Ambrosi's Cave Salamander
Ambrosi's cave salamander or the Spezia cave salamander (''Speleomantes ambrosii'') is a species of salamander in the family Plethodontidae. Endemic to northwestern Italy, its natural habitats are temperate forests, rocky areas, caves, and subterranean habitats (other than caves). It is threatened by habitat loss. Description Ambrosi's cave salamander has short, stout limbs, pointed toes and a short tail and grows to around including the tail. There is a ridge known as a canthus between the snout and the eye. The colour is variable, being brown to black with marbling, mottling or streaking in grey, green, yellow, red, pink or brown. Some individuals are a uniform brown or black colour. The underparts are also dark with paler markings. Distribution and habitat Ambrosi's cave salamander is endemic to a small area of northwestern Italy, occurring at scattered locations in La Spezia province. Despite its name, it is not restricted to caves though it retreats under stones, logs and int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Italian Cave Salamander
The Italian cave salamander (''Speleomantes italicus'') is a species of salamander in the family Plethodontidae. Endemic to Italy, its natural habitats are temperate forests, rocky areas, caves, and subterranean habitats (other than caves). It is threatened by habitat loss. Description The Italian cave salamander is a slender species with short limbs and grows to a length of about including a short tail. The head is broad with prominent eyes and there is a distinct groove between the nostrils and the edge of the lips. The feet are partially webbed. It is dark in colour with mottled reddish or yellowish markings and a dark belly. In the north of its range it is more variable in colour and sometimes hybridises with Ambrosi's cave salamander (''Speleomantes ambrosii''). Distribution and habitat The Italian cave salamander is native to northern Italy where it is found in the northern and central Apennine Mountains. Its range extends from the Province of Lucca and Province of Reggio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Italy
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Europe
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...

Cave Salamanders
A cave salamander is a type of salamander that primarily or exclusively inhabits caves, a group that includes several species. Some of these animals have developed special, even extreme, adaptations to their subterranean environments. Some species have only rudimentary (or even absent) eyes (''blind salamanders''). Others lack pigmentation, rendering them a pale yellowish or pinkish color (e.g., ''Eurycea rathbuni''). With the notable exception of ''Proteus anguinus'', all "cave salamanders" are members of the family Plethodontidae ("lungless salamanders"). History The first dedicated scientific study of a cave animal was focused upon a cave salamander, ''Proteus anguinus''. It was originally identified as a "dragon's larva" by Johann Weikhard von Valvasor in 1689. Later, the Austrian naturalist Joseph Nicolaus Lorenz described it scientifically in 1768. Another early scientific description of a cave salamander was undertaken by Constantine Samuel Rafinesque in 1822 while he w ...

Speleomantes
''Speleomantes'', or European cave salamanders, are a genus of salamander in the family Plethodontidae, or lungless salamanders. It is one of two genera in the family to inhabit the Old World (the other being '' Karsenia''), with the remaining 250 or so species being found in North, Central and South America. The genus is endemic to Italy and a few nearby areas (San Marino, Monaco, and eastern Provence). Characteristics Until recently, ''Speleomantes'' was combined with the web-toed salamander genus ''Hydromantes'' from the Sierra Nevada range of California, which are their closest relatives, and are still combined by some herpetologists. They lack lungs; respiration takes place through the skin, which must be kept moist, and the lining of the mouth. The head is broad and distinct with prominent eyes. There are characteristic deep nasolabial grooves between the nostrils and the edge of the lips. The tongue has a broad tip and is extensible, being shot forward to catch prey. The ...

Parco Nazionale Delle Cinque Terre
Cinque Terre National Park (Italian: ''Parco Nazionale delle Cinque Terre'') is a protected area inducted as an Italian national park in 1999. Located in the province of La Spezia, Liguria, northern Italy, it is the smallest national park in Italy at 4,300 acres, but also the densest with 5,000 permanent inhabitants among the five towns. In addition to the territory of the towns of Cinque Terre (Riomaggiore, Manarola, Corniglia, Vernazza and Monterosso al Mare), the Cinque Terre National Park encompasses parts of the communes of Levanto (Punta Mesco) and La Spezia (Campiglia Sunsets). Cinque Terre was included as a UNESCO World Heritage Site in 1999. The collection of five cliff-side towns on the Ligurian Coast linked by a series of trails highlights a delicate relationship between man and the environment. As modification of the landscape has been so vital for the area's development and tourist industry, the National Park is an essential tool in preserving and maintaining the natur ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is ...

Plethodontidae
Plethodontidae, or lungless salamanders, are a family of salamanders. Most species are native to the Western Hemisphere, from British Columbia to Brazil, although a few species are found in Sardinia, Europe south of the Alps, and South Korea. In terms of number of species, they are by far the largest group of salamanders. Biology Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature adults. Direct development is correlated with changes in the developmental characteristics of plethodontids compared to other families of salamanders including increases in egg size and duration of embryonic development. Additionally, the evolutionary loss of the aquatic larval stage is related to a diminishing dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Province Of La Spezia
A province is almost always an administrative division within a country or state. The term derives from the ancient Roman ''provincia'', which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy. The term ''province'' has since been adopted by many countries. In some countries with no actual provinces, "the provinces" is a metaphorical term meaning "outside the capital city". While some provinces were produced artificially by colonial powers, others were formed around local groups with their own ethnic identities. Many have their own powers independent of central or federal authority, especially in Canada and Pakistan. In other countries, like China or France, provinces are the creation of central government, with very little autonomy. Etymology The English word ''province'' is attested since about 1330 and derives from the 13th-century Old French , which itself comes from the Latin word , which referred to the sphere o ...
