Dendropsophus Nanus
''Dendropsophus nanus'' (common name: dwarf treefrog) is a species of frog in the family Hylidae. It is found in northern Argentina, Paraguay, Uruguay, eastern Bolivia, Brazil, French Guiana, and Suriname. It is very common frog occurring in many habitat types and adapting well to anthropogenic disturbance. It inhabits herbaceous vegetation at the edge of standing water. Breeding takes place in temporary waterbodies. The diet of Argentinean ''Dendropsophus nanus'' was found to consist mostly of dipterans and spiders. During the cold periods, these frogs partly rely on their fat reserves, more so than sympatric '' Hypsiboas pulchellus''.

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Hypsiboas Pulchellus
The Montevideo tree frog (''Boana pulchella'') is a species of frog in the family Hylidae found in eastern, central, and northern Argentina, south-eastern Brazil, south-eastern Paraguay, and Uruguay. It is a common species occurring in open habitats in forests, grasslands, and flooded savannas. Breeding takes place in permanent ponds and flooded grasslands. The diet of Argentinean ''Boana pulchella'' was found to consist mostly of spiders, dipterans and, crickets. During the cold time of the year, these frogs continue to feed at high rate, instead of partly relying on their fat reserves as the sympatric ''Dendropsophus nanus ''Dendropsophus nanus'' (common name: dwarf treefrog) is a species of frog in the family Hylidae.

Amphibians Described In 1889
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Sympatric
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do no ...
