Eleutherodactylid
The Eleutherodactylidae are a family of direct-developing frogs native to northern South America, the Caribbean, and southernmost North America. They are sometimes known under the common name rain frogs. Formerly the subfamily Eleutherodactylinae of the family Leptodactylidae, it was raised to the family status following a major revision of New World direct-developing frogs in 2008. As currently defined, the family has more than 200 species (as of 2014, 206 or 207 species). Eleutherodactylid frogs vary considerably in size, from the minuscule ''Eleutherodactylus iberia'' (female snout–vent length ) to the relative giant '' E. inoptatus'' (female snout–vent length ). Except for the ovoviviparous '' E. jasperi'', these frogs have direct development: no free-living tadpole stage exists; instead, eggs develop directly into small froglets. Subfamilies and genera The two subfamilies and four genera are: * Eleutherodactylinae Lutz, 1954 (216 species) ** ''Diasporus'' Hedges, Du ...

Eleutherodactylus Iberia
The Monte Iberia eleuth (''Eleutherodactylus iberia''), also known as the Monte Iberia dwarf frog, is a species of eleutherodactylid frog. It is critically endangered and endemic to rainforest in a small part of easternmost Cuba. It is the smallest frog in the Northern Hemisphere and the third smallest frog in the world, at about in snout–to– vent length (only a few members of the Southern Hemisphere genera '' Brachycephalus'', ''Mini'', ''Paedophryne'' and ''Stumpffia'' are smaller). It was first discovered in 1993 on Mount Iberia in the Holguín Province, from which it gets its name. Much remains unknown about this small creature. It is part of a closely related Cuban group that contains five additional described species ('' E. cubanus'', '' E. etheridgei'', '' E. jaumei'', '' E. limbatus'' and '' E. orientalis'') and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic (at least ''E. iberia'' and ''E. o ...

Eleutherodactylus Inoptatus
''Eleutherodactylus inoptatus'' (common name: Diquini robber frog) is a species of frog in the family Eleutherodactylidae endemic to Hispaniola; it is found both in Haiti and the Dominican Republic. With female snout–vent length of about , it is the largest eleutherodactylid frog. ''Eleutherodactylus inoptatus'' is a common frog found in mesic hardwood forest. It can also live in coffee and banana plantations as long as there are trees and shade. It is impacted by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

Adelophryne
''Adelophryne'' is a genus of frogs in the family Eleutherodactylidae. They are native to northern South America east of the Andes, known roughly from the area corresponding to the Guiana Shield, as well as to the coastal area of Bahia, Brazil. Whether the genus is truly distinct from ''Phyzelaphryne'' remains uncertain. Common name shield frogs has been proposed for this genus, although the stem flea frog is used for some species. Etymology The generic name is derived from the Greek words ''adelos'', meaning "unseen, unknown, obscure", and ''phryne'' for "toad". It refers to the fact that these small frogs were seldom collected until relatively lately. Description ''Adelophryne'' are small leaf-litter frogs. Adults of the largest species, ''A. patamona'', measure no more than in snout–to–vent length and the remaining all are less than . At in males and in females, ''A. michelin'' is not only the smallest in the genus, but among the smallest frogs of the Americas, with on ...

New World direct-developing frogs (Anura: Terrarana): molecular phylogeny, classification, biogeography, and conservation. Zootaxa 1737: 1-182. Many of the 200 species of the genus are commonly known as "rain frogs" or "robber frogs", due to their sharp, high-pitched, insect-like calls. The best-known species is the common coquí (''E. coqui''), which is both a national symbol of Puerto Rico and a notorious invasive species in Hawaii. Two ''Eleutherodactylus'' species, '' E. limbatus'' and '' E. iberia'', are among the smallest known frogs, measuring only 8.5 mm in length (only slightly larger than '' Paedophryne amauensis'', which measures around 7.7 mm). Etymology The name "Eleutherodactylus" is derived from the Greek words for ‘free-toed’, composed of the Ancient Greek ' (, ‘free, unbound’) and ' (, ‘finger, toe’). Most ...

Diasporus
''Diasporus'' is a genus of frogs in the family Eleutherodactylidae. The genus was first described in 2008. They are found in Central and northern South America. They are sometimes referred to as dink frogs, in reference to the "tink" sound that males make during the mating season. Characteristics ''Diasporus'' are small frogs, with a snout–vent length varying between in male '' Diasporus quidditus'' to in female '' Diasporus hylaeformis''. They have a relatively large, distinct head. All members have direct development, skipping a tadpole stage. The male advertisement call is either a "whistle" or a "tink" (or "dink"), depending on the species. Etymology The name is from the Greek ''diaspora'' ("a dispersion from"). It refers to the relationship of this genus to the Caribbean clade A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpol ...

Direct Development
Marine larval ecology is the study of the factors influencing dispersing larvae, which many marine invertebrates and fishes have. Marine animals with a larva typically release many larvae into the water column, where the larvae develop before metamorphosing into adults. Marine larvae can disperse over long distances, although determining the actual distance is challenging, because of their size and the lack of a good tracking method. Knowing dispersal distances is important for managing fisheries, effectively designing marine reserves, and controlling invasive species. Theories on the evolution of a biphasic life history Larval dispersal is one of the most important topics in marine ecology, today. Many marine invertebrates and many fishes have a bi-phasic life cycle with a pelagic larva or pelagic eggs that can be transported over long distances, and a demersal or benthic adult. There are several theories behind why these organisms have evolved this biphasic life history: *L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ovoviviparity
Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop inside eggs that remain in the mother's body until they are ready to hatch. The young of some ovoviviparous amphibians, such as '' Limnonectes larvaepartus'', are born as larvae, and undergo further metamorphosis outside the body of the mother. Members of genera '' Nectophrynoides'' and '' Eleutherodactylus'' bear froglets, not only the hatching, but all the most conspicuous metamorphosis, being completed inside the body of the mother before birth. Among insects that depend on opportunistic exploitation of transient food sources, such as many Sarcophagidae and other carrion flies, and species such as many Calliphoridae, that rely on fresh dung, and parasitoids such as tachinid flies that depend on entering the host as soon as possibl ...

Eleutherodactylus Danae
''Pristimantis danae'' is a species of frog in the family Strabomantidae, sometimes known as Cuzco robber frog. It is found in the Andes between southern Peru and north-western Bolivia. It is named after the daughter of the author, Dana K. Duellman, who helped in collecting the frogs. ''Pristimantis reichlei'', described in 2009, was previously confused with ''Pristimantis danae''. Description Male ''Pristimantis danae'' grow to a snout–vent length of and females to . Body is moderately robust, with head slightly longer than it is wide. The snout is rounded in dorsal view and in profile. The tympanum is prominent. Forearms are slender and hind limbs are limbs long and slender. The fingers and the toes have lateral fringes and bear wide discs; the toes have also basal webbing.

The ventral side is pale yellow, and the hidden surfaces of the thighs are dark brown with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bertha Maria Julia Lutz
Bertha is a female Germanic name, from Old High German ''berhta'' meaning "bright one". It was usually a short form of Anglo Saxon names ''Beorhtgifu'' meaning "bright gift" or ''Beorhtwynn'' meaning "bright joy". The name occurs as a theonym, surviving as Berchta, a figure in Alpine folklore connected to the Wild Hunt, probably an epithet of ''*Frijjō'' in origin. ''Bertha'' appears as a Frankish given name from as early as the 6th century. The monothematic ''Bertha'' as a given name may, however, not originate with the theonym but rather as a short form of dithematic given names including the "bright" element. This is notably the case with the mother of Charlemagne, Bertrada (properly ''berht-rada'' "bright counsel") called "Bertha Broadfoot." Carolingian uses of the name ''Bertha'', as in the case of Bertha, daughter of Charlemagne and Bertha, daughter of Lothair II, are in this tradition. In modern times, the name is associated with an unusually large example of a class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
