The biology and philosophy of adaptation
A logico-linguistic analysis is presented first, in which the symbolization of being adapted, having an adaptation, and having adaptedness is explained. Next the linguistic-realistic divide is portrayed. This is explained ...
The application of set theory to ecology
Sets and membership are part of the structure of the world. Sets and membership hold nature together.
Evolution of the Southwest Indian Ridge from 55°45′E to 62°E : changes in plate-boundary geometry since 26 Ma
(American Geophysical Union, 2007-06-23)
From 55°45′E to 58°45′E and from 60°30′E to 62°00′E, the ultraslow-spreading Southwest Indian Ridge (SWIR) consists of magmatic spreading segments separated by oblique amagmatic spreading segments, transform faults, and ...
An unusual suctorial montacutid bivalve from the deep Atlantic
(Cambridge University Press, 2000-10-31)
The shell and internal anatomy of the montacutid bivalve Mysella verrilli is described for the first time. The species is remarkable in that the oesophagus has developed into a suctorial proboscis. This has been accompanied ...
Sedimentary evidence of hurricane strikes in western Long Island, New York
(American Geophysical Union, 2007-06-21)
Evidence of historical landfalling hurricanes and prehistoric storms has been recovered from backbarrier environments in the New York City area. Overwash deposits correlate with landfalls of the most intense documented ...
Sea surface temperature signatures of oceanic internal waves in low winds
(American Geophysical Union, 2007-06-20)
In aerial surveys conducted during the Tropical Ocean–Global Atmosphere Coupled Ocean-Atmosphere Response Experiment and the low-wind component of the Coupled Boundary Layer Air-Sea Transfer (CBLAST-Low) oceanographic field ...
Characterization of methyl sugars, 3-deoxysugars and methyl deoxysugars in marine high molecular weight dissolved organic matter
Nuclear magnetic resonance spectroscopy of marine high molecular weight dissolved organic matter (HMWDOM) in surface waters show that >50% of the carbon is a compositionally well-defined family of acylated-polysaccharides ...
Tidal and meteorological forcing of sediment transport in tributary mudflat channels
Field observations of flow and sediment transport in a tributary channel through intertidal mudflats indicate that suspended sediment was closely linked to advection and dispersion of a tidal salinity front. During calm ...
Quantitative bedrock geology of the continents and large-scale drainage regions
(American Geophysical Union, 2007-06-13)
We quantitatively analyze the area-age distribution of sedimentary, extrusive volcanic, and endogenous (plutonic and/or metamorphic) bedrock on the basis of data from the most recent digital Geological Map of the World at ...
Quantitative bedrock geology of Brazil
(American Geophysical Union, 2007-05-30)
We quantitatively analyze the area-age distribution of sedimentary, igneous, metamorphic, and ultramafic bedrock on the basis of data from the digital geologic map of Brazil, published as a GIS map by the Brazilian Geological ...
