Road size and carrion beetle assemblages in a New York forest

摘要: In many parts of the world, roads are most common causes forest fragmentation. We know can affect wildlife, but understand little extent to which these effects depend on road type and use. compared several types upon a diverse, carrion frequenting beetle assemblage in rural New York State. found no consistent distance from diversity, abundance or species density beetles across types. However, forests near highways two-lane paved were significantly less diverse than dirt roads. The reduced diversity was at least part due lower turnover space either Our data suggest that all not created equal comparably sized minimum-use have substantially greater fauna Highways appear depress biodiversity even among relatively vagile animals like beetles.
