Cratera Viridimaculata
''Cratera viridimaculata'' is a species of land planarian found in Argentina. Description ''Cratera viridimaculata'' is a medium-sized land planarian with a lanceolate body, reaching about in length. The color of the dorsum is light olive green covered with dark gray fine spots. The ventral side is whitish and the margins on both dorsal and ventral sides are gray. The several eyes of ''C. viridimaculata'' are distributed marginally in the first millimeters of the body and posteriorly become dorsal, occupying around 30% of the body width just before the region of the pharynx. Etymology The specific epithet ''viridimaculata'' comes from Latin ''viridis'', green + ''maculata'', spotted, and refers to the dorsal pigmentation of the body. Distribution ''Cratera viridimaculata'' is found in the Interior Atlantic Forest, Misiones province, Argentina, an area covered by subtropical forests. It occurs in two natural reserves, Esmeralda Provincial Park The Esmeralda Provincial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geoplanidae
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, ''Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

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) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four ...

Misiones
Misiones (, ''Missions'') is one of the 23 provinces of Argentina, located in the northeastern corner of the country in the Mesopotamia region. It is surrounded by Paraguay to the northwest, Brazil to the north, east and south, and Corrientes Province of Argentina to the southwest. This was an early area of Roman Catholic missionary activity by the Society of Jesus in what was then called the Province of Paraguay, beginning in the early 17th century. In 1984 the ruins of four mission sites in Argentina were designated World Heritage Sites by UNESCO. History Indigenous peoples of various tribes lived in the area of the future province for thousands of years. At the time of European encounter, it was occupied by the Kaingang and Xokleng tribes, later followed by the Guarani tribe. The first European to visit the region, Sebastian Cabot, discovered Apipé Falls while navigating the Paraná River in December 1527. In 1541 Álvar Núñez Cabeza de Vaca reached the Iguazú Fal ...

Esmeralda Provincial Park
The Esmeralda Provincial Park ( es, Parque Provincial Esmeralda) is a provincial park in the Misiones Province of Argentina. Location The Esmeralda Provincial Park is in the department of San Pedro, Misiones. It has an area of . The park is in the Alto Paraná Atlantic forests ecoregion. It is the core of the Yabotí Biosphere Reserve, and protects the Arroyo Yabotí basin. It has rugged terrain with abundant forest. The park contains the Marcio Ayres Biological Station, which is used by scientists studying biodiversity. History The area was established as the Obraje Esmeralda Protected Nature Area by provincial law 2,939 of 1992. It was made a provincial park by law 3.469 on 1997. The park would be part of the proposed Trinational Biodiversity Corridor The Trinational Biodiversity Corridor ( pt, Corredor Trinacional de Biodiversidade) is a proposed ecological corridor that would link protected areas in the Alto Paraná Atlantic forests ecoregion in Brazil, Paraguay and Argen ...

Invertebrates Of Argentina
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'', which ...
