LBA-ECO ND-04 TERMITE MOUND AND SOIL CHARACTERIZATION, AMAZONAS, BRAZIL: 1999-20

This data set reports the results of a comprehensive study of mound building termites at the Embrapa research station in the Distrito Agropecuario da SUFRAMA, located at km 53 of the federal highway BR 174 outside Manaus, Amazonas, Brazil. Study areas included a primary forest site, an adjacent 7-8 year old secondary forest site, and two abandoned pasture sites which were being used for agroforest purposes.

Reported are (1) the termite species occurrence and areal abundance of mounds, (2) characterization of the mound soil microbiological community, root biomass, seedling emergence success, soil respiration, nitrogen mineralization, and (3) the characterization of the termite mound soil physical, chemical, and hydraulic properties. Analyses were also performed on samples from adjacent control soils for comparison. This data set contains 15 comma-delimited data files.

本数据集报告了巴西亚马逊州马瑙斯市外联邦公路BR 174的53公里处的SUFRAMA农牧区（Distrito Agropecuario da SUFRAMA）内的巴西农牧业研究公司（Embrapa）研究站中，针对筑冢白蚁（mound building termites）开展的综合研究成果。研究区域涵盖一处原生林样地、一处相邻的7-8年生次生林样地，以及两处正用于农林业生产的废弃牧场样地。

本研究报告了三项核心内容：(1) 白蚁物种发生情况与蚁冢的面积丰度；(2) 蚁冢土壤微生物群落、根系生物量、幼苗出苗成功率、土壤呼吸作用、氮矿化作用的特征表征；(3) 筑冢白蚁蚁冢土壤的物理、化学及水力特性分析。同时还采集了相邻的对照土壤样本开展相关分析以作对比。本数据集包含15个逗号分隔格式的数据文件。
