Marine Biodiversity in the Journal of Cadiz

How much biodiversity is in the Gulf of Cadiz ? To this question, scientists can not give a specific answer, or indeed, accurate. There have been some advances very substantial in various habitats and ecosystems, particularly those located in the coastal domain (inter-and subtidal) in the same way that we know enough about the species that live in the fishing grounds. However, this scientific information is quite biased because the method applied to obtain data. These data were obtained primarily demersal trawl gear (see photo attached) justified strategy for the operational context in which they have operated marine research campaigns that have provided the data.

The momentum that has been recently the Project INDEMARES , funded by the English Institute of Oceanography and the European Commission ( Project LIFE + ) and managed by the Biodiversity Foundation , the study of the Gulf of Cadiz, has helped increase our knowledge of particular habitats and the ecosystems that host related to the expulsion of hydrocarbon-laden fluids. The review of resource databases available on the IEO live and conduct further sampling benthic techniques have revealed the existence of a rich biodiversity that can determine a change in the management of applications being developed in some areas of the Gulf of Cadiz.

The difficulties passing the fishing industry in the Gulf, both in the fisheries of bivalves (as the case of venus, almost daily news in Diario de Cádiz) , as in crustaceans, as well as in the tuna and related species, show strong stress that the area is subjected. Not only the extraction activity the cause of this distress, as are many other activities which, presumably, are bidding farewell to biological diversity in the area, with obvious risk of destruction critical habitat. Ocean noise generated by intense vessel traffic affects many species of mammals and sea turtles, numerous submarine cables, pipes and all kinds of structures deposited on the seabed are a threat to the habitats that are extremely sensitive to these activities ... etc, are, together, a real pressure on ecosystems that degrade the marine environment.

say at this stage of life that the marine environment and biodiversity are essential to the development of life on Earth, is obvious, however, should remember from time to time this sort of platitudes and meditate for a while the such actions or attitudes we can take, individually or collectively, to facilitate the protection of marine ecosystems and species that live in them. We therefore ask our social role in safeguarding the species that usually do not see, simply because they inhabit the sea floor, and that when we are above the market stalls or in the seafood. So do not think the trail of destruction they have left behind and that we help to produce if we become responsible consumers.

These issues are those discussed succinctly, the researcher Dr. Díaz-del-Rio Gemar group, in the pages of Journal Cádiz.

INQUA Congress XVIII

Since 1928, INQUA (International Union for Quaternary Research) promotes communication and collaboration in the study of the Quaternary. The current research fields of the INQUA are reflected in its five committees.

• coastal and marine processes. Paleoclimate
Human and Biosphere
Stratigraphy and Chronology
• Terrestrial Processes, Deposits and History

Once every four years around the world cuaternaristas cited in the INQUA Congress to share the results the latest research and develop their agendas for the coming years. In 2011, Congress will be held in Bern, the Swiss capital.

The research field of Coastal and Marine Processes , is more related to the Marine Sciences, and is broken down into the following sessions:

1. Climate and Sea-Level Change During The last 140 ka in
the Mediterranean
2. landscapes and continental shelves Drowned During The last glacial cycles (IGCP526)
3. From the Western Mediterranean to the Caspian Sea: A corridor of palaeoenvironmental change and human response DURING the last 30,000 years
4. records of Late Quaternary coastal evolution
5. Quaternary coastal records of rapid change (co-seismic uplift / subsidence, tsunamis and storm Impacts)
6. jumps Sea-level: evidence from Quaternary proxy

records in the first two sessions involved in coordinating the English investigators, Dr. Teresa Bardají (UHA) and Dr. Francisco José Lobo Sánchez (IACT-CSIC), respectively.

an affair with student Diversification of 3 º E IES Sierra de Guadarrama in which we will work with a class blog where they will be the students themselves who have to manage entries, upload your work, share activities, etc. The project, which we will profile along the course, we called Blog Diversoto. If you want to know more about it feel free to visit him in http://diversoto.blogspot.com and participate by reading your entries and comment on them. All suggestions are welcome.
