Salamandra Lanzai
Lanza's alpine salamander or the large alpine salamander (''Salamandra lanzai'') is a species of salamander in the family Salamandridae, found in France and Italy. Its natural habitats are forests, grasslands, and pasturelands, all of which are temperate. It is threatened by habitat loss and potentially in the future by the fungal disease ''Batrachochytrium salamandrivorans''. History It was described by Nascetti, Andreone, Capula and Bullini in 1988. The generic name is from Greek which translates as "salamander", and the specific name is for Benedetto Lanza, an Italian herpetologist. Description The species has a flat head and measures between in length. Its tail's tip is either rounded or pointed, with or without paravertebral glands. Due to its black colour, it is similar to the other alpine salamander (''Salamandra atra''). Distribution The species can be found in the Cottian Alps near Monviso, and in Guil Valley of southeastern France. It can also be found in north ...

Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germanasca
The Germanasca (also in Piedmontese ''Germanasca'') is a Italian torrent, which runs through the Metropolitan City of Turin. It is a tributary of the Chisone, into which it flows near Perosa Argentina. The valley formed by the river is known as Val Germanasca. Geography The stream is formed from ''Lago Verde'', a small Alpine lake in the Cottian Alps, and initially runs northwards, before reaching the ''comune'' of Salza di Pinerolo and turning east. It then receives the waters of the ''Germanasca di Salza'' and ''Germanasca di Massello'' increasing a lot its average discharge. After the end of its course through the Germanasca Valley it reaches the Chisone at Perosa Argentina Perosa Argentina (French: Pérouse) is a ''comune'' (municipality) in the Metropolitan City of Turin in the Italian region Piedmont, located about northwest of Turin, in the val Chisone. Perosa Argentina borders the following municipalities: Co .... Notes and references Other projects Rivers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avalanche
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be set off spontaneously, by such factors as increased precipitation or snowpack weakening, or by external means such as humans, animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, mudslides, rock slides, and serac collapses. They are also different from large scale movement ...

Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes th ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

Slug
Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word ''slug'' is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs (this is in contrast to the common name ''snail'', which applies to gastropods that have a coiled shell large enough that they can fully retract their soft parts into it). Various taxonomic families of land slugs form part of several quite different evolutionary lineages, which also include snails. Thus, the various families of slugs are not closely related, despite a superficial similarity in the overall body form. The shell-less condition has arisen many times independently as an example of convergent evolution, and thus the category "slug" is polyphyletic. Taxonomy Of the six orders of Pulmonata, two – the Onchidiacea and Soleolifera – solely comprise slugs. A third family, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime Alps
The Maritime Alps (french: Alpes Maritimes ; it, Alpi Marittime ) are a mountain range in the southwestern part of the Alps. They form the border between the regions of France, French region of Provence-Alpes-Côte d'Azur and the regions of Italy, Italian regions of Piedmont and Liguria. They are the southernmost part of the Alps. Geography Administratively the range is divided between the Provinces of Italy, Italian provinces of Province of Cuneo, Cuneo and Province of Imperia, Imperia (eastern slopes) and the Departments of France, French department of Alpes-Maritimes (western slopes). The Maritime Alps are drained by the rivers Roya (river), Roya, Var River, Var and Verdon River, Verdon and their tributaries on the French side; by the Stura di Demonte and other tributaries of the Tanaro River, Tanaro and Po River, Po on the Italian side. There are many attractive perched villages, such as Belvédère at the entrance to the spectacular Gordolasque valley, some concealing unex ...

Museum La Specola, Florence
The Museum of Zoology and Natural History, best known as La Specola, is an eclectic natural history museum in Florence, central Italy, located next to the Pitti Palace. The name '' Specola'' means observatory, a reference to the astronomical observatory founded there in 1790. It now forms part of the Museo di Storia Naturale di Firenze. This museum is part of what are now six different collections at four different sites for the Museo di Storia Naturale di Firenze. History The museum has deep ties with history; parts of the collection can be traced back to the Medici Family. It is known for its collection of wax anatomical models from the 18th century. It is the oldest scientific Museum of Europe. This museum is located in the former Palazzo Torrigani at Via Romana 17, near the Pitti Palace. The Imperial Regio Museo di Fisica e Storia Naturale (The Imperial-Royal Museum for Physics and Natural History) was founded in 1771 by Grand Duke Peter Leopold to publicly display the large ...
