    Description: The vast extent of the Amazon Basin has historically restricted the study of its tree communities to the local and regional scales. Here, we provide empirical data on the commonness, rarity, and richness of lowland tree species across the entire Amazon Basin and Guiana Shield (Amazonia), collected in 1170 tree plots in all major forest types. Extrapolations suggest that Amazonia harbors roughly 16,000 tree species, of which just 227 (1.4%) account for half of all trees. Most of these are habitat specialists and only dominant in one or two regions of the basin. We discuss some implications of the finding that a small group of species--less diverse than the North American tree flora--accounts for half of the world's most diverse tree community.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉ter Steege, Hans -- Pitman, Nigel C A -- Sabatier, Daniel -- Baraloto, Christopher -- Salomao, Rafael P -- Guevara, Juan Ernesto -- Phillips, Oliver L -- Castilho, Carolina V -- Magnusson, William E -- Molino, Jean-Francois -- Monteagudo, Abel -- Nunez Vargas, Percy -- Montero, Juan Carlos -- Feldpausch, Ted R -- Coronado, Euridice N Honorio -- Killeen, Tim J -- Mostacedo, Bonifacio -- Vasquez, Rodolfo -- Assis, Rafael L -- Terborgh, John -- Wittmann, Florian -- Andrade, Ana -- Laurance, William F -- Laurance, Susan G W -- Marimon, Beatriz S -- Marimon, Ben-Hur Jr -- Guimaraes Vieira, Ima Celia -- Amaral, Ieda Leao -- Brienen, Roel -- Castellanos, Hernan -- Cardenas Lopez, Dairon -- Duivenvoorden, Joost F -- Mogollon, Hugo F -- Matos, Francisca Dionizia de Almeida -- Davila, Nallarett -- Garcia-Villacorta, Roosevelt -- Stevenson Diaz, Pablo Roberto -- Costa, Flavia -- Emilio, Thaise -- Levis, Carolina -- Schietti, Juliana -- Souza, Priscila -- Alonso, Alfonso -- Dallmeier, Francisco -- Montoya, Alvaro Javier Duque -- Fernandez Piedade, Maria Teresa -- Araujo-Murakami, Alejandro -- Arroyo, Luzmila -- Gribel, Rogerio -- Fine, Paul V A -- Peres, Carlos A -- Toledo, Marisol -- Aymard C, Gerardo A -- Baker, Tim R -- Ceron, Carlos -- Engel, Julien -- Henkel, Terry W -- Maas, Paul -- Petronelli, Pascal -- Stropp, Juliana -- Zartman, Charles Eugene -- Daly, Doug -- Neill, David -- Silveira, Marcos -- Paredes, Marcos Rios -- Chave, Jerome -- Lima Filho, Diogenes de Andrade -- Jorgensen, Peter Moller -- Fuentes, Alfredo -- Schongart, Jochen -- Cornejo Valverde, Fernando -- Di Fiore, Anthony -- Jimenez, Eliana M -- Penuela Mora, Maria Cristina -- Phillips, Juan Fernando -- Rivas, Gonzalo -- van Andel, Tinde R -- von Hildebrand, Patricio -- Hoffman, Bruce -- Zent, Eglee L -- Malhi, Yadvinder -- Prieto, Adriana -- Rudas, Agustin -- Ruschell, Ademir R -- Silva, Natalino -- Vos, Vincent -- Zent, Stanford -- Oliveira, Alexandre A -- Schutz, Angela Cano -- Gonzales, Therany -- Trindade Nascimento, Marcelo -- Ramirez-Angulo, Hirma -- Sierra, Rodrigo -- Tirado, Milton -- Umana Medina, Maria Natalia -- van der Heijden, Geertje -- Vela, Cesar I A -- Vilanova Torre, Emilio -- Vriesendorp, Corine -- Wang, Ophelia -- Young, Kenneth R -- Baider, Claudia -- Balslev, Henrik -- Ferreira, Cid -- Mesones, Italo -- Torres-Lezama, Armando -- Urrego Giraldo, Ligia Estela -- Zagt, Roderick -- Alexiades, Miguel N -- Hernandez, Lionel -- Huamantupa-Chuquimaco, Isau -- Milliken, William -- Palacios Cuenca, Walter -- Pauletto, Daniela -- Valderrama Sandoval, Elvis -- Valenzuela Gamarra, Luis -- Dexter, Kyle G -- Feeley, Ken -- Lopez-Gonzalez, Gabriela -- Silman, Miles R -- New York, N.Y. -- Science. 2013 Oct 18;342(6156):1243092. doi: 10.1126/science.1243092.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Naturalis Biodiversity Center, Leiden, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24136971" target="_blank"〉PubMed〈/a〉

    Description: The high alpha-diversity of tropical forests has been amply documented, but beta-diversity-how species composition changes with distance-has seldom been studied. We present quantitative estimates of beta-diversity for tropical trees by comparing species composition of plots in lowland terra firme forest in Panama, Ecuador, and Peru. We compare observations with predictions derived from a neutral model in which habitat is uniform and only dispersal and speciation influence species turnover. We find that beta-diversity is higher in Panama than in western Amazonia and that patterns in both areas are inconsistent with the neutral model. In Panama, habitat variation appears to increase species turnover relative to Amazonia, where unexpectedly low turnover over great distances suggests that population densities of some species are bounded by as yet unidentified processes. At intermediate scales in both regions, observations can be matched by theory, suggesting that dispersal limitation, with speciation, influences species turnover.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Condit, Richard -- Pitman, Nigel -- Leigh, Egbert G Jr -- Chave, Jerome -- Terborgh, John -- Foster, Robin B -- Nunez, Percy -- Aguilar, Salomon -- Valencia, Renato -- Villa, Gorky -- Muller-Landau, Helene C -- Losos, Elizabeth -- Hubbell, Stephen P -- New York, N.Y. -- Science. 2002 Jan 25;295(5555):666-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Tropical Forest Science, Smithsonian Tropical Research Institute, Unit 0948, APO AA 34002-0948, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11809969" target="_blank"〉PubMed〈/a〉
