Abstract
Abstract: This study conducts a biogeographical review of Aniba in Brazil, including its actual and potential distribution, and a review on the species conservation status. The potential distribution of each Aniba species was modeled using the Brazilian Plants and Fungi Biogeography system, which is interconnected with the SpeciesLink network. A consensus model based on up to five algorithms was used to model the potential distribution of each species. The endemism, conservation status and rarity of each species in Brazil were also analyzed. A total of 3059 records of 30 Brazilian Aniba species were found. In total, 16.1% of the records were excluded because of the lack of valid names, and 53.4% were excluded because of the lack of georeference and name of the person who identified the record. The consensus model showed good results for species with 20 or more pixels. The other species had many errors, and their models could only be used to determine new areas for collections. Nine species were endemic to Brazil, and only three species showed no indicator of rarity. The geographical distribution of Brazilian Aniba species shows a predominantly Amazonian pattern. Only four species are not actually found in the Amazon. Some Amazonian species may also be found in Atlantic Forest areas, and many other species have the potential to live there. Our results indicate that only three species have no conservation problems, whereas 14 species have conservation problems, and 13 other species require further population studies to be best evaluated.
Highlights
IntroductionIt encompasses 92 registered species, with 96, 125 and 99 valid names in the Index Kewensis, The Plant List and TROPICOS, respectively
A total of 30 Aniba species were identified in the Brazilian territory; 48 valid synonyms were found for 19 of those species, and no synonyms were found for 11 species (Table 1)
3,538 Aniba records were found in Brazil, 479 of which were pre-excluded because they were only identified to the genus level
Summary
It encompasses 92 registered species, with 96, 125 and 99 valid names in the Index Kewensis, The Plant List and TROPICOS, respectively. The Aniba species are concentrated in the South American region and are rarely found in Central America and the Antilles (Quinet 2005, Barbosa et al 2012). Central Amazon and Guyana forests are considered dispersal centers of the genus (Kubitzki & Renner 1982). Aniba species are commonly known as laurel, with many variations, mainly according to their odors, colors, exudates and similarities with other species: pichurim bean, oleander, cayenne rosewood, bois de sassafras, moena and itauba. The Tupi Indians referred to laurel plants in general as “ajuva”, “aijuba” and “aniuba” (Pio-Corrêa 1926-1978)
