(Universidade Federal de Santa Maria, 2011-02-23)
This study aims to contribute to the scarce data on the Scarabaeinae fauna of the Rio Grande do Sul, Brazil. Twenty-four samplings were made with pitfall traps baited with human excrement, rotting meat and fermented banana ...
Diversidade e distribuição espacial de comunidades de macroinvertebrados aquáticos em arrozais irrigados de duas regiões geomorfológicas no Sul do Brasil
(Universidade Federal de Santa Maria, 2015-03-16)
Wide spatial scales of analysis in studies conducted in natural wetlands tend to present the greatest contributions to the total diversity of aquatic macroinvertebrates, because they include macrovariables such as hydrographic ...
Estruturação populacional de espécies de Drosofilídeos antófilas com diferentes graus de especialização
(Universidade Federal de Santa Maria, 2019-02-28)
Recently, the study of ecological specialization has become an important component for understanding the patterns related to the population dynamics of many species. Drosophilids associated with flowers are especially ...
