The Intergovernmental Panel on Climate Change (IPCC) predicts increasing air temperatures and decreasing soil moisture content, the soils being among the most affected components of terrestrial ecosystems, especially in anthropogenic-contaminated areas. Soil microorganisms are key players in terrestrial ecosystem functions and services, quickly responding to environmental stresses. MICROCLIM aims to assess how microbial populations of agricultural soils affected by the contamination derived from the Estarreja Chemical Complex may be affected under the current global warming perspective, by using changes at structural and functional level. The specific objectives are: 1) assessing structural and functional changes in microbial populations of contaminated agricultural soils induced by single climate factors (soil moisture content and air temperature and their relation to changes in soil chemical and physicochemical parameters, and 2) assessing structural and functional changes in microbial populations of contaminated agricultural soils under different climate change scenarios, simulated by climate factors combinations (soil moisture content and air temperature), and their relation to changes in soil chemical and physicochemical parameters. Climate factors ranges will be established based on the emission scenarios predicted by the IPCC by 2100. The project will rely on changes in soil microbial populations at structural (bacterial community phylogenetic composition) and functional (microbial metabolic activity) level and their relation to key soil parameters (pH, organic matter, metal(loi) availability). MICROCLIM will improve the capacity to predict the consequences of global warming in soil microbiota from anthropogenic-contaminated soils, which, in turn, will enable a better preservation and sustainability of soil ecosystem functions and services.

María Nazaret González Alcaraz
María Nazaret González Alcaraz, born in 1983, is graduated in Biology (2006) by the University of Murcia (Spain) and MSc (2012) by the Technical University of Cartagena –UPCT– (Spain). She obtainer her PhD in 2012 at the UPCT on the dynamic of nitrogen, phosphorus and metals in eutrophic wetlands affected by mine wastes. From October 2013 to June 2016 she worked as Post-doctoral researcher at the Vrije Universiteit Amsterdam –VU– (The Netherlands) on the field of soil ecotoxicology. From January 2017 she is working as Marie Curie researcher (Marie Skłodowska-Curie Individual Fellowship) at the University of Aveiro on the context of the GLOBALTOX project. Her research activities are mainly focused on the effects of natural and chemical stressors on anthropogenic-degraded terrestrial ecosystems under a global warming perspective. She is also interested on the application of soil remediation strategies and greenhouse gas emissions. She has participated in 12 research projects (2 international, 6 national and 4 regional) and 14 R&D contracts with companies/administrations. Author and co-author of 34 peer reviewed papers (16 as first author and 6 as senior; h-index=8), 17 book chapters, 52 communications to national and international conferences, and 9 invitation talks (4 international and 5 national). She has already concluded the supervision of 2 PhD students at the UPCT, 4 MSc students (1 at the UPCT and 3 at the VU) and 6 Bachelor students (5 at the UPCT and 1 at the VU). Currently she is supervising 1 PhD student at the UPCT.

Loureiro
Susana Loureiro, born in 1975, is graduated in Biology (1997) and MSc in Ecology (2000) by the University of Coimbra. She obtained her PhD in 2004 on the assessment of contaminated soils, at the University of Aveiro (UAVR). In 2017, she obtained her Habilitation in Biology (UAVR). Her research activities are mainly focused on the effect of combined stressors or chemical mixtures both in environmental or human models. She is also interested on the impact of emergent chemicals as a source of exposure to organisms and humans. Within these thematic she has succeeded on several National funding applications as PI: in 2007 the project AGROMIX, on soil mixture toxicity; 2010, CLIMAFUN on the combined effects of abiotic factors and chemicals in soils and FUTRICA on chemical flow in aquatic trophic chains. As follow-up, evolutionary concepts, chemical mixtures and pulse exposures on several generations of cladocera have been addressed in RePULSE (2012). Additionally, she has built an...
Isabel
Henriques
Isabel Henriques earned her PhD in Biology in 2006 from the University of Aveiro and is an assistant researcher at CESAM where she coordinates the thematic research line “Environmental Biology and Health” and the “Microbial and Cell Biology Lab”. Her research has been oriented to the study of the effects of contaminants (e.g. antibiotics, metals) in environmental microbial communities, using culture-dependent methodologies (including genomics and proteomics) as well as metagenomics. Her main research interests also include the ecology of antibiotic resistance and the role of mobile genetic elements in antibiotic resistance dissemination. She made important contributions to her field of research, which was published in more than 80 papers in WoS journals, 3 book chapters, and over 100 oral and/or poster presentations in both national and international congresses. She coordinated/participated in several national and transnational research projects.
