CSIC scientists identify a new fault in the Alboran Sea

Wed, 25/07/2018 - 10:30
23 July 2018

An international group of scientists led by the Spanish National Research Counci (CSIC) has identified a new fault in the Alboran Sea. The fracture produces little deformation in the seabed, although there are "relatively high magnitude earthquakes", such as the magnitude 6.3 on the Richter scale that affected the city of Melilla and several areas of Andalusia on January 25th on 2016. The results of this research, published in the journal Tectonics, allow establishing potential geological risks in the Alboran Sea.

New clues to analyse gene expression through epigenetics: the first intron as a key gene region

17 July 2018

Epigenetics, the study of heritable changes in gene expression that don’t involve changes in the DNA sequence, is an extraordinarily active research field in biology nowadays. Epigenetic modifications integrate environmental and genetic information to give a certain phenotype (the set of characteristics showed by an individual) and can be transmitted from generation to generation, making it possible for characters acquired by environmental influence to be inherited and passed on to the descendants.

Omics in Ecology: main topic in the VI Ramon Margalef Summer Colloquia

Wed, 11/07/2018 - 10:42
10 July 2018

From 8th to 13th of July takes place the sixth edition of the "Ramon Margalef Summer Colloquia", organized by the Institute of Marine Sciences (ICM-CSIC) and the Catalan Association of Oceanographers and Oceanographers (ACOIO). Since its first edition in 2013, it gathers each summer young researchers and experts to exchange ideas on the advances in ecological research.

The deep ocean microbiome is the mirror of the surface ocean

Mon, 09/07/2018 - 12:35
3 July 2018

Most of sea life is on the illuminated surface (first 200 meters), while the deep ocean (up to 4,000 meters deep) is almost empty. A study led by the Institute of Marine Science (ICM-CSIC) has found that, despite the differences between these regions, the microbial biodiversity of both is intimately connected. The results of the study, which are published in the journal Proceedings of the National Academy of Science (PNAS), help to better understand the functioning of the planet and the great dispersal capacity of microorganisms.

Polar oceans, not tropical waters, are species-formation hot spots for marine fishes

Mon, 09/07/2018 - 11:43
5 July 2018

Tropical oceans teem with the dazzle and flash of colorful reef fishes and contain far more species than the cold ocean waters found at high latitudes. This well-known “latitudinal diversity gradient” is one of the most famous patterns in biology, and scientists have puzzled over its causes for more than 200 years.

SIBECOL, the first scientific society of experts on ecology of the Iberian Peninsula

Mon, 09/07/2018 - 11:25
2 July 2018

Today, the new Iberian Society of Ecology (SIBECOL) has been constituted, starting with more than two thousand professionals from Spain and Portugal from all areas of ecology in terrestial and water ecosystems. The signature was made this afternoon at the Institut de Ciències de Mar de Barcelona (ICM-CSIC), which host SIBECOL.

New evidence of contaminants in deep sediments of Antarctica

Tue, 26/06/2018 - 17:12
14 June 2018

Industrial activity generates harmful substances that can reach the most remote places on the planet, transported by winds and ocean currents. A new study conducted by the Institute of Marine Sciences (ICM) and the Institute of Environmental Diagnosis and Studies of Water (IDAEA), both centres of CSIC, has detected cellular toxicity produced by anthropogenic-compounds in Antarctica seabed. Samples of Antarctic sediments come from several stations along more than 4,000 kilometers from the Weddell Sea and off the coast of the Antarctic Peninsula.

Towards the sustainability of fishing resources: A historical agreement to co-manage Girona's fishing grounds

Tue, 26/06/2018 - 16:58
5 June 2018

The Directorate General of Fisheries and Maritime Affairs of the Department of Agriculture, Livestock, Fisheries and Food, the Institute of Marine Sciences and the fishermen from Blanes, Palamós, Roses, Port de la Selva and Llançà join in an unique initiative in the Mediterranean region: 500 km2 of Girona’s coastline will be managed by the same fishing sector and measures will be implemented to enhance the sustainability and preservation of marine resources.
