LBA-ECO ND-04 Termite Mound and Soil Characterization, Amazonas, Brazil: 1999-2001

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.

本数据集详尽报告了位于巴西亚马孙州马瑙斯市联邦公路BR 174公里53号处，Embrapa研究站内的Distrito Agropecuario da SUFRAMA地区，对筑丘白蚁的综合研究的结果。研究区域涵盖了原生森林地点、相邻的7-8年次生森林地点，以及两个被用于农林业用途的废弃牧场地点。所报道内容包括：（1）筑丘白蚁物种的分布及其丘体面积丰度，（2）对丘体土壤微生物群落、根生物量、幼苗出土成功率、土壤呼吸、氮矿化作用等进行表征，（3）对白蚁丘体土壤的物理、化学和水利性质进行描述。同时，对相邻对照土壤样品也进行了分析，以进行比较。本数据集包含15个逗号分隔的数据文件。
