Population genetic effects of human mediated plant range expansions on native phytophagous insects
Article Abstract:
Anthropogenic changes in organismal distributions have affected many terrestrial ecosystems and Anthropogenic plant range expansions (APREs) may have found effects on the population genetics of native phytophagous insects exploiting recent changes in plant distributions. The future approaches for addressing the impact of APREs on native phytophagous insect ecology and application of the concepts of population genetic change and resultant outcomes to research outside plant insect interactions are outlined.

Aggregation, intraguild interactions and the coexistence of competitors on small ephemeral patches
Article Abstract:
A simulation model is developed to explore the influence of aggregation on coexistence in communities of species competing for patchy ephemeral resources. The results have highlighted the mechanisms that are likely to influence diversity in communities exploiting patchy resources, as the resource heterogeneity, intraspecific aggregation and intraguild predation (IGP) are all common phenomena.

Strong interactions between species of phytophagous fly: a case of intraguild kleptoparasitism
Article Abstract:
The role of interspecific competition in phytophagous insect communities is investigated. The modification of the competitive interaction between two species of gall forming fly, Lipara lucens and Lipara rufitarsis, as a consequence of interactions with a host plant and natural enemies is described.
