Studies of the relationships between the temporal variation of biological phenomena and environmental factors are essential to understanding the dynamics of communities. Phenology is a structuring element and, together with voltinism, is related to timing of reproductive activities. The aim of this study is to ascertain the structure and compositio...

A two-year study was conducted in a conservation area of the Ventania hill system where the Pampean grassy steppes and their headwater springs maintain conditions close to natural ones. The composition and the structure of Chironomidae (Insecta: Diptera) along two short hill pristine streams and their relationship with the physicochemical variables...
Article
Riparian areas of riverine plains develop extensive floodable areas named riverine wetlands, which are essential to the water cycle balance and ecosystem dynamics. In this study, we contrasted the hydrological and physicochemical variables of riverine wetlands of both peri-urban areas impacted by intensive farming and those of rural areas with the...

Forensic entomology is a criminalistic tool that provides relevant information about circumstances of death and time elapsed until a corpse is discovered. However, it is rarely applied in aquatic environments because knowledge is scarce and fragmented. This paper summarizes the information available and contributes to the knowledge on Chironomidae...
