Database of the occurrence of the species Mesoclemmys perplexa, Mesoclemmys tuberculata, and Phrynops geoffroanus in Brazil

Latin American Data in Science
Databases provide organization and storage of information, whether biological or ecological, to facilitate access to data about species. Therefore, the objective of this study was to present a database on the distribution of Mesoclemmys perplexa, M. tuberculata, and Phrynops geoffroanus, which will be available to the scientific community. To build the

Sexual dimorphism and biometric patterns of Phrynops geoffroanus in a Protected Wetland of northeastern Amazonia, Brazil

Brazilian Journal of Animal and Environmental Research
Sexual dimorphism is widely reported in freshwater turtles and is often associated with differences in reproductive strategies and life-history traits. We investigated sexual dimorphism, biometric relationships, and sex ratio in a population of Phrynops geoffroanus inhabiting Lake São Francisco, located within the Environmental Protection Area of ...
