چکیده
Abstract The living and dead fauna of Valencia Seamount, a deep promontory in the middle Balearic Basin which summit is at ca. 1100 m depth, described by first time based rock dredge perfomed sedimentary area Mount. Surface-feeder polychaetes (the Paraonidae Levinsenia gracilis Terebellidae as dominant), taxodont bivalves ( Ledella messanensis Yoldiella ovulum ) were main species benthos. We found alive remains bamboo coral Isidella elongata , vulnerable, habitat-forming Mediterranean. Benthos density was low (0.6 organisms/2 dm 3 mud). Thanatocoenosis evidenced rather moderate diversity benthic (11 species) gastropods (9 also dominated surface deposit feeders. Fish (identified/quantified from sedimented otoliths) showed diversified abundant mesopelagic fauna, mainly Myctophidae. More interestingly, we highlighted among benthopelagic fish occurrence recruits Merluccius merluccius Micromesistius poutassou or Hymenocephalus italicus all that live neighboring slopes Iberian Peninsula Islands quite shallower depths (at 100-700 m) than their distribution Seamount (1102–1130 on deposited otoliths found. Some ecological aspects discussed necessity to consider potential should be under protection.

Some Considerations regarding the Ecological Sustainability of Marketing Systems
Sustainable development is perhaps the most significant and yet the most difficult problem that marketing – and human economic activity in general – face at the beginning of the third millennium. The paper starts by charting the state of affairs for marketing and sustainability so far. It then uses the analogy of a living system to explore the requirements for a sustainable marketing system and...
متن کاملSome Considerations on Universality
Without the investigation of the concept of universality it is quite possible that our modern computers wouldn’t exist. Although they are finite automata, at least theoretically, practically they can be treated as Turing machines processing any special program which can be seen as a special Turing machine. This paper presents some general considerations on that concept, presenting in some more ...
