Cephaloflexa Araucariana
''Cephaloflexa araucariana'' is a species of land planarian in the subfamily Geoplaninae found in Brazil. Description ''Cephaloflexa araucariana'' is a small to medium-sized land planarian up to in length when crawling. The dorsum is bluish-gray with two lateral black bands. The venter is dark gray, becoming black near the margins. The anterior end is narrow and rolled upwards by a retractor muscle. The numerous eyes are distributed marginally along the whole body, except for the apex of the anterior end, where they are absent. Distribution The only known place of occurrence of ''C. araucariana'' is the São Francisco de Paula National Forest The São Francisco de Paula National Forest ( pt, Floresta Nacional de São Francisco de Paula) is a national forest in the state of Rio Grande do Sul, Brazil. Origins Decree law 3.124 of 19 March 1941 created the National Pine Institute (Insti ... in southern Brazil. References {{Taxonbar, from=Q2275298 Geoplanidae Inve ...

Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...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 ...

Geoplaninae
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. However, one species, ''Obama nungara'' has been introduced in Europe. Description The subfamily Geoplaninae was initially defined by Ogren and Kawakatsu (1990)Ogren, R. E. and Kawakatsu, M. (1990). ''Index to the species of the family Geoplanidae (Turbellaria, Tricladida, Terricola) Part I: Geoplaninae.'' Bulletin of Fujis Women's College. 29: 79-166. for land planarians which have a broad creeping sole, mouth in the second half of the body, dorsal testes, subepithelial longitudinal musculature well developed and parenchymal longitudinal musculature absent or not well developed. The eyes contour the anterior region in a single row and posteriorly form several rows, which may spread onto the dorsum, and extend to the posterior end of the body. However, most, if not all, of these characteristics are not exclusive and cannot be considered a synapomorphy of the group. Some characteristics have also been ...

São Francisco De Paula National Forest
The São Francisco de Paula National Forest ( pt, Floresta Nacional de São Francisco de Paula) is a national forest in the state of Rio Grande do Sul, Brazil. Origins Decree law 3.124 of 19 March 1941 created the National Pine Institute (Instituto Nacional do Pinho), a federal agency concerned with pine trees. Among its duties it created what would become the national forests of the south and south-east of Brazil. By ordinance 561 of 25 October 1968 these became the forest parks of the National Pine Institute, and were classed as national forests under the Forest Code of 1965. Location The São Francisco de Paula National Forest is in the Atlantic Forest biome. It has an area of . It is located in the municipality of São Francisco de Paula, Rio Grande do Sul. *Altitudes range from . *Average annual rainfall is . *Average temperature is . The National Pine Institute planted zones of reforestation with exotic species. Half the area is native Atlantic forest. More than 20 en ...
