Arthur Tansley (was an English botanist and a pioneer in the science of ecology. Educated at Highgate School, University College London and Trinity College, Cambridge, Tansley taught at these universities and at Oxford, where he served as Sherardian Professor of Botany until his retirement in 1937. Tansley founded the New Phytologist in 1902 and served as its editor until 1931. He was a pioneer of the science of ecology in Britain, being heavily influenced by the work of Danish botanist Eugenius Warming, and introduced the concept of the ecosystem into biology. Tansley was a founding member of the first professional society of ecologists, the Central Committee for the Survey and Study of British Vegetation, which later organised the British Ecological Society, and served as its first president and founding editor of the Journal of Ecology. Tansley also served as the first chairman of the British Nature Conservancy)

U-shaped valleys, trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. They have a characteristic U shape in cross-section, with steep, straight sides and a flat or rounded bottom.

Vicia Americana (It is a common understory plant in many types of forest and other habitats such as chaparral and it provides forage for wild and domesticated animals. This vetch is used to reclaim burned or disturbed land, such as that which has been cleared by wildfire or altered by human activities such as mining or construction. It is drought-tolerant and thrives in both dry and moist, and sandy or coarse loamy soil habitats)

Wasteland or waste land may refer to: Desert or barren, area; an uncultivated area of land, whether wooded or not, whether common land or not.

Xerocole (is a general term referring to any animal that is adapted to live in a desert. The main challenges xerocoles must overcome are lack of water and excessive heat. To conserve water they avoid evaporation and concentrate excretions. Some are so adept at conserving water or obtaining it from food that they do not need to drink at all. To escape the desert heat, xerocoles tend to be either nocturnal or crepuscular)

Yarrow is cultivated as an ornamental plant by many plant nurseries, but it is so much more than just a pretty face! It is extremely versatile, able to grow in a variety of soils and conditions. It is an excellent contender for the wildlife garden as its flowers are a hub of activity in the summer.  A good bee plant, it is an important nectar source for many insects.  Yarrow has an excellent reputation and is widely employed in herbal medicine, administered both internally and externally for a wide range of ailments

Zooplankton (are organisms drifting in oceans, seas, and bodies of fresh water. The word zooplankton is derived from the Greek zoon (ζ?ον), meaning "animal", and planktos (πλαγκτ?ς), meaning "wanderer" or "drifter". Individual zooplankton are usually microscopic, but some (such as jellyfish) are larger and visible to the naked eye)
