Název v původním jazyce

Roads do not increase predation on experimental nests in a highly fragmented forest land

Popis výsledku v původním jazyce

Modern forestry may alter avian reproductive success indirectly through affecting predator-prey interactions. Here we evaluate the influence of road types on nest predation in a highly fragmented forest area interspersed by a dense network of roads, withone third of the area covered by a red-deer enclosure. Experimental nests were installed along three types of roads discriminated by utility and inside/outside the red-deer enclosure. The nests were placed in couples, with one nest placed close to the road edge and the second placed inside the forest habitat to assess the ?travel line? hypothesis. The ?travel line? hypothesis was not supported because there was a similar predation rate among edge and interior nests. Even if predators can be discouragedalong busy roads, type of road also did not affect nest predation. Nest predation inside the enclosure was significantly lower, suggesting that frequent disturbances in these habitats may have a repellent effect on nest predators.
