Xerapoa
''Xerapoa'' is a genus of land planarians from Brazil. Description The genus ''Xerapoa'' includes small-sized land planarians with subcylindrical body and anterior end raised. Usually the sensory pits of the anterior region open at the tip of small papillae. The ovaries are located more posteriorly in the body, close to the pharynx, when compared to other genera of the subfamily Geoplaninae, in which the ovaries are closer to the anterior end. The creeping sole is considerably thin, occupying about one third of the ventral side. Etymology The name ''Xerapoa'' comes from Tupi ''xerapoa'' (sharp-pointed), referring to the spiny aspect of the anterior end in species with sensorial papillae. Species The genus ''Xerapoa'' includes four described species: *'' Xerapoa hystrix'' Froehlich, 1955 *'' Xerapoa pseudorhynchodemus'' (Riester, 1938) *'' Xerapoa trina'' (Marcus Marcus, Markus, Márkus or Mărcuș may refer to: * Marcus (name), a masculine given name * Marcus (praenome ...

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 ...

Claudio Gilberto Froehlich
Claudio Gilberto Froehlich (born 10 June 1927) is a Brazilian zoologist.Neglected ScienceClaudio Gilberto Froehlich Retrieved 19 February 2017. Life Froehlich was born in 1927 in São Paulo, Brazil. In 1951 he started his doctoral studies at the Universidade de São Paulo together with Eudóxia Maria de Oliveira Pinto, who later would become his wife. They both had Ernst Marcus as their advisor. Marcus suggested that they should work on the taxonomy of land planarians since it was a poorly studied but highly diverse group in the region. Later, in 1960, he received his post-doctoral degree from Lund University. After his first academic years studying land planarians, Froehlich started to work with freshwater invertebrates, especially stoneflies.Entomologistas do BrasilClaudio Gilberto Froehlich.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Land Planarian
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 ...

Ovary
The ovary is an organ in the female reproductive system that produces an ovum. When released, this travels down the fallopian tube into the uterus, where it may become fertilized by a sperm. There is an ovary () found on each side of the body. The ovaries also secrete hormones that play a role in the menstrual cycle and fertility. The ovary progresses through many stages beginning in the prenatal period through menopause. It is also an endocrine gland because of the various hormones that it secretes. Structure The ovaries are considered the female gonads. Each ovary is whitish in color and located alongside the lateral wall of the uterus in a region called the ovarian fossa. The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size.Daftary, Shirish; Chakravarti, Sudip (2011). Manual of Obstetrics, 3rd Edition. Elsevier. pp. 1-16. . ...

Tupi Language
Old Tupi, Ancient Tupi or Classical Tupi (also spelled as Tupí) is an extinct Tupian language which was spoken by the aboriginal Tupi people of Brazil, mostly those who inhabited coastal regions in South and Southeast Brazil. It belongs to the Tupi–Guarani language family, and has a written history spanning the 16th, 17th, and early 18th centuries. In the early colonial period, Tupi was used as a '' lingua franca'' throughout Brazil by Europeans and aboriginal Americans, and had literary usage, but it was later suppressed almost to extinction. Today, only one modern descendant is living, the Nheengatu language. The names Old Tupi or classical Tupi are used for the language in English and by modern scholars (it is referred to as in Portuguese), but native speakers called it variously "the good language", "common language", "human language", in Old Tupi, or, in Portuguese, "general language", "Amazonian general language", "Brazilian language".

Ernst Marcus (zoologist)
Ernst Gustav Gotthelf Marcus (8 June 1893 – 30 June 1968) was a German zoologist, former occupant of the chair of zoology at the University of São Paulo from 1936 to 1963, and co-founder of the Oceanographic Institute of the University of São Paulo. Life Marcus was born in Berlin in a Jewish family, the son of Georg Marcus, a jurist, and Regina Schwartz. As a child, he lived near the Berlin Zoo, where he observed all kinds of animals, and collected beetles. He studied at the Kaiser Friedrich Gymnasium and later entered the Friedrich Wilhelm University to study zoology. He began his doctoral studies in the Entomology Department at the Berlin Museum and, in 1914, he published his first zoological work. However, his studies were later delayed due to World War I, where he fought as a soldier, and his second work, a thesis on Coleoptera, was published only in 1919, when he received his doctorate. After graduation, he continued to work at the museum and was assigned to the Bryozoa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
