Figures S1 to S5

Introduction

This supporting information provides a breakdown of the data presented in

Figures 1 to 5 of the paper. Each figure provides data per site (Figure S1) or per

plot (S2 to S5).

Figure S1. Seasonality of weather variables in four lowland Amazonian forests sites in

Peru, Bolivia and Brazil. Weather stations were located at Allpahuayo (ALP-01, black

square), Caxiuanã (CAX-06, grey circle), Kenia (KEN-01, grey triangle), Tambopata

(TAM-05, grey diamond), and Tanguro (TAN-05, grey circle). Solar irradiance (W m-

2), precipitation (mm mo-1), air temperature (ºC) and relative humidity (%) are

presented on a monthly timescale, as a mean over three years (2009-2011)

Figure S2. Seasonality of net primary productivity components in nine lowland

Amazonian forest plots in Peru, Bolivia and Brazil. Data are separated between dry

sites (KEN-02, KEN-01, TAN-05, and TAN-06) (a, c, e) and humid sites (CAX-03,

CAX-06, CAX-08, TAM-05, and TAM-06) (b, d, f). Net primary productivity of leaf

(NPPLeaf), above-ground coarse wood (NPPACW) and fine roots (NPPRoots) are presented

for each plot on a monthly timescale, as a mean over three (2009-2011) or four (2009-

2012, Tambopata) years. The start and end of the dry season is represented by vertical

grey lines. Solid lines represent the average of four plots.

Figure S3. Seasonality of canopy net primary productivity in seven lowland

Amazonian forest plots in Peru, Bolivia and Brazil. Data are separated between dry

sites (KEN-02, KEN-01, TAN-05, and TAN-06) (a, c, e) and humid sites (CAX-03,

CAX-06, CAX-08, TAM-05, and TAM-06) (b, d, f). Net primary productivity of leaf

(NPPLeaf), flower (NPPFlower) and fruit (NPPFruit) are presented for each plot on a

monthly timescale, as a mean over three (2009-2011) or four (2009-2012, Tambopata)

years. Canopy components were not separated into leaves, flowers and fruit in

Tanguro. Solid lines represent the average of four plots.

Figure S4. Seasonality of net primary productivity allocation to canopy (NPPCanopy),

above-ground coarse wood (NPPACW) and fine roots (NPPRoots) in eight lowland

Amazonian forest plots, Peru, Bolivia and Brazil. Data are separated between dry sites

(KEN-02, KEN-01, TAN-05, and TAN-06) (a, c, e) and humid sites (ALP-01, ALP-

30, CAX-03, CAX-06, CAX-08, TAM-05, and TAM-06) (b, d, f). Allocation data are

presented as percentage of total NPP allocated to each component each month, as a

mean over three (2009-2011) or four (2009-2012, Tambopata) years. Solid lines

represent the average of four plots.

Figure S5. Ternary diagrams of seasonal allocation of net primary productivity to canopy

(NPPCanopy), above-ground coarse wood (NPPACW) and fine roots (NPPRoots) in seven

lowland Amazonian forest plots, Peru, Bolivia and Brazil. Data are provided for dry sites

(KEN-02, KEN-01, TAN-05, and TAN-06), and humid sites (CAX-03, CAX-06, CAX-08,

TAM-05, and TAM-06). Each point represents the percentage of total NPP allocated to

each component each month, as a mean over three (2009-2011) or four (2009-2012,

Tambopata) years. We did not have sufficient seasonal data from Allpahuayo to carry out

this analysis. Circles represent dry season months (May to September), triangles represent

wet season months.
