Stumpffia
''Stumpffia'' is a genus of microhylid frogs that are endemic to Madagascar. They are mostly brown frogs that typically live among leaf litter. ''S. contumelia'' has a snout–vent length of about , making it one of the world's smallest frogs, and several others in the genus are only slightly larger. The largest species is no more than . The majority of the species have only been described since 2010. Each species has a small range and many are seriously threatened. Taxonomy ''Stumpffia'' was first described from the single species '' Stumpffia psologlossa'' Boettger, 1881, based on a single specimen collected on Nosy Be, a large island off the northwest coast of Madagascar, by Antonio Stumpff. By 2017, 15 species were recognised. In late 2017, a major revision of the genus was published. This study used integrative taxonomy, i.e. the combination of multiple different datasets, to delimit and describe new species: it combined morphological, morphometric, chromatic (color) ...

Anilany
''Anilany helenae'' is a species of frog in the microyhlid subfamily Cophylinae. It is the only species in the monotypic genus ''Anilany'', and is endemic to central Madagascar. Taxonomy This species was originally described by Denis Vallan in 2000 as a member of the genus ''Stumpffia''. It was transferred to the genus ''Rhombophryne'' by Peloso et al. in 2016 when they synonymised ''Stumpffia'' with that genus, but was then moved to the newly erected genus ''Anilany'' by Scherz et al. due to its genetic relationships and because it differs significantly in aspects of its morphology (the shape of the vomer, clavicles, and terminal phalanges of the fingers and toes). Habitat and Ecology Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. It now occurs in a few strips of fragmented habitat Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causi ...

Stumpffia Psologlossa
''Stumpffia psologlossa'' is a species of frog in the family Microhylidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forests, plantations, and heavily degraded former forest. It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ....

Andolalao Rakotoarison
Andolalao Rakotoarison (born 1982 in Mahajanga) is a Malagasy herpetologist. Life and research Rakotoarison conducted her Master's thesis at the University of Antananarivo in 2011. She then conducted her PhD at the Technical University of Braunschweig on the systematics of the frogs of the Madagascar-endemic narrow-mouthed frog subfamily Cophylinae, under the supervision of Professor Miguel Vences. As of mid-2020, she has co-authored the description of 52 frog species and two reptiles (one gecko and one chameleon). In particular, Rakotoarison has contributed to knowledge of Madagascar's smallest frogs. In 2017, she led a study published as a monograph with sixteen other coauthors, describing 26 new species of the genus '' Stumpffia'', including several frogs that number among the smallest in the world, and in 2020, she was also involved in the description of five more miniaturised frogs, including the new genus ''Mini'' and its three diminutive species.

Smallest Organisms
The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size. Given the incomplete nature of scientific knowledge, it is possible that the smallest organism is undiscovered. Furthermore, there is some debate over the definition of life, and what entities qualify as organisms; consequently the smallest known organisms (microrganisms) may be nanobes that can be 20 nanometers long. Microorganisms Obligate endosymbiotic bacteria The genome of '' Nasuia deltocephalinicola'', a symbiont of the European pest leafhopper, '' Macrosteles quadripunctulatus'', consists of a circular chromosome of 112,031 base pairs. The genome of '' Nanoarchaeum equitans'' is 491 Kbp nucleotides long. ''Pelagibacter ubique'' '' Pelagibacter ubique'' is one of the smallest known free-living bacteria, with a length of and an average cell diameter of . They also have the smallest free-living bacterium gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhombophryne
''Rhombophryne'' is a genus of Microhylidae, microhylid frogs endemic to Madagascar. It is currently estimated to include more than 23 species, but only 20 of these are currently described. The common name 'diamond frog' has been proposed and used for members of this genus. Taxonomy The genus ''Rhombophryne'' was Monotypic taxon, monotypic until 2005, containing just ''Rhombophryne testudo, R. testudo'' Oskar Boettger, Boettger, 1880. However, in 2005 Andreone et al. showed that the genus ''Plethodontohyla'' was paraphyletic with respect to this genus. Several species were therefore transferred to this genus by Darrel Frost, Frost et al. in 2006, Frank Glaw, Glaw and Miguel Vences, Vences in 2007, and Wollenberg et al. in 2008. In 2015/2016, Peloso et al. re-analysed the genetic relationships of the Microhylidae using partial genomic data. They proposed the synonym (taxonomy), synonymy of ''Stumpffia'' with ''Rhombophryne'' because these genera were found to be paraphyletic. Howev ...

Nosy Be
Nosy Be (; formerly Nossi-bé and Nosse Be, ) is a volcanic island off the northwest coast of Madagascar. Nosy Be is Madagascar's largest and busiest tourist destination. It has an area of , and its population was 109,465 according to the provisional results of the 2018 Census. means "big island" in the Malagasy language. The island was called Assada by the French during the early 17th century. Nosy Be has been given several nicknames over the centuries, including "Nosy Manitra" (the scented island). History The first human inhabitants of Nosy Be were small bands from Antankarana and Zafinofotsy ethnic groups, before the Sakalava people migrated there and became the largest group on the island. These people were joined later by some Comorians, Indians and Antandroy. Nosy Be made its first major appearance in Madagascar's history when King Radama I announced that he intended to conquer the whole west of Madagascar. That plan was eventually achieved in 1837 when the Sakalava ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
