More recently these same acoustic sensors were placed on a simulated buoy in an attempt to detect and track aircraft over a large body of water. This report will investigate the advantages of using acoustic arrays to track air and water craft from a fixed floating platform as well as potential concerns associated with this technology. Continuous monitoring of aircraft overflight will increase situational awareness while persistent monitoring of commercial and military flight paths increases overall homeland security.10aacoustics10aamibio10aasr10amonitoring1 aSolomon, Latasha1 aSim, Leng1 aTenney, Stephen1 aCarapezza, Edward, M.  uhttp://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=PSISDG00694300000169430Z000001&idtype=cvips&gifs=yes02317nas a2200205   4500008004100000022001400041245013500055210006900190260001300259300001400272490000700286520165500293653001701948653002101965653001501986653001102001100002402012700002702036856004802063       2008                        eng d  a0167-454400aPrinciples and Influence in Codes of Ethics: A Centering Resonance Analysis Comparing Pre- and Post-Sarbanes-Oxley Codes of Ethics0 aPrinciples and Influence in Codes of Ethics A Centering Resonanc  cDecember  a263–2780 v803 aAbstract&nbsp;&nbsp;Halting the loss of biodiversity comes along with the need to quantify biodiversity composition and dynamics at large spatial and temporal scales. Highly standardized, international monitoring networks would be ideal, but they do not exist yet. If we are to assess changes in biodiversity now, combining output available from ongoing monitoring initiatives is the only option. However, integration of biodiversity information across schemes is still very poorly developed. In this paper, we outline practical issues to be considered when planning to combine existing monitoring information. First, we provide an overview of avenues for integration along the four dimensions that characterize a monitoring design: sample size, biological coverage, spatial coverage and temporal coverage. We also emphasize that complementarity in monitoring targets across schemes enables to describe complex processes of biodiversity dynamics, e.g. through relating species traits to the impacts of environmental changes. Second, we review some methods to overcome differences in designs among monitoring schemes, such as site selection, post-stratification and measurement error. Finally, we point out some commonly used statistical methods that are at hand for combining data or parameter estimates. We especially emphasize the possible levels of data integration (raw data, parameter estimates, or effect size estimates), and the largely under-exploited potential of meta-analysis methods and weighted analyses. This contribution aims to bolster the practice and use of integration of ongoing monitoring initiatives for biodiversity assessment.10abiodiversity10adata-integration10amonitoring10areview1 aCanary, Heather, E.1 aJennings, Marianne, M.  uhttp://dx.doi.org/10.1007/s10531-008-9417-101806nas a2200169   4500008004100000245006300041210006100104260001300165300001600178490000700194520132300201653001701524653001201541653001501553100002001568856004801588       2008                        eng d00aEuropean species and habitat monitoring: where are we now?0 aEuropean species and habitat monitoring where are we now  cDecember  a3321–33260 v173 aAbstract&nbsp;&nbsp;Biodiversity now is considered a highly valuable material, providing manifold services of high importance for the well-being of humankind. However, biodiversity globally is rapidly diminishing and, despite efforts to halt the loss of biodiversity, positive effects are hardly visible. Biodiversity monitoring, the close observation of our natural environment, is imperative to determine the state and trend of organism populations and their habitats. Therefore, it has become a centrepiece of nature conservation across the globe. However, monitoring activities are not centrally coordinated, differ vastly in their monitoring targets, sampling designs, and human resource needs. This special issue on biodiversity and monitoring presents an overview of the current state of biodiversity monitoring in Europe, gives suggestions for the integration of monitoring data to improve the geographical and taxonomic coverage, deals with general methodological aspects of monitoring biodiversity across different geographic scales, the involvement of the public in monitoring activities, and provides some monitoring case studies. The special issue is aimed to provide recommendations and suggestions for more standardized monitoring approaches, and is mainly based on the findings of the EU-project EuMon.10abiodiversity10amethods10amonitoring1 aSchmeller, Dirk  uhttp://dx.doi.org/10.1007/s10531-008-9514-1
