Introduction
My general interest is freshwater environments. Particularly planktonic organisms as microcrustaceans, rotiferans and fitoplankton. We are interested also in the anthropogenic impact in the Amazon freshwater environments and ways to protect them.

A new genus is proposed to accommodate a new hyporheic species of Parastenocarididae found in the northern portion of the Espinhaço mountain range (Minas Gerais, Brazil), in the Jequitinhonha Hydrographic basin. The new genus is included within the Fontinalicaridinae due to the presence of a long male and female pereopod five, the distal rim of whi...

• An undescribed diaptomid copepod probably belonging to a new Mastigodiaptomus species has been discovered and was very abundant in El Junco Lake (San Cristóbal Island, Ecuador) from 1966 until 2004. The species was not found in samples from 2007, 2008 or 2018. • The loss of this key species from the lake coincides with the illegal introduction of...
