“No biochar benefit for temperate zone crop yields” says new report with CESAM contribution

26/04/2017

For years, biochar has been promoted as a soil additive to increase crop yields. A new study casts doubt on that view, finding that biochar only improves crop growth in the tropics, with no yield benefit at all in the temperate zone.


The team of researchers, including from CESAM, gathered data from more than 1,000 empirical observations conducted around the world, each measuring the effect of biochar on crop yield. Then, they used meta-analysis, an advanced statistical technique that analyses many studies at the same time, to test whether the beneficial effect of biochar addition depends on geography.
The report has been published, open access, in Environmental Research Letters.

Mónica Amorim, Principal Researcher at DBio/CESAM, published in Natures’ Scientific Reports

26/04/2017

Mónica Amorim, Principal Researcher at DBio/CESAM, published in Natures’ Scientific Reports “Variation-preserving normalization unveils blind spots in gene expression profiling.”

“(…) We have found that variation in gene expression is much larger than currently believed, and that it can be measured with available assays. Our results also explain, at least partially, the reproducibility problems encountered in transcriptomics studies. We expect that this improvement in detection will help efforts to realize the full potential of gene expression profiling, especially in analyses of cellular processes involving complex modulations of gene expression."

Project of Rute Costa (CESAM/DBio) - colored rings on seagulls confirm successful bird rehabilitation

28/03/2017

It is one of the long-life rehabilitation seabird monitoring projects in Portugal. Since 2013 more than 130 wounded seagulls that have entered in the Marine Mammals Rehabilitation Center (CRAM) of Quiaios or ECOMARE were tagged with colored washers, a ringing technique that allows animals to be identified by sighting without recapture. This successful project, coordinated by Rute Costa, a biologist at CESAM/DBio, has already enabled seagulls to be followed from Morocco to northern Europe.

Research study from José Alves (DBio/CESAM): Already on a diet thinking about summer?

24/03/2017

How is the transformation of coastal wetlands into rice fields in Portugal changing the diet of the birds that spend the winter there? Is this change damaging your migratory flights to northern Europe? The biologist José Alves from DBio/CESAM fears that this alterations may, in fact, affect the flight plans of these birds. This unprecedented study of wild birds was published in the latest issue of the Journal of Exeprimental Biology.

UA publishes study on photodynamic therapy in blood disinfection

23/03/2017

Two research groups from the Departments of Chemistry and Biology/CESAM of UA, which have been working for 10 years on the development of alternative strategies to antibiotics, have published an article in Future Medicinal Chemistry. As widely promoted in the media, the number of bacteria multiresistant to the current antibiotics that threatens global public health is increasing. In fact, these bacteria are currently responsible for more than 700 000 annual deaths, a number which, if nothing is done, could increase to 10 million deaths by 2050.

Irina Gorodetskaya (CESAM/DFis) - Discovering the Atmospheric Rivers of Antarctica

22/03/2017

Irina returned a few days ago from Antarctica, an immense land of a mysterious white that touch her every times she returns there. Researcher at CESAM and Department of Physics, Irina Gorodetskaya has devoted the last years of her life to the study of the climate and water cycle at the southernmost point of the planet and, in particular, the role of atmospheric rivers in Antarctic precipitation. Among the collected data, she also brought in her eyes of the beauty of a stunning land.

UA receives a visit from Researchers of the Korean Maritime Institute (KMI)

17/03/2017

Dr. Jungho NAM, Director of KMI's Sea Policy Division, South Korea, and three Researchers from his team visited the University of Aveiro, under the scope of his collaboration with the DBio & CESAM, in the context of the operationalization of the concept of services provided by marine ecosystems in maritime spatial planning.

The Marine Policy Division of this Institute conducts research in the areas of integrated coastal zone management, management and conservation of marine ecosystems, adaptation to climate changes, maritime spatial planning, among others, being responsible for the scientific based knowledge of support to the framework of the national marine and maritime policies.

The purpose of the visit was to strengthen collaboration between the two institutions, in particular in the context of the ongoing research at the UA Research and Technology Transfer Centre dedicated to Sea issues, ECOMARE.

CESAM pilot project monitors coastal erosion at Praia de Mira

14/03/2017

The University of Aveiro and the Municipality of Mira signed a cooperation protocol that will allow real-time monitoring of coastal erosion and return streams in Praia de Mira. Coordinated by CESAM, the pilot project of video-monitoring of the coastline will allow to recognize dangerous currents and the beach occupation rate and predict the erosion of the dunes.

Named as Sea Floor Topography Ranging Technique (SeaRangTech), the project includes a prototype of relatively inexpensive coastal video monitoring, when compared to commercial solutions, fully assembled at UA. This system, as explained by Paulo Baptista, coordinator of SeaRangTech and Researcher at CESAM, "aims to obtain data on the beach morphology and hydrodynamics of the wave zone, with high temporal resolution, through the acquisition of information almost continuously in time, in a beach domain with several hundred meters in length."
