In terms of biodiversity, the only comparable temperate deciduous forest regions in the world are in central China, Japan, and in the Caucasus Mountains.Both the Appalachians (along with the neighbouring Appalachian mixed mesophytic forests ecoregion) and central China contain relict habitats of an ancient forest that was once widespread over the Northern Hemisphere.
The range is older than the other major mountain range in North America, the Rocky Mountains of the west. Some of the outcrops in the Appalachians contain rocks formed during the Precambrian era. The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago.
The US uses the term Appalachian Highlands, and Canada uses the term Appalachian Uplands, to define contiguous regions that have similar geology, topography, history, and native plant and animal communities. (The Appalachian Mountains are not synonymous with the Appalachian Plateau, which is one of the provinces of the Appalachian Highlands).
Thus relatively little is known about Appalachia in comparison to Laramidia, with the exception of plant life, marine life and the insects trapped in amber from New Jersey. In addition, due to a lack of interest in Appalachia, many fossils that have been found in Appalachia lie unstudied and remain in the inaccurate genera to which they were ...
Edgar Allan Poe later took up the idea and considered Appalachia a much better name than America or Alleghania; he thought it better defined the United States as a distinct geographical entity, separate from the rest of the Americas, and he also thought it did honor to both Irving and the natives after whom the Appalachian Mountains had been ...
He thinks most trees toppled because the soil was so saturated. During the height of the storm, Godfrey said, he heard a pattern ringing throughout the neighborhood as one tree fell after another.
The Appalachian temperate rainforest has a cool and mild climate and meets the criteria of temperate rainforests identified by Alaback. [1] Temperature and precipitation are extremely variable with elevation, with rainforest conditions usually but not always concentrated around spruce–fir forests at higher elevations.
Giant tortoises live on a limited number of tropical islands in the Galápagos Islands and Aldabra Atoll. ... Because he was fully grown, animal experts think Jonathan was 50 years old when he ...
