Dental development of Didelphis albiventris (Marsupialia): I--incisors and canines.
The formation of incisors and canines in marsupials of D. albiventris was studied at various stages of development. Seventy-six specimens, with ages varying from 0 to 100 days, were used in this investigation. Serial sections of the maxilla were obtained in the transverse plane and stained with hematoxylin and eosin. Histological analyses were made to verify the pattern of teeth development, as...
متن کاملStructural and Ultrastructural Aspects of Folliculogenesis in Didelphis albiventris, the South-American Opossum Aspectos Estructurales y Ultraestructurales de la Foliculogénesis de Didelphis albiventris, la Zarigüeña Sudamericana
The ovarian histology, the structural and the ultrastructural characteristics of the folliculogenesis in Didelphis albiventris were described in detail. Recent studies suggest that methatherian mammals have unusual reproductive cycle but there are few informations regarding the marsupials reproductive life. Despite of the opossum folliculogenesis pattern resembles methatherian and eutherian pat...
متن کاملWhich Factors Determine Spatial Segregation in the South American Opossums (Didelphis aurita and D. albiventris)? An Ecological Niche Modelling and Geometric Morphometrics Approach
Didelphis albiventris and D. aurita are Neotropical marsupials that share a unique evolutionary history and both are largely distributed throughout South America, being primarily allopatric throughout their ranges. In the Araucaria moist forest of Southern Brazil these species are sympatric and they might potentially compete having similar ecology. For this reason, they are ideal biological mod...
متن کاملMitochondrial genetic variability of Didelphis albiventris (Didelphimorphia, Didelphidae) in Brazilian localities
Didelphis albiventris is a well-known and common marsupial. Due to its high adaptability, this very widespread generalist species occurs under various environmental conditions, this even including protected regions and disturbed urban areas. We studied a 653 bp fragment of cytochrome oxidase c (COI) from 93 biological samples from seven Brazilian localities, with linear distances ranging betwee...
متن کاملHistoplasma capsulatum isolated from Didelphis albiventris (Marsupialia: Didelphidae) in the State of Minas Gerais, Brazil.
We report the isolation of Histoplasma capsulatum from a culture of the viscera of Didelphis albiventris, one of the marsupial species found in Brazil. To our knowledge, this is the first report of the isolation of this fungus from this mammalian species. This finding confirms the ubiquitous presence of H. capsulatum in nature.
