  • ECOLOGIA MARINHA E ESTUARINA

    The main objectives of this group are six fold:     - To understand the biophysical interactions regulating larval dispersal, recruitment pathways and connectivity of invertebrate populations in the upwelling system of the west Iberian coast. The techniques employed include multi-annual, high frequency, sampling programmes, oceanographic observations, numerical modelling and genetic markers.     - To improve the characterisation the short-term variability of primary productivity in estuarine intertidal areas, through the use of non-destructive methodologies to quantify the photosynthetic activity of benthic microalgal films. Adaptation of optical techniques based on in vivo chlorophyll fluorescence, are applied, both in laboratory and in situ, to estimate photosynthetic carbon fixation rates by microphytobenthos.     - To unravel invertebrate biodiversity in bathyal ecosystems from genetic to community levels, map their distribution at local to regional scales and link diversity, density and biomass patterns to the variability of natural drivers. Also, to investigate biological capacity of key species (eg. trophic ecology, symbiosis reproduction and dispersal) and understand their potential to support ecosystem functioning.     - To develop/test methodologies for the bioassessment of coastal systems, including the performance of indicators, namely related to the implementation of the WFD, as well as remote sensing techniques, namely acoustic coupled with ground-truth sediment and biological data, to characterize and map sedimentary habitats and benthic biotopes.      - To develop an environmental-friendly technique for disinfection of wastewater using photodynamic inactivation of microorganisms, based on porphyrine derivatives.     - To identify the relevant pathogenic bacteria in fish farms of the Ria de Aveiro and to evaluate the impact of aquaculture systems on bacterial communities of the estuarine system Ria de Aveiro. Also, to evaluate the UVR effects on heterotrophic bacterial activity and on organic matter utilization.

  • Objectivos Futuros

    To attain the defined objectives, future investigation will be developed in order to:     - Investigate the effect of weather patterns on phenology and survival of model invertebrate species. The focus will be placed on the influence of larval development environment on subsequent quality of individuals and on the response of developmental rates of egg and larvae to increases of temperature and salinity. Results will be incorporated on phenology models in order to simulate scenarios of global change. Specifically, the models will explore the effects of increasing temperature on the timing of hatching, settlement and recruitment of key crustacean species.      - Pursue a more in-depth understanding of the ecophysiological adaptations that enable the high productivity of microphytobenthos in the stressful estuarine intertidal environment, through the study of the biochemical and behavioural mechanisms that provide photoprotection against photoinhibition due to oxidative stress. Also, the application of the knowledge gained and of the methodological tools developed in previous studies on diatom-dominated microphytobenthos to other photoautotrophs of significant ecological roles in coastal systems and of recognized biological interest, including phytoplankton and zooxanthelae (endosymbiotic associations with anthozoa), will be done.     - Investigate more in-depth the biodiversity and functioning of deep-sea ecosystems by using experimental in situ approaches in order to gain information on reproduction, dispersal capabilities and recruitment processes of key species, and to understand their ability to recolonize after disturbance. Studies on the interconnectivity among ecosystems will be initiated. The research will contribute to the CoML syntheses on marine biodiversity and barcoding (funded by OBIS and BOLD respectively).     - Sustain framework actions for long term ecological research and monitoring in areas of anthropogenic and natural change. Also, develop/test methodologies for the bioassessment of coastal systems and extend the study on the role and performance of indicators of change in transitional and coastal waters to disturbance sources others than organic enrichment (dredging, hypoxia, storms). Extend the AGDS approach for habitat characterisation and mapping to shallow water transition systems, as well to the whole Portuguese coastal shelf, while incorporating double-frequency surveying and specific biotope studies. In addition, develop reach out activities to promote public awareness of biodiversity and related ecological services.     - Develop microbiological and molecular tools that can be used in the rapid detection of microbial pathogens and virulence factors in the aquatic environments and in actions of environmental bioremediation of acute chemical and biological contaminations. Samples collected in different marine environments characterized by high genetic diversity, such as estuarine water and sediments and mud volcanoes, will also be explored by metagenomic technologies directed to potential biotechnological applications.

  • Marine Microbiology and Biotechnology Lab

    Marine Microbiology and Biotechnology LabMolecular tools are used to develop strategies of biocontrol of pathogens in aquaculture systems, for source-tracing of marine products and for the analysis of genetic resources and bioactive compounds produced by marine microbes that can be used in industrial or bioremediation applications. The bioprospecting of marine invertebrates and macrophytes is also addressed, with emphasis on biomass produced under controlled conditions to secure replicability and avoid the loss of the source.Biossurfactant production by marine bacteria, particularly under oxygen limiting conditions, is being optimized by co-cultivation with inducer strains and by use of low-cost carbon sources. Biological activity of the produced biossurfactants is being tested in the perspective of their use as quorum-sensing inhibitors and environmentally agents of biofilm control.The lab also uses phage therapy and photodynamic therapy as alternative environmentally friendly methods to control fish and bivalve diseases in aquaculture. Marine Microbiology and Biotechnology Lab also make routine analysis of microbiological quality, namely to evaluate the quality of final products (e.g. fish, bivalves and water) but also during the implementation/monitorization of procedures (e.g. depuration of bivalves, HACCP programs). The Marine Microbiology and Biotechnology Lab is led by Adelaide Almeida.

  • Infraestruturas Comuns

    - Laboratory for Molecular Studies of Marine Environments (LEMAM), University of Aveiro, Portugal.The Laboratory for Molecular Studies of Marine Environments (LEMAM) was created in October 2009 by the Biology Department (DBio) and the Centre for Environmental and Marine Studies (CESAM) at the University of Aveiro as a platform for developing and reinforcing research, technology transfer and service provision. The laboratory has become an innovative component of the University in basic and applied research with a strong national and international presence in several areas including molecular microbiology, aquaculture, biotechnology and bioentrepreneurship. Currently, there are several ongoing basic and applied research projects in addition to projects with a strong focus on the development of patents and knowledge transfer to different industry sectors.The specific goals of LEMAM are to: 1) study marine ecosystems exposed to the interactive effects of anthropogenic contaminants and phenomena related to global climate change; 2) investigate gene pools of marine microbes for ecological studies and biotechnological applications; 3) develop molecular techniques to be used in the fields of marine ecology and biotechnology; 4) support knowledge transfer and multidisciplinary collaborative projects in the field of marine ecology and 5) promote innovation and stimulate entrepreneurship in the biotechnology sector.The Laboratory for Molecular Studies of Marine Environments is led by Newton Gomes.- Biological Research CollectionWebpage: http://leme.web.ua.pt/leme/cobi.htmlThe Biological Research Collection (COBI) is a repository of natural history specimens and jointly curated collections such as frozen tissues and other physical samples, e.g. DNA libraries and digital images. The collection contains specimens from coastal to deep-sea environments collected under sampling programs of several Research Projects. The specimens are being prepared in a way that ensures their utility and are accessible to all qualified users. Specimen-associated information is managed through archiving in Specify 6 and GIS databases. COBI also has a bibliographic collection of 4015 references that gives support to the biological collection.The Biological Research Collection of Marine Invertebrates (COBI) was started in 1999. The aim of the collection is to serve as a tool to assist the identification of Portuguese marine invertebrates, and to be a contribution to the national and international scientific community by providing specimens for taxonomic, genetic, biogeographic and evolutionary studies. More recently, the collection has been considerably improved in either infrastructures and the amount and diversity of biological material deposited. Presently, the collection includes 5106 registers of 972 taxa (the majority to species level) collected mainly in Portuguese waters and NE Atlantic, but also from other areas. Thirteen Phyla of invertebrate fauna are represented: Annelida, Arthropoda, Bryozoa, Cnidaria, Chordata, Echinodermata, Ectoprocta, Entoprocta, Mollusca, Nemertea, Platyhelminthes, Porifera and Sipuncula. This fauna was collected in a wide variety of habitats, from the intertidal to deep-sea environments, including submarine canyons, cold seeps, mud volcanoes, and hydrothermal vents.
