Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fern
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaf, leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled Fiddlehead fern, fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae (plant), Polypodiidae) and eusporangiate ferns, the latter group including horsetails, Psilotaceae, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspleniaceae
The Aspleniaceae (spleenworts) are a family of ferns, included in the order Polypodiales. The composition and classification of the family have been subject to considerable changes. In particular, there is a narrow circumscription, Aspleniaceae s.s. (adopted here), in which the family contains only two genera, and a very broad one, Aspleniaceae s.l., in which the family includes 10 other families kept separate in the narrow circumscription, with the Aspleniaceae s.s. being reduced to the subfamily Asplenioideae. The family has a worldwide distribution, with many species in both temperate and tropical areas. Elongated unpaired sori are an important characteristic of most members of the family. Description Members of the family grow from rhizomes, that are either creeping or somewhat erect, and are usually but not always unbranched, and have scales that usually have a lattice-like (clathrate) structure. In some species, for example '' Asplenium nidus'', the rhizomes form a kind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biobío Region
The Biobío Region ( ) is one of Chile's sixteen regions (first-order administrative divisions). With a population of 1.5 million, thus being the third most populated region in Chile, it is divided into three provinces: Arauco, Biobío and Concepción. The latter contains its capital and largest city, Concepción, a major city and metro area in the country. Los Ángeles, capital of the Biobío Province, is another important city in the region. Geography The Region of the Biobío is bordered on the west by the Pacific Ocean, on the east by Argentina, on the north by the Chilean Ñuble Region, and on the south by the Araucanía Region. The Region has been hit by many Chilean earthquakes, including the most powerful earthquake ever recorded (in 1960) and the great earthquake of 2010. Many communities in the region were greatly affected by the earthquake of 2010 and the subsequent tsunami. That earthquake damaged Talcahuano and Dichato; the tsunami destroyed much of wh ...

Flora Of Argentina
The environment of Argentina is highly biodiverse. Biodiversity Flora Subtropical plants dominate the Gran Chaco in the north, with the '' Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant are the wacho white and black algarrobo trees ('' Prosopis alba'' and ''Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. In Argentina forest cover is around 10% of the total land area, equivalent to 28,573,000 hectares (ha) of forest in 2020, down from 35,204,000 ha in 1990. In 2020, naturally regenerating forest covered 27,137,000 ha and planted forest covered 1,436,000 ha. Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 7% o ...

Flora Of Chile
The native flora of Chile is characterized by a higher degree of endemism and relatively fewer species compared to the flora of other countries of South America. A classification of this flora necessitates its division into at least three general zones: the desert provinces of the north, Central Chile, and the humid regions of the south. Northern Chile The first is an arid desert(Atacama desert) absolutely barren along part of the coast, between Arica and Copiapó, but with a coarse scanty vegetation near the Cordilleras along watercourses and on the slopes where moisture from the melting snows above percolates through the sand. The altiplano of the northernmost portion of the Chilean territory is home to the '' Browningia candelaris'', a candelabrum-shaped cactus. Another cactus species, the '' Echinopsis atacamensis'', grows in the pre-Andean area. The high Andean region is also characterized by the presence of species of the genus '' Polylepis'' and the '' Azorella compacta ...
