Doumergue's Fringe-fingered Lizard
Doumergue's fringe-fingered lizard (''Acanthodactylus spinicauda''), also known commonly as Doumergue's fringe-toed lizard, is a species of lizard in the family Lacertidae. Geographic range ''A. spinicauda'' is found in Algeria. Habitat The natural habitats of ''A. spinicauda'' are open stony and flat sandy places. Reproduction ''A. spinicauda'' is oviparous, and the average clutch A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). ... size is 8 eggs. Conservation status The species ''A. spinicauda'' is considered " Critically Endangered" because of small geographic range, fragmented distribution within that range, and habitat loss. The species was collected for the first time in 1901. After more than a century no individuals were ever discovered again until recently in 2015, a di ...

François Doumergue
François Doumergue (11 May 1858, Carcassonne – 24 December 1938, Oran, Algeria) was a French naturalist remembered for his scientific investigations within the department of Oran. From September 1886 onward, he taught classes at the ''Lycée d'Oran''. As a naturalist, he made contributions in the fields of paleontology, geology, botany and zoology. He was a member of the ''Société de géographie et d'archéologie d'Oran'', serving as its president from 1912 to 1920, and then again from 1924 to 1928. Beginning in 1886, with zoologist Paul Maurice Pallary, he conducted paleontological explorations of several cave sites in the vicinity of Oran. In 1892 at the so-called "Abri Alain" (Kouchet El-Djir), the two men uncovered evidence of prehistoric human activity dating back many centuries. Some of the archaeological pieces that were excavated later became part of the Ahmed Zabana National Museum in Oran. A herpetological Herpetology (from Greek ἑρπετόν ''herpetó ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Described In 1901
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians ( tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...

Endemic Fauna Of Algeria
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] |
Acanthodactylus
''Acanthodactylus'' is a genus of lacertid lizards, commonly referred to as fringe-fingered lizards, fringe-toed lizards (though the latter common name is also used for the New World lizard genus ''Uma''), and spiny-toed lizards. Geographic range The approximately 40 species in the genus ''Acanthodactylus'' are native to a wide area in North Africa, southern Europe and Western Asia; across the Sahara Desert, to the Iberian Peninsula, and east through the Arabian Peninsula, to Afghanistan and western India. Salvador A (1982)"A revision of the lizards of the genus ''Acanthodactylus'' (Sauria: Lacertidae)".''Bonn. Zool. Monogr.'' (16): 1–167. Habitat Though lizards of the genus ''Acanthodactylus'' prefer dry and sparsely vegetated regions, they are not strictly tied to an arid terrain; so it is not uncommon to come across them in various environments. Description Members of the genus ''Acanthodactylus'' possess the following combination of traits: *Lacking occipital scales, *Fl ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , ...

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, an ...

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] |

Lacertidae
The Lacertidae are the family of the wall lizards, true lizards, or sometimes simply lacertas, which are native to Afro-Eurasia. It is a diverse family with at least 300 species in 39 genera. They represent the dominant group of reptiles found in Europe. The group includes the genus ''Lacerta'', which contains some of the most commonly seen lizard (thus "true" lizard) species in Europe. Habitat The European and Mediterranean species of lacertids live mainly in forest and scrub habitats. ''Eremias'' and ''Ophisops'' species replace these in the grassland and desert habitats of Asia. African species usually live in rocky, arid areas. ''Holaspis'' species are among the few arboreal lacertids, and its two species, ''Holaspis guentheri'' and ''Holaspis laevis'', are gliders (although apparently poor ones), using their broad tail and flattened body as an aerofoil. Description Lacertids are small or medium-sized lizards. Most species are less than 9 cm long, excluding the tail, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
