Aiouea macedoana is a species of plant in the family Lauraceae. It is endemic to Brazil.
Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" after a period of apparent absence.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
The flowering plant family Lauraceae, the laurels, includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide. They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as Sassafras, are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus Cassytha is unique in the Lauraceae in that its members are parasitic vines.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.

Aiouea obscura is a species of plant in the family Lauraceae endemic to Costa Rica. The species occurs on the southern Pacific slopes, south-east of Palmar north.
Mezilaurus is a genus of plant in the family Lauraceae. It is a neotropical genus consisting of 18-27 species, mostly hardwood evergreen trees, occurring from Costa Rica to the southeast of Brazil. 13 species have been identified in Brazil, distributed mostly in the Amazon region. In Rio de Janeiro state only M. navalium (Allemão) Taub. ex Mez has been recorded. Some species have been reported within the Cerrado and in semideciduous forest surrounding the Pantanal Matogrossense. The name Mezilaurus refers to its similar appearance to the genus Laurus.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
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.
Aiouea guatemalensis is a plant species in the family Lauraceae. It is endemic to Guatemala where it has only been found in the departments of Petén, Alta Verapaz and Izabal. It is a tree or shrub of up to 8 m that grows in tall broadleaf forest in association with Orbygnia species.
Aiouea parvissima is a plant species in the family Lauraceae. It is endemic to Guatemala where it has only been found in the departments of Petén and Izabal. It is a tree or shrub of up to 7 m that grows in secondary broadleaf forest in association with Manilkara species.
Klaus Kubitzki is a German botanist. He is an Emeritus professor in the University of Hamburg, at the Herbarium Hamburgense. He is known for his work on the systematics and biogeography of the angiosperms, particularly those of the Neotropics, and also the floristic record of the Tertiary era. His plant systematic work is referred to as the Kubitzki system. He is a member of the American Society of Plant Taxonomists.
Aiouea dubia is a species of tree in the family Lauraceae. It is native to South America.
