Pseudopaludicola Falcipes
''Pseudopaludicola falcipes'' (Hensel's swamp frog) is a species of frog in the family Leptodactylidae. It is found in the Pampas of northeastern Argentina, Uruguay, and southern Brazil. Description Males measure and females in snout–vent length. It shows extensive variation in patterns of dorsal coloration and in morphology. Phylogeography ''Pseudopaludicola falcipes'' shows a high level of genetic diversity but, contrary to what might expected for a small frog, no significant differentiation across its distribution range. This situation is probably possible because of the homogeneity of its habitat, the Pampean grasslands, large population sizes, and passive mechanisms of dispersal (hydrochory). Molecular data nevertheless suggest that ''Pseudopaludicola falcipes'' is divided into two populations, the larger one in Argentina and Uruguay, and the smaller one in Brazil. These populations are estimated to have separated some 1 million years ago, and become into contact again s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Reinhold Friedrich Hensel
Reinhold is a German male given name. This German name is originally from "Reinold", composed of two elements. The first is from ''ragin'', meaning "the (Germanic) Gods" and ''wald'' meaning "powerful". This name was popularised by the ancient German hero figure known as Reinhold von Montalban (The Four Sons of Aymon), Reinhold von Meilan ( The Dietrich Saga), and ultimately, as Saint Reinhold von Köln. The -h- is recorded in the Dietrich von Bern legendary figure De gude Reinholt van Meilan who was the only one spared the slaughter at Erminrich's castle due to his loyalty to Dietrich. Hence with the addition of the -h- the etymology is interpreted as the emphatic prefix ''regn-'' with ''hold'', apparently meaning "solemnly loyal".George T. Gillespie, A Catalogue Of Persons Named In German Heroic Literature (700-1600) Including Named Animals And Objects And Ethnic Names, 1973, pp 107-108 This name was brought to the British Isles by Viking conquerors, in the form of the Old N ...

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] |
Leptodactylidae
The southern frogs form the Leptodactylidae, a name that comes from Greek meaning a bird or other animal having slender toes. They are a diverse Family (biology), family of frogs that most likely diverged from other hyloidea, hyloids during the Cretaceous. The family has undergone major taxonomic revisions in recent years, including the reclassification of the former subfamily Eleutherodactylinae into its own family the Eleutherodactylidae; the Leptodactylidae now number 206 species in 15 genera distributed throughout Mexico, the Caribbean, and Central America, Central and South America. The family includes terrestrial, burrowing, aquatic, and arboreal members, inhabiting a wide range of habitats. Several of the genera within the Leptodactylidae lay their eggs in foam nests. These can be in crevices, on the surface of water, or on forest floors. These foam nests are some of the most varied among frogs. When eggs hatch in nests on the forest floor, the tadpoles remain within the ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pampas
The Pampas (from the qu, pampa, meaning "plain") are fertile South American low grasslands that cover more than and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos, and Córdoba; all of Uruguay; and Brazil's southernmost state, Rio Grande do Sul. The vast plains are a natural region, interrupted only by the low Ventana and Tandil hills, near Bahía Blanca and Tandil (Argentina), with a height of and , respectively. The climate is temperate, with precipitation of that is more or less evenly distributed throughout the year, making the soils appropriate for agriculture. The area is also one of the distinct physiography provinces of the larger Paraná–Paraguay plain division. Topography This region has generally low elevations, whose highest levels do not exceed 600 metres (1,970 feet) in altitude. The coastal areas and most of the Buenos Aires Province are predominantly plain (with some wetlands) and the interior areas (mainly in the sou ...

Pseudopaludicola Falcipes02
''Pseudopaludicola'' is a genus of leptodactylid frogs from lowland northern and central South America. They are known under the common name dwarf swamp frogs or swamp frogs. Systematics ''Pseudopaludicola'' are small frogs, growing maximally to in snout–vent length. The synapomorphy defining this genus is the greatly enlarged tubercle on the outer edge of the forearm (i.e., hypertrophied antebrachial tubercle). Genetic analyses have recovered this genus as monophyletic, in accordance with earlier studies using morphological characters. Genetic data suggest four major clades within the genus. Species Following the Amphibian Species of the World, there are currently 25 species in this genus: AmphibiaWeb also lists ''Pseudopaludicola serrana'', whereas the Amphibian Species of the World considers it synonym of ''Pseudopaludicola murundu ''Pseudopaludicola'' is a genus of leptodactylid frogs from lowland northern and central South America.

Hydrochory
In Spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living ( biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit. However, this simplified view may ignor ...

Genetic Admixture
Genetic admixture occurs when previously diverged or isolated genetic lineages mix.⅝ Admixture results in the introduction of new genetic lineages into a population. Examples Climatic cycles facilitate genetic admixture in cold periods and genetic diversification in warm periods. Natural flooding can cause genetic admixture within populations of migrating fish species. Genetic admixture may have an important role for the success of populations that colonise a new area and interbreed with individuals of native populations. Mapping Admixture mapping is a method of gene mapping that uses a population of mixed ancestry (an admixed population) to find the genetic loci that contribute to differences in diseases or other phenotypes found between the different ancestral populations. The method is best applied to populations with recent admixture from two populations that were previously genetically isolated. The method attempts to correlate the degree of ancestry near a genetic locus w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudopaludicola Restinga
''Pseudopaludicola restinga'' is a species of amphibian in the family Leptodactylidae, which is found in the coastal region of Espírito Santo, Brazil. It can be differentiated from the other species of the genus ''Pseudopaludicola'' by a number of factors, such as its size, body shape, vocalization pattern, and number of chromosomes. Males have an average length between 11 and 14 millimeters, and females between 14 and 16 millimeters. Males vocalize during the night, right after long rains, with calls consisting of two pulses. It was described on May 16, 2018, by a group of five researchers in the scientific journal PeerJ. Although it is only being described now, there were already reports of the species since 2011, where it was treated as ''Pseudopaludicola falcipes'' species ''affinis''. Its specific epithet derives from the Portuguese word ''restinga'', which designates the biome where it is found. It may be threatened by the creation of ports and by oil and natural gas ex ...
