Betula populifolia, known as the gray (or grey) birch, is a deciduous tree in the family Betulaceae. It is native to eastern North America and is most commonly found in the northeast United States as well as southern Quebec , New Brunswick , and Nova Scotia . [ 1 ]
Aethalura punctulata, the grey birch, is a moth of the family Geometridae. The species is found in Europe and then east, as far as western Siberia and the Caucasus.This species prefers sparse alder-ash-floodplain forests on moist to wet locations. Although it is only locally distributed in Central Europe, it is usually common in these biotopes.
A list of tree species, grouped generally by biogeographic realm and specifically by bioregions, and shade tolerance. Shade-tolerant species are species that are able to thrive in the shade, and in the presence of natural competition by other plants.

The tree of life image that appeared in Darwin's On the Origin of Species, 1859; Early classification chart are often visualized in a tree structure. Modern charts can also be presented in table or as an infographic. The term "classification chart" came into use in the 20th century. In his 1939 Graphic presentation.
Edward Hitchcock's fold-out paleontological chart in his 1840 Elementary Geology. Although tree-like diagrams have long been used to organise knowledge, and although branching diagrams known as claves ("keys") were omnipresent in eighteenth-century natural history, it appears that the earliest tree diagram of natural order was the 1801 "Arbre botanique" (Botanical Tree) of the French ...
The Betulaceae are believed to have originated at the end of the Cretaceous period (about 70 million years ago) in central China.This region at the time would have had a Mediterranean climate due to the proximity of the Tethys Sea, which covered parts of present-day Tibet and Xinjiang into the early Tertiary period.
For example, a molecule can be viewed as a grouping of elements, and an atom can be further divided into subatomic particles (these levels are outside the scope of biological organisation). Each level can also be broken down into its own hierarchy, and specific types of these biological objects can have their own hierarchical scheme.
