Journal ArticleDOI
Charcoal and smoke extract stimulate the soil microbial community in a highly weathered xanthic Ferralsol
TL;DR: In this paper, the influence of charcoal and smoke condensates (pyroligneous acid, PA) on microbial activity in a highly weathered Amazonian upland soil was assessed via measurements of basal respiration (BR), substrate-induced respiration, and exponential population increase after substrate addition.
Journal ArticleDOI
Atmospheric versus biological sources of polycyclic aromatic hydrocarbons (PAHs) in a tropical rain forest environment
Martin Krauss,Wolfgang Wilcke,Christopher Martius,Adelmar G. Bandeira,Marcos Garcia,Wulf Amelung +5 more
TL;DR: The occurrence of Naphthalene, PHEN, and PERY in plants, termite nests, and soils at elevated concentrations supports the assumption of their biological origin.
Journal ArticleDOI
Litter fall, litter stocks and decomposition rates in rainforest and agroforestry sites in central Amazonia
TL;DR: In this article, the sustainability of agroforestry systems in Amazonia was assessed from their litter dynamics and decomposition, and litter stocks were determined from July 1997 to March 1999 in four sites in central Amazonia: a primary rainforest, a 13-year-old secondary forest, and two sites of a polyculture forestry system which consisted of four planted tree species of commercial use.
Journal ArticleDOI
Effects of three pesticides on the avoidance behavior of earthworms in laboratory tests performed under temperate and tropical conditions.
TL;DR: It was investigated whether three pesticides relevant for the Brazilian Amazon (benomyl, carbendazim, lambda-cyhalothrin) affect the avoidance behavior of the earthworm Eisenia fetida and results indicate that this test gives reproducible and reliable results.
Journal ArticleDOI
Structure and function of soil fauna communities in Amazonian anthropogenic and natural ecosystems
Hubert Höfer,Werner Hanagarth,Marcos Garcia,Christopher Martius,Elizabeth Franklin,Jörg Römbke,Ludwig Beck +6 more
TL;DR: The soil biological conditions of two 5-year-old polyculture tree plantations in Amazonia were studied comparatively to a 13-year old secondary forest and a nearby undisturbed primary forest.
