Benthic Nitrogen Loss in the Arabian Sea Off Pakistan
A pronounced deficit of nitrogen (N) in the oxygen minimum zone (OMZ) of the Arabian Sea suggests the occurrence of heavy N-loss that is commonly attributed to pelagic processes. However, the OMZ water is in direct contact with sediments on three sides of the basin. Contribution from benthic N-loss to the total N-loss in the Arabian Sea remains largely unassessed. In October 2007, we sampled th...
متن کاملFirst confirmed reports of the rhizostome jellyfish Mastigias (Cnidaria: Rhizostomeae) in the Atlantic basin
The rhizostome jellyfish Mastigias (Agassiz, 1862), native to the western and central Indo-Pacific, is recorded from the western Atlantic, in a marine lake in Puerto Rico (Laguna Joyuda) and a working quarry on No Name Key, Florida (USA) in the Florida Keys. The single individual from Laguna Joyuda, collected in 2002, was previously misidentified as Phyllorhiza (Agassiz, 1862) and Mastigias has...
متن کاملLack of genetic structure in the jellyfish Pelagia noctiluca (Cnidaria: Scyphozoa: Semaeostomeae) across European seas.
The genetic structure of the holopelagic scyphozoan Pelagia noctiluca was inferred based on the study of 144 adult medusae. The areas of study were five geographic regions in two European seas (Eastern Atlantic and Mediterranean Sea). A 655-bp sequence of mitochondrial cytochrome c oxidase subunit I (COI), and a 645-bp sequence of two nuclear internal transcribed spacers (ITS1 and ITS2) were an...
متن کاملMacro-morphological variation among cryptic species of the moon jellyfish, Aurelia (Cnidaria: Scyphozoa)
Morphological variation in qualitative and quantitative features is compared among species of Aurelia defined a priori using molecular criteria. Macromorphological features were more numerous than previously implied (28 cf. 17), most were variable (26 of 28), and all species were morphologically distinguishable using univariate, multivariate and phylogenetic statistics. However, due to discrepa...
متن کاملMass deposition of jellyfish in the deep Arabian Sea
In December 2002, large numbers of dead jellyfish, Crambionella orsini, were observed on the seabed over a wide area of the Arabian Sea off the coast of Oman at depths between 300 m and 3,300 m. Moribund jellyfish were seen tumbling down the continental slope. Large aggregations of dead jellyfish were evident within canyons and on the continental rise. At the deepest stations, patches of rottin...
