investigation of turtles and their (illegal) use by Rio Negro families (Pezzuti et al 2004;Rebêlo and Lugli 1996;Rebêlo and Pezzuti 2001;Rebêlo et al 2006). Created in 1980, Jaú is the second largest national park (25,350 km 2 ) in Brazil.…”

Chelonians (turtles and tortoises) of the Amazon Basin have constituted a source of food for native populations since pre-Columbian times and have continued to be an important product for subsistence and cash income. Little is known about current levels of exploitation and pressure on natural stocks, despite observations of declining populations of the larger and most valued species. This study investigates how people living in the Negro River area use Amazonian chelonians, including issues of consumption, preferences, restrictions, segmentary taboos, harmfulness, medicinal use, and sale. We conducted interviews with fishing families in the city of Barcelos and in Jaú National Park, both located in the Rio Negro basin, in the state of Amazonas, Brazil. All chelonian species are used by these riverine people, especially for food. Peltocephalus dumerilianus is caught year round, whereas the capture of other species is more frequent during the dry season. Terrestrial species are collected whenever found in the forest. Herbivorous species are preferred as food; omnivorous or carnivorous species are subject to food taboos. Two species are largely used as medicines, mainly to treat swelling and hemorrhages. Fat and epidermal scutes (scales) are widely used. At least four species are exploited commercially.

“…While commercial management of wildlife is still illegal, Ibama is reviewing existing regulations to develop criteria and procedures for the sustainable management of those species for which scientifically validated management systems have been developed. Three species of river turtle are widely hunted for their meat and eggs in the Santarém area and there is also a significant local trade in these products (Rebêlo and Pezzuti 2001;Smith 1974). Individual communities have begun guarding local turtle nesting beaches to protect females and eggs.…”

A regional experiment in co-management is underway in the Lower Amazon that is developing the basic policy and institutional elements for an ecosystem-based approach to floodplain management. This initiative grew out of the grassroots movement of floodplain communities who, concerned with excessive commercial fishing pressure on local fisheries, took control of local lakes and implemented collective agreements regulating fishing activity. This paper describes the main elements of the evolving regional management system. This process has focused on four main dimensions of floodplain settlement and resource use: development of sustainable management systems for floodplain resources, policies and institutions for fisheries co-management, collective agreements for grazing cattle on floodplain grasslands, and a land tenure policy consistent with the objectives of the evolving co-management system. Over the last year INCRA, the National Institute for Colonization and Agrarian Reform, has begun implementation of a comprehensive new land tenure policy that could resolve structural deficiencies in the existing co-management system and provide the basis for the ecosystem-based management of the Lower Amazon floodplain.Keywords Amazon Á Co-management Á Ecosystem management Á Fisheries Á Floodplain Á Varzea Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.

“…In Brazil, this freshwater turtle occurs in the Amazon Basin and Araguaia/Tocantins Basin and is popularly known as the Amazonian turtle (RUEDA-ALMONACID et al, 2007;VOGT, 2008). Podocnemis expansa has been a food resource for humans for a long time, and keeping this species in captivity as a meat source for subsistence and trade is an ancient practice among populations living along the rivers of the Amazon region (REBÊLO & PEZZUTI, 2000). However, little is known about the appropriate management of P. expansa in captivity, and it is likely that the confinement of several animals may facilitate the dissemination and persistence of parasitism (TELFORD, 1971).…”

Seventy-five turtles Podocnemis expansa in the Brazilian Amazon were examined for the presence of ectoparasites and hemoparasites. Samplings were performed in three study areas in the state of Tocantins, Brazil. Twenty-five specimens were sampled per study area (a commercial breeding facility, an indigenous subsistence breeding facility and a wild population of the Javaés River). Hemoparasites of the genus Haemogregarina were found in 66% (50/75) of the turtle specimens, and the infections were restricted to the commercial breeding facility and to the wild population of the Javaés River. The mean level of parasitemia was 54/2,000 erythrocytes (2%). There was no correlation between the body condition index of the chelonians and the level of parasitemia, with no significant difference between genders. No leeches were observed during the physical exams in any of the study areas, but the specimens from the commercial breeding facility were in poor physical condition with shell deformities and the presence of a relatively high amount of skin ulcerations, most likely caused by fungi and bacteria. This was the first study to record the occurrence of hemogregarines on a population scale in P. expansa and helps to increase knowledge about hemoparasites in chelonians in Brazil.Keywords: Podocnemis expansa, prevalence, Haemogregarina, freshwater turtle. ResumoSetenta e cinco tartarugas Podocnemis expansa foram examinadas para a presença de ectoparasitos e hemoparasitos na região amazônica brasileira. As coletas foram realizadas no Estado do Tocantins, Brasil. No estudo foram amostrados 25 indivíduos por local, um criatório comercial, um criatório de subsistência indígena e uma população silvestre do rio Javaés. Foram encontrados hemoparasitos pertencentes ao gênero Haemogregarina em 66% (50/75) dos animais, sendo que as infecções foram restritas ao criatório comercial e a população silvestre do rio Javaés. A parasitemia média foi de 54/2.000 eritrócitos (2%). Não houve relação entre o índice de condição corporal dos quelônios e os níveis de parasitemia e nem diferença quanto ao sexo dos animais. Não foram observadas sanguessugas durante os exames físicos, porém os animais do criatório comercial apresentaram condições físicas ruins com deformidades no casco e presença de uma quantidade relativamente alta de ulcerações na pele, provavelmente causadas por fungos ou bactérias. Este estudo registrou a primeira ocorrência de hemogregarinas em uma escala populacional de P. expansa e contribui para expandir o conhecimento de hemoparasitos em quelônios no Brasil.Palavras-chaves: Podocnemis expansa, prevalência, Haemogregarina, tartaruga de água doce.
