Species Groups

Recurrent species groups were formed by computer analysis from the data on occurrence of demersal fish at 480 trawl stations in the tropical eastern Atlantic; these recurrent groups were then marshalled into a small number of major species assemblages, or communities in the wide sense, on the basis of intergroup relationships. These assemblages proved to be remarkably similar in composition and ecology to the communities of demersal fish recognized earlier by a number of authors from their subjective analysis of trawling survey data in this region. The computer analysis provided finer detail on both the structure and distribution of the assemblages and their constituent groups. This confirmation of the reality of the subjectively recognized communities suggests (1) that the recognition of such assemblages by subjective methods has a place in the assessment of multispecies fish resources but (2) that where the method is practicable, the machine processing of recurrent species groups in the analysis of trawl survey data can be a valuable tool in resource evaluation.

The aim of this paper was to relate anopheline mosquito longevity to malaria incidence in two areas in Indonesia: West Timor and Central Java. We estimated the physiological age of females captured landing on humans or resting inside and outside buildings. The estimate was based on the state of the ovaries and was used to estimate longevity. The results showed that there were large differences between the two areas surveyed. In West Timor the longevity of the anophelines ranged from 13 to 23 days, sufficient for completing the intrinsic incubation cycle and for malaria transmission, whereas in Central Java the longevity was only 3 days, insufficient both for incubation and for transmission. We concluded that the West Timor study area had a greater risk of malaria transmission than that of Central Java and this was supported by village survey data that showed greater malaria incidence in West Timor than in Central Java.

Political Decision Making

Citizens increasingly engage with political issues in new ways by addressing politicians via social media, campaigning at international forums, or boycotting corporate entities. These forms of engagement move beyond more regulated electoral politics and are rightly celebrated for the ways they increase representation and provide new channels of accountability. Yet, despite these virtues, political engagement beyond voting inevitably tends to entrench and amplify inequality in citizen influence on political decision-making. The tendency toward inequality undermines relational equality between citizens and muddies the channels of political accountability and responsibility. This article unpacks the ostensible tension and argues that it reveals to us another strength in views which hold the state to be citizens’ collective project and provides argumentative resources to motivate democracies to give due attention to ensuring that democratic participatory channels remain fit for purpose in an ever-changing society.

Abstract Fraser, H. M., Greenstreet, S. P. R., and Piet, G. J. 2009. Selecting MPAs to conserve groundfish biodiversity: the consequences of failing to account for catchability in survey trawls. – ICES Journal of Marine Science, 66: 82–89. Fishing has affected North Sea groundfish species diversity. Defining Marine Protected Areas (MPAs) to address this will rely on groundfish surveys. Species-specific catch efficiencies vary between trawl gears, and apparent species diversity distributions are influenced by the type of gear used in each survey. It may be that no single survey depicts actual diversity distributions. Two MPA scenarios designed to protect groundfish species diversity are described, the first based on unadjusted International Bottom Trawl Survey data and the second based on the same data adjusted to take account of catchability. Spatial overlap between these scenarios is low. Assuming that the adjusted data best describe the actual species diversity distribution, the level of diversity safeguarded by MPAs, based on unadjusted data, is determined. A fishing effort redistribution model is used to estimate the increase in fishing activity that is likely to occur in MPAs that take catchability into account, if closed areas based solely on the unadjusted groundfish data were implemented. Our results highlight the need to take survey-gear catchability into account when designating MPAs to address fish-species diversity issues.

There is now a large literature on ecosystem-based management (EBM; also known as the ecosystem approach). Our sense is that EBM is moving - albeit slowly - from the “what's, why's and when's” to the “how's” of operationalization and implementation; as such it seemed timely to develop this article theme set (TS). Our objectives were to ascertain the state of the discipline and to advance EBM by offering practical examples of its implementation - or attempts at such - in a variety of incarnations and at various scales, including what has or has not worked, suggestions for best practice, and lessons learned. As exemplified by the articles in this TS, key lessons learned include the need for: constant and clear communication with all parties involved; clear objectives and governance; the distillation of complex ecosystem information into digestible indicators; the establishment of reference levels on which management decisions can be made; and clear protocols to evaluate tradeoffs. Instances of truly multisectoral EBM remain rare, with EBM having advanced farthest within specific ocean-use sectors. Although progress towards implementing operational EBM has been somewhat limited, and although EBM is by its very nature complex and difficult to operationalize, there has been progress nonetheless. We hope that this TS will encourage even further operationalization of EBM.
