An international scientific team, with a large contribution of ICM-CSIC researchers, has obtained the genome of several marine bacterivorous protists and has compared them to the genetic data of natural microbial communities. The results unveil how these bacterivorous distribute across the different regions of the ocean and supports the idea that each species has a specific role in the microbial plankton.

Terrestrial and marine animals and plants have adapted to different environmental conditions and perform different roles within ecosystems, which determines their distribution on the different regions of the Earth planet. Similarly, it is known that ocean plankton, which includes many microscopic organisms (among them, protists or unicellular eukaryotes) is not a vast mass of individuals randomly grouped. On the contrary, each...

A group of international researchers, led by AZTI scientists, and with a large contribution of ICM-CSIC researches show in a paper published in the latest issue of Nature Communications that the size of marine plankton is key to its global dispersal and distribution. It is an important discovery because plankton form the base of the food chain in the sea, produce 50% of the oxygen we breathe and also remove CO2 from the atmosphere. These functions depend on the distribution of the different plankton species and on their body size.

In the study entitled “Large-scale ocean connectivity and planktonic body size”, an international team of researchers has discovered a negative relationship between the dispersal scales of various plankton and micro-nekton groups and their body size. The groups that were addressed included...

The role of viruses on marine microbial communities has been widely studied in the coastal or surface zones of the oceans but the evaluation of viruses in the deep ocean is scarce. One of the main objectives of the Malaspina 2010 Circumnavigation Expedition, led by the Spanish National Research Council (CSIC), was to sample the deep ocean and to study the life strategies of the viruses that live there. The results of the study, published in the journal Science Advances, show that viral lysis, or a process that breaks down cells and produces the release of intracellular material, is an important phenomenon in the dark ocean and it is also a significant agent of mortality of the prokaryotic communities (bacteria). Therefore, this viral activity play a key role in the in the production of dissolved organic carbon and nutrients in the...

The fifth edition of the "Ramon Margalef Summer Colloquia" (RMSC) will begin on Monday 3 of July, organized by the Institut of Marine Science (ICM-CSIC) and the Catalan Association of Oceanographers (ACOIO). Since its first edition in 2013, every summer the RMSC gathers junior and senior oceanographers to exchange ideas on ocean research.

This year's colloquium, coordinated by ICM oceanographers Josep Lluís Pelegrí and Celia Marrasé, will focus on " spatial and temporal patterns in physical-biological ocean processes". The objective is to promote an interdiciplinary approach to the physical and biological factors that favour the energy fluxes in ecosystems at all spatial and temporal scales, exploring how the network of interactions traduces in much more than the lineal addition of...

The Institute of Marine Sciences (ICM-CSIC) is part of PerformFISH, a new H2020 European project focus on developing consumer driven aquaculture production by integrating innovative approaches that can help ensure European sea bream and sea bass aquaculture businesses are sustainable and competitive. It is coordinated by the University of Thessaly (Greece) and its consortium brings together 28 partners from 10 different countries, which also include the Torre de la Sal Aquaculture Institute (IATS-CSIC), which coordinates CSIC's participation in the project, and the Marine Research Institute of Vigo (IIM-CSIC).

The farming of sea bass and sea bream is an important sector in the Mediterranean, contributing significantly to wealth and job creation in rural and coastal areas. Sea bream and sea bass are by volume the third (36.4...
