Iberian Emerald Lizard
The Iberian emerald lizard (''Lacerta schreiberi''), also known commonly as Schreiber's green lizard, is a species of lizard in the family Lacertidae. The species is endemic to the Iberian Peninsula. Etymology The specific name, ''schreiberi'', is in honor of Austrian zoologist Egid Schreiber (1836–1913), author of ''Herpetologia Europaea'' (1875). It is known as ''Lagarto-de-água'' (water lizard) in Portuguese and ''lagarto verdinegro'' (green and black lizard) in Spanish. Geographic range ''Lacerta schreiberi'' is found in Portugal and Spain. Habitat The natural habitats of ''L. schreiberi'' are temperate forests and shrublands, Mediterranean-type shrubby vegetation, rivers, and pastureland. Conservation status ''Lacerta schreiberi'' is threatened by habitat loss. Description A large species, ''L. schreiberi'' measures about snout-to-vent (SVL); including the tail, it measures about . Diet ''Lacerta schreiberi'' is mainly insectivorous, though it also preys on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Von Bedriaga
Jacques Vladimir von Bedriaga (last name sometimes spelled Bedryagha) (1854 - 1906) was a Russian herpetologist who was a native of Kriniz, a village near Voronezh. In scientific papers Bedriaga would sometimes alter his name to agree with the language of the country in which he was publishing. As a result, the following variations are encountered: Jacob Vladimirovich Bedriaga, Johann von Bedriaga, and Jean de Bedriaga. Biography He studied sciences at Moscow University under the direction of Anatoli Bogdanov (1834-1896), and afterwards moved to Germany, where he studied at the University of Jena with Ernst Haeckel (1834-1919) and Carl Gegenbaur (1826-1903). In 1875, he obtained his doctorate with a thesis on the urogenital organs of reptiles. After graduation, Bedriaga continued his research on reptiles with Gegenbaur, and made frequent scientific trips to regions around the Mediterranean. In 1880 he published an important work on Greek herpetology called ''Die Amphibien und R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Reptiles Of The Iberian Peninsula
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] |
Lacerta (genus)
''Lacerta'' is a genus of lizards of the family Lacertidae. Taxonomy ''Lacerta'' was a fairly diverse genus containing around 40 species, until it was "split" into nine genera in 2007 by Arnold, Arribas & Carranza. Fossil record The earliest known members of the genus ''Lacerta'' are known from early Miocene epoch fossils indistinguishable in anatomy from the modern green lizards such as ''Lacerta viridis''. Species The genus ''Lacerta'' contains the following species. *''Lacerta agilis'' – sand lizard *''Lacerta bilineata'' – western green lizard *'' Lacerta citrovittata'' – Tinos green lizard *'' Lacerta diplochondrodes'' – Rhodos green lizard *'' Lacerta media'' *'' Lacerta pamphylica'' *''Lacerta schreiberi'' – Iberian emerald lizard *'' Lacerta strigata'' – Caucasus emerald lizard *'' Lacerta trilineata'' - Balkan green lizard, Balkan emerald lizard *''Lacerta viridis'' – European green lizard Some species formerly in ''Lacerta'' Arranged alpha ...

Clutch (eggs)
__NOTOC__ A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in ''double-clutching''. The technique is used to double the production of a species' eggs, in the California condor case, specifically to increase population size. The act of putting one's hand in a nest to remove eggs is known as "dipping the clutch". Size Clutch size differs greatly between species, sometimes even within the same genus. It may also differ within the same species due to many factors including habitat, health, nutrition, predation pressures, and time of year. Clutch size variation can also reflect variation in optimal reproduction effort. In birds, clutch size can vary within a species due to various features (age and health of laying female, ability of male to supply food, and abundan ...

Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iberian Wall Lizard
''Podarcis hispanicus,'' also known as Iberian wall lizard, is a small wall lizard species of the genus ''Podarcis''. It is found in the Iberian peninsula, in northwestern Africa and in coastal districts in Languedoc-Roussillon in France. In Spanish, this lizard is commonly called ''lagartija Ibérica''. The Iberian wall lizard is very agile and can move rapidly across a rock face. Males are somewhat territorial. Females lay clutches of one to five oval eggs which hatch in about eight weeks. At birth, the juveniles have a snout-to-vent length of . The lifespan of this lizard is about four years. History and taxonomy ''Podarcis hispaniscus'' was first described in Steindachner’s works in 1870 and are composed of multiple distinct lineages. Most research has been done on the Spanish Levant form of ''Podarcis hispanicus''. They are commonly found in the Baetic mountains and south of Rio Guadalquivir. The North African Podarcis hispaniscus are now ranked as ''Padarcis vaucheri'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insectivorous
A robber fly eating a hoverfly An insectivore is a carnivorous animal or plant that eats insects. An alternative term is entomophage, which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each other remain in the order Eulipotyphla. Although individually small, insects exist in enormous numbers. Insects make up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tail
The tail is the section at the rear end of certain kinds of animals’ bodies; in general, the term refers to a distinct, flexible appendage to the torso. It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds. While tails are primarily a feature of vertebrates, some invertebrates including scorpions and springtails, as well as snails and slugs, have tail-like appendages that are sometimes referred to as tails. Tailed objects are sometimes referred to as "caudate" and the part of the body associated with or proximal to the tail are given the adjective "caudal". Function Animal tails are used in a variety of ways. They provide a source of locomotion for fish and some other forms of marine life. Many land animals use their tails to brush away flies and other biting insects. Most canines use their tails to comunicate mood and intention . Some species, including cats and kangaroos, use their tails for balance; and some, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...
