A group of scientists from UA are trying to use biochar for the first time to combat soil erosion in a vineyard in Amoreira Gandara, Anadia. This unprecedented work intends to identify how this type of biomass-produced coal can improve water infiltration of the soil in vineyards.
This research has been conducted by the 'Earth Surface Processes (ESP) team' (Earth Surface Process research team), a CESAM researchers team led by Jacob Keizer. This work is part of the project "Mediterranean Agricultural Soils Conservation under Global Change (MASCC)", funded by FCT under the ARIMNET program, with João Pedro Nunes as Main Researcher from the Portuguese team.
With the incorporation of biochar in the soil, ESP team expects a reduction in the water flow by 10 to 50 percent and a reduction of 20 to 60 percent in the soil erosion. This percentages, according to the researchers, "mean that more water will be stored in the soil after rainfall, a fact that can benefit both the vineyard and the quality of watercourses".
The study of the use of biochar in agricultural production in Portugal is now taking the first steps through an interdisciplinary team of researchers from DAO, DBio and CESAM.

This study used the mussel Mytilus galloprovincialis to investigate connectivity between the Berlengas and Arrábida MPAs in Portugal, both of which are part of the Natura 2000 network of protected sites in Europe. The chemistry of mussel shells was used to trace the dispersal routes for larval mussels, demonstrating that the Arrábida MPA is an important source population in the area. Results from this study support the measures in the 2005 management plan for the MPA, which prohibited trawling, dredging and bivalve harvesting to preserve its role as a nursery for many marine species. Direct measures of habitat connectivity can be a powerful tool to inform policymakers on the conservation and management of networks of protected areas in coastal marine ecosystems.

Competition of SME Instrument Program received nearly 2000 applications from 40 countries.
After being awarded by the seal of excellence of the European Commission, under Horizon 2020 Program, the spin-off DNA TRUSTAG, born at the University of Aveiro (UA), was funded with 50,000 euros in Phase 1 of the SME Instrument Competition within another area of the same program. This spin-off was one of 12 Portuguese funded from almost 2,000 candidates from 40 countries.
The European Commission's seal of excellence have already certificated the innovative nature and the commercialization potential of this technology developed in the Department of Biology and CESAM, with a registered patent with the support from the Technology Transfer Unit of UA (UATEC), and licensed by the DNA TRUSTAG company. Now it is funded through the same program of the Commission, the SME Instrument, dedicated to supporting SMEs, and after an application of the business plan to the security area of this program.
The technology that enables the production of unique DNA codes presented by this spin-off was one of the applications with best score in the context of a highly competitive competition. Newton Gomes and Francisco Coelho form the hands-on team of this spin-off.
Research of Estuarine and Coastal Modeling Center from Department of Physics
Built to accommodate waste from the iron mines of the Mariana region, in the Brazilian state of Minas Gerais, the Fundão barrage rupture in 2015 caused one of the biggest environmental disasters in Brazil. The mud released by the disaster struck the Rio Doce and, and through this the Atlantic, with consequences that can only now be quantified. An important help to realize the real impact of the tragedy reached from the University of Aveiro, by satellite images analysis and by the development of a numerical model that simulates the spread of fluvial water in the Atlantic.
This work, one of the first to be held on the tragedy of Rio Doce, involved researchers Renato Mendes and João Miguel Dias from Estuarine and Coastal Modeling Center from Department of Physics / CESAM in partnership with researchers Martin Marta-Almeida (former UA student and researcher), Fabiola Amorim from Federal University of Espirito Santo (also a former UA student and researcher) and Mauro Cirano from the Federal University of Rio de Janeiro.
Since its publication in the Marine Pollution Bulletin, the most prestigious magazine on marine pollution, this joint work between Portuguese and Brazilian researchers was several weeks among the most read articles published by UA and was the most widely read from CESAM.

Since the beginning of the year more than 160 thousand hectares of forest were consumed by fires, and the burned area more than doubled compared to 2015. After fighting the fires, with the temperature drop, it’s time to look at what's left. This was one of the main issues highlighted in the Click emission of 15th of October, the UA radio program transmitted on Saturdays after the 3pm news on Antena 1. In this edition, we hear the opinion of Jacob Keiser and Nelson Abrantes, experts of DAO and CESAM, on the impact of fires on land, water systems, biodiversity and ways to prevent erosion.

Dolphins in Portuguese coast have the highest levels of mercury in the body when compared to populations in the rest of the European coast. The amount of this highly toxic heavy metal, whose values present in national populations of dolphins were investigated by a team of UA biologists, is only surpassed by the same species that live on the shores of the Mediterranean and Adriatic seas. This research gives an alert and says that we may be facing a "potential problem associated with mercury in the marine ecosystem in Portugal."
Researchers point out that the main mercury and other chemical pollutants inlet by dolphins occurs by swallowing. Sylvia Monteiro, biologist at DBio/CESAM, points out that "some of the main prey of these dolphins are important commercial species, representing food often ingested by humans."
Silvia Monteiro recalls that "there are already several studies showing that exposure to heavy metals affects the development and growth in neurological processes and reproductive success, and may cause mutagenic changes, immunosuppression and liver and kidney damage. "

The work "Scientific study on water erosion following forest fires", carried out by the CESAM Laboratory of Eco-Hydrology, was recently published in the Informative Sheet of the Rural Network journal - No. 70 - September 2016 - Special Forest. This is a special edition dedicated to good forest management practices.
The team of the Eco-HydrologyLaboratory is presently conducting a scientific study, under field conditions, to test the effectiveness of the application of a layer of forest residues from the cutting of eucalyptus on recently burned soil as a protection action against water erosion.
Management of sustainable forest is the aim of the most recent international partnership led by UA biologists
FOREST-IN: INovative and Educational INformation for the Sustainable FOREST Management by Smallholders is the new European project recently approved for DBIO, UA. The Community funding, which exceeds 320,000 euros, was obtained by the Erasmus + program, the European Commission financial instrument of Education. In this case, the forest education of all actors in the forestry universe, from small forest owners and technicians to large makers, will be the main focus of this mission that will last for three years.
FOREST-IN project emerged from the need to create an agreement platform to unite the various forestry agents from Portugal, Spain and France, which usually face similar forest problems. In these countries, the predominance of private forest property, of small dimensions and mostly under the non-technical proprietary management, lead to the proliferation of practices that sometimes threaten the integrity and forest productivity and affect the ecosystem services as a whole, being urgent to share good practices and to promote forestry education.
UA researchers present conclusions of the project about sapal evolution in Ria
What changes have occurred in the marshes of Baixo Vouga Lagunar (including juncal and caniçal) in the last decade? What is the importance of the marshes as a carbon sink? Will the carbon storage in the marshes of Baixo Vouga Lagunar be affected by the rise in sea level? These are the fundamental questions to which the project "MARSH-C-LEVEL - Role of the marshes of Baixo Vouga Lagunar in storing carbon as a service of the ecosystem: Effects of sea level rise" intends to respond. The conclusions will be presented at the final seminar of the project, on September 29, at 2:30 p.m., in the Municipal Library of Estarreja.
