    Contributor(s):: Thomas, J. R., James, J., Newman, R. C., Riley, W. D., Griffiths, S. W., Cable, J.

    Artificial light at night (ALAN) can significantly alter the behaviour, communication and orientation of animals, and will potentially interact with other stressors to affect biodiversity. Invasive, non-native species are one of the largest threats to freshwater biodiversity; however, the impact...

  6. Does environmental enrichment promote recovery from stress in rainbow trout?

    Contributor(s):: Pounder, K. C., Mitchell, J. L., Thomson, J. S., Pottinger, T. G., Buckley, J., Sneddon, L. U.

    The EU Directive on animal experimentation suggests that all protected animals should have enrichment to improve welfare yet relatively little research has been conducted on the impact of enrichment in fish. Studies employing enrichment in zebrafish have been contradictory and all fish species...

  7. Determining the effects of duration and recency of exposure to environmental enrichment

    Contributor(s):: Bergendahl, I. A., Salvanes, A. G. V., Braithwaite, V. A.

    Experience can help animals adapt their behaviour to fit the environment or conditions that they find themselves in. Understanding how and when experience affects behaviour is important for the animals we rear in captivity. This is particularly true when we rear animals with the intent of...

  8. Bioaccumulation of mercury in Wilson's snipe from Alabama

    Contributor(s):: Brooks, Lindsay J., Campbell, Joshua W., Murphy, Julie W.

  9. Re-Homing Exotic Species - A Pilot Program to Prevent Release of Exotic Aquatic Pet Species

    Contributor(s):: Andrew M. Lazur, Ruth Hanessian

    An educational poster program designed to inform pet owners of the dangers of releasing exotic species and provide a re-homing mechanism was evaluated as a means to reduce unwanted environmental releases. The poster provided a URL to the program partners' Web site, which listed participating...

  10. Activity budgets of captive Cape fur seals ( Arctocephalus pusillus) under a training regime

    Contributor(s):: Wierucka, K., Siemianowska, S., Wozniak, M., Jasnosz, K., Kieliszczyk, M., Kozak, P., Sergiel, A.

    Ethograms and time budgets are crucial for the behavioral assessment of nonhuman animals in zoos, and they serve as references for welfare research. This study was conducted to obtain detailed time budgets of trained Cape fur seals ( Arctocephalus pusillus) in captivity, to evaluate variations of...

  11. Why did the fish cross the tank? Objectively measuring the value of enrichment for captive fish

    Contributor(s):: Sullivan, M., Lawrence, C., Blache, D.

    There has been very little research into the enrichment preferences of ornamental fish, even though there are billions of fish kept in captivity as pets and research animals. We used preference and motivational testing to compare the value of real and artificial plants to goldfish ( n=20,...

  12. Des exploitations intensives d'huitres pendant l'Antiquite et le Moyen Age sur le littoral atlantique francais: l'exemple de Beauvoir-sur-Mer (Vendee)

    Contributor(s):: Dupont, C., Rouzeau, N.

    Along the European Atlantic facade, the consumption of flat oysters (Ostrea edulis Linnaeus, 1758) has been known since the Mesolithic era (Gutierrez-Zugasti et al. 2011). This observation is also true for French coasts (Dupont 2006). Especially during Antiquity, the exploitation of this species...

  13. Intensive exploitation of oysters during Antiquity and the Middle Ages on the French Atlantic coast: the example of Beauvoir-sur-Mer (Vendee)Des exploitations intensives d'huitres pendant l'Antiquite et le Moyen Age sur le littoral atlantique francai
