Armadillidium Maniatum
''Armadillidium maniatum'' is a European species of woodlouse endemic to Greece. Taxonomy ''Armadilliidum maniatum'' was described in 2006, based on only 3 specimens (2 males and 1 female) that were collected in a beach of southern Peloponnese during May 1980. Description ''Armadillidium maniatum'' is a medium to large sized species, reaching maximum dimensions of about 17 x 8.7 mm. Its tergites are completely smooth and the body lacks pigmentation, except for the eyes, which are black, and the hind margins of the pereion-tergites, which bear dark stripes. The frontal shield doesn't surpass the anterior edge of the head, distinctly bends backwards and tightly fits to the frontal part of the head. The secondary antennae have a conspicuously enlarged third segment, trapezoidal lobes and flagellum articles of equal length. The hind margins of the first pair of epimera are deeply and sharply angled. The telson is wider than long, has straight sides and a rounded tip. Concernin ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleopod
The anatomy of a decapod consists of 20 body segments grouped into two main body parts: the cephalothorax and the pleon (abdomen). Each segment – often called a somite – may possess one pair of appendages, although in various groups these may be reduced or missing. Cephalothorax Head # antennules # antennae # mandibles # first maxillae # second maxillae The head also bears the (usually stalked) compound eyes. The distal portion of a mandible or maxilla which has a sensory function is known as a palp. Thorax / pereon #first maxillipeds #second maxillipeds #third maxillipeds #first pereiopods #second pereiopods #third pereiopods #fourth pereiopods #fifth pereiopods Maxillipeds are appendages modified to function as mouthparts. Particularly in the less advanced decapods, these can be very similar to the pereiopods. Pereiopods are primarily walking legs and are also used for gathering food. They are also the ten legs from which decapods take their name. Those pereiopods which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodlice
Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects. Woodlice evolved from marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. This makes them quite unique among the crustaceans, being one of the few lineages to have transitioned into a fully terrestrial environment. Woodlice have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments like those of the genus ''Ligia''. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape (:wiktionary:conglobate, conglobate) as a defensive mechanism or to conserve moisture; others have partial rolling ability, but most cannot ...

Littoral Zone
The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore. In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely flood, inundated), to coastal areas that are permanently underwater, submerged — known as the ''foreshore'' — and the terms are often used interchangeably. However, the geographical meaning of ''littoral zone'' extends well beyond the intertidal zone to include all neritic waters within the bounds of continental shelves. Etymology The word ''littoral'' may be used both as a noun and as an adjective. It derives from the Latin language, Latin noun ''litus, litoris'', meaning "shore". (The doubled ''t'' is a late-medieval innovation, and the word is sometimes seen in the more classical-looking spelling ''litoral''.) Description The term has no single definition. What is regarded as the full extent of the littoral zone, and the way the littora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armadillidium Album
''Armadillidium album'', also known as the beach pill woodlouse, is a species of isopod within the family Armadillidiidae. The species is salt tolerant,Wim Vader, Lein De Wolf, Biotope and biology of Armadillidium album Dollfuss, a terrestrial isopod of sandy beaches, in the SW Netherlands, Netherlands Journal of Sea Research, Volume 22, Issue 2, 1988, Pages 175-183, ISSN 0077-7579, . inhabiting coastal sand dunes and saltmarshes within Europe. They can sometimes be found under driftwood or burrowed within grains of sand of which their colour pattern mimics.

Troglofauna and stygofauna are the two types of subterranean fauna. Both are associated with hypogeal habitats – troglofauna is associated with terrestrial subterranean environment (caves and underground spaces above the water table), and stygofauna with all kind of subterranean waters (groundwater, aquifers, subterranean rivers, dripping bowls, gours, etc.). Environment Subterranean fauna is found worldwide and includes representatives of many animal groups, mostly arthropods and other invertebrates. However, there is a number of vertebrates (such as cavefishes and cave salamanders), although they are less common. Because of the complexity in exploring underground environments, many subterranean species are yet to be dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mani Peninsula
The Mani Peninsula (), also long known by its medieval name Maina or Maïna (), is a geographical and cultural region in the Peloponnese of Southern Greece and home to the Maniots (), who claim descent from the ancient Spartans. The capital city of Mani is Areopoli. Mani is the central of three peninsulas which extend southwards from the Peloponnese. To the east is the Laconian Gulf, to the west the Messenian Gulf. The Mani peninsula forms a continuation of the Taygetos mountain range, the western spine of the Peloponnese. Etymology There are many theories regarding the etymology of the word Mani. The most accepted one is that it represents the natural evolution of the medieval name of the region, which was Maini, of uncertain origin. The name "Mani" may come from the name of the Frankish castle ''le Grand Magne''. Geography The terrain is mountainous and inaccessible. Until recent years many Mani villages could be reached only by sea. Today a narrow and winding road ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vatheia
Vatheia ( ; also ''Vathia'') is a village on the Mani Peninsula, in south-eastern Laconia. The local community of Vatheia is named after this village. The aforementioned local community is a subdivision of the municipal unit of Oitylo. It is known for its tower-houses built on a hill dominating the surrounding countryside. Vatheia is linked by road north to Areopoli and Kalamata and south to Cape Matapan also known as Tenaro. In the northern and eastern direction, the southern reaches of the Sangias mountain range overlook the village. Farmland and maquis shrubland cover the hill slopes. On the hills and mountain sides around Vatheia proper are clusters of abandoned houses, towers and chapels known as the perichora, meaning environs. Currently, Vatheia is a tourist attraction during spring and summer due to the abundance of wild flowers that cover the nearby hills and its scenic views. Moreover, it is an iconic example of the south Maniot vernacular architecture as it developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Series
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is al ...

Seta
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, Scale (insect anatomy), scales, or Common name, informally, hairs. The setal membrane is not Cuticle, cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (the group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemos ...
