Cocktails of pesticides are harming for soils health

14/04/2014
Cocktails of pesticides, used in agriculture to fight pests, are causing harmful effects on organisms that regenerate the terrestrial ecosystem and, therefore, are undermining the health of Portuguese soils. This is the main conclusion drawn by team of CESAM biologists that examined the effects of mixtures of pesticides, used on a large scale throughout Europe, in organisms that are damaged by the chemicals action. Without them, and consequently without the crucial role they have in organic matter decomposition and redistribution of nutrients, agricultural soils can not stay healthy.

CESAM team studies the mitigation of soil erosion that occurs after forest fires

UA in the largest European project on soil degradation in Europe

Nobody knows what  is the health state of Portuguese soils. For certain, the variety and intensity of threats are enormous. Among the culprits, desertification and land impermeabilization  appear to head a long list of phenomena. To assess for the first time the state of the national soil, identifying and studying phenomena that affect them and develop innovative solutions to prevent, in the long term, the country's south region - mainly - to become an arid desert, a team of researchers from the UA have rolled up their sleeves. The mission of Portuguese scientists is part of RECARE project, the EU largest project aiming for the prevention and remediation of soil degradation in Europe, is officially launched on April 1 and has a multidisciplinary team of researchers from 27 European organizations.

Project RECARE joins the local population and agents in the initiative "Planting Caramulo"

28/03/14
On March 22, 2014, CESAM researchers participated in the 'Planting Caramulo' initiative, sponsored by the city of Viseu in conjunction with other local and regional entities.
Agents and local communities joined forces in a voluntary movement to plant 10,000 trees (mountain oak and birch) to restore some of the public lands that were affected by large forest fires that consumed more than 9,000 acres of forest in the Caramulo mountain range during the summer of 2013. These fires triggered not only the loss of human lives but also large environmental and socioeconomic impacts. In the joint area of St. John 's and Mount Mosteirinho' Parishes, one of the areas of study of the RECARE project around 600 trees were planted with great enthusiasm despite adverse weather conditions.
The initiative was a huge success, with more than 1,000 volunteers and local organizations, schools and citizens associations, thus  demonstrating awareness of the local actors to direct and indirect impacts of forest fires and the need to implement solutions to rehabilitate burned areas and mitigate soil degradation.

Researchers from UA propose new solution to inactivation of drug resistant bacteria in sewage

25/03/2014
A multidisciplinary team from the University of Aveiro, including CESAM members, has been working on new applications of scientific methods used in other areas in order to seek a solution to the resistance of bacterial strains to various antibiotics. 
One such method, named photodynamic therapy has been tested in the treatment of hospital sewerage, where multidrug-resistant bacteria are frequently found, and according to studies conducted, so far it has shown to be much more effective than other conventional approaches.

Project ADAPT-MED

17/03/14
ADAPT-MED is a European research project which accompanies local decision-makers in elaborating adaptation strategies to climate and global change in a context of uncertainty, coastal risks, endangerment of ecosystems, as well as urban and water management issues. Partners from France (ACTeon and BRGM), Greece (University of Athens) and Portugal (ISCTE-Instituto Universitário de Lisboa, University of Aveiro-CESAM) will work in three distinct research sites on how knowledge affects perceptions on climate change and how perceptions affect decision-making at all levels (economic, social, environmental policies) when dealing with climate change. It is innovative in the sense that it joins psychological, socio-economic, political science and scientific (geographic, geomorphologic and marine biologic) skills in one project. The project was launched in December 2013 and will last 24 months.

CESAM researchers publish about animals with chloroplasts in the journal of the Royal Society

11/03/14
A team of researchers of CESAM published a paper in Philosophical Transactions of the Royal Society B, a journal of high scientific impact, concerning the research on 'kleptoplasts', the name given to chloroplasts in the tissues of a non-photosynthetic host.
The article updates the state-of-the-art on kleptoplast photophysiology, focusing on the comparative analysis of the responses to light of the chloroplasts when in their original, macroalgal cells, and when sequestered in animal cells and functioning as kleptoplasts.
Abstract of the article here.

Where's the squirrel?

06/03/14
The little red squirrel had settled all over the country for many centuries. The disappearance of forests and woods where it used to roam have led to its scarcity. A while back there were news of its return, but where does it walk now? That's what a study of CESAM/UA intends to find out.
Rita Gomes Rocha created the red squirrel project in Portugal with the aim to better understand this species, their behavior patterns and identify factors that may influence its expansion. The data will be the subject of study within her postdoctoral work at UA.

UA biologists discover the wild world of the planet

28/02/2014
Biology and genetics, management and conservation of animal populations, study of ecosystems and biodiversity are some of the areas that the Wildlife Unit of UA/CESAM embraced within and outside the country. Coordinated by the biologist Carlos Fonseca, the Unit has fifty researchers, divided between the national territory, several European countries, Brazil, Bolivia, Cape Verde and Mozambique, contributing all to a harmonious relationship between humankind and the environment.

Research of CESAM developed to help consumers

21/02/2014
A team of biologists of CESAM developed a novel traceability test that, through a microbiological examination of fish mucus, determine the provenance of the product. The test is ready to be used by any saltwater fish farming.
