Comparative depth distribution of corallimorpharians and scleractinians (Cnidaria: Anthozoa)
We assessed whether CaCO3 concentration of seawater may be relevant to the occurrence of members of Corallimorpharia and Scleractinia, which are very similar except for the possession by scleractinians of a calcareous skeleton. In collections of both the Challenger Deep-sea Expedition 1872–1876 and the US Antarctic (Research) Program, average depth of occurrence was significantly greater for co...

متن کاملFine structure of hyperbolic
The main theme of the book Fine Structures of Hyperbolic Diffeomorphisms, by Pinto, Rand and Ferreira, is the rigidity and flexibility of two-dimensional diffeomorphisms on hyperbolic basic sets and properties of invariant measures that are related to the geometry of these invariant sets. In his remarkable article [23], Smale sets the foundations of the modern theory of dynamical systems. He de...
متن کاملFine Structure of Helium
Under the expectation that experiments will soon give values for the 6ne structure intervals of the 2'I" state of helium to an accuracy of 1/10', we have undertaken a program of calculations which, it is hoped, will lead to a new determination of the 6ne-structure constant n. This paper gives a brief survey of the over-all program, and a detailed report of the successful completion of the', 6rs...
متن کاملFine Structure of Mycota
Though the dictyosome of the Golgi apparatus appears to be generally distributed in plant and animal cells, it is here described for the first time in the fungi. The present report illustrates, in electron micrographs of thin sections, the characteristic structure of the Golgi dictyosome in a special cell type of a supporting pseudo-tissue (the inner ectal excipulum) of a highly evolved Ascomyc...
