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 ...

Ploceidae
Ploceidae is a family of small passerine birds, many of which are called weavers, weaverbirds, weaver finches and bishops. These names come from the nests of intricately woven vegetation created by birds in this family. In most recent classifications, Ploceidae is a clade, which excludes some birds that have historically been placed in the family, such as some of the sparrows, but which includes the monotypic subfamily Amblyospizinae. The family is believed to have originated in the mid-Miocene. All birds of the Ploceidae are native to the Old World, most in Africa south of the Sahara, though a few live in tropical areas of Asia. A few species have been introduced outside their native range. Taxonomy and systematics The family Ploceidae was introduced (as Ploceïdes) by the Swedish zoologist Carl Jakob Sundevall in 1836. Phylogenetic studies have shown that the family is sister to a clade containing the families Viduidae and Estrildidae Their common ancestor lived in the middl ...

São Tomé Island
São Tomé Island, at , is the largest island of São Tomé and Príncipe and is home in May 2018 to about 193,380 or 96% of the nation's population. The island is divided into six districts. It is located 2 km (1¼ miles) north of the equator. Geography São Tomé Island is about long (north-south) by wide (east-west). It rises to at Pico de São Tomé and includes the capital city, São Tomé, on the northeast coast. The nearest city on mainland Africa is the port city of Port Gentil in Gabon located to the east. The island is surrounded by a number of small islands, including Ilhéu das Rolas, Ilhéu das Cabras and Ilhéu Gabado. Languages The main language is Portuguese, but there are many speakers of Forro and Angolar (Ngola), two Portuguese-based creole languages. The name "Sao Tome" is Portuguese for "Saint Thomas." Geology The entire island of São Tomé is a massive shield volcano that rises from the floor of the Atlantic Ocean, over below sea lev ...

Euplectes
''Euplectes'' is a genus of passerine bird in the weaver family, Ploceidae. It contains the bishops and widowbirds. They are all native to Africa south of the Sahara. It is believed that all birds in the genus are probably polygynous. The genus ''Euplectes'' was introduced by the English naturalist William John Swainson in 1829 with the southern red bishop as the type species. The name combines the Ancient Greek ''eu'' "fine" or "good" and the New Latin ''plectes'' "weaver". When choosing their mates, females within this genus will often choose males with longer tail lengths, even in species with comparatively shorter tail lengths. Species The genus contains 17 species. Aviculture The yellow-crowned bishop and northern red bishop are popular in aviculture Aviculture is the practice of keeping and breeding birds, especially of wild birds in captivity. Types There are various reasons that people get involved in aviculture. Some people breed birds to preserve a specie ...

Birds Of The Gulf Of Guinea
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Taxa Named By Johann Friedrich Gmelin
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ...
