Pelophylax Lessonae
The pool frog (''Pelophylax lessonae'') is a European frog in the family Ranidae. Its specific name was chosen by the Italian herpetologist Lorenzo Camerano in 1882, in order to honour his master Michele Lessona. Description The pool frog is a small frog which rarely grows to more than 8 cm long, although females can grow up to 9 cm. Males are typically around 5 cm long, while females are around 6–6.5 cm long. These frogs are brown or green, with dark blotches along their backs, a pair of ridges running from each eye and a cream or yellow stripe down the middle of the frog's back. The vocal sacs on the male are cream or even white. Distribution The pool frog is found across most of central Europe from the west coast of northern France to the Western part of Russia. There are also small populations of pool frogs in the United Kingdom, Spain, Sweden and Norway. Pool frogs were previously thought to be a non-native species in the UK, but studies have shown that English pool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorenzo Camerano
Lorenzo Camerano (9 April 1856 Biella – 22 November 1917 Turin) was an Italian herpetologist and entomologist. Born in Biella in 1856 he studied in Bologna and Torino, where he settled in order to take, between 1871 and 1873, a painting course held by Fontanesi at the local Art Academy. Camerano worked as a painter for the Turin Zoology Museum, then directed by the great zoologist Michele Lessona. Fascinated by the strong personality of Lessona, he started a natural sciences course at the local university and graduated in 1878. After having held several positions as assistant he became professor in 1880 and attained a permanent tenure in Cagliari University. A little later he went back to Turin where he was assigned the chair of comparative anatomy, that he held till 1915. Camerano also was chancellor of the University of Turin between 1907 and 1910, and was elected an Italian senator in 1909. Besides his large scientific production (more than 300 titles), which included d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herpetological Conservation Trust
The Herpetological Conservation Trust (HCT) was a British wildlife charity for the conservation of herpetofauna: amphibians and reptiles. It was founded in 1989 by Vincent Weir and Ian Swingland of DICE and launched at the First World Congress of Herpetology in Canterbury that year. In July 2009, HCT evolved into Amphibian and Reptile Conservation Amphibian and Reptile Conservation (ARC) is a British wildlife charity formed in July 2009 by the Herpetological Conservation Trust The Herpetological Conservation Trust (HCT) was a British wildlife charity for the conservation of herpetofauna ..., a new voice for conserving frogs, toads, newts, snakes and lizards.

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 ...

Pelophylax
''Pelophylax'' is a genus of true frogs widespread in Eurasia, with a few species ranging into northern Africa. This genus was erected by Leopold Fitzinger in 1843 to accommodate the green frogs of the Old World, which he considered distinct from the brown pond frogs of Carl Linnaeus' genus ''Rana''. They are also known as water frogs, as they spend much of the summer living in aquatic habitat; the pond frogs can be found more often, by comparison, on dry land, as long as there is sufficient humidity. Yet there are species of Eurasian green frogs – the Central Asian '' P. terentievi'', or the Sahara frog (''P. saharicus'') – which inhabit waterholes in the desert. Systematics and taxonomy Most authors throughout the 19th and 20th century disagreed with Fitzinger's assessment. The green frogs were included again with the brown frogs, in line with the tendency to place any frog similar in habitus to the common frog (''R. temporaria'') in ''Rana''. That genus, ...

Edible Frog
The edible frog (''Pelophylax'' kl. ''esculentus'') is a species of common European frog, also known as the common water frog or green frog (however, this latter term is also used for the North American species ''Rana clamitans''). It is used for food, particularly in France for the delicacy frog legs. Females are between 5 and 9 cm long, males between 6 and 11 cm. This widespread and common frog has many common names, including European dark-spotted frog, European black-spotted pond frog, and European black-spotted frog. Distribution ''Pelophylax esculentus'' is endemic to Europe. It naturally occurs from the northern half of France to western Russia, and from Estonia and Denmark to Bulgaria and northern Italy. The edible frog is introduced in Spain, Norway and the United Kingdom. The natural range is nearly identical to that of '' P. lessonae''. Hybridogenesis ''Pelophylax'' kl.

Marsh Frog
The marsh frog (''Pelophylax ridibundus'') is a species of water frog native to Europe and parts of western Asia. Description The marsh frog is the largest type of frog in most of its range, with males growing to a size around 100 mm (3.9 in) SVL and females slightly larger (4 in) SVL. There is a large variation in colour and pattern, ranging from dark green to brown or grey, sometimes with some lighter green lines; a lighter line on the back is generally present. The frog will usually be darker coloured in early spring to absorb heat more efficiently. Tadpoles can reach up to 190 mm (7.3 in) in length, but this usually occurs in places with long winters where the tadpole has time to grow. Distribution and habitat They occur in a large part of Europe starting from western France and spreading out into the Middle East and about a quarter into Russia. There are also isolated populations in Saudi Arabia and the Russian Far East, along with some introduced populations in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breckland
Breckland in Norfolk and Suffolk is a 39,433 hectare Special Protection Area (SPA) under the European Union Directive on the Conservation of Wild Birds. The SPA partly overlaps the 7,544 hectare Breckland Special Area of Conservation. As a landscape region it is an unusual natural habitat of England. It comprises the gorse-covered sandy heath that lies mostly in the south of the county of Norfolk but also in the north of Suffolk. An area of considerable interest for its unusual flora and fauna, it lies to the east of another unusual habitat, the Fens, and to the south west of the Broads. The typical tree of this area is the Scots pine. Breckland is one of the driest areas in England. The area of Breckland has been substantially reduced in the twentieth century by the impact of modern farming and the creation in 1914 of Thetford Forest. However substantial areas have been preserved, not least by the presence of the British Army on the Stanford Battle Area. During the Prehisto ...

English Nature
English Nature was the United Kingdom government agency that promoted the conservation of wildlife, geology and wild places throughout England between 1990 and 2006. It was a non-departmental public body funded by the Department for Environment, Food and Rural Affairs (DEFRA) and gave statutory advice, grants and issued licences. The Nature Conservancy Council (NCC) (formerly the Nature Conservancy) was established by the National Parks and Access to the Countryside Act 1949 to cover nature conservation issues across the whole of Great Britain. The NCC was split into four by the Environmental Protection Act 1990—its English duties being given to English Nature. In Scotland, its functions were merged with those of the Countryside Commission for Scotland to form Scottish Natural Heritage, and similarly in Wales there was a merger to form the Countryside Council for Wales. A much smaller body, the Joint Nature Conservation Committee (JNCC), supported all three agencies. The Engl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
