First Scientific Diving Expedition finds high microbial diversity

Expedition leader Dr. Danny Ionescu retrieves the first samples from freshwater springs at the bottom of the Dead Sea
425 metres below sea level, in the middle of the desert, ten times saltier than the world’s oceans lies the Dead Sea – one of the most hostile places on our planet. A team of researchers from Israel and Germany led by microbiologist Dr. Danny Ionescu from the Max Planck Institute for Marine Microbiology in Bremen dived there for the first time for a systematic scientific exploration of unusual features: freshwater springs on the bottom of the Dead Sea. Where you would expect nothing than mud and bizarre structures made from pure salt crystals – and overall just a few hundred bacteria per liter of water there is more life than previously thought. The first analyses showed that a huge variety of microorganisms thrive right where the springs enter the salt-saturated waters of the Dead Sea. In October 2011 there will be the next mission to these salty depths to investigate how organisms can exist under these extreme conditions. For the divers the conditions are extreme as well. Outside temperatures of 45 °C, 30 percent of salinity and toxic sulfide in the springs pose potential risks. Up to 50 kilogram of weights are needed to immerse a person. Danny Ionescu from MPI Bremen and Christian Lott from HYDRA dive without the usual neoprene suit, but full-face masks and communication systems are a must to protect the scientists under water and connect them to their colleagues at the surface. Be ready to get an up-date on the findings of the next mission by the end of October ...

On behalf of the „Internationale Regierungskommission Alpenrhein“ from 2009 to 2011 HYDRA examined the biological communities of one of the largest alpine rivers. With this study not only the last gaps in our knowledge about the River Rhine fauna could be closed, the team also explored the deficits and the potential for improvements of the river's habitats. The research report was published in July 2011* and provides important information for future water protection control and river development on this regulated and over-exploited mountain river.

More than half of the body of the flatworm Paracatenula is made up by bacterial symbionts. The bacteria and their host are thought to have co-evolved in this symbiosis for over 500 Million years.
As Harald Gruber from the University of Vienna and colleagues report in the online pre-publication of the Proceedings of the National Academy of Sciences small marine flatworms of the genus Paracatenula are stuffed with sulfur-oxidizing bacteria. Many species of these worms are found in sands in front of tropical and subtropical beaches. A common feature they share is that they don’t have a mouth. They don’t eat. Instead, bacterial partners live inside the worm in an organ, called the trophosome. The researchers found that over 50% of the worm’s biomass is actually contributed by the symbionts. Moreover, molecular identification analyses showed, that every worm species harbours its own bacterial species and that the phylogeny of worms and symbionts is congruent for 15 different worm species from the Mediterranean, the Red Sea, the Caribbean and Australia! Harald and colleagues state that this group of flatworms has been in a partnership since the divergence from other flatworms more than 500 Million years ago. They see the small “backyard sand“ worms to be “the oldest known mutualistic bacteria–metazoan symbiosis, likely dating back to the early evolution of bilaterian diversity in the late Ediacaran/early Cambrian.“

Although the species preservation of lake trout was achieved, these salmonids still do not meet with good conditions for their reproduction in the tributaries of Lake Constance. By order of the IBKF (Internationale Bevollmächtigtenkonferenz für die Bodenseefischerei), a team of scientists, which is directed by HYDRA, researches in five chosen rivers with spawning activities. Within the next three years, analyses in the rivers Goldach, Bregenzerach, Leiblach, Argen and Rotach should fill existing gaps of knowledge about migration and reproduction. Aim: Optimizing of renaturation actions for the benefit of a natural reproduction of these impressive fish.

Lake trout can reach a length of almost one meter, for their spawning redds they need at least one square meter of well-oxygenated, loose gravel in the river (photo: S. Werner).

Every two years the Helmholtz Zentrum Geesthacht assigns the GKSS Prize “Intelligible Science“ to young scientists who can proof their ability to present their special research topic in an easily comprehensible way to an audience of non-scientists. This year the first prize with a sum of 2.500 Euro was awarded to the physicist Stefan Krause, who is developing a new hard drive technology. The neurobiologist Dominik Paquet won the second prize of 1.500 Euro with a presentation on Alzheimer's disease of zebra fish. Miriam Weber, lecturer and research coordinator at the HYDRA Field Station on Elba took the jury and the audience "On The Track of the Coral Killer" and told about her science on the effect of sediments on corals as a detective story. She won the third prize of 1.000 Euro. The prize for science communication is awarded every two years to applicants from all over Germany.

Posidonia Day

The HYDRA Institute for Marine Sciences in cooperation with the bar Pino Solitario and the Acquario dell'Elba was inviting the children of the island and interested visitors to delve into the world of the seagrass meadow Posidonia oceanica, the most important shallow-water ecosystem of the Mediterranean Sea.
HYDRA and Aquario dell'Elba staff were kept busy all day long by crowds of children, their teachers and parents around aquaria with pieces of sea grass meadows and typical marine creatures. The direct observation and contact to live organisms normally hidden under the Sea was followed with awe, and myriads of questions and stories of personal experience, by the youngest and the old. A lecture with a video projector presentation was giving additional informations about the ecological interrelations within this important biotope. The visitors were specially attracted by the possibility to immerse themselves into the fascinating microcosm of the seagrass meadow using the six brand new microscopes provided by our partner ZEISS.
The Posidonia Day was a very successful test for the international science outreach initiative "School on the Beach" launched by HYDRA and its partners.


We used the Coastal Clean-up Day as an occasion to combine already existing year-round activities at natural, less accessible beaches with low touristic impact in the vicinity of the HYDRA Field Station on Elba and integrate them into this world-wide environmental project. Thus we were not only collecting garbage but also journaling detailed information by the standards of Oceanconservancy. The data are submitted to the worldwide database of the organization thus giving precious information to governmental authorities and scientific institutions.
This is a project in cooperation with Giovanni Mortula a private nature enthusiast who collects garbage at Le Tombe beach all year round; the HYDRA "Summer-Team" who was collecting and journaling the garbage at Le Tombe during the Coastal Cleanup Day and accomplished the sea transport to the accessible beach of Fetovaia; the association Costa del Sole with Sergio Galli who supported the project; the City Council of Campo nell'Elba taking care of the final disposal of the collected garbage by the initiative of Giovanni Lupi.

Abstract of the program:
"The aim of the workshop is to bring together experts in their field in an intimate and intensive working atmosphere and to open participation to a limited number of junior scientists and outstanding students. In a two-week hands-on workshop all participants should have any possibilities to share knowledge, to learn and teach, to develop new views and to integrate their own capabilities into a broader interdisciplinary framework. Some of the invited scientists have been in the field for well more than 30 years, so another aspect is the transfer of experience as well as maybe unconventional thoughts to the next generation of researchers.
The HYDRA Field Station provides the logistics on Elba and organizes, with the kind support of the Park Authority of the National Park Tuscan Archipelago and the Municipality of Campo nell’Elba, access to the protected area of the Island of Pianosa and set up a field camp."

What do have deep-sea volcanoes, sunken whale carcasses and the shallow-water sand bottoms around the Island of Elba have in common? All these habitats habor a rich community of animals that evolved an obligate relationship with bacteria and thus can gain their nutrition independantly from sunlight, so-called chemosynthetic symbioses.
Nicole Dubilier, Claudia Bergin (both MPI Bremen) and Christian Lott (HYDRA) report in the latest issue of Nature Reviews Microbiology at least 7 animal taxa in which such an intimate relationship with bacteria has been established. It is an extraordinary efficient concept that enables the animals, that have reduced their digestive organs completely or in parts, to gain energy from reduced sulfur compounds or methane, with the help of their little inhabitants. The first discovery of these until then unthinkable life strategies dates 30 years back. In the late 1970s the "Black Smokers", effusions of hot mineral-rich water in the deep-sea of the Galapagos Rift were found, covered with enormous numbers of giant tubeworms and clams. Soon after clams and worms from shallow-water sand bottoms were described, living also in symbiosis with sulfur-oxidizing bacteria. Nicole Dubilier's Symbiosis Research Group at the Max Planck Institute for Marine Microbiology in Bremen, Germany, studies the symbioses of mussels, clams, snails and worms from deep-sea habitats like Mid-Atlantic Ridge volcanoes, methane seeps, whale-falls and sunken wood. In her group Christian Lott investigates the symbiosis of gutless oligochaetes from sand bottoms around the Island of Elba.
