A tissue analysis trial for the diagnosis of boron status was performed during the 2003 growing season in Paine County, Metropolitan Region, Chile. Five-year-old 'Hass' avocado (Persea americana Mill.) trees were soil ...
Plant quality vs. risk of parasitism: Within-plant distribution and performance of the corn leaf aphid, Rhopalosiphum maidis
(2001)
1. Colonies of the aphid Rhopalosiphum maidis on Johnsongrass, Sorghum halepense, usually occur inside the whorl. The present work assessed the role of two biotic factors, plant quality and parasitism by Lysiphlebus ...

Why are there few seedlings beneath the myrmecophyte Triplaris americana?
(2007)
We compared the relative importance of chemical alellopathy, pruning behaviour of resident ants and other non-related agents to ant-plant mutualism for seedling establishment beneath TriplaTiS americana L. (Polygonaceae), ...
