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: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
