In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch.
A relic border is a former boundary, which may no longer be a legal boundary at all. However, the former presence of the boundary can still be seen in the landscape. For instance, the boundary between East and West Germany is no longer an international boundary, but it can still be seen because of historical markers on the landscape; it remains ...
In the Spanish-speaking world, a neighborhood or community within a larger urban area, generally with informal boundaries, though in some places the term may refer to a formal subdivision of a municipality. barrow See tumulus. barysphere The Earth's core and mantle considered together, i.e. all of the Earth's interior beneath the lithosphere ...
The boundary between Asia and Europe is unusual among continental boundaries because of its largely mountain-and-river-based characteristics north and east of the Black Sea. Asia and Europe are considered separate continents for historical reasons; the division between the two goes back to the early Greek geographers .
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
The boundaries of a few Anglo-Saxon estates were described in the boundary clauses of Anglo-Saxon Charters. These boundary clauses can sometimes be used to characterise the landscape at the time. In some cases, it has been possible to show that the boundaries of these Anglo-Saxon estates correspond to the boundaries of the subsequent parish.
[2] Advancements in molecular biology and theory of evolution within zoological research has unraveled questions concerning speciation events and has expanded phylogenic relationships amongst taxa. [3] Integration of phylogenetics with GIS provides a means for communicating evolutionary origins through cartographic design.
Metes and bounds is a system or method of describing land, real property (in contrast to personal property) or real estate. [1] The system has been used in England for many centuries and is still used there in the definition of general boundaries.
