SUMMARY: Planktonic larvae were captured above a shallow coral reef study site on the Great Barrier Reef (GBR) around spring-summer new moon periods (October-February) using light trap or net capture devices. Larvae were identified to the genus or species level by comparison with a phylogenetic tree of tropical marine fish species using mtDNA HVR1 sequence data. Further analysis showed that within-species HVR1 sequence variation was typically 1-3%, whereas between-species variation for the same genus ranged up to 50%, supporting the suitability of HVR1 for species identification. Given the current worldwide interest in DNA barcoding and species identification using an alternative mtDNA gene marker (cox1), we also explored the efficacy of different primer sets for amplification of cox1 in reef fish, and its suitability for species identification. Of those tested, the Fish-F1 and -R1 primer set recently reported by Ward et al. (2005) -Las larvas estudiadas fueron capturadas en el plancton de una zona coralina somera en la Gran Barrera de Coral en períodos de luna-nueva de la estación primavera-verano (octubre-febrero). Su captura se realizó mediante trampas de luz o redes de plancton. Las larvas fueron identificadas a nivel de género o especie por la comparación de un árbol filogenético de especies de peces tropicales marinas usando datos de la secuencia HVR1 del DNA mitocondrial. El análisis adicional demostró que, para una misma especie, la variación de la secuencia HVR1 era típicamente 1-3%, mientras que entre especies del mismo género la variación fue de hasta 50%, apoyando la conveniencia del uso del HVR1 para la identificación a nivel específico. Dado el interés mundial actual en el "código de barras genético" y en la identificación de especies usando otro marcador genético de DNA mitochondrial, el cox1, se exploró también la eficacia de diversos "primers" para la amplificación del cox1 en peces de los arrecifes, y su conveniencia para la identificación específica. De los "primers" probados, el Fish-F1 y el -R1 set recientemente reportado por Ward et al. (2005) dieron los mejores resultados.Palabras clave: peces de coral, mtDNA, HVR1, cox1, DNA identificación específica por código de barras genético.
When using cephalopods as experimental animals, a number of factors, including morality, quality of information derived from experiments, and public perception, drives the motivation to consider welfare issues. Refinement of methods and techniques is a major step in ensuring protection of cephalopod welfare in both laboratory and field studies. To this end, existing literature that provides details of methods used in the collection, handling, maintenance, and culture of a range of cephalopods is a useful starting point when refining and justifying decisions about animal welfare. This review collates recent literature in which authors have used cephalopods as experimental animals, revealing the extent of use and diversity of cephalopod species and techniques. It also highlights several major issues when considering cephalopod welfare; how little is known about disease in cephalopods and its relationship to senescence and also how to define objective endpoints when animals are stressed or dying as a result of the experiment.
Nautilus species are the only remaining cephalopods with an external shell.

Ahead of any formal proposals to reintroduce White Tailed Sea Eagles to Cumbria, UK, 23 We conducted a baseline public attitudinal survey (n=300). We identified broad public support for 24 this reintroduction, which transcended differences in the demographic, geographic and 25 -1 -employment profiles of the study cohort. There was public recognition that White- Tailed Sea 26 Eagles could deliver a broad range of socio-economic and environmental benefits with few 27 detrimental impacts. Whilst the value of attitudinal surveys of this nature has been questioned, 28 we would argue that they provide a useful baseline 'snapshot' ahead of a more structured and 29 focused reintroduction consultation. These results reinforce the emergence of public interest in 30 the restoration of European raptors in the late twentieth and early twenty first century. 32Key words: Cumbria, England, public attitude, raptor, reintroduction, White-Tailed Sea Eagle.
