Popina Island
Popina Island is a Romanian island in the northern part of the Razelm Lake (Razim). The island spans 98 hectares and it is a protected Nature reserve, reserve, hosting an important nesting area for shelducks. Razelm Lake is the largest natural lake in Romania, p. 14 and the largest permanent water expanse in the Danube Delta, separated from the Black Sea by two long grinds, and flows into Lake Goloviţa through a channel to the south. Fauna Popina Island constitutes an important resting place for bird migration, migratory birds and the nesting place for shelduck (''Tadorna tadorna''). In spring, one can find here swamp and forest birds like: nightingales (''Luscinia megarhynchos''), calandra larks (''Melanocorypha cal ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Razim
This is a list of characters from Anthony Horowitz's ''Alex Rider'' series. This includes characters from the novels, Stormbreaker (film), the film, the graphic novels, and the short stories. Main antagonists Ash Anthony Sean Howell, more commonly referred to as Ash (his initials), is a major character in ''Snakehead (novel), Snakehead''. Ash was born in England and worked for MI6 with his best friend #John Rider, John Rider. When John went undercover within Scorpia, Ash was assigned to monitor his progress from a distance in case his friend got into difficulty. Ash was chosen to lead the mission to "capture" John, when he and Yassen Gregorovich were sent to kill a target in Malta. However, the mission was a near total disaster; due to confusion with two clocks that were out of sync, John and Yassen's arrival took Ash by surprise. When Yassen shot Ash, his body armour meant that he was back on his feet in seconds, but this prompted Yassen to fatally shoot four other agent ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra ...

Loess
Loess (, ; from german: Löss ) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loess or similar deposits. Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs. Properties Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non-stratified and often calcareous. Loess grains are angular, with little polishing or rounding, and composed of crystals of quartz, feldspar, mica and other minerals. Loess can be described as a rich, dust-like soil. Loess deposits may become very thick, more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outcrop
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triassic
The Triassic ( ) is a geologic period and system (stratigraphy), system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago (Year#Abbreviations yr and ya, Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic, Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Scolopendra Cingulata
''Scolopendra cingulata'', also known as Megarian banded centipede, and the Mediterranean banded centipede, is a species of centipede, and "the most common scolopendromorph species in the Mediterranean area". Description The species has alternating bands of black and yellow-gold. At approximately , ''Scolopendra cingulata'' is one of the smallest species in the family Scolopendridae Scolopendridae (or, in older documents, Scolopendridæ) is a family of large centipedes (class Chilopoda). Nearly all species in this family have four ocelli (simple eyes) on each side of the head and only 21 pairs of legs, but there are exceptio .... Its venom is also not as toxic as that of other scolopendrid centipedes. Distribution Widely distributed, this species can be found throughout southern Europe, including Portugal and around the Mediterranean Sea, in such countries as Spain, France, Italy, Croatia and Greece, as well as parts of North Africa and Eastern Europe, in Albania and Ukraine ...

Myriapod
Myriapods () are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13,000 species, all of them terrestrial. The fossil record of myriapods reaches back into the late Silurian, although molecular evidence suggests a diversification in the Cambrian Period, and Cambrian fossils exist which resemble myriapods. The oldest unequivocal myriapod fossil is of the millipede '' Pneumodesmus newmani'', from the late Silurian (428 million years ago). ''P. newmani'' is also important as the earliest known terrestrial animal. The phylogenetic classification of myriapods is still debated. The scientific study of myriapods is myriapodology, and those who study myriapods are myriapodologists. Anatomy Myriapods have a single pair of antennae and, in most cases, simple eyes. Exceptions are the two classes symphylans and pauropods, and the millipede order Polydesmida and the centipede order Geophilomorpha, which are all ey ...

Latrodectus Tredecimguttatus
''Latrodectus tredecimguttatus'', also known as the Mediterranean black widow, or the European black widow, is a species in the genus ''Latrodectus'' of the widow spiders. It is commonly found throughout the Mediterranean region, ranging from southern Iberia to southwest and central Asia, hence the name. Specimens from central Asia are also known by the binomial name ''Latrodectus lugubris''; that name, however, is now considered improper, though it is still commonly found in the literature. ''Latrodectus tredecimguttatus'' was previously considered a subspecies of ''Latrodectus mactans''. Description ''L. tredecimguttatus'' is black in color, similar to most other widow species, and is identified by the thirteen spots which are found on its dorsal abdomen (the species name is Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as ''Biota (ecology), biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontology, Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna of Madagascar, Fauna'' comes from the name Fauna (deity), Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan (god), Pan, and ''panis'' is the Greek language, Greek equivalent of fauna. ''Fauna'' is also ...

Calandra Lark
The calandra lark (''Melanocorypha calandra'') or European calandra-lark breeds in warm temperate countries around the Mediterranean and eastwards through Turkey into northern Iran and southern Russia. It is replaced further east by its relative, the bimaculated lark. Taxonomy and systematics The calandra lark was originally placed in the genus '' Alauda''. The current genus name, ''Melanocorypha'' is from Ancient Greek ''melas'', "black", and ''koruphos'' a term used by ancient writers for a now unknown bird, but here confused with ''korudos'', "lark". "Calandra"' derives ultimately from ''kalandros'' the Ancient Greek name for this bird. The bimaculated lark is also sometimes termed as the calandra lark. Subspecies Four subspecies are recognized: * Western calandra lark (''M. c. calandra'') - (Linnaeus, 1766): Found in southern Europe and north-western Africa to Turkey (except south-central and south-eastern Turkey), Transcaucasia and north-western Iran * Eastern calandra ...
