How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I am a PhD student at the Federal University of Santa Catarina, Brazil, and a researcher at the Instituto de Conservación de Ballenas, Argentina. My PhD research aims to estimate population parameters for the Southern right whales. In my Master degree I studied the effects of the habitat disturbance on the distribution of a small resident population of bottlenose dolphin in Southern Brazil. In my undergraduate degree I worked with aquatic ecotoxicology and environmental contamination.
Whales contribute to marine ecosystem functioning, and they may play a role in mitigating climate change and supporting the Antarctic krill (Euphausia superba) population, a keystone prey species that sustains the entire Southern Ocean (SO) ecosystem. By analyzing a five-decade (1971–2017) data series of individual southern right whales (SRWs; Euba...
A small population of coastal bottlenose dolphins (Tursiops truncatus gephyreus) inhabits the inland waters of Laguna, southern Brazil. A subset of this population interacts with artisanal fishermen. This specialized foraging tactic structures dolphin society into ‘cooperatives’ (participants of the interaction) and ‘non‐cooperatives’ (non‐particip...
This work aimed to study in the freshwater gastropod Planorbarius corneus the effects of acute (2 days) and subchronic (14 days) exposures to an environmental concentration of the organophosphate azinphos-methyl on different reproductive parameters, offspring survival and B-esterase activities in gonads and in the whole organism soft tissue. The ac...
Chlorpyrifos is an organophosphate insecticide widely used in a variety of food crops in Argentina and other countries. In a previous work, we have reported that subchronic exposure (14 days) to an environmental concentration of chlorpyrifos (5 μg L- 1 ) caused severe effects on reproduction of the freshwater hermaphrodite gastropod Planorbarius co...
Chlorpyrifos is an organophosphate insecticide used for pest control on a number of food crops in many parts of the world. In recent years, there has been an important decrease in the number of organisms of Planorbarius corneus. Since the presence of pesticides in the water can be one of the reasons for this decrease, it is very important to study...
