Acid 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 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 کاملDiet 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 کاملA taxonomic reevaluation of Phrynops (Testudines: Chelidae) with the description of two new genera and a new species of Batrachemys.
Relationships among turtle species loosely categorized within the South American genus Phrynops are explored. Three once recognized genera (Batrachemys, Mesoclemmys and Phrynops) that were demoted to subgenera, and then synonymized with Phrynops, are demonstrated to warrant full recognition based on morphometric analysis, skull osteology, and mitochondrial and nuclear gene sequencing. Mesoclemm...
