Sphaenorhynchus Mirim
''Sphaenorhynchus mirim'' is a frog. Scientists have seen it in one place: Fazenda Gemada in Brazil. The adult male frog measures 15.7–18.2 mm in snout-vent length. The frog's head is wider than it is long. The skin of the dorsum is bright green in color with white spots. Parts of the toes are yellow in color. The ventrum and vocal sac are whitish green. Some reports indicate that this frog may undergo early sexual maturation. Scientists note that the tadpoles develop reproductive organs before undergoing metamorphosis. Scientists think this is so they can reproduce soon after becoming frogs. The authors of the original description note that the rest of the tadpoles' bodies develop at the normal rate, making it unlikely that the development observed in their study was due to exposure to pharmaceutical pollutants. This frog is sympatric to '' Dendropsophus elegans'', '' Dendropsophus minutus'', and ''Scinax alter ''Scinax alter'', the Crubixa snouted treefrog, i ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fazenda Gemada
A ''fazenda'' () is a plantation found throughout Brazil during the colonial period (16th - 18th centuries). They were concentrated primarily in the northeastern region, where sugar was produced in the ''engenhos'', expanding during the 19th century in the southeastern region to coffee production. Nowadays ''fazenda'' denotes any kind of farm in Brazilian Portuguese and occasionally in other Portuguese varieties as well. ''Fazendas'' created major export commodities for Brazilian trade, but also led to intensification of slavery in Brazil. Coffee provided a new basis for agricultural expansion in southern Brazil. In the provinces of Rio de Janeiro and then São Paulo, coffee estates, or ''fazendas'', began to spread toward the interior as new lands were opened. By 1850 coffee made up more than 50% of Brazil's exports, which amounted to more than half of the world's coffee production. Along with the expansion of coffee growing came an intensification of slavery as the coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazil
Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo. The federation is composed of the union of the 26 States of Brazil, states and the Federal District (Brazil), Federal District.

Sexual Maturity
Sexual maturity is the capability of an organism to reproduce. In humans it might be considered synonymous with adulthood, but here puberty is the name for the process of biological sexual maturation, while adulthood is based on cultural definitions. Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so. Also, certain cues may trigger an organism to become sexually mature. They may be external, such as drought (certain plants), or internal, such as percentage of body fat (certain animals). (Such internal cues are not to be confused with hormones, which directly produce sexual maturity – the production/release of those hormones is triggered by such cues.) Role of reproductive organs Sexual maturity is brought about by a maturing of the reproductive organs and the production of gametes. It may also be accompanied ...

Reproductive Organ
A sex organ (or reproductive organ) is any part of an animal or plant that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. In animals, the testis in the male, and the ovary in the female, are called the ''primary sex organs''. All others are called ''secondary sex organs'', divided between the external sex organs—the genitals or external genitalia, visible at birth in both sexes—and the internal sex organs. Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs. Terminology The ''primary sex organs'' are the gonads, a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendropsophus Elegans
''Dendropsophus elegans'' is a species of frog in the family Hylidae. It is endemic to Brazil.

Dendropsophus Minutus
''Dendropsophus minutus'' (lesser treefrog) is a species of frog in the family Hylidae. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay, and Venezuela. In Spanish (language), Spanish it is known as ''ranita amarilla común''. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, dry savanna, moist savanna, subtropical or tropical seasonally wet or flooded lowland grassland, intermittent freshwater marshes, pastureland, rural gardens, urban areas, heavily degraded former forest, ponds, and canals and ditches. Scientists have seen it as high as 2000 meters above sea level and as low as at sea level. During the breeding period, the male frogs perch on grass and shrubs near water and on plants mid-water. The male frogs have shown territorial and competitive behavior near preferred perches. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
