Habitat fragmentation effects on trophic processes of insect-plant food webs.
Habitat fragmentation is the transformation of once-extensive landscapes into smaller isolated remnants surrounded by new types of habitat. There is ample evidence of impoverished biodiversity as aExpand

Quantitative food webs of dipteran leafminers and their parasitoids in Argentina
The quantitative structure of two host–parasitoid communities based on leaf-mining flies (Diptera, Agromyzidae) in Argentina is described. The two communities consisted of 29 and 27 hosts, 46 and 40Expand

Phytochemical induction by herbivores could affect quality of essential oils from aromatic plants.
Plant tissues may show chemical changes following herbivory. In aromatic plants such changes could affect the specific compounds on which commercial exploitation is based. This possibility wasExpand
