Development of roads can have deleterious effects on natural habitats containing species of conservation concern. Fragmentation of habitat into small, non-contiguous patches may result in dramatic population declines. Thus appropriate studies quantifying ecological impacts of roads at landscape scale are essential. In this study, the Spatial Road Disturbance Index (SPROADI) was applied for the ...
Deformed amphibians have been observed in the Kenai National Wildlife Refuge, Alaska. Environmental variables such as contaminants, ultraviolet radiation [UV], or parasites may cause deformities. It is important to identify the environmental cause of deformities in order that effective management strategies can be implemented to enable the recovery of affected populations. To determine whether ...
