    Description: The ability of management strategies to achieve the fishery management goals are impacted by environmental variation and, therefore, also by global climate change. Management strategies can be modified to use environmental data using the "dynamic B 0 " concept, and changing the set of years used to define biomass reference points. Two approaches have been developed to apply management strategy evaluation to evaluate the impact of environmental variation on the performance of management strategies. The "mechanistic approach" estimates the relationship between the environment and elements of the population dynamics of the fished species and makes predictions for population trends using the outputs from global climate models. In contrast, the "empirical approach" examines possible broad scenarios without explicitly identifying mechanisms. Many reviewed studies have found that modifying management strategies to include environmental factors does not improve the ability to achieve management goals much, if at all, and only if the manner in which these factors drive the system is well known. As such, until the skill of stock projection models improves, it seems more appropriate to consider the implications of plausible broad forecasts related to how biological parameters may change in the future as a way to assess the robustness of management strategies, rather than attempting specific predictions per se .

    Description: The application of semantic technologies to the integration of biological data and the interoperability of bioinformatics analysis and visualization tools has been the common theme of a series of annual BioHackathons hosted in Japan for the past five years. Here we provide a review of the activities and outcomes from the BioHackathons held in 2011 in Kyoto and 2012 in Toyama. In order to efficiently implement semantic technologies in the life sciences, participants formed various sub-groups and worked on the following topics: Resource Description Framework (RDF) models for specific domains, text mining of the literature, ontology development, essential metadata for biological databases, platforms to enable efficient Semantic Web technology development and interoperability, and the development of applications for Semantic Web data. In this review, we briefly introduce the themes covered by these sub-groups. The observations made, conclusions drawn, and software development projects that emerged from these activities are discussed.

    Description: Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore, the international Antarctic community came together to ‘scan the horizon’ to identify the highest priority scientific questions that researchers should aspire to answer in the next two decades and beyond. Wide consultation was a fundamental principle for the development of a collective, international view of the most important future directions in Antarctic science. From the many possibilities, the horizon scan identified 80 key scientific questions through structured debate, discussion, revision and voting. Questions were clustered into seven topics: i)Antarctic atmosphere and global connections, ii) Southern Ocean and sea ice in a warming world, iii) ice sheet and sea level, iv) the dynamic Earth, v) life on the precipice, vi) near-Earth space and beyond, and vii) human presence in Antarctica. Answering the questions identified by the horizon scan will require innovative experimental designs, novel applications of technology, invention of next-generation field and laboratory approaches, and expanded observing systems and networks. Unbiased, non-contaminating procedures will be required to retrieve the requisite air, biota, sediment, rock, ice and water samples. Sustained year-round access toAntarctica and the Southern Ocean will be essential to increase winter-time measurements. Improved models are needed that represent Antarctica and the Southern Ocean in the Earth System, and provide predictions at spatial and temporal resolutions useful for decision making. A co-ordinated portfolio of cross-disciplinary science, based on new models of international collaboration, will be essential as no scientist, programme or nation can realize these aspirations alone.

    Description: This book is about management of arctic and northern alpine research stations. It has been produced by a group of station managers participating in the EU 7th Framework Programme Infrastructure project called INTERACT. With this book we want to share the knowledge and experiences we have gained from managing very different research stations in very different environmental and climatic settings. The target audience for the book is mainly managers of research stations in arctic and alpine areas, but we hope that it will also be useful for others involved in science coordination and logistics, e.g. research institutions, chief scientists and expedition planners. The book has been produced mainly based on input from practising station managers being part of ‘INTERACT Station Managers’ Forum (SMF), a forum established to provide a platform for exchange of information between station managers and other participants within INTERACT, and to collect and disseminate knowledge embedded within the network. The scope of this book is to identify and describe best practices and key considerations of relevance to station management under arctic and alpine conditions. As research stations operate under very different legal regimes, financial conditions, environmental and climatic conditions, as well as remoteness, it is not possible to identify specific best practices that fit all stations. Instead, we have described key issues that should be considered and addressed by station management, and supplemented this with examples of good practices from stations operating under different conditions (e.g. different climate, remoteness or size).

    Description: Whaling remains one of the most controversial and divisive aspects of the modern regulation of marine resources. In 1982, the International Whaling Commission, the global management body responsible for the regulation of whale stocks, instituted a moratorium on commercial hunting, which has been in force for almost 20 years. Nevertheless, a number of legal avenues exist within the current international regulatory framework to facilitate a degree of continued hunting. The most contentious of these is the scientific research exemption advanced under Article VIII of the International Convention for the Regulation of Whaling 1946, which provides for the national authorization of permits for lethal research. Japan has undertaken a significant programme of scientific whaling in Antarctica since 1987, despite widespread international criticism and an escalating campaign of nautical obstruction by militant activists, duly generating a long-standing legal dispute with Australia. On 31 March 2014, judgment was rendered by the International Court of Justice, in favour of Australia, ordering Japan to cease and desist its Antarctic whaling programme and refuting Japanese assertions that these activities had been legitimately conducted ‘for the purposes of scientific research’ as permitted under the 1946 Convention

    Description: In this work the management effectiveness of a Cuban MPA is assessed using an interdisciplinary approach. A series of three hypotheses are tested to determine how effective the Punta Frances Marine Protected Area (PFMPA) has been in meeting the multiple objectives of conserving biological diversity and ecological integrity, while allowing for the development of economic opportunities for tourism, and satisfying the needs of local and distant human populations. A new typology of benefits derived from MPAs was produced to provide managers with a practical tool that enable them to: 1) identify the benefits at the early stages of MPA creation, 2) state MPA objectives in a clear and measurable way, 3) assess the effectiveness of their MPA in meeting their management objectives. A new methodology was also developed to assess MPA effectiveness. This methodology constitutes an advancement from previous work, and it is based on qualitative and quantitative measurements of benefits depicted in the proposed typology. It has several advantages over previous methods. One of the main advantages is that it can be applied to assess one single MPA or a group of MPAs in a comparative fashion. The case study analyzed showed that to date, the PFMPA shows little signs of being negatively affected by the recreational SCUBA diving activities for which it was intended, given that no significant differences were found between intensively used diving areas and unused diving areas in terms of fish abundance, coral cover and macroalgae cover. Despite this, the PFMPA is not currently providing the full set of benefits to humans and the rest of nature, due mainly to administrative issues. If the PFMPA eventually becomes a National Marine Park (i.e. is fully protected from extractive activities), and management is correctly implemented, an annual economic value of almost USD $127,164,116.37 is forecast. At present the PFMPA does not provide any social or economic benefit to the nearby coastal community of Cocodrilo, thereby maintaining a divorce between local people and the users and managers of the MPA. Conversely, foreigners are receiving most of the benefits associated with recreation in a pristine tropical coastal ecosystem situated on the edge of the Caribbean Sea basin. The interdisciplinary methodologies for assessing effectiveness of MPAs developed in this study provided quantitative and qualitative evidence of a poor level of success in meeting the multiple management objectives of the PFMPA. This situation is apparently the result of several factors, both objective and subjective, especially the restrictive nature of the PFMPA relative to local inhabitants. 268 Aronson RB, Precht WF (2000) Herbivory and algal dynamics on the coral reef at Discovery Bay, Jamaica.

    Description: Here we present a new, pan-Atlantic compilation and analysis of data on Calanus finmarchicus abundance, demography, dormancy, egg production and mortality in relation to basin-scale patterns of temperature, phytoplankton biomass, circulation and other environmental characteristics in the context of understanding factors determining the distribution and abundance of C. finmarchicus across its North Atlantic habitat. A number of themes emerge: (1) the south-to-north transport of plankton in the northeast Atlantic contrasts with north-to-south transport in the western North Atlantic, which has implications for understanding population responses of C. finmarchicus to climate forcing, (2) recruitment to the youngest copepodite stages occurs during or just after the phytoplankton bloom in the east whereas it occurs after the bloom at many western sites, with up to 3.5 months difference in recruitment timing, (3) the deep basin and gyre of the southern Norwegian Sea is the centre of production and overwintering of C. finmarchicus, upon which the surrounding waters depend, whereas, in the Labrador/Irminger Seas production mainly occurs along the margins, such that the deep basins serve as collection areas and refugia for the overwintering populations, rather than as centres of production, (4) the western North Atlantic marginal seas have an important role in sustaining high C. finmarchicus abundance on the nearby coastal shelves, (5) differences in mean temperature and chlorophyll concentration between the western and eastern North Atlantic are reflected in regional differences in female body size and egg production, (6) regional differences in functional responses of egg production rate may reflect genetic differences between western and eastern populations, (7) dormancy duration is generally shorter in the deep waters adjacent to the lower latitude western North Atlantic shelves than in the east, (8) there are differences in stage-specific daily mortality rates between eastern and western shelves and basins, but the survival trajectories for cohort development from CI to CV are similar, and (9) early life stage survival is much lower in regions where C. finmarchicus is found with its congeners, C. glacialis and/or C. hyperboreus. This compilation and analysis provides new knowledge for evaluation and parameterisation of population models of C. finmarchicus and their responses to climate change in the North Atlantic. The strengths and weaknesses of modeling approaches, including a statistical approach based on ecological niche theory and a dynamical approach based on knowledge of spatial population dynamics and life history, are discussed, as well as needs for further research.

    Description: Understanding the distribution and foraging ecology of major consumers within pelagic systems, specifically in relation to physical parameters, can be important for the management of bentho-pelagic systems undergoing rapid change associated with global climate change and other anthropogenic disturbances such as fishing (i.e., the Antarctic Peninsula and Scotia Sea). We tracked 11 adult male southern elephant seals (Mirounga leonina), during their five-month post-moult foraging migrations from King George Island (Isla 25 de Mayo), northern Antarctic Peninsula, using tags capable of recording and transmitting behavioural data and in situ temperature and salinity data. Seals foraged mostly within the Weddell–Scotia Confluence, while a few foraged along the western Antarctic Peninsula shelf of the Bellingshausen Sea. Mixed model outputs suggest that the at-sea behaviour of seals was associated with a number of environmental parameters, especially seafloor depth, sea-ice concentrations and the temperature structure of the water column. Seals increased dive bottom times and travelled at slower speeds in shallower areas and areas with increased sea-ice concentrations. Changes in dive depth and durations, as well as relative amount of time spent during the bottom phases of dives, were observed in relation to differences in overall temperature gradient, likely as a response to vertical changes in prey distribution associated with temperature stratification in the water column. Our results illustrate the likely complex influences of bathymetry, hydrography and sea ice on the behaviour of male southern elephant seals in a changing environment and highlight the need for region-specific approaches to studying environmental influences on behaviour.
