Preglacial

As a result of their isolation, most of the native plant species on the Azores are living fossils, phylogenetically primitive, and related to, though divergent from, the preglacial flora of Europe. ❋ Unknown (2008)

The ridges of Ecoregion 70f are forested while its floodplains and broad, clay-filled, flat-bottomed, preglacial valleys are used for general farms. ❋ Unknown (2008)

Like other isolated islands, the Azores have functioned as a natural evolutionary laboratory - most of the native plant species are living fossils, phylogenetically primitive, and related to, though divergent from, the preglacial flora of Europe. ❋ Unknown (2008)

The Darby Plains ecoregion once had a distinct assemblage of mixed oak forest; many prairies occurred on its end moraines, gravel-filled preglacial valleys, and seasonally wet areas. ❋ Unknown (2008)

The Mad River Interlobate Area ecoregion is flanked by end moraines and received concentrated outwash deposits that filled preglacial valleys. ❋ Unknown (2008)

This appears to be the preglacial mouth of the Huron River. ❋ Unknown (2007)

Efficient organic carbon burial sustained over tens of millions of years, required by the high carbon isotopic compositions of preglacial carbonate, may lead to the buildup of enormous quantities of methane, presumably in hydrate reservoirs. ❋ Unknown (2007)

It was via this Atlantic Ocean route that, in preglacial times, the ancestor of the subspecies oquassa probably reached North America. ❋ Robert J. Behnke (2002)

Atlantic salmon are similar to Pacific salmon in that they left no glacial or preglacial “relict” populations outside of the range of sea-run populations. ❋ Robert J. Behnke (2002)

Subspecies are assumed to classify geographically distinctive groups that are derived from preglacial branchings that became isolated in different glacial refugia. ❋ Robert J. Behnke (2002)

But as these landscapes have succeeded the preglacial landscapes, so they in turn are giving place to others already planned and foreseen. ❋ Unknown (1969)
