Pedro Echeveste, PhD.

Dr. Pedro Echeveste (Spain, 1981) is a postdoctoral researcher at the Pontificia Universidad Católica de Chile. Within the project “Trace metals role in marine phytoplankton composition and distribution in the Humboldt Current System (HCS)” (Fondecyt #3150507), his research in IMO focuses on analyzing the role of trace metals on cultured phytoplankton species and natural communities of the HCS, through changes in the growth, physiology, biochemistry, molecular activity and species composition at required/excess levels of metals; and additionally, the influence of phytoplankton community composition on metal bioavailability and seawater physicochemical characteristics. This research is supervised by the IMO associate researcher Dr. Peter von Dassow

Dr. Echeveste's postdoctoral experience started back in 2012 at the Universidade Federal de São Carlos (Brazil). Within the project “Effects of free Cu2+ and Cd2+ ions on the physiology of freshwater phytoplankton (CNPq #401214/2012-5)", he analyzed the biochemical and physiological effects of copper and cadmium on freshwater phytoplankton, under the supervision of prof. Lombardi.

Back in 2011 Dr. Echeveste achieved his doctoral degree in Biology. His PhD, entitled “Thresholds and points of no return for oceanic phytoplankton: effects of pollution on phytoplankton communities”, was held at the Instituto Mediterráneo de Estudios Avanzados (Spain), under the supervision of prof. Agustí. This PhD was focused on the effects of persistent organic pollutants and trace metals to cultured and natural communities of phytoplankton of the Mediterranean and Black Seas and the Atlantic, Arctic and Southern Oceans.

Previously, Dr. Echeveste obtained his Bachelors degree in Biology from the Universidad de Navarra (Spain) in 2003, and a Master degree in Climate Risks and Environmental Impact from the Instituto Nacional de Meteorología in Madrid (Spain) in 2004.

Dr. Echeveste's interests include:

  • The role of microbial communities in the anthropogenically-impacted biogeochemical cycles of aquatic ecosystems and how these communities adapt to environmental perturbations.
  • The impact of both legacy and new emerging pollutants to microorganisms and the role of these communities on the fate of contaminants.
  • The trophic transfer of these pollutants through the water column, both through grazing processes (bottom-up regulations and biomagnification/bioaccumulation processes), or through cell death/sedimentation of microorganisms to lower compartments of the water column, such as the deep seawater community.
  • The effects of Global Change on the fitness of these communities and the reactivity of the different pollutants occurring in fresh and seawater.
  • The role of microorganisms in altering water-masses' conditions, such as eutrophication processes, harmful algal blooms occurrence or the formation of oxygen minimum zones (OMZ) and its coupling to low pH conditions (high pCO2).
