Alberto_facebookOVERVIEW

Before I moved to the University of Barcelona as MSc student in 2006, I worked in the aquarium hobby industry for 6 years. I did my MSc thesis at the University of Barcelona on the effects of a forest fire on the native and introduced fish species in a Mediterranean stream in the Natural Park of Sant Llorenç del Munt i Serra de l’Obac (Catalonia, Spain). A year later I started my PhD at the University of Barcelona on the use of fish as bioindicators in ecosystem health assessment using physiological markers, bioaccumulation of metals in fish tissues and changes in the composition of freshwater fish communities in Catalonia as diagnostic tools. I finished my PhD in June 2011 and it was awarded within the best PhD dissertations of my academic course in Biology at the University of Barcelona. Between June 2011 and May 2013 I was contracted as assistant researcher at the University of Barcelona and I finally moved to Cardiff in May 2013 for two years as a Marie Curie Fellow for addressing the effects of the eutrophication by nitrates in a host-parasite system.

RESEARCH

Alberto1My research at Cardiff University was funded by a Marie Curie Fellowship (Para-Tox project: FP7-PEOPLE-2012-327941, see the figure) thanks to which I could investigate the effects of nitrate pollution on species interactions, including host-parasite relationships, in a series of long-term toxicity experiments using a range of aquatic organisms: water fleas (Daphnia magna), two crayfish species (Orconectes virilis and Pacifastacus leniusculus) and fishes (guppies, Poecilia reticulata and three-spined sticklebacks, Gasterosteus aculeatus). Experimentally induced infections revealed that guppy susceptibility to Gyrodactylus turnbulli infections increased following a 30 day nitrate pre-exposure to 50 mg/l and 250 mg/l. The highest nitrate concentration was also lethal for the fish and both nitrate levels for the parasite. Such findings, however, were not mirrored in naturally infected three-spined sticklebacks since a 50 mg/l nitrate exposure did not alter the abundance of the ectosymbionts Gyrodactylus spp. and Trichodina spp. Nonetheless, nitrate levels below 200 mg/l significantly altered the foraging behaviour of two crayfish species, which highlights the difficulties of determining safe water quality when there is such variation between taxa. Also, a microcosm experiment with Daphnia magna interacting with natural microbial communities indicated that warming and nitrate concentrations ranging from 270 to 280 mg/l affected the life-history traits of D. magna, including the filtering rate. Given the key role of D. magna in nutrient cycling, our results increase our knowledge of how nitrate pollution under climate change may affect freshwater ecosystems. This experiment also enabled us to redefine the tolerance thresholds of protists and micro-metazoans, which are used as sentinel taxa in monitoring studies of freshwater ecosystems and sewage treatment plant performance. My research into nitrate pollution now continues at the University of Barcelona, Spain, where I am co-supervising the PhD student Oriol Cano-Rocabayera on the effects of nitrates on the invasive eastern mosquitofish (Gambusia holbrooki) and how the effects observed at the individual level may translate into multitrophic impacts on the food-webs of coastal lagoons. Also, studies on invasive species are the focus of my new postdoc position at Doñana Biological Station-Spanish Research Council (CSIC), Spain.
