Erythrocyte nuclear size as a better diagnostic character than cell size in the identification of live cryptic polyploid species.
It is well documented in anurans the cryptic condition of many species complexes involving polyploids. In these complexes the character that clearly differentiates them is the number of chromosome complements. The blood cells of amphibians conserve their nucleus, and so the erythrocyte size is correlated with the DNA content. We analyzed two cryptic-polyploid complexes occurring in the center o...
متن کاملSexual Size Dimorphism in Relation to Age and Growth in Hypsiboas cordobae (Anura: Hylidae) from Córdoba, Argentina
—Most anurans exhibit sexual size dimorphism (SSD). This morphological variation between the sexes may be attributed to different ages at maturity, growth rate, or longevity. We present the first data on age structure and growth pattern of Hypsiboas cordobae using skeletochronology, and analyze SSD considering age-specific differences in body size based on 71 individuals. Snout-vent length (SVL...

متن کاملHelminths of the frog Pleurodema diplolister (Anura, Leiuperidae) from the Caatingain Pernambuco State, Northeast Brazil.
The leiuperid genus Pleurodema (Tshudi, 1838) currently comprises 15 species widely distributed in the Neotropical region (Frost, 2011), mainly in dry forests and open areas (Ferraro and Casagranda, 2009; Kolenc et al., 2009).
