In this regard, information on the Boa constrictor is still rather scarce. To achieve a successful breeding season, thorough knowledge of the females’ reproductive activity is necessary. The Boa constrictor is one of the most common reptiles bred in captivity. Results suggest that this technique allows an accurate monitoring of the captive female boas’ reproductive cycle, as well as a precise control of the embryos’ development and viability. A group of captive-bred female boa constrictors were monitored by ultrasound over an entire breeding season. In this regard, knowledge of the Boa constrictor is rather scarce. Currently, ultrasonography is the most common technique used in veterinary medicine for evaluating reproductive activity in both mammals and reptiles. In order to achieve the proper management of boas in captivity, it is essential to have in-depth knowledge on the reproduction of this species and to identify minimally invasive methods for a correct monitoring of the reproductive cycle and gestation, guaranteeing the animal’s welfare. With the exception of one subspecies, the Boa constrictor is now included in Appendix II of the Convention on International Trade of Endangered Species (C.I.T.E.S.). These snakes can be found in tropical South America, as well as some islands in the Caribbean. The growing interest in snakes has led to an increase in captive-bred ophidians, and the Boa constrictor is one of the most common reptiles bred in captivity. These results constitute useful information that may assist managers in decision making during critical events provided by the operationally proposed type modeling.In recent years, reptiles have become increasingly popular pets. And that the predictability especially in Uruguaiana city is dependent on where the floods are formed (high Uruguay or Ibicuí river). It was verified that there is an increase in the predictability from one day for up to three days, the further downstream the place of interest is located. After the calibration and validation of the model, the predictability analysis was performed based on 15 flood events that occurred between 19 in which the forecasts of daily time-step were compared to a reference simulation. In the evaluation the Nash-Sutcliffe efficiency Efficiency coefficient (NSE) was used. For the present research we selected municipalities that will be initially served by the CPRM Geological Survey of Brazil warning system in the Uruguay Riverriver: Garruchos, Itaqui, Porto Lucena, São Borja and Uruguaiana. The objective of this study was to investigate the predictability of critical events at points of interest in the Uruguay River river basin, that is, to evaluate how early it is possible to estimate the peak flow in some sites susceptible to flooding in the basin. The present study is a research study on this type of system, applied in the Uruguay River Basin (RS, SC, Argentina and Uruguay). The short- and medium-range flow forecasting techniques using large-scale hydrological models have several direct applications in the management of natural disasters through warning systems. Therefore, we believe that the existence of water bodies and the availability of aquatic preys play important roles in the habitat suitability for L. These observations suggest that the importance of aquatic preys is higher than previously reported in the literature. Using video recordings made in captivity, we observed that snakes were able to detect, subdue and ingest efficiently the sympatric fish Cheirodon interruptus. In the present study, we present information on the ability of L. In general, the available information suggests that the presence of tadpoles and fishes in the digestive tract of dissected snakes are the result of incidental ingestion. jaegeri is associated to humid or flooded habits, however the importance of aquatic preys in their diet has not received much attention. The available information indicates that L. Despite the wide geographical distribution of Liophis jaegeri, studies concerning its general biology and feeding behavior are very scarce. The needs related to feeding behavior drives the way species use their habitats. Dietary composition is an essential component in niche dimension and interferes in the community structuring process.
