Lakes are excellent sensors of environmental change, including climate change. Chironomids (Insecta, Diptera) and ostracods (Crustacea) are among the most useful biological indicators for paleoenvironmental reconstruction found in lake sediments, due to their sensitiveness to environmental variables. However, the use…

Inventários faunísticos são fundamentais para o conhecimento da biodiversida- de e, conseqüentemente, para o planejamento e tomada de decisões sobre estratégias de conser- vação. Para conhecer a diversidade e composição dos répteis Squamata, assim como a distribuição das espécies por…

A proposta deste trabalho é utilizar técnicas de mineração de dados (data mining), também conhecida como processo de descoberta de conhecimento em bases de dados (Knowledge Discovery in Databases, KDD), para encontrar padrões em bases de dados relacionadas com a…
