LBA-ECO LC-14 Specific Leaf Area and Phenology, km 67 Site, Para, Brazil: 2001-2006

This data set provides measurements of specific leaf area and monthly phenological observations for selected tree and vine species at the km 67 Seca Floresta site, Tapajos National Forest, Para, Brazil. The study site was part of a rainfall exclusion experiment that was conducted from 1999-2006 to develop an understanding of the physical processes driving the observed soil water dynamics at the site.

Phenological observations were made from 2001-2004 in rainfall exclusion and control plots. In total, 3,224 leaves were observed across 223 individuals and 56 species. The phenological observations included the month and year when a given leaf was first observed fully expanded and last observed alive.

Starting in July 2004 and continuing through January 2006, leaves that had been followed in the phenology study were sampled and leaf area and mass were determined and the specific leaf area was calculated.

There are two comma-delimited data files with this data set.

本数据集提供了位于巴西帕拉州塔帕约斯国家公园67公里处Seca Floresta地点，针对选定树木和葡萄品种的特定叶片面积以及月度物候观测数据。研究地点曾是1999年至2006年进行的降雨排除实验的一部分，旨在探究该地点土壤水分动态变化的驱动物理过程。物候观测自2001年至2004年在降雨排除和处理对照区域进行。总计对223个个体和56个物种的3,224片叶子进行了观测。物候观测记录了特定叶片首次完全展开和最后一次被观测到仍存活的月份及年份。自2004年7月开始，直至2006年1月，对物候研究中追踪的叶片进行了采样，测定了叶片面积和重量，并计算了特定叶片面积。本数据集包含两个以逗号分隔的文件。
