5 Distribution of Brazil’s Long-Term Ecological Research (LTER / PELD) sites. Salati & Vose 1984 model

6 The legal Amazon covers an area that is occupied by >100 40.000 km 2 quadrats.

7 Reserva Ducke covers ~100 km 2 of tropical rain forest on the periphery of Manaus.

8 Typical “terra firme” forest, Reserva Ducke.

10 The major “habitat” in the forest is associated with height above the water table.

11 Most species and groups of species appear to be responding mainly to the gradient in depth to water table. Psychotria na Reserva Ducke Kinupp & Magnusson, J. Trop. Ecology 2005 Palmeiras de sub-bosque na Reserva Ducke Costa et al. J Veg Science 2008

12 Example of forest biomass in Reserva Ducke (Carolina Castilho’s data).

13 Relationship between biomass change and soil in replicated integrated plots.

18 The precision of SRTM may restrict modeling using HAND.

19 And the best precision may not be at the elevations most important to organisms.

22 Subtle effects: What happens to aquatic systems in logged areas – data collected by Murilo Dias.

23 Annual production units, Madeira Mil, Itacoatiara.

24 Physico-chemical characteristics of the streams before and 3 months after logging.

25 Composition of the fish community in relation to time since logging.

26 Nectomys lasiurus (rodent): savannas de Alter do Chão. Data: Albertina Lima, Viviane Layme & Bill Magnusson

27 Is the change in frequency of El Niño events sending it to local extinction?

29 We know little about the vegetative biology of fungi, but there reproduction is strongly tied to rainfall. Data source: Ricardo Braga-Neto Relative rainfall Number of species

30 We biologists like to go out and play with organisms.
