Araucaria Angustifolia
''Araucaria angustifolia'', the Paraná pine, Brazilian pine or candelabra tree (, or ), is a critically endangered species in the Pinophyta, conifer genus ''Araucaria''. Although the common names in various languages refer to the species as a "pine", it does not belong in the genus ''Pinus''. Description It is an evergreen tree usually growing to tall and diameter at breast height. The tree is fast growing; as much as in 14 years in a Tree plantation, plantation at Puerto Piray, Misiones Province, Argentina. CAB Direct (database), CABD]19600603436 The leaves are thick, tough and scale like, triangular, long, broad at the base, and with razor-sharp edges and tip. They persist 10 to 15 years, so cover most of the tree except for the trunk and older branches. The bark is uncommonly thick, up to 15 cm (6 in) deep. The inner bark and resin from the trunk of the tree is reddish. It is usually Plant sexuality, dioecious, with the male and female conifer cone, cones on separa ...

Aparados Da Serra National Park
The Aparados da Serra National Park () is a National park (Brazil), national park located in the Serra Geral range of Rio Grande do Sul and Santa Catarina (state), Santa Catarina states in the Southern Region, Brazil, south of Brazil, between 29º07’—29º15’ S and 50º01’—50º10’ W. It was created in 1959 as one of Brazil's first national parks, to protect the Itaimbezinho canyon. It extends over an area of 10,250 hectares and also includes the Fortaleza Canyon, Fortaleza, Malacara, and Índios Coroado Canyons. Geology The geology of the Aparados da Serra da Serra National Park is dominated by the presence of volcanic rocks of the Paraná and Etendeka traps, Paraná-Etendeka Large Igneous Province, which are locally grouped in the Serra Geral Group. This geological group is further divided into four lava formations, namely Torres, Vale do Sol, Palmas, and Esmeralda. Additional rock formations in the area include sedimentary rocks of the Paraná Basin, including the eo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Sexuality
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants ( green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination pr ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from 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 () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

South Region, Brazil
The South Region of Brazil ( ) is one of the five regions of Brazil. It includes the states of Paraná, Rio Grande do Sul, and Santa Catarina, and covers , being the smallest region of the country, occupying only about 6.76% of the territory of Brazil. Its whole area is smaller than that of the state of Minas Gerais, in Southeast Brazil, for example or the whole metropolitan France. It is a tourist, economic and cultural pole. It borders Uruguay, Argentina, and Paraguay, as well as the Centre-West and Southeast regions, and the Atlantic Ocean. The region is considered the safest in Brazil to visit, having a lower crime rate than other regions in the country. History Pre-Columbian history By the time the first European explorers arrived, all parts of the territory were inhabited by semi- nomadic hunter-gatherer native tribes. They subsisted on a combination of hunting, fishing, and gathering. Portuguese colonization European colonization in Southern Brazil started with ...

Northeast Region, Brazil
The Northeast Region of Brazil ( ) is one of the five official and political regions of the country according to the Brazilian Institute of Geography and Statistics. Of Brazil's twenty-six states, it comprises nine: Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe and Bahia, along with the Fernando de Noronha archipelago (formerly a separate territory, now part of Pernambuco). Chiefly known as ''Nordeste'' ("Northeast") in Brazil, this region was the first to be colonized by the Portuguese and other European peoples, playing a crucial role in the country's history. ''Nordestes dialects and rich culture, including its folklore, cuisines, music and literature, became the most easily distinguishable across the country. To this day, ''Nordeste'' is known for its history and culture, as well as for its natural environment and its hot weather. ''Nordeste'' stretches from the Atlantic seaboard in the northeast and southeast, northwest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gondwana
Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia (continent), Australia, Zealandia, Arabian Peninsula, Arabia, and the Indian subcontinent. Gondwana was formed by the Accretion (geology), accretion of several cratons (large stable blocks of the Earth's crust), beginning with the East African Orogeny, the collision of India and Geography of Madagascar, Madagascar with East Africa, and culminating in with the overlapping Brasiliano orogeny, Brasiliano and Kuunga orogeny, Kuunga orogenies, the collision of South America with Africa, and the addition of Australia and Antarctica, respectively. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of some , about one-fifth of the Earth's surface. It fused with Laurasia during the Carboniferous to form Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triassic
The Triassic ( ; sometimes symbolized 🝈) is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.4 Mya. The Triassic is the first and shortest period of the Mesozoic Era and the seventh period of the Phanerozoic Eon. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Araucaria Araucana
''Araucaria araucana'', commonly called the monkey puzzle tree, monkey tail tree, pewen, pehuen pine or piñonero, is an evergreen tree belonging to the family Araucariaceae and growing to a trunk diameter of and a height of . It is native to central and southern Chile and western Argentina. It is the hardiest species in the conifer genus ''Araucaria''. Because of the prevalence of similar species in ancient prehistory, it is sometimes called an animate living fossil, fossil. It is also the list of national trees, official tree of Chile and of the neighboring Argentine province of Neuquén. The IUCN changed its conservation status to Endangered species, Endangered in 2013 as logging, forest fires, and grazing caused its population to dwindle.
