Paraná Flooded Savanna
The Paraná flooded savanna (NT0908) is an ecoregion that borders the southern Paraná River in Argentina. It has largely been converted to agriculture or occupied by urban development, but scattered patches of the original habitat remain along the river. Location The Paraná flooded savanna ecoregion has an area of . It extends along the Paraná River valley from Resistencia, Chaco, south to Buenos Aires. It includes the middle and lower Paraná floodplains, and those of the Paraguay River, a major tributary of the Paraná. In the south it includes the Paraná delta and the basin of the Río de la Plata. The ecoregion consists of a strip of land that runs through the Humid Chaco ecoregion in the north. Further south it runs through the Espinal ecoregion and then the Humid Pampas ecoregion before reaching the Río de la Plata estuary. Physical The region contains wide coastal lowlands, and low islands subject to flooding between the channels of the rivers. The large bodies of ...

Paraná River
The Paraná River ( es, Río Paraná, links=no , pt, Rio Paraná, gn, Ysyry Parana) is a river in south-central South America, running through Brazil, Paraguay, and Argentina for some ."Parana River".

It merges with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean. The first European to go up the Paraná River was the Venetian explorer Sebastian Cabot, in 1526, while working for Spain. A drought hit the river in 2021, causing a 77-year low.

Argentine Swamp Rat
The Argentine swamp rat (''Scapteromys aquaticus'') is a semiaquatic rodent species from South America. It is found in northeastern Argentina and Paraguay, where it lives in freshwater marshes and along the southern coast of the Río de la Plata estuary, as well as in woodland. It is characterized by having stiff hairs on its otherwise naked tail, which are believed to help the animal swim. ''S. aquaticus'' is similar in build to members of the genus ''Rattus''. “ thas a relatively larger head, a stouter body, larger feet, and a relatively longer tail.” The pelage along its back is “long and glossy” varying from brown to dark brown. It can have a grayish wash in some individuals. “The sides have a yellowish cast.” The pelage in the abdominal region is typically an off white color. The forefeet are large for use in swimming and digging. All digits, including the pollex are equipped with a claw. Its karyotype has 2n = 32. Conservation According to the IUCN Red List o ...

Coypu
The nutria (''Myocastor coypus''), also known as the coypu, is a large, herbivorous, semiaquatic rodent. Classified for a long time as the only member of the family Myocastoridae, ''Myocastor'' is now included within Echimyidae, the family of the spiny rats. The nutria lives in burrows alongside stretches of water, and feeds on river plant stems. Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur farmers. Although it is still hunted and trapped for its fur in some regions, its destructive burrowing and feeding habits often bring it into conflict with humans, and it is considered an invasive species. Nutria also transmit various diseases to humans and animals mainly through water contamination. Etymology The genus name ''Myocastor'' derives from the two Ancient Greek words (), meaning "rat, mouse", and (), meaning "beaver". Literally, therefore, the name ''Myocastor'' means ...

Agile Gracile Opossum
The agile gracile opossum (''Gracilinanus agilis''), is an opossum species from South America. It is found in Argentina, Bolivia, Brazil, Colombia, Peru, Paraguay, and Uruguay. It is nocturnal, arboreal and frequents the forest understory, where they use slender branches and vines. Found in evergreen and gallery forests. It is a characteristic inhabitant of the gallery forest of southern South America but has broad habitat tolerance. It has been caught under fallen trunks, in tree holes, and in moist woodland. It is reported to be an adept climber, and nests made of vegetation have been found 1.6 m off the ground. One such nest contained seven individuals. In eastern Paraguay it has usually been captured in vegetation but sometimes has been caught on the ground. This marsupial is found throughout the Brazilian cerrado, usually associated with mesic areas such as gallery forests. This mouse opossum is reported to have up to twelve young. Females lack a true pouch, and the teat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontederia Lanceolata
''Pontederia cordata'', common name pickerelweed (USA) or pickerel weed ( UK), is a monocotyledonous aquatic plant native to the American continents. It grows in a variety of wetlands, including pond and lake margins across an extremely large range from eastern Canada south to Argentina. A few examples include northern rivers, the Everglades and Louisiana. Ecology The species grows as an emergent plant, that is, in flooded conditions, so the plant is generally dependent upon aerenchyma in the stem to carry oxygen into the roots. Its metabolism, is, however, also tolerant of low soil oxygen. It is often found in areas where water levels fluctuate naturally, with spring flooding and later summer emergence. Apart from flooding, the species is also influenced by soil fertility, tending to grow in the more fertile bays of large lakes, for example. Like many aquatic plants, it is negatively affected by salinity and grazing.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservati ...

Typha Domingensis
''Typha domingensis'', known commonly as southern cattail or cumbungi, is a perennial herbaceous plant of the genus '' Typha''. Distribution and habitat It is found throughout temperate and tropical regions worldwide. It is sometimes found as a subdominant associate in mangrove ecosystems such as the Petenes mangroves ecoregion of Yucatán. Uses In the Mesopotamian Marshes of southern Iraq, Khirret is a dessert made from the pollen of this plant. In Turkish folk medicine the female inflorescences of this plant and other ''Typha'' are used externally to treat wounds such as burns. Extracts of ''T. domingensis'' have been demonstrated to have wound healing properties in rat models. Water extracts of the fruit, female flower and male flower of ''Typha domingensis'' exhibit iron chelating activity as well as superoxide and nitric oxide scavenging activities. By contrast, only the fruit and female flower extracts were found to have alpha-glucosidase inhibitory activity. A part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Victoria Cruziana
''Victoria cruziana'' (Santa Cruz water lily, water platter, yrupe, synonym ''Victoria argentina'' Burmeist.) is a tropical species of flowering plant, of the Nymphaeaceae family of water lilies native to South America, primarily Bolivia, Argentina and Paraguay. The plant is a popular water garden plant in botanical gardens where its very large leaves can reach their fullest, up to 2 m wide with a thick rim up to 20 cm high. although rims up to nine inches (23 centimeters) have been recorded. It can be grown in cooler waters than its sister within the genus, the more familiar giant waterlily, ''Victoria amazonica''. A 25 cm diameter flower blooms for two days, arising from the underwater bud, as a white flower that turns to a deep pink on the second and final day of its bloom. ''V. cruziana'' is a thermogenetic or heat-producing plant. The plant prefers to live in colder non moving water and requires warm temperatures in order for the flower to blossom, hence the plant m ...
