Amaurospiza Moesta - Blackish-blue Seedeater (male)
''Amaurospiza'' is a genus of birds in the cardinal family Cardinalidae. Taxonomy and species list The genus ''Amaurospiza '' was introduced by the German ornithologist Jean Cabanis in 1861 with Cabanis's seedeater as the type species. The name is derived from the Ancient Greek ''amauros'', meaning "dusky", and (), a catch-all term for ''finch''-like birds. This genus was formerly included in the tanager family Thraupidae. It was moved to the cardinal family Cardinalidae based on a molecular phylogenetic study published in 2007. The genus contains four species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ...: References Seedeaters Bird genera Taxonomy articles created by Polbot {{Passeroidea-stub ...

Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. Cabanis was born in Berlin to an old Huguenot family who had moved from France. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, returning in 1841 with a large natural history collection. He was assistant and later director of the Natural History Museum of Berlin (which was at the time the Berlin University Museum), taking over from Martin Lichtenstein. He founded the ''Journal für Ornithologie'' in 1853, editing it for the next forty-one years, when he was succeeded by his son-in-law Anton Reichenow. He died in Friedrichshagen. A number of birds are named after him, including Cabanis's bunting ''Emberiza cabanisi'', Cabanis's spinetail ''Synallaxis cabanisi'', Azure-rumped tanager The azure-rumped tanager or Cabanis's tanager (''Poecilostreptus cabanisi'') is a species of bird in the family Thraupidae.

Cabanis's Seedeater
The Cabanis's seedeater (''Amaurospiza concolor'') is a species of bird in the cardinal family Cardinalidae that the International Ornithological Committee (IOC) accepted as a species in 2015. (But see the taxonomy section below.) It is found southern Mexico and Central America. Taxonomy and systematics In 2015 the IOC split the subspecies ''Amaurospiza concolor aequatorialis'' from the blue seedeater (''Amaurospiza concolor'' sensu lato) as the Ecuadorean seedeater (''Amaurospiza aequatorialis'') and renamed ''A. concolor'' Cabanis's seedeater. The decision was based on a molecular phylogenetic study published in 2014. However, the South American Classification Committee of the American Ornithological Society (AOS) had previously rejected the split, and as of May 2021 the AOS North American Committee has not considered it and the Clements taxonomy has not adopted it.Remsen, J.

Carrizal Seedeater
The Carrizal seedeater (''Amaurospiza carrizalensis'') is a species of bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is endemic to Venezuela. Taxonomy and systematics The Carrizal seedeater was described based on three specimens collected in 2001. The researchers who determined that it was a new species, Miguel Lentino and Robin L. Restall, named it Carrizal blue seedeater, but the "blue" was dropped by taxonomic organizations to avoid conflict with what was then the blue seedeater (''Amaurospiza concolor'').Remsen, J.

Blackish-blue Seedeater
The blackish-blue seedeater (''Amaurospiza moesta'') is a species of bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found in Argentina, Brazil, and Paraguay. Taxonomy and systematics The blackish-blue seedeater is monotypic. It and the other members of genus ''Amaurospiza'' were traditionally placed in family Emberizidae. (At that time, the family included the New World sparrows, which are now in their own family Passerellidae.) Since approximately 2008 they have been placed in their current family.Remsen, J.

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 so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuadorian Seedeater
The Ecuadorian seedeater (''Amaurospiza aequatorialis'') is a species of bird in the cardinal family Cardinalidae that the International Ornithological Committee (IOC) accepted as a species in 2015. (But see the taxonomy section below.) It is found in the Andes in southwestern Colombia through Ecuador to northern Peru. Taxonomy and systematics The Ecuadorian seedeater was formally described in 1888 by the English ornithologist Richard Bowdler Sharpe based on specimens collected in Ecuador. He coined the binomial name ''Amaurospiza aequatorialis''. The specific epithet is Late Latin for "equatorial", a name commonly used for species from Ecuador, ''ecuador'' means "equator" in Spanish. In 2015 the IOC split the subspecies ''Amaurospiza concolor aequatorialis'' from the blue seedeater (''Amaurospiza concolor'' sensu lato) as the Ecuadorian seedeater (''Amaurospiza aequatorialis'') and renamed ''A. concolor'' Cabanis's seedeater.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.
