Caracterização física e biológica do solo após aplicação de herbicidas em plantios de acácia-negra (Acacia mearnsii De Wild.) no Rio Grande do Sul
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2008-01-25)
The study of soil quality biological indicators in areas classified as forest production units is important to understand the ecological processes that occur in these systems. Monitoring the soil fauna in modified environments, ...
Reproducibility in the response of soil bacterial community-level physiological profiles from a land use intensification gradient
(Elsevier Science, 2004-05)
This work assessed soil bacterial diversity through community-level physiological profiles (CLPP) over three consecutive years, at sites representing a gradient of land use intensification. The relationship between CLPP ...
Reproductive ecology of the freshwater red alga Batrachospermum delicatulum (Batrachospermales, Rhodophyta) in three tropical streams
(2005-09-01)
Batrachospermum delicatulum specimens from three stream segments were analyzed from a tropical region in south-eastern Brazil (20°18′- 20°49′S, 49°13′-49°46′W). Physical and chemical parameters and the spatial placement ...

On the spatial and temporal dependence of CO2 emission on soil properties in sugarcane (Saccharum spp.) production
(Elsevier B.V., 2015-05-01)
CO2 production in soil is the result of biological processes, such as the decomposition of organic matter and the respiration of roots and soil organisms. It also depends on the physical, chemical and biological properties ...
Spatial variability structure of soil CO2 emission and soil attributes in a sugarcane area
(Elsevier B.V., 2014-05-01)
Soil CO2 emission (F-CO2) is influenced by chemical, physical and biological factors that affect the production of CO2 in the soil and its transport to the atmosphere. F-CO2 varies in time and space depending on environmental ...
