Implementation of Existing International Legal Instruments for Conservation and Sustainable Uses of Marine Biodiversity in Areas beyond National Jurisdiction: A Case Study of the OSPAR Convention
The states of the world face the new challenge of attempting to prevent the global loss of marine biodiversity by protecting the 64% of the surface area of the oceans that lies beyond national jurisdiction. With this aim, various regional agreements have been negotiated to commit states to set up representative networks of marine protected areas (MPAs). The aim of this note is to explain how it was possible to designate six MPAs in the high sea under the OSPAR Convention and some of the challenges this process raised.
Marine Protected Areas on the High Seas: Some Legal and Policy Considerations
The 2003 meeting of the United Nations Open-Ended Informal Consultative Process on Oceans and the Law of the Sea made a call to explore a range of tools for the protection and management of vulnerable and threatened marine ecosystems and biodiversity beyond national jurisdiction. To achieve this aim, the establishment of marine protected areas (MPAs) on the high seas not only fully complies with customary international law, but is also the subject-matter of specific obligations arising under a number of treaties (starting from UNCLOS Art. 194, para. 5). Today the time-honoured concept of freedom of the sea is to be understood in the context of the present range of marine activities and in relation to all the potentially conflicting uses and interests, such as the protection of the marine environment and the sound exploitation of marine living resources. The 1995 Protocol Concerning Specially Protected Areas and Biological Diversity in the Mediterranean is an interesting precedent on the issue of MPAs on the high seas.
Die Populationsdynamik Von Canthocampt Us Staphylinus (Jurine) (Copepoda, Harpacticoida) Im Litoral Des Bodensees
The population dynamics of Canthocamptus staphylinus in the littoral zone of Lake Constance are described (fig. 2). Adult animals aestivate as cysts. The main part of the population emerges from the cysts in autumn. During the resting stage and the first spell after emerging, mortality is very low (fig. 3). Reproduction, expressed as numbers of ovigerous females, begins in November and reaches its maximum in January. The new generation becomes adult in May/June and encysts without previous reproduction. According to Sarvala (1979) it may be possible, that in littoral populations dormancy is induced by long day periods and temperatures of over 12° C (figs. 1, 2). In the profundal zone C. staphylinus also forms cysts, however, both light and temperature are not likely to induce this stage in depths of over 60 m.
