Inverse vertical migration and feeding in glacier lanternfish (Benthosema glaciale)
A bottom-mounted upward-facing 38-kHz echo sounder was deployed at ~400 m and cabled to shore in Masfjorden (~60°52'N, ~5°24'E), Norway. The scattering layers seen during autumn (September-October) 2008 were identified by trawling. Glacier lanternfish (Benthosema glaciale) were mainly distributed below ~200 m and displayed three different diel behavioral strategies: normal diel vertical migrati...
متن کاملSeasonal variations in vertical migration of glacier lanternfish, Benthosema glaciale
The seasonal variations in glacier lanternfish (Benthosema glaciale) vertical distribution and diel vertical migration (DVM) were studied by use of a bottom-mounted upward-facing 38 kHz echo sounder deployed at 392 m depth and cabled to shore in Masfjorden (~60°52'N, ~5°24'E), Norway. Acoustic data from July 2007-October 2008 were analyzed, and scattering layers below ~220 m during daytime were...
متن کاملCytotoxic oleanane-type triterpenoid saponins from the Rhizomes of Anemone rivularis var. flore-minore.
Phytochemical investigation of the n-BuOH extract of the rhizomes of Anemone rivularis var. flore-minore led to the isolation of five new oleanane-type triterpenoid saponins 1-5, together with five known saponins 6-10. Their structures were determined by the extensive use of 1D and 2D NMR experiments, along with ESIMS analyses and acid hydrolysis. The aglycone of 4 and 5 was determined as 21α-h...
متن کاملCaractérisation de la flore bactérienne des péritonites communautaires opérées au Burkina Faso
Introduction: La péritonite communautaire est une urgence chirurgicale récurrente chez l'adulte qui constitue une préoccupation majeure pour le chirurgien et l'anesthésiste-réanimateur dans sa prise en charge. L'objectif de cette étude était d'établir non seulement le profil bactériologique des péritoniques communautaires opérées dans le service de chirurgie générale et digestive du CHU-YO mais...
متن کاملImpact of high CO2 on the geochemistry of the coralline algae Lithothamnion glaciale
Coralline algae are a significant component of the benthic ecosystem. Their ability to withstand physical stresses in high energy environments relies on their skeletal structure which is composed of high Mg-calcite. High Mg-calcite is, however, the most soluble form of calcium carbonate and therefore potentially vulnerable to the change in carbonate chemistry resulting from the absorption of an...
