Leaf trait variation on Erythroxylum tortuosum (Erythroxylaceae) and its relationship with oviposition preference and stress by a host-specific leaf miner
(Wiley-Blackwell, 2011-04-01)
It has been suggested that plant physical and chemical traits vary considerably in space and time. Hence, leaf-mining insects may adjust their oviposition in response to leaf attributes representing high quality. Moreover, ...
Non-labile plant C contributes to long-lasting macroaggregation of an Oxisol
(2013-03-01)
Decomposition of plant material influences soil aggregation dynamics in ways that are still poorly understood, especially for Oxisols, in which oxides are believed to play a dominant role. In an incubation experiment, we ...
Influence of the mineral content of the seston on tropical cladocerans of a marginal lake.
(2010-01-01)
Bioassays were carried out seasonally to evaluate individual growth and reproduction of cladocerans, from a marginal lake, with the addition of nitrogen (N), phosphorus (P), and both N and P to natural seston; Methods: ...
AMMONIUM AND NITRATE IN SOIL AND RATOON SUGARCANE GROWN IN FUNCTION OF NITROGEN ON OXISOL
(2013-01-01)
After harvest, sugarcane residues left on the soil surface can alter nitrogen (N) dynamics in the plant-soil system. In Oxisols, the nitrogen fertilizer applied had its effects on the levels of ammonium and nitrate in the ...
