Pseudoseisura Cursor
The cacholotes are four species of relatively large, heavy-billed furnariids in the genus ''Pseudoseisura''. They are found in shrubby habitats in the South American countries of Brazil, Bolivia, Argentina, Paraguay and Uruguay. They are essentially brown (ranging from deep rufous to pale gray-brown depending on species), and all are crested to some extent. Taxonomy The genus ''Pseudoseisura'' was introduced in 1853 by the German naturalist Ludwig Reichenbach to accommodate the white-throated cacholote. The name combines the Ancient Greek ''pseudos'' meaning "false" and ''seisoura'', a bird mentioned by the Greek lexicologist Hesychius of Alexandria and believed to be a wagtail ''Motacilla''. Species The genus contains four extant species: The allopatric Caatinga and gray-crested cacholotes were formerly considered conspecific under the name rufous cacholote (''Pseudoseisura cristata'').

Brown Cacholote
The brown cacholote (''Pseudoseisura lophotes'') is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Taxonomy and systematics The brown cacholote's taxonomy is unsettled. The International Ornithological Committee and BirdLife International's ''Handbook of the Birds of the World'' assign it two subspecies, the nominate ''P. l. lophotes'' (Reichenbach, 1853) and ''P. l. argentina'' ( Parkes, 1960).HBW and BirdLife International (2022) Handbook of the Birds of the World and BirdLife International digital checklist of the birds of the world.

Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the Capital city, capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay River, Paraguay and Paraná River, Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway. Spanish conquistadores arrived in 1524, and in 1537, they established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Reductions, Jesuit missions, where the native Guaraní people were converted to Ch ...

Pleistocene
The Pleistocene ( , often referred to as the '' Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the t ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allopatric
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information between th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wagtail
Wagtails are a group of passerine birds that form the genus ''Motacilla'' in the family Motacillidae. The forest wagtail belongs to the monotypic genus ''Dendronanthus'' which is closely related to ''Motacilla'' and sometimes included therein. The common name and genus names are derived from their characteristic tail pumping behaviour. Together with the pipits and longclaws they form the family Motacillidae. The willie wagtail (''Rhipidura leucophrys'') of Australia is an unrelated bird similar in coloration and shape to the Japanese wagtail. It belongs to the fantails. Taxonomy The genus ''Motacilla'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. The type species is the white wagtail. ''Motacilla'' is the Latin name for the pied wagtail; although actually a diminutive of ''motare'', "to move about", from medieval times it led to the misunderstanding of ''cilla'' as "tail".

Hesychius Of Alexandria
Hesychius of Alexandria ( grc, Ἡσύχιος ὁ Ἀλεξανδρεύς, Hēsýchios ho Alexandreús, lit=Hesychios the Alexandrian) was a Greek grammarian who, probably in the 5th or 6th century AD,E. Dickey, Ancient Greek Scholarship (2007) p. 88. compiled the richest lexicon of unusual and obscure Greek words that has survived, probably by absorbing the works of earlier lexicographers. The work, titled "Alphabetical Collection of All Words" (, ''Synagōgē Pasōn Lexeōn kata Stoicheion''), includes more than 50,000 entries, a copious list of peculiar words, forms and phrases, with an explanation of their meaning, and often with a reference to the author who used them or to the district of Greece where they were current. Hence, the book is of great value to the student of the Ancient Greek dialects and in the restoration of the text of the classical authors generallyparticularly of such writers as Aeschylus and Theocritus, who used many unusual words. Hesychius is importa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
