Sustainable fishing in national TV (RTP2) show 'Sociedade Civil'

12/09/13
Ana Marçalo, from CESAM and DBio participated in the tv programme Sociedade Civil, on September 11, under the theme 'sustainable fishing'. In this show the Biologist presented the Good Practice Handbooks for the several Portuguese fishing methods, published under the scope of the project Life+ MARPRO - Protected Marine Species Conservation in Portugal.

Jan Keizer is the researcher of the month

10/09/13
Jan Keizer has mainly been working on hydrology and soil erosion (sensu latu), with a special focus on post-fire erosion. His research team, recently coined as “earth surface processes team” (www.cesam.ua.pt/teamsite), currently comprises 24 people.

Biological Carbon can be an ally to farmers in fighting climate change

09/09/13 
Research in CESAM, conducted in cooperation with the Bairrada wine Station shows that the biological carbon (biochar) can be an important ally to help the agricultural sector to address the adverse effects of climate change. This work was highlighted in the RTP program 'Bom Dia Portugal' of August 30, 2013.

Smoke from forest fires has carcinogenic particles

09/09/13
The smoke from forest fires is highly dangerous to public health. The alert from CESAM refers the dangers arising from the mix of gases and particles emitted by fires. The latter, ultrathin in their nature, have a enormous capacity to penetrate into the alveoli carrying out carcinogenic compounds, such as polycyclic aromatic hydrocarbons. The study, led by researcher Célia Alves, also concludes that, in addition to the human health damage, forest fires smoke contributes significantly to climate change.

Researcher of DBIO and CESAM integrates an European project on nanotechnology

09/09/13
Mónica Amorim, researcher at the Department of Biology and CESAM, in the area of ​​ nanomaterials toxicology, is the principal investigator of the Portuguese team of an European Project recently approved under the 7th Framework Programme (FP7).
The project "Sustainable SUN-Nanotechnologies," will begin later this year, in the area of nanotechnology, and has an overall budget of about eleven million. Coordinated by the University ca 'Foscari Venice, Italy, it is a "Large-scale Integrating Collaborative Project" and involves 35 partners from 16 European countries.

Researchers from University of Aveiro and CESAM describe findings in environmental research

Published in Life Science Weekly, August 20th, 2013

According to news originating from Aveiro, Portugal, changes in the transcription of selected genes in fish can be used as indicators of the sublethal impact of metals. In this study, head kidney cells of Sparus aurata (Gilthead sea bream) were exposed to copper in vitro to evaluate steroidogenic andimmune functions by measuring changes in gene transcription of steroidogenic acute regulatory protein (StAR) and in cytokines, respectively.
Paper: Teles M., Castillo J., Pacheco M., Santos M.A., Tort L. (2013) IN VITRO EXPOSURE TO COPPER INDUCED CHANGES IN IMMUNE AND STEROIDOGENIC GENE EXPRESSION IN SPARUS AURATA HEAD KIDNEY CELLS. Fresenius Environmental Bulletin, 22(2), 357-361.

Sea Life KC Aquarium joining efforts to end cyanide fishing

02/08/13
The Sea Life Kansas City Aquarium is joining a new effort to end a poisonous and destructive form of fishing called cyanide fishing. Any new fish headed to 49 Sea Life Aquariums across the world will now be tested for cyanide poisoning at Portugal's University of Aveiro.

CESAM aims to reduce soil erosion after forest fires

01/08/13
The substantial reduction of the erosion level of forest soils after the occurrence of a fire is the primary goal of mulching, a technique that is being studied in Portugal for the first time by a research team of the University of Aveiro.
The innovative method that the UA, through CESAM researchers, wants to introduce in Portugal, is the distribution of a layer of crushed forest residues (mulch) in the soils consumed by fire. Initially mulch reduces soil loss and subsequently, through its own decomposition, is incorporated in the forest ecosystem.

CESAM researchers aid to end illegal fishing with cyanide

29/07/13
Cyanide fishing is a method employed to capture marine fish alive on coral reefs. This are shipped to markets in Southeast Asia for human consumption, as well as to supply the marine aquarium trade worldwide.
CESAM researchers have now developed a methodology to indicate if live reef fish are collected using cyanide. This is a strategy that may discourage importing companies from dealing with unreliable suppliers and shift the legal pressure from impoverished fishermen to those truly profiting from this illegal and destructive activity.
