The Continental Shelf Beyond 200 nm: Innovations in Art. 76 UNCLOS

International institutions are powerful players on the world stage, and every student of international law requires a clear understanding of the forces that shape them. For example, with increasing global influence comes the need for internal control and accountability. This thought-provoking overview considers these and other forces that govern international institutions such as the UN, EU and WTO, and the complex relationship that exists between international organizations and their member states. Covering recent scholarly developments, such as the rise of constitutionalism and global administrative law, and analysing the impact of important cases, such as the ICJ's Genocide case (2007) and the Behrami judgment of the European Court of Human Rights (2007), its clarity of explanation and analytical approach allow students to understand and think critically about a complex subject.

Abstract Rhodolith beds are important marine benthic ecosystems, representing oases of high biodiversity among sedimentary seabed environments. They are found frequently and abundantly, acting as major carbonate 'factories' and playing a key role in the biogeochemical cycling of carbonates in the South Atlantic. Rhodoliths are under threat due to global change (mainly related to ocean acidification and global warming) and local stressors, such as fishing and coastal run-off. Here, we review different aspects of the biology of these organisms, highlighting the predicted effects of global change, considering the additional impact of local stressors. Ocean acidification (OA) represents a particular threat that can reduce calcification or even promote the decalcification of these bioengineers, thus increasing the eco-physiological imbalance between calcareous and fleshy algae. OA should be considered, but this together with extreme events such as heat waves and storms, as main stressors of these ecosystems at the present time, will worsen in the future, especially if possible interactions with local stressors like coastal pollution are taken into consideration. Thus, in Brazil there is a serious need for starting monitoring programs and promote innovative experimental infrastructure in order to improve our knowledge of these rich environments, optimize management efforts and enhance the needed conservation initiatives.
