Introduction
I focus on the impact of land uses on streams, using biological communities as indicators and ecotoxicology as an assessment tool. My project evaluates the role of riparian ecosystems in mitigating runoff from horticultural crops under conventional and agroecological modalities.

This study aimed to determine the impact of horticultural land use on the taxonomic composition and the composition of functional feeding groups of freshwater macroinvertebrate assemblages in lowland streams. Three streams running through intensively cultivated plots were compared to three less impacted streams, two of which run through a UNESCO Bi...

Pyrethroids are among the most widely applied insecticides worldwide and cypermethrin is the pyrethroid most used in Argentina. Pesticides used in crops can reach adjacent watercourses through runoff and may lead to non-target fauna receiving toxic pulse exposures. The aim of this study was to determine the effects of cypermethrin pulse exposures o...

The agrochemicals used on crops can reach watercourses, affecting water quality and biologic communities. The aim of this research was to study the effects of horticulture on the water quality and invertebrate assemblages of adjacent streams in Buenos Aires province, Argentina. Four streams draining horticultural basins were compared with another f...
Article
The use of agrochemicals in Argentina has increased over the last decades and may represent an environmentalrisk for adjacent water bodies. In this work we study the invertebrate assemblages in nine streams sampled at 11sites with different land use on the adjacent plots in the years 2011–2014. Four sites were located inside a biosphere reserve, 4...
Thesis
El Cinturón Hortícola Platense (CHP) se ubica en el noreste de la Provincia de Buenos Aires, presenta una superficie de 3.709 hectáreas, una producción de 78.000 toneladas/año y abastece de verduras a 14 millones de personas; se considera una de las regiones productivas más importante del país. El modelo de producción hortícola responde a un modelo...

Chlorella vulgaris (Chlorellales) es un alga verde, unicelular, ampliamente usada en bioensayos y como alimento para organismos pastoreadores debido a su elevada palatabilidad y rápido crecimiento. El objetivo del trabajo fue determinar las condiciones óptimas en las que se observa el pico de la fase exponencial de C. vulgaris, en base a tres facto...
