The Polychaetous Annelids of Alaska
THIS PAPER is based on the polychaetous annelids obtained by the Alaska King Crab Investigation, which was sponsored by the United States Fisheries Commission. The annelids were taken almost entirely from southern and southwestern Alaska, from Port Ashton west to the western end of the Alaska Peninsula (Map I). In addition, some were obtained from scattered stations eastward to Icy Straits, nea...
متن کاملAdrenalin in Annelids
1. The sympathetic nervous system and the adjuvant adrenalin-secreting system are found in their earliest form in the annelid kingdom, and consist of cells situated in the central nervous system which are the common ancestors of both, and which are both secretory and nervous in function. 2. These cells are developed in the annelid kingdom parallel with the development of a contractile vascular ...
متن کاملUndulatory locomotion of polychaete annelids:
The undulatory locomotion of polychaete annelid worms is studied as a biological paradigm of a versatile body morphology and effective motion control, adaptable to a large variety of unstructured and tortuous environmental conditions (water, sand, mud, sediment, etc.). Computational models of this type of locomotion have been developed, based on the Lagrangian dynamics of the system, on resisti...
متن کاملPassive ventilation in benthic annelids?
NdCoO3, and LaCoO3, are strikingly similar to each other and to RCo03 where R (6) is the natural rare earth mixture as mined. We suggest, therefore, that the unseparated rare earth oxides can be used to make a cheap auto exhaust oxidation catalyst. LEE A. PEDERSEN W. F.

متن کاملOut of Asia: mitochondrial evolutionary history of the globally introduced supralittoral isopod Ligia exotica
The native ranges and invasion histories of many marine species remain elusive due to a dynamic dispersal process via marine vessels. Molecular markers can aid in identification of native ranges and elucidation of the introduction and establishment process. The supralittoral isopod Ligia exotica has a wide tropical and subtropical distribution, frequently found in harbors and ports around the g...
