Dataset Abstract:

We surveyed 13 sites in primary forest within the Tapajos National Forest in November 1999.
At each site we dug two soil pits and collected cores of known volume from the surface and at 10, 30 and 50 cm depth. Along a 250 m transect 10 m wide we recorded for all stems over 10 cm DBH: species, height, and diameter. We measured LAI along the transect at 26 points with a LICOR LAI-2000. We collected canopy foliage with a shotgun at dawn, and recorded leaf water potential with a pressure chamber. Samples of foliage, wood, bark, fine roots and litter were analysed for %N, %C and delta 13C, and delta 15N at CENA. Soils were analysed for $C, %N, texture and water content at EMBRAPA Belem.

=========================================================================================================================

Data Application and Derivation:

The goal of this study was to quantify heterogeneity in soil and vegetation characteristics at the fine scale to better understand potential implications they could have with respect to carbon cycling and productivity across multiple scales of interest.

Quality Assessment (Data Quality Attribute Accuracy Report):

Quality Assessment:

Species identifications were done to the best of their abilities by local workers familiar with the region but no samples were sent to herbaria for confirmation



The LAI-2000 assumes a random distribution of leaves and cannot distinguish leaf area from non-leaf area (stems and branches); which can lead to a slight positive bias while the increased weight of the outermost annular ring in the software has been shown to cause a negative bias estimated at 8% (LeBlanc and Chen 2001).



In the soils analysis precision of both the organic carbon method and the total nitrogen method is estimated at less than or equal to 2% while the precision of the pipette method for soil texture analysis is calculated to be 5%. Internal working standards were included in every run as standard laboratory procedure.



Stable isotope ratios of carbon and nitrogen were measured relative to international recognized standards. Internal working standards (Atropine and soil standard no. 502-308 from LECO Corporation) were included in every run, as regular laboratory procedure. The precision of measurements was plus or minus 0.3 %, 0.1 %, 0.25 per mil and 0.35 per mil for C, N, delta 13C and delta 15N, respectively

Process Description:

Data Acquisition Materials and Methods:

Samples were collected from sites within the Tapajos National Forest located approximately 50 km south of Santarem, Para.



Site Information:

The locations of the 13 sites are as follows:

Site Latitude Longitude

1 Lat S: 2 degrees 50\' 17.1 Long W: 54 degrees 58\' 9.6

2 Lat S: 2 degrees 50\' 25.5 Long W: 54 degrees 58\' 41.6

3 Lat S: 2 degrees 52\' 26.1 Long W: 54 degrees 57\' 5.6

4 Lat S: 2 degrees 51\' 31.7 Long W: 54 degrees 57\' 22.2

(Sites 1-4 are near km 67 camp)



5 Lat S: 3 degrees 21\' 22.8 Long W: 54 degrees 56\' 47.7

6 Lat S: 3 degrees 21\' 3.6 Long W: 54 degrees 56\' 57.3

7 Lat S: 3 degrees 22\' 50.9 Long W: 54 degrees 54\' 41.2

8 Lat S: 3 degrees 22\' 33.3 Long W: 54 degrees 54\' 37.7

(Sites 5-8 are near km 177 camp)



9 Lat S: 4 degrees 02\' 52.0 Long W: 54 degrees 56\' 27.6

10 Lat S: 4 degrees 02\' 28.6 Long W: 54 degrees 54\' 28.5

(Sites 9-10 are near Ruropolis)



11 Lat S: 3 degrees 29\' 20.2 Long W: 55 degrees 15\' 24.6

12 Lat S: 3 degrees 22\' 4.2 Long W: 55 degrees 12\' 35.4

13 Lat S: 3 degrees 24\' 31.7 Long W: 55 degrees 13\' 22.5

(Sites 11-13 are accessed from the Tapajos river)



Field methods:

At each site, we marked out a transect 250m long and 10 m wide. Transects were oriented away from the entry direction and perpendicular to any access trail and/or nearby river, and thus away from likely sources of disturbance. Each transect was divided into five equally sized subplots with a length of 50 m.



Soils:

At each site we dug two soil pits 60 cm deep and collected cores of known volume from the surface and at 10, 30 and 50 cm depth. The soil corer was 46.3 mm in diameter and 50 mm in length.



Vegetation:

Along a 250 m transect 10 m wide we recorded for all stems over 10 cm DBH: species, height, and diameter. Species identification was done by the local mateiro to the best of his ability. We measured leaf area index (LAI) along the transect at 26 points with a LICOR LAI-2000. We collected canopy foliage with a shotgun at dawn, and recorded leaf water potential (LWP)with a PMS-600 pressure chamber.





Lab methods:

Samples of foliage, wood, bark, fine roots and litter were analyzed for percent N, percent C and delta 13C, and delta 15N at on a Finigan Delta Plus at CENA.

Soils were analyzed for percent C, percent N, texture and water content at EMBRAPA Belem. Soil organic carbon was determined using a potassium dichromate oxidation method followed by tirtation with Mohr\'s salt. Soil total nitrogen was determined via Kjeldhal digest followed by a treatment with alkaline solution which releases all nitrogen in the sample solution as ammonium. Ammonium is then captured and quantified via diffusion chamber. Soil texture was determined using the pipette method.



Allometric equations:

Stem biomass was calculated using two different equations



The first developed by INPE

Biomass is equal to exp(-2.409+ 0.952* ln(dbh^2*height*0.55))



And the second reported in Laurance et al 1999

Biomass is equal to 600 (exp{3.323 plus (2.456(ln(d/100)))})
