Stability of pitcher-plant microfaunal population depends on food web structure

Article Abstract:

A study was conducted to test the effect of stability of microfaunal populations living in the pitcher plants by varying resources and number of omnivorous predators. The result showed that both top-down factors like (omnivorous mosquitoes) and bottom-up factors (enrichment) influence the stability of pitcher plant microfaunal populations which further suggest that omnivory and other food web complexities could eliminate the paradox of enrichment seen in simpler food webs.

Changing importance of habitat structure across multiple spatial scales for three species of insects

Article Abstract:

The effects of habitat configuration (patch size and isolation) on the density of three species of insects are examined. The hierarchical frameworks are important for the understanding of the response of species to habitat structure and their role in ecosystem function.

The timing of egg maturation in insects: Ovigeny index and initial egg load as measures of fitness and of resource allocation

Article Abstract:

The lifetime of egg maturation in insects is evaluated. The ovigeny index and initial egg load as measures of fitness and of resource allocation are focused.
