The transposition of the Piumhi River caused the introduction of many aquatic species in the São Francisco basin. Species previously restricted to the Upper Paraná basin, such as Leporinus octofasciatus and Parodon nasus, are now present in the São Francisco basin. However, the morphological identification of the invaders is not always possible. This becomes evident in the cases where the invading species are cryptic of native species, and when the newly introduced species already has a resident population. Therefore, the present work had the objective of characterizing and mapping the dispersion of a few invader species in the São Francisco basin using cytogenetic markers. Populations of Astyanax altiparanae, A. fasciatus and A. lacustris were analyzed. Besides a large chromosomal similarity, chromosome polymorphism where the two species were in sympatry was evidenced between the cryptic species A. altiparanae and A. lacustris, suggesting the occurrence of hybridization. On the other hand, differentiations regarding quantity and distribution of C-bands, AS-51 satellite DNA sites, Ag-NOR sites, and 18S and 5S rDNA sites, were seen between the A. fasciatus populations from the Upper Paraná and São Francisco basins. These chromosomal markers differentiated species from the Upper Paraná basin that invaded the São Francisco basin. No specimens with intermediary chromosomal characteristics between the native and introduced populations were found. This fact suggests that the Upper Paraná populations may constitute a distinct species.

System reuse is a Software Engineering technique that proposes the construction of software systems from existing artifacts. One way to develop systems reusing code and project in a specific domain is using application generators. These generators automate part of the development process, reduce costs, allow the increase of the development team productivity, enhance systems quality and minimize error insertion arising from the implementation phase. The GawCRe (Web based Application Generator to the Rehabilitation Clinic domain) was developed using the software product lines technique based in the SiGCli (Rehabilitation Clinics Management System) pattern language. This generator went through some maintenance in order to allow the MySQL RDBMS usage, as well as to carry out version control of the generated applications and increase its domain to others related to it. Currently, there is interest in the usage of Service Oriented Architectures (SOA) to support the construction of software applications that use services available in a network, as the Web. These services are an implementation of well-defined business functionality that can be used by clients of different applications. The reutilization of available services in the construction of new Web systems is increasing, reducing the rework and facilitating the maintenance of these systems. This master's thesis presents an approach to modify application generators in a way that its domain is increased by the use of Web Services provided by Service Oriented Architecture. This architecture eases systems' adaptation, making them dynamic, as their services can be swapped in runtime. This allows future maintenances to be eased, because modifications in the services are reflected in the applications without user intervention. The GAwCRe undergone for maintenance to support the use of Web Services provided by a SOA, thereby, broadening its domain. A case study was conducted using the GAwCRe and some Web Services attempt to evaluate the combined use of SOA and Application Generators.
