Abstract:

Ecological studies on road’s impact on wildlife have concentrated on vertebrates although less is known of their effects on invertebrates. The current study presents public road influences on species richness, abundance, and diversity of ground dwelling insects in Arusha National Park in Tanzania. Values from pitfall traps data were generally higher in core habitat than road verge. Nine species were only found in road verge and twenty eight species found only in core habitat. Results also show significant differences p≤0.01 in species richness, abundances and diversity of ground-dwelling insects, between road verge and core habitat with greater values for core area, where soil acidity was low and cation exchange capacity was high. Results suggest that high soil pH, relative to low soil pH, provides good conditions for different insects species. These findings provide evidence on the effect of public roads on distribution of wildlife communities in protected area and hence call for proper road design and management of established roads in protected areas.

Road networks predict human influence on Amazonian bird communities.

Road building can lead to significant deleterious impacts on biodiversity, varying from direct road-kill mortality and direct habitat loss associated with road construction, to more subtle indirect impacts from edge effects and fragmentation. However, little work has been done to evaluate the specific effects of road networks and biodiversity loss beyond the more generalized effects of habitat ...

The Role of Small Woodland Remnants on Ground Dwelling Insect Conservation in Chaco Serrano, Central Argentina

Many terrestrial ecosystems are changing due to extensive land use and habitat fragmentation, posing a major threat to biodiversity. In this study, the effects of patch size, isolation, and edge/interior localization on the ground dwelling insect communities in the Chaco Serrano woodland remnants in central Argentina were examined. Sampling was carried out in December 2003 and March 2004 in nin...
