Continental aquatic species richness hotspots are unevenly distributed across the planet. In present-day Europe, only two centers of biodiversity exist (Lake Ohrid on the Balkans and the Caspian Sea). During the Neogene, a wide variety of hotspots developed in a series of long-lived lakes. The mechanisms underlying the presence of richness hotspots in different geological periods have not been ...

Immunological comparisons of a larval hemolymph protein enabled us to build a tree relating major groups of drosophiline flies in Hawaii to one another and to continental flies. The tree agrees in topology with that based on internal anatomy. Relative rate tests suggest that evolution of hemolymph proteins has been about as fast in Hawaii as on continents. Since the absolute rate of evolution o...

This article provides a concise overview of the history of scholarship on solidarity in Europe and North America. While recent decades have seen an increase in conceptual and scholarly interest in solidarity in North America and other parts of the Anglo-Saxon world, the concept is much more strongly anchored in Europe. Continental European politics in particular have given rise to two of the mo...

Peat layers 2 to 30 cm in thickness, 22 to 46 m below present sea level, are found along the inner shelf of India, up to 27 km from the coast. They are rich in plant debris, organic carbon and sulfur. These organic-rich layers are not sedimentary deposits. Lack of favourable substrates, absence of sheltered habitats, high energy physical enVironments, and a very rapid sea level rise during earl...

A variety of geophysical data indicates that long wavelength temperature variations of the asthenosphere depart from the mean by + 200øC, not the + 20øC adopted by plume theoreticians. The 'normal' variation, caused by plate tectonic processes (subduction cooling, continental insulation, smallscale convection) encompasses the temperature excesses that have been attributed to hot jets and therma...

Divergent flow of the West Antarctic Ice Sheet on the outer continental shelf of the Amundsen Sea during the late Quaternary" (2007). Related Publications from ANDRILL Affiliates. Paper 7. Summary Understanding the past glacial history of regions undergoing potential rapid deglaciation is essential in order to estimate the possible threat of sea level rise. Recently acquired data have given new...

Inversion of NASA Operation IceBridge airborne gravity over the Abbot Ice Shelf in West Antarctica for subice bathymetry defines an extensional terrain made up of east-west trending rift basins formed during the early stages of Antarctica/Zealandia rifting. Extension is minor, as rifting jumped north of Thurston Island early in the rifting process. The Amundsen Sea Embayment continental shelf w...
