Understand proliferation patterns of invasive species and their relation to ecosystem transformations is of great importance faced to global conservation goals, unfortunately research efforts are not well addressed to evaluate the potential risks of invasive species in altered ecosystems. In this dissertation, will be tested a recently sampling method developed for estimated the proliferation of non-native fishes in Neotropical reservoirs, known as Rapid Assessment Protocol (RAP) that use Citizen Science data for access to biological information. With the records obtain, will be predict the invasion area of the introduced fishes in the Upper Paraguay River basin, using the Site-Occupancy modeling as alternative to consensus Species Distribution Modeling (SDM). The models will be predicted by the fragmentation, loss of connectivity among predictors like (transparency and temperature of water). The models will be ranked using the Akaike’s Information Criterion (AIC) and will be selected those showing better performance for will mapping the probability of occupancy and detection calculated for each one introduced fish species in the basin. Finally the distribution will be tested with the respective field validations. The objective of the project is generate models can predict the areas of greatest risk invasion as tool for these introduced species management.
