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...

Use and characteristics of the minor rural road network have changed dramatically in West-European intensive agricultural landscapes. These changes are caused by modern agriculture, by changing values of the road’s verges and by the multifunctionalization of the rural landscape. Changing the network, conventional farming practices often decrease landscape ecological stability. These problems ca...

The 26 sample sites in 7 study plots adjacent to asphalt road and earth road in coastal wetland in the Yellow River Delta were selected to quantify plant diversity using quadrat sampling method in plant bloom phase of July and August 2012. The indice of β T and Jaccard's coefficient were applied to evaluate the species diversity. The results showed that the plant diversities and alien plants we...

17 Road verges have been proposed as refuges for vulnerable grassland species in the 18 modern, changing landscape, but little comparative knowledge exists on how 19 management regimes affect population dynamics of such species. We compared the 20 effects of various management regimes on population dynamics of Pimpinella saxifraga 21 in road verges and pastures, using elasticities and LTRE-anal...

There is growing societal and scientific interest in enhancing road verges for nature the environment. This partly because they are estimated to cover large areas some regions. Yet, our knowledge, there has been no quantitative assessment of national verge extent, or habitats encompass. We present a novel method characterising classifying remotely. use this evaluate extent habitat composition a...

CONTEXT Anthropogenic vectors enhance the natural dispersal capacity of plant seeds significantly in terms of quantity and distance. Human-mediated seed dispersal (i.e. anthropochory) greatly increases the dispersal of crop species across agroecosystems. In the case of oilseed rape (OSR), spillage of seeds from grain trailers during harvest has never been quantified. METHODS Our experimental ...

Urbanization and related anthropogenic modifications cause extent of habitat fragmentation and directly lead to decline of local biodiversity. Conservation biologists advocate corridor creation as one approach to rescue biodiversity. Here we examine the utility of roads as corridors in preserving plant diversity by investigating roadside vegetation in Yellow River Delta (YRD), China. We examine...

Previous studies suggest that eastern chipmunks (Tamias striatus) avoid roads, but it is unclear whether vehicle traffic plays a role in this avoidance. The purpose of this study was to determine whether road avoidance in chipmunks increases with traffic. We tracked the movements of 68 chipmunks released near roads with widely varying volumes of traffic. Our results suggest that chipmunks respo...
