Marine Biodiversity Exposed

17.05.2006


Top European marine biodiversity experts in Lecce, Italy.



Marine biodiversity was ‘exposed’ on a number of different levels in Lecce, Italy 8th-11th May 2006, where MarBEF (Marine Biodiversity and Ecosystem Functioning) a European Network of Excellence held its third general assembly in a ‘conference style’ meeting. On the agenda were talks by members on their research varying from ‘The paradox of the plankton’ and ‘The role of native and/or invasive ecosystem engineers in explaining biodiversity’ through to ‘Marine Biological Valuation: an integrated view on nature’s intrinsic value‘.

Over 1600 new marine species a year.


Participants heard Phillipe Bouchet say how “the number of marine species can now be estimated to be as low as 230,000 species” (give or take 20,000 species) with over 1,600 marine species being discovered each year. A breakdown by taxa confirms and informs conventional wisdom. Crustaceans and molluscs together account for nearly half of the new species descriptions each year, which is expected, and there are five times as many fish described yearly as there are nematodes, which is unexpected.

Diatoms responsible for copepod abnormalities.

We heard how integration is the key to the success of the research projects within the network including ROSEMEB, a project involving 8 MarBEF institutes that is investigating the role of secondary products in ecosystem biodiversity. A recent study by ROSEMEB involving diatom-copepod interactions challenges the traditionally accepted fact that diatoms provide the bulk of the food that sustains the marine food chain to top consumers and fisheries. Adrianna Iarnora presented results showing how these small unicellular algae possess anti-mitotic properties (i.e. they can interfere with cell division) similar to the cytotic compounds isolated from numerous marine and terrestrial higher plants. In fact, when copepods, the principal predators of diatoms, are fed certain diatom diets, they produce abnormal eggs that either fail to develop to hatching or hatch into malformed nauplii that die soon afterwards.

Influential aliens.

Vadim Panov and Tamara Shiganova told of the patterns and consequences of alien species invasions in coastal ecosystems of European Russia. They revealed the importance of the connectivity of southern seas (Black, Azov and Caspian) with the northern (Black and white seas) via the complicated system of inland waterways, which represent the European “Northern Invasion Corridor”. Also, how the consequences of some keystone invasive species invasions for coastal systems can be severe, as demonstrated in the case of the invasion of the Atlantic ctenophore Mnemiopsis leidyi in the Black and Caspian Seas.

Future for marine biodiversity network debated.

A round table discussion on “Towards the conceptual unification of biodiversity and ecosystem functioning” rounded off 2 days of presentations with lively contributions from the floor. Participants over the course of the assembly heard over 30 talks on the three different research themes within MarBEF (Patterns in Biodiversity, Socio-economics of Biodiversity and Biodiversity and Ecosystem Functioning) followed by a poster session that incorporated over 40 posters. Executive and steering meetings were held either side of the presentations allowing for ease of management and planning for the year ahead. A successful and ‘effective’ assembly was the general consensus of the participants.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
