Response of Arbuscular Mycorrhizal Fungi and Soil Chemical Properties to Brachiaria decumbens Grass Production Technologies

HIGHLIGHTS Brachiaria decumbens pasture associated with kudzu Pueraria phaseloides legume represents an alternative for higher arbuscular mycorrhizal fungi (AMF). Higher lime doses presented high rates of AMF and improved soil chemical properties (SCP). Higher lime doses were the most influential te...

Diversidad de macro-invertebrados en sistemas silvopastoriles del sur de Quintana Roo, México

Rev. biol. trop; 67 (6), 2019
La diversidad de macro-invertebrados está relacionada con el estado de conservación del suelo, no obstante, la remoción de la cubierta vegetal natural para el establecimiento de sistemas ganaderos extensivos afecta su integridad. Una estrategia para la conservación de estos organismos es la implement...

El impacto de la hidroquinona usada como un modelo de efector redox sobre la desnitrificación potencial, la actividad microbiana y las condiciones redox de un suelo cultivable

Rev. argent. microbiol; 47 (3), 2015
In this microcosm study, we analyzed the effect produced by hydroquinone on the expression of soil biological denitrification, in relation to the redox state of the soil, both in terms of intensity factor (Eh′) and capacity factor (amount of oxidized or reduced compounds). The supplementation of an...

Application of the Soil and Water Assessment Tool (SWAT Model) on a small tropical island (Great River Watershed, Jamaica) as a tool in Integrated Watershed and Coastal Zone Management

Rev. biol. trop; 62 (supl.3), 2014
The Great River Watershed, located in north-west Jamaica, is critical for development, particularly for housing, tourism, agriculture, and mining. It is a source of sediment and nutrient loading to the coastal environment including the Montego Bay Marine Park. We produced a modeling framework using the S...

Estructura de la comunidad y distribución vertical de la macrofauna de fondos blandos en isla Gorgona, Pacífico Colombiano

Rev. biol. trop; 62 (supl.1), 2014
Soft bottoms are important in marine ecosystems but their ecology have been less studied in the tropics than in temperate areas. This article describes the temporal, spatial, and vertical distribution of the community structure of subtidal soft bottom macrofauna on Isla Gorgona, Colombian Pacific. Sample...
