A descriptive and analytical study of four neotropical drosophilid communities

Abstract: Drosophilid communities living in four different physiographical regions of the state of Rio Grande do Sul (27°/34°S; 49.7°/57.5°W), Brazil, were analysed. Ignoring cosmopolitan species, this is about the southern limit of the majority of typically neotropical Drosophila species distribution. Numerical fluctuations of the most frequent species populations from each place were investigated in relation to climatic data and trophic‐resource availability. Of the four locations studied, Turvo is remarkable for bein… Show more

“…In relation to their geological properties, Peripheral Depression unit is characterized by a flat topography and lands of magmatic sedimentary rocks with crystalline rocks; and Atlantic Plateau is characterized by orogenic belts, a continuous range of mountains with deep valleys and channels, with several soil types including cambisols, lithic, podzolic and podzolic yellow-red and red-yellow oxisol, and rocky outcrops (Ross, 2013). (Figure 1) is found in winter in good numbers in these two GMRs, as well as in many other places of the Atlantic Rainforest biome, especially in Southern Brazil and in high altitudes (Batista, Rocha, & Klaczko, 2018;Saavedra, Callegari-Jacques, Napp, & Valente, 1995). This is an almost exclusively forest-dwelling Neotropical species belonging to the tripunctata group, subgenus Drosophila (Bächli, 2018;Hatadani et al, 2009;Vilela, 1992;Yotoko, Medeiros, Solferini, & Klaczko, 2003).…”

“…Pertence ao grupo tripunctata , que compreende mais de setenta espécies (Bächli 2007), é o mais numeroso do gênero no Brasil (Gottschalk et al 2008) e a partir do qual se acredita que tenham divergido outros grupos (Trockmorton 1975). Em algumas localidades, principalmente no Sul e durante o inverno, D. mediopunctata pode ser a mais comum entre as espécies coletadas (Saavedra et al 1995); no entanto, é muito rara nas regiões mais quentes e secas (Tidon-Sklorz et al 1994;Tidon-Sklorz e Sene 1995). A espécie tem 2n=12 cromossomos, com cinco pares de acrocêntricos e um par de pontuais .…”
