Ancient DNA Reveals Late Pleistocene Existence of Ostriches in Indian Sub-Continent.

PLoS ONE, 2017
Ancient DNA (aDNA) analysis of extinct ratite species is of considerable interest as it provides important insights into their origin, evolution, paleogeographical distribution and vicariant speciation in congruence with continental drift theory. In this

An attempt to revisit the global biogeography of limno-terrestrial Tardigrada

Journal of Limnology, 2007
The major increase in distribution records of limno-terrestrial tardigrades over the last ten years has enabled us to reassess the global biogeography of the Tardigrada using cluster analysis, principal components analysis and parsimony analysis of ...

Seismic characteristics of sediment drifts: An example from the Agulhas Plateau, southwest Indian Ocean [PDF]

, 2001
Sediment drifts provide information on the palaeoceanographic development of a region. Additionally, they may represent hydrocarbon reservoirs. Because of this, sediment drift investigation has increased over the last few years. Nevertheless, a number of

Horizontal transport on the continental shelf driven by periodic rotary wind stress [PDF]

Ocean Science
Wind driven circulation of a uniform density fluid on a linearly sloping continental shelf is studied by employing the Lagrangian equations of motion forced by periodic rotary wind stress.

Evidence of Abrupt Transitions Between Sea Ice Dynamical Regimes in the East Greenland Marginal Ice Zone

Geophysical Research Letters, 2023
Sea ice modulates the energy exchange between the atmosphere and the ocean through its kinematics. Marginal ice zone (MIZ) dynamics are complex and are not well resolved in routine observations.

Evidence for a mid-Pleistocene change of ice-drift pattern in the Nordic seas [PDF]

, 2003
Sediment proxy records from a continuous, 1.5 million year long deep-sea sediment core from a site in the western Norwegian Sea were used to obtain new insights into the nature of palaeoceanographic change in the northern North Atlantic (Nordic seas ...

A geomorphological overview of glacial landforms on the Icelandic continental shelf [PDF]

, 2009
The availability of a bathymetric database that covers about 80% of the Icelandic shelf has made it possible to produce a geomorphological map of the glacial landforms.

The beginnings of geography teaching and research in the University of Glasgow: the impact of J.W. Gregory [PDF]

, 2009
J.W. Gregory arrived in Glasgow from Melbourne in 1904 to take up the post of foundation Professor of Geology in the University of Glasgow. Soon after his arrival in Glasgow he began to push for the setting up of teaching in Geography in Glasgow, which ...
