“…Drosophila mediopunctata is an almost exclusively forest dwelling species (rare or absent in Brazilian savan nah [cerrado] and caatinga; see Tidon 2006, Mata et al 2010. It has 5 pairs of acrocentric chromosomes and 1 pair of dot chromosomes that do not polytenize (Kastritsis 1966), and is highly polymorphic for chromosome inversions.…”

Unexpected long-term changes in chromosome inversion frequencies in a Neotropical Drosophila species

Several long-term studies on Drosophila chromosome inversion polymorphisms have shown that inversions can be a valuable tool to monitor rapid genetic shifts with climate change. However, so far, no study has assessed the effects of climate change in populations of Neotropical Drosophila species. After more than 2 decades, new samples were collected from the Parque Nacional do Itatiaia, Rio de Janeiro, to assess any changes in inversion frequencies and to detect possible global warming effects on the inversion polymorphism of the second chromosome of D. mediopunctata. Our results show unexpected simultaneous changes in inversion frequencies associated with climate change. Perhaps climatic variables other than temperature underlying the process caused such change, although potential genetic drift effects or demographic factors cannot be excluded. Further studies assessing population genetic structure may help clarify the changes observed.

“…Flies from the Drosophilidae family have been suggested as appropriated for the assessment of the effects of habitat fragmentation (e.g., Mata et al, 2010). Cavasini et al (2014) evaluated the Drosophilidae assemblages of Araucaria Forest fragments in Guarapuava/PR (southern of Brazil), including one studied here.…”

The Brazilian Cerrado, a vegetation mosaic considered to be a unique savannah hotspot, contains a great diversity of insects. It is uncertain how communities of insects in the Cerrado respond, at local scale, to the strong heterogeneity of the biome or to the increasing levels of anthropogenic disturbance. This study examines the relative importance of habitat heterogeneity and human disturbance for the structure of drosophilid assemblages in this biome. Our results are based on standardised monthly sampling at 25 sites (3 conserved forests, 4 disturbed forests, 8 conserved savannahs, and 10 disturbed savannahs) throughout 1 year. The assemblage compositions differed across habitats. The conserved forests had a singular drosophilid assemblage characterised by typical narrow‐ranging neotropical species. Assemblages from savannahs and disturbed forests contained more exotic species than those from conserved forests. The assemblages of disturbed forests were more similar to those of the savannahs than to those of the conserved forests. Savannah assemblages did not differ from each other; these assemblages shared a great number of both exotic and neotropical species widespread in neotropical regions. At the reserve scale, the strong natural heterogeneity of the Cerrado is the primary factor impacting the structure of drosophilid assemblages. Nevertheless, disturbance explained the differences in assemblage structure between the conserved and disturbed forests. Even low disturbance levels in forests could cause a decrease in heterogeneity and begin to impoverish these environments, leading to the biotic homogenisation of this currently rich biome.
