Scarlet Oak
''Quercus coccinea'', the scarlet oak, is a deciduous tree in the red oak section ''Lobatae'' of the genus ''Quercus'', in the family Fagaceae. It is primarily distributed in the central and eastern United States. It occurs on dry, sandy, usually acidic soil. It is often an important canopy species in oak–heath forests. The scarlet oak is the official tree of Washington, D.C. Description ''Quercus coccinea'' is a medium to large deciduous tree growing to around with an open, rounded crown; the maximum height is approximately . The trunk diameter at breast height is typically It is a medium-size tree that grows fast and matures relatively early. It sets a deep growing taproot. The leaves are glossy green, long and broad, with seven lobes, and deep sinuses between the lobes. Each lobe has 3–7 bristle-tipped teeth. The leaf is hairless (unlike the related pin oak (''Q. palustris''), with tufts of pale orange-brown down where the lobe veins join the central vein). The ...

Otto Von Münchhausen
Otto II. Freiherr von Münchhausen (11 June 1716 – 13 July 1774) was a German botanist. He was Chancellor of University of Göttingen and a correspondent of Linnaeus. He named several species of oaks by the Linnean system, as well as other plants. The standard botanical author abbreviation Münchh. is applied to species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ... he described.

Alsophila Pometaria
''Alsophila pometaria'', the fall cankerworm, is a moth of the family Geometridae. The species was first described in English by the KJV Bible oel 1:4 It is found in North America from Nova Scotia west to Alberta, south to Colorado and California and zones of Spain Description The caterpillars grow to about 25 mm long. In color, they vary from light green to a dark brownish green. Light green caterpillars have white lines running down the body from the head to the tip of the abdomen while the darker caterpillars have a black stripe the length of their back. Larvae have three pairs of legs on their thorax and three pairs of prolegs on their abdomen. The first pair of prolegs is much smaller than the last two pairs. The pupa is wrapped in a silk cocoon and is buried just beneath the surface of the ground."Fall Cankerworm" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acleris Semipurpurana
''Acleris semipurpurana'' is a species in the moth family Tortricidae, and one of several species of moth commonly known as oak leaftier or oak leaf tier. The larvae feed on the leaves of oak trees in the Eastern United States and southeastern Canada which can be a major cause of defoliation. The loss of leaves can kill or damage the affected trees, which are chiefly in the ''Lobatae'' or red oak section of '' Quercus'', or oaks. Adult ''Acleris semipurpurana'' moths lay single eggs on oak tree branches in June which develop over winter and hatch the next April. The larvae eat tree buds and young leaves, then tie leaves together with silk (hence the name). They nest and eat inside the tied leaves, then pupate in the leaf litter on the floor in May or June. After a week or two the adult moths emerge, mate, and lay the next generation of eggs. Life cycle and description Oak leaftier moths lay their eggs in June each year, typically as single eggs on rough-bark twigs, typica ...

Lymantria Dispar
''Lymantria dispar'', also known as the gypsy moth or the spongy moth, is a species of moth in the family Erebidae. ''Lymantria dispar'' is subdivided into several subspecies, with subspecies such as ''L. d. dispar'' and ''L. d. japonica'' being clearly identifiable without ambiguity. ''Lymantria dispar'' has been introduced to several continents and is now found in Europe, Africa, Asia, North America and South America. The polyphagous larvae live on a variety of deciduous and coniferous trees and can cause severe damage in years of mass reproduction. Due to these features, ''Lymantria dispar'' is listed among the world's 100 worst invasive alien species. Etymology The name “gypsy moth” does not have conclusive origins, however it has been in use since 1908. Moths of the subfamily Lymantriinae are commonly called tussock moths due to the tussock-like tufts of hair on the caterpillars.The Gypsy Moth: Research Toward Integrated Pest Management, United States Depar ...

Chestnut Blight
The pathogenic fungus ''Cryphonectria parasitica'' (formerly ''Endothia parasitica'') is a member of the Ascomycota (sac fungi). This necrotrophic fungus is native to East Asia and South East Asia and was introduced into Europe and North America in the early 1900s. The fungus spread rapidly and caused significant tree loss in both regions. Overview ''Cryphonectria parasitica'' is a parasitic fungus of chestnut trees. This disease came to be known as chestnut blight. Naturally found in South East Asia, accidental introductions led to invasive populations of ''C. parasitica'' in North America and Europe. The fungal disease has had a devastating economic and social impact on communities in the eastern United States. In the first half of the 20th century it killed an estimated four billion trees; or, by another count, 3.5 billion trees through 2013. Less severe impacts have occurred in Europe due to widespread CHV1-induced ''hypovirulence''. CHV1 is one of at least two viral pathog ...

Mast (botany)
Mast is the fruit of forest trees and shrubs, such as acorns and other nuts. The term derives from the Old English ''mæst'', meaning the nuts of forest trees that have accumulated on the ground, especially those used historically for fattening domestic pigs, and as food resources for wildlife. In the aseasonal tropics of Southeast Asia, entire forests, including hundreds of species of trees and shrubs, are known to mast at irregular periods of 2–12 years. More generally, mast is considered the edible vegetative or reproductive parts produced by woody species of plants, i.e. trees and shrubs, that wildlife and some domestic animals consume as a food source. Mast is generated in large quantities during long-interval but regularly recurring phenological events known as mast seeding or masting. Such events are population-level phenomena hypothesized to be driven by a wide variety of factors, depending on the plant species involved, including availability of nutrients, economies of ...

Understory

English serves as the medium of inter-Commonwealth relations. Many ...), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In Temperate broadleaf and mixed forest, temperate deciduous forests, many understory plants start into growth earlier in the year ...

Overstory
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs s ...
