Salamandra Caucasica
The Caucasian salamander (''Mertensiella caucasica'') is a species of stream-dwelling salamander in the family Salamandridae. This is a salamander of medium size, with a thin, elongated body. It is a relict species, endemic to the south-western Caucasus, in Georgia and Turkey. The subspecies ''M. c. janashvilii'' is found at Mt. Mtirala near Batumi and probably along the Black Sea coast. Habitat, behavior and diet The Caucasian salamander lives along the banks of mountain brooks and small rivers with fast currents, both in the forest belt and above timberline, up to about 2400 m above sea level. The species is secretive and strictly nocturnal, and mates on land. The male uses the protuberance on the upper side of the tail for opening the female's cloaca and passes the spermatophore directly to the female. Their diets consist of invertebrates living in soil or shallow water; an important part of the diet is amphipods. Reproduction Sexual dimorphism is expressed by presence of a h ...

Willy Wolterstorff
Willy Georg Wolterstorff (16 June 1864 in Calbe – 21 January 1943 in Magdeburg) was a German paleontologist and herpetologist. As a child he lost his hearing due to disease, thus finding it necessary to lip-reading, lip-read from an early age. He learned natural sciences through private lessons. After receiving vocational training as a bookbinder, he studied geology from 1884 under Karl von Fritsch (1838-1906) at the University of Halle. At Halle he also received training as a curator. In 1889 he became an assistant to Konrad Oebbeke (1853-1932) at the mineralogical-geological institute at Erlangen, and two years later was appointed curator at the ''Museum für Naturkunde und Vorgeschichte'' (museum of natural history and prehistory) in Magdeburg. After his retirement in 1929, he remained at the Magdeburg museum, performing important functions as a volunteer. Wolterstorff is known for scientific research of "lower vertebrates", in particular investigations involving the syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid collection of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three- state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Areas
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; t ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borjomi
Borjomi ( ka, ბორჯომი ) is a resort town in south-central Georgia with a population of 11,173 (as of 2024). Located 165 km from Tbilisi, it is one of the six municipalities of the Samtskhe–Javakheti region and is situated in the northwestern part of the region in the picturesque Borjomi Gorge on the eastern edge of Borjomi-Kharagauli National Park. The town is noted for its mineral water industry, the Romanov summer palace in Likani and the Borjomi-Kharagauli National Park. Borjomi mineral water is particularly well-known in Georgia as well as other countries that were part of the former Soviet Union; the bottling of mineral water is a major source of income for the area. Because of the supposed curative powers of the area's mineral springs, it is a frequent destination for people with health problems. Borjomi is also home to the most extensive ecologically-themed amusement park in the Caucasus. History In the Middle Ages, the area of what is now Borjom ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Iberian Peninsula
The Iberian Peninsula ( ), also known as Iberia, is a peninsula in south-western Europe. Mostly separated from the rest of the European landmass by the Pyrenees, it includes the territories of peninsular Spain and Continental Portugal, comprising most of the region, as well as the tiny adjuncts of Andorra, Gibraltar, and, pursuant to the traditional definition of the Pyrenees as the peninsula's northeastern boundary, a small part of France. With an area of approximately , and a population of roughly 53 million, it is the second-largest European peninsula by area, after the Scandinavian Peninsula. Etymology The Iberian Peninsula has always been associated with the River Ebro (Ibēros in ancient Greek and Ibērus or Hibērus in Latin). The association was so well known it was hardly necessary to state; for example, Ibēria was the country "this side of the Ibērus" in Strabo. Pliny the Elder, Pliny goes so far as to assert that the Greeks had called "the whole of the peninsula" Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold-striped Salamander
The gold-striped salamander or golden-striped salamander (''Chioglossa lusitanica'') is a species of salamander in the family Salamandridae. It is the only species of the genus ''Chioglossa''. It is found in the north-west of Iberia (in Portugal and Spain) at an altitude of up to 1,300 m. It is threatened by habitat loss. Description The gold-striped salamander is a short-legged salamander with protruding eyes and a tail that makes up 2/3 of its total length. It has a smooth upper side with 10-11 coastal grooves which are dark brown to blackish and usually two parallel golden stripes on the back which can sometimes be broken. It is an agile terrestrial amphibian, and is nocturnal. It may shed its tail like a lizard if it feels threatened, and lives for about eight to 10 years. It feeds primarily on invertebrates, using its sticky tongue to catch them. They mate on land with clutches of 12-20 eggs laid between stones in running water or on the walls of caves. The larvae develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, jellyfish, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis (" hemimetaboly"), or no metamorphosis (" ametaboly"). Generally organisms with a larval stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. Etymology The word ''metamorphosis'' derives from Ancient Greek , "transformation, transforming", from ('), "after" and ('), "form". Hormonal control In insects, growth and metamorphosis are controlled by hormones synthesized by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larvae
A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect developmental biology, development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their Biological life cycle, life cycle. A larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterfly, butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. In the case of smaller primitive arachnids, the larval stage differs by having three instead of four pairs of legs. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
