Titre
Automated video image analysis of an aquatic snail (Lymnaea stagnalis) locomotor behavior as an early warning system of pollution in the Aveiro Lagoon (Ria de Aveiro)
Résumé
Because of the increasing pressure from human activities on the environment, it is imperative to develop tools to assess their effects quickly and easily, preferably in early stages of contamination. Animal behavior has gained increasing importance as a tool for ecotoxicology, since behavioral changes can occur at exposure concentrations well below those required to cause evident adverse physiological effects. As such, the use of animal behavior as an environmental quality indicator can become a powerful tool in the fight against pollution.

This work aims to develop a video tracking system able to detect changes in the locomotor behavior caused by exposure to contaminants in a ubiquitous aquatic snail (Lymnaea stagnalis), testing this system along a longitudinal gradient of aquatic pollution in the Aveiro Lagoon (Ria de Aveiro), with special emphasis on organic contaminants and metals.

Participants

Laura
Guimarães
PhD Laura Guimarães (female) is a researcher in Environmental Toxicology. She is a biologist and PhD in Biomedical Sciences (University of Porto, 2002), with work developed in CNRS (UPR 2216, France). Her expertise is in 1) biomonitoring and integrated chemical and biological effects monitoring of aquatic systems; 2) physiology and toxicological evaluation of priority (e.g., heavy metals, PAH, organophosphates) and emerging contaminants of concern, for hazard assessment in ecological risk assessment, investigation of their mode of action and relation to temperature and salinity as natural stressors; and 3) use and development of early-warning biomarkers of exposure/effect to diagnose the health status of wild vertebrate and invertebrate populations. She is member of COST Action NEREUS and participated in 16
national (1 as coordinator) and international research projects. International projects were funded by the FP6 ERA-NET AMPERA (RAMOCS) and three bilateral cooperation protocols: ICCTI/CAPES, Brazil;
French Embassy / ICCTI, France; FCT and The British Council, UK (Petgenes). She supervised or cosupervised over 25 students, technicians and young researchers, including 4 post-doctoral fellows (1 on course), 2 PhDs (1 ending), 5 MSc students (1 on course), and internships of 7 international students. She is member of the Editorial Board of Marine Pollution (specialty section of Frontiers in Marine Science and Frontiers in Environmental Science), review editor. She has over 60 international publications (over 60% of which in SCI index journals ranked within the 1st quartile (Q1) of their areas), and over 80 communications in international and national scientific meetings.
Luís
