In creating models with PFTs, areas as small as 1 km 2 are modeled by defining the predominant plant type for that area, interpreted from satellite data [1] or other means. For each plant functional type, a number of key parameters are defined, such as fecundity , competitiveness , resorption (rate at which plant decays and returns nutrients to ...
Polyculture is the growing of multiple crops together in the same place at the same time. It has traditionally been the most prevalent form of agriculture. [1] Regions where polycultures form a substantial part of agriculture include the Himalayas, Eastern Asia, South America, and Africa. [2]
The deserts in California receive between 2 and 10 inches (51 and 254 mm) of rain per year. [6] Plants in these deserts are brush and scrub, adapted to the low rainfall. Common plant species include creosote bush, blackbrush, greasewood, saltbush, big sagebrush, low sagebrush, and shadscale. [6]
Examples of patterned vegetation include fir waves, tiger bush, and string bog. The patterns typically arise from an interplay of phenomena that differentially encourage plant growth or mortality. A coherent pattern arises because there is a strong directional component to these phenomena, such as wind in the case of fir waves, or surface ...
Extent of temperate broadleaf and mixed forests An example of temperate broadleaf and mixed forest in La Mauricie National Park, Quebec.. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.
Phytosociology, also known as phytocoenology or simply plant sociology, is the study of groups of species of plant that are usually found together.Phytosociology aims to empirically describe the vegetative environment of a given territory.
Climax vegetation vulnerable to a catastrophic event such as a wildfire. For example, in California, chaparral vegetation is the final vegetation. The wildfire removes the mature vegetation and decomposers. A rapid development of herbaceous vegetation follows until the shrub dominance is re-established. This is known as catastrophic climax ...
The cyclic model of succession was proposed in 1947 by British ecologist Alexander Watt.In a seminal paper on vegetation patterns in grass, heath, and bog communities, [4] Watt describes the plant community is a regenerating entity consisting of a "space-time mosaic" of species, whose cyclic behavior can be characterized by patch dynamics.
