Diet of Phrynops geoffroanus (Schweigger 1812) (Chelidae) in an Environmental Protection Area in the Amazon Region of Maranhão State, Brazil
—The knowledge of the dietary composition of a species can identify important food resources for individuals and limiting resources for populations. We analyzed the dietary composition of Geoffroy’s Side-necked Turtle (Phrynops geoffroanus) by collecting stomach contents between May and November 2013. We calculated the modified Index of Relative Importance (IRI) to determine which food items we...
متن کاملHeavy metal contamination in Phrynops geoffroanus (Schweigger, 1812) (Testudines: Chelidae) in a River Basin, São Paulo, Brazil.
The Piracicaba River basin is considered the most disturbed river basin in the state of São Paulo. Considerable amounts of agricultural residues are seasonally drained into the river, and the region is also highly urbanized and industrialized with an incipient sewage treatment system. The presence of heavy metals has been previously reported for the water and riverbed in Piracicaba river basin....
متن کاملGeoffroy's side-necked turtle [Phrynops geoffroanus (Schweigger, 1812), Testudines: Chelidae] as a model for evolutionary ecotoxicology: relationship between environmental contamination, conditions and genetic variability.
The objective of this study was to evaluate the role of human activity factors, such as environmental contamination and habitat changes, as drivers for changing the physiological, biochemical, and genetic diversity of Geoffroy's side-necked turtle populations in one of the most impacted watersheds in southeastern Brazil. The impact of chemical and organic contamination was determined by ecotoxi...
متن کاملAcid phosphatase in blood smears of Phrynops geoffroanus (Testudines: Chelidae)
Claudia Regina Bonini-Domingos Acid phosphatases belong to the hydrolases class of enzymes; they act on organic esters, releasing phosphate ions in acidic conditions. These enzymes are found in lysosomes and secretory vacuoles. They are important for tissue autolysis and proliferation and differentiation and cell transformation processes, but also indicate possible tumors. Deficiency may limit ...
متن کاملEvaluation of changes in blood hematological and biochemical parameters in response to Islamic fasting and regular physical activity in male and female subjects
Introduction: Fasting during Ramadan is a religious obligation for healthy adult Muslims. This study aimed to investigate the effects of Ramadan fasting and physical activity on blood hematological and biochemical parameters in male and female subjects. Methods: In this study, 50 healthy subjects were randomly assigned to four groups: male control fasting (MCF) group (n=13), male training fasti...
