DESCRIPTION:Online seminar followed by Q&A – all welcome. NB – all tim
 es given in UK time.\n\nWith over 5.5 million km2\, the Amazon is one of t
 he largest natural ecosystems in our world. The area hosts vast diversity 
 and is also a large carbon store. Recent work showed that while 16\,000 sp
 ecies of trees may inhabit the area\, just 227 (1.4%) of them contribute 5
 0% of all individuals. Over 11\,000 (62%) species have population sizes le
 ss than 1 million individuals and make up less than 0.12% of all individua
 ls of the Amazon. The fact that the area is dominated by so few may simpli
 fy the research into its functioning\, focusing on the hyperdominants but 
 the extreme rarity of so many species makes the study of diversity a chall
 enge. How is this diversity distributed in space and among the angiosperm 
 phylogeny and is there a link with its functioning? Can we predict how the
  Amazon will be affected by global change?\n\nHans is keenly interested in
  the study of plant diversity and mechanisms generating and regulating div
 ersity at regional and local scale with a focus on the Amazon Rainforest. 
 He has built up a large network of collaborating colleagues in the Amazon 
 and outside: The Amazon Tree Diversity Network. This network studies patte
 rns and processes of species composition\, relative abundance patterns\, a
 nd functional behaviour of the Amazon forest\, and its evolution. His prim
 ary inspiration for wanting to work in the Amazon was the Walt Disney’s 
 ‘Wonders of Wilderness’ based on the films ‘True Life Adventures”.
  He started his tropical experience working with epiphytes in forest in Gu
 yana\, climbing canopy trees. After that he lived and worked for ten years
  in Guyana managing the Tropenbos Guyana Programme and doing his PhD resea
 rch. After leaving Guyana\, he concentrated on patterns of diversity in th
 e greater Amazon\, and initiated the Amazon Tree Diversity Network in ~200
 3\, now over 200 persons strong. From 2001 – 2012 he mostly worked at th
 e Utrecht University and in 2012 I moved to Naturalis Biodiversity Center\
 , the Dutch National Natural History Museum.\nSpeakers:\nProf Dr Hans ter 
 Steege (Naturalis)
