- Effects of earthworms and organic litter distribution on plant performance and aphid reproductionSusanne Wurst
Institut fur Zoologie, Technische Universitat Darmstadt, Schnittspahnstrasse 3, 64287 Darmstadt, Germany
Oecologia 137:90-6. 2003..Aphid (Myzus persicae) reproduction was reduced on P. lanceolata in the presence of earthworms. We suggest that earthworm activity may indirectly alter plant chemistry and hence defence mechanisms against herbivores...
- Soil microbial diversity and soil functioning affect competition among grasses in experimental microcosmsMichael Bonkowski
Centre d Ecologie Fonctionnelle et Evolutive, CNRS, 1919 Route de Mende, 34293 Montpellier, France
Oecologia 143:232-40. 2005..The results further suggests that small trade-offs in plant fitness due to general functional shifts at the microbial level can be significant for the outcome of competition in plant communities and thus diversity at much larger scales...
- Decoupling the direct and indirect effects of nitrogen deposition on ecosystem functionPete Manning
Natural Environment Research Council Centre for Population Biology, Department of Biological Sciences, Imperial College London, Silwood Park Campus, Ascot, Berkshire SL5 7PY, UK
Ecol Lett 9:1015-24. 2006..These findings suggest that direct effects of N deposition on ecosystem function could be relatively strong in comparison with the indirect effects of plant community change...
