A BR 101 é uma rodovia de grande importância para o país e vêm sofrendo obras de duplicação para diminuir o número de congestionamentos e acidentes ao longo de sua extensão. O trecho compreendido entre o km 190,3 ao km 144,2 transpassa uma Unidade de Conservação (UC) e uma Área de Proteção Ambiental (APA), áreas onde a biodiversidade deve ser preservada, tendo seu amparo legal através de Lei 6938/81, Política Nacional do Meio Ambiente. Foram identificados onze impactos ambientais do meio biótico causados por este empreendimento e avaliados através de uma matriz de interação. Os impactos foram negativos e revelam uma situação preocupante devido aos danos permanentes causados ao ecossistema adjacente, que podem afetar as populações da fauna e da flora.
Three new species of DexosarcophagaTownsend, 1917 are described based on male specimens collected in Brazil, Dexosarcophaga sinoisp. nov., Dexosarcophaga autisferasp. nov., and Dexosarcophaga clavissp. nov. Male morphology is represented by photographs and detailed illustrations of terminalia. Dexosarcophaga carvalhoi (Lopes, 1980), Dexosarcophaga globulosaLopes, 1946, Dexosarcophaga limitata (Lopes, 1975), Dexosarcophaga paulistana (Lopes, 1982b), and Dexosarcophaga petraSantos, Pape and Mello-Patiu 2022 are recorded for the first time in Argentina. Also, Dexosarcophaga lenkoiLopes, 1968, Dexosarcophaga montana (Lopes, 1975), and Dexosarcophaga transitaTownsend, 1917 have their distribution expanded with new records. Dexosarcophaga transita is considered a senior synonym of Dexosarcophaga chaetosaBlanchard, 1939syn. nov., Dexosarcophaga itaquaDodge, 1966syn. nov., and Dexosarcophaga lopesiDodge, 1968syn. nov. With the addition of the new species and the new synonymies proposed, Dexosarcophaga now contains 58 species, of which 10 are recorded in Argentina and 35 in Brazil.
Sarcophagidae is a family of Diptera with medical-veterinary importance, which have species with sarcosaprophagous, necrophagous or causing-myiasis larvae, among others. The Brazilian state of Rio de Janeiro has 92 municipalities, but only 26 have sarcophagid records and the municipality of Rio das Ostras is one of the least registered, with only nine species recorded. This works aimed to increase the knowledge of flesh fly diversity in a conservation unit of this municipality, the “Área de Relevante Interesse Ecológico de Itapebussus”. The study was conducted in restinga and semideciduous forest. We used modified Van Someren-Rydon traps baited with decayed fish, and the samples were taken in dry and rainy seasons. A total of 446 male sarcophagines of 18 species of the genera Oxysarcodexia, Peckia, Ravinia, Sarcofahrtiopsis, and Titanogrypa were collected. We found 13 new records for the sampled municipality. The forest presented higher richness than the restinga and the most abundant species was Oxysarcodexia amorosa (Schiner). Diversity and equitability showed similar values in the two areas (H'f=2.193, H'r=2.027, J'f=0.7908 and J'r=0.7682) and the cluster analysis suggest high similarity. PERMANOVA did not present significant results for any source of variation. The presence of synanthropic and asynanthropic species in the fragment demonstrates that it is already a somewhat human-impacted environment. Marked increase in the number of sarcophagid records obtained in this small sample in the studied municipality (from nine to 22 species) shows the importance of taxonomic surveys in poorly studied areas.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
