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 کامل
Anaesthetic Effect of Propofol on Rainbow Trout (Oncorhynchus Mykiss) in Two Different Concentrations
Objective- The study aims to determine efficacy of propofol as an inmersión agent to induce anesthesia in rainbow trout (Oncorhynchus mykiss). Design- Experimental study. Animals- 36 healthy rainbow trout Procedure- Trouts were sorted ramdomly in two groups, 18 fish each one. Both groups were anesthesized by bath, one of them with 2,5 mg/l, the other one at 5 mg/l concentratio...متن کامل
Sexual 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 کامل
Pleurodema guayapae is a species that inhabits saline environments and semidesert zones from central Argentina. To date, the knowledge about the reproductive biology of this species is very poor, and our aim is to contribute to its knowledge with the description of some important reproductive aspects. For this, field work was undertaken in an area near to Patquia, La Rioja province. Sampling wa...متن کامل
