    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: 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: The biodiversity of aquatic inland habitats currently faces unprecedented threats from human activities. At the same time, although much is known about the functioning of freshwater ecosystems the successful transfer of such knowledge to practical conservation has not been universal. Global awareness of aquatic conservation issues is also hampered by the fact that conditions under the water surface are largely hidden from the direct experience of most members of society. Connectivity, or lack of it, is another challenge to the conservation of freshwater habitats, while urban areas can play a perhaps unexpectedly important positive role. Freshwater habitats frequently enjoy benefits accruing from a sense of ownership or stewardship by local inhabitants, which has led to the development of conservation movements which commonly started life centred on the aquatic inland habitat itself but of which many have now matured into wider catchment-based conservation programmes. A demonstrable need for evidence-based conservation management in turn requires scientific assessments to be increasingly robust and standardised, while at the same time remaining open to the adoption of technological advances and welcoming the rapidly developing citizen science movement. There is evidence of real progress in this context and conservation scientists are now communicating their findings to environmental managers in a way and on a scale that was rarely seen a couple of decades ago. It is only in this way that scientific knowledge can be efficiently transferred to conservation planning, prioritisation and ultimately management in an increasingly scaled-up, joined-up and resource-limited world. The principle of ‘prevention is better than cure’ is particularly appropriate to most biological conservation issues in aquatic inland habitats and is inextricably linked to educating and/or nudging appropriate human behaviours. When prevention fails, some form of emergency rescue such as captive breeding or translocations may be justified for particularly important animal or plant populations. However, long-haul missions of habitat rehabilitation or restoration are generally to be preferred even if they usually take many years if not decades to reach fruition. Conservation researchers, managers and practitioners must be realistic in their objectives and timescales for such programmes and take positive steps to communicate such information to stakeholders. Now more than ever, people are interested in conservation and sustainability. There are substantial challenges ahead, but these are better days for the biological conservation of aquatic inland habitats.
