Nicholas Miklouho-Maclay
Nicholas Miklouho-Maclay (russian: Никола́й Никола́евич Миклу́хо-Макла́й; 1846 – 1888) was a Russian Imperial explorer. He worked as an ethnologist, anthropologist and biologist who became famous as one of the earliest scientists to settle among and study indigenous people of New Guinea who had never seen a European.Webster, E. M. (1984). ''The Moon Man: A Biography of Nikolai Miklouho-Maclay''. University of California Press, Berkeley. 421 pages. Miklouho-Maclay spent the major part of his life travelling and conducted scientific research in the Middle East, Australia, New Guinea, Melanesia and Polynesia. Australia became his adopted country and Sydney the hometown of his family.Wongar, B., Commentary and Translator's Note in Miklouho-Maclay, N. N.

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] |
Calcareous Sponge
The calcareous sponges of class Calcarea are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate in the form of calcite or aragonite. While the spicules in most species have three points, in some species they have either two or four points. Biology All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans are represented within class Calcarea : asconoid, syconoid, and leuconoid. Typically, calcareous sponges are small, measuring less than in height, and drab in colour. However, a few brightly coloured species are also known. Calcareous sponges vary from radially symmetrical vase-shaped body types to colonies made up of a meshwork of thin tubes, or irregular massive forms. The skeleton has either a mesh or honeycomb structure. Classifica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guanches
The Guanches were the indigenous inhabitants of the Canary Islands in the Atlantic Ocean some west of Africa. It is believed that they may have arrived on the archipelago some time in the first millennium BCE. The Guanches were the only native people known to have lived in the Macaronesian archipelago region before the arrival of Europeans, as there is no accepted evidence that the other Macaronesian archipelagos (the Cape Verde Islands, Madeira and the Azores) were inhabited. After the Spanish conquest of the Canaries starting in the early 15th century, many natives were wiped out by the Spanish settlers while others interbred with the settler population, although elements of their culture survive within Canarian customs and traditions, such as Silbo (the whistled language of La Gomera Island). In 2017, the first genome-wide data from the Guanches confirmed a North African origin and that they were genetically most similar to ancient North African Berber peoples of the ...

Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous special territory of the European Union. The seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animals Described In 1868
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echino ...

Fauna Of Russia
The wildlife of Russia inhabits terrain that extends across 12 time zones and from the tundra region in the far north to the Caucasus Mountains and prairies in the south, including temperate forests which cover 70% of the country's territory. Russia's forests comprise 22% of the forest in the world as well as 33% of all temperate forest in the world. According to the data furnished in the ''Red Data Book of the Russian Federation'', as of 1996, there were 266 mammal species and 780 bird species under protection. Some of the threatened plant species are the Siberian cedar pine, Korean cedar pine in the far eastern part of the country, wild chestnut in the Caucasus. In the Russian Far East the mammals reported are brown bears, Eurasian lynx, and red deer, Amur tigers, Amur leopards, and Asiatic black bears. There are also about 350 bird species and 30 percent of all endangered species in Russia are found here which include 48 unique endangered species. Carnivores under threat incl ...
