Ecological long-term research at Helgoland (German Bight,North Sea): retrospect and prospect—an introduction

This paper summarizes and evaluates ecological long-term observations at the island of Helgoland (German Bight, North Sea). It is an introduction to a series of seven contributions to an issue of Helgoland Marine Research (vol. 58, no. 4) dealing with observations on the physico-chemical environment and the local biota (pelagic bacteria, phytoplankton, zooplankton, macroalgae, macrozoobenthos). More than 150 years of research at Helgoland (at the Biologische Anstalt Helgoland, BAH, since 1892), and particularly the Helgoland Roads time-series which started in 1962, has provided a multitude of data which represents a valuable basis for analysing past changes, evaluating the present status and predicting future changes in ecosystem parameters. Predicting the consequences of the recent rapid ecological change on regional and global scales requires increased efforts of focus on long-term ecological observations. Future efforts in this field will rely on the application of innovative advanced technology and on the concerted activities of a large number of institutions which only collectively can establish the large-scale patterns of temporal and spatial change in ecosystem functions.     

Five scientists on excursion — a picture of marine biology on Helgoland before 1892

Five scientists on excursion — a picture of marine biology on Helgoland before 1892. The picture, of which several variant poses with minor differences exist, is a photograph taken on Helgoland in September, 1865. The original is to be found in the collections of the Ernst-Haeckel-Haus in Jena. The photograph shows only a few objects and fewer persons, but they are arranged like a bouquet: in front, collecting vessels; behind, grouped around a table, five scientists, Dohrn, Greeff, Haeckel, Salverda, Marchi. They hold up their catching nets like insignia, identifying their basic activity. This photograph is a unique document for the marine biological research on Helgoland before 1892. Furthermore, it illustrates a time and place for the birth of the idea of establishing the world's most famous marine biological station, the Stazione Zoologica di Napoli.     

Helgoland und die Erforschung der marinen Benthosalgen

Early phycological research on the island of Helgoland was performed by amateur phycologists from the adjacent coastal regions of Germany (Bremen, Hamburg, Lower Saxony and Schleswig-Holstein). These pioneers were followed by professionals, and by collectors from the mainland universities, particularly from Berlin. This second phase group includes the naturalist Christian Gottfried Ehrenberg, the zoologists Johannes Müller, Ernst Haeckel and Anton Dohrn, and the botanists Alexander Braun, Nathanael Pringsheim, and Ferdinand Cohn. The leading marine phycologist in Germany, towards the end of the 19th century, was Johannes Reinke, who finally worked at the University of Kiel. Paul Kuckuck's doctoral thesis had been supervised by Reinke who recommended him for the post of the first curator of botany at the Biological Station of Helgoland, which was founded in 1892. Kuckuck worked on the island from 1892 to 1914. After World War I, and after Kuckuck's untimely death, Wilhelm Nienburg became the second curator of botany on Helgoland, from 1921 to 1923. The next permanent phycologist on the island, from 1925 to 1936, was Ernst Schreiber. He was followed in 1936 by Peter Kornmann, who retired in 1972 but still continues as a research worker, together with Paul-Heinz Sahling, who started to work as a technical assistant under the guidance of Ernst Schreiber in 1927.

On the relation between the Institut für Meereskunde in Berlin and the Biologische Anstalt Helgoland

The “Institut für Meereskunde” (IfM) in Berlin, founded in 1900, first took up marine biology as a section of its museum, in which emphasis was placed on the environment and the components of local ecosystems rather than on extraordinary species. The first joint research project of the Biologische Anstalt Helgoland (BAH) and the IfM in Berlin was instigated by the physicist A. Merz; it included several time-series of hydrographical and biological samples at fixed stations (light vessels) in the German Bight. When plans were made to establish a biological station in Constantinople during World War I, the colleagues in Berlin tried to change it into an integrated physicalbiological station, in which biological research would concentrate on revealing the laws of nature rather than simply describing the biosphere. During the recession after the war, the Prussian government was anxious to unite both institutions in order to save money. However, Mielck of the BAH succeeded in preventing the take-over by the Institute in Berlin. The relation between the two institutes stayed cool up to the destruction of the latter in 1945.     

History of American Marine Biology and Marine Biology Institutions Introduction: Origins of American Marine Biology

SYNOPSIS.In the 1840s and 1850s professional naturalists dredgedshallow sea-water on the eastern coast of the United Statesto obtain marine specimens for teaching and research. In 1871Spencer F. Baird, first U.S. Commissioner of Fish and Fisheries,organized amarine biological laboratory at Woods Hole, Massachusetts,for basic biological research as well as for practical fisherybiology. In 1873 Louis Agassiz established his summer marinestation for teachers on Penikese Island, which stimulated others,especially some of his former students, to do likewise alongthe eastern coast in subsequent years, culminating in the renownedMarine Biological Laboratory at Woods Hole (1888). On the Pacificcoast the pioneer marine laboratories were the Hopkins MarineLaboratory (1892) and the prestigious Scripps Institute of Oceanographyin California (1903), and the Puget Sound Biological Station,later known as the Friday Harbor Laboratories, in Washington(1903). Today, over 50 marine laboratories are in operationin the 21 contiguous coastal states for education and researchin marine biology     

Web-based telemicroscopy

By taking advantage of network-based computing and the recent developments in Web interfaces, centralized research facilities housing specialized and unique imaging instruments along with associated high-performance computing can be made available to researchers for use from their own laboratories. In addition to increasing access and utilization of these facilities, operation over the Internet is expected to enhance research by facilitating collaboration between researchers. We describe the implementation of a platform-independent Web-based system written in Java that supplements automated functions with video-guided interactive, collaborative remote control and data acquisition from an intermediate-high-voltage electron microscope.     

Monitoring activities in the Federal Republic of Germany pursuant to international conventions and national legislation

The main activities of the Federal Republic of Germany regarding the monitoring of the pollution of the North Sea and the Baltic Sea are described. Reference is also made to research projects concerned with the investigation of the processes of transportation and transformation of harmful substances in the marine ecosystem. Political conclusions drawn by the Federal Government are mentioned. Environmental protection measures are only dealt with marginally; combatting measures are not dealt with.

The marine macroalgae of Helgoland (North Sea): an annotated list of records between 1845 and 1999

The earliest known records of marine macroalgae from Helgoland (German Bight, North Sea) date from the mid-19th century. Since then, 274 marine macroalgal species have been reported: 77 species of Chlorophycota, 100 species of Phaeophycota and 97 species of Rhodophycota. Additionally 11 species were only recorded as drift and 51 species as doubtful for Helgoland. The remains of the herbarium of Paul Kuckuck, the first curator for botany at the Helgoland Biological Station between 1892 and 1914, are still located there and consist of 173 macroalgal species from Helgoland. On comparing this 100-year-old herbarium and other old sources with recent macroalgal records, it became clear that changes in species composition have occurred. After World War II, several species such as Arthrocladia villosa, Corynophlaea crispa, Cutleria multifida, Eudesme virescens, Mesogloia vermiculata, Sporochnus pedunculatus, Antithamnion cruciatum, Apoglossum ruscifolium, Chondria dasyphylla, Helminthora divaricata, Jania rubens and Osmundea ramosissima were not found again. Other species such as Dictyota dichotoma, Leathesia difformis, Stictyosiphon soriferus, Helminthocladia calvadosii and Scinaia furcellata became very rare. Significantly, perhaps, most of these species have a heteromorphic life history with the appearance of the macroscopic phase restricted to (spring and) summer. Many new species of green algae were recorded for Helgoland after 1959, due to new substrata and the research activities of Peter Kornmann, curator for botany after 1959, and Paul-Heinz Sahling his technical assistant. Introductions of species during the considered time period were: Bonnemaisonia hamifera, Codium fragile, Mastocarpus stellatus and Sargassum muticum. Type material of the following species is located at the Marine Biological Station at Helgoland: Mikrosyphar porphyrae, Porphyra insolita and Ulva tenera.

Fundamentals of an applied ecosystem research project in the Wadden Sea of Schleswig-Holstein

The aims, content, and organisatory structure of a proposed interdisciplinary ecosystem research project in the Wadden Sea of Schleswig-Holstein (W. Germany) are briefly presented. The project will include research on both fundamental as well as applied aspects of the Wadden Sea ecosystems and their interaction with local human activities. In contrast to most of the other completed or currently running ecosystem research projects on tidal coasts, a considerable part of the scientific work will also deal with aspects of ecosystem management and protection of the various marine and semiterrestrial habitats of the Wadden Sea. Considerable attention is paid to theoretical and methodological aspects of research on ecosystems and landscape units. In particular, the adoption of a hierarchical view of complex biological and environmental systems is recommended.

The MIT user center for neutron capture therapy research

Neutron capture therapy (NCT) research encompasses a wide range of preclinical and clinical studies needed to develop this promising but complex cancer treatment. Many specialized facilities and capabilities including thermal and epithermal neutron irradiation facilities, boron analysis, specialized mixed-field dosimetry, animal care facilities and protocols, cell culture laboratories, and, for human clinical studies, licenses and review board approvals are required for NCT research. Such infrastructure is essential, but much of it is not readily available within the community. This is especially true for neutron irradiation facilities, which often require significant development and capital investment too expensive to duplicate at each site performing NCT research. To meet this need, the NCT group at the Massachusetts Institute of Technology (MIT) has established a User Center for NCT researchers that is already being accessed successfully by various groups. This paper describes the facilities, capabilities and other resources available at MIT and how the NCT research community can access them.     

Comparative analysis of European wide marine ecosystem shifts: a large-scale approach for developing the basis for ecosystem-based management

Abrupt and rapid ecosystem shifts (where major reorganizations of food-web and community structures occur), commonly termed regime shifts, are changes between contrasting and persisting states of ecosystem structure and function. These shifts have been increasingly reported for exploited marine ecosystems around the world from the North Pacific to the North Atlantic. Understanding the drivers and mechanisms leading to marine ecosystem shifts is crucial in developing adaptive management strategies to achieve sustainable exploitation of marine ecosystems. An international workshop on a comparative approach to analysing these marine ecosystem shifts was held at Hamburg University, Institute for Hydrobiology and Fisheries Science, Germany on 1-3 November 2010. Twenty-seven scientists from 14 countries attended the meeting, representing specialists from seven marine regions, including the Baltic Sea, the North Sea, the Barents Sea, the Black Sea, the Mediterranean Sea, the Bay of Biscay and the Scotian Shelf off the Canadian East coast. The goal of the workshop was to conduct the first large-scale comparison of marine ecosystem regime shifts across multiple regional areas, in order to support the development of ecosystem-based management strategies.     

Challenges for proteomics core facilities

Many analytical techniques have been executed by core facilities established within academic, pharmaceutical and other industrial institutions. The centralization of such facilities ensures a level of expertise and hardware which often cannot be supported by individual laboratories. The establishment of a core facility thus makes the technology available for multiple researchers in the same institution. Often, the services within the core facility are also opened out to researchers from other institutions, frequently with a fee being levied for the service provided. In the 1990s, with the onset of the age of genomics, there was an abundance of DNA analysis facilities, many of which have since disappeared from institutions and are now available through commercial sources. Ten years on, as proteomics was beginning to be utilized by many researchers, this technology found itself an ideal candidate for being placed within a core facility. We discuss what in our view are the daily challenges of proteomics core facilities. We also examine the potential unmet needs of the proteomics core facility that may also be applicable to proteomics laboratories which do not function as core facilities.     

PI Recruitment

Wuhan Institute of Virology, Chinese Academy of Sciences (CAS) was founded in 1956. With scientific research elitists, Wuhan Institute of Virology is the only comprehensive institute carrying out fundamental researches on virology in CAS. The institute offers a highly interactive research environment and outstanding research facilities,including BSL3 laboratories. According to the national strategic need, Wuhan Institute of Virology has recently extended its emphasis from general virology to human virology and emerging diseases research.     

A perspective on the value of aquatic models in biomedical research

For at least 150 years, biological scientists have congregated at marine laboratories, located at the edge of the sea, to explore aquatic life. The purpose of this minireview is to offer a brief perspective on the relevance of this activity to our knowledge of human physiology and disease, drawing heavily on the experience of the authors and without attempting to offer a comprehensive history of the many contributions of marine models to biomedical research.     

Biologistes sans frontières

Junior researchers are encouraged to gain experience abroad, and for senior scientists, sabbaticals remain popular. France has taken the next step in fostering international exchange, by supporting long-term collaborations with foreign laboratories and by creating research units abroad.     

Testing the beneficial acclimation hypothesis and its alternatives for locomotor performance

The beneficial acclimation hypothesis (BAH) is controversial. While physiological work all but assumes that the BAH is true, recent studies have shown that support for the BAH is typically wanting. The latter have been criticized for assessing the benefits of developmental plasticity rather than acclimation. Here we examine the BAH within a strong inference framework for five congeneric species of ameronothroid oribatid mites that occupy marine to terrestrial habitats. We do so by assessing responses of maximum speed, optimum temperature, and performance breadth, measured from -10 degrees C to 35 degrees C, to four treatment temperatures (0 degrees , 5 degrees , 10 degrees , and 15 degrees C). We show that the BAH and its alternatives often make similar empirical predictions. Weak beneficial acclimation is characteristic of one of the more marine species. In the other two upper-shore and marine species, evidence exists for deleterious acclimation and the colder-is-better hypothesis. In the two fully terrestrial species, there is no plasticity. Lack of plasticity is beneficial when cue reliability is low or costs of plasticity are high, and the former seems plausible in terrestrial habitats. However, weak plasticity in the upper-shore/marine species and the absence of plasticity in the terrestrial species might also be a consequence of phylogenetic constraint.     

Working with living krill - the people and the places

The fascination of Antarctic scientists with Antarctic krill and their capabilities has a long and varied history, and prompted many scientists to maintain and manipulate krill under laboratory conditions. Starting in the Discovery era with Mackintosh at the King Edward Point labs on South Georgia, 1930, scientists have collected krill from sailing vessels, small boats, inflatable zodiacs and large ice-breaking vessels. Krill have been maintained in small and large jars, deep rectangular tanks, large round tanks and in flow-through and recycling systems. They have been maintained both on board research vessels and in laboratories, in flowing seawater systems at ambient conditions and in temperature-controlled environmental rooms. A few researchers have transported living krill back to their home laboratories, for example tropical laboratories in Japan (Murano) and Australia (Ikeda), temperate laboratories (Nicol) in Australia, a northern European laboratory in Germany (Marschall) and a sunny maritime laboratory in California (Ross and Quetin). The goals have been varied: short-term experiments to understand in situ physiological rates, long-term experiments to test the effects of manipulations or controlled changes in environmental conditions, and behavioral responses. We take you on a brief historical tour as we trace the lineage of modern day research on living Antarctic krill.

Meeresalgen von Helgoland

This report represents a photographic documentation of the more conspicuous species of the marine algal vegetation of the island Helgoland (North Sea), based on collections and observations made since 1959. The catalogue is largely restricted to macroscopic forms, as adequate knowledge of most of the microscopic ones is not yet available. Remarks on some rare species are added in a special chapter; the list includes some 150 species. With a few exceptions, the figures have been obtained from living algae; they illustrate aspects of reproduction and development and, occasionally, demonstrate different seasonal habits. The simplified key may be useful for providing a guide both for naturalists and students of marine phycology. In addition, this algal flora enhances our knowledge of the distribution of benthic species along the European coasts, as the rocky island of Helgoland intervenes between southern Norway and the shores of the English Channel.
