Royal forestA royal forest, occasionally known as a kingswood (silva regis), is an area of land with different definitions in England, Wales, Scotland and Ireland. The term forest in the ordinary modern understanding refers to an area of wooded land; however, the original medieval sense was closer to the modern idea of a "preserve" – i.e. land legally set aside for specific purposes such as royal hunting – with less emphasis on its composition. There are also differing and contextual interpretations in Continental Europe derived from the Carolingian and Merovingian legal systems.
Northern ItalyNorthern Italy (Italia settentrionale, Nord Italia, Alta Italia or just Nord) is a geographical and cultural region in the northern part of Italy. It consists of eight administrative regions: Aosta Valley, Emilia-Romagna, Friuli-Venezia Giulia, Piedmont, Liguria, Lombardy, Veneto and Trentino-Alto Adige. As of 2014, its population was 27,801,460. Rhaeto-Romance and Gallo-Italic languages are spoken in the region, as opposed to the Italo-Dalmatian languages spoken in the rest of Italy.

Quercus suberQuercus suber, commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus sect. Cerris. It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls. It is native to southwest Europe and northwest Africa. In the Mediterranean basin the tree is an ancient species with fossil remnants dating back to the Tertiary period. It endures drought and makes little demand on the soil quality and is regarded as a defence against desertification.
Deep chlorophyll maximumThe deep chlorophyll maximum (DCM), also called the subsurface chlorophyll maximum, is the region below the surface of water with the maximum concentration of chlorophyll. The DCM generally exists at the same depth as the nutricline, the region of the ocean where the greatest change in the nutrient concentration occurs with depth. A DCM is not always present - sometimes there is more chlorophyll at the surface than at any greater depth - but it is a common feature of most aquatic ecosystems, especially in regions of strong thermal stratification.
Perennial plantA perennial plant or simply perennial is a plant that lives more than two years. The term (per- + -ennial, "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials.
WoodlandA woodland (ˈwʊdlənd) is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the plurale tantum woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Some savannas may also be woodlands, such as savanna woodland, where trees and shrubs form a light canopy. Woodlands may support an understory of shrubs and herbaceous plants including grasses.
Genetic assimilationGenetic assimilation is a process described by Conrad H. Waddington by which a phenotype originally produced in response to an environmental condition, such as exposure to a teratogen, later becomes genetically encoded via artificial selection or natural selection. Despite superficial appearances, this does not require the (Lamarckian) inheritance of acquired characters, although epigenetic inheritance could potentially influence the result.
JungleA jungle is land covered with dense forest and tangled vegetation, usually in tropical climates. Application of the term has varied greatly during the past recent century. The word jungle originates from the Sanskrit word jaṅgala ( जङ्गल), meaning rough and arid. It came into the English language via Hindi in the 18th century. Jāṅgala has also been variously transcribed in English as jangal, jangla, jungal, and juṅgala.
Altitudinal zonationAltitudinal zonation (or elevational zonation) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions. Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, which consequently support different vegetation and animal species. Altitudinal zonation was first hypothesized by geographer Alexander von Humboldt who noticed that temperature drops with increasing elevation.
