The Impact of Competition and Allelopathy on the Trade-Off between Plant Defense and Growth in Two Contrasting Tree Species
In contrast to plant-animal interactions, the conceptual framework regarding the impact of secondary metabolites in mediating plant-plant interference is currently less well defined. Here, we address hypotheses about the role of chemically-mediated plant-plant interference (i.e., allelopathy) as a driver of Mediterranean forest dynamics. Growth and defense abilities of a pioneer (Pinus halepens...
متن کاملCompetition induces allelopathy but suppresses growth and anti-herbivore defence in a chemically rich seaweed.
Many seaweeds and terrestrial plants induce chemical defences in response to herbivory, but whether they induce chemical defences against competitors (allelopathy) remains poorly understood. We evaluated whether two tropical seaweeds induce allelopathy in response to competition with a reef-building coral. We also assessed the effects of competition on seaweed growth and seaweed chemical defenc...
متن کاملIs Allelopathic Activity of Ipomoea murucoides Induced by Xylophage Damage?
Herbivory activates the synthesis of allelochemicals that can mediate plant-plant interactions. There is an inverse relationship between the activity of xylophages and the abundance of epiphytes on Ipomoea murucoides. Xylophagy may modify the branch chemical constitution, which also affects the liberation of allelochemicals with defense and allelopathic properties. We evaluated the bark chemica...
متن کاملBiological bulletin virtual symposium: the neuroecology of chemical defense.
In 2006, The Biological Bulletin initiated the idea of publishing “virtual symposia,” a series of papers, in a single issue, on a compelling theme that is central to the scope of this journal. The inaugural virtual symposium, on marine invertebrate models of learning and memory, was introduced in an article by McPhie and Miller (2006). Here, we present the second chapter, focusing on “The Neuro...
متن کاملAllelopathy an Environmentally Friendly Method for Weed Control
Biological weed management is a system that incorporates the use of diverse biological organisms and biologically-based approaches including allelopathy, crop competition, and other cultural practices to significantly reduce weed densities in a manner that is similar to use of chemical herbicides alone. Interest in developing effective biological weed management systems continues to increase be...
