Invasive non‐native species likely to threaten biodiversity and ecosystems in the Antarctic Peninsula region

The Antarctic is considered to be a pristine environment relative to other regions of the Earth, but it is increasingly vulnerable to invasions by marine, freshwater and terrestrial non‐native species. The Antarctic Peninsula region (APR), which encompasses the Antarctic Peninsula, South Shetland Islands and South Orkney Islands, is by far the most invaded part of the Antarctica continent. The risk of introduction of invasive non‐native species to the APR is likely to increase with predicted increases in the intensity, diversity and distribution of human activities. Parties that are signatories to the Antarctic Treaty have called for regional assessments of non‐native species risk. In response, taxonomic and Antarctic experts undertook a horizon scanning exercise using expert opinion and consensus approaches to identify the species that are likely to present the highest risk to biodiversity and ecosystems within the APR over the next 10 years. One hundred and three species, currently absent in the APR, were identified as relevant for review, with 13 species identified as presenting a high risk of invading the APR. Marine invertebrates dominated the list of highest risk species, with flowering plants and terrestrial invertebrates also represented; however, vertebrate species were thought unlikely to establish in the APR within the 10 year timeframe. We recommend (a) the further development and application of biosecurity measures by all stakeholders active in the APR, including surveillance for species such as those identified during this horizon scanning exercise, and (b) use of this methodology across the other regions of Antarctica. Without the application of appropriate biosecurity measures, rates of introductions and invasions within the APR are likely to increase, resulting in negative consequences for the biodiversity of the whole continent, as introduced species establish and spread further due to climate change and increasing human activity.     

A Note on the United States and the Law of the Sea: Looking Back and Moving Forward

Since the Antarctic Treaty was negotiated in 1959, there have been substantial developments in the law of the sea. One of the most significant developments has been the recognition granted to coastal state entitlements to claim a range of offshore maritime areas. Yet, one of the principal aims of the Antarctic Treaty was to eliminate sovereignty disputes between territorial claimants, and the treaty placed limitations on the assertion of new claims. Nevertheless, most Antarctic territorial claimants have asserted some form of Antarctic maritime claim. This article particularly considers Australia's position toward maritime claims offshore the Australian Antarctic Territory (AAT). It reviews the limitations imposed by the Antarctic Treaty, the difficulties in determining baselines in Antarctica, Australia's practice in declaring Antarctic maritime claims, and the potential range of maritime boundaries that Australia may one day have to delimit with neighboring states in the Southern Ocean.     

The politics of a new legal order for fisheries

Illegal, unreported, and unregulated (IUU) Fishing is considered a major threat to high seas fish stocks. Each of the the international regional fishery management organizations (RFMOs) are combating some form of IUU fishing and this led the Food and Agriculture Oranization of the United Nations (FAO) to adopt the International Plan of Action to Deter, Prevent and Eliminate IUU Fishing (IPOA-IUU). This article will analyze the issues involved with IUU fishing, examine the recommendations in the IPOA, and consider examples of successful management and enforcement measures in use by states and RFMOs. Finally, recent developments in China will be viewed as an example of how international cooperation is contagious.     

The 2001 UNESCO Underwater Cultural Heritage Convention and Taiwan's Domestic Legal Regime

The United Nations Educational, Scientific and Cultural Organization (UNESCO) adopted the Convention on the Protection of the Underwater Cultural Heritage (the UCH Convention) on November 2, 2001. The Convention created a comprehensive legal framework for the preservation, protection, and management of underwater cultural heritage. This article illustrates that the UCH Convention not only supplements, but also substantively amends, the relevant rules contained in the 1982 United Nations Convention on the Law of the Sea. This article, using the domestic legislation of Taiwan as an example, demonstrates some of the difficulties of implementing the UCH Convention into national law.

Article 297 of the United Nations Convention on the Law of the Sea and the Scope of Mandatory Jurisdiction

This article assesses the scope and content of the automatic exceptions contained in Article 297 of the UN Convention on the Law of the Sea to the compulsory procedures established in Section 2 of Part XV. The Convention's drafting history is examined with a view to determining the validity of the diametrically opposed readings of Article 297(1) endorsed by Annex VII Tribunals in the Southern Bluefin Tuna Award and the Chagos Marine Protected Area (MPA) Award. The interpretation favoured in the Chagos MPA Award—that mandatory jurisdiction is not restricted to the three cases expressly enumerated in Article 297(1)—is consistent with the textual evolution of Part XV. The article situates the approach adopted by the Chagos Tribunal within a wider normative tradition, which holds that adjudicative jurisdiction arises in default of positive textual authorzsation (unless it has been explicitly excluded). It is argued that this approach should be embraced by courts and tribunals when interpreting the Convention's provisions, as it accords with the drafters' aspirations and it serves to strengthen the international Rule of Law.     

Economic Analysis of the Legal Regimes Governing Salvage of Historic Shipwrecks

This article offers an economic analysis of the international and U.S. laws governing the recovery of archaeological data from historic shipwrecks. The framework combines values of treasure salvage and archaeological knowledge. It is suggested that U.S. salvage law, sometimes extended to international waters, gives insufficient protection to archaeological value, but that UNESCO's Convention on the Protection of the Underwater Cultural Heritage goes too far in the other direction. Two other legal regimes (government-salvager and interstate agreements) are shown to have the potential to maximize the social values of historic shipwrecks. It is also suggested that a move towards maximizing social values would be promoted if the U.S. admiralty courts tied the size of salvage awards more closely to the quality of the archaeological work performed.     

Jurisdiction Over Underwater Cultural Heritage in the EEZ and on the Continental Shelf: A Perspective From the Practice of States Bordering the South China Sea

Abstract

The Chinese initiative of constructing the 21st Century Maritime Silk Road could be identified as a new chance to promote the protection of underwater cultural heritage (UCH) in the South China Sea. However, uncertainties concerning the jurisdictional issue over the UCH in the exclusive economic zone (EEZ) or on the continental shelf constitute an obstacle. The Convention on the Protection of Underwater Cultural Heritage has, to some extent, enlarged the coastal state’s jurisdiction. State practice differs on this issue. This article focuses on the domestic legislations of states bordering the South China Sea related to the jurisdiction over UCH found in their EEZ or on their continental shelf.

Agroforestry and Biodiversity Conservation – Traditional Practices, Present Dynamics, and Lessons for the Future

The environmental services that agroforestry practices can provide, and especially their potential contribution to the conservation of biodiversity, have only recently attracted wider attention among agroforestry and conservation scientists. This new view is consistent with the ecosystem approach to natural resource management advocated by the Convention on Biological Diversity. This collection of six papers, which is based on a Workshop held in June–July 2004, brings together studies of biodiversity impacts of traditional agroforestry practices from Central and South America, Africa and Asia. The contributions highlight the considerable potential of traditional agroforestry practices to support biodiversity conservation, but also show their limits. These include the importance of sufficient areas of natural habitat and of appropriate hunting regulations for maintaining high levels of biodiversity in agroforestry land use mosaics, as well as the critical role of markets for tree products and of a favourable policy environment for agroforestry land uses. In combination the case studies suggest that maintaining diversity in approaches to management of agroforestry systems, along with a pragmatic, undogmatic view on natural resource management, will provide the widest range of options for adapting to changing land use conditions.     

The case in international law for Canada's extension of fisheries jurisdiction beyond 200 miles

In March 1995, Canadian fisheries authorities boarded and arrested the Spanish fishing vessel, Estai, outside the Canadian 200‐mile zone on the Grand Banks, an event that served to focus world attention on a dispute that had its origins in the failure of the 1982 United Nations Convention on the Law of the Sea to implement an effective conservation and management regime for fish stocks on the high seas, particularly with respect to fish stocks that straddle coastal states’ exclusive economic zones. This article examines the origins of the dispute, including the allegations relating to overfishing of North Atlantic Fisheries Organization‐recommended quotas, the background to the vessel's arrest, and the subsequent confrontation that occurred, both at diplomatic levels and on the high seas, between Canada and the European Union. An analysis is made of the case in international law for Canada's extension of jurisdiction beyond 200 miles pursuant to the provisions of Section 5 of the Coastal Fisheries Protection Act. Finally, the article examines the implications of the recently concluded Agreement on the Conservation and Management of Straddling Fish Stocks and Highly Migratory Fish Stocks for disputes of the kind that arose in the present case.     

E-photosynthesis: web-based platform for modeling of complex photosynthetic processes

E-photosynthesis framework is a web-based platform for modeling and analysis of photosynthetic processes. Compared to its earlier version, the present platform employs advanced software methods and technologies to support an effective implementation of vastly diverse kinetic models of photosynthesis. We report on the first phase implementation of the tool new version and demonstrate the functionalities of model visualization, presentation of model components, rate constants, initial conditions and of model annotation. The demonstration also includes export of a model to the Systems Biology Markup Language format and remote numerical simulation of the model.     

Metagenomic analysis of virulence-associated and antibiotic resistance genes of microbes in rumen of Indian buffalo (Bubalus bubalis)

A major research goal in rumen microbial ecology is to understand the relationship between community composition and its function, particularly involved in fermentation process is of a potential interest. The buffalo rumen microbiota impacts human food safety as well as animal health. Although the bacteria of bovine rumen have been well characterized, techniques have been lacking to correlate total community structure with gene function. We applied 454 next generations sequencing technology to characterize general microbial diversity present in buffalo rumen metagenome and also identified the repertoire of microbial genes present, including genes associated with antibiotic resistance and bacterial virulence. Results suggest that over six percent (6.44%) of the sequences from our buffalo rumen pool sample could be categorized as virulence genes and genes associated with resistance to antibiotic and toxic compounds (RATC), which is a higher proportion of virulence genes reported from metagenome samples of chicken cecum (5.39%), cow rumen (4.43%) and Sargasso sea (2.95%). However, it was lower than the proportion found in cow milk (11.33%) cattle faeces (8.4%), Antarctic marine derived lake (8.45%), human fecal (7.7%) and farm soil (7.79%). The dynamic nature of metagenomic data, together with the large number of RATC classes observed in samples from widely different ecologies indicates that metagenomic data can be used to track potential targets and relative amounts of antibiotic resistance genes in individual animals. In addition, these data can be also used to generate antibiotic resistance gene profiles to facilitate an understanding of the ecology of the microbial communities in each habitat as well as the epidemiology of antibiotic resistant gene transport between and among habitats.     

On the control between cell-mediated, IgM and IgG immunity

An hypothesis is proposed here describing some of the conditions that determine the type of response an antigen will induce, and explaining how the induction of one type of immunity affects the induction of other types of immunity. In more detail, the hypothesis attempts to account for the following observations: Some antigens induce only cell-mediated immunity, whereas others can, under different conditions, induce either cell-mediated or humoral immunity. The humoral response to most antigens consists of an initial period of IgM antibody synthesis, followed by a period of IgG synthesis. Some polymeric antigens induce the synthesis of only IgM antibody. There is a tendency for the immune response to an antigen, at a particular time, to be exclusively of the cell-mediated, IgM or IgG type.The hypothesis may also be relevant to some observations that, I believe, have been incorrectly interpreted to mean that “tolerance” to some antigens requires the presence of T (thymus-derived) cells specific for these antigens. The hypothesis suggests teleological reasons for the existence of the different types of immunity. It also suggests ways of controlling the type of response an antigen induces.     

Predicting the Risk of Suicide by Analyzing the Text of Clinical Notes

We developed linguistics-driven prediction models to estimate the risk of suicide. These models were generated from unstructured clinical notes taken from a national sample of U.S. Veterans Administration (VA) medical records. We created three matched cohorts: veterans who committed suicide, veterans who used mental health services and did not commit suicide, and veterans who did not use mental health services and did not commit suicide during the observation period (n = 70 in each group). From the clinical notes, we generated datasets of single keywords and multi-word phrases, and constructed prediction models using a machine-learning algorithm based on a genetic programming framework. The resulting inference accuracy was consistently 65% or more. Our data therefore suggests that computerized text analytics can be applied to unstructured medical records to estimate the risk of suicide. The resulting system could allow clinicians to potentially screen seemingly healthy patients at the primary care level, and to continuously evaluate the suicide risk among psychiatric patients.     

The complete mitochondrial genome sequence of the world's largest fish,the whale shark (Rhincodon typus), and its comparison with those of related shark species

The whale shark (Rhincodon typus) is the largest extant species of fish, belonging to the order Orectolobiformes. It is listed as a “vulnerable” species on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species, which makes it an important species for conservation efforts. We report here the first complete sequence of the mitochondrial genome (mitogenome) of the whale shark obtained by next-generation sequencing methods. The assembled mitogenome is a 16,875 bp circle, comprising of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. We also performed comparative analysis of the whale shark mitogenome to the available mitogenome sequences of 17 other shark species, four from the order Orectolobiformes, five from Lamniformes and eight from Carcharhiniformes. The nucleotide composition, number and arrangement of the genes in whale shark mitogenome are the same as found in the mitogenomes of the other members of the order Orectolobiformes and its closest orders Lamniformes and Carcharhiniformes, although the whale shark mitogenome had a slightly longer control region. The availability of mitogenome sequence of whale shark will aid studies of molecular systematics, biogeography, genetic differentiation, and conservation genetics in this species.
