Ivy-leaved Toadflax
''Cymbalaria muralis'', commonly called ivy-leaved toadflax or Kenilworth ivy, is a low, spreading, viney plant with small purple flowers, native to southern Europe. It belongs to the plantain family ( Plantaginaceae), and is introduced in North America, Australia, and elsewhere. The flower stalk is unusual for seeking light until it is fertilized, after which it grows away from the light. Other names include coliseum ivy, Oxford ivy, mother of thousands, pennywort, and wandering sailor. Description and habitat It spreads quickly, growing up to tall – it commonly grows in rock and wall crevices, and along footpaths. The leaves are evergreen, rounded to heart-shaped, long and wide, 3–7-lobed, alternating on thin stems. The flowers are very small but distinctly spurred, similar in shape to snapdragon flowers. Flowers from May to September. File:(MHNT) Cymbalaria muralis.jpg, Plant habit File:(MHNT) Cymbalaria muralis - Leaf.jpg, Leaf File:(MHNT) Cymbalaria muralis - flower.jp ...

Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Phototropic
Phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Negative phototropism is not to be confused with skototropism which is defined as the growth towards darkness, whereas negative phototropism can refer to either the growth away from a light source or towards the darkness. Most plant shoots exhibit positive phototropism, and rearrange their chloroplasts in the leaves to maximize photosynthetic energy and promote growth.Goyal, A., Szarzyns ...

Biodiversity Research And Conservation
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic ('' genetic variability''), species ('' species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Alps (Europe)
The Southern Alps are a geological subdivision of Alps that are found south of the Periadriatic Seam, a major geological faultzone across the Alps. The southern Alps contain almost the same area as the Southern Limestone Alps. The rocks of the southern Alps gradually go over in the ''Dinarides'' or Dinaric Alps to the south-east. In the south-west they disappear below recent sediments of the Po basin that are lying discordant on top of them. Lithology The Southern Alps are composed of material from the Adriatic or Apulian tectonic plate, the area is a part of this plate. These are mainly Mesozoic sedimentary rocks, most of them limestones. Tectonics In contrast to the Central Eastern Alps north of the Periadriatic Seam, the geology of the Southern Alps is not characterized by nappes. Neither are high grade metamorphic rocks common in the region. The Southern Alps are tectonically characterized by large scale thrusting and folding to the south, the dominant ''vergence'' (directi ...

Cymbalaria Muralis G
''Cymbalaria'' is a genus of about 10 species of herbaceous perennial plants previously placed in the family Scrophulariaceae, but recently shown by genetic research to be in the much enlarged family Plantaginaceae. The genus is native to southern Europe. It is closely related to the genera ''Linaria'' and '' Antirrhinum'', differing in having creeping growth and flowers borne singly rather than in dense erect spikes. The common name toadflax is shared with ''Linaria'' and other related genera. The scientific name means "resembling a cymbal" for the somewhat rounded leaves. By far the best known species is ''Cymbalaria muralis'' (also called ivy-leaved toadflax, and Kenilworth ivy), native to southwest Europe. It has widely naturalised elsewhere and is commonly sold as a garden plant. ''C. muralis'' characteristically grows in sheltered crevices in walls and pathways, or in rocks and scree, making a trailing or scrambling plant up to 1 m long. Species list Accepted species are ...
