Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as ''Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and collards), ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Ailanthus Altissima
''Ailanthus altissima'' , commonly known as tree of heaven, ailanthus, varnish tree, or in Chinese as ''chouchun'' (), is a deciduous tree in the family Simaroubaceae. It is native to northeast and central China, and Taiwan. Unlike other members of the genus ''Ailanthus'', it is found in temperate climates rather than the tropics. The tree grows rapidly, and is capable of reaching heights of in 25 years. While the species rarely lives more than 50 years, some specimens exceed 100 years of age. Its suckering ability allows this tree to clone itself indefinitely. It is considered a noxious weed and vigorous invasive species, and one of the worst invasive plant species in Europe and North America. In 21st-century North America, the invasiveness of the species has been compounded by its harboring of the also destructive and invasive spotted lanternfly. Description ''A. altissima'' is a medium-sized tree that reaches heights between with a diameter at breast height of ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ...

Deer
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as ...

Hiking
Hiking is a long, vigorous walk, usually on trails or footpaths in the countryside. Walking for pleasure developed in Europe during the eighteenth century.AMATO, JOSEPH A. "Mind over Foot: Romantic Walking and Rambling." In ''On Foot: A History of Walking'', 101-24. NYU Press, 2004. Accessed March 1, 2021. http://www.jstor.org/stable/j.ctt9qg056.7. Religious pilgrimages have existed much longer but they involve walking long distances for a spiritual purpose associated with specific religions. "Hiking" is the preferred term in Canada and the United States; the term "walking" is used in these regions for shorter, particularly urban walks. In the United Kingdom and the Republic of Ireland, the word "walking" describes all forms of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling , hillwalking, and fell walking (a term mostly used for hillwalking in northern England). The term bushwalking is end ...

Railroad
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ...

Gypsy Moth
''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 Department o ...

Dimilin
Diflubenzuron is an insecticide of the benzoylurea class. It is used in forest management and on field crops to selectively control insect pests, particularly forest tent caterpillar moths, boll weevils, gypsy moths, and other types of moths. It is a widely used larvicide in India for control of mosquito larvae by public health authorities. Diflubenzuron is approved by the WHO Pesticide Evaluation Scheme. Mechanism of action The mechanism of action of diflubenzuron involves inhibiting the production of chitin which is used by an insect to build its exoskeleton. It triggers insect larvae to molt early without a properly formed exoskeleton, resulting in the death of the larvae. Environmental toxicity Diflubenzuron has been evaluated by the United States Environmental Protection Agency (EPA), and it is classified as non-carcinogenic. 4-Chloroaniline, a metabolite of diflubenzuron which has been classified as a carcinogen, is produced after diflubenzuron has been ingeste ...

Pesticide
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus ''Alternaria solani'' is used to combat the aquatic weed ''Salvinia''. In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or a ...

Pyrgus Wyandot
''Pyrgus centaureae wyandot'', the Appalachian grizzled skipper, is a small, brown, gray and white butterfly known to inhabit parts of the Appalachian highlands and Northern Michigan. It can be identified by its characteristic checkered wing pattern formed by the scales on the fore- and hindwings. The butterflies are known to prefer sites with minimal vegetation, such as open areas in hardwood forests, as well as sites of recent disturbance. The skipper's main larval food plants include Canada cinquefoil (''Potentilla canadensis'') and wild strawberry ('' Fragaria virginiana'') depending on the specific population's range. The butterfly is listed as a federal species of concern and holds a stated-endangered title in Ohio and New Jersey. Description The Appalachian grizzled skipper butterfly is a subspecies of the butterfly ''Pyrgus centaureae The northern grizzled skipper (''Pyrgus centaureae'') is a species of skipper butterfly (family Hesperiidae) with a range in N ...
