​LBA-ECO CD-04 Leaf Photosynthesis and Respiration, Tapajos National Forest: 2000-2006

简介

本数据集报告了以下测量结果：(1) 叶片光合作用响应曲线，该曲线反映了温度、叶龄、变暖、辐射和昼夜节律的影响；(2) 叶片在 30 和 37 摄氏度下的光呼吸速率。测量于 2000 年 6 月至 2006 年 2 月期间在巴西帕拉州塔帕若斯国家森林的 83 公里伐木森林塔、67 公里原始森林塔和塞卡弗洛雷斯塔的对照点进行。该数据集包含 7 个逗号分隔的 ASCII 数据文件。

摘要

File 2: CD04_Photosynthesis_Temp_Curves_Santarem.csv

We made leaf-level measurements at two field sites, working off a 45 m tall scaffold tower at km 67 and a 30 m tall tower at km 83 (Doughty and Goulden, 2008). The specific site for each set of measurements was not provided.

File 3: CD04_Photosynthesis_Warming_30_Santarem.csv

Leaf-level measurements at three field sites, km 67, km 83, and Seca Floresta. The specific site for each set of measurements was not provided.

File 4: CD04_Photosynthesis_Warming_37_Santarem.csv

Leaf-level measurements at three field sites, km 67, km 83, and Seca Floresta. The specific site for each set of measurements was not provided.

File 5: CD04_Photorespiration_Warming_Santarem.csv

Leaf-level measurements at three field sites, km 67, km 83, and Seca Floresta. The specific site for each set of measurements was not provided.

File 6: CD04_Photosynthesis_Subcanopy_Lightcurves_Santarem.csv

Understory species leaf level measurements were made at two field sites, km 67 and km 83. Neither the specific site nor the specific date for sets of measurements were provided.

File 7: CD04_Photosynthesis_Leaf_Age_Santarem.csv

Leaf-level measurements at three field sites, km 67, km 83, and Seca Floresta. The specific site for measurements was not provided.
