Testing the Unintended Consequences of Lignin Reduction in Genetically Modified Trees on Trophic Interactions
Executive Summary: Genetically modified trees with reduced lignin composition have been proposed as a geoengineering scheme that could potentially reduce environmental impact from chemically harsh pulping practices within the paper industry. Lignin is the complex chemical compound that gives trees their protection against climate, disease, and animal activity. However, the presence of lignin in...
متن کاملTrophic Interactions during Primary Succession: Herbivores Slow a Plant Reinvasion at Mount St. Helens.
Lupines (Lupinus lepidus var. lobbii), the earliest plant colonists of primary successional habitats at Mount St. Helens, were expected to strongly affect successional trajectories through facilitative effects. However, their effects remain localized because initially high rates of reinvasive spread were short lived, despite widespread habitat availability. We experimentally tested whether inse...
متن کاملInfluence of plant genetic diversity on interactions between higher trophic levels.
While the ecological consequences of plant diversity have received much attention, the mechanisms by which intraspecific diversity affects associated communities remains understudied. We report on a field experiment documenting the effects of patch diversity in the plant Baccharis salicifolia (genotypic monocultures versus polycultures of four genotypes), ants (presence versus absence) and thei...
متن کاملPathogenesis, parasitism and mutualism in the trophic space of microbe-plant interactions.
Microbe-host interactions can be categorised as pathogenic, parasitic or mutualistic, but in practice few examples exactly fit these descriptions. New molecular methods are providing insights into the dynamics of microbe-host interactions, with most microbes changing their relationship with their host at different life-cycle stages or in response to changing environmental conditions. Microbes c...
متن کاملEcological and evolutionary consequences of tri-trophic interactions: Spatial variation and effects of plant density.
PREMISE OF STUDY The factors driving variation in species interactions are often unknown, and few studies have made a link between changes in interactions and the strength of selection. METHODS We report on spatial variation in functional responses by a seed predator (SP) and its parasitic wasps associated with the herb Ruellia nudiflora. We assessed the influence of plant density on consumer...
